Abstract

The present invention discloses an actuating unit for an electromechanically operable disc brake for automotive vehicles which is generally comprised of a drive unit or an electric motor, an actuating element, by means of which one of two friction linings that are slidably arranged in a brake caliper is moved into engagement with a brake disc, as well as a first and a second reduction gear. In order to uncouple the second reduction gear from the first reduction gear, it is disclosed in the present invention that the electric motor, the first reduction gear, and the second reduction gear are configured as at least two assemblies which can be handled independently.

Dependent claims

An actuating unit for an electromechanically operable disc brake for automotive vehicles which is arranged on a brake caliper in which two friction linings that cooperate with each one lateral surface of a brake disc are arranged so as to be slidable within limits, wherein one of the friction linings is movable into engagement with the brake disc by means of an actuating element by the actuating unit directly, and the other friction lining is movable into engagement with the brake disc by the effect of a reaction force generated by the brake caliper, comprising:

an electric motor,
a second reduction gear functionally connected to a rotor of said motor
a first reduction gear which is interposed between the actuating element and the second reduction gear, and wherein the electric motor rotor includes an annular design which radially embraces the first reduction gear, wherein the electric motor, the first reduction gear, and the second reduction gear are attached as at least two self contained assemblies which can be handled independently.
