Electromechanically operated disk brake

摘要

The present invention discloses an electromechanically operable disc brake for automotive vehicles which is comprised of a floating caliper and an actuating unit arranged on the caliper. The actuating unit includes an electric motor which, by the intermediary of a threaded roller pinion with return of the threaded rollers, readjusts an actuating element in which one of two friction linings which are mounted displaceably in the brake caliper is moved into engagement with a brake disc.Especially with a view to minimizing the influence of disturbing forces and moments, the spindle of the threaded roller pinion is drivable by the electric motor and the actuating element is formed by the threaded nut of the threaded roller pinion according to the present invention.
