摘要： In an aspect, a tensioner is provided for tensioning an endless drive member that is engaged with a rotary drive member on a shaft of a motive device. The tensioner includes a base that is mountable to the motive device, a ring that is rotatably supported by the base in surrounding relationship with the shaft of the motive device and which is rotatable about a ring axis, a tensioner arm pivotally mounted to the ring for pivotal movement about an arm pivot axis, and first and second tensioner pulleys. The first tensioner pulley is rotatably mounted to the tensioner arm. The tensioner arm is biased towards a first span of the endless drive member on one side of the rotary drive member. The second tensioner pulley is rotatably mounted at least indirectly to the ring and is biased towards a second span of the endless drive member on another side of the rotary drive member. The ring is rotatable in response to hub loads in the first and second tensioner pulleys that result from engagement with the first and second spans of the endless drive member.

摘要： In an aspect, an electromechanical apparatus is provided, comprising an electromagnet, a magnetically permeable rotor, a drive, a current source, a current sensor and processing logic. The electromagnet includes a magnetically permeable housing and a wire coil disposed therein. The rotor spins and is disposed in the path of a magnetic circuit generated by the electromagnet. The drive rotates the rotor relative to the electromagnet housing. The rotor and electromagnet housing vary the reluctance therebetween as the rotor rotates. The current source applies a current to the electromagnet coil, wherein, during rotation of the rotor, fluctuations in the current result in the electromagnet coil due to the aforementioned varying reluctance are superimposed on the applied current. The current sensor senses fluctuations in current in the electromagnet coil. The processing logic reads the sensed current and determines the frequency of the fluctuations, which are correlated to rotor speed.

摘要： In an aspect, a tensioner is provided for tensioning a belt and includes first and second tensioner arms having first and second pulleys respectively. The first and second pulleys are configured for engagement with first and second belt spans, and are biased in first and second free arm directions respectively. A second tensioner arm stop is positioned to limit the movement of the second tensioner arm in a direction opposite the second free arm direction. The second tensioner arm stop is positioned such that, in use, the second pulley is engaged with the endless drive member while the second tensioner arm is engaged with the second tensioner arm stop throughout a first selected range of operating conditions.

摘要： In an aspect, a decoupler includes a hub, a pulley, a torsion spring having a plurality of coils including first and second end coils, a first spring driver fixed to the pulley, and having a first spring driver surface and a first end coil support surface; a second spring driver not fixed to the pulley, and having a second spring driver surface and a second end coil support surface, a driving clutch member mounted connected to the second spring driver, a driven clutch member mounted concentrically with the driving clutch member and drivingly connected to the hub, a one-way wrap spring clutch mounted about the hub and disposed to interconnect the driving and driven clutchmembers, and configured to transfer torque in a first direction between the driving and driven clutchmembers. A first overrun limit surface connected to the first spring driver engages a second overrun limit surface connected to the second spring driver when an angular displacement of the second spring driver relative to the first spring driver reaches a first selected angular displacement so as to prevent an increase in the angular displacement. At the selected angular displacement any axial compression of the torsion spring resulting from rotation of the second end coil support surface relative to the first end coil support surface is sufficiently small to prevent the coils from binding to one another.

摘要： In one aspect, a decoupler comprises an input member, an output member, and a torsional isolation spring, a carrier, and a wrap spring clutch configured to operate in a first mode in which rotary power is transmitted in a first rotational direction from the input member to the output member serially through the wrap spring clutch, the carrier, and the isolation spring, and a second mode in which the output member overruns the input member in the first rotational direction. The carrier has a carrier clutch drive face that receives a first vector force from an end of the wrap spring clutch, and an isolation spring drive face that receives a second vector force from an end of the isolation spring. The wrap spring clutch and isolation spring drive faces are arranged so as to direct the second vector force to intersect with the first vector force substantially at the carrier clutch drive face.

摘要： In one aspect, a decoupler assembly is provided for use between a shaft and an endless drive member that is used to drive the shaft. The decoupler assembly includes a pulley, a hub and an isolator spring that is preferably a coiled torsion spring. The two ends of the spring are engageable, at least indirectly, with the pulley and the hub for the transfer of torque therebetween. At least one of the ends of the spring engages an engagement structure (on either the pulley or the hub) that includes a helical axial shoulder and a driver wall. The spring transfers torque in one direction through the driver wall (e.g. when the pulley overruns the hub), but the spring end is not fixedly connected to the driver wall. When the hub overruns the pulley, there is relative rotation between the spring and whichever of the hub and pulley it is not fixedly connected to. Accordingly, there is relative rotation between the spring end and the helical axial shoulder and the driver wall. This causes the spring end to separate from the driver wall and ride up the helical axial shoulder. This causes the spring to compress axially. The spring coils have a selected amount of spacing so that the spring can be compressed by a selected amount axially. This sets the amount of relative rotation (and the amount of overrun) that is available between the pulley and the hub in the situation when the hub overruns the pulley. In some embodiments, the decoupler assembly may be configured such that the selected amount of spacing of the spring coils sets the amount of relative rotation (and therefore overrun) that is available between the pulley and the hub when the pulley overruns the hub.
摘要翻译：在一个方面，提供一种用于在用于驱动轴的轴和环形驱动构件之间使用的分离器组件。分离器组件包括滑轮，轮毂和隔离器弹簧，其优选地是螺旋扭转弹簧。弹簧的两端可以至少间接地与滑轮和轮毂接合，以在它们之间传递扭矩。弹簧的至少一个端部接合包括螺旋轴向肩部和驱动器壁的接合结构（在滑轮或轮毂上）。弹簧通过驱动器壁（例如当滑轮超过轮毂时）在一个方向上传递扭矩，但弹簧端没有固定地连接到驱动器壁。当轮毂超过滑轮时，弹簧与其未固定连接的轮毂和滑轮之间存在相对旋转。因此，在弹簧端和螺旋轴向肩部和驱动器壁之间存在相对旋转。这使得弹簧端与驱动器壁分离并且爬上螺旋轴向肩部。这导致弹簧轴向压缩。弹簧线圈具有选定的间隔量，使得弹簧可以轴向地被压缩选定的量。在轮毂超过滑轮的情况下，这将设置滑轮和轮毂之间可用的相对旋转量（以及超速量）。在一些实施例中，分离器组件可被配置为使得当滑轮超过轮毂时，弹簧线圈的选定量的间隔设定滑轮和轮毂之间可用的相对旋转量（并因此超出）。
