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.

A spot-type disc brake for automotive vehicles, with a housing and with a brake carrier provided with two arms which are positioned in radial direction relative to the brake disc at a distance from each other and with a brake lining slidably guided at the arms in the direction of brake application and furnished with a carrier plate. The brake lining is connected to the arms in a positive locking fit in the direction of the circumference of the brake disc in such a manner that the frictional force occurring at the brake lining is transmitted to both arms at least in the presence of more elevated brake application forces. The arms with surfaces facing each other form a guide which is open in radially outward direction and serves to accommodate and guide the brake shoe. One arm in the vicinity of the brake disc is formed with a groove extending in the direction of brake application and is open outwardly. The housing is arranged axially slidably on pins by of pin guides and the housing bridge is supported through the carrier plate. The contour of the brake lining is positioned outside a swinging range of the housing and is swingable about one of the pins.

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).

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.

A support of a floating caliper (7) of a spot-type disc brake on an axially external brake shoe (4) is described. For the support, two carrier elements (5, 6) are disposed spaced apart laterally in the circumferential direction on the external brake shoe (4), the corner elements (5, 6) furnished with projections (8, 9) which engage two axially extending grooves (14, 15) on the inside of circumferential extensions on the floating caliper (7) and which come to be abutted against their internal guide surfaces (16, 17, 18, 19). The caliper is thereby of maximized width and rigidity while being securely supported on the external brake shoe.

The present invention relates to a disc brake with hydraulically operable brake pads and a mechanical actuating which includes an actuating shaft that is rotatably and sealedly mounted in a bore of a brake housing and acts upon at least one of the brake pads. The present invention focuses on that at least in the area of a shaft duct, a sealing element is provided which is fixed to the actuating shaft so as to rotate along with it and cooperates with at least one associated sealing element and/or mating sealing surfaces in a radial direction. The sealing element bridges a portion of the actuating shaft which is different from the shape of a circle.

Resetting of the actuator piston of a disc brake by an adjusting device is enabled by sliding movement of the piston so that a piston position may be reset without any special arrangement for turning an adjusting spindle (5), or by turning the piston itself. The adjusting spindle (5) is released for rotation during resetting, while the adjusting spindle (5) is normally fixed against rotation yet axially slidably during the time of hydraulic actuation and during manual braking.
