Title (EN) RACK STEERING MECHANISM PARTICULARLY FOR MOTOR VEHICLES
(FR) MECANISME DE DIRECTION A CREMAILLERE, ESSENTIELLEMNT POUR VEHICULES A MOTEUR
Abstract:
(EN) A rack steering mechanism enables to reduce shocks due for example to the wheel fluttering, and which could be axially exerted on the rack (3). These shocks are transmitted to the drive pinion (2) and cause pertubating turning oscillations to the steering wheel. By means of a friction device mounted above the drive pinion (2), it is possible to adjust the "no-load rotation moment" of the steering in a reliable and wear resistant way. The friction device comprises a wear ring (11) secured to the steering shaft (4) on which a pressure is exerted by a friction disk (14) actuated by a spring (13) and secured to the casing (1) by means of a threaded ring (16) so as to avoid rotations.
(FR) Un mécanisme de direction à crémaillère permet de réduire les chocs dûs, par exemple, à un flageolement des roues, et qui pourraient s'exercer axialement sur la crémaillère (3). Ces chocs sont transmis au pignon (2) de la commande et provoquent des oscillations tournantes perturbatrices du volant. Grâce à un dispositif de friction installé au-dessus du pignon (2) de la commande, il est possible d'ajuster le "couple de rotation à vide" de la direction de façon fiable et résistante à l'usure. Le dispositif de friction comprend un anneau d'usure (11) fixé à l'arbre de direction (4), sur lequel une pression est exercée par un disque de friction (14) actionné par un resort (13) et fixé au boîtier (1) de façon à éviter des rotations par une bague filetée (16).
