Abstract

An actuating unit for use on an electromechanically actuated disc brake for automotive vehicles including a drive unit or an electric motor, an actuating element for actuating one of two friction linings displaceably arranged in a brake caliper, and a first and a second reducing gear. The first reducing gear is comprised as a ball screw, while a planetary gear is used as the second reducing gear. To increase the efficiency, the present invention discloses a coupling shaft used to transmit forces from the planet cage of the planetary gear to the threaded spindle of the ball screw. The ends of the coupling shaft form universal joints with the planet cage and the threaded spindle.
