The invention discloses a switching device and an integrated axle gear box, the integrated axle gear box comprises an axle, a gear box assembly, the switching device and a driving motor, the driving motor is installed on the axle gear box through the switching device, and separation and reunion of the driving motor and the axle gear box and transmission of retarding braking force are achieved through a clutch in the switching device. When the railway vehicle is in a long ramp downhill braking working condition, the driving motor provides a large part of braking force, and the problems that brake shoes are seriously abraded due to long-time braking, and braking failure, wheel tread scratching and the like are caused by too high temperature are solved. The use safety of the equipment is improved, and the application cost is reduced; the slope kinetic energy utilization rate of the rolling stock on the long ramp is improved, the rolling stock can run at a constant speed in cooperation with a proper traction control strategy, and the driving intensity of a rolling stock driver is greatly reduced; and due to the adoption of modular design and assembly, convenience is provided for upgrading and reconstruction of the existing vehicle.

    一种转接装置及集成式车轴齿轮箱,该集成式车轴齿轮箱包括车轴、齿轮箱总成、转接装置、驱动马达四个部分,驱动马达通过转接装置安装在车轴齿轮箱上,通过转接装置中的离合器实现与车轴齿轮箱的离合与传递缓速制动力。轨道车辆处于长大坡道下坡制动工况时,驱动马达提供一大部分制动力,减少闸瓦因长时间制动导致的闸瓦磨损严重、温度过高引起的制动失灵和车轮踏面擦伤等问题。提高了设备使用安全性,降低了运用成本;提升了机车车辆长大坡道下坡动能利用率,配合合适的牵引力控制策略,可实现机车车辆恒速运行,大幅降低机车车辆司机驾驶强度;且因采用模块化设计组装,为既有车辆上升级改造提供了便利。
