Abstract

Le système (SD3) comprend un barreau de crémaillère (3) et un boîtier de crémaillère (30), le barreau de crémaillère étant monté mobile en translation dans le boîtier de crémaillère, et le boîtier de crémaillère comprenant un boîtier de pignon (32) assurant un engagement par pignon du barreau de crémaillère avec un arbre de direction. Conformément à l’invention, le boîtier de pignon comprend deux pignons (320G, 320D) montés de part et d’autre du barreau de crémaillère et ayant des axes de rotation parallèles, le barreau de crémaillère ayant deux dentures (31G, 31D) engagées respectivement avec les deux pignons, les axes de rotation parallèles étant perpendiculaires à un plan de fixation d’une interface de fixation mécanique du boîtier de crémaillère avec un organe de châssis de véhicule, et les deux pignons ayant chacun des moyens agencés de façon à autoriser un couplage mécanique avec l’arbre de direction. Figure 3The system (SD3) comprises a rack bar (3) and a rack housing (30), the rack bar being mounted so as to be able to move in translation in the rack housing, and the rack housing comprising a pinion housing (32) ensuring engagement by pinion of the rack bar with a steering shaft. According to the invention, the pinion housing comprises two pinions (320G, 320D) mounted on either side of the rack bar and having parallel axes of rotation, the rack bar having two teeth (31G, 31D) engaged respectively with the two pinions, the parallel axes of rotation being perpendicular to a fixing plane of a mechanical fixing interface of the rack housing with a vehicle chassis member, and the two pinions each having means arranged so as to allow a mechanical coupling with the steering shaft.
