  "textContent": "The invention relates to a system of connecting a centre axle trailer to a tow vehicle in a manner that causes the effective pivotal point to be forward of the actual main tow hitch point when small angles of turn are made, in order to increase stability of the assembly. A main link to a central tow hitch is caused to rotate as required using a second offset link between trailer and tow vehicle, thus producing the required lateral displacement of the trailer over this range of turn angles. Provision is also made to enable the complete assembly to tolerate large angles of vehicle turn by automatically changing the mode of operation for these larger angles, so that the two linkages between tow vehicle and trailer lock in position, and the trailer pivot point changes to a point in the centre of the trailer mechanism.",
