The present invention is a system and method for recovering the kinetic energy created by movement of a vehicle frame relative to a vehicle suspension to generate electrical energy that may be utilized on-the-fly or stored in order to provide power to an electric vehicle, wherein an embodiment for a regenerative energy system uses a plurality of gear assemblies to convert linear up-and-down movement of the vehicle to rotary motion that is then amplified in rotational speed by a gear reduction system to cause rotational movement of a shaft of one or more generators in a single rotational direction to thereby generate electricity that may be utilized directly by electrical motors or stored in batteries or supercapacitors.

A torque amplification device for amplifying torque of a power transmission shaft and transmitting the amplified torque to a driven shaft according to an embodiment includes one or more eccentric amplification parts including a first rotation part, to the center portion of which a shaft in the power transmission shaft direction is connected and which is eccentrically connected to a shaft facing the driven shaft in a driven shaft direction; and an output end amplification part which is connected to the eccentric amplification part through a rotary shaft in the power transmission shaft direction, includes a second rotation part connected to the outside of the rotary shaft, and transmits the torque of the rotary shaft, transmitted from the eccentric amplification part, to one side of the second rotation part so as to drive same, thereby transmitting the torque of the second rotation part in the driven shaft direction.

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 apparatus can be used as an actuator to create linear movement. Applications include vehicle suspension systems (to act as the primary damper component), railcar bogie dampers, or industrial applications such as machinery dampers and wave energy harvesters, and electro-hydraulic actuators.
