摘要： A belt tensioner for a motor vehicle engine comprises a pivot shaft and an eccentric pivoted structure mounted for pivoted movement on the pivot shaft. The belt tensioner has a rotatable pulley member mounted for rotation on the eccentric pivoted structure. A spring is constructed and arranged to bias the eccentric pivoted structure in a direction tending to force the rotatable pulley member into tensioning engagement with a belt trained about the pulley member. A mounting bolt is constructed and arranged to mount the belt tensioner on the motor vehicle engine, said pivot shaft being movable relative to said mounting bolt and towards said belt during a belt tensioner installation procedure. A linear guiding structure provides surfaces of interengagement between said belt tensioner and said motor vehicle engine to limit movement of the pivot shaft to linear movement toward the belt during the installation procedure. The present invention also relates to a method of installing a belt tensioner in which the pivot shaft moves in a substantially exactly linear fashion as the tensioner is moved into tensioning engagement with the belt. In a preferred embodiment, when the belt tensioner is moved into tensioning engagement with the belt, an external force is applied to the tensioner to balance any belt load forces tending to tilt the tensioner during installation. The present invention also discloses a tensioner that has contact portions that oppose the tilting force applied by the belt during installation, and a portion that extends beyond the contact portions to facilitate installation.

摘要： A crankshaft decoupler has a mounting hub, a pulley rotatably mounted on the mounting hub, an annular carrier mounted within said pulley, a biasing device mounted therebetween, and a one way clutch mounted between the annular carrier and the pulley. The biasing device cushions the belt drive from crankshaft impulses and lowers the angular resonant frequency of the belt system. The one way clutch prevents sudden reversal of the belt tension in the drive due to start/stop of the engine or sudden deceleration of the engine and prevents momentary reverse slip belt squeal as a result of the tensioners' inadequate output for the reverse mode. The one way clutch limits the maximum amount of torque which may be transmitted preventing belt slippage during momentary overload.

摘要： A belt tensioner having a sleeve bearing pivotally mounting a pivoted structure on a fixed structure for spring pressed movement between first and second positions. The sleeve bearing is larger than and surrounds a ball bearing assembly rotatably mounting a pulley on the pivoted structure. The pulley has a cantilevered rim which axially overlaps and annularly surrounds the sleeve bearing. One of the structures and the sleeve bearing have slidably interengaging surfaces which are compressed together by the belt load force in the pivoted structure and the reactionary force acting in the fixed structure so as to provide a damping torque resistance to the pivotal movement of the pivoted structure which prevents movements resulting from dynamic changes in the belt load force within a range. The arrangement is such that independent vibrational forces instantaneously release the damping torque resistance to permit instantanteous movements otherwise prevented.

摘要： A belt tensioner comprising a pivoted structure carrying a pulley for rotation about a rotational axis and mounted on a fixed structure for pivotal movement between an increased range of angular movement. The pulley is operatively positioned with respect to its rotational axis and the pivotal axis of the pivoted structure such that the lever arm to the pivotal axis through which the generally constant belt load force acts on the pivoted structure increases at a decreasing rate and then decreases at an increasing rate throughout the range of movement of the pulley between its first and second positions in a direction toward the second position. The spring assembly is operatively associated with the pivoted structure so as to apply a spring torque to the pivoted structure which increases at a decreasing rate and then decreases at an increasing rate throughout the range of movement of the pulley between its first and second positions in a direction toward said second position.

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： In one aspect, there is provided a decoupler for an accessory drive for an engine. The decoupler includes a decoupler input member and a decoupler output member. One of the decoupler input member and the decoupler output member has a clutch engagement surface. The decoupler further includes a wrap spring clutch and an isolation spring that act in series in a torque path between the decoupler input member and the decoupler output member. The wrap spring clutch has a radially inner surface and a radially outer surface. One of the radially inner and outer surfaces engages the clutch engagement surface in an interference fit with the clutch engagement surface. The decoupler further includes a volume of lubricant. During sufficiently high acceleration of the decoupler input member, there is slippage at the wrap spring clutch for a selected period of time after which the slippage stops.

摘要： An automotive air conditioning assembly including a scroll compressor and a wrap spring clutch. The wrap spring clutch enables the use of a comparatively smaller pulley (a diameter of at most 85 mm) which comparatively increases the compressor speed and hence cooling capacity at a given engine speed. The clutch requires low power (e.g. less than 5 Watts) for continuous operation.

摘要： A rotary clutch uses a wrap spring clutch. An actuator generates a drag force to control the wrap spring clutch to engage or disengage the clutch. The actuator includes an electromagnet, a two-component armature and an axial return spring. The two-component armature includes first and second components threadingly connected one another for relative axial translation as they rotate relative to one another, and an angular position biasing member connecting them. The second component translates axially under magnetic force from the electromagnet, and when stopped by the electromagnet the first armature component translates axially due to their threaded connection. Due to the previous axial movement of the floating component the translation of the first armature component occurs in conditions where the air gap and reluctance of a magnetic circuit is reduced compared to the prior art, and thus the overall strength of the applied magnetic field can be comparatively reduced.
