存在使混动模块尽可能节约结构空间地匹配于狭窄的结构空间情况的持久的需求。There is a constant need to adapt the hybrid module to the constricted installation space situation in a way that saves installation space as much as possible.

发明内容Contents of the invention

本实用新型的目的是揭示能够实现使混动模块以节约结构空间的方式匹配于狭窄的结构空间情况的措施。The purpose of the utility model is to disclose measures that can realize the adaptation of the hybrid module to the narrow construction space in a structural space-saving manner.

所述目的根据本实用新型的离合器设备来实现。Said object is achieved according to the clutch device of the invention.

根据本实用新型提出一种用于将内燃机减振地耦联到机动车的动力总成上的离合器设备，所述离合器设备用于混动模块，具有：扭振减振器，用于衰减转动不均匀性；在扭振减振器处经由可松开的、尤其构成为插接啮合装置的耦联装置以传输扭矩和可轴向彼此移动的方式耦联的携动环，用于传递衰减的扭矩；与携动环连接的分离离合器，用于将衰减的扭矩选择性地传输到轴上；和连接元件，尤其用于曲轴旋拧装置的连接元件，用于将扭振减振器与内燃机的驱动轴直接地或间接地固定，其中耦联装置设置在连接元件的径向外部并且携动环在连接元件的径向内部在扭振减振器处支承和/或定心，或者耦联装置设置在连接元件的径向内部并且携动环在连接元件的径向外部在扭振减振器处支承和/或定心。According to the present invention, a clutch device is proposed for coupling an internal combustion engine to a powertrain of a motor vehicle in a vibration-damping manner, said clutch device being used in a hybrid module, having a torsional vibration damper for damping rotation Inhomogeneity; drive rings on the torsional vibration damper via a detachable coupling, in particular designed as a plug-in toothing, for torque transmission and axially displaceable coupling to one another for transmission of damping torque; a disconnecting clutch connected to the drive ring for selectively transmitting the damped torque to the shaft; and a connecting element, especially for a crankshaft screwing device, for connecting the torsional vibration damper to the The drive shaft of the internal combustion engine is fixed directly or indirectly, wherein the coupling device is arranged radially outside the connecting element and the drive ring is supported and/or centered on the torsional vibration damper radially inside the connecting element, or coupled The coupling is arranged radially inside the connecting element and the drive ring is mounted and/or centered on the torsional vibration damper radially outside the connecting element.

尤其构成为在扭振减振器和分离离合器之间的插接啮合装置的耦联装置可以构成在一方面扭振减振器和另一方面分离离合器之间的分离部位。由此，扭振减振器和分离离合器作为单独的结构单元依次装入混动模块和/或机动车的动力总成中，并且经由轴向的相对运动在安装时彼此连接。因为在耦联装置中仅应传输扭矩并且不设有轴向支撑，所以耦联装置可以相应简单地并且仅为了能够实现传输扭矩的目的构成，尤其作为插接啮合装置。在运行进行中，也可以允许在耦联装置之内的相对运动，例如以便避免或至少衰减轴向振动的传输。在耦联装置中切向贴靠的结构元件可相对于彼此轴向相对移动地构成，其中轴向的可相对移动性例如通过减小摩擦的覆层、适合的润滑或其他方式改进。这能够实现经由耦联装置将分离离合器的可轴向移置的构件以传输扭矩的方式在耦联装置中耦联。分离离合器例如可以具有在反压板和可轴向相对移置的压板之间可压紧的离合器盘，所述离合器盘应可尽可能地在小的轴向行程上轴向移置，以便在摩擦离合器的断开状态中可以从轴向固定的反压板抬起。由此，此外可以避免不需要的拖曳力矩并且实现离合器盘的摩擦衬的足够的磨损区域。这能够经由在耦联装置中的轴向可移置性来实现，而对离合器盘的轴向可移置性不设有单独的耦联机构。In particular, the coupling device, which is designed as a plug-in engagement between the torsional vibration damper and the separating clutch, can form a separation point between the torsional vibration damper on the one hand and the separating clutch on the other. As a result, the torsional vibration damper and the separating clutch are integrated successively as separate structural units into the hybrid module and/or the powertrain of the motor vehicle and are connected to one another via axial relative movements during assembly. Since only torque is to be transmitted in the coupling and no axial support is provided, the coupling can be designed correspondingly simply and only for the purpose of enabling torque transmission, in particular as a plug-in engagement. During operation, relative movements within the coupling device can also be permitted, for example in order to avoid or at least dampen the transmission of axial vibrations. In the coupling device, the structural elements abutting tangentially can be designed to be axially displaceable relative to one another, wherein the relative axial displaceability is improved, for example, by a friction-reducing coating, suitable lubrication or otherwise. This makes it possible to couple the axially displaceable components of the separating clutch in the coupling device via the coupling device in a torque-transmitting manner. The separating clutch can have, for example, a clutch disc that can be compressed between a counter pressure plate and a pressure plate that is displaceable axially relative to each other, the clutch disc should be axially displaceable over as small an axial stroke as possible in order to reduce friction In the disengaged state of the clutch, it can be lifted from the axially fixed counterplate. In this way, unnecessary drag torques can also be avoided and a sufficient wear area of the friction lining of the clutch disk can be achieved. This can be achieved via the axial displaceability in the coupling device without a separate coupling mechanism being provided for the axial displaceability of the clutch disc.

