The present invention discloses a brake device for the wheels of an automotive vehicle which includes a wheel-sided brake drum and a vehicle-sided mud guard that engages in a non-contact manner with a circumferential web into an annular recess in the end surface of the brake drum opposite the mud guard in order to provide a labyrinth-type seal. In conventional brake devices, the mud guard along with a welded annular web typically has a two-part design. In contrast thereto, the present invention proposes that the mud guard be punched and deep drawn from sheet metal and that the circumferential web be integrally designed with the mud guard by noncutting shaping.

A seal arrangement is disclosed for an actuating device of a drum brake furnished with an actuating lever which projects through the brake carrier. This arrangement includes an oval pleated bellows (1) fastened by a clamping ring (14) having teeth (15) arranged on its external edge (30) pressed into the wall of a matching, generally elliptical recess. Preferably, the pleated bellows is of asymmetrical configuration and is in a largely unloaded condition in the actuating position of the actuating lever.

Seal for an actuating device for a drum brake

An apparatus for a drum brake for mechanically actuatable self-energizing internal shoe-type drum brakes for automotive vehicles. A pair of brake shoes (4, 5) is arranged on a brake carrier plate (27) at a thrust member (6) and furnished with tension springs (7, 10). A mechanical actuating apparatus acts between a pair of brake shoe ends (4, 5) disposed opposite each other and prestressed by springs (7, 10). The mechanical actuating apparatus presses the brake shoes (4, 5) for braking against a brake drum (1) enclosing them and a first automatically clearance compensating adjusting device is arranged between the brake shoe ends as well as a second adjusting device arranged at at least one brake shoe web (12) supporting the brake shoe (5). In order to provide a constant functioning reliability using simple-design, and a low-cost components, while simultaneously eliminating conventional checking and adjusting operations, the adjusting device is comprised of a first adjusting apparatus with a self-adjusting, variable-length pressure strut (39) arranged between the brake shoes (4, 5) and that a second adjusting apparatus is furnished with a self-adjusting adjustment member at a brake shoe web (12) supporting the brake shoe (5), which adjustment member interacts in circumferential direction both with the mechanical actuating device (3) and with a supporting bracket (2).

An adjusting device for a disc brake comprised of a brake piston which, for the actuation of a brake shoe, is slidably arranged in a brake cylinder and which is actuatable by way of a hydraulic and a mechanical actuating device. Between the brake piston and the mechanical actuating device an adjusting member is provided which is composed of two adjusting elements interconnected by way of a thread without self-locking engagement. The adjusting member comprises a friction clutch having conical friction surfaces for fixation of one of the adjusting elements on mechanical actuation; and includes a spring which is supported on a stop formed fast with the housing and on a roller bearing seated on one of the adjusting elements. For the improved manufacture of the parts and in order to improve and facilitate the assembly, the accommodation sleeve comprises at least one groove extending substantially in the direction of the longitudinal axis of the accommodation sleeve.

Automatic adjusting device for a disc brake

An automatic adjusting device for a disc brake having a brake piston displaceably arranged in a brake cylinder for the purpose of actuation of a brake shoe. This device which is actuatable by means of a hydraulic and a mechanical actuating device, includes an adjusting member between the brake piston and the mechanic actuating device which member is composed of two adjusting elements, an adjusting spindle and adjusting nut interconnected via a thread without self-locking engagement. It further comprises a friction clutch having conical friction surfaces for fixing one of the adjusting elements in position on mechanical actuation. One of the conical friction surfaces is on one of the adjusting elements and the other friction surface is on a mechanically actuatable clamping member. It also comprises a bowl-type (cup-shaped) spring retainer which is secured to the brake housing by means of an accommodation sleeve. In order to render manufacture as simple and cost-effective as possible, the accommodation sleeve is made from a straight tubular member which is pressed into a corresponding bore in the brake housing.

Automatic adjusting device for a disc brake with press fit members

A pin guide and damping bushing for the caliper of a floating-caliper spot-type disc brake which is provided with a brake carrier and a caliper axially slidable relative to the brake carrier and straddling a brake disc and brake shoes. The brake carrier or the caliper is provided with a least one pin which is guided in a bore of the caliper or of the brake carrier. At least one elastic guide element (4) is provided for the pin and inserted in the bore, a stop element (6) which on itself is rigid and limits radial motions of the pin within the bore and which is configured with a base body having a substantially circular cylinder-shaped cross-section and is provided with outwardly extending extensions (26) constituting stop faces. One section of the damping and guide element (4) is arranged in interstices which are formed externally between said extensions.
