The invention relates to a low-floor railway vehicle bogie which comprises a framework, axles, a primary suspension, a secondary suspension, wheels and motor gear cases. The framework comprises side beams, cross beams and girders. Each cantilever beam protrudes outwards from the center of the corresponding side beam. The motor gear cases are hung on the outer sides of the side beams. The two sides of each cantilever beam are provided with upper hanging seats. The girder located on the same side of the corresponding cantilever beam is provided with a lower hanging seat. An upper part composed of the motor gear cases is provided with two upper installation seats relative to the two upper hanging seats. A side part composed of the motor gear cases is provided with a lower installation seat relative to the lower hanging seat. The upper installation seats and the upper hanging seats are fixedly connected through first connecting structures. The lower installation seat and the lower hanging seat are fixedly connected through a second connecting structure. A three-point hanging mode is adopted in the bogie, stress of the cantilever beams can be effectively reduced, the overall bearing state of the framework is improved, and the use space of a passenger chamber in a vehicle can be effectively increased.
