摘要： A differential drive system includes an electric motor for generating an electric motor torque and an input planetary gear-set operatively connected to the electric motor to receive the electric motor torque. The input planetary gear-set has first, second, and third members. The first member receives the electric motor torque, the second member provides a first input torque in a first rotational direction in response to the electric motor torque, and the third member provides a second input torque in a second rotational direction, opposite the first direction, in response to the electric motor torque. The system also includes a first output gear-set operatively connected to the input planetary gear-set, and providing a first output torque in response to the first input torque. The system additionally includes a second output gear-set operatively connected to the input planetary gear-set and providing a second output torque in response to the second input torque.

摘要： A hybrid powertrain includes an internal combustion engine and a multi-speed transmission coupled to the internal combustion engine. The multi-speed transmission includes an input member, an output member, and a first, second, third, fourth, and fifth planetary gear set each having a sun gear member, a planet carrier assembly member and a ring gear member. The multi-speed transmission further includes a first, second, third, fourth, and fifth planetary gear sets each having a sun gear member, a planet carrier assembly member and a ring gear member. The multi-speed transmission further includes seven torque-transmitting devices configured to selectively interconnect the first, second, third, fourth, and fifth planetary gear sets with one another in combinations of at least four to establish at least ten forward speed ratios and at least one reverse speed ratio between the input member and the output member.

摘要： The present disclosure provides a transmission clutch assembly having a drum, a brake band, a smart material band and an electrical circuit. The brake band substantially encircles the drum and includes first and second ends, a high friction inner surface, and a low friction outer surface. The smart material band includes a beginning end and a terminating end wherein the beginning end of the smart material band is coupled to the second end of the brake band while the terminating end of the smart material band is coupled to the first end of the brake band. The electrical circuit transfers an electrical current to the smart material band. The smart material band contracts when the electrical current is applied to the smart material band thereby drawing the first and second ends of the brake band closer and contracting the brake hand against the drum to restrict drum movement.

摘要： A vehicle powertrain includes first and second power sources and a transmission assembly having first and second input members and an output member. The transmission assembly also includes a first planetary gear-set connected to the first input member and a second planetary gear-set connected to the second input and the output members. The transmission assembly additionally includes a transmission housing retaining the first and second gear-sets. Furthermore, the transmission assembly includes a first torque-transmitting device for connecting one first gear-set node to the housing and a second torque-transmitting device for connecting a first gear-set node not connected to the housing to one second gear-set node. One first gear-set node is directly and continuously connected to one second gear-set node. The first power source is operatively connected to a node of the first gear-set and the second power source is operatively connected to a node of the second gear-set.
