Abstract
A vehicle roll control system, comprising a front torsion bar(22), attached to the front hydraulic actuator (34) and a rear torsion bar (24) attached to the rear hydraulic actuator (34'). A pressure control valve (99) is fluidly connected between a pressure source (80) and a reservoir (81). A directional valve (82) is fluidly connected between the pressure control valve (99) and the hydraulic actuators (34,34'). A pressure relief valve (83,84) fluidly connects the directional valve to the pressure source (80) or the reservoir (81) and is actuated to create pressure differential between first fluid chambers (58,58') of the hydraulic actuators (34,34')and/or to create pressure differential between second fluid chambers (60,60') of the hydraulic actuators (34,34').
