ABSTRACT:
The invention relates to improved mechanism systems for controlling and assisting the operating effort of a mechanical member and is especially applicable to automatic assisted steering systems for automobile vehicles. The said servo-mechanism comprises essentially a steering shaft including two coaxial sections, the first section being coupled to a steering wheel for its rotation about the common axis of the two sections, while the second section is coupled to the mechanical member to be servo-controlled, this second section being fixed on an end sleeve which is coaxial and surrounds one part of the first, which is provided with a pin mounted in one of its diametral planes, the wings of said pin being identical and projecting over the same length from each side of the common axis, the second section co-operating with the first by means of the wings of said pin and an elastic member interposed between the pin and the second section. An electric servo-motor has its stator fixed with respect to the support of the mechanism and its rotor co-operates with the rotational drive about its axis of the section of the steering shaft on which the sleeve is fixed, either directly or by means of a member transmitting rotation to said section. A device for converting to electric signals, following a pre-determined law, the value of the angle of relative rotation of the section of the steering-shaft carrying the pin with respect to the section carrying the sleeve, cooperates with the section provided with the pin, and is connected by input terminals to a source of electrical energy and has output terminals connected to the supply terminals of the electric servo-motor. The relative rotation of the two sections of the steering-shaft is measured by an angular displacement detector.
