Abstract: The invention relates to a hybrid brake system having a hydraulic service brake system and an electromechanical service brake system. According to the invention, a brake booster is designed as a pedal simulator, which can be used to boost power and to generate a pedal power which is counter to the direction of actuation. When the hydraulic service brake system fails, the electromechanical service brake system is used for braking and the brake booster generates a pedal power which allows or facilitates dosage of the brake actuation.

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.

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.

The brake booster is used for coupling an auxiliary force via a driver into a piston rod.

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.
