Description
Technical field
The utility model belongs to auto parts and components field, and in particular to a kind of spiral heat dissipation brake drum.
Background technology
Brake drum is the important component of automobile brake assembly, and its performance quality directly affects the security of vehicle,
And the important failure forms of aerial of brake drum is abrasion, cracking, cracking etc..Brake drum produces substantial amounts of heat with the friction of iron heel clutch-plate
The working face temperature of brake drum is set constantly to raise, temperature can be more than 500 DEG C, and both frictions are generally mottled contact, contact
Face is undergone phase transition because of the heat that friction is produced, and produces transformation stress, and it is heated it is uneven also produce stress so that system
It is dynamic to rouse the uneven of mechanical property, under frequently brake load, crack, increasing and extending with crackle, form net
Shape crackle.It is cracked simultaneously after occurring, under thermal stress and transformation stress effect, because local strength of tissue inter-variable declines, in frequency
Under numerous braking, and some users install water drenching device additional, make brake drum surface temperature decrease so that crackle constantly extends, and are formed
Serious crackle causes cracking.
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.
Temperature during brake drum brake how is reduced, prevents that brake drum from producing phase transformation because of high temperature, this is to solve brake drum to make
The key technology method failed with Thermal cracking.
