Abstract: A towbar assembly wherein two individual towbars are arranged in a V-configuration between a towing vehicle and a towed vehicle. The leading ends of the towbars have special end connectors that hook around a single towing pintle so that each towbar carries approximately the same tensile loading irrespective of changes in vehicle pitch or roll attitude. Each towbar is essentially independent of the other towbar, whereby the towbar loadings are essentially in the direction of the bar longitudinal axis; bending forces are to a great extent eliminated. The invention is designed primarily for use in towing large heavy vehicles weighing in excess of fifty tons.
