Abstract

A vehicle wheel suspension system includes a suspension device having a double acting hydraulic actuator, of which the piston position is adjustable in response to forces acting on the piston and/or to a selective control input, and a load bearing strut operable in response to the actuator piston experience to minimize the actuator load. The device comprises an inner member having a portion slidable within an outer member with the piston on the inner member and slidably engaging the outer member and a fluid body operative between the members, the volume of which is selectively adjustable to alter and strut pre-load and load deflection characteristics. The fluid body may be a body of oil or a gas.
