Abstract
The invention relates to an automotive gear-box shifting fork material in melt material technique field. The each component and weight percentage are as following: 3.5-4.5%, Si:11-13%, Mg:0.45-0.65%, Zn:less than 1.5%, Fe:less than 1.0%, Mn:less than 0.5%, Ni:less than 0.3%, Sn:less than 0.3%, Al: allowance. The invention is used to make shifting fork, and prolong its using life.
Description
Technical field
What the present invention relates to is a kind of metallic substance technical field material, and specifically, what relate to is a kind of fork drawing material of automobile gear box.
Background technology
Shift fork is an important safety member in automobile gearbox, damages as occurring in exercising the way, and the tragedy of car crash will take place.Therefore, the material that is used to produce shift fork is a gordian technique.And the material of shift fork is a know-how in each manufacturer.
In the existing disclosed technology, generally adopt the ADC14 trade mark material of JISH5302-1990 to produce shift fork, but the intensity extensibility of this material and impelling strength are not high, σ b≤180N/mm2, δ≤0.5%, HB 〉=90, behind the frequent use shift fork, fracture causes the accident easily.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of fork drawing material of automobile gear box is provided, make its intensity and the impelling strength that increase shift fork, prolong the work-ing life of shift fork.Make the automobile shift fork with this material, can prolong the work-ing life of shift fork.
The present invention is achieved by the following technical solutions, and each component of the present invention and weight percent are:
Cu：3.5～4.5％，
Si：11～13％，
Mg：0.45～0.65％，
Zn：≤1.5％，
Fe：≤1.0％，
Mn：≤0.5％，
Ni：≤0.3％，
Sn：≤0.3％，
All the other are Al.
The present invention obtains in the following manner, fusing into each composition in proportion after the aluminium fusing, is poured into the mould of shift fork, through the pressure die casting moulding earlier.Cast temperature is 650 ℃～690 ℃.
Performance of the present invention improves a lot: σ b 〉=260N/mm2, δ 〉=1.2%, HB 〉=90.For intensity and the impelling strength that improves fork drawing material of automobile gear box, increase the security of automobile, the present invention is used to produce shift fork, replaces the metallic substance of existing conventional.At four/five grades of hand shifts, switching speed: the useful effect that 15～18 times/minute, 3500 rev/mins (transmission output speed) obtains is: after the old material gear shift of prior art 1000 times, rupture, and after the novel material gear shift of the present invention 12000 times, still as excellent as before.
