Method for adjusting clamping force exerted by parking brake, involves moving position of braking piston in lateral direction by rotary movement of spindle, which is carried out by evaluation of position of spindle nut placed on spindle

摘要

The method involves generating a clamping force by an electromotive braking device having an electromechanical actuator. The position of a braking piston (6) is moved in lateral direction by the rotary movement of a spindle (4). The rotary movement of the spindle is carried out by evaluation of the position of a spindle nut (12) placed on the spindle. The information from position detecting units (13,14) are used as trigger criteria for a braking motor (3) for detecting the position of the spindle nut. An independent claim is included for a parking brake for adjusting an exerted clamping force.
