Benefits of technology
The present invention provides a railway wagon bogie with better strength and stiffness against anti-diamonding, which is convenient to assemble and maintain. Overall, the invention improves the performance of the railway wagon.
Problems solved by technology
Presently, due to the limitation of rails and bridges, the axle load has substantially been increased to the limit and is difficult to be increased any more.
However, the bogie has a low anti-diamonding stiffness and a low critical velocity.
Moreover, the space for mounting the supporting seat 5 is limited, resulting in the limitation to the length of the seat plate 52 and the height of the rib plate 53.
The connections between various members are achieved by welding, so that there are many weld joints being crowded and crossed, causing a large structural pre-stress.
Due to the welding operation, the quality of the weld joints cannot be ensured easily, and the tapered post 51 cannot be positioned precisely.
Thus, after the cross-braced rods 4 are mounted, the two side frames 2 are not in a desired rectangular shape, that is, the bogie is not positioned correctly, which is prone to cause non-uniform wear of wheels of the same bogie.
The design of bogies becomes more difficult for some wagons with a narrower outline gauge.
As a result, the difficulty in assembling is great.

A railway wagon bogie and a railway wagon are provided. The bogie includes wheel sets, side frames provided with triangular holes, a swing bolster provided with a preset hole in its body, and cross-braced rods. Cavities are formed in the side frames, symmetric around the center of the side frames, and located below the triangular holes. A connecting seat is provided in each of the cavities, and provided with a vertical mounting hole in a middle portion of the connecting seat. The cross-braced rods are elastically connected to the connecting seats through the mounting holes. In the railway wagon bogie and the railway wagon, the strength of the bogie is increased.
Description
PRIORITY CLAIM[0001]This application is the national phase of International Application No. PCT / CN2012 / 080676 filed on Aug. 29, 2012, and claims the benefit of priority to the Chinese Patent Application No. 201110296326.X, titled “railway vehicle bogie and railway vehicle” and filed with the state Intellectual Property Office on Sep. 27, 2011, which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to the railway wagon structure technology, and particularly to a railway wagon bogie and a railway wagon.BACKGROUND OF THE INVENTION[0003]A railway wagon used as a wheel-track transportation means generally includes a car body, a bogie and brake equipment. The bogie serves to support the car body, to guide the wagon to travel along rails, and to bear various loads from the car body and rails. The most common bogie for the railway wagon includes one swing bolster, two side frames, two wheel sets, a spring vibration damper and brak...
