ABSTRACT:
A forced steering mechanism is connected to a truck to steer an axle and associated wheels. Coupling means are provided for loosely connecting the car body of a vehicle to the truck and the forced steering mechanism. The coupling means permits relative lateral movement between the car body and truck while maintaining the forced steering mechanism in a position so as to permit self steering, but no forced steering when the vehicle is moving over tangent or rectilinear tracks. At the same time the degree of such lateral movement and amount of self steering is limited. The coupling means causes the forced steering mechanism to become operative when the vehicle is moving over sharply curved tracks.
