Abstract: A hydraulic suspension apparatus configured to adjust a height of a vehicle body of a vehicle, includes a liquid storage apparatus and a reducer. The liquid storage apparatus is disposed on the vehicle body and configured to store liquid. The reducer has a reducer housing, a piston, and a piston rod. The reducer housing is connected to an axle, and the piston is located in the reducer housing and divides the reducer housing into an upper chamber and a lower chamber. An end of the piston rod is connected to the piston, and the piston rod is connected to the vehicle body and includes a liquid channel. The liquid channel is communicated with the lower chamber and the liquid storage apparatus to enable liquid flowable between the liquid storage apparatus and the lower chamber.

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.
