  • Publication number: 20200055539
    Abstract: A method for assembling a rack-and-pinion steering gear may involve introducing a steering pinion into a housing opening of a steering gear housing such that a region of a narrowed portion of a pinion shaft is situated at a level of a rack to be inserted, introducing the rack into the housing opening of the steering gear housing such that the rack is pushed past the narrowed portion of the pinion shaft into a setpoint position, and moving the pinion shaft farther into the steering gear housing to an end position such that a toothing region of the rack enters into engagement with a toothing of the steering pinion.

  • Patent number: 8235166
    Abstract: A rotational speed superimposition device for a vehicle steering system is proposed, having an output shaft (2) which is aligned towards the input shaft (1) in its axial direction (22), having a first carrier arrangement (6) which rotatably positions the output shaft (2) and the input shaft (1) at least partly supported, having an auxiliary drive (5, 10) with a rotor (5) which is connected in an operative, torque-proof manner to a first gear element (4) of a superimposition gear unit (7), and having a second carrier arrangement (11) which is arranged in a fixed manner on the chassis and which holds the auxiliary drive (5, 10) and supports the rotor (5) so that it can rotate, wherein the rotor (5) of the auxiliary drive (5, 10) coaxially surrounds the output shaft (2) and/or the input shaft (1), and wherein the superimposition gear unit (7) transmits the rotational speed of the rotor (5) to the rotational speed of the output shaft (2) at a rotational speed ratio that is less than 1.
