Abstract
The utility model belongs to the technical field of railway wagons and specifically relates to a railway wagon center sill. The railway wagon center sill comprises a center sill body, a wearing plate and a center plate, wherein the center sill body comprises an upper cover plate, a lower cover plate and a web plate, the thickness of two ends of the lower cover plate of the center sill is larger than that of the middle of the lower cover plate of the center sill, and the thickness of two ends of the web plate of the center sill is larger than that of the middle of the web plate of the center sill; the wearing plate comprises a first embedded type wearing plate and a second embedded type wearing plate, the first embedded type wearing plate is connected to the center sill body through fastening pieces, and the second embedded type wearing plate is connected to the center sill body through fastening pieces; and the center plate is in clearance fit with a center plate hole on the center sill body. The railway wagon center sill has the advantages of being light in weight and capable of effectively improving stress conditions of the center sill and the whole wagon, improving the longitudinal force stressing conditions of the wagon and improving operation performances of the wagon.
Description
Technical field
The utility model belongs to the railway truck technical field, is specifically related to a kind of railway truck central sill.
Background technology
Traditional railway truck central sill adopts the monolithic devices steel structure, from great, and because the cross section at central sill right ends and middle part is identical; Depth of beam in when design and production, being difficult for regulating causes the force-bearing situation of central sill and car load undesirable, and then has influence on the drive ability of vehicle; And the wearing plate on the lorry central sill is to be welded on the central sill; The effort of taking a lot of work when need changing, the cartridge of lorry central sill then be through bolted connection in the cartridge hole of central sill, the risk that comes off is arranged.
Summary of the invention
The utility model technical matters to be solved provides a kind of railway truck central sill of light-duty variable section.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of railway truck central sill; Comprise central sill main body, wearing plate and cartridge; Said central sill main body comprises upper cover plate, lower cover and web; The thickness at the lower cover two ends of said central sill is greater than the thickness at said central sill lower cover middle part, and the thickness at the web two ends of said central sill is greater than the thickness at web middle part in said.
Said wearing plate comprises the first embedded wearing plate and the second embedded wearing plate, and the said first embedded wearing plate is connected on the said central sill main body through fastener, and the said second embedded wearing plate is connected on the said central sill main body through fastener.
Cartridge hole on said cartridge and the said central sill main body forms interference fit.
The said first embedded wearing plate is connected on the said central sill main body through countersunk-heat bolt, nuts and washers, and the said second embedded wearing plate is connected on the said central sill main body through countersunk-heat bolt, nuts and washers.
The beneficial effect of the utility model isFrom heavy and light, and embedded wearing plate and cartridge and the change of central sill main body connection mode, can effectively improve central sill and car load force-bearing situation, improve the stressing conditions of longitudinal direction of car power, improve the drive ability of vehicle.
