Abstract

A kind of brake drum for the perfect heat-dissipating that effectively heat energy caused by severe friction can be dispersed, greatly mitigate braking surface heat fading phenomenon, prevent braking surface from ftractureing, extend brake drum service life, it is made up of braking surface, the flange face being connected with braking surface, the reinforcing strip located at braking surface periphery, on the braking surface multigroup heat emission hole run through is circumferentially uniformly provided with close to flange face end, point to the axle center of brake drum, and two adjacent groups heat emission hole interlaced arrangement in the axle center of heat emission hole.

Description

The brake drum of perfect heat-dissipating
Technical field
The present invention relates to the drum brake for vehicle, particularly a kind of brake drum of perfect heat-dissipating.
Background technology
Brake drum is that one kind is connected with wheel hub, for realizing the device of brake with shoe brake collective effect, belongs to braking Vital part in device assembly, brake drum include braking surface and flange face, and the bolt hole on flange face passes through fastener with wheel hub Connection.Existing brake drum does not have heat emission hole or heat dissipation channel in braking surface, and braking surface and shoe brake are violent when causing to brake Friction, produces a large amount of heat energy, because heat energy caused by severe friction can not effectively disperse, causes braking surface heat fading phenomenon, makes Dynamic face cracking, influence the service life of brake drum.
The content of the invention
In order to solve the above-mentioned technical problem the present invention is, there is provided one kind effectively can disperse heat energy caused by severe friction, The system for the perfect heat-dissipating for greatly mitigate braking surface heat fading phenomenon, preventing braking surface from ftractureing, extend brake drum service life Dynamic drum.
The present invention technical solution be：
A kind of brake drum of perfect heat-dissipating, by braking surface, the flange face being connected with braking surface, located at braking surface periphery Reinforcing strip is formed, and it is characterized in that：On the braking surface close to flange face end be circumferentially uniformly provided with it is multigroup run through dissipate The axle center of brake drum, and two adjacent groups heat emission hole interlaced arrangement are pointed in hot hole, the axle center of heat emission hole.
Further, the heat emission hole is circle.
Further, the heat emission hole is changed to five groups, and two adjacent groups radiating pitch of holes is identical.
The beneficial effects of the invention are as follows：
The multigroup heat emission hole run through being circumferentially uniformly arranged close to flange face end on the braking surface, brake shoes and system Dynamic face friction produces amount of heat, and extraneous air enters brake drum inner chamber by heat emission hole, then heat is taken out of by heat emission hole To outside brake drum, so as to reach the purpose of radiating, braking surface heat fading phenomenon is greatly alleviated, it is therefore prevented that braking surface ftractures, Extend brake drum service life.And while heat emission hole is added, decrease the own wt of brake drum.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is Fig. 1 A-A sectional views；
In figure：1- braking surfaces, 2- flange faces, 3- reinforcing strips, 4- heat emission holes.
Embodiment
As illustrated, a kind of brake drum of perfect heat-dissipating, by braking surface 1, the flange face 2 being connected with braking surface 1, is located at The reinforcing strip 3 of the periphery of braking surface 1 is formed, on the braking surface 1 close to the end of flange face 2 be circumferentially uniformly provided with it is multigroup run through dissipate Hot hole 4, the heat emission hole 4 are circle, the axle center of the axle center sensing brake drum of heat emission hole 4, and two adjacent groups heat emission hole 4 staggeredly cloth Put, the heat emission hole 4 is changed to five groups, and the spacing of two adjacent groups heat emission hole 4 is identical.
When vehicle is braked, brake shoes is rubbed with braking surface 1, produces amount of heat, and extraneous air is entered by heat emission hole 4 Brake drum inner chamber, then heat is taken out of outside brake drum by heat emission hole 4, so as to reach the purpose of radiating.Reduce braking surface 1 The probability of cracking, so as to improve the performance of brake drum, meanwhile, while heat emission hole 4 are added, decrease braking Bulging own wt.
The specific embodiment of the present invention is these are only, is not intended to limit the invention, for those skilled in the art For member, the present invention can have various modifications and variations.Any modification within the spirit and principles of the invention, being made, Equivalent substitution, improvement etc., should be included in the scope of the protection.
