Hydromechanical control system

Abstract

A hydromechanical pressure control system includes a dual pump and cam assembly, which operates in association with an orifice and a relief valve to develop a pressure for operating a multiple disk friction damper. In one embodiment, the friction damper is associated with a torsion bar for spring supporting a vehicle hull on a road arm, which has a spindle for connection to a road wheel, and the cam is configured to operate two pumps to produce a pressure on the friction damper for damping of both jounce and rebound movements of the road wheel relative to the hull, independently of the relative position of the hull and the road wheel during terrain induced movements of the vehicle and its road wheels and wherein a snubber and the torsion bar system improve the energy absorption and energy storage characteristics of the suspension system to thereby improve the ride quality and handling characteristics of said vehicle and to reduce energy requirements when operating off-road.
