Transmission with energy storage and ancillary drives

摘要

The transmission system has an energy storage element (6) coupled to the engine by a first clutch (4) and to the transmission by a second clutch (8). The ancillary systems are grouped into primary circuits, which are driven directly off the engine, and others which are driven off the transmission. The secondary systems are driven off the engine by a selective clutch (17) and off the transmission on the output side of the second clutch. The energy storage element is used to provide additional torque eg. when starting. For priority drive for certain ancillary systems they can be driven off the transmission using the stored energy if the engine is disconnected.
