Abstract: In a method for displacing and storing brake fluid for a hydraulic brake system of a vehicle which brake system has at least one hydraulic accumulator, at least one brake booster and at least one brake circuit, the brake booster is configured in such a manner, that even without an action of the driver, actuation of the brake booster allows a volume of brake fluid to be automatically displaced. The brake fluid is displaced into the hydraulic accumulator and stored, by automatic actuation of the brake booster, and at least a portion of the stored brake fluid is emptied by the hydraulic accumulator into the brake circuit as a function of the operating state of the brake system.

Abstract: A method for actuating a hydraulic vehicle brake system, includes a master brake cylinder with a preferably electromechanical brake booster and a wheel slip control device. The master brake cylinder is actuated simultaneously with the brake booster, and hydraulic pumps of the wheel slip control device are driven by an electric motor. Pressure builds more quickly in the wheel brakes of the vehicle brake system for safety and assistance functions that require high pressure build-up dynamic. The method also increases the wheel brake pressure using the pressure that can be generated by actuating the master brake cylinder with the brake booster.

Abstract: A method for operating a hydraulic vehicle braking system that has an anti-lock control unit is disclosed. The system includes a brake master cylinder having an electromechanical brake booster. As the pressure level of the vehicle braking system decreases during an anti-lock control, in which all vehicle wheels are controlled, the boosting force of the brake booster is reduced in an anti-lock control of this type.

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 brake booster with an electric motor and a helical gearing. The brake booster is used for coupling an auxiliary force via a driver into a piston rod. The invention proposes connecting a spindle of the helical gearing elastically via a spring element to the piston rod such that, in the event of rapid actuation of the brake, the helical gearing and a rotor of the electric motor do not have to be accelerated entirely muscle power. The muscle power required for actuating a brake is reduced as a result in the event of a rapid actuation of the brake.

Abstract: A connecting element connects a brake pedal to a brake force amplifier of a vehicle brake system. A helical compression spring as a first spring element and a rubbery-elastic reaction disk as a second spring element are disposed between a pedal rod and a piston rod of the connecting element, the spring elements being installed in series due to the arrangement thereof. Due to the higher spring rate of the reaction disk preferably increasing with load, the connecting element has a progressive spring characteristic line. As soon as the pedal rod contacts the reaction disk the helical compression spring and the reaction disk act in parallel and serially such that the progression of the total spring characteristic line further increases.

Abstract: A method and control device for operating a brake-boosted hydraulic brake system of a vehicle, including ascertaining information relating to an increase or a decrease in an additional braking force exerted on at least one wheel in addition to a hydraulic braking force of the brake system, which increase or decrease is greater than a predefined minimum difference, altering an assistance force to a force introduction element, by a force difference, taking account of the ascertained information, so that the hydraulic braking force is altered to correspond to the increase or decrease in the additional braking force, and displacing a volume of a brake medium of the brake system between at least one accumulator chamber of at least one plunger and/or of at least one two-chamber cylinder and a volume of the brake system outside the accumulator.

Abstract: The invention relates to an electromechanical brake force booster for a hydraulic vehicle brake system. The invention proposes that the brake force booster be formed with two restoring springs, one of which acts on an electromechanical actuator and the other of which restoring springs acts on a pedal rod. In the event of failure of the electromechanical actuator, only the other spring, which preferably has a relatively low spring force, must be compressed using muscle force. The force loss in the event of actuation exclusively by muscle force is reduced.

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 method for operating a hydraulic vehicle braking system having an electromechanical brake booster is disclosed. A shut-off valve that is located between a brake master cylinder and wheel brakes is closed to maintain a wheel-brake pressure and thus a braking force. To maintain a constant braking force, no current must be applied to an electric motor of the brake booster. The vehicle braking system can be used as a parking brake. The shut-off valve is present if the vehicle braking system has an anti-lock control device.

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.
