A brake disc, in particular an internally ventilated brake disc, implemented as a casting includes a friction ring having an inner toothed rim and a neck materially separated therefrom and retained against rotation by an outer toothed rim. The neck is connecting to a wheel hub. Cast-in sliding elements are provided between the teeth to allow for a radial displacement of the friction ring relative to the neck. Each sliding element has a U-shape, the opposite legs thereof being disposed between the radially and axially oriented side faces of the associated teeth facing each other, wherein a web connecting the legs extends radially.

A method of forming a pole wheel connected to a wheel hub of a motor vehicle and a corresponding apparatus are described. A magnetically permeable, prefabricated pole wheel is placed in a mold for forming the wheel hub, and the mold is filled with a melt composed of a magnetically impermeable material in the solidified state. The melt fills the apertures formed between adjacent teeth of the pole wheel, while a shape of the pole wheel is substantially maintained.

A roller bearing, particularly for mounting the wheel of a commercial vehicle, has two angular-contact ball bearings placed in an O-arrangement relative to one another. The roller bearing is designed such that each angular-contact ball bearing is associated to a roller body row having a common inner ring with the angular contact ball bearing, wherein the two roller body rows are facing one another and form inner bearing rows.

A pneumatic disc brake for utility vehicles has two brake pad carrier plates to which brake pads are fixed. The disc brake is equipped with an application device which has two pressure plungers. By way of a force-absorbing connection between the pressure plungers and the facing surface of the brake pad carrier plate, a bridge is relieved of bending stresses. The end faces of the pressure plungers and at least the contact faces of the facing brake pad carrier plate are provided with profilings, which engage into one another in a form-fitting manner, such that at least in the event of full-load braking, each brake pad is moved in the peripheral direction.

Control electronics integrated in a brake, preferably a disc brake, are provided in particular for utility vehicles. The disc brake includes a brake caliper covering a brake disc and a brake application device with pneumatic or electromotive actuation, located in the brake caliper and used for applying the brake. The control electronics monitors specific parameters of the brake and regulates braking components and is connected to a power supply. The control electronics is characterized in that it includes at least one transmitter/receiver unit which is in active connection with a sensor external to the brake, pertaining to the wheel or proximate the wheel.

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 brake disc for a vehicle has at least one annular friction surface provided on at least one outer face of the disc to which a brake pad can be applied for braking purposes. The friction surface has a large number of subsegments, at least some of which are physically separated from one another by expansion joints. The brake disc is configured in such a way that the depth of the expansion joints is greater than the permissible rate of wear of the friction surface.

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.
摘要:
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.
