Abstract
The invention discloses an automobile brake drum achieving fan heat dissipating. The automobile brake drum comprises a brake drum body, a wide reinforcing rib surface, an outer circle surface, outer fan blades, an inner circle transition surface, inner fan blades and heat dissipating structures. The automobile brake drum is characterized in that the outer fan blades are installed on the wide reinforcing rib surface and the outer circle surface of the brake drum body, the inner fan blades are installed on the inner circle transition surface, and the heat dissipating structures are arranged on the outer circle surface of the brake drum body. The automobile brake drum has the advantages that when the automobile brake drum bakes to decelerate, the fan blades rotate along with the brake drum body to enhance air convection around the brake drum body, exchanging of heat and air on the surface of the brake drum body is accelerated, and therefore the temperature generated when the brake drum brakes is lowered; meanwhile, by means of the heat dissipating structures, the heat dissipating property of the brake drum is improved, fan heat dissipating and cooling effects are achieved, hot cracking is prevented, the service life of the brake drum is prolonged, and the brake drum is completely superior to the national standard requirements.
Description
Technical field
The invention belongs to technical field of automobile parts and in particular to a kind of pectinid radiating automobile brake drum.
Background technology
Brake drum is the important component part of automobile brake assembly, and its performance quality directly affects the safety of car load,
And the important failure forms of aerial of brake drum is abrasion, is cracked, ftractures etc..Brake drum produces substantial amounts of heat with the friction of iron heel clutch-plate
So that the work surface temperature of brake drum is constantly raised, and both frictions mostly are mottled contact, the heat that contact surface produces because of friction
Measure and undergo phase transition, produce transformation stress, and the uneven also generation stress being heated, so that brake drum mechanical property is not
Uniformly, under frequently brake load, crack, increasing and extend with crackle, form pattern cracking.It is cracked out simultaneously
After now, under thermal stress and transformation stress act on, because local strength of tissue inter-variable declines, under 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.
At present, most of heavy-duty commercial vehicle, is using steam drum formula brake assembly, has that structure is simple, the spy of reliable operation
Point.Continuous development with automotive engineering and face different clients demand, automobile constantly at a high speed, heavy duty, frequently braking etc.
Many-side develops, and mountain highway comes into operation and congested in traffic aggravation in a large number, and these all make brake in frequent work
When making, the local temperature of brake drum can be higher, makes brake drum be in serious heat exhaustion state.In the past under the conditions of low speed underloading
Show fair brake drum service life to substantially reduce.And the security requirement more and more higher to automobile for the people, meet at a high speed,
On the premise of heavy duty, also safety be disclosure satisfy that, ruggedness and ride comfort requirement.
How to radiate and reduce the brake temperature of brake drum, prevent brake drum to be in heat exhaustion state, prevent Thermal cracking, extend
Service life, this is the key technology method solving brake drum cracking.

Content of the invention
The purpose of the present invention is to overcome prior art not enough, provides one kind can meet high speed, heavy duty, frequently brake, rigidity
By force, intensity is high, has significant pectinid cooling-down effect, effectively prevents Thermal cracking, long service life, brake is steady, safe and reliable
Pectinid radiating automobile brake drum.
The technical solution of the present invention is such that a kind of pectinid radiating automobile brake drum, including brake drum body, outward
Pectinid blade, interior wing air blade, periphery, radiator structure, wide reinforcement face, inner circle transition face it is characterised in that brake drum this
Exterior wing air blade (4) is provided with the wide reinforcement face (2) of body (1) and periphery (3), inner circle transition face (5) is provided with interior wing
Air blade (6), the periphery (4) of brake drum body (1) has radiator structure (7).
Exterior wing air blade (2) become left-handed to and/or dextrorotation be arranged on brake drum body (1) to pectinid.
Exterior wing air blade (2) has more than a piece of.
Brake drum body (1) is automobile brake drum.
The brake drum body (1) installing exterior wing air blade (2) is arranged on vehicle right and left side.
Interior wing air blade (6) and exterior wing air blade (4) are the fan balde structures revolving shape outer plate and/or oblique, its chi
Very little size sets according to brake drum model.
The present invention prominent effect compared with prior art is: during brake deceleration, pectinid blade turns together with brake drum
Dynamic, strengthen the cross-ventilation of brake drum periphery, accelerate the heat of brake drum surface and the exchange of air, when reducing brake drum brake
Temperature, simultaneously radiator structure improve brake drum heat dispersion, play the effect of pectinid radiating and cooling, prevent Thermal cracking, extend system
Dynamic drum service life, is completely superior to national standard and requires.