耦联装置和携动环的支承/定心沿径向方向彼此错开地设置，其中尤其是曲轴旋拧装置的一部分的连接机构沿径向方向设置在其之间。至少一个连接机构设置在半径区域中，在所述半径区域之外设有耦联装置以及携动环的支承/定心。在下文中本实用新型示例性地以一个尤其优选的实施方式的实例来描述，其中耦联装置在连接机构的径向外部设置并且支承/ 定心在连接机构的径向内部设置。下面的阐述然而大部分也适用于如下变型形式，其中耦联装置在连接机构的径向内部设置并且支承/定心在连接机构的径向外部设置。The bearing/centering of the coupling device and the driver ring is arranged offset to one another in the radial direction, wherein in particular the connecting means of a part of the crankshaft screwing device are arranged between them in the radial direction. At least one connecting means is arranged in a radius region outside which the coupling device and the mounting/centering of the drive ring are provided. In the following the invention is described by way of example as an example of a particularly preferred embodiment in which the coupling device is arranged radially outside the connection and the bearing/centering is arranged radially inside the connection. However, most of the explanations below also apply to variants in which the coupling device is arranged radially inside the connecting means and the mounting/centering is arranged radially outside the connecting means.

因为在一个尤其优选的实施方式中，耦联装置在连接机构的径向外部设置，所以耦联装置一方面设置在小的半径上，使得耦联装置不会干扰扭振减振器的其他构件，并且另一方面设置在大的半径上，使得可以无问题地传输大的扭矩。与耦联装置设置在连接机构的径向内部的布置相比，可以设有更大数量的由耦联装置构成的插接啮合装置的齿，由此在齿的材料负荷小的情况下可以传输高的扭矩。通过携动环在连接机构的径向内部设置的、尤其在扭振减振器的输入侧处的支承或定心，为此设置的结构性的机构能够设置在相对小的半径上，由此可以降低制造成本。尤其地，由此可行的是，支承或定心移置离开连接机构的径向外部的半径区域，由此可以实现在连接机构的径向外部的结构空间，所述结构空间尤其可以由耦联装置基本上结构空间中性地使用。此外，耦联装置也可以满足一定的定心功能，使得例如在连接机构的径向外部在耦联装置中可以实现携动环的粗定心并且在连接机构的径向内部可以实现携动环的精定心。离合器设备通过携动环和分离离合器相对于扭振减振器的相对运动进行的安装可以由此简化。此外，通过径向外部的耦联装置距径向内部的支承/定心的径向间距，可以更好地避免或至少更大程度地限制携动环围绕径向伸展的倾斜轴线的倾斜。通过耦联装置与携动环的支承/定心的径向错开，在安装友好性改进的情况下可以实现可用的结构空间，使得能够实现使混动模块以节约结构空间的方式匹配于狭窄的结构空间情况。Since in a particularly preferred embodiment the coupling device is arranged radially outside the connecting means, the coupling device is arranged on the one hand on a small radius, so that the coupling device does not interfere with other components of the torsional vibration damper. , and on the other hand are arranged on a large radius, so that large torques can be transmitted without problems. Compared with an arrangement in which the coupling device is arranged radially inside the connection, a greater number of teeth of the plug-in toothing formed by the coupling device can be provided, so that the transmission can be carried out with a low material load on the teeth. high torque. The structural means provided for this can be arranged on a relatively small radius by means of the mounting or centering of the drive ring arranged radially inside the connection, in particular on the input side of the torsional vibration damper, whereby Manufacturing cost can be reduced. In particular, this makes it possible to displace the bearing or the centering away from the radially outer radius region of the connecting means, whereby an installation space radially outer of the connecting means can be realized, which can in particular be provided by the coupling The device is substantially space-neutral in use. In addition, the coupling device can also fulfill