ABSTRACT:
The invention can take the form of different suspension systems which provide essentially constant force (zero spring rate) individual wheel support of a vehicle during normal individual wheel travel. Zero spring rate is achieved by supplying essentially constant air pressure to air bag suspension elements. In one system regulation of suspension height and air pressure is achieved by open bottom air bags utilizing the ground effects principle. A second system utilizes closed air bags operating against opposing governing springs. Constant air pressure is supplied from a controlled reservoir. Auxiliary force mechanisms are provided for total system support during high vertical, longitudinal and angular vehicle accelerations.
