Patent number: 6874608Abstract: A frictional clutch for a motor vehicle includes a cover, a pressure plate, a biasing member, an adjustment mechanism and a dust shield assembly. The cover has an axis of rotation. The pressure plate is coupled to the cover for rotation therewith about the axis. The pressure plate has a frictional engagement surface substantially normal to the axis. The biasing member is interposed between the cover the pressure plate, and biases the pressure plate toward an engaged pressure plate position. The adjustment mechanism is centered about the axis and is located at a first radial distance from the axis. The adjustment mechanism is operably disposed between the biasing member and one of the pressure plate and the cover. The dust shield assembly includes an annular wall disposed radially within the adjustment mechanism. The annular dust shield assembly is in axial alignment with the adjustment mechanism.Type: GrantFiled: June 30, 2003Date of Patent: April 5, 2005Assignee: Eaton CorporationInventors: John D. Conrad, Roger E. Knueve, John D. Kroemer, Jonathan P. Young, Jeffrey S. Blessinger, John A. Schenkel, III

Patent number: 6827193Abstract: A friction torque device includes an adjustment mechanism for adjusting the device in response to wear on a friction surface within the device, and an adjustment limiting member for controlling adjustment thereof. In one embodiment, the adjustment mechanism includes a first cam ring rotatable relative to both a pressure plate and a cover, and a second cam ring engaging the first cam ring on a side of the first cam ring opposite the cover and rotatably fixed relative to the cover. The first cam ring is rotatable with respect to the second cam ring such that ramped surfaces cam against each other to increase the axial displacement of the first and second cam rings, whereby the axial displacement compensates for wear on the friction surface. The adjustment limiting device is selectively engagable with the first cam ring to inhibit rotation thereof.Type: GrantFiled: February 19, 2003Date of Patent: December 7, 2004Assignee: Eaton CorporationInventors: John D. Conrad, Roger E. Knueve, Martin E. Kummer, Glen A. Pepple, David L. Rollins, Daniel V. Gochenour

Publication number: 20040055846Abstract: A frictional clutch for a motor vehicle includes a cover, a pressure plate, a biasing member, air adjustment mechanism and an annular shield. The cover has an axis of rotation. The pressure plate is coupled to the cover for rotation therewith about the axis. The pressure plate has a frictional engagement surface substantially normal to the axis. The biasing member is interposed between the cover the pressure plate, and biases the pressure plate toward an engaged pressure plate position. The adjustment mechanism is centered about the axis and is located at a first radial distance from the axis. The adjustment mechanism is operably disposed between the biasing member and one of the pressure plate and the cover. The annular dust shield is disposed radially within the adjustment mechanism. The annular dust shield is axially alignment with the adjustment mechanism. The shield is sized and oriented to protect the adjustment mechanism from debris radiating outward from a central area of the clutch.Type: ApplicationFiled: June 30, 2003Publication date: March 25, 2004Applicant: Eaton CorporationInventors: John D.

Patent number: 6478130Abstract: A clutch button is provided including a friction pad having first and second surfaces. The friction pad has a radial outer and inner edges. The friction pad also has first and second upper outward circumferential edges adjacent to the radial outer edge. The friction pad has first and second lower outward circumferential edges adjacent to the radial inner edge. The friction pad has first and second inward circumferential outer edges joining the respective first and second outward upper and lower circumferential edges. The friction pad has a first groove formed in the first surface extending from the first upper outward circumferential edge to one of the second upper and lower outward circumferential edges. A second groove is formed in the first surface extending from the first lower outward circumferential edge to the other one of the second upper or lower circumferential edges the first groove does not extend to. A backing plate is bonded to the second surface.Type: GrantFiled: December 22, 2000Date of Patent: November 12, 2002Assignee: Eaton CorporationInventors: Roger E. Knueve, John David Conrad, Loren H. Uthoff, Jr.
