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： An articulated chain with alternating inner chain links and outer chain links which are each connected to each other by means of a chain joint, wherein each outer chain link comprises at least two outer link plates and two chain studs connecting them to each other, each inner chain link comprises at least two inner link plates and two joint sleeves connecting them to each other, and for forming a chain joint, one chain stud each of the outer chain link extends through a joint sleeve of the inner chain link. The joint sleeves of the inner chain links are embodied as winding sleeves and firmly connected to the inner link plates, wherein the sleeve joints of the two winding sleeves are positioned on the same side of a link plate's longitudinal axis and face each other, and the sleeve joints are arranged at a distance to the link plate's longitudinal axis and at a distance to an upper apex or to a lower inflection point of the winding sleeve.

摘要： To provide a simple-structured tensioner lever capable of consistently exerting a correct reaction force to various fluctuations of tension accompanying varying chain behaviors, whereby vibration and noise when the chain runs can be reduced. The tensioner lever of the present invention includes a lever body having a shoe surface that slidably guides a chain; a first pressing spring configured to have a first pressing arm extending from one end of a first helical part, with a distal end portion contacting the lever body to form a first loading point, and a first support arm extending from the other end of the first helical part, with a distal end portion contacting and being supported by a first support part provided to an attachment surface to form a first support point; and a second pressing spring supported on the lever body at a different position from that of the first pressing spring.

摘要： Described herein is a tensioner device, and assemblies and methods of manufacture thereof. The tensioner device may be adapted to create a target tension in an associated belt based on the measured length of the belt and/or measure characteristics of a biasing element, such as a stiffness of the biasing element. A biasing element may exhibit a measured stiffness and be associated with a damping assembly and a base of the tensioner device. An engagement member may be associated with the damping assembly for movement therewith and angularly displaceable relative to the base and the biasing element to tension the belt. In one example, the biasing element may be connected to the damping assembly at a position determined by the measured stiffness to define a value of the angular displacement of the engagement member relative to the biasing element and create a target tension in the belt.

摘要： A belt drive comprises a first pulley and at least one additional pulley and uses an elastic belt that is engagable over the pulleys. An auxiliary unit, connected to the first pulley, has a detent. A tensioning link comprises an open-ended slot for receiving in a slidable manner the detent. In an operating position of the belt drive the detent is locatable at a closed end of the open-ended slot and to obtain a belt changing position the detent is movable along the open-ended slot towards an open end of the open-ended slot. Movement of the detent along the open-ended slot requires simultaneous rotation of the auxiliary unit.
