原条运材公路曲线加宽与汽车尾杆的研究

原条运材汽车列车在曲线道路上运行，将引起较大的曲线加宽，一般辕杆式汽车列车的加宽值比分离式汽车列车小，而带有尾杆转向补偿器汽车列车的加宽值较小，其值为分离式汽车列车加宽值的一半，增设尾杆是减少曲线加宽值的有效措施。原条运材汽车尾杆长度可由原条汽车列车通过平、竖曲线工况和汽车车架尾部结构确定，尾杆可采用多节伸缩式结构。

A STUDY ON TRUCK TAIL SHAFT

The moving track is broadened when a truck-trailer goes round curverin a road.In general,the increment of the track of a shaft style truck-trtrailer is less than that of a seperating style one.The track increment of a truck-trailer equipped with tail shaft turning compensator is just half of thatof a seperation style truck-trailer.So,it is an effective method to set tailshaft to reduce the track increment.The length of a tail shaft for a trucktrailer can vary according to horizontal and vertical arc conditions and thetail structure of the truck-trailer,and the tail shaft is designed as a multijoint device which can be pulled forth and back.
