The invention relates to the field of railway vehicle vibration reduction parts, in particular to a hourglass spring for secondary vibration reduction, which comprises a rubber body, a support plate and a mounting plate, and the rubber body is provided with empty vibration reduction areas extending to the mounting plate on two sides of the support plate; the rubber body comprises side bearing areas located on the two sides of the empty vibration reduction area and a middle bearing area located on the inner side of the empty vibration reduction area. The outer ends of the side bearing areas are connected with the mounting plate, and the middle bearing areas are located on the inner sides of the side bearing areas and connected with the supporting plate. A backstop piece fixed on the mounting plate is arranged in the empty vibration reduction area, the backstop piece comprises a connecting plate and a rubber backstop block, a buffer gap I and a buffer gap II are respectively arranged between the rubber backstop block and the side bearing area as well as between the rubber backstop block and the middle bearing area, and when a load is borne, the rubber backstop block gradually gets close to the rubber body and is in contact with the rubber body to form a backstop. When the hourglass spring fails, the rubber stop block is used for stopping and continuously supporting a vehicle body to continuously run.
本发明涉及轨道车辆减振件领域,具体提供了一种二系减振用沙漏簧,包括橡胶体、支撑板和安装板,橡胶体中位于支撑板的两侧设有延伸至安装板处的空向减振区;橡胶体包括位于空向减振区两侧的侧部承载区和位于空向减振区内侧的中部承载区;侧部承载区的外端部与安装板连接,中部承载区位于侧部承载区内侧且与支撑板连接;空向减振区内设有固定于安装板上的止挡件,止挡件包括连接板和橡胶止挡块,橡胶止挡块与侧部承载区和中部承载区之间分别设有缓冲间隙一和缓冲间隙二,当承受载荷时,橡胶止挡块逐渐向橡胶体靠近并与橡胶体接触形成止挡。本发明可在沙漏簧出现失效现象时,通过橡胶止挡块进行止挡并继续支撑车体继续运行。
