摘要:
A hybrid powertrain is provided including an internal combustion engine sufficiently configured for operation in a homogeneous charge compression ignition mode of operation. An electric motor and an electric storage device are provided in parallel hybrid combination with the internal combustion engine. A transmission is operatively connected to the internal combustion engine and the electric motor. The engine may operate in one of a two-stroke and a four-stroke cycle.

A hybrid powertrain is provided that includes an engine operatively connected with an input member. The powertrain includes a transmission with first and second electric motor/generators, a differential gear set having multiple members, and selectively engageable torque-transmitting mechanisms. The input member, the output member, the engine and the motor/generators are selectively interconnected through the differential gear set by engagement of the torque-transmitting mechanisms in different combinations. The powertrain provides multiple operating modes between the input member and the output member, including an electric-only operating mode in which the engine is off and both electric motor/generators act as motors to provide torque at the output member.

An electric motor assembly includes a rotor hub, and a rotor supported on the rotor hub. The rotor hub has first and second hub portions, and the rotor has first and second annular rotor segments supported for rotation on the respective first and second hub portions. Each of the rotor segments has a respective set of magnets spaced circumferentially therearound. The rotor hub and the rotor segments are configured so that at least one of the rotor segments moves about the axis of rotation relative to the other of the rotor segments as the rotor hub rotates. The movement of the at least one of the rotor segments is an amount that increases as the speed of the rotor hub increases to reduce back electromotive force. The movement may be due to centrifugal force, which increases as speed increases, without requiring a control system to effect the movement.

An electric motor assembly includes a stator having a first set of electrical windings. The motor assembly includes a rotor assembly rotatable about an axis of rotation and that has a rotor with first and second rotor segments. Each of the rotor segments has a respective set of magnets spaced therearound. The motor assembly has a phaser that includes a phaser actuator and a phaser gear mechanism. The phaser gear mechanism has a plurality of members. The phaser actuator and the first and second rotor segments are each operatively connected to a different respective one of the members. The phaser actuator is activatable to change an angular position of the member to which the phaser actuator is operatively connected, moving one of the rotor segments about the axis of rotation relative to the other of the rotor segments to reduce back electromotive force in the first set of stator windings.
