Claim:
An electromechanical brake comprising: an electric motor having a motor shaft and a rotor attached to the motor shaft; a rotation/translation converting transmission connected to the electric motor in a manner so as to actuate the brake; a housing accommodating the electric motor therein, wherein the housing has an end face and the motor shaft of the electric motor is rotatably supported within the housing; a cover attached to the housing at the end face of the housing; a switchable freewheel having clamping elements connected to the motor shaft, wherein the clamping elements are distributed around the motor shaft and are accommodated in an annular intermediate space between the motor shaft and the cover in a manner such that in an engaged position the clamping elements lock with respect to the motor shaft to permit rotation of the motor shaft in a brake applying direction of the brake and prevent the motor shaft of the electric motor from rotating in a releasing direction of the brake, and wherein the cover forms a bearing plate for the motor shaft of the electric motor and wherein the clamping elements of the freewheel are accommodated in the cover.
