The invention discloses a suspension type hydraulic shock absorber for an automobile. The suspension type hydraulic shock absorber comprises a shock absorption piston cylinder, a variable-ring-distance spring set and a variable-distance device. The damping piston cylinder comprises a hollow damping cylinder and a piston rod of which the end part is provided with a valve body; the piston rod is sleeved with the damping cylinder and slides up and down along the inner wall of the damping cylinder. The variable-ring-distance spring set is a double-line-distance spring formed by vertically stacking a pair of springs with different ring distances, the variable-ring-distance spring set is sleeved on the periphery of the damping piston cylinder, and the lower end of the variable-ring-distance spring set is fixedly connected with the lower end of the damping piston cylinder. The variable-pitch device is rotationally arranged on the periphery of the upper part of the damping piston cylinder, is rotationally connected with the piston rod and slides up and down along the outer wall of the damping cylinder; the upper portion of the variable-pitch device is rotationally connected with the upper portion of the variable-coil-pitch spring set, when the variable-pitch device rotates by a certain angle, compression of an upper spring of the variable-coil-pitch spring set is limited, and the upper spring is converted into a single-line-pitch spring. The spring of the shock absorber is switched between the equal line distance and the double line distance, the spring is selected according to different road conditions, and a more appropriate shock absorption springback feedback feeling is provided.

    本发明公开了一种用于汽车悬挂式液压减震器,包括减震活塞缸、变圈距弹簧组和变距装置;减震活塞缸包括一个空心的减震筒和一根端部设有阀体的活塞杆;活塞杆套装于减震筒内部,沿减震筒的内壁上下滑动;变圈距弹簧组由一对圈距不同的弹簧上下叠加组成双线距弹簧,套装在减震活塞缸外周,下端与减震活塞缸的下端固定连接;变距装置转动设置于减震活塞缸的上部外周,与活塞杆转动连接,沿减震筒的外壁上下滑动;变距装置的上部与变圈距弹簧组上部转动连接,当变距装置转动一定角度,变圈距弹簧组的上部弹簧压缩受限,转变为单线距弹簧;本发明使减震器弹簧在等线距和双线距之间切换,根据不同的路况条件选择弹簧,提供更为合适的减震回弹回馈感。
