一种汽车及其悬架系统Automobile and suspension system thereof

技术领域Technical Field

本发明涉及汽车的技术领域，特别涉及一种汽车及其悬架系统。The present invention relates to the technical field of automobiles, and in particular to an automobile and a suspension system thereof.

背景技术Background technique

悬架是保证乘坐舒适性的重要部件，同时，悬架又作为车架(或车身)与车轴(或车轮)之间连接的传力部件，此外，又是保证汽车行驶安全的重要部件。The suspension is an important component to ensure ride comfort. At the same time, the suspension serves as a force transmission component connecting the frame (or body) and the axle (or wheel). In addition, it is an important component to ensure the safety of vehicle driving.

良好的乘坐舒适性和宽敞的乘坐空间，是汽车设计人员一直追求的目标，现有的麦弗逊悬架、双横臂悬架及多连杆悬架等都具有良好的乘坐舒适性，但其结构复杂、成本高。立式减振器影响了乘坐空间，扭力梁悬架为半独立悬架，舒适性一般，其减振器仍然影响乘坐空间，扭杆弹簧悬架一般应用在类似皮卡这种客货两用车上，乘坐舒适性一般，结构上仍然采用现有悬架的导向机构，结构复杂。Good ride comfort and spacious riding space are the goals that automobile designers have always pursued. The existing McPherson suspension, double wishbone suspension and multi-link suspension all have good ride comfort, but their structures are complex and costly. Vertical shock absorbers affect the riding space. Torsion beam suspension is a semi-independent suspension with average comfort, and its shock absorber still affects the riding space. Torsion bar spring suspension is generally used in passenger and cargo vehicles such as pickup trucks, with average ride comfort. The structure still uses the existing suspension guide mechanism, which is complex.

因此，如何提供一种悬架系统，以简化导向结构，是本领域技术人员亟待解决的技术问题。Therefore, how to provide a suspension system to simplify the guide structure is a technical problem that needs to be solved urgently by those skilled in the art.

Obviously, the drawings described below are only embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying creative work.

具体实施方式Detailed ways

有鉴于此，本发明的核心在于提供一种悬架系统，以提高汽车的舒适性和承载能力。本发明的另一核心在于提供了一种具有上述悬架系统的汽车。In view of this, the core of the present invention is to provide a suspension system to improve the comfort and load-bearing capacity of a car. Another core of the present invention is to provide a car with the above suspension system.

为了使本技术领域的人员更好地理解本发明方案，下面结合附图和具体实施方式对本发明作进一步的详细说明。In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

如图1所示，本发明公开了一种悬架系统，其包括两个扭杆弹簧2，其中，扭杆弹簧2的一端与带车轮托架的纵臂1连接，而扭杆弹簧2的另一端与车架连接，并且这两个扭杆弹簧2平行布置。采用上述设置，利用扭杆弹簧2连接车架和车轮，通过扭杆弹簧2承受垂向载荷，即承受车身对车轮方向的载荷。由于本申请中仅通过扭杆弹簧2与车轮进行定位和导向，可简化结构，降低成本，同时还可为汽车提供更大的乘坐空间。As shown in FIG1 , the present invention discloses a suspension system, which includes two torsion bar springs 2, wherein one end of the torsion bar spring 2 is connected to a longitudinal arm 1 with a wheel bracket, and the other end of the torsion bar spring 2 is connected to a vehicle frame, and the two torsion bar springs 2 are arranged in parallel. With the above arrangement, the vehicle frame and the wheel are connected by the torsion bar spring 2, and the vertical load is borne by the torsion bar spring 2, that is, the load of the vehicle body on the wheel direction is borne. Since the present application only uses the torsion bar spring 2 to locate and guide the wheel, the structure can be simplified, the cost can be reduced, and a larger passenger space can be provided for the car.

