A power steering system for a motor vehicle, having a steering column integrating an upper shaft and an intermediate shaft rotatably linked and movable in translation relative to one another, an upper tube and a lower tube rotatably linked and movable in translation relative to one another, the upper shaft being movable in rotation and linked in translation within the upper tube, and an assist module integrating an output shaft linked in rotation with the intermediate shaft via a torsion bar, a reducer having a worm screw driven by an assist motor and which meshes on a worm wheel linked to the output shaft; and an angle measuring device having an inductive sensor carried by an annular support having a central orifice dimensioned so as to let the upper tube pass, a lower target securely mounted around the output shaft and an upper target.

Power steering system with steering column retractable according to an improved backward stroke by means of a through inductive sensor

The invention relates to a gear reducer () for an assisted-steering module, including a casing (), a worm () which meshes with a worm wheel (), and a spring () for taking up gear play, which presses said worm () radially against the worm wheel (), the wall of the casing () being bored, away from of the axis (XX') of the worm, with an opening () sealed by a plug (), the spring () for taking up gear play including at least one retaining lug () which projects radially to the axis (XX&#x2032;) of the worm (), and the hub () of the plug () having a guiding wall () that is substantially transverse to the axis (XX&#x2032;) of the worm (), which is designed to be placed axially opposite said at least one retaining lug (), in order to prevent the axial movement of the spring () beyond a predetermined functional travel.
