<p>A vehicle for terrestrial use is equipped with three distantly arranged supporting means (3, 4) for forward movement. Two of these supporting means (3) being displaceable in unison by means of a common steering device (12, 13, 14) and are each pivotally arranged on an extended supporting arm (5) at the front part of the vehicle. The third supporting means (4) being of a traditional nature of support only and each relevant extended pivot (9) of the said two supporting means (3) lying in a common plane which intersects the plane containing the said vehicle's two supporting contact surfaces and the points of support, each extended pivot axis (16) taking a rearward angle of inclination with respect to the vertical plane through the longitudinal axis of the vehicle. The points of intersection (19) of each pivot axis (16) with the horizontal plane of support lying in an outward direction perpendicular to the vehicle's longitudinal axis and sidewardly and outwardly away from each of said points of contact whereby the arrangement being suchlike that while the vehicle traversing a curved path, the vehicle's frame is subjected to a "pendulum" action inthe direction of turning. This "pendulum" actions causes a relative different movement while progressively turning the vehicle's supporting means located at the inner part of the curve moving more in a forward direction, whereas the supporting means located at the outer part of the curve being more retracted with respect to the said forward movement and vice versa.</p> |
