The invention relates to a hydraulic damper, a shock absorber and a vehicle. The hydraulic damper comprises a cylinder body; the piston group comprises a first piston and a second piston which are accommodated in the cylinder body and are axially arranged at an interval, gas is filled between the first piston and the second piston, and the piston group divides the cylinder body into a first space and a second space which are respectively filled with damping liquid; the piston rod comprises a head part and a rod part, the head part is accommodated in the first space, the peripheral surface of the head part abuts against the inner wall of the cylinder body, and the rod part penetrates out of the cylinder body from the first space; and the pumping system comprises a liquid storage barrel arranged outside the cylinder body, and the liquid storage barrel is in fluid communication with the second space, so that the liquid storage barrel sucks the damping liquid from the second space or discharges the damping liquid into the second space. As the damping process and the lifting process share the same oil cylinder, a lifting oil cavity does not need to be independently arranged, the size of the lower end of the hydraulic damper can be reduced, and arrangement and installation of the damper are facilitated.
本公开涉及一种液压阻尼器、减振器和车辆,液压阻尼器包括:缸体;活塞组,包括容纳在缸体中且轴向间隔设置的第一活塞和第二活塞,第一活塞和第二活塞之间填充有气体,活塞组将缸体分隔为分别填充有阻尼液的第一空间和第二空间;活塞杆,包括容纳在第一空间中且外周面抵顶到缸体的内壁的头部,和从第一空间穿出到缸体的外部的杆部;以及泵送系统,包括设置在缸体的外部的储液筒,储液筒与第二空间流体连通,以使储液筒从第二空间中吸取阻尼液,或将阻尼液排到第二空间中。由于阻尼消振过程和升降过程共用同一个油缸,无需单独设置升降油腔,可减小液压阻尼器下端尺寸,利于阻尼器布置安装。
