Abstract: The invention relates to an electromechanical, self-boosting friction brake, in particular a disk brake. The friction brake is embodied with a wedge element for exerting contact pressure on a friction brake lining; a wedge angle (?) is selected such that a brake parameter C* is located at or near a pole point. As a result, a high self-boosting that tends toward infinity and consequently a low actuating force are attained. To avoid blocking of the friction brake, an actuating device is embodied to block an independent motion of the wedge element, or has a regulating device for regulating a contact pressure of the friction brake lining against a brake body (brake disk).

Abstract: An electromechanically actuatable self-boosting disk brake in which a friction brake lining is guided displaceably with a guide whose angle to the brake disk is adjustable via an electric motor to attain brake reinforcement. The angle of the guide is adjusted independently of an actuating device with which the friction brake lining is pressed against the brake disk.

Abstract: The invention relates to a friction brake (10) for a motor vehicle. The friction brake (10) for instance has a disk brake (12), which is actuatable by means of an actuating device, for instance in the form of a ball thread drive (22). The invention proposes embodying the friction brake (10) with a band brake (34), whose band (36) is mounted on the circumference of a nut (26) of the ball thread drive (22). If the brake band (36) is put under tensile stress in order to actuate the band brake (34), then the brake band (36) rotates the nut (26) of the ball thread drive (22) in a tensing direction and in this way actuates the disk brake (12). The invention has the advantage that the friction brake (10) has high brake boosting and therefore requires only little actuating energy. It is accordingly suitable for embodiment as an electromechanical friction brake (10) with an electric motor (56) for its actuation.

Abstract: The invention relates to an electromechanical disk brake (10). To attain brake boosting, the invention proposes embodying the disk brake (10) with a multiple brake cylinder (24), which is displaceable in a secant direction of a brake disk (20), and which has both a friction brake lining piston (22), which is displaceable transversely to the brake disk (20), and two brake booster pistons (26), disposed facing one another, which are displaceable parallel to the brake disk (20), and which are braced on fixed abutments (36), for instance on an inside of a brake caliper (12) of the disk brake (10). For actuation of the disk brake (10), the multiple brake cylinder (24) is displaced in the direction of rotation (46) of the brake disk (20), and as a result, the brake booster piston (26) that is at the front in the displacement direction moves into the brake cylinder (26) and, via the friction brake lining piston (22), presses the friction brake lining (18) against the brake disk (20).

Abstract: A wheel brake device, which in particular is actuatable electromechanically, for a motor vehicle, includes a pivotable lever, one end of which is engaged by an energy-storing spring element and which with its other end presses against a wheel brake lining. The lever is pivotably supported by a support means that is displaceable in the longitudinal direction of the lever. By displacement of the support means in the longitudinal direction of the lever, a lever arm with which the energy-storing spring element engages the lever lengthens, and a lever arm with which the lever presses against the wheel brake lining shortens. A pressure force with which the energy-storing spring element, via the lever, presses the wheel brake lining against a brake disk can be adjusted by displacement of the support means.

Abstract: The invention relates to an electromechanically actuatable disk brake (10). To attain brake reinforcement, the invention proposes that a friction brake lining (40) be guided displaceably with a guide (44, 50) whose angle to the brake disk (14) is adjustable. A frictional force exerted by the rotating brake disk (14) on the friction brake lining (40) pressed against it causes a force component in the direction of the guide (44, 50), which when the guide (44, 50) is positioned obliquely creates a pressure force of the friction brake lining (40) against the brake disk (14) and thus a brake reinforcement.

An additional signal is determined independently of the output signal, this signal also representing the motion of the vehicle. An arrangement is provided for analyzing the characteristic of the output signal, which depends on the longitudinal velocity of the vehicle, and the characteristic of the additional signal, which also depends on the longitudinal velocity of the vehicle, in order to determine the offset value.

Abstract: The invention relates to a drum brake device (10), which is provided as a wheel brake for a motor vehicle. The invention proposes embodying the drum brake device (10) with a brake belt (14), which is disposed inside a brake drum (12) and can flex in the radial direction of the brake drum (12). Thrust exerted on one end (18) of the brake belt (14) with a simultaneous bracing of the other end (20) of the brake belt (14) causes the brake belt (14) to be pressed against the brake drum (12) from the inside and produces a braking moment. The invention has the advantage that a friction force exerted on the brake belt (14) by the brake drum (12) augments the thrust on the end (18) of the brake belt (14) and thus boosts the braking moment. Another advantage is that the brake belt (14) always rests uniformly against the brake drum (12) over its entire circumference, even, for example, when the brake drum (12) expands due to heating.

Abstract: An electromechanical wheel brake device for a motor vehicle, having an electric motor for driving two planetary gears, connected in series with one another, which actuate the wheel brake device via a threaded roller gear. The planetary gear is provided with a first electromagnetic coupling, with which a sun wheel of the second planetary gear can be locked, or can be connected in a manner fixed against relative rotation to a sun wheel of the first planetary gear, and with a second electromagnetic coupling, with which a ring gear of the second planetary gear can be stopped or can be connected in a manner fixed against relative rotation to a ring gear of the first planetary gear. By means of the electric motor, by switching of the two couplings, the rolling thread drive can be driven fast to overcome an air gap, slowly and with major speed reduction for the ensuing exertion of a high braking force, and fast for releasing without a reversal of the direction of rotation of the electric motor.

Abstract: The invention relates to a braking apparatus having an electric service motor, which serves to actuate a brake via an actuating device. To enable adjusting an air clearance, the invention sets forth a helical gear and a load moment block, which blocks the helical gear against adjusting itself independently and allows adjustment by means of a readjusting motor. To adjust or establish the air clearance, the brake is actuated with the readjusting motor, until a brake lining contacts a brake body, such as a brake disk, and then moves backward by a defined distance. If the service motor and/or the actuating device fails, the braking apparatus can be released with the readjusting motor. In order to achieve a parking brake function, the invention sets forth a second load moment block for the actuating device.
