双“S”辐板车轮是设计时速为160 km的准高速车轮,其辐板形状极为特殊,为双“S”型,与驼峰十分相像。由于在改善列车运行时车轮受力情况等方面具有较高的科学性,因而
Double “S” spoke wheels are quasi-high-speed wheels with a design speed of 160 km / h. The webs are very special in shape and are double “S” shaped and resembles humps. Due to the high scientific nature of improving the train operation when the wheel force situation, and therefore
