The invention discloses a follow-up device for driving a semitrailer carriage to turn and move backwards and a semitrailer, the follow-up device is located between a tractor and the semitrailer carriage, and the follow-up device comprises a saddle, a slider-crank mechanism, a generating mechanism and a driving mechanism. When the semitrailer turns, an included angle is formed between a tractor cab and the axis of the semitrailer carriage, the driving mechanism drives two transmission worms of the generating mechanism to rotate reversely, so that the slider-crank mechanism drives the saddle to longitudinally move backwards, and follow-up backward-moving adjustment of the semitrailer carriage is achieved. The gap between the tractor cab and the semitrailer carriage of the semitrailer is expanded; and along with resetting after turning is finished, the whole vehicle recovers to the state of reducing the wind resistance. According to the follow-up device, the gap between the tractor cab and the semitrailer carriage of the semitrailer can be reduced, the purpose of reducing wind resistance and oil consumption of the semitrailer is achieved, and the turning problem can be solved. The semitrailer with the follow-up device is small in wind resistance and low in energy consumption, and therefore the transportation cost is reduced.

    本发明公开了一种驱动半挂车车厢转弯后移的随动装置以及半挂车,随动装置,位于牵引车和半挂车厢之间,包括鞍座、曲柄滑块机构、发生机构以及驱动机构。在半挂车转弯时,随着牵引车驾驶室与半挂车厢轴线形成夹角,驱动机构驱动发生机构的两根传动蜗杆反向运转,从而使曲柄滑块机构带动鞍座纵向后移,实现半挂车箱的随动后移调节,扩大半挂汽车的牵引车驾驶室与半挂车厢之间的间隙;随着转弯结束后复位,整车又恢复到减小风阻的状态。本发明的随动装置能够实现在缩小半挂汽车的牵引车驾驶室与半挂车厢之间的间隙,以达到降低半挂车风阻和油耗的目的,并且能够克服转弯问题。具有该随动装置的半挂车的风阻较小,能耗较底,从而降低了运输成本。
