Abstract
A one-piece transmission brake band and the method of forming the same whin the band is an elongated strap with brackets at the opposite ends thereof, the brackets providing an apply end and a reaction end. Each end consists of an end portion 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 or spot welding. The apply end of the band has the outer layer provided with a transverse upwardly folded or crimped ridge having a central depression to receive the end of an apply piston, and the reaction end has an outwardly extending radial opening formed by piercing through both layers of material after the end is folded over, with the layers being outwardly extruded in both the radial and circumferential directions. An alternative embodiment utilizes an insert having a cylindrical body with a circumferential base flange. An opening is stamped in the outer layer of material with a raised rim therearound; the opening receiving the cylindrical body and the raised rim receiving the base flange.
