Description
Technical field
Motor-car accessory technical field is the utility model is related to, specially a kind of aluminum-base composite motor vehicle brake disk.
Background technology
With the development of science and technology the speed of high-speed railway is constantly improved, the use condition of its braking device
Also increasingly harsher, people are also constantly improving to its performance requirement, and this requires that braking device will cause in the short time
High ferro is stopped, and this kinetic energy that high ferro can be made huge changes into the frictional heat energy of braking brake block, and surface of friction pair temperature is drastically
Rise, so influence whether the coefficient of friction of friction material so that security, the reliability of high ferro reduce, for current brake
Hull, its main heat dissipation design are that the cylindrical heat-radiating through hole through disk body is opened up on disk body, so as to increase dissipating for disk body
Hot face, however, in fact in brake disc rotary course, the pressure on both sides is suitable, therefore, air flow in thermal vias compared with
Small, its radiating efficiency can not play efficiently, can be produced during frictionally, between brake block and brake disc certain
Dust, and the attachment of these caused dusts is on the surface, so as to form rolling friction between brake block and brake disc, causes to stop
Frictional force between car piece and brake disc reduces, and then has influence on braking effect.
Utility model content
The purpose of this utility model is to provide a kind of aluminum-base composite motor vehicle brake disk, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides following technical scheme：A kind of aluminum-base composite motor vehicle brake disk, including
Sleeve and disk, sleeve are fixedly connected with disk, and the sleeve flushes through disk and the lower surface of sleeve with the bottom surface of disk,
The disk includes the first panel surface and the second panel surface, passes through some cylinders between first panel surface and the second panel surface
Shape gusset is fixedly connected, and forms heat dissipation channel between the adjacent cylindrical gusset, and the disk is provided with bolt hole, and described
One panel surface and the second panel surface are equipped with the recessed grain of bar shaped, and thermal vias is provided between the recessed grain of two adjacent parting bead shapes.
Preferably, the thermal vias is taper type hole, and the thermal vias is perpendicular to disk and just puts inverted mutual
It is arranged alternately in the first panel surface and the second panel surface.
Preferably, the sleeve is provided with seam, and through hole is additionally provided with the sleeve.
Preferably, first panel surface and the second panel surface are equipped with friction lug.
Compared with prior art, the beneficial effects of the utility model are：First panel surface and the second dish cart in the present invention
Face is fixed by several cylindrical gussets and forms heat dissipation channel, and the first panel surface and the second panel surface are equipped with radiating
Through hole, above design improve the radiating effect of brake disc in use so that the heat energy of brake disc friction generation
Disperse in time, avoid brake disc because frictional heat is excessive and temperature distortion, the service life of brake disc is improved, in addition, first
Panel surface and the second panel surface also have strip groove, because of dust caused by friction, during brake block and brake disc roll
It is swept into strip groove and is distributed to by strip groove in air, so as to reduce attachment of the dust in brake panel surface, is improved
Braking effect.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model cross-sectional.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
Fig. 1-2 is referred to, the utility model includes sleeve 2 and disk 1, and sleeve plays axially position, and disk is to make system
Moving calipers produce brake force by friction plate clamp circle disk makes motor-car slow down or stop：Sleeve and disk use aluminum-base composite material
Material, its feature such as light weight, density is small, plasticity is good, and aluminum matrix composite specific strength and specific stiffness are high, and high-temperature behavior is good, more
Endurance and wear-resisting, damping capacity is good, and thermal coefficient of expansion is low, the same with other composites, it can combine specific mechanics and
Physical property, to meet the needs of product, therefore, aluminum matrix composite has turned into the most frequently used, most in metal-base composites
One of important material；Sleeve 2 is fixedly connected with disk 1, and sleeve 2 is through the lower surface of disk 1 and sleeve 2 and the bottom of disk 1
Face flushes, and power transmission shaft passes through the endoporus of sleeve：Disk 1 includes the first panel surface 10 and the second panel surface 8, the He of the first panel surface 10
It is fixedly connected between second panel surface 8 by some cylindrical gussets 9, heat dissipation channel is formed between adjacent cylindrical gusset 9,
The effect of quick heat radiating can be played：Disk 1 is provided with bolt hole 6, and disk is fixed on power transmission shaft by bolt by bolt hole, right
Disk carries out warp-wise positioning, prevents disk with respect to drive axis：It is recessed that first panel surface 10 and the second panel surface 8 are equipped with bar shaped
Grain 5, groove make friction plate be fallen to powder caused by disk high-speed friction in groove, produced when then passing through disc rotary
Centrifugal force the powder in groove thrown away into out disk so as to reduce attachment of the powder in brake panel surface, can effectively avoid because
Rolling friction caused by powder between brake block and brake disc, and then the friction example between brake block and brake disc is improved, most
Braking effect is improved eventually：Thermal vias 7 is provided between adjacent two bar shapeds recessed poor 5, thermal vias is mistake of the disk in rotation
Have in journey it is distinguished and admirable enter heat emission hole in the radiating effect that desuperheat improves disk is carried out to disk, substantially increase disk and power transmission shaft
Service life.
In the present embodiment, thermal vias 7 is taper type hole, and thermal vias 7 is perpendicular to disk 1 and is just putting inverted mutually friendship
For being arranged in the first panel surface 10 and the second panel surface 8, thermal vias be designed to taper type be for brake disc when rotated,
Due to aerodynamic principle, air forms pressure difference and eddy flow in cone machine hole, accelerates the radiating effect of frustum hole surface,
So as to improve the brake safe performance of the service life of brake disc and motor-car, because the big path of taper hole is arranged alternately with each other in disk
On body, the radiating of brake disc both side surface is visibly homogeneous, will not produce the situation of amount of localized heat aggregation.
In the present embodiment, sleeve 2 is provided with seam 3, and through hole 11 is additionally provided with the sleeve 2, and it is conveniently to cover to set seam
Cylinder axially position, the through hole on sleeve is to increase the radiating effect of power transmission shaft.
In other the present embodiment, the first panel surface 10 and the second panel surface 8 are equipped with friction lug 4, can reduce brake disc
The frictional dissipation of piece, improve the service life of brake disc.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