a certain centering function, so that, for example, a rough centering of the driver ring can be realized in the coupling device radially outside the connection and a driver ring can be realized radially inside the connection. fine mind. Mounting of the clutch arrangement by means of the relative movement of the driver ring and the separating clutch relative to the torsional vibration damper can thus be simplified. Furthermore, due to the radial spacing of the radially outer coupling device from the radially inner mounting/centering, tilting of the driver ring about the radially extending tilting axis can be better avoided or at least limited to a greater extent. Due to the radial offset of the mounting/centering of the coupling device and the driver ring, the available installation space can be achieved with improved installation friendliness, making it possible to adapt the hybrid module to narrow installation spaces in a space-saving manner. The structural space situation.

扭矩减振器可以具有单独的或一件式的毂，用于构成用于耦联装置的内齿部。毂可以具有沿轴向方向的足够的延伸，以便即使在耦联装置的与分离离合器连接的输出侧的耦联元件的要预期的轴向相对位置不同的情况下可以传输限定的最大力矩。此外，施加的力可以在毂的纵向延伸上分布，使得得出较小的局部法向力和在轴向相对移动时在耦联装置之内出现的较小的摩擦力。优选地，毂的轴向延伸或内齿部的轴向延伸可以超出对于可靠地传输预定的最大扭矩所需要的轴向延伸过大尺寸地设计，例如以至少1.5倍、优选至少2.0倍和尤其优选至少3.0倍。最大的轴向延伸通常通过在离合器设备之内的可用的轴向结构空间限制。尤其优选地，毂轴向地在扭振减振器的另一构件处、尤其在双质量飞轮的初级质量处支撑，其中尤其对此设有滑动轴承，所述滑动轴承允许相对转动。此外可行的是，毂例如至少经由粗定心在另一构件处径向定向，尤其定心。通过离合器盘在扭振减振器的输入侧处的引导和支承，在机动车的纯电驱动时避免经由轴的拖曳损耗。The torque damper can have a separate or one-piece hub for forming the internal toothing for the coupling device. The hub can have a sufficient extension in the axial direction to be able to transmit a defined maximum torque even if the desired axial relative positions of the coupling elements of the output side of the coupling device connected to the separating clutch are different. In addition, the applied forces can be distributed over the longitudinal extension of the hub, so that there are lower local normal forces and lower frictional forces occurring within the coupling device during the axial relative movement. Preferably, the axial extension of the hub or the axial extension of the internal toothing can be oversized beyond the axial extension required for reliable transmission of a predetermined maximum torque, for example by a factor of at least 1.5, preferably by a factor of at least 2.0 and especially Preferably at least 3.0 times. The maximum axial extension is usually limited by the available axial installation space within the clutch device. Particularly preferably, the hub is supported axially on another component of the torsional vibration damper, in particular on the primary mass of the dual-mass flywheel, wherein in particular a slide bearing is provided for this, which allows a relative rotation. It is also possible for the hub to be radially aligned, in particular centered, on the other component, for example at least via rough centering. Through the guidance and mounting of the clutch disc on the input side of the torsional vibration damper, drag losses via the shaft are avoided during purely electric drive of the motor vehicle.

