ABSTRACT:
A multiple power path concentric speed reducer in which a center shaft having a pinion thereon and an axle having an externally toothed gear thereon are disposed coaxially with respect to one another, and a plurality of gear trains operatively connect the pinion with the gear to provide multiple power path between the pinion and gear. The power or load is distributed equally between the several gear trains, and the center shaft may be the power input member, a housing the power output member and the axle the reaction member; or the center shaft may be the power input member, the axle the power output member, and the housing the reaction member. The concentric speed reducer is particularly adapted for use in vehicle wheel drives, especially in off-the-highway heavy duty equipment, wherein the speed reducer for each wheel is driven by a separate motor, such as a DC motor, mounted in or on the axle of the respective wheel.
