摘要:
A parking brake for a commercial vehicle equipped with an air-operated service brake is configured in such a way that the actuating energy for the brake is reduced in comparison to a configuration with a spring brake cylinder, while the installation space in the wheel area is minimized. Primary functional parts of the parking brake include an inner race and an outer race, which delimit an annular gap. Displaceable tapered-roller bearings are located in the annular gap. To adopt a release position in opposition to the action of a compression spring, the tapered roller bearings are disengaged from the conical surfaces of the inner race and the outer race.

A disc brake, particularly for commercial vehicles, is provided having a caliper reaching over a brake disc, a brake application device arranged in the caliper for applying the brake, as well as an adjusting system arranged in the caliper for compensating brake pad and/or disc wear by adjusting the distance between the brake pad and the brake disc. The caliper has a two-part construction including an application-side caliper part and a reaction-side caliper part. The reaction-side caliper part is designed such that it frames the brake disc in its upper circumferential area. The adjusting system has at least one or more adjusting devices also arranged on the reaction side of the brake disc, and preferably on each side of the brake disc.

A disc brake, especially for utility vehicles, which includes a caliper enclosing a brake disc, a pneumatically or electromotively operated tensioning device for tensioning the brake, which is located in the caliper, a magnet wheel rotating with the brake disc, and a stationary sensor for detecting the angle of rotation and the speed of the magnet wheel. The sensor is mounted at a distance from the magnet wheel and at least one line is connected to transmit pulses between the sensor and the magnet wheel. As a result, the sensor can be mounted on the housing protected from the action of heat and other environmental influences and so as to be easily accessible.

A method for controlling an electronically commutated DC motor is provided, the DC motor including at least one particularly permanent magnetic rotor and a wound stator, which is a drive motor for an adjuster device on a pneumatically operated disc brake. The rotor position is determined from electrically measured parameters without sensing of the rotor position. The invention is characterized in that two determination methods for determining the rotor position from electrically measured parameters are combined with each other, whereby one is an inductive measurement and a further one of the determination methods is a measurement of the inducted voltage.

The invention relates to a control method for controlling a resetting system of a disc brake provided with a brake caliper, involving the following steps: 1. in order to determine the actual play of the disc brake, the brake disc is displaced back and forth with the resetting devices located on each side of the brake disc between two axial stops that delimit the displacement path of the brake disc, and the covered actual displacement path is determined; 2. the actual play is calculated and adjusted based on a comparison of the actual displacement path with a pre-stored displacement path calibration value and with a set play. The invention also relates to a brake disc assembly provided with a brake disc that, when mounted on the cams of the hub, can be displaced between stops.

Disclosed is a brake device, particularly a disc brake, comprising a caliper, brake drum, or similar, and energy accumulator, especially an accumulator spring. The energy accumulator rests on the caliper or similar while being supported on an abutment by means of a lever arm. A mechanism for transmitting resilient forces between the energy accumulator embodying one spring element is created with the aid of a lever arm via the abutment. The brake device is characterized in that the lever arms can take at least two or more different angular positions relative to each other in relation to the abutment.

A method for determining the friction value of a disk brake, in particular of self-energizing disk brakes, in which the friction value is determined on the basis of the: motor current for the application direction and retraction direction, idle current I0, wedge angle α, transmission constant K, and clamping force.
摘要:
A disc brake for a utility vehicle, having a brake caliper which encompasses a brake disc and which is fastened, so as to be axially movable in relation to the brake disc, to a positionally fixed brake carrier by means of two fastening elements, wherein the fastening elements have in each case one guide bar which is fixedly connected to the brake carrier, of which guide bars, for the axial mobility of the brake caliper, one in guided in a plain bearing which is designed as a fixed bearing and the other is guided in a plain bearing which is designed as a floating bearing, wherein at least the floating bearing has a guide sleeve, which engages around the guide bar and which is connected to the brake caliper so as to be fixed in terms of movement, with an elastomer bearing sleeve, and the guide bar is covered, on its end side facing away from the brake disc, by means of a cap, is designed such that the cap, while covering the guide sleeve at the end side, is fastened at least in one axial partial region to the elastomer bearing sleeve.

A self-energizing disc brake having an electric actuator in which an activation force applied to the actuator is amplified using a self-energizing device arranged between the actuator and brake lining is described. The device has a brake application unit for applying at least one brake lining to one side of a brake disc by carrying out an application movement of the brake lining relative to the brake disc, the application movement having at least a first movement component in a direction parallel to a rotational axis of the brake disc and a second movement component in a direction tangential to the rotational axis of the brake disc. The device also has at least one electromotive drive for activating the brake application unit.
