Abstract:
1. A vehicle suspension system for use on road and off road placed between a chassis for autos, sport utility vehicles or trucks having a sprung weight and each of a plurality of wheel axle supports carrying unsprung weight, the vehicle suspension system at least operative to independently control motion between the chassis and each wheel axle support during jounce and rebound, the vehicle suspension system including a plurality of load springs having an elastic constant, each load spring located between the chassis and its respective wheel axle support, each of the plurality of respective load springs for supporting the sprung weight of the chassis carried there on at a ride height relative to its respective wheel axle support and for substantially carrying the sprung weight during jounce motion of the chassis, each of the respective load springs mounted to the chassis for flexing between the chassis and its respective wheel axle support for resisting motion of the chassis sprung weight under load and during jounce, the vehicle suspension system for road travel comprising: a rebound control spring for rebound control resulting from vehicle transients or road conditions mounted to the chassis and each wheel axle support for exerting increasing force to its respective wheel axle support during rebound motion of the sprung weight of the chassis away from its respective wheel axle support, each rebound control spring operatively mounted in opposition to its respective load spring for increasing resistance to chassis sprung weight rebound motion and to initiate the application of resistance to rebound motion of the chassis by transfer of the unsprung weight of each respective wheel axle support through each rebound control spring to the chassis upon motion of the sprung weight away from its respective wheel axle support, the rebound control spring is elastic to stretch sufficiently between the chassis and its wheel axle support even when the load spring is compressed to its maximum load capacity, each respective rebound control spring mounted to oppose the jounce motion of the load spring to provide a transition between the end of jounce motion and the beginning of rebound motion as the rebound motion of the chassis sprung weight caused by reaction to road surface, cornering and braking is resisted by its respective wheel axle support.
