The invention discloses a vacuum boosting supporting type damping and buffering device for a vehicle, and belongs to the technical field of vehicle anti-collision device installation. The vehicle limiting mechanism is used for limiting wheels and a vehicle body of a rear vehicle; the primary buffer mechanism is connected with the vehicle limiting mechanism; one end of the second-stage buffering mechanism is connected with the first-stage buffering mechanism, the other end of the second-stage buffering mechanism is used for being connected with the tail of the operation vehicle, and the vehicle limiting mechanism and the second-stage buffering mechanism are arranged at the two ends of the first-stage buffering mechanism correspondingly. The device has four buffering processes, namely a self-telescopic hydraulic wheel limiting process, an automatic capturing vehicle body limiting process, a rack type first-stage damping buffering process and an air assistance type second-stage damping buffering process, buffering force can be increased to the maximum degree to offset collision force when two vehicles collide with each other, it is ensured that the operation vehicle is not damaged after being collided, and the service life of the operation vehicle is prolonged. And meanwhile, the impact force borne by the rear vehicle is reduced as much as possible, so that the personal safety of passengers in the rear vehicle is ensured, and the maintenance cost of the rear vehicle is reduced.

    本发明公开了一种车用真空助力支撑型减震缓冲装置,属于车辆防撞装置安装技术领域。其包括:车辆限位机构,其用于对后车的车轮与车身进行限位;一级缓冲机构,其与车辆限位机构连接;二级缓冲机构,其一端与一级缓冲机构连接且另一端用于与作业车车尾连接,车辆限位机构与二级缓冲机构分别设置在一级缓冲机构的两端。本装置具有四个缓冲过程,分别为自伸缩液压车轮限位过程、自动捕捉车身限位过程、齿条型一级减震缓冲过程、空气助力型二级减震缓冲过程,可在两车碰撞时最大程度地增加缓冲力以抵消碰撞力,确保作业车受撞后无损,同时也尽可能地减少了后车受到的冲撞力,进而确保后车乘坐人员的人身安全,以及减少后车的维修成本。
