CABLE VERIN FOR INCREASED JOINT DEBATMENT

摘要

A cable actuator comprising a chassis (1), a screw (2) rotatably mounted on the chassis and driven by an electric motor, a nut (4) that engages with the screw and is combined with anti-rotation means such that rotation of the screw under the action of the motor causes an axial displacement of the nut, two cables (10) coupled to the nut on either side of same, the two cables being wound onto respective joint pulleys (11) each rigidly connected to a same joint shaft (12) and in which the joint pulleys have a helical groove, the helical grooves of the pulleys extending in opposing directions.
