    摘要： A tensioner for an engine accessory drive system includes a tensioner arm pivotally mounted for movement between a free arm position and a load stop position. The tensioner arm includes a pulley which engages a belt. A piston, disposed in a cylinder, is pivotally linked to the tensioner arm. A spring urges the tensioner arm towards the free arm position. A moveable load stop member, controlled by an actuator, projects into the cylinder. The load stop member abuts the piston to thereby arrest movement of the tensioner arm and define the load stop position. The actuator may drive the load stop member against the piston to move the tensioner arm towards the free arm position so as to increase belt tension.

    摘要： In an aspect, a method is provided for controlling a clutch assembly having first and second rotatable clutch members. The method includes providing a wrap spring clutch having first and second ends. The phase angle between the first and second ends determines a diameter of the wrap spring clutch. One of the clutch members is connected with the first end. The method further includes obtaining a target value indicative of a target speed for the second clutch member, and determining through measurement an actual value that is indicative of an actual speed of the second clutch member. The method further includes changing the phase angle between the first and second ends of the wrap spring clutch to generate a selected amount of slip between the wrap spring clutch and the other of the first and second clutch members, based on the target value and the actual value.

    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.
