Embodiment Construction

[0018] Such as figure 1 As shown, the sunken platform bolster structure of the rail vehicle in this embodiment consists of: an upper cover plate 2, a lower cover plate 1, and a web 5, and the lower cover plate 2 is provided with a gap 3 corresponding to the secondary steel spring of the bogie, and the position of the gap is An open box body 4 for inserting the upper end of the second series steel spring of the bogie is fixed. The box body 4 is located between the lower cover plate 1 and the upper cover plate 2. The box body 4 cooperates with the gap 3 to form a sinking platform structure. The box body 4 The top is provided with a pin hole 41 for the insertion of the secondary steel spring positioning pin, the back of the box body 4 is fixed with a positioning pin mounting seat 6 for the secondary steel spring positioning pin to be inserted, and the two sides of the corbel are fixed with the traction beam rod seat 7 . In this embodiment, in order to improve the strength of the...

Abstract

The invention relates to a bearing platform type sleeper beam structure for a railway vehicle. The bearing platform type sleeper beam structure comprises an upper cover plate, a lower cover plate and a web. A notch corresponding to a secondary steel spring of a bogie is formed in the lower cover plate. A box which is located between the lower cover plate and upper cover plate and used for being inserted into the upper end of the secondary steel spring is fixed at the notch. The box and the notch coordinate to form a bearing platform structure. A pin hole allowing for insertion of a secondary steel spring positioning pin is formed at the top of the box. A positioning pin mounting seat allowing for insertion of the secondary steel spring positioning pin is fixed at the back of the box. The bearing platform type sleeper beam structure is suitable for the bogie with secondary steel spring, the steel spring is disposed on a swing bolster, vehicle curve negotiation rate is increased, and vehicle production and maintenance cost is lowered. A connector of a sleeper beam and the steel spring of the bogie is submerged into the sleeper beam, and the rigidity and height requirements of the secondary steel spring can be satisfied by strength of the rib plate reinforced bearing platform box and the positioning pin mounting seat.

Description

technical field [0001] The invention relates to a rail vehicle sunken bolster structure, and belongs to the technical field of rail vehicle underframes. Background technique [0002] The corbel is one of the most important bearing parts of the railway passenger car body, which transfers all the weight of the car body to the bogie. And it forms a pair of "traction combination" with the bogie to drive the car body or the bogie to run on the track. [0003] With the increasing export of domestic railway passenger cars, how to meet the complex route requirements abroad has become an urgent problem to be solved in the design and manufacture of railway passenger cars. [0004] Due to the relatively good domestic line conditions, the common domestic railway passenger car structure cannot meet the relatively small curve radius requirements of some foreign lines. In addition, in some foreign countries, the railway operation capacity is relatively weak, and the line safety is not goo...
