A suspension system consists of springs, shock absorber, axles, rods and ball joints. is controlled by the control unit with the electric converter, Reference  presented an oleo-pneumatic actuator, applied to a low-bandwidth active suspension and the, system are also described. Independent suspension system. It consisted solely of a fixed continuous member extending across the entire front end of the vehicle connecting the two steerable wheels. In these applications, the combination of low voltage (typically 12 V) and high force levels, inevitably gives rise to very demanding actuator designs. The organization and arrangement of irrelated or distributed elements in a system or an object is defined as mechanical structure. Indeed, the suspension's motors may be regarded as the world's strongest quadraphonic speakers, even though they hardly make a sound.
