摘要： In an aspect, a power transfer device, such as a decoupler, is provided for transferring torque between a shaft and a belt. The device includes: a hub configured to couple to the shaft, a pulley rotatably coupled to the hub that includes a power transmitting surface configured to engage the belt, an isolation spring to transfer a rotational load from one of the pulley and the hub to the other of the pulley and the hub, optionally a one-way clutch to permit overrunning of one of the pulley and the hub relative to the other of the pulley and the hub in a first direction, and a damping member positioned to be driven into frictional engagement with a friction surface by a force from the isolation spring acting on the damping member that varies based on the rotational load transferred by the isolation spring.

摘要： A damper device includes a first rotor, a second rotor, a plurality of elastic members, and a spring seat. The spring seat includes an end surface support portion and an outer periphery support portion. The end surface support portion includes a recess on a radially middle part thereof. The recess is recessed toward at least one of the elastic members. The end surface support portion supports one end surface of the at least one of the elastic members. The end surface support portion is supported by a pressing surface of a first accommodation portion of the first rotor and a pressing surface of a second accommodation portion of the second rotor. The outer periphery support portion supports part of a radially outer part of the at least one of the elastic members.

摘要： A rotor assembly for a hybrid module includes a rotor carrier, a rotor segment, an end ring, a first spacer, a second spacer, and a compressed spring. The rotor carrier includes a first outer cylindrical surface and a radial surface, and the rotor segment is installed on the first outer cylindrical surface. The end ring is fixed to the rotor carrier and arranged for fixing to an engine flexplate. The first spacer is disposed axially between the rotor segment and the radial surface, and the second spacer is disposed axially between the rotor segment and the end ring. The compressed spring is disposed axially between the end ring and the second spacer to press the first spacer, the second spacer, and the rotor segment against the radial surface for frictional torque transmission between the rotor segment and the rotor carrier.

摘要： An example robot includes: a motor disposed at a joint configured to control motion of a member of the robot; a transmission including an input member coupled to and configured to rotate with the motor, an intermediate member, and an output member, where the intermediate member is fixed such that as the input member rotates, the output member rotates therewith at a different speed; a pad frictionally coupled to a side surface of the output member of the transmission and coupled to the member of the robot; and a spring configured to apply an axial preload on the pad, wherein the axial preload defines a torque limit that, when exceeded by a torque load on the member of the robot, the output member of the transmission slips relative to the pad.

摘要： A tooth driven over-torque protection mechanism for use in a slack adjuster or as an air disc brake clutch, includes a shaft, toothed gear, a clutch device, a first spring, and a second spring. The toothed gear is disposed on the shaft. The toothed gear has a first pinion teeth set that extends along a first direction and a second teeth set that extends along a second direction. The clutch device that is also disposed on the shaft and includes an upper cam and a lower cam. The first spring biases the toothed gear against the clutch device. The second spring biases the clutch device against the toothed gear. The upper cam has cam teeth that cooperate with the second teeth set of the toothed gear in a torque transmitting manner, such that a torque applied in a clockwise direction to the first pinion teeth is transmitted to the upper cam through the second teeth set, but torque applied in a counterclockwise direction is opposed by the first spring.

摘要： An excessive torque releasing type clutch apparatus comprises an outer ring, an inner ring arranged radially inside and coaxially with the outer ring and rotatably relative to the outer ring, a torque transmitting portion capable of transmitting torque between the outer ring and the inner ring, and a restricting mechanism for restricting excessive torque from being input from an input torque transmitting member to a driving ring of the outer ring and the inner ring and restricting excessive inverse torque that is input to a driven ring of the outer ring and the inner ring from being input to the input torque transmitting member. Treatment steps for securing strength of constituent members of the clutch apparatus in manufacturing be simplified or omitted.

摘要： A power transmission device includes a flywheel and a torque limiter unit fixed to the flywheel. The flywheel includes an annular portion and an accommodation portion provided on an inner peripheral side of the annular portion to accommodate the torque limiter unit. The torque limiter unit includes a first plate, a second plate, a friction disc disposed between the first and second plates, and a pressing member. A torque is inputted to the first plate. The first plate includes first engaging portions. The second plate is axially opposed to and non-rotatable relative to the first plate. The second plate includes second engaging portions engaged with the first engaging portions. The pressing member presses the second plate onto the friction disc. The annular portion of the flywheel is provided with recesses on the inner peripheral surface thereof. The recesses are recessed radially outward in opposed positions to the second engaging portions.
