Abstract

See full text

A dual-circuit hydraulic system for an active vehicle suspension control system to eliminate a rolling movement of a motor vehicle by using an adjustable stabilizer on a motor vehicle front axle and an adjustable stabilizer on a motor vehicle rear axle. The dual-circuit hydraulic system has at least one supply pump which uses at least one shuttle valve to supply a pressure medium, by way of supply lines, to at least one dual action actuator on each stabilizer. Each dual action actuator has at least two working chambers. In emergency operation of the shuttle valve, the working chambers of the at least one actuator on the rear axle are unblocked, so that in the event of a rolling movement of the vehicle, the pressure medium is transferred by being pushed out of the working chambers of the rear axle actuator by the action of the rolling movement of the vehicle on the rear axle stabilizer.
