ABSTRACT:
A level control system for an omnibus, especially a low-loading omnibus, having an omnibus body supported on axles and wheel suspension, is comprised of a compressed air system that is self-contained for each axle. The following vertical adjustments are possible: during a stop of the omnibus at a bus stop, the omnibus body is pivoted about a longitudinal median floor level axis for lowering the omnibus body at a passenger boarding side and the opposite side is raised by internally pumping the compressed air from the pneumatic springs of the boarding side to the pneumatic springs on the opposite side at each axle. After the completion of the stop at the bus stop, the compressed air is returned to the pneumatic springs on the boarding side so that the omnibus resumes its normal position. In this manner, the compressed air is kept in a self-contained system and is not lost to the atmosphere. Accordingly, there is no need to provide further compressed air to the system, thus reducing the amount of energy required for operating such a system; the power necessary for the internal pumping or transfer of the compressed air is small in comparison.
