Patent

CA 2310256

The invention relates to a vehicle (1) provided with a frame having two frame sections (3, 4) which are able to tilt with respect to one another. An opposite lock power transmitter (50) is connected to a steerable front wheel (13). The opposite lock power transmitter (50) is controlled as a function of the tilting moment on the frame sections (3, 4). By this means application of opposite lock is achieved, as a result of which the tilting section of the vehicles "drops into the bend" more rapidly and as a result of which increased manoeuvrability is obtained. The opposite lock power transmitter (50) can be used on vehicles having an active tilting system with drive means, such as, for example, hydraulic tilting cylinders (9, 9'), which are controlled by a sensor depending on the radius of the bend (24). The tilting moment generated by the tilting cylinders (9, 9') can optionally serve as a control signal for the opposite lock power transmitter (50). As a result of the active application of opposite lock, the tilting cylinders (9, 9') can be of relatively small construction.

L'invention concerne un véhicule (1) comprenant un cadre présentant deux parties (3, 4) de cadre capables de basculer l'une par rapport à l'autre. Un transmetteur assisté (50) de contre-braquage est connecté à une roue avant directrice (13). Le transmetteur assisté (50) de contre-braquage est commandé en fonction du moment de dévers sur les parties (3, 4) de cadre. Ce dispositif permet d'appliquer un contre-braquage de manière que la partie de dévers des véhicules "descend dans la courbe" plus rapidement et de sorte que l'on obtient une manoeuvrabilité supérieure. Le transmetteur assisté (50) de contre-braquage peut être utilisé sur des véhicules dotés d'un système actif de dévers doté de moyens de commande, tels que, par exemple, des vérins hydrauliques de dévers (9, 9'), lesquels sont commandés par un capteur en fonction du rayon de la courbe (24). Le moment de dévers généré par les vérins de dévers (9, 9') peut avoir la fonction optionnelle de signal de commande du transmetteur assisté (50) de contre-braquage. Du fait de l'application active du contre-braquage, les vérins de dévers (9, 9') peuvent avoir une structure relativement compacte.
