The present invention concerns a modular disc brake, preferably for a heavy road vehicle. The modular disc brake comprises a frame, a house and a cover. A brake mechanism forming a single pre-mounted unit is received in the house. The modules are held together by means of pull rods and nuts. The house is received in a recess of the frame. The cover covers the end of the house. The frame is of a floating type having openings to receive sliding pins.

Modular disc brake

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.
