Abstract

The invention relates to an electromechanical disk brake which has a switchable freewheel in order to be configured as a parking brake. The switchable freewheel includes a clamping roller freewheel having rollers for locking a motor shaft of an electric motor of the brake. A locating bearing of the motor shaft of an electric motor, and the freewheel are accommodated on a cover of a housing of the electric motor, and all the electric connections of the disc brake are routed via the cover. The number of components used can be reduced considerably by the integrated design. Moreover, the positional tolerances of the freewheel in relation to the motor shaft can be reduced with the aid of the invention.
