Abstract: A brake disc comprising a friction surface which has regions comprising recesses, wherein the recesses can vary in the circumferential direction in such a manner that the recesses are formed and/or are arranged such that the recesses in total in the radial direction do not exert any transverse forces on the brake pad.

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.

Abstract: An arrangement for bearing a non-driven wheel in an automotive vehicle or the like, includes a carrier unit, a wheel hub and an anti-friction bearing.The arrangement provides thatthe wheel hub (1) is integrally formed with a trunnion;a one-piece or bipartite inner ring (2a) of the anti-friction bearing (2) is secured to the trunnion (1a), andan axle body (3) having a bore (3a) for accommodating an outer ring (2b) of the anti-friction bearing (2) is provided as the carrier unit.As the outer ring of the anti-friction bearing is arranged directly in the axle body (3), no screw operation is any longer required for securing the bearing means to the vehicle. As the inner ring is secured to the trunnion (1a) of the wheel hub (1) by roll rivets, there is no need for the otherwise required bearing adjustment during final assembly. The measures according to the invention involve the advantage that the number of components and also the efforts to be taken in the final assembly are decreased.
