Description

A kind of aluminum-steel hybrid subframe

Technical field

This utility model is related to technical field of automobile, particularly to a kind of aluminum-steel hybrid subframe.

Background technology

The subframe of existing automobile typically adopts steel design and aluminum alloy materials to make, and is made using Steel material, product Assembled by discrete original paper, quality is big, oil consumption is high, need between original paper to be welded, mounting process is loaded down with trivial details, using welding Mode, the more difficult control of Product Assembly size, dimensional accuracy is not relatively high, it is impossible to be recycled after original paper corrosion is impaired, Cause the waste of resource.

And having using aluminum alloy materials that density is little, formability is good, the feature of excellent corrosion resistance, weight is relatively low, reduces Oil consumption, is conducive to advancing automobile industry energy-saving and emission-reduction；But aluminum alloy auxiliary vehicle frame processing and forming is relatively costly, in a large number using aluminum Alloy material, the cost of the product of raising, it is unfavorable for cost-effective.

Utility model content

Technical problem to be solved in the utility model is, for above-mentioned deficiency of the prior art, to provide a kind of steel aluminum Mixing subframe.Combined using steel and aluminium alloy and make subframe, effectively mitigate quality, reducing energy consumption, the precision that ensures, reduction Cost.

This utility model solves its technical problem and be employed technical scheme comprise that：

A kind of aluminum-steel hybrid subframe, including：Steelwork and articles made of aluminium alloy, the two ends setting of described steelwork 1 is installed Platform, described erecting bed arranges the first pilot hole, the two ends setting assembling groove of described articles made of aluminium alloy, on described assembling groove Second pilot hole is set, and described first pilot hole and the second pilot hole are connected by securing member, described first pilot hole and second Sleeve pipe is also set up on pilot hole.

Further, described securing member is bolt.

Further, described steelwork is integrated cast structure, and described articles made of aluminium alloy is integrated cast structure.

This utility model compared with prior art has advantages below：

In this utility model embodiment, using the subframe of steel and aluminium alloy making, wherein articles made of aluminium alloy is structure Complicated and have matching requirements the auxiliary frame structure part concentrated, improve assembly precision, reduce product weight, effectively reduce Energy consumption；Also more convenient for later stage recycling.Steel design is no assembling structure or the simple subframe of assembling structure Structure division, effectively reduces cost and production cycle, improves production efficiency.

In this utility model embodiment, using aluminum-steel hybrid subframe, combination steel that can be highly efficient, aluminium alloy Advantage, the density of aluminum is only the 1/3 of steel, can effectively reduce weight, reducing energy consumption using aluminum-steel hybrid subframe；Ensure While precision, reduce the complexity of technique；The different material of different structure application, effectively meets the same of functional requirement When, advantage of lower cost.For vehicle performance, MAT'L recycling rate, product lightweight, reducing energy consumption, advance low-carbon environment-friendly Life style have extraordinary important meaning.
