Description
Technical field
The utility model relates to the technical field of tractor accessories, especially relates to a kind of tractor truck the first beam assembly.
Background technology
At present traditional tractor truck the first beam assembly is in the process using, the design comparison of itself is simple, maximum displacement is larger, minimum safety factor is lower accordingly, under normal circumstances, above parameter determined tractor truck the first beam assembly ability to bear with and the safety of structure, there are some defects in the design of structure at the first beam assembly that adds itself, cause assembling tractor truck with existing design plan in traditional use always, make tractor truck load-carrying capacity and tractive force limited, safety factor is just corresponding reduction also.
Summary of the invention
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide under a kind of maximum bearing load of front cross rail steel plate that makes the first beam assembly, the bearing load in two holes of left and right side steel plate be and the bearing load in the first beam hole all under maximum duty, the static maximum stress of generation meets the tractor truck first beam assembly of corresponding requirements much smaller than yield strength, maximum displacement and the minimum safety factor of the first beam assembly steel plate.
For realizing above-mentioned object, the utility model provides following technical scheme:
A kind of tractor truck the first beam assembly, comprise front cross rail steel plate, the downside of the rear wall of described front cross rail steel plate is welded with the first joist steel plate perpendicular to front cross rail steel plate, the left and right sides of the rear wall of front cross rail steel plate is welded with respectively perpendicular to the left side steel plate of front cross rail steel plate and right side steel plate, downside respectively with the first joist steel plate of the left side right side wall of steel plate and the left side wall of right side steel plate is by being welded and fixed, the upside of the left side wall of described left side steel plate is welded with left crossbeam steel plate, the upside of the right side wall of described right side steel plate is welded with right crossbeam steel plate, the leading flank of left crossbeam steel plate and right crossbeam steel plate and the rear wall of front cross rail steel plate are welded and fixed.
The utility model is further set to: the left and right sides of described the first joist steel plate is provided with recess, is drilled with respectively the corresponding through hole one in position with recess on described arranged on left and right sides steel plate.
The utility model is further set to: the rear side of described the first joist steel plate is drilled with through hole two.
The utility model is further set to: the thickness of described front cross rail steel plate is 20mm, and the thickness of described arranged on left and right sides steel plate is respectively 25mm, and the thickness of described the first joist steel plate is 20mm.
The utility model is further set to: the maximum yield stress of described the first beam assembly is (5.9e+007) N/m2, and maximum displacement is 0.282mm, and minimum safety factor is 2.35.
By adopting technique scheme, the technique effect that the utility model reaches is: it is 60000N that present design makes the maximum bearing load of the front cross rail of the first beam assembly, left, the bearing load in two holes of right side board is respectively 15000N, the bearing load in the first beam hole is 12000N, in current the first traditional beam assembly of the sheet material using in this programme, use the thin 5mm-7mm of sheet material, material has also obtained very large saving accordingly, and the maximum yield stress that the first beam assembly produces under design maximum load working condition is (5.9e+007) N/m2, much smaller than the yield strength that forms the first beam assembly steel plate, maximum displacement is 0.282mm, minimum safety factor is 2.35, these two indexs all meet design requirement.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is one of perspective view of the present utility model.
Fig. 2 is two of perspective view of the present utility model.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, for disclosed a kind of tractor truck the first beam assembly of the utility model, the downside of the rear wall of front cross rail steel plate 10 is welded with the first joist steel plate 11 perpendicular to front cross rail steel plate 10, the left and right sides of the rear wall of front cross rail steel plate 10 is welded with respectively perpendicular to the left side steel plate 12 of front cross rail steel plate 10 and right side steel plate 13, downside respectively with the first joist steel plate 11 of the left side right side wall of steel plate 12 and the left side wall of right side steel plate 13 is by being welded and fixed, the left and right sides of described the first joist steel plate 11 is provided with recess 16, a described left side, right both sides steel plate 12, on 13, be drilled with respectively the corresponding through hole 1 in position with recess 16.The rear side of described the first joist steel plate 11 is drilled with through hole 2 18.
In above-mentioned, the upside of the left side wall of described left side steel plate 12 is welded with left crossbeam steel plate 14, the upside of the right side wall of described right side steel plate 12 is welded with right crossbeam steel plate 15, and left crossbeam steel plate 14 is welded and fixed with the leading flank of right crossbeam steel plate 15 and the rear wall of front cross rail steel plate 10.
In above-mentioned, the thickness of described front cross rail steel plate 10 is 20mm, and the thickness of described arranged on left and right sides steel plate 12,13 is respectively 25mm, and the thickness of described the first joist steel plate 11 is 20mm.The maximum yield stress of described the first beam assembly is (5.9e+007) N/m2, and maximum displacement is 0.282mm, and minimum safety factor is 2.35.
