The invention relates to an automatic telescopic side protection device suitable for a freight train and the freight train, and belongs to the technical field of vehicles. The automatic telescopic side protection device suitable for the freight train comprises a side protection body which is arranged between a tractor and a trailer; the side defence body is configured such that the side defence body varies its length following an angle of the tractor relative to the trailer. According to the automatic telescopic side protection device suitable for the freight train and the freight train, the side protection body is arranged, the length of the side protection body is changed along with the angle of the tractor relative to the trailer, then the side protection length can be automatically adjusted when the tractor turns, interference with the trailer is avoided, and the side protection effect is improved. The structure of the vehicle body is effectively protected from being damaged, meanwhile, pedestrians or vehicles are prevented from entering the bottom of the vehicle from the gap of the connecting position of the tractor and the trailer, rolling accidents are avoided, and the vehicles and the pedestrians are protected and buffered.
本申请涉及一种货车列车适用的自动伸缩式侧防护装置及货车列车,属于车辆技术领域,该货车列车适用的自动伸缩式侧防护装置包括侧防主体,其设置于牵引车和挂车之间,所述侧防主体被配置为:侧防主体跟随牵引车相对于挂车的角度来改变其长度。本申请实施例提供了一种货车列车适用的自动伸缩式侧防护装置及货车列车,通过设置侧防主体,侧防主体跟随牵引车相对于挂车的角度来改变其长度,进而能在牵引车转弯时,自动调整侧防长度,不与挂车发生干涉,有效的保护车辆本体结构不受损害,同时避免行人或车从牵引车和挂车连接位置空隙处钻入车底,造成碾压事故,对车辆和行人起到保护、缓冲的作用。
