Abstract: front page image
(EN)The invention relates to a steering system which is used to control the steering angle of steered wheels (13, 14) of a vehicle, comprising means (2) of determining the angular position of the steering wheel (1) and two hydraulic or electro-hydraulic systems (6, 5) which are each used to control an actuator (11, 12) that acts on the steering angle of the wheels (13, 14) according to the angular position of the steering wheel (1). The invention is characterised in that it also comprises means which are used in normal mode to operate the two hydraulic or electro-hydraulic systems (5, 6) simultaneously and means of temporarily de-activating one or other of said two hydraulic or electro-hydraulic systems as desired, particularly when the vehicle is moving.
(FR)Système de direction, assurant la commande de l'angle de braquage des roues directrices (13,14) d'un véhicule, comportant :• des moyens (2) de détermination de la position angulaire du volant (1) ;• deux circuits hydrauliques ou électro-hydrauliques (6,5) permettant de commander chacun un actionneur (11,12) agissant sur l'angle de braquage des roues (13,14), en fonction de la position angulaire du volant (1) ;caractérisé en ce qu'il comporte également :§ des moyens pour, en mode normal, faire fonctionner simultanément les deux circuits hydrauliques ou électro-hydrauliques (5,6) ;des moyens pour désactiver temporairement ô la demande et notamment en roulage l'un ou l'autre des deux circuits hydrauliques ou électro-hydrauliques.
