Patent number: 7886887Abstract: An embodiment provides a friction clutch apparatus that includes a disk assembly disk. The disk assembly has a disk portion selectively coupled to a first member, and a hub portion selectively coupled to a second member. The hub portion is generally axially aligned with the disk portion. The disk portion is rotatable relative to the hub portion. The disk assembly selectively transmits a torque between the first member and the second member. The disk assembly also includes an energy storage member selectively damping the relative rotation between the disk portion and the hub portion. The damping includes relative rotation between the disk portion and the hub portion. The energy storage member is preloaded, thereby requiring a preselected amount of torque to be applied by one of the disk portion and the hub portion to the other of the disk portion and the hub portion prior to the relative rotation.Type: GrantFiled: February 3, 2006Date of Patent: February 15, 2011Assignee: Eaton CorporationInventors: Michael L.

Patent number: 6666313Abstract: A dual mass flywheel and clutch system for minimizing torsional vibration levels during engine start-up and during low speed engine operation where the rotational moment of inertia of a clutch input assembly is minimized to raise the torsional natural frequency of the dual mass clutch system above the engine firing frequency when the clutch is disengaged to reduce the level of torsional vibration during engine start-up. After engine start-up, the dual mass clutch system is engaged and the torsional natural frequency of the clutch system returns to a lower frequency due to the rotation of the clutch output assembly thereby effectively reducing the torsional vibration levels in the vehicle driveline in a normal manner.Type: GrantFiled: March 27, 2002Date of Patent: December 23, 2003Assignee: Eaton CorporationInventors: Daniel V.

Patent number: 6039163Abstract: A method of balancing a clutch disc using one or more balancing weights inserted into balancing voids formed in the clutch disc carrier plate which are trapped between the friction facings. A first method involves determining the imbalance of the complete clutch disc assembly and then partially removing a friction facing so that a balancing weight can be inserted into a balancing void formed in the carrier plate. In a second method, the imbalance of the carrier plate and friction facings are separately measured prior to assembly. The most favorable rotational orientation is determined and then the number, size and location of one or more balance weights are determined and the balance weights are inserted into the balance voids. The friction facings are then assembled to the carrier plate thereby trapping the balance weights in position.Type: GrantFiled: February 11, 1999Date of Patent: March 21, 2000Assignee: Eaton CorporationInventors: Michael L. Bassett, Gregory W. Batterton, Andrzej P. Szadkowski
