Engine power delivery system with transmission gearing bypass

Abstract:

An engine power delivery system provides bifurcated power-flow with transmission bypass. An engine power delivery system includes an engine that has an output element. A transmission has an input shaft coupled with the engine output element, wherein the engine is configured to generate more power than the transmission is capable of handling. A multi-speed gearing arrangement is included in the transmission and is coupled to the input shaft. An output shaft is coupled with the gearing arrangement and a vehicle axle is coupled with the output shaft to be driven thereby. A generator is configured to be intermittently driven by the engine. A motor is configured to receive electric power from the generator and to drive the vehicle axle without the transmission exceeding the maximum power rating.
