SUSPENSION PROCESS AND APPARATUS OF THE TYPE HAVING DIFFERENT STIFFNESSES WITH PROVISION TO SMOOTH THE CHANGE FROM ONE STIFFNESS TO ANOTHER

摘要

A suspension for the wheels of a motor vehicle, the suspension having an operating load position in which the suspension is deformed by a force equal to the weight of the vehicle, a suspended wheel position in which the suspension is deformed by a force less than the weight of the vehicle and a collapsed position in which the suspension is deformed by a force greater than the weight of the vehicle. The suspension has a stiffness that is greater between the operating load position and the suspended wheels position than between the operating load position and the collapsed position. A gradual transition is provided between these stiffnesses.
