Abstract
A suspension system for a vehicle having left and right wheels is disclosed and claimed. The system includes first and second suspension struts and first and second hydraulic cavities to supply first and second suspending spring force for the left and right wheels, respectively. The system also includes a volume modulator to selectively push fluid into and vent fluid from the first and second hydraulic cavities, thereby actively modulating the first and second suspending spring forces. The volume modulator includes first and second modulator pistons and first and second cavity-side valves. In a preferred embodiment, the modulator pistons are cycled and the cavity-side valves are opened and closed to counteract roll of the vehicle. Further, in a preferred embodiment, the first modulator piston and the second modulator piston are located approximately 180° apart relative to an eccentric to minimize power consumption of the volume modulator during roll of the vehicle.
