Abstract
A tow bar for connecting a towed vehicle to a towing vehicle, the tow bar comprising a towing vehicle connection mechanism connected to the towing vehicle; a towed vehicle connection mechanism connected to the towed vehicle; and an interconnecting mechanism connecting the towing vehicle connection mechanism to the towed vehicle connection mechanism. The interconnecting mechanism defines an interconnection central point and an interconnection vertical axis spaced rearwardly from the interconnection central point. The interconnecting mechanism is structured to accommodate substantially all pitch and roll movements between the towing and towed vehicles at and about the interconnection central point, and to accommodate substantially all yaw movements between the towing and towed vehicles at and about the interconnection vertical axis. The interconnection mechanism includes a disk spring device for accommodating variations in manufacturing tolerances and wear during use.
