The air inlet end of the air guide pipe 1 extends to the front end of the automobile, so that air at the front end of the automobile can enter the air guide pipe 1 through the air inlet 11. The air-out one end fixed connection of guide duct 1 is in wheel casing welt 2, and this end of guide duct 1 runs through wheel casing welt 2 and sets up, makes the air outlet 12 of guide duct 1 just to braking system, and the air current gets into guide duct 1 through air intake 11, flows out behind guide duct 1 through air outlet 12, and direct flow to braking system for the air flow speed of braking system department, makes braking system give off because of the heat that the friction produced fast, cools down braking system.
When the automobile runs, most of air flow is blocked by the front end of the automobile to form automobile wind resistance in the running process, wherein a small part of air flow enters the air guide pipe 1 from the air inlet 11 of the air guide pipe 1, then passes through the wheel cover lining plate 2 and flows out to the braking system from the air outlet 12 to take away heat generated by the braking friction of the braking system, and the braking system is cooled. Moreover, the small part of air flow flows out through the air guide pipe 1, so that the wind resistance of the automobile in the running process is reduced.
In the air guiding structure of the braking system in the above embodiment, one end of the air guiding pipe 1 extends to the front end of the automobile, and the other end extends to the wheel casing lining plate 2 and penetrates through the wheel casing lining plate 2, so that the air outlet 12 of the air guiding pipe 1 is arranged opposite to the braking system. When the automobile runs, part of air flow enters the air guide pipe 1 from the air inlet 11 of the air guide pipe 1 and then flows to the braking system, so that on one hand, the air flow at the braking system can be accelerated, the air flow can be rapidly cooled, on the other hand, the windward area at the front end of the automobile can be reduced, and the wind resistance of the whole automobile can be reduced.
