Abstract
A parallel (P2) hybrid electric vehicle (HEV) powertrain assembly includes a torque converter and a motor-generator unit (MGU). The parallel hybrid electric vehicle (HEV) powertrain assembly can be equipped in a front wheel drive (FWD) powertrain architecture. The torque converter has an impeller cover. The motor-generator unit has a rotor and a stator. The rotor extends from the impeller cover, and the stator is mounted to a transmission bell housing.
Claims20
A parallel hybrid electric vehicle (HEV) powertrain assembly, comprising:
- a torque converter having an impeller cover;
- and
- a motor-generator unit (MGU) having a rotor and a stator, the rotor extending from the impeller cover at an outboard side of the impeller cover and co-rotating with the impeller cover during use of the parallel hybrid electric vehicle powertrain assembly, and the stator being mounted to a powertrain housing at an inboard side of the powertrain housing and adjacent the rotor.
A parallel hybrid electric vehicle (HEV) powertrain assembly, comprising:
- a torque converter having an impeller cover;
- and
- a motor-generator unit (MGU) having a rotor and a stator, the rotor carrying at least one permanent magnet, the rotor extending from an exterior surface of the impeller cover and co-rotating with the impeller cover during use of the parallel hybrid electric vehicle powertrain assembly, and the stator being mounted to an interior surface of a transmission bell housing.
A front wheel drive (FWD) parallel hybrid electric vehicle (HEV) powertrain assembly, comprising:
- a torque converter including an impeller, a turbine, and a stator situated between the impeller and turbine, the torque converter further including an impeller cover;
- and
- a motor-generator unit (MGU) having a rotor and a stator, the rotor carrying at least one permanent magnet, the rotor extending from an exterior surface of the impeller cover, and the stator being mounted to an interior surface of a transmission bell housing;
- wherein the rotor of the motor-generator unit extends from the impeller cover at a location that is radially outboard of the impeller of the torque converter and that is radially outboard of the turbine of the torque converter;
- and
- wherein the torque converter augments rotational torque transfer of the motor-generator unit during use of the front wheel drive parallel hybrid electric vehicle powertrain assembly.
