Abstract
An articulated vehicle has two body portions which are pivotally connected and supported on a frame. First and second wheelsets are pivotally mounted to and support the frame. The third and fourth wheelsets are provided for supporting the other ends of the first and second body portions, remote from the frame. A steering arrangement comprising a detecting device and a guiding device are provided, which can be in the form of a mechanical linkage. The first detecting device detects changes in the angle between the frame and the first body portion, while a second detecting device detects changes in the angle between the frame and the second body portion. Corresponding first and second guide devices respond to the detected angles; the first guide device guides the first and third wheelsets to radial alignment, while the second guide device guides the second and fourth wheelsets to a radial alignment.
