VEHICLE WHEEL SUSPENSIONS USING A SPRING COMBINED WITH A FLEXIBLE ARMORING ADAPTED TO MODIFY ITS STIFFNESS CURVE

摘要

The invention screw spring 52 and the flexible support and the inflection when in connection Amorim that, the operation relating to a vehicle wheel suspension (51) state using a 53 point obtained two different stiffness curve in the working position by maintaining the spring in a compressed state is added to a portion of a stress to the spring; Assembly 52 of the helical spring in compression for such location is on the other hand to be compressed, only the portion that is not subjected to the stress of the expansion when the spring 52 is under reduced pressure, and thus the suspension is when a larger expansion than the rigidity at the time of compression stiffness due and the asymmetry, each Amorim the one hand, two flexible made of elements, one of which (54) is operating at least a portion the cross-winding of the screw spring 52, and another one (56) interacts with the body of the spring 52, the remaining windings in whole or in part, and co-operate or shock absorber (59) of, and the Amorim on the other hand, the deformable and expands upon compression is made to a non-deformed longitudinal element 55, the longitudinal element being fixed to the two fixed and the support element, Amorim 53 when two or more of the apex of the spring 52 Surrounding at least a part exerts a stress.