为了可以满足越来越严的排放标准以及要求的最大油耗，几乎全部汽车制造商注重动力总成的混动化。为了节约重量和结构空间，电动机直接置于尤其构成为燃烧器的内燃机的例如构成为扭转减振器的扭振减振器后面或者(混动的)双离合变速器中。两个驱动器的分离借助于分离离合器进行。在该情况下也称作为K0离合器的分离离合器应尽可能结构空间中性地实现并且尽可能好地与减振器组合，这可以通过在连接元件的径向外部设置的耦联装置实现。为了实现对绝缘的高的要求，扭振减振器应具有双质量飞轮和/或离心摆(FKP)，其应尽可能结构空间中性地集成。因为设为用于衰减扭振的部件为了实现高的衰减能力应尽可能径向靠外设置，所以在扭振减振器的径向内部边缘留有足够的结构空间，以便基本上结构空间中性地在连接元件的径向外部能设置耦联装置。在尤其构成为扭转振动减振器的扭振减振器和分离离合器之间的接口的这样实现的改进由此基本上结构空间中性地实现。In order to meet increasingly stringent emission standards and the required maximum fuel consumption, almost all automakers focus on the hybridization of powertrains. In order to save weight and installation space, the electric motor is placed directly downstream of a torsional vibration damper, for example as a torsional vibration damper, of the internal combustion engine, in particular as a burner, or in a (hybrid) dual clutch transmission. The two drives are separated by means of a separating clutch. The separating clutch, which is also referred to as the K0 clutch in this case, should be realized as structurally space-neutral as possible and combined with the damper as best as possible, which can be achieved by means of a coupling arranged radially outside the connecting element. In order to meet the high demands on insulation, the torsional vibration damper should have a dual-mass flywheel and/or a centrifugal pendulum (FKP), which should be integrated as structurally space-neutral as possible. Since the components provided for damping torsional vibrations should be arranged as radially outward as possible in order to achieve a high damping capacity, there is sufficient installation space at the radially inner edge of the torsional vibration damper so that essentially the installation space Optionally, the coupling device can be arranged radially outside the connecting element. The improvement achieved in this way of the interface between the torsional vibration damper, in particular embodied as a torsional vibration damper, and the separating clutch is thereby achieved substantially in a space-neutral manner.

尤其地，在连接元件的径向内部设有尤其与扭振减振器固定的径向滑动轴承，用于将携动环径向地支承在扭振减振器处。通过径向滑动轴承，同时可以实现携动环在扭振减振器处的支承和精定心。必要时，也可以设有连接于径向滑动轴承的轴向滑动轴承，用于将携动环轴向支承在扭振减振器处。In particular, a radial slide bearing, in particular fixed to the torsional vibration damper, is provided radially inside the connecting element for radially supporting the driver ring on the torsional vibration damper. Supporting and fine centering of the driver ring on the torsional vibration damper can be achieved at the same time by means of the radial plain bearing. Optionally, an axial slide bearing connected to the radial slide bearing can also be provided for axially supporting the driver ring on the torsional vibration damper.

