The invention relates to a bogie of a rail traffic tool, in particular to a bogie of a straddle monorail train with double parallel shafts and a lower wheel axle, and aims to solve the problem of connection between an axle and an output shaft of an original gear box in a limited axial space size of the monorail train. By using the double-end spline transmission shaft and designing the connection and fixing mode of the double-end spline transmission shaft, the hollow axle and the gearbox, the utilization of the axial space is reduced, and the connection problem of the axle and the output shaft of the gearbox is solved; meanwhile, the problems that the service life of a bearing is shortened and the running resistance is increased due to the axial degree deviation between the axle and the output shaft of the gear box are solved; and meanwhile, the problem that the mounting precision is not easy to guarantee due to overlarge different axes is solved through elastic deformation of the long shaft. Meanwhile, the problem of quick wheel replacement of the monorail train is solved, the wheel replacement maintenance time of the monorail train can be saved, and the working efficiency is improved.
本发明涉及一种轨道交通工具的转向架,具体涉及一种并装双轴的下装轮轴式跨座单轨列车转向架,本发明的目的是解决单轨列车有限轴向空间尺寸内车轴与原有齿轮箱输出轴联接难题,通过使用双端花键传动轴并且设计双端花键传动轴与空心车轴以及齿轮箱的联接与固定方式来减小轴向空间的利用,解决车轴与齿轮箱输出轴的联接难题;也同时解决了因车轴与齿轮箱输出轴两者之间的轴度偏差导致的轴承寿命的缩短和运转阻力增大的难题;同时通过长轴的弹性形变补偿不同轴度过大导致的不容易保证安装精度的难题。与此同时,本发明还解决了单轨列车快速换轮的问题,可节省单轨列车换轮维修的时间,提高工作效率。
