Technical field
The invention belongs to vehicle anticollision technical fields, and in particular to aluminium alloy front beam.
Background technology
The support of front beam general action water tank and motor head, with left and right bottom bracket connect and compose frame so as to
Ensure that automobile there are enough torsion stiffness, main body is stamped to form by steel, is welded with small rack above, increases fixed position point, outside
Surface electrophoretic process carrys out anti-corrosion.
However, existing front beam existing defects to some extent, mainly:Steel density is big, is unfavorable for the power of automobile
Property and fuel economy;Steel are easily corroded, and surface needs to carry out electrophoretic process, so as to increase environmental pollution;Front beam is by ground
After the scrapings such as the sandstone of upper splashing, the electrophoretic paint layer on surface is easily broken.Steel exposes in air, by air corrosion, reduction of getting rusty
Product service life;It mostly protects and welds using two during welding, can form nonconducting filemot oxide-film on overland route, cause electrophoresis not
It is good, influence the appearance of product.It deals with extremely difficult and of high cost.
The content of the invention
The present invention is directed to the situation of the prior art, provides a kind of aluminium alloy front beam.
For the present invention using following technical scheme, the aluminium alloy front beam includes front beam body, aluminium profiles block, side reinforcement
Block, first support and second support;
Strengthen block welding with side simultaneously in the both ends end of the front beam body;
The top surface of the front beam body is recessed inwardly to form groove, and the aluminium profiles block is embedded in above-mentioned groove and and aluminium
Type block welding;
The side of the first support and front beam body is integrally formed, the second support simultaneously with front beam body
Above-mentioned side is integrally formed.
According to above-mentioned technical proposal, the quantity of the first support is 2, and the quantity of the second support is 3.
According to above-mentioned technical proposal, the second support is equally spacedly arranged at the length direction of the front beam body.
According to above-mentioned technical proposal, the first support has the first location hole and the second location hole, first positioning
Hole is for installing water tank, and for second location hole for installing radiator, the second support is described for installing front bumper
Aluminium profiles block is used to install bottom bracket.
According to above-mentioned technical proposal, the cross-section structure of the front beam body is in day font, and the two of the front beam body
End integrally extends to form protrusion respectively.
According to above-mentioned technical proposal, the second support be equipped with bolt, the second support have bending section, straightway,
Bevel edge section and fitting section, the bending section, straightway and bevel edge section are integrally formed, the both ends end of the fitting section respectively with directly
Line segment and bevel edge section are integrally formed.
According to above-mentioned technical proposal, the fitting section and the protrusion of front beam body of the second support are welded to each other.
Aluminium alloy front beam disclosed by the invention, its advantage be, compared with steel crossbeam can loss of weight about 34%, have
Relatively low automotive dead weight is imitated, improves the power performance and the economy performance of automobile;The preferable Anticorrosive Character of aluminium alloy is made full use of, is led to
Crossing the dense oxidation film on surface prevents by atmosphere environment corrosions such as acid rains.
