The invention relates to the technical field of automobiles, in particular to an automobile suspension vertical displacement measuring system. Comprising a guide rod and a damping shell, the guide rod enables wheels to move relative to a vehicle body according to a certain motion trail, the axial upper end of the guide rod extends into the damping shell and is in sliding connection with the damping shell, and the damping device further comprises a displacement part and a damping part, a cavity is formed in the damping shell, and the displacement part is arranged in the cavity of the damping shell; comprising a first magnet, a third spring and a gold-palladium alloy lantern ring, the upper end of the guide rod and the first magnet are coaxially fixed, and the gold-palladium alloy lantern ring and the end, away from the guide rod, of the third magnet are coaxially fixed; one end of the third spring is fixed away from one end of the third magnet, and the other end of the third spring is fixed to the extending direction of the guide rod and the inner wall of the damping shell away from the guide rod; the problems that the measurement precision is reduced and the stability is insufficient after the vertical displacement data of the automobile suspension is measured for a long time are solved.

    本发明涉及汽车技术领域,特别涉及汽车悬架垂向位移测量系统。包括导向杆和减震壳体,所述导向杆使车轮按一定运动轨迹相对车身运动,所述导向杆轴向上端部伸入减震壳体,并与减震壳体滑动连接,还包括:位移部:所述减震壳体内部开设有空腔,所述位移部设置于减震壳体的空腔内;包括第一磁铁、第三弹簧和金钯合金套环,所述导向杆上端部与第一磁铁同轴固定,所述金钯合金套环与第三磁铁远离导向杆的一端同轴固定;所述第三弹簧一端钯合金套环远离第三磁铁的一端固定,另一端与导向杆的延伸方向且远离导向杆的减震壳体内壁固定;解决了汽车悬架垂向位移数据长时间测量后,测量精度下降,稳定性不够的问题。
