The invention discloses a railway vehicle bogie adopting double axle box suspension and a permanent magnet direct drive motor, axle box primary suspension devices are arranged inside and outside each wheel of an integral wheel pair of the bogie, and by adopting the scheme, the stress state of an axle is better than that of an axle of a conventional inner axle box and outer axle box bogie; the overall wheel set can be lightened to the maximum extent, and a foundation is laid for a shaft suspension type motor. The driving device is directly driven by a permanent magnet synchronous motor and is mounted on the left and right inner axle box bodies, a motor shaft suspension and direct drive mode is adopted, a gearbox structure can be avoided, the structure is simple, the axle distance of the bogie can be obviously reduced, and the self weight of the bogie can be reduced. The framework adopts an H-shaped framework and comprises two groups of longitudinally arranged side beams and a group of transversely arranged circular tube cross beams, and in order to adapt to a double-axle box suspension device, the end parts of the side beams of the framework are forked into two small longitudinal side beams. Through the design, the unsprung mass and the dead weight of the bogie can be obviously reduced, and the purpose of light weight is achieved.
本发明公开了一种采用双轴箱悬挂和永磁直驱电机的轨道车辆转向架,所述转向架整体轮对每个车轮内、外布置轴箱一系悬挂装置,采用该方案,使车轴受力状态比常规内轴箱和外轴箱转向架车轴更为良好,可实现整体轮对最大程度轻量化,为电机采用轴悬式奠定基础。驱动装置采用永磁同步电机直驱,安装在左、右两内轴箱体上,采用电机轴悬和直驱方式,可避免采用齿轮变速箱结构,结构简单,可显著减小转向架轴距,有利于降低转向架自重。构架采用H形构架包括两组纵向布置的侧梁和一组横向布置圆管横梁,为适应双轴箱悬挂装置,所述构架侧梁端部分叉为两个小纵向侧梁。通过以上设计,能显著降低簧下质量和转向架自重,达到轻量化目的。
