Abstract
The present invention relates to a kind of engine links, and in particular to a kind of connection rod of automobile engine belongs to technical field of automobile parts.Engine link is mainly made of the raw material components of following mass fraction：58 parts of silica flour, magnesium powder：0.2 0.8 parts, 0.15 0.35 parts of iron powder, 0.02 0.04 parts of copper powder, 0.01 0.04 parts of zinc powder, 0.008 0.03 parts of manganese powder, TiB20.5 2 parts of particle, CeO20.1 0.3 parts of powder, Y2O50.1 0.3 parts of powder, 85 95 parts of aluminium powder.The metal powder of inventive engine connecting rod rational proportion connecting rod, match somebody with somebody hot compacting again, and specific modified coating, then the heat treatment by lower temperature are coated in rod surface, collective effect improves hardness, intensity, wearability and the corrosion resistance of engine link.
Description
Technical field
The present invention relates to a kind of engine links, and in particular to a kind of connection rod of automobile engine belongs to auto parts and components skill
Art field.
Background technology
The major part of connecting rod is connected with the crank-pin of bent axle, and major part generally makees dissection type, is known as connecting rod cap by separated part,
Special connecting-rod bolts are connect to be fastened on the major part of connecting rod.Major part hole surface has very high finish, so as to tight with connecting rod bearing shell
It is closely connected and.Big end is also milled with positioning pit, and the big end of connecting rod also has hole.Connecting rod is as the critical piece extensive use for transferring power
In on all kinds of power vehicles, being the important component of all kinds of diesel engines or gasoline engine.Engine link is held during power is transferred
By very high periodic shock power, inertia force and bending force.This requires engine link should have very high intensity, wear-resisting
