ABSTRACT:
A power ride shock absorber system for a vehicle suspension, of the strut type mounted between the body and the wheel of the vehicle, including a cylindrical cam and cam followers, the cam followers being forced against the cam to create vertical forces to cancel the rate of the supporting springs over or under the spring forces necessary to support the weight of the vehicle under any conditions. This shock absorber is constructed with a hydraulic cylinder that compensates for variations in the passenger or pay load in the vehicle and to maintain the position of the cam followers on the center of the cam under any and all conditions. This system enables the use of a much higher rated supporting spring that provides much better stability in the vehicle and also provides a much smoother ride. This power ride shock absorber can be installed inside the supporting spring as a strut or can be installed in any available space outside the spring.
