<p>HIGHWAY TRAIN In a highway train a wheeled and steerable, motordriven vehicle is combined at least with a first load carrier having its forward end portion rested on a first "fifth wheel" supported by the rear portion of the tractive vehicle, an auxiliary wheeled vehicle having a front portion with a second "fifth wheel" supporting the rearward end portion of the first load carrier, a second load carrier having its forward end portion rested on a third "fifth wheel" supported by a rear portion of the auxiliary vehicle, and an additional wheeled vehicle supporting the rear end portion of the second load carrier, the first load carrier being en route supported solely by the first and second "fifth wheels" in a manner to be free to occupy a limited angular position in a generally horizontal plane relative to both the tractive vehicle and the auxiliary vehicle. The auxiliary vehicle has fixed front wheels and rear wheels which by means of a steering mechanism are turned in response to any horizontal angular displacement occurring between the first load carrier and the auxiliary vehicle when the train passes through a curve and this in such manner that the auxiliary vehicle will always seek itself back to a position in a straight line with the first load carrier.</p> |
