<p>A device which is applicable to vehicles comprising a tractor (5) with one or two driven axles which have a fifth wheel (3) for harnessing the semitrailer, with the aim of increasing the load on the driving wheels (11,22,23) in order to avoid slippages and which includes the incorporation of a single or double acting hydraulic or pneumatic cylinder (8,19,30), which is fixed on the one hand to the fifth wheel (3) and on the other hand to the chassis of the tractor (5), in such a way that when the cylinder (8,19,30) is activated from the cabin it can initiate a swinging of the fifth wheel (3) and determine with it a series of structural stresses which make the load vary on the driving wheels (11,22,23). <IMAGE></p> |
