Abstract
The invention relates to a steering device for a vehicle bogey fitted with wheels having pneumatic tires that run on a pair of runways forming a track along which the vehicle travels. The device comprises a steering caster whose mean plane is parallel or substantially parallel to that of the wheels of the bogey and which is capable of rotating about its own axis when engaging in a guide groove installed between the above-mentioned runways of the track ahead of each branch point. The caster is carried by the frame of the bogey via laminated link blocks that confer to the caster and relative to the bogey a small amplitude degree of freedom in rotation about a vertical axis passing through the center of the caster, and a similarly small amplitude degree of freedom in translation along the axis of the caster, but prevent the caster from moving relative to the bogey in the vertical direction.
