Offset drive system for utility vehicles
First Claim
1. A wheel driven utility vehicle comprising:
- a frame;
a high speed motor having an output shaft with a gear thereon;
an offset planetary gear reducer driven by said output shaft of said gear of said high speed motor and affixed thereto;
said offset planetary gear reducer includes an output carrier interconnected with an output shaft;
said output shaft includes first and second chain drive sprockets;
forward and rearward wheel shafts each having a wheel sprocket;
a first and second chain;
said first chain interengaging said first chain drive sprocket and said forward wheel sprocket driving said forward wheel shaft; and
,said second chain interengaging said second chain drive sprocket and said rearward wheel sprocket driving said rearward wheel shaft.

Abstract
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.