优选地，在连接元件的径向外部设有尤其与扭振减振器固定的轴向滑动轴承，用于将携动环轴向地支承在扭振减振器处。轴向滑动轴承尤其可以设置在具有耦联装置的半径区域中。根据轴向相对位置，携动环可以在轴向滑动轴承处运行和支承，使得由携动环表现出的轴向负载可以容易地经由轴向滑动轴承支撑。尤其优选地，轴向滑动轴承在扭振减振器的输入侧的部分和扭振减振器的输出侧的部分之间防丢失地容纳，尤其可相对转动地夹紧，所述扭振减振器尤其也可以形成耦联装置的一部分。轴向滑动轴承的轴向相对位置由此与可轴向移置的携动环的轴向位置无关地可靠地预设。此外甚至可行的是，轴向滑动轴承可以起到将在扭振减振器中构成的容纳空间密封的作用。Preferably, an axial slide bearing, in particular fixed to the torsional vibration damper, is provided radially on the outside of the connecting element for axially supporting the driver ring on the torsional vibration damper. In particular, the axial plain bearing can be arranged in the radius region with the coupling device. Depending on the axial relative position, the driver ring can be run and supported on the axial plain bearing, so that the axial loads exhibited by the driver ring can easily be supported via the axial plain bearing. Particularly preferably, the axial slide bearing is held between the input-side part of the torsional vibration damper and the output-side part of the torsional vibration damper, in particular clamped in a relatively rotatable manner, said torsional vibration damper In particular, the vibrator can also form part of the coupling device. The axial relative position of the axial slide bearing is thereby reliably preset independently of the axial position of the axially displaceable driver ring. Furthermore, it is even possible for the axial plain bearing to seal off the receiving space formed in the torsional vibration damper.

尤其优选地，分离离合器具有在反压板和相对于反压板可轴向移置的压板之间可压紧的离合器盘，其中离合器盘与携动环固定。通过携动环可行的是，分离离合器在径向外部设置并且扭矩从在分离离合器的径向内部的半径区域中构成的耦联装置传输到更大的半径上。由此，在分离离合器的径向内部留有可用的结构空间。从扭振减振器经由分离离合器到轴上的扭矩流不需要从反压板和/或从压板到离合器盘和轴上进行，而是首先可以经由离合器盘伸展到反压板和/或压板上并且从那里开始伸展到轴上。离合器盘应尽可能地在小的轴向行程上可轴向移置，以便在摩擦离合器的断开状态中可以从轴向固定的反压板抬起。这能够经由在耦联装置中的轴向可移置性来实现，而对离合器盘的轴向可移置性不设有单独的耦联机构。Particularly preferably, the separating clutch has a clutch disk that can be compressed between a counterplate and a pressure plate that is axially displaceable relative to the counterplate, wherein the clutch disk is fixed to the drive ring. The driver ring makes it possible to arrange the separating clutch radially on the outside and to transmit torque from the coupling device formed in the radially inner radius region of the separating clutch to a larger radius. As a result, available installation space remains radially inside the separating clutch. The torque flow from the torsional vibration damper via the separating clutch to the shaft does not need to take place from the counter pressure plate and/or from the pressure plate to the clutch disc and the shaft, but can firstly extend via the clutch disc to the counter pressure plate and/or the pressure plate and From there start stretching to the axis. The clutch disk should be axially displaceable with as little axial travel as possible in order to be able to lift off the axially fixed counterplate in the disengaged state of the friction clutch. This can be achieved via the axial displaceability in the coupling device without a separate coupling mechanism being provided for the axial displaceability of the clutch disc.

