<p>A method of controlling ride height of a vehicle having hydro-pneumatic suspension by adjusting volume and/or pressure of an active volume of gas within at least one accumulator 26. Another form of the invention is a hydraulic suspension system for a vehicle including a body and at least one forward pair of laterally spaced wheels and at least one rearward pair of laterally spaced wheels. The system includes at least one wheel ram 101-110 for at least one laterally spaced pair of wheels to provide substantially all the support of the load on the laterally spaced wheels. The wheel ram(s) include(s) at least a compression chamber (eg 201-207), at least one accumulator (eg 261,263,265,268) including a liquid chamber and a gas chamber separated by a moveable wall. The liquid chamber forms a liquid volume connected to a compression chamber of at least one wheel ram forming a wheel ram compression volume. The gas chamber forms an active gas volume. Gas is supplied to and released from the active gas volume to adjust the quantity of gas in the active gas volume to compensate for load changes on the vehicle or on at least one said pair of laterally spaced wheels.</p> |
