Abstract
A constricting clutch brake element (10) is operative to selectively transmit mechanical power between relatively movable rotating members. A plurality of backing plates (38) releasibly engage a plurality of friction linings (34). The friction linings are selectively moved radially to operatively engage annular body (12) and a central rotating member (26). The friction linings are releasibly engaged with corresponding backing plates (38) through interengaging ear portions (52) of the lining and slots (62) of the backing plates.
Claims26
Apparatus comprising:
- a friction lining configured for removable engagement with a constricting clutch brake element,
- wherein the clutch brake element includes
- a generally annular body,
- a backing plate movably mounted in operative connection with the body, wherein the backing plate is movable in a radial direction relative to the body,
- wherein the friction lining includes,
- a lining plate,
- a friction pad in operative supported engagement with the lining plate,
- wherein the friction pad includes a wear surface, wherein the wear surface is generally opposed of an area of engagement of the friction pad and the lining plate,
- a pair of ear portions, wherein each ear portion is in operative supported connection with the lining plate and extends generally parallel of the wear surface,
- wherein at least one ear portion includes at least one spring portion,
- wherein each ear portion is configured to releasably slidingly engage a corresponding slot of the backing plate, wherein each slot extends generally perpendicular of the radial direction,
- wherein the slot configured to slidingly engage the at least one ear portion that includes the at least one spring portion, is bounded by a wall,
