Quick railway goods train bogie

Abstract

The present invention relates to railway goods transporter, and is especially one bogie for railway goods train. The bogie for railway goods train includes one wheel pair, one framework, one swing bolster, one suspension device and one foundation brake rigging. The foundation brake rigging includes brake disk mounted on the shaft of the wheel pair, braking cylinder and clamp, and has brake block and clamp assembly installed on the framework. The present invention features the two stage suspension including the first stage suspension of composite metal fluid rubber spring and locating axle box and in the position between the framework and the wheel pair axle box, and the second stage suspension of rubber-metal pad between the framework and the swing bolster. There are also one longitudinal drawing unit, one transverse damping device and one automatic empty weight vehicle regulator. The bogie has small axle weight, high speed, good braking performance, and can raise the vehicle stability and safety.

Description

(1) Technical field: [0001] The utility model relates to a bogie for a fast railway freight car, which relates to a railway cargo transportation device, in particular to a bogie for a railway freight car. (two) background technology: [0002] In order to adapt to the rapid development of my country's railways, new railway equipment is constantly emerging. In recent years, the speed of the main bogie of my country's railway freight cars has generally reached 120km / h, but to achieve a higher speed is affected by the structure of the bogie, such as the traditional three-piece bogie with large unsprung mass and wheel-rail force Increase, the wear of the wheel and rail is serious, and the wear of the suspension is also serious. The automatic conversion device for empty and heavy vehicles adopts the indirect weighing method, the braking performance of the vehicle cannot meet the requirements of fast running of the vehicle, and as the speed increases, the dynamic performance of the...

Problems solved by technology

In recent years, the speed of the main bogie of my country's railway freight cars has generally reached 120km / h, but to achieve a higher speed is affected by the structure of the bogie, such as the traditional three-piece bogie with large unsprung mass and wheel-rail force Increased, the wear of the wheel and rail is serious, and the wear of the suspension is also serious

The automatic conversion device for empty and heavy vehicles adopts the indirect weighing method, the braking performance of the vehicle cannot meet the requirements of fast running of the vehicle, and as the speed increases, the dynamic performance of the bogie will deteriorate, and the stability and Security could be improved
