PROBLEM TO BE SOLVED: To provide an energy-generating device that captures energy associated with relative motion, whilst providing damping to movement in a compact, self-contained apparatus, offering the ability to be a direct replacement for non-energy harvesting dampers.SOLUTION: A linear energy harvesting device that includes a housing and a piston that moves at least partially through the housing when it is compressed or extended from a rest position. When the piston moves, hydraulic fluid is pressurized and drives a hydraulic motor. The hydraulic motor drives an electric generator that produces electricity. Both the motor and generator are central to the device housing. Exemplary configurations are disclosed such as monotube, twin-tube, tri-tube and rotary based designs that each incorporates an integrated energy harvesting apparatus. By varying the electrical characteristics on an internal generator, the kinematic characteristics of the energy harvesting apparatus can be dynamically altered. In another mode, the device can be used as an actuator to create linear movement. |
