Abstract: A clutched pulley assembly mountable to the shaft of a motor-generator unit (MGU) has a first sheave, with first spline teeth, rotatably mounted to the MGU shaft, and a second sheave, with second spline teeth, fixed to the MGU shaft. A slider gear with slider gear spline teeth is axially moveable between a torque transfer position, where the slider gear spline teeth simultaneously intermesh with the spline teeth of the first and second sheaves to operatively connect the sheaves to each other, and a torque cut-off position, where the slider gear spline teeth intermesh with the second sheave spline teeth but not the first sheave spline teeth so as to operatively disconnect the sheaves. An actuator drives the slider gear between the torque transfer and cut-off positions. The pulley assembly can be used in a stand-cooling mode wherein the engine is stopped but the MGU powers a load.

Abstract: In an aspect, an actuator is provided and includes an axial flux motor and an epicycloid gear arrangement. The axial flux motor has a motor stator and a rotor, the rotor defining a rotor axis and having a motor output shaft. The motor output shaft has a first shaft portion that is coaxial with the rotor axis and a second shaft portion that is offset from the rotor axis. The epicycloid gear arrangement includes a ring gear, a cycloid gear, and a gear arrangement output member. The cycloid gear is rotatably mounted to the second shaft portion of the motor output shaft such that rotation of the motor output shaft drives the cycloid gear about the ring gear. The gear arrangement output member is driven rotationally by the cycloid gear about a gear arrangement output member axis that is fixed.
