Abstract:

An improved double-wrap brake band having a bracket member (16) consisting of an apply bracket (20), a reaction bracket (22), and a connector bracket (24) secured to three generally parallel bands (12A, 12B, 12C). The bands (12A, 12B, 12C) include a plurality of position oriented non-circular slots (36) designed to accept corresponding non-circular extruded tabs (44) extending from the bracket member (16). Each of the tabs has a longitudinal curvature that is substantially radially parallel to the annular inner peripheral surface (42) of the bracket member (44) and the annular inner peripheral surface (15) of the strap member (10). The tabs (44), after clinching, serve to retain the bracket member (16) securely on the bands (12A, 12B, 12C).
