Gear reducer electric motor assembly with internal brake
A compact gear reducer electric motor assembly with an internal brake disclosed and claimed wherein a high speed electric motor is interconnected with a gear reducer having substantial gear reduction. The assembly includes a spindle, a brake mounted substantially within said high speed electric motor and operable against a spring biasing said brake into engagement with ground. The brake is electrically actuated to permit transmission of energy to the gear reducer. The gear reducer includes an input, intermediate and output planetary stages. The input and intermediate stages residing within the spindle, and, the output planetary stage drives an output ring gear. Releasing means for releasing the output ring gear from the brake allowing rotation thereof.
A bearing lubrication device in a right angle gear reducer includes a gear housing having an interior portion and a lubricating fluid reservoir therein. An oil slinger, rotating pinion shaft, pinion shaft housing, and bearings for supporting the pinion shaft within the pinion shaft housing work together to provide a continuous supply of oil to the bearings. The pinion shaft includes two radially and longitudinally extending passageways therethrough which supply oil from a recess in one end of the pinion shaft to the bearings. Oil is slung from the reservoir into the recess of the rotating pinion shaft where it is forced outwardly and through the passageways to a chamber formed by the rotating pinion shaft, shaft housing and bearings. The roller bearings pump the oil from the chamber back to the fluid reservoir. Oil passageways in the shaft housing enable the return of oil from one bearing set.

A wheel driven utility vehicle includes a frame and two small volume high speed alternating current electric motors arranged side by side for driving the vehicle. Alternatively high speed direct current, hydraulic or pneumatic direct current motors may be used with suitable controls. Each motor has an output shaft which drives an offset planetary gear reducer. Each offset planetary gear reducer is affixed to the electric motor and includes an output carrier interconnected with an output shaft. Each output shaft includes first and second chain drive sprockets which drive chains interconnected with shafts driving the front and rear wheels respectively. Each offset planetary gear reducer enables use of space saving high speed relatively low-torque alternating current electric motors with attendant large speed reductions. Gear reduction enables the production of sufficient torque at the wheels of the vehicle. Applications in addition to utility vehicles are also specifically contemplated.
