Abstract
A transmission brake is arranged in connection with an electric motor for an electric brake. The transmission brake shall allow rotation of the motor shaft in a brake applying direction, but when motor current is no longer supplied, the shaft shall be locked. Rotation of the shaft in the brake release direction pre-supposes reverse rotation of the motor. A clutch is arranged between the shaft and a non-rotational housing. For accomplishing an engagement of the clutch at a rotation of the shaft but not the motor in the brake release direction there is a ramp.
