Abstract of Disclosure: A chassis arrangement has a steerable element, in particular a wheel, steerable on tilting of said chassis relative to the ground. The steerable element is mounted on the chassis via first and second links. The first link is pivotally supported at one end on said chassis and supports a substantially horizontally disposed axle for said steerable element. The second link is pivotable about an axis disposed parallel or oblique to the ground and substantially intersecting the contact area where, in the straightahead position of the steerable element the latter contacts the ground. Means is provided between said first and second links defining a substantially vertical axis which substantially intersects the first said axis at said contact area. The steerable element is swivellable about said vertical axis to effect steering on tilting of said chassis due to pivotal movement of said second link about the first said axis under the moment created by the ground pressure and its moment arm about the first said axis resulting from tilting of the chassis. The chassis arrangement has the special feature that said means provided between said first and second links defining said substantially vertical axis is disposed in the centre region of said steerable element, in the region of said horizontally disposed axle.
