In order to solve the problem of heavy weight and sealing failure of double-deck folded shed windshield for rail vehicles on the basis of sound insulation, the utility model provides a double-deck folded shed windshield structure, which belongs to the field of rail vehicles, including arch-shaped outer shed, M-shaped inner shed, butt-joint cloth and press strip; two adjacent arch-shaped outer shed cloths are connected by a butt cloth, and two adjacent M-shaped inner shed cloths are connected by a butt cloth. Cloth connection, the upper and lower two adjacent outer shed cloth and the adjacent two inner shed cloth are connected together, the end of the inner shed cloth is extended at one end of the connection between the butt cloth and the inner shed cloth, and the pressing strip is installed at the end of the butt cloth; the sewing position of the utility model between any adjacent rings is at most three-layer shed cloth sewing, which reduces the difficulty of sewing and improves the processing technology. Yes. In the position of holding the strip, it is a single-layer shed cloth, which is convenient to clamp, and the size of the strip can be reduced to the minimum under the condition of guaranteeing the strength, thus playing a role in weight reduction.
【技术实现步骤摘要】
一种双层折棚风挡结构
本技术涉及轨道车辆的风挡,特别涉及一种轨道车辆的折鹏风挡。
技术介绍
折棚风挡作为轨道车辆风挡的一种,区别于整体都是橡胶的风挡,是通过压条和棚布组合在一起的风挡。棚布属于化工产品,属于橡胶类,外表为布的形状,功能也起到布的防风防雨作用,可以通过裁剪及缝纫形成想要的形状。压条是长条形带槽的金属制件,通常由铝制成,可以压紧到棚布上,从而把软的棚布支撑成为固定形状的折棚结构。在列车运行要求较高的情况下,要求折棚风挡具有一定的隔音效果,单层棚布的隔音效果较差,需要做成双层棚布并在双层棚布之间形成一定空腔,以增加整个折棚风挡的隔音效果。现有的双层棚布的折棚风挡主要结构及缺点有:1、单独的带压条外棚布,和单独带压条的内棚布通过连接框连接成整体折棚风挡,压条数量多,棚布空腔较大,有利于隔音,但是重量较重;2、内外棚布为同一方向弯曲,棚布边缘装夹到同一压条内,压条较宽,形成的棚布空腔较小,重量轻,但是不利于隔音;3、内外棚布通过连接布连接到一起,向不同方向弯曲,棚布边缘装夹到同一压条内,压条较宽,形成的棚布空腔较大,有利于隔音,但是重量也比较重。