尤其地，携动环具有包围连接元件的毂单元和与毂单元经由固定机构固定的携动盘，其中毂单元在径向外部的外管件处尤其经由外齿部在耦联单元中耦联，并且在径向内部的内管件处在扭振减振器处支承和/或定心，或者毂单元在径向内部的内管件处尤其经由外齿部在耦联单元中耦联，并且在径向外部的外管件处在扭振减振器处支承和/或定心。毂单元例如可以通过无切屑的改型，例如深冲，由尤其冲出的钢环成本适宜地产生，其中在外管件的径向内部的侧表面或径向外部的侧表面处的齿部同样可以通过切削的生产方法产生。通过携动环到毂单元和携动盘中的构件分离，用于毂单元的外齿部的制造和尤其生产可以简化，由此可以将制造成本保持得低。用于将毂单元与携动盘借助于固定机构、尤其通过铆接固定的固定技术在此可以设置在如下半径区域中，所述半径区域允许固定机构轴向突出，而不损坏扭振减振器的构件。在此，利用如下知识，如果扭振减振器已经借助于至少一个连接元件与内燃机的驱动轴耦联，那么在安装离合器设备时才将分离离合器与扭振减振器结合，使得携动环的固定机构沿轴向方向可以非常接近扭振减振器与驱动轴的尤其构成为曲轴旋拧装置的连接装置的连接元件。由此可用的结构空间可以优化地使用。In particular, the driver ring has a hub unit surrounding the connecting element and a driver disk fastened to the hub unit via fastening means, wherein the hub unit is coupled in the coupling unit at the radially outer outer tube, in particular via an external toothing, And the radially inner inner tube is supported and/or centered at the torsional vibration damper, or the hub unit is coupled at the radially inner inner tube in the coupling unit, in particular via an external toothing, and the radially inner The outer tubular part facing outwards is supported and/or centered on the torsional vibration damper. For example, the hub unit can be produced cost-effectively from an in particular punched steel ring by chip-free modification, for example deep drawing, wherein the toothing on the radially inner side surface or the radially outer side surface of the outer tubular part can likewise be Produced by cutting production methods. The separation of the driver ring into the components of the hub unit and the driver disk simplifies the manufacture and in particular the production of the external toothing for the hub unit, so that the manufacturing costs can be kept low. The fastening technique for fastening the hub unit to the driver disk by means of fastening means, in particular by riveting, can be provided in a radius region which allows the fastening means to protrude axially without damaging the torsional vibration damper components. In this case, the knowledge that the torsional vibration damper is already coupled to the drive shaft of the internal combustion engine by means of at least one connecting element is used to couple the separating clutch to the torsional vibration damper when installing the clutch arrangement, so that the drive ring The fastening means can be very close in the axial direction to the connecting element of the torsional vibration damper to the drive shaft, in particular formed as a connecting device of a crankshaft screwing device. The available installation space can thus be used optimally.

优选地，携动盘从径向内部朝向径向外部具有远离扭振减振器弯折的走向。由此，实现在携动环的一部分的径向内部的结构空间，所述结构空间可以由其他构件使用，以便节约轴向的结构空间。Preferably, the driver disk has a course that is bent away from the torsional vibration damper from the radially inner side to the radially outer side. As a result, an installation space is created radially inside a part of the driver ring, which can be used by other components in order to save axial installation space.

尤其优选地，设有具有压力腔的液压执行器，用于操作分离离合器，其中压力腔至少部分地设置在与分离离合器共同的轴向区域中，其中尤其压力腔至少部分地设置在与携动环共同的轴向区域中。执行器可以在分离离合器和/或携动环的径向内部完全地或部分地插入到其余的离合器设备的径向内部实现的结构空间中，使得得出嵌套的构造。轴向的结构空间需求由此可以保持得低。在此，利用如下知识，尤其在用于混动机动车的动力总成中，应在输出侧耦联的构件通常与在径向外部相比在径向内部更需要结构空间。因为分离离合器和携动环不在径向内部、而是至少部分地在径向外部设置，所以轴在输出侧的接合部沿轴向方向尤其靠近内燃机的与扭振减振器连接的驱动轴、尤其曲轴设置，并且沿轴向方向相应远地伸入到离合器设备中。同时，分离离合器和携动环甚至在径向外部定位成，使得用于操作分离离合器的执行器也还能够伸入到其余的离合器设备中。分离离合器和携动环沿径向方向观察能至少部分地遮盖执行器的压力腔。分离离合器和耦联装置可以从径向外部起包围轴和执行器，由此可以实现尤其紧凑的和节约结构空间的动力总成。Particularly preferably, a hydraulic actuator with a pressure chamber is provided for actuating the separating clutch, wherein the pressure chamber is arranged at least partially in the same axial region as the separating clutch, wherein in particular the pressure chamber is at least partially arranged in the same axial region as the driving clutch. in the common axial region of the rings. The actuator can be completely or partially inserted radially inside the separating clutch and/or the driver ring into the installation space realized radially inside the rest of the clutch arrangement, so that a nested configuration results. The axial installation space requirement can thus be kept low. In this case, the knowledge is used that, especially in powertrains for hybrid vehicles, components that are to be coupled on the output side generally require more installation space radially inside than radially outside. Since the separating clutch and the driver ring are not arranged radially inward, but at least partially radially outward, the joint of the shaft on the output side is located in the axial direction in particular close to the drive shaft of the internal combustion engine, which is connected to the torsional vibration damper, In particular, the crankshaft is arranged and protrudes correspondingly far into the clutch arrangement in the axial direction. At the same time, the separating clutch and the driver ring are even positioned radially on the outside, so that the actuator for actuating the separating clutch can also protrude into the rest of the clutch arrangement. Viewed in the radial direction, the separating clutch and the driver ring can at least partially cover the pressure chamber of the actuator. The isolating clutch and the coupling device can surround the shaft and the actuator from the radial outer side, whereby a particularly compact and space-saving powertrain can be achieved.

