Abstract: An electrically and mechanically driven automotive accessory including a housing, an electric motor, a pulley, and a pulley assist mechanism. The electric motor comprises a stator assembly that is mounted to the housing and a rotating assembly that is mounted to a shaft. The electric motor creates a primary torque flow path that drives rotation of the rotating assembly relative to the stator assembly. The pulley is rotatable relative to the shaft and the rotating assembly. The pulley assist mechanism includes a plurality of circumferentially spaced teeth nested with a conductive body, a rotor body fixedly mounted to the shaft, and an electromagnet that is configured to induce a magnetic field between the circumferentially spaced teeth, the rotor body, and the pulley, which creates a secondary torque flow path between the pulley and the rotor body.

Abstract: A hybrid coolant pump assembly comprises a housing, a bearing shaft, and an impeller apparatus. The bearing shaft is rotatably supported within an internal cavity of the housing. A first clutch is disposed on the bearing shaft and is operable to drivingly interconnect an input member and the bearing shaft when in an engaged state. The impeller apparatus is positioned about the bearing shaft and configured to pump a fluid. A rotor, disposed within the internal cavity of the housing, extends about the bearing shaft. A stator, disposed within the internal cavity of the housing, extends about the rotor. The rotor rotates relative to the stator and the bearing shaft when the stator is electrically energized. The impeller apparatus is rotatably driven by the bearing shaft when the first clutch is in the engaged state. The impeller apparatus is rotatably driven by the rotor when the stator is electrically energized.

Abstract: A tool for roll-forming a noncircular lip of a component includes a central shaft, first and second axles, and first and second rollers. The central shaft has a longitudinal axis. The central shaft is adapted to rotate about the longitudinal axis. The axles extend from and are fixed to the central shaft. The axles have respective first and second lateral axes that extend substantially perpendicular to the longitudinal axis. The rollers are rotatably coupled to respective axles, adapted to rotate about the respective lateral axes, radially spaced with respect to the longitudinal axis, and circumferentially spaced with respect to each other. The first and second rollers are adapted to concurrently operably engage the noncircular lip, and deform the noncircular lip.

Abstract: An electric pump comprises an outer housing including a motor cavity and a controller cavity separated by a partition wall. An inner housing is positioned within the motor cavity of the outer housing. One of the inner and outer housings includes radially extending ribs positioned adjacent to the other of the inner and outer housings to define a coolant flow path between the inner housing and the outer housing. The flow path is partially defined by the partition wall. An electric motor is positioned within the inner housing and includes a hollow rotor shaft driving a pump member. The hollow rotor shaft forms a portion of the coolant path and interconnects a volume between the inner and outer housings with a low pressure cavity containing the pump member. A controller is positioned within the controller cavity in heat transfer relation with the partition wall.
