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 a device which, when a pneumatic and/or hydraulic or electromechanical braking system of a vehicle is controlled, make it possible to set a second braking force on at least one wheel brake of one wheel in a defined manner in addition to the defined setting of a first braking force. The first braking force is generated by a first control unit using first hydraulic and/or pneumatic components, whereas the second braking force is generated at predefinable times as a function of the filling of an accumulator with a pressurized medium. The accumulator is a device separated from the first hydraulic and/or pneumatic components which is preferably mounted in the proximity of the wheel brakes and which is filled via a relative movement between at least one wheel and the vehicle body. It is therefore conceivable that, with the aid of a working cylinder attached to a wheel, the accumulator is filled with volume of a medium by utilizing the relative movement between wheel and body.
