Abstract:
A hybrid powertrain has a suitable heat engine having rotational output, a multi-speed transmission and a motor/generator (MG). The transmission input or cluster shaft is continuously connected with the MG. One set of ratio gears in the transmission is continuously drivingly connected to an accessory drive. The cluster shaft and a main shaft are selectively interconnected through a plurality of sets of ratio gears that are activated through the selective engagement of synchronizers associated with the ratio gears on the main shaft. The engine is selectively drivingly connected with the cluster shaft through a launch device such as a friction clutch. The output of the transmission, a differential, can be driven by the engine only, by the MG only or by a combination of the engine and the MG. The accessory mechanism is selectively connectable with the accessory drive and may also be driven under the same conditions as the transmission output as well as by the MG when the engine is off and the vehicle is stationary.
