  • Patent number: 11161540
    Abstract: 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.
    Type: Grant

  • Publication number: 20210009188
    Abstract: A power steering system for a motor vehicle, including a steering column integrating an upper shaft and an intermediate shaft connected in rotation and relatively movable in translation, an upper tube and a lower tube connected in rotation and relatively movable in translation, the upper shaft being movable in rotation and connected in translation in the upper tube, and an assist module integrating an output shaft connected in rotation to the intermediate shaft via a torsion bar, a reducer including a worm screw driven by an assist motor and which meshes on a tangent wheel connected to the output shaft; and an angle measuring device including an inductive sensor, a lower target mounted secured to the output shaft and an upper target secured to an upper lateral face of a core made of a plastic material of the tangent wheel.

  • Patent number: 9981681
    Abstract: The present invention concerns a method for assembling a modular cradle (1) for a vehicle steering axle, said method comprising a prefabrication step (a), which involves separately producing a base (3), a first module (10) that comprises a first section (2A) of a steering housing (2) for guiding a rack, and a first bearing (11) for receiving a stabilizer bar (13), a second module (20), separate from the base (3) and from the first module (10), which comprises a second section (2B) of the steering housing (2) for guiding the rack and a second bearing (21) for receiving the stabilizer bar (13), followed by an assembly step (b), which involves mounting and securing the first module (10) on a left-hand receiving area (7) of the base (3), and the second module (20) on a right-hand receiving area (8) of said base (3).
