Abstract: The present invention relates to a self-amplifying electromechanical partial lining disc brake, having a ramp mechanism as a self-amplification device. According to the invention, a rack for driving a friction brake pad is situated between roller elements of the ramp mechanism, particularly at a geometrical centroid of an imaginary surface defined by the roller elements. As a result a load is distributed to the roller elements in a more uniform fashion and the pressing force of the friction brake pad against a brake disc when the partial lining disc brake is actuated is distributed more uniformly and counteracts irregular pad wear.

Abstract: The invention relates to an electromechanical friction brake, for example in the form of a disc brake having an electromechanical actuation device. The electric motor of the actuation device presses a frictional brake lining against a brake disc by means of a reduction gearbox and a ball ramp mechanism. The actuation device is supported by a spring washer that is pretensioned so strongly that when the disc brake is released it acts on a segment with a falling spring characteristic; that is, a spring force exerted by the spring washer on the frictional brake lining increases with increasing tension of the disc brake.

Abstract: A retaining bolt for attaching a brake caliper to a support is attached. The retaining bolt is hollow and includes a retaining element which is fixed on one side in a cavity of the retaining bolt, supporting a permanent magnet on a free end. When the retaining bolt is moved due to an external load, the permanent magnet moves in the cavity of the retaining bolt and the modification of the magnetic field thus produced can be measured by a magnetic sensor. The retaining bolt allows the braking power of the disk brake to be measured.

Abstract: A brake system for a motor vehicle and a related method includes a hydraulic service brake system, having a brake booster and is operable via a brake operating element, an electric machine, operable as a generator to brake the motor vehicle, and an electromechanical braking device. A setpoint braking torque is determined as a function of a brake pedal travel. The hydraulic service brake system has an idle travel between the brake operating element and a master brake cylinder, in which no braking torque is generated by the vehicle brake system. In the range of the idle travel, the setpoint braking torque is generated by the generator and/or the electromechanical braking device, and a portion of the electromechanical braking device in the setpoint braking torque is modulated as a function of a portion of the generator in the setpoint braking torque so that variations of the generator portion are compensated.

The rotor and stator can be swiveled in relation to each other when a coil is supplied with current. Due to a symmetric design, the freewheeling mechanism is advantageously insensitive to acceleration forces.

Moreover, the positional tolerances of the freewheel in relation to the motor shaft can be reduced with the aid of the invention.

Abstract: A self-boosting electromechanical friction brake for a motor vehicle in which, with an electromechanical actuator, a friction brake lining can be pressed against a brake disk, and the friction brake lining is braced in the brake caliper via a wedge mechanism, which effects a self boosting. A friction brake lining which is pressed by the actuator has with a lower coefficient of friction, and in particular with less relative fluctuation in the coefficient of friction, than another friction brake lining positioned fixedly in the brake caliper. An operation-dictated fluctuation in the coefficient of friction and thus a change in the self boosting is reduced, and as a result the disk brake, with a low coefficient of friction, can be actuated with less actuation force and less actuation energy.

The widening of the brake caliper is a measurement for the clamping force when the brake disk is actuated.
