Body enters, but the serious wear of rubber pad influences vehicle frame reliable durable, and making vehicle, there are security risks.
Utility model content
The utility model to overcome above-mentioned the deficiencies in the prior art, provides a kind of medium-heavy automobile vehicle rack pipe crossbeam dress
It sets, frame strength and anti-twisting property can not only be improved, and can effectively solve the cavity ponding problem that vehicle frame japanning occurs,
And there is low, at low cost, high reliablity the beneficial effect of self weight.
The technical scheme adopted by the utility model is
A kind of medium-heavy automobile vehicle rack pipe beam device, including a round tube, two cappings and two connecting plates；Its
In,
Two cover and are respectively welded at the both ends of the round tube, two connecting plates respectively with both ends of the round tube and corresponding
Capping is welded, and offers several mounting holes in the circumferential direction of each connecting plate, for connecting with longitudinal beam.
The utility model, which further improves, to be, petal-shaped protrusion that there are two the end surface symmetric settings of connecting plate, two
Raised round mouth and drain mortise are formed between petal-shaped protrusion.
The utility model, which further improves, to be, connecting plate uses punch forming sheet metal component.
The utility model, which further improves, to be, the both ends of round tube are inserted into respectively in the raised round mouth for being correspondingly connected with plate
After weld.
The utility model, which further improves, to be, connecting plate is rectangular-shaped connecting plate.
The utility model, which further improves, to be, the quadrangle of connecting plate offers rounded corner.
The utility model, which further improves, to be, round tube is fabricated using cold-drawing seamless tube or welded still pipe cold-drawn
Manufacture and, steel pipe inner and outer surfaces do not have crackle, fold and scab.
The utility model, which further improves, to be, is covered as round sheet metal component.
The utility model has following beneficial technical effect:
A kind of medium-heavy automobile vehicle rack pipe beam device provided by the utility model, including a round tube, two cappings
With two connecting plates；Wherein, capping is welded with round tube, can not be flowed out or be flowed out after solution capable of being effectively prevent to enter round tube and is slow
Slowly, connecting plate is connect by mounting hole with longitudinal beam, and round tube and connecting plate weld at round tube capping, connecting plate two, compared with
It is bigger that common tube beam only welds the form intensity at one.
Further, the end face part of connecting plate is petal-shaped bulge-structure, keeps connecting plate equal compared with ordinary flat stress
It is even, raised round mouth and drain mortise are formed between petal-shaped protrusion, it is intracavitary that drain mortise can be released effectively petal-shaped bulge-structure
Liquid.
Further, connecting plate is punch forming sheet metal component, can reasonable layout stress, and can be released effectively intracavitary molten
Liquid improves painting quality.
Further, round tube is that cold-drawing seamless tube manufactures or welded still pipe cold-drawn manufactures, and steel pipe inner and outer surfaces, which must not have, to be split
Line is folded and is scabbed, and has weldability energy.

Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of medium-heavy automobile vehicle rack pipe beam device provided by the utility model, including a round tube
1, two cappings 2 and two connecting plates 3；Wherein, two cappings 2 are respectively welded at the both ends of the round tube 1, and two connecting plates 3 divide
It is not welded with the both ends of the round tube 1 and corresponding capping 2, offers several mounting holes 301 in the circumferential direction of each connecting plate 3,
For being connect with longitudinal beam.
When components produce, as shown in Fig. 2, connecting plate 3 is stamping, make its perfect flower petal-like protrusion 302 and drain
Slot 303, and circular open is gone out at 3 center of connecting plate, so that connecting plate 3 can be welded effectively with round tube 1.Petal-shaped protrusion
302 can rationally be uniformly distributed the stress that connecting plate 3 is subject to, and improve part reliable durable.Intake chute 303 can effectively export connection
