Abstract
An integral block for non-driven and non-steerable wheels of an automotive vehicle includes a brake drum, a wheel hub, an antifriction bearing, an axle journal, and an assembly base for non-rotating components of a drum brake. The latter include brake shoes and appertaining mounting means, as well as brake cylinders, brake pistons and parts for connection to brake shoes. An assembly base made by die-casing or forging is formed as a carrier plate having an integrally molded stop for supporting the brake shoes in a circumferential direction, and either a separate, thin-walled mud plate is provided or an integrated mud ring. As opposed to conventional component groups, in which the mounting base is a plate section, the integral block of the invention can more reliably take into account varying load requirements, thereby achieving substantial reductions in weight and manufacturing costs.
