An improved trailer coupling is provided for coupling a trailer 3 and a towing vehicle 30. The coupling 110 is provided with a mountable bifurcated restriction means or bifurcated guide 112, 114, 116, 118, that is used to prevent over pivoting whilst allowing greater pivoting angles to be conveniently achieved. As is known from the art, the trailer 3 suitably comprises steerable wheels 4 so that differential pivoting of the towing vehicle and trailer can be achieved. This is in addition to the tow bar connection that can pivot but not slide. The coupling further comprises a first pivot 14 means to pivotably interconnect the towing vehicle 30 and trailer 3 and a second pivot 24 means to pivotably interconnect the wheel steering 20 means of the trailer and the bifurcated guide. The second pivot 24 means comprises a slidable pivot that is guidable by the bifurcated guide 110 as the towing vehicle turns with respect to the trailer 3. |
