The invention relates to the technical field of vehicle driving mechanisms, in particular to a driving and braking integrated gearbox, a bogie, a driving system and a railway vehicle. The gearbox comprises a gearbox shell, a gear set, an inertia mechanism and a braking device, the input end of the gear set is connected with an input shaft, and the output end of the gear set is connected with a mandrel; according to the gearbox, the inertia mechanism and the braking device are added to the gearbox, the inertia mechanism is connected with the gear set and can rotate along with the gear set, the braking device is connected with the inertia mechanism and used for applying braking force to the inertia mechanism so as to brake the gear set and the mandrel, and therefore the braking function of the gearbox is achieved; driving and braking integration of the gear box is achieved, a brake does not need to be installed at other positions of a vehicle system, the cost of independently installing a braking system is reduced, meanwhile, a vehicle driving system is more integrated, the situation that the independent brake occupies the space of a bogie is avoided, and light-weight design of a vehicle is achieved easily.
本发明涉及车辆驱动机构技术领域,尤其涉及一种驱动制动一体化齿轮箱、转向架、驱动系统及轨道车辆,齿轮箱包括齿轮箱壳体、齿轮组,惰性机构和制动装置,齿轮组的输入端连接输入轴,齿轮组的输出端连接芯轴,该齿轮箱通过在齿轮箱添加惰性机构和制动装置,惰性机构连接齿轮组,能够随齿轮组转动,制动装置连接惰性机构,制动装置用于对惰性机构施加制动力以对齿轮组和芯轴实现制动,从而实现齿轮箱的制动功能,本发明实现了齿轮箱的驱动和制动一体化,无需在车辆系统的其他位置安装制动器,减少了单独安装制动系统的成本,同时使车辆驱动系统更加集成化,避免单独的制动器占用转向架空间,有利于实现车辆轻量化设计。
