Problems solved by technology

[0002] At present, most high-speed freight car bogies on high-speed railways adopt the common load-bearing structure of the center plate and side bearings. Due to the constraints of cost, large difference between empty and heavy vehicles, and high speed grade requirements, it is neither possible to adopt the joint load structure mode of the center plate and side bearing of the traditional truck, nor the load mode of the secondary air spring of the high-speed passenger car bogie.

Abstract

The invention discloses a bogie framework for a high-speed rail wagon. The framework has a concave H-shaped structure and is provided with a large cross beam, two side beams, two small cross beams and mounting seats in various models. By the framework, the requirements of a double-stage rubber spring bearing and a single longitudinal traction pull rod can be met; and the design of the side beams can meet the requirement of positioning of a rocker arm type shaft box for a bogie of a high-speed wagon. By the bogie framework, the requirement that the shaft weight is 16.5t when the speed of the wagon is 200km / h and the requirement that the shaft weight is 18t when the speed of the wagon is 160km / h are met; and the bogie framework has the remarkable characteristics of simple structure, high popularity and reliable performance.

Description

technical field [0001] The invention relates to a railway freight car bogie frame, in particular to a high-speed railway freight car bogie frame. Background technique [0002] At present, most high-speed freight car bogies on high-speed railways adopt the common load-bearing structure of the center plate and side bearings. Due to the constraints of cost, large difference between empty and heavy vehicles, and high speed grade requirements, it is neither possible to adopt the joint load structure mode of the center plate and side bearing of the traditional truck, nor the load mode of the secondary air spring of the high-speed passenger car bogie. . In order to not only meet the basic requirements of railway freight cars, such as cost constraints, large differences between empty and heavy cars, and convenient maintenance, but also meet the requirements of the vehicle speed level of 200km / h, the first series of 200km / h freight bogies needs to adopt the rotary arm axle box For ...
