Abstract
A disc brake, particularly for utility vehicles, comprising a brake caliper that overlaps a brake disc, a tensioning device for tensioning brake pads, and an adjusting system for compensating for wear to the brake pads and/or brake disc. The adjusting system has at least one electric motor that serves as a drive. The at least one electric motor is mounted on the brake caliper in a manner that permits it to be accessed from the exterior.
Claims9
A pneumatically operated disc brake, comprising:
- a caliper extending over a brake disc;
- a brake application device having a rotary lever, the brake application device displacing brake pads against the brake disc;
- an adjusting system that compensates for at least one of brake pad wear and brake disc wear, wherein the adjusting system includes at least one electric motor to drive the adjusting system;
- wherein the at least one electric motor is arranged on the caliper such that it is accessible from an exterior of the caliper, the at least one electric motor being drivingly connected with components of the adjusting system arranged within the caliper;
- wherein the driving connection includes a shaft that penetrates a wall of the caliper and extends through a bore in the rotary lever of the brake application device.
