ABSTRACT:
The present invention relates to a retroaction-protected transmission module for a motor for driving a retroaction-endangered load, in particular of a gate, having a transmission (11) having a drive side and an output side and a blocking clutch (1) having a clutch state and a blocking state, the blocking clutch including a driveshaft (12), which has driver parts (2) on one end, between which clamping bodies (3) are movably located, which surround a head (4) of an output shaft (13), the head (4) of the output shaft (13) having coupling faces (5), which are in contact with the clamping bodies (3) in the clutch state and via which, in the clutch state, the clamping bodies (3) carried by the driver parts (2) in the event of a rotation of the driveshaft (12) transmit a torque from the driveshaft (12) to the output shaft (13), and a braking ring (6) having a clamping face (7) being located around the clamping body (3), against which the clamping bodies (3) are pressed by the coupling faces (5) in the blocking state when an external torque acts on the output shaft (12). According to the present invention, the blocking clutch (1) is located on the output side of the transmission (11) so that an external torque is absorbed by the blocking clutch (1) and the transmission (11) is thus protected from the effect of the external torque. The present invention also relates to a blocking clutch for a transmission module of this type.
