A hydraulic energy recovery and a mechanical drive system in one unit that also provides integral mounting of hydraulic pump/motors for primary drive, secondary drive, and pumps for cooling, lubrication, and low pressure systems along with a mounting position for a power take-off device.

Gear box for hydraulic energy recovery

A combined hybrid drive and brake system for use with a rotatably driven mechanism includes a hybrid drive system that is adapted to decelerate a rotatably driven mechanism, accumulate the energy resulting from such deceleration, and use the accumulated energy to subsequently accelerate the rotatably driven mechanism. A brake system is adapted to decelerate the rotatably driven mechanism. A control apparatus is responsive to a request for braking torque for decelerating the rotatably driven mechanism by either (1) the hybrid drive system operating alone, (2) the brake system operating alone, or (3) both the hybrid drive system and the brake system operating in combination.
