Abstract: A clutch device for a clutch system has an input member that rotates at a first speed. A friction drive system is disposed between the input member and an output member. The clutch device is selectively movable by a fluid actuator assembly, between an engaged position in which the friction drive system drives the output member to rotate at the first speed, and a disengaged position in which a viscous drive system rotates the output member at a second speed slower than the first speed. A variable viscous fluid supply assembly includes a viscous fluid storage chamber, a valve, and a valve actuator that selectively drives the valve to move between an open position and a closed position to control an amount of viscous fluid available to the viscous drive system, thereby varying the second speed.

Abstract: A tensioner system may be replaced by selecting replacement components. Components such as a housing, roller arm, pulley, and index plate locating pin may be selected from a group of housings, roller arms, pulleys, and index plate locating pins, respectively. The selection of the components allows a user to assemble multiple variations of tensioner that are commercially available. The location of the index plate locating pin on the index plate allows for proper orientation of the tensioner in the vehicle in order to apply the proper tension to a belt. The selection of the components may be based on current tensioner model, or based on dimensions measured from the current tensioner.

Abstract: A clutch device for a clutch system has a nose cap and a piston that is movable in an axial direction with respect to the nose cap. A seal disposed in the axial direction between the nose cap and the piston automatically locks the clutch device when a threshold amount of wear has accrued in a friction interface of the clutch device. If the seal is not compressed in the axial direction, then a pressurized fluid can flow past the seal and the piston is displaced in the axial direction away from the nose cap. If the seal is compressed in the axial direction, then the pressurized fluid does not flow past the seal and the piston is not displaced in the axial direction away from the nose cap.

Abstract: A clutch device for a clutch system has an input member that rotates at a first speed. A friction medium is disposed between the input member and an output member. The output member rotates on a bearing coupled to a piston. The piston translates relative to the input member, between an engaged position in which the friction ring frictionally engages with the input member, thereby driving the output member to rotate at the first speed, and a disengaged position in which the friction ring is spaced apart from the input member. A biasing member urges the piston toward the engaged position. A pressurized fluid in a fluid receiving chamber selectively urges the piston toward the disengaged position. A resistance member disposed in a chamber containing a viscous fluid transfers torque from the input member to rotate the output member at a second speed.
