Abstract: An expanding device for actuating one of the brake shoes of a drum brake includes a body of revolution and transmission bodies actuated by the body of revolution via ball track ramps. A spacer body is located between two partial bodies of the body of revolution, the spacer body guided by an adjustment spring keeping the partial bodies at the respectively reached distance. The spacer body is screwed onto a pin on the first partial body. A readjustment nut ensures that, when the two partial bodies are pushed apart, the spacer body rotates on the pin and moves away from a supporting surface on a partition of the second partial body. Upon renewed actuation of the brakes, the readjustment nut is guided such that the spacer body bears against the second partial body, but takes up a different position on the pin, the position corresponding to the air clearance readjustment.

Abstract: An expansion device for drum brakes, which is floatingly and approximately centrally arranged between two substantially symmetrical brake shoes, the expansion device including at least two gear levers articulated to each other and each supported on a brake shoe, at least one of the gear levers of the expansion lock being coupled to an actuating element of an actuator system such that the brake shoes carry out an even, translationally directed expanding movement, which is converted by a gearing, in the direction of the brake drum. At least one of the gear levers of the spreader lock has a spring element integrated into it that can be elastically reversibly deformed by a brake application force about a defined elasticity ?S of at least 1 mm in a defined manner.

Abstract: A drum brake module for motor vehicles, the drum brake module being driven by an electric motor and having at least one parking brake function, includes an electromechanical cable pull actuator which is fastened on the anchor plate with the aid of an adapter. The adapter is designed as a one-piece, thin walled frame having at least one fastening flange for receiving the cable pull actuator and is held in place on the anchor plate.

Abstract: A disc brake includes brake pads (7), which are slidably received on either side of a brake disc within guide portions (6) of the disc brake, and including a spring arrangement (10) for spring cushioning the brake pads (7). Disc brakes of this type are frequently used in motor vehicles. To improve the spring cushioning of the brake pads, the spring arrangement (10) is equipped with at least one radial spring element (11) for radially clamping the brake pads (7) with respect to the guide portions (6), at least one axial spring element (22) for axially clamping the brake pads (7) in relation to each other, and at least one tangential spring element (18) for tangentially clamping the brake pads (7) in relation to the guide portions (6). The three spring elements (11, 18, 22) act in different spatial dimensions and can be embodied as separate components which are independent of each other.

Abstract: A drum brake module for motor vehicles operable by electric motor and performs at least one parking brake function, having an electromechanical actuator mounted on one side of the armature plate and a rotational-translational movement converter converting a rotational drive rotational movement into a translational activation movement of brake shoes arranged on a side of the armature plate facing away from the actuator in a brake drum, and including at least one supporting device between the brake shoes such that the latter can carry out an activation movement in the direction of the brake drum. A drive nut is supported by the rotational-translational movement converter in an axially secure and rotatable fashion on the armature plate to assist the braking force. The drive nut drives a spindle arrangement mounted in a rotationally fixed and axially displaceable fashion and engages with an activation cable on at least one brake shoe.

Abstract: A partially lined disk brake includes a brake anchor plate, mountable on which are two brake linings, which are arranged at a distance from one another and which between them are capable of receiving a brake disk capable of rotating about an axis of rotation, wherein an application movement serves to bring the two brake linings into engagement with a friction surface of the brake disk, including a brake caliper, which is arranged on the brake anchor plate and which engages at least partially over the brake linings and the brake disk, and which in the direction of movement of the brake linings can be displaced by an actuating device in relation to the brake anchor plate, wherein the actuating device produces the application movement of the brake linings, and having at least one spring element, which moves the brake linings away from one another again after an application movement.

Abstract: A disk brake having a brake disk, a brake caliper including a bracket, a caliper housing and a brake lining. The bracket and the caliper housing engage axially around the brake disk, with the caliper housing and the brake lining movable in an axial direction. The caliper housing has outer housing limb comprising two housing fingers which run substantially in a radial direction and which span a limb window situated between them and which is open in the direction of the rotational axis, with the housing fingers having one end section facing the rotational axis. A protective screen covers end sections of the housing fingers and conceals a section of the limb window that faces the rotational axis, with an outer dimension of the protective screen in a circumferential direction such that a transition between the protective screen and the housing fingers is substantially stepless in an axial projection.
