  • Patent number: 9933028
    Abstract: A caliper disc brake of a vehicle has a brake disc with an axis of rotation, a brake caliper, a brake anchor plate, a force transmission element, such asa lining support and/or a pressure plate, a holding-down spring for holding down the force transmission element, and a holding-down device (36) which is held and supported on the caliper by a holding device, which pretensions the holding-down spring adially against the force transmission device and tangentially in the direction of rotation against the force transmission device during forwards travel. The holding device has a center line parallel to the axis of rotation. The tangential pre-tensioning is at least partially due to the dimensions (V1, V2) of the holding-down device in the tangential direction from the center line (M) being larger on the disc exit side than on the disc entry side.

  • Patent number: 9816575
    Abstract: A caliper disk brake of a vehicle with a brake disk, a brake caliper, a brake anchor plate, a force transmission element guided and supported in a shaft of the brake caliper or of the brake anchor plate, a holding-down spring for holding down the force transmission element, and a holding-down device held and supported on the caliper by a holding device, pretensions the holding-down spring radially against the force transmission device and pretensions the holding-down spring tangentially in the direction of rotation against the force transmission device during forwards travel. The holding device has a center line parallel to the axis of rotation of the brake disk. The tangential pre-tensioning is at least partially attributed to the dimensions of the holding-down device, as measured in the tangential direction from the center line, being larger at least in sections on the disk exit side than on the disk entry side.

  • Patent number: 6619440
    Abstract: A brake includes a rotating element and a magnet wheel mounted on the rotating element so as to rotate with the rotating element about an axis of rotation. The magnet wheel has a first side extending transversely of the axis of rotation and facing the rotating element and a second side extending transversely of the axis of rotation and facing away from the rotating element. A first axial stop interacts with a first stop section located on the first side of the magnet wheel and a second axial stop interacts with a second stop section located on the second side of the magnet wheel for limiting an axial movement of the magnet wheel relative to the rotating element to a first predetermined amount. Along each line extending parallel to the axis of rotation and extending through the first or the second axial stop, the distance between the first stop section and the second stop section is smaller than the distance between the first axial stop and the second axial stop.

  • Patent number: 5848673
    Abstract: A wear monitoring apparatus for a disc brake, particularly a sliding caliper disc brake, is described. The disc brake has a sliding thrust piece which receives an application force exerted by an application mechanism, and a longitudinally adjustable transmission mechanism for transmitting the application force from the sliding thrust piece to a brake pad. Longitudinal adjustment of the transmission mechanism is a function of the extent of frictional wear of the brake pad. The wear monitoring apparatus includes a sensor for monitoring the mutual relative excursion of two elements which excursion is attributable to frictional wear of the brake pad. The sensor is mounted on the sliding thrust piece and/or the transmission mechanism and determines relative excursion between the sliding thrust piece and the transmission mechanism.

  • Patent number: 5697474
    Abstract: A disc brake is described which is actuatable by a fluid pressure actuation apparatus. A brake application shaft (8) with a brake lever (6) extending approximately perpendicularly from the shaft is disposed inside a brake caliper housing (1). The ring-shaped space between the brake lever (6) and the region of the brake caliper housing (1) which surrounds lever (6) is sealed-off by a seal (18).

  • Patent number: 5433298
    Abstract: An actuating mechanism for a sliding caliper disc brake has an actuator shaft with a projection in the form of an involute with an increasing radius. The involute is linked to an arcuate shaped rolling element through a pin fitting in recesses in the respective parts. The rolling element applies pressure to a thrust piece for actuating the brake when the actuator shaft is rotated by a brake lever. The axis of the actuator shaft is displaced from the center plane of the thrust piece so that the line of contact of the projection and the rolling element is constantly on the center plane.
