The invention provides a rail transit vehicle integrated front end cover body and a manufacturing process thereof. The rail transit vehicle integrated front end cover body comprises a carbon fiber front end cover body shell and reinforcing ribs. The reinforcing ribs are fixedly installed on the inner wall face of the carbon fiber front end cover body shell, and the reinforcing ribs and the carbon fiber front end cover body shell are integrally formed. An upper groove is formed in the upper surface of the carbon fiber front end cover body shell, a plurality of upper protruding blocks are arranged in the upper groove, and the side wall face of each upper protruding block is an inclined face. A lower groove is formed in the lower surface of the carbon fiber front end cover body shell, a plurality of lower protruding blocks are arranged on the lower groove, and the side wall face of each lower protruding block is an inclined face. And a foam interlayer is filled in the carbon fiber front end cover body shell. Integrated forming of the front end cover body of the rail transit vehicle is achieved, procedures are reduced, the production efficiency is improved, the production cost is reduced, the product quality is guaranteed, the weight of the front end cover body of the rail transit vehicle is reduced, and the front end cover body is more convenient to produce and use.

    本发明提供一种轨道交通车辆一体化前端罩体及其制造工艺,包括有碳纤维前端罩体外壳和加强筋;加强筋固定安装在碳纤维前端罩体外壳的内壁面上,加强筋与碳纤维前端罩体外壳一体成型;碳纤维前端罩体外壳的上表面设置有上凹槽,上凹槽内设置有多个上凸块,上凸块的侧壁面为倾斜斜面;碳纤维前端罩体外壳的下表面上设置有下凹槽,下凹槽上设置有多个下凸块,下凸块的侧壁面为倾斜斜面;碳纤维前端罩体外壳内部填充有泡沫夹层。本发明实现了轨道交通车辆前端罩体的一体化成型,减少了工序,提高了生产效率,降低了生产成本,保证了产品的质量,减轻了轨道交通车辆的前端罩体的重量,使得前端罩体的成产和使用更加便捷。
