An in-vehicle switch mechanism for guiding a vehicle along a guideway at converging and diverging points of the guide rails in a guided vehicle system includes a support frame; a pivot assembly; a switch arm assembly pivotably mounted at its proximate end to the pivot assembly; a switch wheel rotatably mounted to the switch arm assembly at its distal end; an actuator for moving the switch arm between a deployed position in which the switch wheel engages a guide rail and a stowed position in which the switch wheel is free of the guide rail; and a biasing device interconnected between the support frame and pivot assembly for pre-loading the switch wheel against the guide rail when the switch wheel is deployed as the vehicle approaches the point of divergence; and an in-vehicle switch system which uses such in-vehicle switch mechanisms.

La présente invention concerne un mécanisme d'aiguillage embarqué permettant de guider un véhicule le long d'une surface de guidage à des points convergents et divergents des glissières dans un système de guidage pour véhicules comportant un bâti de support, un ensemble de pivotement, un ensemble de bras de contact fixé à pivotement par son extrémité proximale à l'ensemble de pivotement un actionneur permettant d'actionner le bras de contact entre une position déployée dans laquelle la roue d'aiguillage est en prise avec une glissière et une position repliée dans laquelle la roue d'aiguillage est dégagée de la glissière; et un dispositif compensateur interconnecté entre le bâti de support et l'ensemble de pivotement pour assurer la précontrainte de la roue d'aiguillage contre la glissière lorsque la roue d'aiguillage est déployée à l'approche d'un point de divergence. L'invention concerne également un système embarqué d'aiguillage mettant en oeuvre de tels mécanismes d'aiguillage embarqués.
