The invention discloses a high-speed rail vehicle bogie, which comprises wheel sets, axle boxes, a primary spring suspension device, a framework, a secondary spring suspension device and a foundation brake rigging; wheels of the wheel sets are all S1002CN tread wheels; the installation mode of the foundation brake rigging is a of three-point suspension structure, and a brake hanging bracket of the foundation brake rigging and a tread sweeping device installation seat are integrated into an integral structure on the framework; each axle box is of a split structure which can be separated top and bottom; the upper part of each axle box is provided with a fusing-type temperature sensor and a real-time temperature sensor, and the lower part of each axle box is provided with a wire off safety guard device; a traction rod of the secondary spring suspension device is a single traction rod; moreover, a center pin is additionally provided with an integral lifting device, and a set of two anti-hunting dampers of the integral lifting device is arranged at each side, and the anti-hunting dampers are asymmetrically designed in a manner that one damping coefficient is big and the other damping coefficient is small. The bogie has good dynamic performance, higher structural safety, reliability and economic efficiency, and can be adapted to the requirement of the rapid development of high-speed railways.
