VEHICLE SUSPENSION SYSTEM WITH MULTIPLE MODES OF OPERATION

Abstract: a suspension system including four dampers is disclosed where each damper includes a compression chamber and a rebound chamber. first and second hydraulic circuits interconnect the compression and rebound chambers of the front left and back right dampers, while third and fourth hydraulic circuits interconnect the compression and rebound chambers of the front right and back left dampers. a first bi-directional pump is connected between the first and second hydraulic circuits and a second bi-directional pump is connected between the third and fourth hydraulic circuits. the first and second bi-directional pumps can either pump in the same direction or in opposite directions. the level of pitch and roll stiffness can be adjusted by running the first and second bi-directional pumps to change the pressure in select hydraulic circuits of the system.