尤其地，执行器的在压力腔中可轴向移动地容纳的活塞设置在携动环的固定元件的径向外部的半径区域中，其中尤其执行器的执行器壳体具有朝向扭振减振器敞开的凹部，用于容纳固定元件的一部分。压力腔和执行器的活塞可以在径向外部设置，使得在活塞的径向内部，执行器可以具有轴向缩窄部，所述轴向缩窄部可以构成用于携动环的连接元件的凹部。借助于固定元件实现的连接技术由此可以基本上结构空间中性地实现。In particular, the piston of the actuator, which is accommodated axially displaceably in the pressure chamber, is arranged in the radially outer radius region of the fastening element of the drive ring, wherein in particular the actuator housing of the actuator has a direction towards the torsional vibration damping An open recess for receiving a portion of a fixing element. The pressure chamber and the piston of the actuator can be arranged radially on the outside, so that radially inside the piston the actuator can have an axial constriction which can form a connection element for the driver ring. recessed part. The connection technology by means of the fastening element can thus be implemented substantially in a space-neutral manner.

优选地，与分离离合器、尤其与分离离合器的压板连接的压力盘与活塞连接，其中压力盘轴向地遮盖耦联装置和分离离合器的至少大部分。借助于压力盘，在径向内部在压力腔中产生的操作力可以传输给分离离合器的在径向外部设置的压板。压力盘沿轴向方向可以具有极其小的材料厚度，使得轴向结构空间需求保持得低。同时，压力盘可以至少部分地侧向地覆盖分离离合器并且抵御变速器侧的污物进入。离合器盘和耦联装置在此可以与压力盘轴向间隔开地设置。Preferably, a pressure plate connected to the separating clutch, in particular to a pressure plate of the separating clutch, is connected to the piston, wherein the pressure plate axially covers at least a large part of the coupling device and the separating clutch. The radially inner actuating force generated in the pressure chamber can be transmitted to the radially outer pressure plate of the separating clutch by means of the pressure plate. The pressure plate can have an extremely small material thickness in the axial direction, so that the axial installation space requirement remains low. At the same time, the pressure plate can at least partially cover the separating clutch laterally and protect against the ingress of dirt on the transmission side. The clutch disk and the coupling device can be arranged axially spaced apart from the pressure disk.

尤其执行器与轴抗扭地固定，其中尤其轴具有用于用液压介质、尤其油加载执行器的压力腔的供应通道。通过在轴处的机械支撑，出现的力可以经由轴支撑，尤其当执行器的执行器壳体用于传输扭矩时如此。与扭振减振器借助于连接元件固定的驱动轴的支承由此被减轻负荷。在轴中设置的供应通道例如可以通过沿轴向方向伸展的盲孔和从盲孔径向向外离开的、尤其通到在轴的径向外环周处设置的环形槽中的连接孔组成。压力腔由此可以从径向内部起用液压介质加载，所述液压介质例如在轴的背离扭振减振器的轴向端部处馈送，使得节约轴向间隔开地在分离离合器旁经过的液压管路。轴向的结构空间需求由此可以保持得低。In particular, the actuator is fastened to the shaft in a rotationally fixed manner, wherein in particular the shaft has a supply channel for charging the pressure chamber of the actuator with a hydraulic medium, in particular oil. Due to the mechanical support at the shaft, the forces occurring can be supported via the shaft, in particular if the actuator housing of the actuator is used for torque transmission. The bearing of the drive shaft, which is fixed to the torsional vibration damper by means of the connecting element, is thereby relieved of load. The supply channel provided in the shaft can be formed, for example, by a blind bore extending in the axial direction and a connecting bore leading radially outward from the blind bore, in particular into an annular groove provided at the radially outer circumference of the shaft. The pressure chamber can thus be acted upon radially from the inside with hydraulic medium, which is fed, for example, at the axial end of the shaft facing away from the torsional vibration damper, so that the hydraulic pressure passing past the separating clutch at an axial distance is saved. pipeline. The axial installation space requirement can thus be kept low.

