International Classification:

F16D 4107

US Classification:

192 451

Abstract:

A sprag and roller one-way clutch assembly (10) including an outer cage (12), an inner cage (14) and a ribbon spring (16) for use with a clutch having outer and inner races (70, 72). The outer and inner cages (12, 14) each defines a plurality of corresponding sprag and roller openings (20, 30, 22, 32). The ribbon spring (16) defines a plurality of corresponding sprag and roller windows (40, 42). A plurality of spaced sprags (50) extends between and through the corresponding sprag openings (20, 30) defined by the outer and inner cages (12, 14) and through the corresponding sprag windows (40, 42) defined by the ribbon spring (16). A plurality of spaced rollers (60) extends between the corresponding roller openings (22, 32) defined by the outer and inner cages (12, 14) and through the corresponding roller windows (42) defined by the ribbon spring (16). Each of the rollers (60) has a substantially cylindrical configuration. The rollers (60) act as bearings to support the outer and inner races (70, 72) of the clutch during rotation.

Abstract:

A method for making a friction plate that includes a core plate and a friction facing is disclosed. The method includes cutting a pattern of friction material segments into a friction material sheet such that each friction material segment remains integrally connected to the friction material sheet, locating a predetermined number of the friction material segments adjacent to a surface of a core plate to which a bonding material is present, separating the friction material segments from the friction material sheet, and placing the friction material segments onto the surface of the core plate over the bonding material. An apparatus for practicing this method is also disclosed.
