Vehicle shock absorber system comprises passive spring and parallel hydraulic shock absorber, pressure line feeding hydraulic fluid to shock absorber and control unit altering its pressure

摘要

The shock absorber system for a vehicle comprises a passive spring (2) and a hydraulic shock absorber (3) which is parallel to it. A pressure line (13) feeds hydraulic fluid from a tank (21) to the shock absorber. A control unit (17) alters the pressure in the shock absorber, using signals based on speed of the car, rpm of the wheels, gear ratio or transverse acceleration.
