Abstract

An electromechanically actuated disc brake system for motor vehicles comprising a floating caliper and an actuating unit mounted with the caliper. The actuating unit is an electric motor which, by interpolation of a reducing gear, powers an actuating element, which in turn controls one of two sliding friction linings mounted inside the brake caliper, to interact with the disc brake. With the intent to reduce axial dimensions of the actuating unit, the present invention includes an electric motor with a rotor of ring-shaped design to radially surround the reducing gear.
