Abstract

Ce dispositif est du type de ceux comprenant un mécanisme roue-vis sans fin auquel un couple d'entrée est amené depuis l'arbre de direction, et duquel l'effort d'entrée est transmis par l'intermédiaire d'un mécanisme pignon-crémaillère à la timonerie de direction un vérin hydraulique à double effet apte à agir sur la crémaillère, et un système de valves commandant l'écoulement du fluide sous pression vers le vérin. Dans le dispositif selon l'invention, la roue 26 associée à la vis sans fin 12 et un pignon d'entraînement 22 de la crémaillère ont un pivot commun, mais des rayons de cercle primitif différents, de sorte qu'en service et sous un effort d'entrée prédéterminé, un mouvement de translation est communiqué au pivot 34, mouvement qui est utilisé pour l'actionnement du système de valves.This device is of the type of those comprising a worm wheel mechanism to which an input torque is supplied from the steering shaft, and from which the input force is transmitted by means of a pinion mechanism. rack at the steering linkage a double-acting hydraulic cylinder capable of acting on the rack, and a valve system controlling the flow of pressurized fluid to the cylinder. In the device according to the invention, the wheel 26 associated with the worm 12 and a drive pinion 22 of the rack have a common pivot, but different pitch circle radii, so that in service and under a predetermined input force, a translational movement is imparted to the pivot 34, which movement is used for actuating the valve system.
