HIGH-SPEED RAIL VEHICLE BOGIE

摘要

A high-speed rail vehicle bogie, comprising wheel sets (3), axle boxes (2), a primary spring suspension device, a framework (1), a secondary spring suspension device and a foundation brake rigging (6). Wheels of the wheel sets are all LMA tread wheels. An installation mode of the foundation brake rigging is of a three-point suspension structure, and a brake hanging bracket of the foundation brake rigging and an installation base of a tread sweeping device (13) are integrated into an integral structure on the framework. The axle boxes are of a split structure which can be separated vertically; the upper part of the axle boxes is provided with a fusing-type temperature sensor and a real-time temperature sensor which monitor an inner temperature of the axle boxes together, and the lower part of the axle boxes is provided with a derail safety guard device. A traction rod of the secondary spring suspension device is a single traction rod, moreover, a center pin (12) is additionally provided with an integral lifting device, and a set of two anti-hunting dampers (8) is arranged at each side, and the anti-hunting dampers are same in design parameter. 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.
