Description

Aluminum-clad iron bearing support

Technical Field

The utility model relates to a bearing bracket field specifically is an aluminium package iron bearing bracket.

Background

The middle support of the driving shaft, called bearing bracket for short, plays a role in supporting the middle shaft of the driving shaft. The NVH performance is improved, but the existing bearing support is basically made of iron/steel or aluminum. The structural performance of the iron/steel part can meet the use requirement, but the iron/steel part has heavier weight, is easy to rust and has high price; although the aluminum product has light weight, low price and no rust, the aluminum product has poor strength, is easy to shake and make abnormal sound, and the service performance is influenced by environmental change.

Disclosure of Invention

In order to solve the problem, the utility model provides an aluminium package iron bearing bracket.

An aluminum-clad iron bearing support comprises an iron piece in direct contact with a driving shaft and an aluminum piece support connected with the iron piece in a high-pressure die-casting mode.

The excircle of iron member on be provided with the concave keyway of cross concave into.

And a convex key which is matched with the key groove and protrudes from the cross shape is arranged on the aluminum part bracket.

The utility model has the advantages that: with the combination of aluminium alloy support, ironware organic, integrated both sides' advantage: the NVH performance is improved, the cost is reduced, the rust is avoided, the price is reduced, the inherent defects of the independent aluminum piece and the independent iron piece are creatively overcome, the product types of the industry are enriched, and the product competitiveness is improved.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic perspective view of the present invention;

FIG. 2 is a schematic view of a three-dimensional structure of an aluminum support of the present invention;

fig. 3 is a schematic view of the three-dimensional structure of the iron member of the present invention.

Detailed Description

In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, and the utility model is further explained below.

As shown in fig. 1 to 3, an aluminum clad iron bearing bracket includes an iron member 2 directly contacting with a driving shaft, and an aluminum member bracket 1 connected with the iron member 2 by high pressure die casting.

Combine aluminium part support 1, 2 organic of ironware, integrated both sides' advantage: the NVH performance is improved, the cost is reduced, the rust is avoided, the price is reduced, the inherent defects of the independent aluminum piece and the independent iron piece are creatively overcome, the product types of the industry are enriched, and the product competitiveness is improved.

The excircle of the iron part 2 is provided with a concave keyway 21 which is concave in a cross shape, and the part is contacted with the aluminum part bracket 1.

The aluminum part bracket 1 is provided with a convex key 11 which is matched with the key groove 21 and protrudes in a cross shape.

The cross-shaped concave key groove 21 and the convex key 11. And all degrees of freedom are perfectly restricted, and the aluminum iron cannot move. Ensuring the reliability of the product

The iron part 2 and the aluminum part support 1 are connected together in a high-pressure die-casting mode: the iron part 2 is placed in a die, and high-temperature aluminum liquid is die-cast into the existing iron part die under high pressure to be directly formed.

The iron piece in the utility model can be replaced by a steel piece.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and what is described in the specification are the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the present invention, and these changes and modifications are intended to fall within the scope of the present invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.

Claims (3)
