Abstract
The utility model discloses a brake disc for a light commercial vehicle, which comprises a front brake disc and a rear brake disc which is involutory with the front brake disc; the braking front disc and the braking rear disc are connected into a whole through a plurality of bosses; the braking front disc is provided with a front through hole between two adjacent bosses, and the braking rear disc is provided with a rear through hole between two adjacent bosses. The front brake disc and the rear brake disc are connected through the bosses, so that the integral mechanical structure of the brake disc can be ensured, the weight of the brake disc can be reduced, in addition, the front brake disc and the rear brake disc are respectively provided with a front through hole and a rear through hole, the light weight of the brake disc is further realized, and the energy conservation and emission reduction of the whole vehicle are realized; a plurality of front through holes and a plurality of rear through holes are respectively formed in the front brake disc and the rear brake disc, so that the ventilation and heat dissipation performance of the brake disc is good, and the brake performance decline caused by overhigh temperature of the brake during long-term multiple braking is prevented.
Description
Technical field
The utility model belongs to brake technical field, and in particular to a kind of light commercial vehicle brake disc.
Background technology
Disk brake is substantially improved with respect to drum brake on thermal stability, water resistant degenerative etc., native land man
Regulation GB7258 requires the breast board car of the front-wheel of other cars of special school bus, hazardous materials transportation vehicle and vehicle commander more than 9m, three axis
Disk brake should be equipped with all wheels of storehouse grating semitrailer.And various light commercial vehicle vehicle factors are more steady to pursue
Fixed reliably braking ability also adds disk brake successively for non-special vehicle, and disk brake will welcome hair at full speed
Exhibition.And or brake disc is solid disk or is that two disks are connected by longitudinal rib at present, the brake disc that longitudinal rib is connected
Although having a very big promotion with respect to drum brake character of heat-fading and water fade, but still the space that is greatly improved.
Invention content
For the purpose of this utility model aiming at the deficiency of above-mentioned technology, providing a kind of can promote disk brake thermostabilization
Property and water resistant decline sexuality light commercial vehicle brake disc, while can also loss of weight realize vehicle lightweight.
To achieve the above object, the light commercial vehicle brake disc designed by the utility model, including braking shroud and with
The braking hub disk of the braking shroud pairing；It connects to be formed by several boss between the braking shroud and the braking hub disk
Whole, one end of the boss is fixed on the braking shroud, and the other end of the boss is fixed on the braking hub disk；
Front through hole is provided on the braking shroud and between two adjacent boss, it is described to brake on hub disk and positioned at two
Rear through-hole is provided between the adjacent boss.
Further, several boss are divided into several circle boss units, often enclose the equal edge of boss in the boss unit
Even circumferential is distributed.
Further, the boss in boss unit described in every two adjacent rings is in staggered distribution.
Further, it is provided between two adjacent lands on the braking shroud and positioned at often enclosing in the boss unit
Front through hole, it is described to brake on hub disk and be provided with rear through-hole between two adjacent lands positioned at often enclosing in the boss unit.
Compared with prior art, the utility model has the following advantages：
1st, braking shroud is connected with braking hub disk by several boss, not only can guarantee the mechanical structure of brake disc entirety, but also
The weight of brake disc can be mitigated, in addition, having front through hole and rear through-hole on braking shroud and braking hub disk, further realized
The lightweight of brake disc, so as to fulfill the energy-saving and emission-reduction of vehicle；
2nd, it brakes and has several front through hole and several rear through-holes on shroud and braking hub disk so that brake disc
Ventilation and heat performance is good, and brake temperature is excessively high when preventing from repeatedly braking for a long time causes braking ability to fail；
3rd, front through hole and rear through-hole are respectively positioned at the gap among two boss so that aproll performance after brake disc is paddled
It is good；Finally, the dust being attached to during friction disc wear when front through hole and rear through-hole can effectively remove braking on rubbing surface, prevents out
Now because dust causes brake force to cross glitch.
Description of the drawings
Fig. 1 is the braking shroud structure diagram of the utility model light commercial vehicle brake disc；
Fig. 2 is the braking hub disk structure diagram of the utility model light commercial vehicle brake disc；
Fig. 3 is the structure diagram of the utility model light commercial vehicle brake disc.
Each part numbers are as follows in figure：
Brake shroud 1, front through hole 2, braking hub disk 3, boss unit 4, boss 5, rear through-hole 6.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Light commercial vehicle brake disc as shown in Figure 1, Figure 2 and Figure 3, including braking shroud 1 and with braking 1 pairing of shroud
Braking hub disk 3；The key point of the present embodiment is：It brakes and connects shape by several boss 5 between shroud 1 and braking hub disk 3
Integral, i.e. one end of boss 5 is fixed on braking shroud 1, and the other end of boss 5 is fixed on braking hub disk 3.Several boss
5 are divided into several circle boss units 4, and the radius of outmost turns (i.e. first lap) boss unit 4 is more than the half of the second circle boss unit 4
Diameter, the radius of the second circle boss unit 4 is more than the radius of third circle boss unit 4, until the radius of the (n-1)th circle boss unit 4
More than the radius of innermost circle (the i.e. n-th circle) boss unit 4, the boss 5 often enclosed in boss unit 4 is circumferentially uniformly distributed；And
And be in staggered distribution per the boss 5 in two adjacent rings boss unit 4, i.e., 5 face of boss in one circle boss unit 4 is adjacent another
At gap in one circle boss unit 4 between two boss 5, that is, boss 5 in two adjacent rings boss unit 4 not face cloth
It puts.
In addition, front through hole 2 is provided on braking shroud 1 and between two adjacent lands 5 in often circle boss unit 4,
Rear through-hole 6 is provided on braking hub disk 3 and between two adjacent lands 5 in often circle boss unit 4.
Braking shroud 1 and braking hub disk 3 are connected by several boss 5, not only can guarantee the mechanical structure of brake disc entirety, but also
The weight of brake disc can be mitigated, in addition, having front through hole 2 and rear through-hole 6 on braking shroud 1 and braking hub disk 3, further
The lightweight of brake disc is realized, so as to fulfill the energy-saving and emission-reduction of vehicle；Due to being had on braking shroud 1 and braking hub disk 3
Several front through hole 2 and several rear through-holes 6 so that the ventilation and heat performance of brake disc is good, prevents long-term repeatedly braking when system
Dynamic device temperature is excessively high to cause braking ability to fail；Meanwhile front through hole 2 and rear through-hole 6 are respectively positioned on the gap among two boss 5
Place so that aproll performance is good after brake disc is paddled；Finally, when front through hole and rear through-hole can effectively remove braking during friction disc wear
The dust being attached on rubbing surface is prevented because dust causes brake force to cross glitch.
