本发明属于一种履带车辆的新型平衡肘，应用于全地形履带车辆，将全地形车辆的履带张紧机构设计在平衡肘上，使其既起到平衡肘本身的悬挂作用，又能起到履带张紧机构的张紧作用。The invention belongs to a new type of balance elbow for crawler vehicles, which is applied to all-terrain crawler vehicles. The track tensioning mechanism of all-terrain vehicles is designed on the balance elbow, so that it not only plays the role of suspension of the balance elbow itself, but also plays the role of The tensioning action of the track tensioning mechanism.
背景技术Background technique
传统的全地形履带车辆平衡肘与扭杆一起构成了履带车辆的悬挂系统，一方面起到支撑车体作用，另一方面起到缓冲地面反力的作用。传统的全地形履带车辆履带张紧机构由履带调整器（机械式或者液压式）、曲臂、诱导轮三部分组成，全地形履带车履带张紧是通过调整履带调整器进而改变曲臂的偏心距来实现。其缺点是结构复杂，质量较大，而且需要拆掉驾驶室或者货箱才能进行履带张紧。The traditional all-terrain tracked vehicle balance elbow and torsion bar together constitute the suspension system of the tracked vehicle, which can support the vehicle body on the one hand and buffer the ground reaction force on the other hand. The traditional all-terrain tracked vehicle track tensioning mechanism consists of three parts: a track adjuster (mechanical or hydraulic), a crank arm, and an inducer. The track tensioning of an all-terrain tracked vehicle is to change the eccentricity of the crank arm by adjusting the track adjuster distance to achieve. The disadvantage is that the structure is complex, the mass is large, and the cab or cargo box needs to be removed to tension the track.
轻量化设计是现代民用装备对全地形履带车辆提出的新要求，以便于长途运输和远程投放。全地形履带车辆通过提高自身燃油经济性，达到减少排放的目的也刻不容缓，同时轻量化本身也能使全地形车辆更好的适应从冰雪覆盖的北极圈到沙漠、沼泽和泥泞丛林等恶劣环境。Lightweight design is a new requirement of modern civilian equipment for all-terrain tracked vehicles, so as to facilitate long-distance transportation and long-distance delivery. It is urgent for all-terrain tracked vehicles to reduce emissions by improving their own fuel economy. At the same time, light weight can also make all-terrain vehicles better adapt to harsh environments ranging from the snow-covered Arctic Circle to deserts, swamps and muddy jungles.

本发明采取技术方案是：花键套筒与平衡肘体焊接，轮毂轴与肘体长螺母固定连接，推力轴承装配到平衡肘体上的孔内，将滑动轴承压装到平衡肘体上的孔内，锁止螺母与螺旋运动副螺杆螺纹连接，肘体长螺母与螺旋运动副螺杆螺纹连接，螺旋运动副螺杆的另一端与滑动轴承内孔间隙配合，减摩垫片装配到紧固法兰的凹槽中，紧固法兰与平衡肘体通过螺栓固定连接。The technical solution adopted by the present invention is: the spline sleeve is welded to the balance elbow body, the hub shaft is fixedly connected to the elbow body long nut, the thrust bearing is assembled into the hole on the balance elbow body, and the sliding bearing is pressed into the balance elbow body. In the hole, the lock nut is threadedly connected with the helical movement sub-screw, the elbow body long nut is threaded with the helical movement sub-screw, the other end of the helical movement sub-screw is matched with the inner hole of the sliding bearing, and the anti-friction gasket is assembled to the fastening method In the groove of the flange, the fastening flange and the balance elbow are fixedly connected by bolts.
本发明所述花键套筒内有扭力轴连接花键槽。The spline sleeve of the present invention has a spline groove for connecting the torsion shaft.
本发明端盖与肘体长螺母上的端孔螺纹连接。The end cover of the present invention is threadedly connected with the end hole on the long nut of the elbow body.
本发明所述轮毂轴与花键套筒是平行的。The hub axle of the present invention is parallel to the spline sleeve.
