Embodiment Construction

[0028] The invention is described in a non-limiting example according to four embodiments, which allow the use of simple linear actuators as described above, either upstream or downstream in combination with motion conversion devices to provide more deceleration respectively, or by A linear actuator according to the invention coupled to a rotary rod constitutes a rotary actuator.

[0029] According to figure 1 The electric actuator of the solution corresponding to the first embodiment shown comprises:

[0030] - multi-phase stator 1;

[0031] - a rotor 2 comprising multi-pole magnets;

[0032] - a shaft with two separate threaded parts 3, 4;

[0033] - a first side plate 5 fixed relative to the stator 1 and having a first nut 6 fixedly connected to said stator 1;

[0034] - a second side plate 7 fixed relative to the stator 1;

[0035] - A control member 8 comprising a second nut 9 adapted to move in translation without rotation in the second side plate 7 by means of a s...

Abstract

An electric actuator comprising a threaded rod actuated in rotation by motor means, said threaded rod having a drive zone (10) extending on both sides out of threaded zones (3, 4), one of said threaded zones being connected to A fixed nut cooperates, the other of said threaded zones cooperates with a nut coupled to a control member movable along an axis parallel to the axis of said threaded zone, said threaded rod moving according to a helical motion.

Description

technical field [0001] The invention relates to the field of electric linear actuators for moving a transmission member over a limited stroke with the accompanying angular displacement of the member by conversion of a linear motion into a rotary motion. [0002] These linear electric actuators are commonly used in the vehicular field to manipulate fluid valves for the engine, or to move components that improve driver comfort. (Adjustment of air intake flow, fluid flow in adjustable suspension, activity of headlights or head-up display system on the windshield, etc.). Background technique [0003] The general principle of such an actuator is known and described, for example, in International Patent Application WO2010 / 027701. This patent application describes an actuator with a screw consisting of two threaded portions with cross-threads that are counter-inserted by multiple rotary motors, thereby allowing for a larger speed than a system including only one motor. force to t...
