Abstract
A hydraulic regenerative braking system is provided for using hydraulic fluid to capture energy from a vehicle during a braking event. The system captures kinetic energy from a shaft of the vehicle and stores the kinetic energy as hydraulic potential energy. That is, the system captures rotational energy as hydraulic potential energy in an accumulator. The hydraulic regenerative braking system also discharges the hydraulic potential energy as kinetic energy. During braking, kinetic energy is transferred from the vehicle shaft to a gearbox, and from the gearbox to a hydraulic pump. The hydraulic pump uses the kinetic energy to pump hydraulic fluid to an accumulator, increasing the hydraulic potential energy stored in the accumulator. During driving, the hydraulic fluid is released from the accumulator to the hydraulic pump, generating kinetic energy that is transferred to the vehicle shaft via the gearbox.