本发明的优点是：The advantages of the present invention are:
轻量化效果显著，将履带张紧机构设计在平衡肘上可直接去掉原来的由履带调整器（机械式或者液压式）、曲臂、诱导轮总成构成的张紧机构，去掉了4套复杂的履带张紧机构（全地形车辆一般分为前后两节车体，前后两节车体各有两套张紧机构），使行走系统减重近225kg。The weight reduction effect is remarkable. Designing the track tensioning mechanism on the balance elbow can directly remove the original tensioning mechanism consisting of the track adjuster (mechanical or hydraulic), crank arm, and inducer assembly, and remove 4 sets of complicated Unique track tensioning mechanism (all-terrain vehicles are generally divided into front and rear two-section car bodies, each with two sets of tensioning mechanisms), which reduces the weight of the walking system by nearly 225kg.
履带张紧力调整更加便捷，传统的全地形履带车辆，履带张紧机构位于驾驶室或者货箱下部的车体（车架）内部，如果全地形履带车辆发生履带松动，就需要拆掉驾驶室或货箱才能进行履带张紧力调整，费事费力。本发明的履带张紧机构设计在平衡肘上，即位于车体外部，可实现不拆车进行履带张紧力的连续调节。Track tension adjustment is more convenient. For traditional all-terrain tracked vehicles, the track tensioning mechanism is located inside the cab or the car body (frame) below the cargo box. If the tracks of the all-terrain tracked vehicle become loose, the cab needs to be removed. Or cargo box just can carry out track tension adjustment, laborious and laborious. The track tensioning mechanism of the present invention is designed on the balance elbow, that is, located outside the car body, and can realize continuous adjustment of the track tension without dismantling the car.
使全地形履带车辆结构更加紧凑，新型的带有张紧机构的全地形车平衡肘，将履带车俩的张紧机构设计在平衡肘上，既起到了平衡肘的悬挂作用，又起到履带张紧机构作用，结构更加简单、紧凑合理。To make the structure of the all-terrain tracked vehicle more compact, the new type of all-terrain vehicle balance elbow with a tensioning mechanism, the tension mechanism of the tracked vehicle is designed on the balance elbow, which not only plays the role of suspension of the balance elbow, but also plays the role of track The tension mechanism works, and the structure is simpler, compact and reasonable.
考虑到全地形履带车辆履带张紧力较大，故在螺旋运动副螺杆一侧设计了推力轴承、滑动轴承、减摩垫片，这样不仅可以在不拆车的情况下进行履带张紧，而且能够满足履带张紧力较大的要求；考虑到全地形履带车辆实际行驶路况较为恶劣，平衡肘时刻承受冲击载荷，故在螺旋运动副上设计了锁止螺母，防止车辆行驶过程中履带松脱，以及主动轮打齿破坏。Considering that the track tension force of the all-terrain tracked vehicle is relatively large, thrust bearings, sliding bearings, and anti-friction pads are designed on the side of the helical motion sub-screw, so that not only can the track be tensioned without dismantling the vehicle, but also It can meet the requirements of large track tension; considering that the actual driving conditions of all-terrain tracked vehicles are relatively harsh, and the balance elbow is always subjected to impact loads, so a lock nut is designed on the screw kinematic pair to prevent the track from loosening during vehicle driving , and the toothing damage of the driving wheel.
车体空间增大。去掉原来的履带张紧机构，车体内部空间增大，前车体内部空间增大使发动机和变速器的安装布局更加合理，并且使液压管路和高压线缆布置更加顺畅；后车体内部空间增大，可以增大全地形履带车辆的燃油储备，增加续航里程。The body space is increased. The original crawler tensioning mechanism is removed, and the internal space of the car body is increased. The increased internal space of the front car body makes the installation layout of the engine and transmission more reasonable, and makes the layout of hydraulic pipelines and high-voltage cables smoother; the inner space of the rear car body increases. Large, can increase the fuel reserve of the all-terrain crawler vehicle and increase the cruising range.
节约研发试验成本，从设计加工角度考虑，可以去掉张紧机构组别的设计及工艺人员，节约可观的人力成本；从维护保养维修角度考虑，由于张紧机构设计在平衡肘上面，在不拆车的情况下即可维护保养或者维修，在整车试验环节上节约了较多资源和成本。Save R&D and test costs. From the perspective of design and processing, the design and technical personnel of the tensioning mechanism group can be removed, saving considerable labor costs; from the perspective of maintenance and repair, since the tensioning mechanism is designed on the balance elbow, it can be used without dismantling. It can be maintained or repaired without the vehicle, saving more resources and costs in the vehicle test process.
