<p>VEHICLE SUSPENSION ARRANGEMENTS A vehicle wheel suspension system includes a suspension device having a double acting hydraulic actuator, of which the piston position and/or 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 the strut pre-load and load deflection characteristics. The fluid body may be a body of oil or of gas, when the volume adjustment, which alteration spring rate, can be effected by alteration of the volume of a liquid directly in contact with the gas body or separated therefrom by a free piston,</p> |
