一种伸缩车架及半挂车
摘要：
本发明公开了一种伸缩车架及半挂车，该伸缩车架包括主车架、伸缩纵梁以及锁紧横梁；主车架和车体固定，主车架的中部设置有中纵梁，伸缩纵梁与中纵梁滑动连接；锁紧横梁套设在伸缩纵梁上，当锁紧横梁锁紧伸缩纵梁，并且锁紧横梁与车体固定时，伸缩纵梁和主车架相对固定，当锁紧横梁松开伸缩纵梁，并且锁紧横梁不与车体固定时，伸缩纵梁可相对于主车架在中纵梁的中空结构内伸缩，锁紧横梁可在伸缩纵梁上滑动。本发明的伸缩车架可以根据运输货物的长度，调整其自身长度，便于货物的运输。
摘要（英）：

The invention discloses a telescopic frame and a semitrailer; the telescopic frame includes a main frame, a telescopic longitudinal beam and a locking cross beam; the main frame is fixed to a vehicle body, a middle longitudinal beam is arranged in the middle of the main frame, and the telescopic longitudinal beam is slidably connected with the middle longitudinal beam; the locking cross beam sleeves the telescopic longitudinal beam; when the locking cross beam locks the telescopic longitudinal beam and the locking cross beam is fixed to the vehicle body, the telescopic longitudinal beam and the main frame are fixed relatively; when the locking cross beam unlocks the telescopic longitudinal beam and the locking cross beam is not fixed to the vehicle body, the telescopic longitudinal beam may telescope in the hollow structure of the middle longitudinal beam relative to the main frame, and the locking cross beam may slide on the telescopic longitudinal beam. The telescopic frame may adjust its length according to the length of cargoes under transporting to facilitate transporting of the cargoes.
