MISALIGNMENT-TOLERANT CABLE ACTUATOR

摘要

A cable actuator comprising a chassis (1), a screw (2) mounted rotatably on the chassis and driven by an electric motor, a nut (4) engaging with the screw and associated with anti-rotation means such that a rotation of the screw, under the action of the motor, results in an axial movement of the nut, and two substantially parallel cables (10) coupled to the nut on either side of same. The cables are linked to an anchoring member (20; 30; 40) that is interposed between the nut and the cables, the anchoring member being secured to the nut while also being movable relative to same.

1. A cable actuator comprising:
a chassis (1); a screw (2) which is fitted so as to rotate on the chassis and is driven by an electric motor; a nut (4) which cooperates with the screw and is associated with anti-rotation means, such that rotation of the screw under the action of the motor gives rise to an axial displacement of the nut; two substantially parallel cables (10) which are coupled to the nut on both sides of it;characterized in that
the cables are connected to an anchorage unit (20; 30; 40) which is interposed between the nut and the cables, the anchorage unit being integral with the nut whilst being mobile relative to the latter; and the cables (10) are each wound around a pulley (11), the two pulleys (11) being integral with a same shaft (12).
