摘要： In one aspect, a rotary device is provided, and includes a shaft adapter, a chambered member, a seal member and at least one internal torque transfer member. The shaft adapter is connectible to a crankshaft or accessory shaft and defines an axis. The chambered member (e.g. a pulley) is rotatably connected to it, and at least partially encloses a chamber (e.g. for oil), and includes a circumferential portion, a first side wall, and a second side wall which is a separate member from the circumferential portion. One of the circumferential portion and the second side wall has projections thereon, and the other has valleys that mate with the projections with no clearance, so as to be able to transfer a torque of at least 10 Nm into one another without plastic deformation. A seal member is compressed between the second side wall and the circumferential portion.

摘要： 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.

摘要： 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.

摘要： A clutch system includes a rotary input member, a wrap spring clutch and a rotary output member. The wrap spring clutch has a first end, a second end, and a plurality of coils. The stiffness of the wrap spring clutch is selected such that, when transmitting less than a selected coil engagement torque, the clutch system transmits torque helically from the rotary input member, to the second end, helically through the wrap spring clutch to the first end, and into the rotary output member. When transmitting more than the selected coil engagement torque, the clutch system transmits torque in parallel from the rotary input member, to the second end, helically through the wrap spring clutch to the first end, and into the rotary output member, and from the rotary input member through the coil engagement surface, to the first end, and into the rotary output member.
