Detailed description of the invention
Below in conjunction with accompanying drawing, aluminum alloy bodywork traction buffer structure is further described.
Embodiment one: this aluminum alloy bodywork traction buffer structure, rerail stay bearing plate 12 is provided with above lower cover 10, when car body unhook resets, rerail stay bearing plate 12 pairs of car bodies play a supportive role, the horizontal surface edge of upper cover plate 1 is provided with the hitch mount pad one 2 vertical with upper cover plate 1 and hitch mount pad 23, hitch mount pad 1 and hitch mount pad 23 butt welding are composed of a fixed connection hitch mount pad 4, hitch mount pad 4 is designed to the combination of hitch mount pad 1 and hitch mount pad 23, object is uniformly distributed by clamp load, comparatively original evenly distribution clamp load.Hitch mount pad 4 is fixedly connected with upper cover plate 1, connection mode is welding, the plane of hitch mount pad 4 and the plane orthogonal of upper cover plate 1, hitch mount pad 4 is provided with square hole and bolt hole, for installing hitch, hitch mount pad 2 both sides are provided with two wing plates 5, be fixedly connected with between hitch mount pad 4 with two wing plates 5, connection mode is welding, the vertical direction of hitch mount pad 4 is fixedly connected with inner side riser 1, inner side riser 27, outer cant board 1, outer cant board 29, inner side riser 1, inner side riser 27, outer cant board 1, parallel to each other between outer cant board 29, add two pieces of risers, inner side riser 1 is only had in prior art, with inner side riser 27, the outer cant board 8 increased and outer cant board 9 can share the stress at hitch mount pad 4 place, add the intensity of car body traction buffer structure, inner side riser 1 is fixedly connected with upper cover plate 1, connection mode is welding, inner side riser 27 is fixedly connected with upper cover plate 1, connection mode is welding, outer cant board 1 is fixedly connected with upper cover plate 1, connection mode is welding, outer cant board 29 is fixedly connected with upper cover plate 1, connection mode is welding, alleviate relative to aluminum alloy bodywork traction buffer structure quality of the prior art, welding capacity reduces, deformation quantity reduces, also solve problem of stress concentration of the prior art simultaneously.Lower cover 1 spiral-lock is above inner side riser 1, inner side riser 27, outer cant board 1, outer cant board 29, hitch mount pad 4 and wing plate 5.As shown in Figure 5, in order to increase the holding capacity of aluminum alloy bodywork traction buffer structure further, wing plate 5 is provided with delthyrium, and the delthyrium effect of wing plate 5 is to weaken rigidity own, make compressive force be delivered on outer cant board 1 and outer cant board 29, solve inner side riser problem of stress concentration.
In order to strengthen the intensity of aluminum alloy bodywork traction buffer structure further, two hitch stiffening plates 11 are provided with between inner side riser 1, inner side riser 27, hitch stiffening plate 11 is welded on hitch mount pad 4, while the intensity increasing aluminum alloy bodywork traction buffer structure, by increasing a large amount of section bar, to increase the work capacity of aluminum alloy bodywork traction buffer structure intensity much little relative to of the prior art for the work capacity increasing hitch stiffening plate 11, and weight also alleviates a lot.
By hitch mount pad 1 and hitch mount pad 3 to after being welded into a complete hitch mount pad 4, upper cover plate 1 is placed, hitch mount pad 4 is welded on the edge of upper cover plate 1, the line of centers of guarantee hitch mount pad 4 and the line of centers of upper cover plate 1 are point-blank, when hitch is stressed, hitch mount pad 1 and hitch mount pad 23 can share the stress of hitch uniformly, solve the problem that stress is concentrated.Weld two wing plates 5 in the both sides of hitch mount pad 4, wing plate 5 is also welded on upper cover plate 1 simultaneously.Then welding inner side riser 1, inner side riser 27, inner side riser 1 and inner side riser 27 keeping parallelism, and symmetrical about the line of centers of upper cover plate 1.Following welding outer cant board 1, outer cant board 29, outer cant board 1 and outer cant board 29 keeping parallelism, and symmetrical about the line of centers of upper cover plate 1.Like this, outer cant board 1 and outer cant board 9 on average can share the stress of inside stand plate 1 and inner side riser 27.In order to strengthen the intensity of aluminum alloy bodywork traction buffer structure further, hitch stiffening plate 11 is welded between inner side riser 1, inner side riser 27, hitch stiffening plate 11 is welded on hitch mount pad 4, consider the deflection caused by welding and space problem, the preferred 2-6 of quantity of hitch stiffening plate 11 is individual.Wing plate 5 has delthyrium, makes compressive force be delivered on outer cant board 1 and outer cant board 29, solve inner side riser problem of stress concentration.Finally by lower cover 1 spiral-lock above inner side riser 1, inner side riser 27, outer cant board 1, outer cant board 29, hitch mount pad 4 and wing plate 5, lower cover is welded with inner side riser 1, inner side riser 27, outer cant board 1, outer cant board 29, hitch mount pad 4 and wing plate 5.
After all welding jobs complete, overall processing upper cover plate 1, to eliminate the distortion that welding brings.
