The invention discloses a semitrailer, which belongs to the technical field of semitrailers and comprises a semitrailer head, a cab is arranged in the semitrailer head, a windshield is arranged outside the semitrailer head, at least two groups of wheels are symmetrically arranged on two sides of the semitrailer head, a traction seat is arranged at the tail of the semitrailer head, a semitrailer frame comprises a frame, and the semitrailer head is movably connected with the semitrailer frame through the traction seat. A front suspension plate is welded to the front end of the frame, and at least two sets of hydraulic cylinders are installed on the two sides of the top of the front suspension plate. The frame is originally lower than the semitrailer head. Through an arranged inclined plate, the front end of the frame is higher than the semitrailer head, so that when tubular goods are loaded, the tubular goods are wholly located on the semitrailer head; when the semitrailer is subjected to emergency braking, even if the tubular goods move forwards under the influence of inertia, the tubular goods are guided by the inclined plate to slide forwards higher than the semitrailer head, meanwhile, ribs arranged on the inclined plate can abut against the front end of the tubular goods to decelerate, and the tubular goods can be prevented from penetrating through the semitrailer head under the influence of inertia.
本发明公开了一种半挂车,属于半挂车技术领域,一种半挂车,包括车头,车头内设驾驶室,车头外设挡风玻璃以及两侧至少对称设有两组车轮,车头的尾部设有牵引座,一种半挂车的车架包括车架,所述车头通过牵引座和车架活动连接,且车架的前端焊接有前悬板,所述前悬板的顶部两侧安装有至少两组液压缸。原本低于车头高度的车架通过设置的斜板其前端高于车头,这样在装载管状货物时,其管状货物整体位于车头之上,在半挂车进行紧急制动时,即使管状货物受惯性影响向前运动也会通过斜板的引导高于车头向前滑动,同时在斜板上设置的棱条可以抵触管状货物的前端进行减速可以避免管状货物在惯性影响下贯穿车头。
