Abstract: The invention relates to a brake disk (2) comprising a friction ring (4) and a brake disk hub (6). Both the friction ring (4) and the brake disk hub (6) are provided with a ring land (8, 10) which overlap in a concentric manner. The ring land (8, 10) encompass recesses (14, 16) through which a joining arrangement (12) is guided in the form of a connecting pin (20). Also provided is a support ring (18) which encloses the ring land (8) of the friction ring (4) in a sandwich-type manner along with the ring land (10) of the brake disk hub (6). The support ring (18) comprises recesses (22) within which ends of the connecting pin (20) are supportingly mounted.

Abstract: Composite brake disc, comprising cast iron carrier disc (1) and at least one friction ring (2) of the different material rigidly joined therewith, which covers over essentially the area opposite to the brake pad, wherein the friction ring (2) is comprised of a friction material, which exhibits a higher corrosion resistance than the cast iron carrier disc (1), and process for production of a composite brake disc by joining a cast iron carrier disc (1) with at least one friction ring (2) by friction welding or by casting the carrier disc (1) thereon.

Abstract: A process for producing a fiber-reinforced, ceramic structural component comprising high-temperature resistant fibers which are reaction-bonded to a matrix of silicon carbide comprises the steps of coating bundles of fibers with pyrolysable binder and solidifying the binder, producing mixtures of fiber bundles, fillers and binders, pressing the mixtures to produce a pressed body, pyrolysing the pressed body under the exclusion of oxygen to form a porous, carbon-containing preform, infiltrating the preform with a silicon melt to form the silicon carbide matrix, in which various pressing compounds are produced, which contain fibers of different quality and in different proportions and different coatings. These pressing compounds are arranged at different levels and in different spatial directions in the press mould during the filling of the press mould. After the pressing, the regions produced in this way are retained in the press mould.

Abstract: A method for manufacturing a crankshaft for motor vehicles with passages being provided in the crankshaft for receiving lubricant. Prior to the casting process, place holders, which may include formed parts having cavities alone and/or together with a core, are inserted into the mold to form passages for receiving lubricant.
