A floating-frame spot-type disc brake is described comprising a floating frame (1) guided in a manner axially displaceable on a brake carrier (12), and being furnished with two brake cylinders (2, 3) and two brake pistons (4, 5) directly acting on two axially inwardly disposed brake shoes (6, 7). The brake carrier (12) is located entirely on one side of the brake disc and no portion extends across the outer edge of the brake disc (15), so that the maximum diameter of the brake disc is limited only by the relatively thin sections of the floating frame (1) extending across the outer edge of the brake disc. Additional brake shoes (8, 9, 22), on the axially outer side, are fixed to the floating frame (1), in turn transmitting the circumferential force acting on the outer shoes occurring during braking, through a bolt guide (10), into the brake carrier (12).

The invention is related to a spot-type disc brake with a stationary brake carrier (19) at which a floating caliper (1) is slidingly guided which straddles the edge of a brake disc (10), with two brake cylinders (11, 12) which are positioned on the internal axial side of the brake disc (10) aside each other and whose brake pistons (13, 14) act on the brake shoes (5, 7) which are arranged on the same axial side and in circumferential direction of the brake disc (10) at a distance from each other. According to the invention a third brake shoe (6) is fixed on the external axial side of the brake disc (10) to the floating caliper (1), which brake shoe is positioned staggered in such a manner that its friction area point of gravity (36) comes to be arranged substantially between the other two brake shoes (5, 7) in the circumferential direction of the brake disc (10). Braking noises and brake rubbing are eliminated by this arrangement. Further advantages of the inventive brake are constituted by its ease of serviceability in view of an ease of mounting of the brake shoes (5, 6, 7) and by its floating caliper (1) which allows to be manufactured with ease and at but low cost and with but little material, and which simultaneously with a low weight affords an elevated stiffness and a large brake disc diameter.

Floating caliper and brake shoe for spot-type disc brakes

An automatic one-shot adjusting apparatus which is applicable both for mechanically and for hydraulically actuatable duo-servo drum, brakes and which includes two ratchets (6, 14) interacting through springs (11, 15) and is capable of adjusting only upon the release of the brake.

Automatic adjusting apparatus for a duo-servo drum brake

An actuating apparatus is provided for use in a disc brake. The disc brake includes a brake piston slidably accommodated in a brake cylinder. A mechanically actuatable brake lever is non-rotatably coupled to an actuating shaft. The actuating shaft is rotatably accommodated in a bore in a brake cylinder housing. A thrust member is positioned between the actuating shaft and the piston or a further actuating element. A spring preloads the brake lever in the direction of rotation toward a final position. To create an actuating apparatus easy to set-up and mount, the spring also urges the actuating shaft in an axial direction against a stop or a support.
