  • Suspension system
    Patent number: 11945270
    Abstract: A suspension system for a vehicle is provided. A linear regenerative suspension system that converts mechanical energy into storable electrical energy is also provided. The system utilizes pistons, one on each side of the vehicle, engaged with a vehicle body at a distal end and having a fluid chamber at the proximal end. The system further has a central chamber having a rod freely laterally moving therein. A fluid communicates between the central chamber and each piston fluid chamber. Upon nonlinear forces applied to the vehicle, the rod is urged in one direction or another. This urging applies force to the fluid in the central chamber, and in turn, to the piston in the corresponding side of the vehicle, urging the piston up and in turn urging the vehicle body up.
    Type: Grant
