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.

Abstract: A hydraulic integrated control module includes: an integrated base, a liquid reservoir, a control valve, and an accumulator module. The integrated base is provided with an oil channel. An outer peripheral wall of the integrated base is provided with an external connection port connected to the oil channel, and the external connection port is configured to connect to the shock absorber. The liquid reservoir is arranged on the integrated base, and the liquid reservoir is connected to the oil channel. The control valve is connected in series in the oil channel to control connection or disconnection of the oil channel. The accumulator module is arranged on the integrated base, and is connected to the oil channel. The accumulator module is configured to adjust an amount of oil in the oil channel.

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 connecting device for connecting a vehicle sub-frame and a vehicle body and a vehicle comprising the connecting device are also provided. The connecting device comprises a first end adapted to be fastened onto the vehicle sub-frame, and a second end adapted to be fastened onto the vehicle body, and the second end has at least one first branch adapted to be fastened onto a side member of the vehicle body and at least one second branch adapted to be fastened onto a bottom floor of the vehicle body.