进一步的实施例中，上述的扭杆弹簧2与纵臂1采用花键连接，而扭杆弹簧2通过扭杆座5固定在车架上。此处提供了一种扭杆弹簧2的具体连接方式，在实际中可根据不同的需要进行设置，且均在保护范围内。具体的，还可采用卡接或限位连接。In a further embodiment, the torsion bar spring 2 is spline-connected to the trailing arm 1, and the torsion bar spring 2 is fixed to the vehicle frame via a torsion bar seat 5. A specific connection method of the torsion bar spring 2 is provided here, which can be set according to different needs in practice and is within the protection range. Specifically, a clamping connection or a limit connection can also be used.

本申请中的扭杆弹簧2与纵臂1连接的一端的轴线方向通过安装在轴承座3上的轴承4限位。通过轴承4和轴承座3对扭杆弹簧2进行限位，防止扭杆弹簧2在轴线方向窜动，提高汽车的稳定性。The axial direction of one end of the torsion bar spring 2 connected to the trailing arm 1 in the present application is limited by a bearing 4 installed on a bearing seat 3. The torsion bar spring 2 is limited by the bearing 4 and the bearing seat 3 to prevent the torsion bar spring 2 from moving in the axial direction, thereby improving the stability of the vehicle.

优选的实施例中，上述的扭杆弹簧2通过扭杆座5固定在车架上，而扭杆弹簧2与扭杆座5通过花键连接。此处仅公开了一种扭杆弹簧2与车架连接的方式，采用花键连接，可保证连接的稳定性，同时保证扭杆弹簧的强度。In a preferred embodiment, the torsion bar spring 2 is fixed to the vehicle frame via a torsion bar seat 5, and the torsion bar spring 2 is spline-connected to the torsion bar seat 5. Only one method of connecting the torsion bar spring 2 to the vehicle frame is disclosed herein, and the spline connection can ensure the stability of the connection and the strength of the torsion bar spring.

此外，本申请还公开了一种汽车，包括悬架系统，具体的，该悬架系统为上述实施例中公开的悬架系统，因此，具有该悬架系统的汽车也具有上述所有技术效果，在此不再一一赘述。In addition, the present application also discloses a car, including a suspension system. Specifically, the suspension system is the suspension system disclosed in the above embodiment. Therefore, the car with the suspension system also has all the above technical effects, which will not be described one by one here.

该悬架系统的特点是两根扭杆弹簧2的长度与对应的轮距相等。具体的，两个扭杆弹簧2的长度相等，且两个扭杆弹簧2到汽车的前轴的距离不同。如此设置可获得良好的悬架刚度，使其与螺旋弹簧的独立悬架具有相同的乘坐舒适性；两根扭杆弹簧2在高度上位于同一平面上，这可获得较大的乘坐空间；在纵向(X方向)具有一定的距离，左右车轮的轴距不相等，其不影响乘坐舒适性而获得了扭杆弹簧2的安装空间。一侧车轮的跳动不影响另一侧车轮的运动，该悬架系统获得了独立悬架的车轮运动特性，提高了车轮的跳动行程改善了舒适性。The suspension system is characterized in that the lengths of the two torsion bar springs 2 are equal to the corresponding wheelbases. Specifically, the lengths of the two torsion bar springs 2 are equal, and the distances from the two torsion bar springs 2 to the front axle of the car are different. Such an arrangement can obtain good suspension stiffness, making it have the same riding comfort as the independent suspension of the coil spring; the two torsion bar springs 2 are located on the same plane in height, which can obtain a larger riding space; there is a certain distance in the longitudinal direction (X direction), and the wheelbases of the left and right wheels are not equal, which does not affect the riding comfort and obtains the installation space of the torsion bar spring 2. The bouncing of the wheel on one side does not affect the movement of the wheel on the other side. The suspension system obtains the wheel movement characteristics of the independent suspension, increases the bouncing stroke of the wheel, and improves the comfort.

The same or similar parts between the various embodiments can be referenced to each other.

对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
