Description
Technical field
The present invention relates in general to a kind of lining that is used for fixing the automobile ABS transmitter, and the beryllium bronze alloy material especially for making lining belongs to the copper base alloy field.
Background technology
At present, in the various safety equipment of equipping on automobile, ABS (ABS (Anti-lock Braking System)) is most widely used general, and transmitter is the vitals of ABS, and transmitter fixed mode can influence the measuring accuracy of system.
The fixed form of transmitter in fixed support generally has two kinds, and a kind of is that support bracket fastened diameter of bore can shrink by trace, because diameter of bore equals the transmitter external diameter, during sensor installation, after set up the clearance, available holding bolt shrank shelf inner diameter and clamps transmitter; Another kind is to rely on spring bushing, and transmitter is fixed in the support bracket fastened endoporus.The former needs very important person's wage adjustment to put in order the clearance, install the back transmitter and be difficult for becoming flexible, but this brings certain difficulty to installation; But the clearance self-regulated in latter's fixed form, assembling is simple, and is safe and reliable, easy to maintenance.That second kind of fixed form is mainly used in is economical and practical, on the mechanical type ABS of highly versatile, mainly be used on the commercial car, and wherein important part is exactly an elastic lining.
Here, lining mainly has been a fixed action, and since the clearance in the fixed form can be from tonality, it is particularly important that elasticity seems, and wearing and tearing also are inevitably, so lining must have good elasticity, wear resistance and consistence; Owing to work near wheel, environment is abominable, can produce high temperature in the braking procedure, so it also will have characteristics such as high temperature resistance, anti-electrostatic, corrosion stability; In addition owing to ABS ECU and transmitter to its connect influence that lead is subject to electromagnetic field work not normal, so lining will have the effect of anti-electromagnetic interference.
Berylliumbronze has excellent mechanical property, physicals and chemical stability, it is a kind of important resilient material, it has characteristics such as tensile strength is big, fatigue resistance is high, high thermal resistance is good, corrosion resistance is strong, good moldability, have good electrical conductivity, thermal conductivity and thermal diffusivity, also have nonmagnetic, do not produce advantages such as spark when being hit.Plurality of advantages has determined that berylliumbronze is a preferred material of making elastic lining.
The berylliumbronze lining intensity of domestic production on the market is not high, and work-ing life is lower, has not given play to the advantage of berylliumbronze, mainly be that technology is not mature enough, Given this because the proportioning of material is not ideal enough, need provide a kind of new high performance material, meeting the market requirement.
Summary of the invention
The objective of the invention is to, a kind of good springiness, intensity height are provided, be applicable to the beryllium bronze alloy material of abs sensor lining.
The invention provides a kind of beryllium bronze alloy material, by weight percentage, this alloying constituent is a beryllium: 1.8～2.5%, cobalt: 0.15～0.3%, aluminium: 0.01～0.05%, iron: 0.01～0.05%, nickel: 0.001～0.01%, zinc: 0.01～0.1%, unavoidable impurities＜0.001%, surplus are Cu.
The present invention is realized by following four kinds of preferred versions:
A kind of optimal technical scheme is characterized in that: the copper in the described beryllium bronze alloy material, beryllium, cobalt total amount are not less than 99.5%;
A kind of optimal technical scheme is characterized in that: also contain 0.01～0.05% aluminium and iron in the described beryllium bronze alloy material;

A kind of optimal technical scheme is characterized in that: also contain in the described beryllium bronze alloy material and be no more than 0.001%～0.01% nickel;
Function and reason to other element of adding in the alloy of the present invention describes below:
Described sensor bush beryllium bronze alloy material, be to utilize the characteristic that is distributed in intracrystalline and crystal boundary that beryllium, cobalt and intermediate compound thereof can even dispersion, and make that by processing and thermal treatment the distribution of alloy is more even, not only improve hardness of alloy and elasticity, and improved its over-all properties greatly;
Add cobalt in the beryllium bronze alloy material of described sensor bush and mainly be in order to increase matrix strength, to improve wear resistance, make the higher toughness of alloy tool, and reduce the sensitive property of impact, its total body burden is not less than 0.15%;
Add aluminium in the beryllium bronze alloy material of described sensor bush and mainly be in order to improve mechanical property and the oxidation-resistance of alloy under room temperature and high temperature, its total body burden is no more than 0.05%;
The effect of adding nickel in the beryllium bronze alloy material of described sensor bush mainly is that beryllium forms intermediate compound, increases matrix strength, and the effect of stress corrosion resistant is arranged, and its total body burden is no more than 0.01%;
The effect of adding zinc in the beryllium bronze alloy material of described sensor bush mainly is that it improves its plasticity effect, and its total body burden is no more than 0.1%;
The effect of adding iron in the beryllium bronze alloy material of described sensor bush mainly has been the effect of crystal grain thinning, stops growing up of crystal grain, and also can play the effect that improves its high temperature softening resistance energy, and its total body burden is no more than 0.05%.
