A steering knuckle of a utility vehicle, composed of a cast material, has a main body, a steering knuckle bearing, a hub-type, cup-shaped receiving portion, open towards a rim of a vehicle wheel and suitable for receiving an anti-friction bearing and a bearing journal, and a pad-receiving portion for receiving a brake pad. The pad receiving portion has a support and two supporting elements provided one behind the other in the rotational direction of the vehicle wheel. A control arm attachment for linking an axle guide is formed on the main body.

A method adjusts the slack of a brake assembly having a brake disc, a brake pad, an actuator with an output shaft driven in a forward direction to bring the brake pad and brake disc into frictional engagement defining a braking position and a reverse direction to disengage the brake pad and brake disc and to move the brake pad into a rest position, and a slack adjuster for adjusting a predetermined axial slack distance between the brake pad and the brake disc. The brake pad is moved from the rest position in the reverse direction into a predetermined reference position, and an adjustment of the axial slack distance between the brake pad and brake disc is initiated.

Method for adjusting the slack of a brake assembly and brake assembly

A brake assembly includes a brake disc in rotational engagement with a wheel of a vehicle, a brake pad which frictionally engages the brake disc in a dynamic braking operation and a parking brake operation, a dynamic actuator adapted to bring the brake pad and brake disc into the frictional engagement in the dynamic braking operation, and a parking brake actuator associated with the dynamic actuator such that, in the parking brake operation, the frictional engagement of the brake disc and brake pad is maintained.

Brake assembly and method for controlling a brake assembly

An axle end assembly has a wheel brake arrangement and a wheel hub arrangement. The assembly is designed as a preassembled unit with a hollow shaft element on which the wheel brake arrangement and the wheel hub arrangement are disposed.

An electric-wear adjusting device of a motor vehicle disc brake is provided for adjusting friction surface wear on the brake linings and brake disc of the disc brake having. having a brake application device, preferably with a rotary brake lever. The adjusting device includes an electric motor, a gear mechanism, and an output element. The output element is connected rotationally fixed to a clamping sleeve. The clamping sleeve has inwardly projecting longitudinal ribs on an inner side configured to cooperate with axial grooves of a threaded plunger of a wear-adjuster spindle unit. Also provided is a corresponding disc brake having the electric wear-adjusting device, and a method for measuring and setting air play and measuring wear of a disc brake having the electric wear-adjusting device.

A disc brake, particularly for a commercial vehicle, includes a brake caliper configured as a sliding caliper, two brake pads, which are disposed in the brake caliper, at least one guide spar for fastening the brake caliper to a stationary carrier, a brake application device, effective via at least one adjusting spindle, an adjusting device, which is non-rotatably connected to the adjusting spindle, for compensating brake pad wear, and a restoring device, disposed on the action side and having a restoring element that is elastically deformable if the brake caliper is displaced as a function of the braking operation and by which the caliper can be automatically brought into a starting position. The disc brake is configured such that the restoring device has a supporting part, which remains in position relative to the brake anchor plate if the brake caliper is displaced as a function of the braking operation, and which interacts with the resilient restoring element.

A self-energizing disc brake includes a brake caliper held on a fixed brake carrier, an active-side and a reaction-side brake pad, which may be pressed against a brake disc, an actuating device with a self-energizing device and an adjuster device for compensating pad and/or disc wear. The self-energizing device has at least one pressure ram, in contact on the front face with the active-side pad by way of a split bearing and fixed by the end thereof facing the brake pad to a guide plate movably held in the brake carrier, designed such that the split bearing is enclosed by a seal arrangement when the self-energizing device is in a non-functioning state.

A pneumatic disc brake has a caliper which straddles a brake disc, brake pads pressable against the brake disc, wherein a brake-application-side brake pad can be actuated by a brake lever of a brake application device pivotable about an eccentric axis. Against the end side, the brake lever bears a brake ram which is coupled at the other side to the brake pad or to a guide plate coupled thereto. Two pressure rams are aligned in the same direction and spaced apart from the brake ram. The pressure rams are connected in each case to the caliper and to the brake pad or to the guide plate and have a self-energizing device. The caliper has spherical-cap-shaped bearing receptacles in which rest corresponding plain bearing elements, by which the brake lever, and the pressure rams are supported on the caliper.

Pneumatically actuable disc brake

A hydraulic disc brake includes at least one brake piston that acts upon a brake pad and a parking brake mechanism. A return piston is accommodated in a piston head having a recess. The piston head faces the brake pad.

A method is provided for actuating a wet multiple disc brake, running with cooling oil, especially for a road vehicle. Stationary and rotating radially oriented discs are pressed against one another during braking while overcoming a clearance. The method is characterized in that once the brake is released, the discs associated with each other are separated from each other to such an extent as to form an oil-free or substantially oil-free clearance, wherein the clearance is minimized prior to braking by advancing the discs towards each another.

A pneumatic disc brake includes a caliper which straddles a brake disc, brake pads pressable against the brake disc and a rotary lever actuated brake application device, and a self-energizing mechanism. The brake lever is pivotable about an eccentric axis by a brake cylinder plunger. A self-energizing factor is selected to ensure that the brake automatically releases after braking events. The brake lever is supported on a spherical bearing element mounted to the caliper and forming the eccentric axis. The brake lever bears against a bearing ball which is arranged above the bearing element in the direction of the plunger engagement point, which bearing ball is positioned in a brake ram coupled to the brake pad.
