The “Electrogear” — A new electromechanical vehicle drive

Within recent years a new electromechanical transmission known as the “Electrogear” has been developed for use in gas and Diesel engine cars of all types including busses, trucks, rail cars, and track-laying vehicles. The paper describes the principle of its operation which is basically a differential action between direct mechanical power transmission and a generator-motor system, interlinked by means of a permanently engaged planetary differential gear.
