The invention relates to the field of railway vehicles, and provides a gearbox for a bogie, the bogie and a railway vehicle. The gearbox for the bogie comprises a box body which is suitable for being installed on one side of an axle, and a first reinforcing structure is arranged on the box body in the vertical direction of the box body; the shaft sleeve is suitable for sleeving an axle and is connected with at least one end of the box body; the box cover is suitable for being installed on the box body from the side, away from the box body, of the axle. According to the gearbox for the bogie, the first reinforcing structure is arranged on the box body in the vertical direction of the box body, the bearing capacity of the box body in the vertical direction is improved, and the bearing function and the rotating function of an axle are separated. The shaft sleeve is connected with at least one end of the box body, so that the box body can bear a certain bending moment while keeping the original transmission function, and the problem that the box body cannot bear the bending moment is solved. The box cover is arranged on the side, away from the box body, of the axle, and equivalently, the position of the box separation face of the box body is adjusted, so that the bearing capacity of the box body can be improved structurally.

    本发明涉及轨道车辆领域,提供一种转向架用齿轮箱、转向架及轨道车辆。转向架用齿轮箱包括箱体,适于安装于车轴的一侧,沿箱体的竖直方向,在箱体上设置有第一补强结构;轴套,适于套设于车轴并与箱体的至少一端连接;箱盖,适于由车轴背离箱体的一侧安装于箱体。该转向架用齿轮箱通过沿箱体的竖直方向,在箱体上设置第一补强结构,提升了箱体在竖直方向上的承载能力,实现了车轴的承载与转动功能的分离。通过轴套与箱体的至少一端连接,使得该箱体在保留原有传动功能的同时,还可承受一定的弯矩,克服了箱体无法承受弯矩的问题。通过在车轴背离箱体的一侧设置箱盖,相当于对箱体的分箱面的位置进行了调整,使箱体在结构上可实现承载能力的提升。
