Abstract

The utility model discloses a carbon fiber material framework, and relates to the technical field of railway carriage bogie framework manufacturing. The carbon fiber material framework comprises two arch-shaped side beam assemblies, an X-shaped bearing cross beam and two side beam double-spring-set supporting seats. Each arch-shaped side beam assembly comprises an arch-arm-shaped upper beam and a bowstring-shaped lower beam, and each X-shaped bearing cross beam comprises two arch-shaped plate beams. The arch-arm-shaped upper beams, the bowstring-shaped lower beams and the arch-shaped plate beams are all made of beam-type carbon fiber materials, the material science characteristics of high hardness, high elastic deformation performance, low forming process cost, great reduction of unit mass and the like of the carbon fiber materials are fully utilized, and on the premise that the mechanical structural strength is met, light weight of the bogie structure is effectively achieved, and the framework also has advantages in the aspects of increasing the maximum speed per hour of the rail vehicle, reducing the rail load, reducing the abrasion of wheels, saving power energy and the like.

Description

technical field [0001] The invention relates to the technical field of railway passenger car bogie frame manufacturing, in particular to a carbon fiber material frame. Background technique [0002] Traditional railway passenger car bogies are mainly made of low-carbon steel, forged steel or cast steel steel plates and steel pipes, and are manufactured in the form of welding to form an overall structure. This method requires extremely high welding technology, and it is difficult to avoid weld quality problems. At the same time, all kinds of steel bogies are relatively heavy, and their mass accounts for more than 40% of the vehicle's mass. On the premise of ensuring the reliability of steel welding and structural strength in line with mechanical requirements, further improvements are made by reducing material thickness or reducing the number of components. There is very little room for weight reduction. However, the weight reduction method of further reducing the size of the ...
