Abstract: A brake unit comprising at least one brake and at least one brake pad having at least one friction lining is described. The brake has a disk brake with a brake rotor made of a ceramic-metal composite (CMC) whose outer surface or surfaces at least partially form a friction surface for the at least one friction lining, and a disk brake cup that is mounted on the disk brake by way of one or more mounting elements. The friction surface of the disk brake has a hardness of approximately 1600 to 2500 HV, and the at least one friction lining has a coefficient of friction of approximately 0.3 to 0.5. The disk brake cup and/or the mounting elements form a corrosion-inhibiting attachment to the disk brake. The brake unit can be operated in corrosion-free fashion over a service life of at least approximately eight to 10 years or approximately 200,000 to 300,000 km.

Abstract: A brake unit has a brake application device, a brake disc with a friction surface and a brake shoe with a friction lining which, during the actuation of the brake unit, acts by an application force Fs of the brake shoe on the friction surface of the brake disc. The friction surface of the brake disc is formed from a ceramic/metal composite material. A control device controls the application force Fs of the brake shoe during a braking procedure such that a defined braking torque results as a function of the application force. The brake shoe application force is increased by an increase in pressure such that an essentially linearly varying braking torque results. The invention also relates to a brake unit for carrying out this method by use of an electrohydraulic control device.

Abstract: A brake unit including a brake disc of a material having a high thermal loading capacity and a brake pad that cooperates with it in tribological fashion. The brake disc is essentially made of a short-fiber reinforced ceramic material, whose thermal conductivity, in particular transversely to the disc surface, is at least 20 W/mK, preferably about 30 to 45 W/mK. The brake disc is combined with a brake pad having an organically bonded matrix. The brake pad may be a conventional series brake pad. The brake unit provides an optimal pairing of a brake disc, having a high thermal loading capacity, with a conventional brake pad in light of a reasonably expected brake pad service life, and in light of other tribological requirements, such as the friction coefficient.

Abstract: A brake unit includes a brake disc of a ceramic material and a brake pad that cooperates with it in tribological fashion. The brake pad is made of a sintered metal material or of an inorganically bound material having a ceramic binding phase and metal particles. The brake unit has a high thermal loading capacity, very good performance characteristics in terms of comfort, and an acceptable service life.

Abstract: In disc brakes, disturbing noises, such as whistling or squealing, occurring during braking operations can be prevented if the brake shoe, to be pressed against a brake disc by a pressure member, for example a hydraulically actuated piston, is taken along in the circumferential direction of the latter as soon as the brake shoe comes into contact with the brake disc, and is laid against bearing faces of a brake anchor plate. Accordingly, the pressure member is provided, on its end face facing the brake shoe, a pressing element which projects beyond the end face, is transversely movable to a limited extent and returns automatically to its initial position again, and which is arranged in the pressure member so as to be axially displaceable counter to a return force which, in the event of mutual contact between the pressing element and brake shoe, is lower than the pressing force of the pressure member.

Abstract: An adjusting device is disclosed for the brake shoes of inside shoe brakes. The adjusting device includes two levers which are articulated on a carrier at a lateral distance from one another. The levers each engage on one of two adjacent brake shoe ends and are jointly in engagement with a frustoconical endpiece of an actuating member guided rotatably on the carrier in a threaded bore provided between the levers and extending in parallel with a brake drum axis. During the rotation of the actuating member for the adjustment of the brake shoes, the two levers are pivoted in directions opposite to one another, being supported respectively on one of two mutually opposite edges of the brake-shoe webs so as to surround these. The adjusting device is merely attached by its levers on to the brake shoe webs so it can also execute self-reinforcing floating movements of the brake shoes in dual servo-brakes.

Abstract: An adjusting device for automatically compensating for cable strand elongation in a vehicle parking brake utilizes a rotatable disc cam having a circumferential edge which spirals radially out to effect a displacement of a cable yoke in a cable tensioning direction as slack develops in a cable strand of the parking brake. The disc cam is tensioned by a torsion spring, the entire device having a small number of parts and high operational reliability even when dirty.
