Bremsband für Transmissionsverband.

摘要

A one-piece transmission brake band (10) and the method of forming the same wherein the band is an elongated strap (11) with brackets (14,15) at the opposite ends (12,13) thereof, the brackets providing an apply end and a reaction end. Each end consists of an end portion (12,13) of the strap that is folded over upon itself onto the exterior surface of the band and suitably fastened thereto, such as by clinch fastening (25,34) or spot welding. The apply end of the band has the outer layer (12) provided with a transverse upwardly folded or crimped ridge (20) having a central depression (23) to receive the end of an apply piston (16), and the reaction end has an outwardly extending radial opening (26) formed by piercing through both layers (27,28) of material after the end (13) is folded over, with the layers being outwardly extruded in both the radial and circumferential directions. An alternative embodiment utilizes an insert (42) having a cylindrical body (43) with a circumferential base flange (44). An opening (46) is stamped in the outer layer (45) of material with a raised rim (47) therearound; the opening (46) receiving the cylindrical body (42) and the raised rim (47) receiving the base flange (44).
