摘要： A component, such as an engine accessory for an automotive engine, that has clutch with a helical clutch coil and an axially movable armature. The helical clutch coil is normally engaged so as to transmit rotary power between a driving member and a driven member. The armature can be moved to apply a force to a tang of the helical clutch coil that causes the helical clutch coil to disengage to an extent where full rotary power is not passed through the clutch to drive the component.

摘要： A system and method is provided for determining changes in the angular position of a driven pulley, with respect to a driving pulley, when the driven and driving pulleys are synchronously linked by a flexible drive member such as a toothed belt or a chain. From these determined changes in the angular positions, the system and method can determine the condition of the flexible drive member and can output an appropriate signal when the condition of the flexible drive member has exceed a pre-defined value. Further, the system and method can detect a variety of other undesired conditions in the operation of an engine and/or the relative angular position information can be used to alter operation of the engine to improve the engine's operating efficiency and/or reduce the emissions created during operation of the engine.

摘要： A tensioner for tensioning a flexible drive means, such as a timing belt or chain, includes a pulley to contact the belt. The pulley is mounted on a tensioner arm and the tensioner arm can be rotated about a pivot shaft mounted to the tensioner by a spring. The axis about which the pulley rotates is spaced from the axis of the rotation of the tensioner arm with respect to the pivot shaft and the spacing of these axes of rotation results in the pulley moving through an eccentric towards or away from the belt when the tensioner arm is rotated. A stop is used to limit the range of movement of the tensioner arm between a desired range of movement defined by a free arm stop and a backstop. The position of the stop is adjustable by an installer. The angular range of movement installed tensioner. In one embodiment, the movement of the stop from the installation position to the nominal operating position also compensates the spring.

摘要： A tensioner for an endless belt comprising a stationary structure on which a pivotal tension arm with an idler pulley is mounted. A spring between the tension arm and the stationary structure acts to bias the pulley against the belt, thereby applying tension. The invention includes a one-way device that is operable in response to the extent of pivotal movement of the tension arm in the forward direction to establish different positions at which pivotal movement in the return direction is limited. A damping system is used to restrict pivotal movement of the tension arm as a result of sudden short-time vibratory movements or dynamic vibrations in cold conditions.

摘要： A tensioner having a backstop device which allows free rotation of the pivot arm in a first direction but controls rotation of the pivot arm in a second, opposite direction. The backstop device permits a predetermined, limited amount of free rotation in the second direction and thereafter, employs a braking device to prevent rotation in the second direction if the torque that acts on the pivot art is less than a predetermined threshold.

摘要： A timing belt tensioner for a motor vehicle engine comprising a pivot that is fixed relative to the motor vehicle engine. A tensioner arm is mounted for pivotal movement on the pivot. The tensioner arm has a friction surface disposed in friction sliding relation with an adjacent surface during the pivotal movement. A belt engaging pulley is mounted for rotation on the tensioner arm. A spring coupled with the tensioner arm biases the arm in a direction tending to force the pulley into tensioning engagement with the belt when the tensioner is installed on the motor vehicle engine. The spring biasing the arm into a working position maintains a predetermined range of tension in the belt during dynamic operating equilibrium of the belt. An anti-kickback stop mechanism is coupled with the arm and stops instantaneous kickback movement of the arm against the belt tensioning direction beyond when the arm is instantaneously moved away from the working position against the belt-tensioning direction in response to instantaneous tightening of the belt. The anti-kickback mechanism adjusts a location of the stop position based upon the working position of the arm.
