Abstract
The utility model discloses a connector for the bolster and the central plate of a railway wagon bogie. Grooves are arranged in the centers of a bolster and a central plate, the lower joint surface of a lower central plate is correspondingly provided with a convex platform which is positioned in the groove of the bolster, and the lower central plate and the bolster are tightly connected with a bolt. Thus, the matching structure of the convex platform and the grooves bears the vertical and the transverse swinging forces in the steering process of a wagon; the bolt only prevents the rotation of the central plate and enhances the connection, which greatly improves the reliability of the connector for the bolster and the central plate of a railway wagon bogie, thus, the utility model solves the problem that a central plate connecting bolt is broken in the connection of a railway wagon bogie.
Description
Technical field
The utility model relates to a kind of railway truck novel steering frame bolster and cartridge connection structure.
Background technology
According to Mid-term and Long-term Plan of the Railway Network and " railway technology policy " demand for development, China railways will progressively realize separating lines for passenger and freight, to there be the part circuit to take the lead in realizing separating lines for passenger and freight by 2012, be development novel load-carrying, quick lorry, further improving railway transportation capacity provides rare opportunity to develop.Existing truck bolster and cartridge connection structure, the problem that the tie bolt of appearance fractures.According to the developing direction of China's heavy haul railway, under the tissue of the Ministry of Railways instructs, carried out the development of novel steering frame bolster and cartridge connection structure.
Summary of the invention
The purpose of this utility model is that a kind of truck bolster and cartridge connection structure will be provided, and solves railway goods train bogie and occurs the cartridge tie bolt problem that fractures in connecting.
For achieving the above object, a kind of steering frame swing bolster of lorry provided by the utility model and cartridge connection structure, connect by bolted between truck center plate and bolster, it is characterized in that: on bolster cartridge face, be provided with groove, truck center plate is provided with and the cooresponding boss of described groove, and described groove cooperates with boss.
As preferred version, it is circular that the cross section of described groove, boss is respectively.
More optimal, described groove, boss lay respectively at the center of described bolster cartridge face, truck center plate.
Adopt the utility model, the boss of truck center plate falls in the bolster groove, between truck center plate and bolster again bolt up connect.Therefore, the fit structure of boss and groove has been born the vertical, horizontal oscillatory forces in the lorry steering procedure, bolt only works to prevent the cartridge rotation and further reinforces the connection, strengthened steering frame swing bolster of lorry and cartridge connection structure bonded assembly reliability greatly, solved railway goods train bogie and occurred the cartridge tie bolt problem that fractures in connecting.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
Fig. 1 is according to truck bolster and the cartridge connection structure 3D modelling scheme drawing that the utility model proposes.
The specific embodiment
According to Fig. 1, a kind of steering frame swing bolster of lorry provided by the utility model and cartridge connection structure have circular groove 1 in bolster cartridge face center, and should there be round boss 2 the following face of joint center of truck center plate mutually.During assembling, truck center plate boss 2 falls into bolster groove 1.Still use 3 fastening connections of bolt between truck center plate and bolster, bear the vertical, horizontal power in the use.Bolt plays and prevents that cartridge from rotating and the effect of reinforcement bonded assembly, and this connection structure has solved in the railway goods train bogie utilization and the problem that cartridge tie bolt 3 fractures occurred, and satisfies in the normal use safe and reliable simultaneously.
It should be noted last that, the above specific embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
