Abstract
An asbestos-free clutch plate assembly has a reduced break-in phase and a facing which is substantially uniformly supported by the clutch plate. The assembly comprises a clutch plate defining a first surface and having a plurality of cambered portions. A substantially rigid, wear resistant, asbestos-free facing is attached to the first surface. The clutch facing has a plurality of grooves formed therein with each groove located substantially along the peak of one of the cambered portions thereby reducing the amount of material to be worn away during the break-in phase. The grooves further enable the clutch facing to conform to the contour of the surface so as to be substantially uniformly supported thereby.
Claims11
An asbestos-free clutch plate assembly having a reduced break-in phase and wherein the clutch facing is substantially uniformly supported by the clutch plate, said assembly comprising:
- a clutch plate defining a first surface having a plurality of cambered portions, each cambered portion defining a peak;
- and
- a substantially rigid, wear resistant, asbestos-free clutch facing attached to said first surface, said clutch facing having a plurality of grooves formed therein with each groove located substantially along the peak of one of said cambered portions thereby reducing the break-in-phase, said grooves further enabling said clutch facing to confrom to the contour of said surface so as to be substantially uniformly supported thereby.
An asbestos-free clutch plate assembly having a reduced break-in phase and wherein the clutch facing is substantially uniformly supported by the clutch plate, said assembly comprising:
- a clutch plate defining a first surface having a plurality of cambered portions, each cambered portion defining a peak;
- and
- a substantially rigid, wear resistant, asbestos-free clutch facing attached to said first surface, said clutch facing having the form of an annular disc defining an outside edge and an inside edge, said clutch facing having a plurality of grooves formed therein with each groove located substantially along the peak of one of said cambered portions thereby reducing the break-in phase, said grooves further enabling said clutch facing to conform to the contour of said surface so as to be substantially uniformly supported thereby,
- and wherein certain of said plurality of grooves extended over a distance less than the distance between said outside edge and said inside edge and being centered about the midpoint between said outside edge and said inside edge thereby increasing the burst strength of said clutch facing.
