ABSTRACT:
A vehicle suspension system is provided for tilting a chassis 24 with respect to the axes of vehicle wheels 31 and 32 during cornering to improve the comfort of travel for occupants of the vehicle. A lateral or centrifugal force sensor mounted to the chassis 24 provides a control for a hydraulic pump to cause a piston 15 in a cylinder 14 to move to the left or right. The Figure shows the piston 15 to the left of a mean central position and its movement has caused the chassis to tip to the right. The vehicle in the Figure is shown moving away and to the right. For the corner, the tilt is stable as the sensor will remain balanced, that is not then generating further or extra tilting, until the degree of cornering changes or the vehicle straightens out. In the latter case, the sensor will respond to cause the piston 15 to move to its central position and the chassis to level off.
