    摘要: A hydraulic active suspension for a vehicle includes: a shock absorber, a common channel, an accumulator module, and a liquid storage apparatus. The shock absorber has a housing, a piston, and a piston rod. The housing is adapted to be connected to a wheel or an axle. The piston is located in the housing and defines an upper chamber and a lower chamber of the shock absorber. One end of the piston rod is connected to the piston. The other end of the piston rod projects out of the housing and is adapted to be connected to a body. Both the liquid storage apparatus and the accumulator module are in communication with the lower chamber through the common channel. The liquid storage apparatus is configured to adjust a height of the vehicle. The accumulator module is configured to adjust at least one of stiffness and damping of the shock absorber.

    摘要: A damper with a pressure tube and an outer tube, a piston rod extending between first and second piston rod ends, and a piston mounted to the second piston rod end. The piston is disposed within the pressure tube to define rebound and compression chambers. A reservoir chamber is positioned between the pressure tube and the outer tube and an intake valve assembly, abutting one end of the pressure tube inside the outer tube, defines at least one intermediate chamber that is arranged in fluid communication with at least one externally mounted, electro-mechanical control valve. A rebound chamber pressure relief valve, in the form of a poppet positioned inside the piston and piston rod end, releases excess fluid pressure in the rebound chamber. A compression chamber pressure relief valve, in the form of a poppet positioned inside the intake valve assembly, releases excess fluid pressure in the compression chamber.
