Part-lining disc brake

摘要

The invention relates to a part-lining disc brake with two interconnected brake discs 3, 3a, between which the brake carrier 4, the brake linings 8, the actuating device and the brake cylinder 19 together with the piston 20 and piston rod 21 are arranged. The brake is applied by means of a brake cylinder 19 which is connected to the brake carrier 4 and the piston rod 21 of which acts on the outer ring 13, the freewheel 14 and the adjusting ring 10, the flat thread 11, 11a of which acts on the pressure support 12 and the brake plates 7 together with the brake lining 8 on the brake discs 3, 3a. Resetting and adjustment take place via a spring 16 which is engaged into the notched toothing 15 of the adjusting ring 10. The piston travel corresponds to the easing play DELTA L of the brake. When wear occurs on the brake, the rotation of the adjusting ring 10 becomes greater than the easing play DELTA L and the spring 16 engages in the next notched tooth 15. <IMAGE>
