Engine power delivery system with transmission gearing bypass

An engine power delivery system comprising:

• an engine driving a first shaft;
• a transmission coupled with the first shaft;
• a gearing arrangement in the transmission configured to be driven by the first shaft, and configured to produce multiple speed ratios;
• a second shaft coupled with the gearing arrangement and configured to be driven at a variety of output ratios relative to the first shaft;
• a vehicle axle coupled with the second shaft and configured to be driven thereby;
• a third shaft configured to be driven directly by the first shaft at a common speed therewith;
• a generator configured to be intermittently driven to generate electric power by the third shaft;
• and
• a motor electrically coupled with the generator and configured to receive electric power from the generator to drive the vehicle axle.

A power delivery system for a work vehicle comprising:

• an internal combustion engine;
• a first propulsion shaft configured to be driven by the engine;
• a transmission having a transmission housing and an input shaft coupled with the first propulsion shaft, the input shaft extending into the housing;
• a gearing arrangement configured to deliver multiple speed ratios and disposed in the transmission housing, the gearing arrangement coupled with the input shaft within the transmission housing;
• a front axle configured to be driven by the engine through the transmission;
• a second propulsion shaft coupling the front axle with the transmission;
• a rear axle configured to be driven by the engine through the transmission;
• a third propulsion shaft coupling the rear axle with the transmission;
• a gearset;
• a fourth propulsion shaft coupling the gearset with the transmission;
• a generator coupled with the gearset and configured to be intermittently driven to produce electric power thereby;
• a motor electrically coupled with the generator;
• and
• a gearbox through which the second propulsion shaft extends;
• wherein the motor is configured to drive the front and rear axles through the gearbox.
