Abstract
A suspension apparatus has suspension units mounted on wheels and each unit has a fluid spring chamber. Fluid is supplied to contracted fluid spring chambers and is exhausted from elongated fluid spring chambers to control the change in position of the vehicle. In the position control mode, a large-diameter path is selected to supply or exhaust a large amount of compressed fluid. In the height control mode, a small-diameter path is selected to supply or exhaust a small amount of compressed fluid. The required amounts of compressed fluid can be supplied to the fluid spring chambers in both the position and height control modes.
