Abstract

L'invention concerne un mécanisme de direction assistée, notamment pour véhicules automobiles. Ledit mécanisme comporte un arbre en deux parties 1, 2. Un tiroir rotatif 3 solidaire de la première partie 1 est relié, par une barre de torsion 6, à la vis sans fin, supportant une douille de commande 5, de la seconde partie 2. La barre 6 est entourée par un piston creux de réaction 20. Entre la partie 1 et l'une des extrémités du piston 20, des surfaces obliques 21, 22, séparées par une rangée 25 de billes, constituent ensemble un dispositif médian de centrage Un ressort de centrage 31, logé dans une chambre 30, s'appuie contre ledit piston 20. Application aux véhicules automobiles, notamment aux engins de terrassement.The invention relates to a power-assisted steering mechanism, in particular for motor vehicles. Said mechanism comprises a shaft in two parts 1, 2. A rotary slide 3 integral with the first part 1 is connected, by a torsion bar 6, to the worm, supporting a control sleeve 5, of the second part 2 The bar 6 is surrounded by a hollow reaction piston 20. Between part 1 and one of the ends of piston 20, oblique surfaces 21, 22, separated by a row 25 of balls, together constitute a central centering device. A centering spring 31, housed in a chamber 30, bears against said piston 20. Application to motor vehicles, in particular to earthmoving machinery.
