PROBLEM TO BE SOLVED: To provide a vehicle suspension hydraulic bush controlling system which improves vibration insulation, running stability and turning stability at a high speed. SOLUTION: This system is constituted by an outer cylinder joined to a lower arm 4, an inner cylinder joined to a car body 10, an elastic body provided between the outer cylinder and the inner cylinder, an elastic body housing, two hydraulic rooms, an elastic body pin, a hydraulic pitting, and a sealing projection. A suspension system for supplying hydraulic pressure to each hydraulic room of a hydraulic bush 40 is constituted by an oil tank, a hydraulic pump 62, a motor for driving the hydraulic pump, a car speed sensor 71, a steering angle sensor 72, a pressure control valve for supplying or discharging pressure to or from the hydraulic rooms of the hydraulic bush, an electronic controller 7 for sending an electric signal to the pressure control valve and the motor, and a relief valve 64 for setting a system pressure. This makes the elastic body easily contract or expand and prevents an oil leak by the elastic body and a breakage by an external pressure. |
