ABSTRACT:
A vehicle having a load support body, and a pair of front ground engaging wheels and a pair of rear ground engaging wheels connected to the body to support the body is shown, with each wheel being displaceable relative to the body in a generally vertical direction. A double acting fluid ram has a piston and is interconnected between each wheel and the body. Each ram includes a first and second fluid filled chamber on opposite sides of the ram piston, with the first and second chambers varying in volume in response to vertical movement between the respective wheel and the body. First conduits provide fluid communication between the first chambers of the front and rear rams on the same side of the vehicle, and second fluid conduits provide communication between the second chambers of the front and rear rams on the same side of the vehicle. A first further fluid communicating conduit interconnects the first fluid conduit on each side of the vehicle to the respective second fluid conduit on the opposite side of the vehicle, to thereby provide two fluid circuits, each including one of the first conduits, one of the second conduits, and one of the first further conduits interconnecting the first and second conduits. Each circuit is adapted to resiliently vary the fluid capacity of the circuit by an accumulator to accommodate fluid displaced from rams in that circuit with a resultant pressure rise in the circuit.
