Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brake cooling device for an automobile, which cools a disc brake arranged inside the front wheels of an automobile by using traveling wind.

[0002]

2. Description of the Related Art FIGS. 7 to 9 show an example of a conventional vehicle brake cooling device. This cooling device includes an air intake 2 on the front of the front bumper 1 and a front end opening 3a of an air duct 3.
Is positioned, the rear end opening 3b is fixed to the front end of the fender protector 5 of the front wheel 4, and is directed toward the inner side of the brake 6 arranged inside the front wheel 4. 7 is a splash guard and 8 is a drive shaft.

[0003]

[Problems to be solved by the invention] Recently, in the space of the fender protector and the splash guard,
Since various parts such as an intercooler have been installed, the layout of the air duct cannot be freely provided in the above-mentioned prior art, the air resistance increases, and when the wheels tilt inward. However, there is a problem in that the air does not directly contact the brakes and the cooling efficiency decreases (for example, Japanese Utility Model Publication No. 62-42604).

[0004]

DISCLOSURE OF THE INVENTION The present invention aims to solve the above-mentioned problems, and to reduce the number of wheels inside the wheel,
Also takes in the running wind from below along the outside surface of the splash guard that is erected side by side on the front side part.
An air guide having a shape in which a substantially U-shaped peripheral wall portion projecting in the upward direction guides the air flow upward, and an inclined surface surrounded by the peripheral wall portion blows air toward a brake provided on a wheel. It is characterized by being attached.

[0005]

The cooling device takes in air from below by an air guide attached to the outer surface of the splash guard, guides it upward, and blows it toward the brakes provided on the wheels.

[0006]

1 to 3 show a first embodiment of the present invention.
Reference numeral 10 is a front bumper, 11 is an air intake, 12 is a front wheel, 13 is a splash guard standing inside the front wheel 12, 14 is a fender protector, and 15 is a brake.

In the present invention, the air guide 16 is fixed to the outer surface of the splash guard 13, the lower end opening 16a is directed obliquely downward and downward, the middle is curved upward, and the upper end opening 16b is directed toward the brake 15. It has a shape.

Next, the operation will be described. splash
The guard is mounted along at least the front half of the wheel
Therefore, the wind introduced from the front side is between the rotation axis of the wheel
Can be sprayed on the appropriate part (brake rotor) of
Wear. The air guide is narrower on the front side in consideration of the cutting angle.
The wind is designed to pass through a pair of walls standing upright in the width direction of the car body.
Inside When traveling, the rotating wheels have an air flow in the direction of rotation of the wheels.
To occur. The walls block the air flow
Effectively the guided wind is not disturbed by the air flow
Guided by the brakes.

4 to 6 show a second embodiment of the present invention. 10 is a front bumper, 11 is an air intake, 12
Is a front wheel, 13 is a splash guard standing upright inside the front wheel 12, 14 is a fender protector, 15
Is a brake.

In the present invention, the air guide 16 is fixed to the outer surface of the splash guard 13, the lower end opening 16a is directed obliquely downward and downward, the middle is bent upward, and the upper end opening 16b is directed toward the brake 15. It has a shape. An air duct 17 has a front end opening 17a located at the air intake 11, and a rear end opening 17b located near the upper end opening 16b of the air guide 16.

Next, the operation will be described. The traveling wind from below the front bumper 10 is introduced from the lower end opening 16a of the air guide 16 and guided upward, and even when the wheels are tilted inward, the front wheel 12 is always guided from the upper end opening 16b.
It is sprayed toward the brake 15 of the. Further, the traveling wind from the air intake 11 of the front bumper 10 is introduced into the air duct 17 and guided upward, so that the air guide 16
Sent toward the upper end opening 16b of the air guide 16
The brake 15 is cooled by the air from both the air duct 17 and the air duct 17. It is sprayed from the upper end opening 16b toward the brake 15 of the front wheel 12 for cooling.

[0012]

[Effect of the Invention] According to the present invention, this wheel is placed inside the wheel.
Of the splash guard installed so as to be juxtaposed on at least the front side part of the splash guard is guided upward by a substantially U-shaped peripheral wall part that takes in traveling wind from below and projects laterally , Further, since an air guide having a shape that blows air toward a brake provided on the wheel is attached by the inclined surface surrounded by the peripheral wall portion, a space between the splash guard and the wheel is attached. Can be efficiently used, and even when the wheels are tilted inward, the cooling air can always be guided to the vicinity of the brake device for the wheels, and is also disturbed by the air flow due to the rotation of the wheels.
Since it does not occur, the cooling efficiency is improved, and since it constitutes a part of the splash guard, it has an effect that it can be manufactured at low cost.
