Abstract

A hydropneumatic suspension system consists of plural separate individual wheel suspension units, one for each wheel, whereby should damage occur to any one of the units, it will not affect the operation of the other units. The heat generated by each individual wheel suspension unit is kept to a minimum, and the heat that is generated is dissipated through the vehicle hull by locating the valving and fluid passageways in close proximity to the hull. Increased heat dissipation may also be obtained by providing an air cooled tube in the fluid path between the actuator and accumulator, and by providing a flow path for the return fluid from the accumulator to the actuator in the unit mounting flange which is bolted or otherwise secured in close mating engagement with a large surface area of the vehicle hull.
