The invention discloses an asymmetric sleeper beam, belongs to the technical field of railway transportation equipment, and relates to the technical field of railway container flatcar sleeper beams. The asymmetric sleeper beam is of a variable-cross-section box-shaped structure formed by installing and welding high-strength weather-proof steel plates and comprises an upper cover plate, a lower cover plate, a web plate, a sealing plate and a side bearing installation base. The upper cover plate is of a symmetrical structure, and the joint of the upper cover plate and the middle beam upper cover plate is of a large arc structure. The lower cover plate is of an asymmetric structure, and the connecting portion of the lower cover plate and a flatcar middle beam is wider towards an end beam. Two parallel webs and a sealing plate fixedly connected with the two webs are fixedly arranged between the upper cover plate and the lower cover plate; a side bearing mounting seat is fixedly arranged at the lower part of the lower cover plate. The asymmetric sleeper beam only has a bearing function and is simple in structure, the width of the asymmetric sleeper beam is reduced to be close to the outer side of a side bearing, the asymmetric sleeper beam is narrower than an existing flatcar sleeper beam in the width direction, lightweight design is achieved, and the flatcar adopting the asymmetric sleeper beam can bear large longitudinal force. The asymmetric sleeper beam is used on a railway flatcar chassis with a full-length middle beam and without a side beam structure.

    一种非对称枕梁,属于铁路运输装备技术领域,涉及铁路集装箱平车枕梁技术领域。该非对称枕梁采用高强度耐候钢板组焊成变截面的箱形结构,包括上盖板、下盖板、腹板、封板、旁承安装座;上盖板为对称结构,上盖板与中梁上盖板连接处为大圆弧结构;下盖板采用不对称结构,与平车中梁连接部位向端梁处较宽;上盖板、下盖板之间固定设置有两块平行设置的腹板及固定连接两块腹板的封板;下盖板下部固定设置有旁承安装座。该非对称枕梁仅起承载功能,结构简单,宽度缩减至靠近旁承外侧,在宽度方向较既有平车枕梁窄,实现了轻量化设计,且采用该非对称枕梁的平车可承受较大纵向力。该非对称枕梁用于有通长中梁、无侧梁结构的铁路平车底架上。
