Abstract
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.
