The invention relates to an outer windshield for a railway vehicle. The outer windshield comprises a first frame installed on a carriage of the railway vehicle, a second frame used for connecting adjacent carriages, and a plurality of telescopic assemblies sequentially connected between the first frame and the second frame in the width direction. The telescopic assembly comprises a first windshield piece and a second windshield piece. An included angle alpha is formed between the first windshield piece and the second windshield piece, and the included angle alpha is configured to be capable of changing the angle, so that the telescopic assembly can stretch out and draw back in the width direction, and the outer windshield can deform in the width direction. In this way, the situation that the first windshield parts and the second windshield parts of the telescopic assemblies deform in a deformation mode to achieve deformation of the outer windshield is avoided, the service life of the outer windshield is prolonged, and the requirements for deformation performance and fatigue strength of the first windshield parts and the second windshield parts are lowered. Meanwhile, the first windshield piece and the second windshield piece do not need to be manufactured through molds, and therefore the manufacturing cost of the outer windshield is reduced.

    本发明涉及一种用于轨道车辆的外风挡,包括安装在轨道车辆的车厢上的第一边框、用于连接相邻车厢的第二边框,以及在第一边框和第二边框之间沿宽度方向依次连接若干伸缩组件。伸缩组件包括第一风挡件,以及第二风挡件。其中,第一风挡件和第二风挡件之间形成夹角α,夹角α构造成能够改变角度大小,使得伸缩组件能够沿宽度方向伸缩,以便外风挡能够沿宽度方向变形。通过此种方式就避免了若干伸缩组件的第一风挡件和第二风挡件以变形的方式来实现外风挡的变形,提高了外风挡的使用寿命,降低了对第一风挡件和第二风挡件形变性能和疲劳强度的要求。同时,第一风挡件和第二风挡件也无需通过模具制造,从而降低了外风挡的制造成本。
