BOGIE FOR HIGH-SPEED RAILWAY VEHICLE

摘要

A bogie for a high-speed railway vehicle includes a wheel set, an axle box, a primary spring suspension device, a frame, a secondary spring suspension device and a foundation braking device. A wheel of the wheel set has an LMA wheel tread. The foundation braking device is mounted by a three-point hitch structure. The axle box is a structure which is separatable in a vertical direction, and an off-line safety protecting device is mounted at a lower portion of the axle box. A traction rod of the secondary spring suspension device is a single traction rod. A center pin is provided with an integral hoisting device. Two anti-yaw dampers, as a group, are arranged at either side of the secondary spring suspension device, and the two anti-yaw dampers have the same damping coefficient.
