A vehicle fluid spring system is adapted to absorb road shock imparted onto at least one road wheel of a vehicle. The vehicle fluid spring system includes a fluid spring and a variable volume unit. The fluid spring includes a fluid chamber adapted to change in volume. The variable volume unit including a rigid piston cylinder, a piston, a fluid cavity, and an actuator. The piston is adapted to reciprocate within, and is in sliding contact with, the rigid piston cylinder. The fluid cavity is defined by the piston cylinder and the piston. The actuator is adapted to drive the piston changing a volume of the fluid cavity. The fluid cavity is in fluid communication with the fluid chamber.

一种车辆流体弹簧系统适于吸收施加到车辆的至少一个车轮上的道路冲击。车辆流体弹簧系统包括流体弹簧和可变容积单元。流体弹簧包括适于改变容积的流体室。可变容积单元包括刚性活塞缸、活塞、流体腔和致动器。活塞适于在刚性活塞缸内往复运动并与其滑动接触。流体腔由活塞缸和活塞限定。致动器适于驱动活塞以改变流体腔的容积。流体腔与流体室流体连通。
