  • Patent number: 11939911
    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.

  • Publication number: 20230336051
    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.

  • Patent number: 11732774
    Abstract: In an aspect a device for a driven shaft is provided that receives an input torque that varies cyclically between a peak input torque and a low input torque at a peak input torque frequency, which includes a shaft adapter, a rotary drive member, at least one isolation member, a torsional vibration damping structure including an inertia member and a elastomeric damping member, and a supplemental damping structure. The supplemental damping structure applies a supplemental damping torque to resist relative movement between the rotary drive member and the inertia member in addition to damping provided by the elastomeric damping member. A sum of torques including the supplemental damping torque limits a maximum twist between a first end of the driven shaft and a second end of the driven shaft, to below a yield point of the driven shaft.

  • Publication number: 20210345886
    Abstract: In an aspect, there is provided a temperature scanner for measuring a temperature of a selected area on a human subject having a first eye and a second eye. The temperature scanner includes an infra-red sensor, a first reflective surface region, a second reflective surface region, and a controller. The infra-red sensor has a selected field of view so as to detect a temperature of the selected area of the human subject when the selected area is positioned to completely fill the field of view. The first reflective surface region is concave, has a first principal axis, and has a first focal point along the first principal axis. The first reflective surface region and the second reflective surface region are positioned relative to the infra-red sensor such that positioning the first eye of the human subject at a selected first eye position and positioning the second eye of the human subject at a selected second eye position positions the selected area of the human subject to completely fill the field of view.
