Title (EN) VEHICLE WITH VARIABLE PLAY OF THE STEERING WHEEL
(FR) VEHICUE AVEC CHASSE VARIABLE DE LA ROUE DIRECTRICE
Abstract: front page image
(EN)The steering wheel of the vehicle is comprised of an annular roller bearing (22) of which the interior element (23) is made integral with one of its elements, for example the exterior element (25) of a second roller bearing (24) and of which the other annular element (21) carries a rim (19) and a tyre (20). The interior element (26) of the second roller bearing (24) is mounted by means of a pivot (40) to an articulated arm (17). The inclination of the second roller bearing and consequently the play of the steering wheel is variable owing to a double-acting hydraulic jack (42) supplied by a hydraulic pump (46) driven by a motor (47) controlled by an electronic circuit (48) coupled to a gear selector.
(FR)La roue directrice du véhicule comporte un roulement annulaire (22) dont l'élément intérieur (23) est rendu solidaire d'un des éléments, par exemple l'élément extérieur (25) d'un second roulement (24) et dont l'autre élément annulaire (21) porte une jante (19) et un pneumatique (20). L'élément intérieur (26) du second roulement (24) est monté au moyen d'un pivot (40) sur un bras articulé (17). L'inclinaison du second roulement et par conséquent la chasse de la roue directrice est variable grâce à un vérin hydraulique (42) à double effet alimenté par une pompe hydraulique (46) entraînée par un moteur (47) commandé par un circuit électronique (48) couplé à un sélecteur (49) des rapports de vitesses.
