火车没有方向盘,带你看看它如何调整方向

2017-05-08 08:07:39   

(央视财经《是真的吗》)俗话说“火车跑得快,全凭车头带”。虽然提起火车很多人都再熟悉不过,但火车驾驶室却像是一个神秘的地方,很少有人可以一睹真容。最近,网上就有不少网友在讨论关于火车驾驶室里到底有没有控制转向的方向盘。有网友说火车没有方向盘,但也有网友晒出了照片,以此证明火车上是有方向盘的。

那么,火车没有控制转向的方向盘,这个说法到底是真是假呢?为此央视财经频道《是真的吗》记者来到了北京铁路局北京机务段寻找答案。

记者最先走进了拥有尖端科技的动车组列车,子弹头造型的驾驶室内只有一个靠背椅,更多的是环绕着操作台的各种精密仪表和开关按键。但是记者环顾一周,并没有在操作台上看到方向盘或者类似圆形转盘的仪器。那会不会是因为动车组列车与普通列车在技术上有所差别的原因呢?

随后,记者来到了普通列车区域,但一连进入三列不同型号的火车驾驶室,却都没有看到类似方向盘的仪器。记者决定继续探寻,终于在一列火车的驾驶室里看到了操作台上的圆形转盘,尺寸比汽车的方向盘小了很多,单手就可以操控,记者试着用力,圆盘也像汽车的方向盘一样旋转了起来。难道这就是火车的方向盘吗?为了更加仔细的观察,记者决定跟随着这列火车行驶一段时间。一段时间后记者发现,只有在刚发车时,司机旋转了圆盘。但是在切换方向,包括转弯处都没有再使用它,这又是怎么回事呢?难道这个小转盘并不是用来控制方向的吗?

北京机务段京广机车队 党支部书记 李晓东:“这个说法是真的,火车上没有方向盘。你看到的那个圆形的手轮它不是方向盘,是机车调速用的调速器。”
