Abstract

Abstract Translated from French Dispositif de direction assistée hydraulique pour véhicule automobile du type à distributeur rotatif comprenant une chemise de distribution (3) prolongeant un organe de commande de direction (5), un rotor (7) de forme générale tubulaire disposé à l'intérieur de la chemise, une barre de torsion logée à l'intérieur du rotor et ayant une extrémité fixée au rotor et l'autre extrémité fixée à l'organe de commande de direction, et un circuit hydraulique pour générer une grandeur de commande en réponse à un déplacement angulaire imposé au rotor. Selon l'invention la barre de torsion comprend un partie active (10) de section constante en acier à haute élasticité et deux embouts (11), (13) en acier ordinaire engagés respectivement sur les extrémités de la partie active et fixés à celles-ci, les embouts étant respectivement rendus solidaires du rotor (7) et de l'organe de commande de direction (5). Hydraulic power steering device for a motor vehicle of the rotary distributor type comprising a distribution jacket (3) extending a direction control member (5), a generally tubular rotor (7) disposed inside the jacket, a torsion bar housed inside the rotor and having one end fixed to the rotor and the other end fixed to the steering control member, and a hydraulic circuit for generating a control quantity in response to an imposed angular displacement to the rotor. According to the invention, the torsion bar comprises an active part (10) of constant section made of high elasticity steel and two end pieces (11), (13) of ordinary steel engaged respectively on the ends of the active part and fixed to them. ci, the tips being respectively secured to the rotor (7) and the steering control member (5).
