Abstract
A disk brake having a first friction brake lining, which for braking can be pressed against a brake disk by pivoting of a support lever. A brake caliper is embodied as a floating caliper and an adjusting device is provided with which a second friction brake lining is adjustable transversely to the brake disk. In this way, a support angle (α) and thus a magnitude of the self-boosting of the disk brake can be varied.
Claims8
A friction brake with mechanical self-boosting for a motor vehicle, comprising
- a brake body to be braked, said brake body having a braking surface,
- a first friction brake lining,
- a support element pivotably connected to and supporting the first brake lining,
- an abutment pivotably connected to and bracing the first friction brake lining upon braking at a support angle that is oblique to the brake body to be braked,
- an actuating device, with which the support element is pivotable and the first friction brake lining can as a result be pressed against the braking surface of the brake body, and
- an adjusting device (34), operable to adjust a spacing of the abutment (24) from the braking surface of the brake body (14).

- an actuating device, with which the support element is pivotable and the first friction brake lining can as a result be pressed against the braking surface of the brake body, and
- an adjusting device (34), operable to adjust a spacing of the abutment (24) from the braking surface of the brake body (14) so that the amount of force necessary from the actuating device to obtain the proper pressure of the first friction brake lining against the brake body can be adjusted.
