  • Patent number: 11796020
    Abstract: A lining carrier (1) for a disc brake has a friction lining (2), and the lining carrier (1) is arranged in a lining carrier shaft (6) of a brake carrier (7). The lining carrier (1) has a front side (3) which faces the friction lining (2), a rear side (4) which faces away from the friction lining (2), and an edge face (5) which extends around a perimeter of the rear side (4) A region (8) of the edge face (5) that faces the lining carrier shaft (6) has a recess (9). A reinforcing rib (10; 10b) is arranged centrally on the recess (9).

  • Patent number: 11384808
    Abstract: The invention relates to a wrap spring for blocking an unwanted rotational movement of a rotary element. The invention further relates to an adjusting device for adjusting the wear of brake pads of a disk brake. An adjusting device comprises a guide sleeve in which a wrap spring is arranged, a grooved ring which encompasses the guide sleeve, wherein the grooved ring is coupled to a closure cap via a torsion spring, and an opening ring encompassing the grooved ring. The invention further relates to a disk brake for a vehicle, in particular for a utility vehicle, wherein the disk brake comprises an adjusting device with a wrap spring.

  • Patent number: 11002327
    Abstract: An adjuster unit (100) for a vehicle disc brake (1), in particular an air disc brake (1) of a commercial vehicle, includes an adjustment spindle (101) adapted to be operatively coupled with one of the brake pads (9) such that by rotation in a first direction, the adjustment spindle (101) moves the brake pad (9) towards the disc (11). By rotation in a second direction opposite of the first direction, the adjustment spindle (101) moves the brake pad away from the disc (11). An actuator ring assembly (107) is rotatable about the adjustment spindle (101); and a wrap spring (109) is helically wound around the adjustment spindle (101). The wrap spring (109), being part of the adjuster unit, is positioned on the adjuster unit, in particular on the adjustment spindle, to engage a stop (117) upon rotation of the adjustment spindle (101) in the second direction, causing the diameter of the wrap spring (109) to increase.

  • Patent number: 10634201
    Abstract: A disk brake includes a brake disc, a brake shaft having a rotation axis that lies parallel to a main plane of the brake disc, a brake pad lying on a same side as the brake shaft relative to the brake disc, a pressure piece disposed between the brake shaft and the brake pad, a first limiting device configured to limit, to a predefined first extent, the displaceability of the pressure piece relative to the brake disc in a direction parallel to the rotation axis of the brake shaft, and a second limiting device configured to limit, to a predefined second extent, the displaceability of the brake shaft relative to the brake disc in a direction parallel to the rotation axis of the brake shaft, the second limiting device comprising a first stop on the pressure piece and a second stop on the brake shaft.
