The invention concerns a guiding system comprising a front steering unit formed of two pivoting guiding arms (2) and (3) in vertical and paired working stress, each equipped with an inclined roller (12, 13) engaged on at least one guide rail on the ground (16). At the rear a follower-limiter module (47) for limiting the lateral clearance of the axle (8) to a maximum value in the form of a follower of the guide rail is mounted pivoting on the axle (8) and laterally movable within limits. The front steering unit and the follower-limiter module (47) are laterally connected on each side of the axle each time through a device (43, 44) for temporary lateral immobilisation with control for changing its state. The invention is useful for road vehicle manufacturers in particular for urban public transport.
Le système de guidage selon l'invention comporte un ensemble directionnel avant formé de deux bras pivotants de guidage (2 et 3) en contrainte verticale et de jumelage, équipés chacun d'un galet incliné (12, 13) en prise sur au moins un rail de guidage au sol (16). A l'arrière un module suiveur-limiteur (47) destiné à limiter le débattement latéral de l'essieu (8) à une valeur maximale sous la forme d'un organe suiveur du rail de guidage est monté pivotant sur l'essieu (8) et déplaçable latéralement de façon limitée. L'ensemble directionnel avant et le module suiveur-limiteur (47) sont reliés latéralement de chaque côté à l'essieu à travers à chaque fois un dispositif (43, 44) d'immobilisation latérale temporaire à commande de changement d'état. Cette invention intéresse les constructeurs de véhicules routiers notamment de transport en commun urbain.