The piston of the actuator can thus be moved out on the axial side facing away from the torsional vibration damper, so that an actuating force can also be directed to the separating clutch on the axial side facing away from the torsional vibration damper. As a result, the power path for the actuating force of the separating clutch is guided past the coupling device and/or the drive ring without interfering with each other.

The axial installation space requirement is thus kept low. In particular, the centrifugal pendulum is arranged substantially centrally in the axial direction relative to the energy storage element, so that the axial installation space requirement for the torsional vibration damper remains low. Preferably, the secondary mass forms a carrier flange for the centrifugal pendulum, on which a pendulum mass of the centrifugal pendulum can be pivotally guided.

The "zero position" is thus the radially furthest position from the center of rotation, which the pendulum mass can occupy in the radially outer position. At a constant drive rotational speed and constant drive torque, the pendulum mass assumes this radially outer position. When the rotational speed fluctuates, the pendulum deflects along its oscillating path due to its inertia. The pendulum mass can thus be moved in the direction of the center of rotation. The centrifugal force acting on the pendulum mass is thus divided into a component tangential to the pendulum track and another component normal to the pendulum track. The tangential force component provides the restoring force, which returns the pendulum mass to its "zero position", while the normal force component acts on the force introduction element, in particular the primary or secondary mass, which introduces the rotational speed fluctuations, and in the A reaction torque is generated there, which counteracts the rotational speed fluctuations and damps the introduced rotational speed fluctuations. In the case of particularly strong fluctuations in rotational speed, the pendulum mass can therefore swing out to the maximum and assume the radially innermost position. The rails arranged in the carrier flange and/or in the pendulum mass have suitable curvatures in which the coupling elements, in particular formed as rollers, can be guided. Preferably, at least two rollers are provided, which are each guided on the rolling track of the carrier flange and on the pivoting track of the pendulum mass. In particular, more than one pendulum mass is provided. Preferably, a plurality of pendulum masses are guided on the carrier flange evenly distributed in the circumferential direction. The inertia of the pendulum mass and/or the relative movement of the pendulum mass relative to the carrier flange are designed in particular to attenuate specific frequency ranges of rotational inhomogeneities of the engine arrangement, in particular of motor vehicle engines. The pendulum mass can be produced cost-effectively by means of pendulum plate packs stacked on top of each other and connected to one another, wherein in particular pendulum plates, which are preferably identically shaped, can be produced by stamping from sheet metal. In particular, more than one pendulum mass and/or more than one carrier flange are provided. For example, two pendulum masses are provided which are connected to one another via bolts or rivets, in particular designed as spacer bolts, between which a support flange is positioned in the axial direction of the torsional vibration damper. Alternatively, two, in particular substantially Y-shaped, connected flange parts of the carrier flange can be provided, between which the pendulum mass is positioned.

The clutch device can thus be part of a hybrid module which can transmit the torque generated in the internal combustion engine and the torque generated in the electric machine via a shaft to the motor vehicle transmission. If the mechanical energy of the powertrain is converted into electrical energy in the electric machine during generator operation, in particular when the vehicle is braking, that is to say the energy is recuperated, then the separating clutch can be disengaged and the drag of the torsional vibration damper and the internal combustion engine can be eliminated moment.
