PCT No. PCT/EP84/00212 Sec. 371 Date Feb. 15, 1985 Sec. 102(e) Date Feb. 15, 1985 PCT Filed Jul. 11, 1984 PCT Pub. No. WO85/00562 PCT Pub. Date Feb. 14, 1985.In the disclosure document DE-OS No. 31 49 700 the theory is put forward that the effective point of attachment of a trailer opposite the towing vehicle can be transferred in the direction of the center of gravity of the towing vehicle. The invention concerns itself with the actual possibility of the transfer while taking structural conditions into consideration. In this respect, the invention shows that at least the joints located at the trailer are to be arranged at a lower level than the ball head of a normal trailer coupling. The distance in height should be considerable, for instance approximately 75 mm. The front joints are located at a cross member, said joints being pivoted around a longitudinal axis in a coupling housing which is fixed rigidly at the ball head of the trailer coupling and thus is immovable.
