ELECTROMECHANICALLY ACTUABLE DISK BRAKE FOR MOTOR VEHICLES AND METHOD FOR DETERMINING A BRAKE APPLICATION FORCE

摘要

Electromechanically actuable disk brake for motor vehicles, comprising an actuating unit (40) and a brake caliper (1), wherein the actuating unit (40) comprises a gearbox having a rotatably mounted, rotatorily drivable first gear element (3) and a second gear element (27), the translational motion of which is transmitted to the friction pad (31). An elastic support element (7) having a defined characteristic spring force-spring excursion line is arranged between the first gear element (3) and the brake caliper (1), by means of which line the first gear element (3) is supported on the brake caliper (1), by means of which line a displacement of the first gear element (3) is made possible when applying the brake. A path or position sensor (24, 12, 14) is arranged in the actuating unit (40) and measures a position or displacement of the first gear element (3). The invention further relates to a method for determining a brake application force in an electromechanically actuable disk brake.
