Abstract
Provided is a car underframe draft sill mechanism, comprising a hitch seat, a web, a draw beam upper cover plate and a draw beam lower cover and is characterized in that the web and the draw beam lower cover plate are spliced and tailor-welded; the hitch seat and the web, the hitch seat lower cover plate, a hitch seat reinforcing plate and the draw beam upper cover plate are welded together to form an enclosed cavity structure; the draw beam upper cover plate and a rib plate form a plug welding structure. The car underframe draft sill mechanism employs a steel plate tailor-welding structure, breaks through restriction of folding member thickness, increases a longitudinal force loading sectional area and thereby raises car body bearing longitudinal compression loading capability; the draw beam lower cover plate and the web are spliced; the hitch seat and the web, the hitch seat lower cover plate, the hitch seat reinforcing plate and the draw beam upper cover plate are welded together to form an enclosed cavity structure; and accordingly force transmission is more continuous and car body whole intensity and rigidity are raised; a transition plate plug welding structure is employed to solve the problem that the welding slit between a draw beam cavity inner rib plate and an upper cover plate can not be reached.
Description
Technical field
The utility model relates to a kind of draw beam structure of passenger train underframe steel structure, especially relates to the draw beam structure of high-strength stainless steel under-carriage.
Background technology
At present, the draw beam structure of stainless steel car body underframe of coach steel structure is mainly bending part assembly welding structure, fish belly type web and draw beam lower cover, connecting cross beam welding, coupler seat is fixed on the web with pulling rivet, for this kind structure, the car body strength aspect only can satisfy the requirement that the car body end applies clamp load 150t.But for the exigent passenger vehicle of end clamp load (be 363t such as AAR S-034 standard-required end clamp load), this draw beam structure can't satisfy the car body strength requirement, need design the novel traction girder construction, to satisfy the requirement of strength of steel structure of car body for this reason.
The utility model content
Technical problem to be solved in the utility model is design novel traction girder construction, improves bulk strength and the rigidity of underframe, satisfies the high request that car body strength meets the end clamp load (be 363t such as AAR S-034 standard-required end clamp load).
For solving the problems of the technologies described above, the utility model provides a kind of under-carriage draw beam mechanism, comprise coupler seat, web, draw beam upper cover plate, draw beam lower cover, it is characterized in that: web and draw beam lower cover are pegged graft and are welded, coupler seat and web, coupler seat lower cover, coupler seat stiffening plate, draw beam upper cover plate weld together, form the cavity structure of sealing, draw beam upper cover plate and gusset are the plug welding structure.
The utility model adopts the steel plate butt welding structure, has broken through the restriction of bending part thickness, has increased longitudinal force and has passed the sectional area that carries, and has then improved the ability of car body carrying longitudinal compression load; Draw beam lower cover and web are pegged graft, and coupler seat and web, coupler seat lower cover, coupler seat stiffening plate, draw beam upper cover plate weld together, and form the cavity structure of sealing, and the transmission of exerting all one's strength is more continuous, has improved bulk strength and the rigidity of car body; For solving draw beam die cavity inner reinforced plate and the unreachable problem of upper cover plate weld seam, adopt excessive plate plug welding structure.
Description of drawings
Fig. 1 is axonometric drawing of the present utility model;
Fig. 2 is the cutaway view along A-A line among Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, web 2 is pegged graft with draw beam lower cover 4 and is welded, coupler seat 1 welds together with web, coupler seat lower cover 6, coupler seat stiffening plate 5, draw beam loam cake 3 plates, forms the cavity structure of sealing, and draw beam upper cover plate and gusset 7 are the plug welding structure.
