The invention has the beneficial effects that:

1. Through setting up the heat dissipation through-hole at the brake disc, can destroy the air cushion membrane that lasts brake in-process brake disc surface and produce, further increase the mobility of air, strengthen the radiating effect, avoid producing high temperature decline, also make the heat be unlikely to too much transmit the tire through the wheel rim simultaneously on, reduce the risk of high temperature tire burst.

2. Through set up the arc wall on the brake disc, can let the dust that brake block and brake disc friction produced through the arc wall as early as possible dispersion to the air to avoid producing rolling friction because of between brake block and the dust, improve the frictional force between brake disc and the brake block.

3. Through setting up the supporting component in that the brake disc is inside, when rainy day or through water hole, water can pass in the passageway that forms between the supporting component, and the lubrication phenomenon that can effectively avoid the water film to produce and the brake effect that leads to the fact weakens, and simultaneously, the supporting component can undertake more pressure, improves the joint strength between the upper and lower brake disc, avoids because the increase of heat dissipation through-hole and the brake disc intensity that leads to the fact is not enough.

4.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-3, a quick heat dissipation motor vehicle brake disc comprises a mounting disc 3, an upper brake disc 5 and a lower brake disc 7 are mounted on the outer side wall of the mounting disc 3 through bolts, a plurality of supporting assemblies 6 are symmetrically arranged between the upper brake disc 5 and the lower brake disc 7, each supporting assembly 6 comprises a water drop-shaped supporting column 601 and four triangular supporting columns 602, a plurality of groups of heat dissipation through holes 4 are symmetrically formed in the disc bodies of the upper brake disc 5 and the lower brake disc 7, and a plurality of arc-shaped grooves 1 are symmetrically formed in the upper surface of the upper brake disc 5, so that dust generated by friction between a brake pad and the brake disc can be dispersed into air through the arc-shaped grooves 1 as soon as possible, rolling friction between the brake pad and the dust is avoided, and friction force between the brake disc and the brake pad is improved.

In the invention, a plurality of mounting holes 2 are symmetrically formed in the mounting plate 3 and used for positioning and mounting the mounting plate 3.
