The working face temperature of brake drum is set constantly to raise, and both frictions are generally mottled contact, the heat that contact surface is produced by friction
Measure and undergo phase transition, produce transformation stress, and it is heated it is uneven also produce stress so that brake drum mechanical property is not
Uniformly, under frequently brake load, crack, increasing and extending with crackle, form pattern cracking.It is cracked out simultaneously
After now, under thermal stress and transformation stress effect, because local strength of tissue inter-variable declines, in the case where frequently braking, Yi Jiyi
A little users install water drenching device additional, make brake drum surface temperature decrease so that crackle constantly extends, and form serious crackle and cause out
Split.It is brake drum insufficient strength itself in addition, causing another major reason that defective drum ftractures, mainly production is made
The material selected during dynamic drum is poor, and the content of chemical element is undesirable, and mechanical property is not up to standard, there is casting flaw, casting
Stress is excessive.
At present, most of heavy-duty commercial vehicle, is to use drum brake assembly, the characteristics of with simple in construction, reliable operation.
Continuing to develop and face different clients demand with automotive engineering, automobile constantly at a high speed, heavy duty, frequently braking etc. it is multi-party
Face is developed, and mountain highway largely comes into operation and congested in traffic aggravation, and these all cause brake in frequent operation,
The local temperature of brake drum can be higher, brake drum is in serious heat fatigue state.Showed in the past under the conditions of low speed underloading
Fair brake drum service life is substantially reduced.And people are meeting high speed, heavy duty to the security requirement more and more higher of automobile
On the premise of, it also disclosure satisfy that security, durability and ride comfort requirement.
How to prevent that brake drum from producing Cracking Failure because of reasons such as intensity is not enough, heated phase transformations, this is one to annoying vapour
The problem of car brake drum manufacturing.

Scheme is different with technical characteristic.
The content of the invention
The purpose of this utility model is to overcome prior art deficiency there is provided ferro-aluminum composite brake drum, and it can be significantly improved
The intensity and rigidity of brake drum, with significant radiating and cooling effect, effectively prevent Thermal cracking, weight saving, long service life,
Improve the security reliability used.
Technical solution of the present utility model is such：A kind of ferro-aluminum composite brake drum, including brake drum body
（1）, aluminium alloy radiator structure layer（2）, compound interface（3）, it is characterised in that brake drum body（1）One layer is combined on periphery
Aluminium alloy radiator structure layer（2）, aluminium alloy radiator structure layer（2）With brake drum body（1）Between have compound interface（3）, aluminium conjunction
Golden radiator structure layer（2）With brake drum body（1）For consubstantiality.
Brake drum body（1）Structure be the structure for including automobile brake drum brake lining.
Brake drum body（1）It is cast iron.
Aluminium alloy radiator structure layer（2）There are more than one layer, aluminium alloy radiator structure layer（2）It is aluminum alloy materials.
Compound interface（3）It is the face of cylinder and/or variously-shaped curved surface.
The protrusion effect of the utility model compared with prior art is：The spy such as both kept the wear-resisting of cast iron, coefficient of friction high
Property, the density that also utilizes high-strength aluminum alloy is small, the characteristic that intensity is high, thermal conductivity is good, with significant radiating effect, mitigates
The weight of brake drum, improves the intensity of brake drum, while optimizing the heat dispersion of brake drum, accelerates braking during brake
Heat and air exchange, it is therefore prevented that the Thermal cracking that high temperature is produced, extend the service life of brake drum, efficiently solve brake drum
Using problem of Cracking, the requirement of automotive light weight technology is also more preferably met.It is completely superior to national standard requirement.
