<p>A coupling arrangement between a towing vehicle (1) and a trailer vehicle (17) includes a towing device (2, 10) which is connected to the towing vehicle. The towing device is provided with a towing member (10) arranged to engage a curved abutment surface (20) on the trailer vehicle. The abutment surface comprises two circular-arcuate edge sections (20a, 20b) located on engagement means (21). The towing member comprises two rolling, or non-rolling towing elements, for example in the form of runners (11, 12) which are arranged to be urged against the curved abutment surface (20) under the action of the force-generating means (5, 6 and 140 respectively). When the towing vehicle turns from a straight forward movement direction, the towing elements (11, 12) move along each of the circular-arcuate edge sections (20a, 20b) from a first position (Fig. 3), in which the two towing elements are located on a respective one of the circular-arcuate edge sections, to a second position (Fig. 4), in which both of the towing elements are located on the same edge section. The towing elements (11, 12) are either supported by an individual respective holder (110a, 110b), or by a common holder (10).</p> |
