ABSTRACT:
A method and apparatus for a low-profile suspension system, which provides coarse and fine suspension control to an object supported by the low-profile suspension system. Coarse suspension is provided to adaptively control a position of the object through pneumatic support devices. Pneumatic pressure is adaptively increased in the pneumatic support devices to support an increasing weight of the object, while pneumatic pressure is adaptively decreased in the pneumatic support devices to support a decreasing weight of the object. Fine suspension control is provided through rotational actuation of a shock absorbing device through a right-angle gear drive. By rotationally actuating the shock absorbing device, a range of stroke of the shock absorbing device along a vertical direction is minimized. Position equalization control is further provided to maintain a position of the object along an axis that is orthogonal to the coarse and fine suspension axis.
