Title: Vehicle hydropneumatic damped suspension - with two stage damping controlled by differential pressure across axle for hard rolling damping
Inventor: STRAUFF GUENTHER ING GRAD
IPC: B60G21/06
Filed: 1975-12-24
Abstract: The hydropneumatic suspension has the hydraulic control lines linked to a flow control valve on each axil to control the flow of fluid between the reservoir and the suspension element. During cornering, inertial sensors block the connecting line between the elements on each axle to allow for roll compensation. The supply line between the reservoir and the elements has a two stage flow control piston, with a differential piston, controlled by the differential pressures across the axle. For similar pressures, such as normal travel, the flow restriction is at full flow, to give a soft ride. When the differential pressure exceeds a set amount, i.e. the vehicle is cornering, then the flow restriction is at a minimum flow setting for a hard suspension.
