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 5 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 10 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 pulley assembly having first and second members. The first member is capable of cooperating with a power transmission belt to drive/be driven by the belt. The first member is movable guidingly relative to the second member around a first axis. A coil spring has a length and a circumference and a first portion attached to the first member and a second portion attached to the second member so that a force tending to move the first/second member around the first axis is transmitted through the coil spring to the second/first member. At least one of the first and second members has a groove bounded by a surface into which the respective portion of the coil spring is fit. The respective portion of the coil spring is clamp fit within the groove.

摘要： An intake manifold (18) for an engine (10) includes a Roots-type supercharger (26) having a torsion damping mechanism (54) for reducing audible gear tooth rattle of timing gears (72,74) which prevent contact of meshed lobes (28c,29a) of the supercharger rotors (28,29). The damping mechanism includes a drive member (90), having an annular band portion (90d) for maintaining the shape of an annular member (98) formed of relatively soft elastomeric material which is fixed for rotation with the drive member via lugs (90e). The member (98) includes three arcuate slots (98d) each defining forward and reverse direction stops (98e,98f) for limiting movement of pins (94) slidably disposed at one end in the slots and fixed at the other end to the gear (74). A torsion spring (96) of low rate resiliently connects the annular member to the pins for reducing the audible gear tooth rattle. Member (98) is snugly constrained against deformation by the annular band (90d) and audible impacts of the stops (98e,98f) is mitigated by the soft material of the annular member (98).

摘要： A torque transmitting shaft includes a first member and a second member. The first member extends along an axis and has an inner surface extending between a first end and a second end. The inner surface defines a plurality of first engagement elements disposed proximate the first end. The second member extends along the second axis and has a first end portion and an intermediate portion extending from the first end portion. An end of the intermediate portion is fixedly attached to the second end. The first end portion has a first spline portion and each member of the first spline portion is received within corresponding engagement elements of the plurality of first engagement elements.
