Abstract

See full text

A single axle suspension system including right and left dampers, first and second hydraulic circuits, one or more pressurizing mechanisms with a variable volume chamber that is connected in fluid communication with the first or second hydraulic circuits, and a bi-directional pump with a first impeller that is arranged in fluid communication with the first hydraulic circuit, a second impeller that is arranged in fluid communication with the second hydraulic circuit, and a motor that is configured to drive rotation of the first and second impellers to simultaneously pump the hydraulic fluid through the first and second hydraulic circuits in opposite directions. Each pressurizing mechanism includes a driven piston that is moveable in first and second directions to increase and decrease the volume of the variable volume chamber and therefore increase and decrease static pressure within the first and/or second hydraulic circuits independent of damper movements.
