Abstract
The present invention relates to technical field of automobile parts more particularly to a kind of engine crankshafts.Requirement with consumer to car mass is higher and higher, and as critical component, simple conventional material is increasingly difficult to meet the requirement in terms of the service life engine crankshaft.The present invention is by being bonded metal layer and wear-resistant layer with adhesive layer, metal layer generates higher intensity by rational proportion elemental composition, wear-resistant layer uses wear-resistant material, so that the wearability and intensity of engine crankshaft all greatly improve, effectively extends the service life of engine crankshaft.Present invention is mainly used for engine crankshafts.
Description
Technical field
The present invention relates to technical field of automobile parts more particularly to a kind of engine crankshafts.
Background technique
In the manufacturing field of auto parts and components, steel and aluminium are widely applied as main material.As consumer is to automobile
The requirement of quality is higher and higher, and as critical component, simple conventional material is increasingly difficult to meet in service life side engine crankshaft
The requirement in face.
Summary of the invention
In order to solve the above technical problems, the object of the present invention is to provide a kind of using composite material and the hair good with wearability
Motivation crankshaft.
Technical scheme is as follows:
A kind of engine crankshaft, including metal layer, adhesive layer and wear-resistant layer；Metal layer is arranged in engine crankshaft
The outside of metal layer is arranged in portion, adhesive layer, and the outside of adhesive layer is arranged in wear-resistant layer；The chemical composition and quality hundred of metal layer
Divide ratio are as follows: manganese 0.6-0.15%, phosphorus≤0.02%, aluminium 0.004-0.09%, molybdenum≤0.03%, carbon 0.23-0.29%, chromium
0.03-0.5% and titanium 0.04-0.06%, remaining content are iron.
Further, the material of wear-resistant layer is aluminium oxide ceramics.
Further, wear-resistant layer with a thickness of 1-1.3mm.
Further, adhesive layer is inorganic oxide copper product.
The beneficial effects of the present invention are:
By the way that metal layer and wear-resistant layer are bonded with adhesive layer, metal layer is generated higher by rational proportion elemental composition
Intensity, wear-resistant layer use wear-resistant material, so that the wearability and intensity of engine crankshaft all greatly improve, effectively extend hair
The service life of motivation crankshaft.
Specific embodiment
With reference to embodiment, the embodiment of the present invention is furthur described in detail.Following embodiment is used for
Illustrate the present invention, but is not intended to limit the scope of the invention.
A preferred embodiment of the invention, the engine crankshaft, including metal layer, adhesive layer and wear-resistant layer；Metal layer
The inside of engine crankshaft is set, and the outside of metal layer is arranged in adhesive layer, and the outside of adhesive layer is arranged in wear-resistant layer；Metal
Layer chemical composition and mass percent are as follows: manganese 0.6-0.15%, phosphorus≤0.02%, aluminium 0.004-0.09%, molybdenum≤0.03%,
Carbon 0.23-0.29%, chromium 0.03-0.5% and titanium 0.04-0.06%, remaining content are iron, and the material of wear-resistant layer is aluminium oxide pottery
Porcelain, wear-resistant layer with a thickness of 1-1.3mm, adhesive layer is inorganic oxide copper product.
The above is only the preferred embodiment of the present invention, are not intended to restrict the invention, it is noted that this technology is led
For the those of ordinary skill in domain, without departing from the technical principles of the invention, several improvements and modifications can also be made,
These improvements and modifications also should be regarded as protection scope of the present invention.
