planetary using the sun gear, controlled by the generator, to control the variability. The hybrid transmission has a separate cooling system with coolant, pump, heat exchanger, and reservoir. D.3.1.1 Case Subsystem The hybrid transmission structure is comprised of four (4) main castings (Figure D-6). The castings are fastened together with M8 and M6 threaded fasteners and sealed with RTV. All case sections are die cast aluminum designs and have extensive machining. The cases capture the powertrain components similarly to a standard transmission. Topdown assembly is used, utilizing the rear cover to locate the rear bearings. Shims and spacers are used to account for the tolerance stack-up. Figure D-6: Main eCVT Case Components 62
D.3.1.2 Gear Train Subsystem The power-flow for the hybrid transmission is outlined in Figure D-7. The three (3) main inputs in the transmission are the traction motor, generator, and ICE. They are combined to create a continuously variable transmission (Figure D-8) utilizing a singular planetary set. The sun gear speed and direction is controlled by the generator motor. The ring gear is linked to the traction motor via the transfer main transfer gear. The input from the ICE drives the planet carrier. The transmission gear ratio is controlled precisely. Traction Motor Generator Figure D-7: Transmission <strong>Power</strong>-Flow The traction motor and generator are controlled and powered by the electronics on the transmission. The differential is a typical automotive design and transfers power to the wheels. 63
