<p>A vehicle suspension system has a gas-sprung hydraulic strut (6,7) for each of its four wheels (2,3). Each liquid actuator chamber (8) of the struts (6) at one end of the vehicle is connected (9) to a further chamber (10) in the diagonally opposite strut (7), which further chamber (10) acts in the opposite direction to the actuator chamber (13) of that strut (7). A linear potentiometer (26) within each strut (6,7) provides a signal representative of the strut length to an on-board computer (28), which, when it detects a difference in the signal from any strut sensor (26) from a predetermined value, causes a proportional servo-valve (35) to admit hydraulic liquid from the actuator chamber of that strut at a flow rate proportional to the detected difference to return the strut length towards its predetermined value.</p> |
