The invention provides a hydraulic lifting actuator for adjusting the height of a vehicle and a height adjusting system. A hydraulic lift actuator for adjusting the height of a vehicle includes: a top mounting plate configured for attachment to a chassis element; a hydraulic cylinder having a tubular wall and an end cap, the tubular wall and the end cap together defining an internal chamber; the piston rod axially extends into the inner cavity; the piston assembly is connected to the piston rod and arranged in the inner cavity, the piston assembly divides the inner cavity into an upper cavity and a lower cavity, and the lower cavity extends between the piston assembly and the end cover; and a spring seat rigidly connected to the hydraulic cylinder and configured to engage an upper end of the coil spring, where the spring seat and the hydraulic cylinder are linearly translatable relative to the piston rod between a retracted position adjacent the top mounting plate and an extended position spaced apart from the top mounting plate.
本公开提供了一种用于调整车辆的高度的液压提升致动器及高度调整系统。一种用于调整车辆的高度的液压提升致动器包括:顶部安装板,其被配置用于附接到底盘元件;液压缸,其具有管状壁和端盖,管状壁和端盖一起限定了内部腔室;活塞杆,其轴向延伸到内部腔室中;活塞组件,活塞组件连接到活塞杆并且设置在内部腔室内,其中,活塞组件将内部腔室分成上腔室和下腔室,下腔室在活塞组件与端盖之间延伸;以及弹簧座,其刚性地连接到液压缸并且被配置为接合螺旋弹簧的上端,其中,弹簧座和液压缸可相对于活塞杆在邻近顶部安装板的缩回位置和与顶部安装板间隔开的延伸位置之间线性平移。
