The invention relates to the technical field of train workshop accessories, and discloses a high-speed train full-wrapping type multifunctional outer windshield which comprises a full-wrapping air bag, the full-wrapping air bag is in a rectangular frame shape matched with the shape of a train compartment, an annular air bag space is formed in the full-wrapping air bag, and a plurality of isolation pieces are further arranged in the full-wrapping air bag. The air bag space is divided into a plurality of cavities by the plurality of isolation pieces, the plurality of cavities are sequentially arranged along the circumferential direction of the full-wrapping air bag, damping holes are formed in the isolation pieces, and the two ends of the damping holes are respectively communicated with the cavities on the two sides of the isolation pieces where the damping holes are located; the multifunctional outer windshield adopts a form of fully wrapping the air bag, has the functions of sound insulation, resistance reduction and rain and snow resistance, is provided with the damping holes, has rigidity and damping characteristics after the air bag is filled with compressed air, can buffer the impact between vehicles, reduces the application of shock absorbers in a workshop, and improves the service life of the vehicle. And intelligent control over linear high air pressure and curve low air pressure can be achieved through the control valves, and better dynamic performance of the train is obtained.
本发明涉及列车车间配件技术领域,公开了一种高速列车全包式多功能外风挡,其包括全包气囊,全包气囊呈与列车车厢形状相适配的矩形框形,全包气囊内形成有环状的气囊空间,在全包气囊内还设置有若干隔离片,若干所述隔离片将该气囊空间分隔出若干腔体,若干腔体沿全包气囊的周向依次排列,在隔离片上开设有阻尼孔,阻尼孔的两端分别与其所在的隔离片的两侧的腔体连通;该多功能外风挡采用全包气囊形式,具备隔音减阻,抵挡雨雪的功能,并设置有阻尼孔,气囊内充满压缩气体后,其具备刚度和阻尼特性,能够缓和车辆之间的冲击,减少车间减振器的应用,并且利用控制阀可以实现直线高气压和曲线低气压的智能控制,获得列车更优的动力学性能。
