Abstract
A suspension including a spring interposed between the body (B) of the vehicle and the wheel (W); a regenerative hydraulic shock-absorbing unit comprising a hydraulic shock-absorber arranged parallel to the spring, a motor and pump unit with a volumetric hydraulic machine and an electric machine coupled to the hydraulic machine), and an electronic control unit arranged to control the torque of the electric machine. A hydraulic actuator is arranged in series with the spring. A reservoir and a hydraulic circuit are connected to each other, the hydraulic shock-absorber, the hydraulic machine the hydraulic actuator and the reservoir. The hydraulic circuit includes a valve assembly for controlling the flow of a working fluid between the hydraulic shock-absorber, the hydraulic machine, the hydraulic actuator and the reservoir.
