Problems solved by technology

[0003] The brake linings are subject to wear during running operation, which leads to an extension of the adjustment stroke of the brake piston, so that the duration up to the rated clamping force is increased with increasing wear of the brake linings

Embodiment Construction

[0021] exist figure 1 shows an electromechanical parking brake 1 for holding a motor vehicle at a standstill. The parking brake 1 comprises a brake caliper 2 with a caliper 9 which engages a brake disc 10 . As a control element, the parking brake 1 has an electric motor as a brake motor 3 which rotationally drives a spindle 4 on which a spindle part 5 designed as a spindle nut is rotatably mounted. The spindle part 5 is adjusted axially as the spindle 4 rotates. The spindle part 5 moves inside a brake piston 6 which is the carrier of a brake lining 7 which is pressed by the brake piston 6 against the brake disk 10 . On the opposite side of the brake disk 10 there is a further brake lining 8 , which is held stationary on the caliper 9 .

[0022] Inside the brake piston 6 , the spindle part 5 can be moved axially forwards in the direction of the brake disk 10 during the rotational movement of the spindle 4 or axially backwards during the counterrotational movement of the spin...

Abstract

The invention relates to a method for adjusting a parking brake, and the parking brake comprises an electromechanical brake device with an electric braking motor and for generating electromechanical clamp force. In the method, if a specific running policy is completed from a lastly-implemented tensioning process, the parking brake is automatically tensioned until a rating clamping force is reached and then the parking brake is opened.

Description

technical field [0001] The invention relates to a method for adjusting a parking brake in a motor vehicle according to the preamble of claim 1 . Background technique [0002] DE 103 61 042 B3 describes a parking or parking brake in a motor vehicle, by means of which the motor vehicle is held at a standstill. In this parking brake, the clamping force can be generated electromechanically in that the electric brake motor acts axially in the direction of the brake disc on the brake piston, which is the seat of the brake lining. carrier. [0003] The brake linings are subject to wear during running operation, which leads to an extension of the adjustment stroke of the brake piston, so that the time to reach the rated clamping force increases with increasing wear of the brake linings. Contents of the invention [0004] The object of the invention is to minimize the adjustment time in the parking brake of the motor vehicle. [0005] This object is achieved according to the inv...
