Abstract: Buses would be advantaged - both as to passenger comfort and to vehicle maintenance and longevity - by a suspension system operating at or near zero rate as affecting the sprung mass. At the same time, such a system should be able to provide precise ride height and roll squat and dive-resisting forces at each wheel without reference to support forces at other wheels and at the same time with only indirectly related control of the unsprung masses by re-ingestion. Fully-active and semi-active suspension systems are described to achieve these objectives by all-hydraulic means.

Keywords: buses; hydraulic struts; bus design; hydraulics; passenger comfort; active suspension; vehicle design; semi-active suspension.
