The invention relates to the technical field of railway vehicles, and provides a bullet train bogie and a railway vehicle, and the bullet train bogie comprises a framework and a wheel drive system. The framework comprises a bearing body and two plate springs, a center pin channel is formed in the middle of the bearing body, two installation channels are formed in the bearing body in the longitudinal direction of the framework, and the two plate springs are installed in the two installation channels respectively. The wheel driving system comprises a shaft core, a shaft sleeve and two wheels, the shaft core is rotationally installed in the shaft sleeve, a gear box is constructed on the shaft sleeve, a driving tooth is arranged in the gear box, the shaft core is sleeved with a driven tooth, the driving tooth is externally meshed with the driven tooth, and the two wheels are installed at the two ends of the shaft sleeve through bearings respectively and connected with the two ends of the shaft core through flexible plates respectively. Cushion blocks are arranged at the two ends of each plate spring respectively, and the cushion blocks are connected with the shaft sleeves. And the bearing main body and the plate spring replace the original cross beam and side beam structure, so that the lightweight effect of the framework is obvious.
