DUAL CLUTCH POWERTRAIN ARCHITECTURE

摘要

A powertrain architecture includes an engine and a transmission coupled through a launch device that is configured to be selectively mechanically coupled to the engine and to the transmission. A ring gear is positioned at least partially around the launch device. An engine lock up clutch mechanically couples the engine to the ring gear. A turbine lock up clutch mechanically couples the launch device to the ring gear. Ancillary devices are provided to receive power from or transmit power to the ring gear. The engine lock up clutch and the turbine lock up clutch selectively engage the ring gear to power at least one ancillary device.

1. A powertrain architecture comprising:
an engine; a transmission; a launch device configured to be selectively mechanically coupled to the engine and to the transmission; a ring gear positioned at least partially around the launch device; an engine lock up clutch operative to selectively mechanically couple the engine to the ring gear; a turbine lock up clutch operative to selectively mechanically couple the transmission to the ring gear; and at least one ancillary device coupled to the ring gear for receiving power from or transmitting power to the ring gear.
