Brake mechanism of a disk brake and method of controlling intensification of force thereof

摘要

The present invention concerns a brake mechanism of a disc brake received in a caliper (16) and a method for controlling the force amplification for the brake mechanism. The brake mechanism comprises a lever (26, 31) actuated by a brake actuator. The lever is acting on a cross bar (34, 37) by means of an intermediate part (27). The lever (26, 31) and the intermediate part (27) have a line of contact moving along a circular arc during an application stroke of the brake mechanism. The cross bar (34, 37) of the brake mechanism is closely guided and is only moveable in the thrust direction and in the tangential direction of the brake disc. The force amplification of the brake mechanism is adapted to the force characteristics of the brake actuator.
