The invention relates to a railway vehicle air spring, an auxiliary spring and a secondary suspension device. The railway vehicle air spring comprises an upper vulcanization plate, an air bag, a lower vulcanization part, an inflation connector, a one-way valve and a friction block. The friction block is fixed on the lower vulcanization part; the two ends of the upper vulcanizing plate are connected with the two upper ends of the air bag respectively, the two ends of the lower vulcanizing part are connected with the two lower ends of the air bag respectively, and the upper vulcanizing plate, the air bag and the lower vulcanizing part are vulcanized, crosslinked and sealed to form an integrated structure through vulcanization; sealing ribs formed through vulcanization are arranged at the two upper end parts of the air bag and are used for sealing connection between the air bag and an upper cover plate connected with a vehicle body; the inflation interface is arranged on the lower vulcanization part and is used for inflating the interior of the air bag; the one-way valve is arranged in the inflation connector and used for guaranteeing that air flows from the outside of the air bag to the inside of the air bag in a one-way mode and meanwhile preventing the air from reversely flowing back.

    本发明涉及一种轨道车辆空气弹簧、辅助簧和二系悬挂装置。所述轨道车辆空气弹簧包括:上硫化板、气囊、下硫化部件、充气接口、单向阀和摩擦块;所述摩擦块固定于下硫化部件上;所述上硫化板的两端分别与气囊的两个上端部相接,所述下硫化部件的两端分别与气囊的两个下端部相接,通过硫化使所述上硫化板、气囊和下硫化部件进行硫化交联密封形成一体结构;所述气囊的两个上端部上具有通过硫化形成的密封筋,用于所述气囊和与车体相连的上盖板的密封连接;所述充气接口设置在所述下硫化部件上,用于对所述气囊内部进行充气;所述单向阀设置在所述充气接口内,用于保证气体方向由气囊外部至气囊内部单向流动,同时防止气体反向回流。
