Hydraulic active suspension and vehicle having hydraulic active suspension

Abstract

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.
