ABSTRACT:
This clutch comprises centrifugal weights (11) which are arranged radially in a hub (12) fastened to the output shaft (2) of an electric motor (1), returned to the position of rest by means of springs (21), and which, when the centrifugal force is sufficient, can come into engagement with the axial ends (26a) of an elastic ring (26) capable of transmitting the torque of the shaft (2) frictionally to a part (28) carrying an input pinion toothing (4) of a gear train for controlling the part to be driven. This arrangement simplifies the structure of the clutch in comparison with that of known clutches.
