Abstract: A torque transmitting mechanism includes a drum attached to one of a first member and a second member, and a shell attached to another of the first member and the second member. The drum and the shell are concentrically disposed about a longitudinal axis, with the shell concentrically disposed about the drum. An electric motor includes a stator, and a first rotor rotatable about the longitudinal axis relative to the stator. A band is coupled to the shell, wrapped around the drum between four and twelve complete revolutions, and includes a first end attached to the first rotor for rotation with the first rotor. The band includes a second end attached to a reaction member. Rotation of the first rotor tightens the band against the drum to bias the drum against the shell, to transmit torque between the first member and the second member.

Abstract: A hybrid vehicle has a powertrain that includes a transmission with a planetary gear set that has a first, a second, and a third member. An engine is connected for unitary rotation with the first member. A first final drive is operatively connectable with the carrier member and connected with the first axle. A first motor-generator is connected for unitary rotation with the third member. A second motor-generator is operatively connected for proportional rotation with one of the axles. A first clutch is selectively engageable to connect any two of the members for unitary rotation with one another. The planetary gear set provides an underdrive ratio of speed of the second member to speed of the engine when the sun gear member is stationary.

Abstract: A vehicle's electrified powertrain includes a battery pack linked to a traction power inverter module (TPIM) converting DC voltage from the battery pack into AC voltage. A rotary electric machine includes a stator energized by the TPIM's AC voltage, enclosing a rotor core capable of rotation. The rotor core contains slots holding conductive bars and permanent magnets, with conductive bars positioned closer to the rotor core's center. The conductive bars and permanent magnets are separated by gaps within each slot. An annular end ring assembly is present at one end of the rotor core, featuring terminal conductors connected to subsets of conductive bars and a secondary coil of a rotary transformer. When the stator is energized, the rotor shaft, connected to the rotor, rotates. The electric machine powers a transmission, which is coupled to the rotor shaft.

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.
