RTHZ09A(Y25)


This kind of bogie is available to be used on the railway gauge of 1435mm. It is applied for new-making and servicing wagons. The axle load is 22.5T and the operating speed is 120km/h. The bogie consists of wheelset, axle box, suspension device, bogie frame, basic brake rigging, load-proportional device and etc.

The bogie frame is a welded fabrication with the character of high construction speed and low unspring weight. By adopting spherical surface pivot bearing, the contact area between the pivot bearing of bogie and car body is enlarged. The load is equably distributed, and the ability of delivering longitudinal and transversal force is strengthened. By adopting suspension system of two level stiffness springs, the vertical stationarity of tare wagon is improved, so both of the tare wagon and laden wagon are with excellent dynamic performance. By adopting Lenoir devices, the requirement of different damping force of tare and laden wagon is satisfied preferably. By adopting elastic side bearing, the hunting motion stability of bogie is improved. By adopting block brake, acts on both sides of each wheel, the brake efficiency is improved and the block wear is reduced. By adopting weighing device, the automatic adjustment of brake force of tare and laden wagon situation is achieved.
