The invention discloses a follow-up device capable of driving a semitrailer carriage to move longitudinally and a semitrailer applying the follow-up device. The follow-up device is located between a tractor and a semitrailer carriage and comprises a saddle, a slider-crank mechanism, a generating mechanism and a driving mechanism. When the semitrailer turns, as an included angle is formed between a tractor cab and the axis of the semitrailer carriage, the driving mechanism drives the crank sliding block mechanism to drive a multiplication planetary gear to longitudinally move backwards in a tooth groove formed by a fixed rack and a movable rack, the fixed rack drives the multiplication planetary gear to rotate, and therefore the multiplication planetary gear drives a saddle bottom plate to longitudinally move backwards; the follow-up backward movement adjustment of the semitrailer carriage is achieved, and the gap between the tractor cab and the semitrailer carriage of the semitrailer is enlarged; after turning is finished and the relative rotation returns to the straight running, the driving mechanism drives the generating mechanism to reset, the saddle longitudinally moves forwards, the gap between the tractor cab and the semitrailer carriage is reduced again, and the whole vehicle recovers to the wind resistance reducing state.
本发明公开了一种能够驱动半挂车车厢纵移的随动装置以及应用该随动装置的半挂车。该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,驱动机构驱动曲柄滑块机构带动倍增行星齿轮在固定齿条与活动齿条形成的齿槽内纵向后移,固定齿条驱动倍增行星齿轮旋转,从而使增行星齿轮驱动鞍座底板纵向后移,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;并且随着转弯结束后相对转动恢复到直行状态时,驱动机构驱动发生机构复位,鞍座纵向前移,再次缩小牵引车驾驶室与半挂车厢之间的间隙,整车又恢复到减小风阻的状态。
