摘要:
A hybrid powertrain includes an internal combustion engine, at least one electric machine and a multi-speed transmission. The electric machine is connected to a shaft between the internal combustion engine and the multi-speed transmission. The transmission is provided having an input member, an output member, four planetary gear sets, a plurality of coupling members and a plurality of torque transmitting devices. Each of the planetary gear sets includes a sun gear member, a planet carrier member, and a ring gear member. The torque transmitting devices include clutches and brakes arranged within a transmission housing.
