Abstract
A cylindrical front beam of a heavy truck frame is formed by cutting a cylindrical steel tube. The left end and the right end of the front beam are inserted into large circular holes of connecting plates made of a steel plate respectively to be firmly welded, the positions between the upper portion and the lower portion of the left end of the front beam and one connecting plate and the positions between the upper portion and the lower portion of the right end of the front beam and the other connecting plate are respectively provided with a triangular reinforcing plate made of steel plates in a welding mode. Four circular holes are machined in the connecting plates, and welding-on part assemblies are connected to the inner side of a left longitudinal beam and the inner side of a right longitudinal beam in a riveting mode through four rivets via the four circular holes. The cylindrical front beam of the heavy truck frame has enough strength, and is easy to manufacture, light, small in windward area and smooth in surface, the shielding effect on the air flow coming from the front is small, the heat dissipation and ventilation of a radiator behind the front beam are facilitated, and the front beam can be widely applied to heavy trucks.
Description
Technical field
The utility model relates to automobile chassis frame manufacturing technology field, particularly the cylindrical front cross rail of a kind of heavy-duty truck vehicle frame.
Background technology
Heavy-duty truck longeron front end sectional dimension is larger, and the front cross rail generally adopting is at present the channel-section rail with Steel Sheet.Because the upper and lower aerofoil of front cross rail of flute profile need be connected with rivet with the upper and lower aerofoil of longeron, therefore front cross rail sectional dimension and quality are larger, wind area is also larger, and the air-flow that the place ahead is come has the larger effect of blocking, and is unfavorable for the heat dissipation ventilation of the radiator after it.
Utility model content
The utility model proposes the cylindrical front cross rail of a kind of heavy-duty truck vehicle frame, it can overcome the problems referred to above.
The cylindrical front cross rail of this heavy-duty truck vehicle frame that the utility model provides, front cross rail forms with round steel pipe blanking, the interior firmly welding of connecting panel big hole that steel plate is made is inserted respectively at left and right two ends, welds respectively the triangle brace panel that a block plate is made between upper and lower parts, front cross rail two ends and two connecting panels.On connecting panel, be processed with four circular holes, with four rivets, above-mentioned soldering member assembly be riveted on to left and right longeron inner side respectively.The cylindrical front cross rail of this heavy-duty truck vehicle frame has enough intensity, make simple, quality is less, wind area is also less, and its surface is round and smooth, the effect of blocking of the air-flow that the place ahead is come is less, is conducive to the heat dissipation ventilation of the radiator after it, can be widely used in heavy-duty truck.
Accompanying drawing explanation
Fig. 1 is the front elevation Ji Cong automotive front back projection of overall structure schematic diagram of the present utility model and the view that obtains.
Fig. 2 is the birds-eye view of overall structure schematic diagram of the present utility model.
Fig. 3 is that the K of Fig. 1 in the utility model is to view.
In Fig. 1～3, each label is: the left longeron of 1-, 2-connecting panel, 3-front cross rail, 4-rivet, 5-right vertical beam, 6-brace panel.
The specific embodiment
Below in conjunction with accompanying drawing, be elaborated.
As shown in Figures 1 to 3, the installation matrix of front cross rail---5 of left longeron 1 and right vertical beams represents with long and two-short dash line, does transparence and processes.The cylindrical front cross rail of this heavy-duty truck vehicle frame that the utility model provides, front cross rail 3 use round steel pipe blankings form, the interior firmly welding of connecting panel 2 big holes that steel plate is made is inserted respectively at left and right two ends, welds respectively the triangle brace panel 6 that a block plate is made between front cross rail 3 upper and lower parts, two ends and two connecting panels 2.On connecting panel 2, be processed with four circular holes, with four rivets 4, above-mentioned soldering member assembly be riveted on to left longeron 1, right vertical beam 5 inner sides respectively.The cylindrical front cross rail of this heavy-duty truck vehicle frame has enough intensity, make simple, quality is less, wind area is also less, and its surface is round and smooth, the effect of blocking of the air-flow that the place ahead is come is less, is conducive to the heat dissipation ventilation of the radiator after it, can be widely used in heavy-duty truck.
Claims (2)
1. the cylindrical front cross rail of heavy-duty truck vehicle frame, it is characterized in that, front cross rail forms with round steel pipe blanking, the interior firmly welding of connecting panel big hole that steel plate is made is inserted respectively at left and right two ends, welds respectively the triangle brace panel that a block plate is made between upper and lower parts, front cross rail two ends and two connecting panels.
2. the cylindrical front cross rail of heavy-duty truck vehicle frame as claimed in claim 1, is characterized in that, is processed with four circular holes on connecting panel, with four rivets, above-mentioned soldering member assembly is riveted on to left and right longeron inner side respectively.
