The invention relates to the technical field of automobile chassis manufacturing, in particular to a vehicle body and chassis connection damping device which comprises a vehicle body supporting plate, a chassis supporting beam and connecting bolts, the vehicle body supporting plate is used for being fixedly connected with a vehicle body bottom plate framework, the chassis supporting beam is used for being fixedly connected with a chassis frame, and the chassis supporting beam comprises two bracket frames; the two bracket frames are symmetrically and fixedly arranged on a chassis frame, damping mechanisms are arranged in the two bracket frames, each damping mechanism comprises a first guide column, and the top end of each first guide column penetrates through the top wall of the corresponding bracket frame and is fixedly connected with the end of the vehicle body supporting plate through the corresponding connecting bolt; bolt limiting structures are arranged at the two ends of the vehicle body supporting plate correspondingly and used for limiting and fixing the connecting bolts to the ends of the vehicle body supporting plate. The damping device is good in damping effect and high in stability through the damping mechanism; and through a bolt limiting structure, the connecting bolt does not have the risk of loosening or even falling off.

    本发明涉及汽车底盘制造技术领域,具体涉及一种车身与底盘连接减震装置,包括车身托板、底盘托梁以及连接螺栓,所述车身托板用于与车身底板骨架固定连接,所述底盘托梁用于与底盘车架固定连接,所述底盘托梁包括两个托架框,两个所述托架框对称固定设置于底盘车架上,两个所述托架框内均设置有减震机构,所述减震机构包括第一导向柱,所述第一导向柱顶端穿过所述托架框顶壁与所述车身托板端部通过所述连接螺栓固定连接,所述车身托板两端分别设置有螺栓限位结构,所述螺栓限位结构用于将所述连接螺栓限位固定在所述车身托板端部。上述减震装置通过减震机构实现减震效果好,稳定性强;通过螺栓限位结构,使连接螺栓不存在松动甚至脱落的风险。
