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.

Centrifugal clutch for a motor vehicle doorlock actuator

The clutch comprises at least one weight (11), and preferably two weights, disposed in a bell element (3) radially of the output shaft (2) of the motor (1), subjected to the action of an elastic element (21) for biasing the weight to a de-clutched position at rest, and capable of being driven by centrifugal force developed by the rotation of the shaft (2) of the motor (1) to a clutching position in which the weight engages the bell element (3). The bell element (3) is provided internally with a stressed spring (24) which frictionally bears against the inner wall of the bell element and is provided with at least one clutch dog (24a), and preferably two clutch dogs, cooperative with the weight or weights (11). The spring (24) limits the torque and permits avoiding rebounds in the event of a sudden stoppage of the bell element (3) at the end of the travel of the actuator.

Centrifugal clutch for an actuator for rendering inoperative an

A clutch is adapted to be interposed between an electric motor (1) and a gear train (5) for driving a screw on which is mounted a sleeve controlling a locking element. The clutch comprises weights (11) disposed in a hollow member (3) in a position radially of an output shaft (2) of the motor (1), said weights being biased by return springs (21) toward a de-clutched position of rest and being capable of being driven by the rotation of the shaft (2) to a clutching position in which they are engaged with the member (3). The weights (11) are mounted in a support constituted by a hub (12) defining a cavity (15) for the weights and by a cover (16) which closes said cavity (15) and is fixed to the hub (12). The cover (16) is adapted to permit the radial displacement of the weights (11) toward the member (3) under the effect of centrifugal force. This structure facilitates the placing in position of the weights and their assembly by an automatic machine.
