Brake discs are heated by friction with the brake pads, and the brake discs are exposed to the outside for heat release by friction.

The braking force of the vehicle is closely related to the cooling of the frictional heat generated in the brake disc. Frequent braking during sudden braking or long downhill causes fade or vapor lock due to overheating of the brake disc. There is a problem that the braking force drops rapidly.

Fig.

1, a brake disk air cooling apparatus 1 according to an embodiment of the present invention rapidly discharges frictional heat generated from a brake disk into the atmosphere, rotates together with the wheel when the vehicle is traveling, And the flow of air is increased at a portion where frictional heat is generated in the brake disk 110, and includes a coupling plate 10 and a radiating fin 20. [

1 to 3, the coupling plate 10 is formed of a circular metal plate and is interposed between the tire wheel 200 and the disk hub 120. The coupling plate 10 is formed with a plurality of through holes 10h through which the bolts B projecting from the disk hub 120 pass.

The tire wheel 200 is coupled to a disk hub 120 connected to an axle. The disk hub 120 is provided with a flat surface with a plurality of bolts B projecting around the center of rotation. The tire wheel 200 is provided with a hole into which the bolt B is inserted, and is assembled with a nut. The coupling structure of the tire wheel 200 and the brake disc 110 is a well-known technology in the automobile industry, and thus a detailed description thereof will be omitted.

1, in the brake disk air cooling apparatus 1 of the present invention, the coupling plate 10 is formed of a relatively thin metal plate and interposed between the tire wheel 200 and the disk hub 120, Since the plate 10 has a flat surface on both sides, the disc hub 120 and the tire wheel 200 maintain a rigid coupling structure even if they are interposed between the tire wheel 200 and the disc hub 120.

The disc brake 100 is composed of a caliper 130 for pressing a brake pad (not shown) and a brake disc 110 for pressing on the brake pad.

The piston (not shown) that presses the pad moves by hydraulic pressure, and the brake pad mounted on the caliper 130 presses the brake disc 110 to generate friction as noise, thereby forming a braking force. Heat is generated in the brake disk 110 due to friction with the brake pads, and the brake disk 110 is exposed to the outside for releasing heat due to friction.

The braking force of the automobile is closely related to the cooling of the frictional heat generated in the brake disc 110. Frequent braking during sudden braking or long downhill may cause a fade phenomenon due to overheating of the brake disc 110, vapor lock phenomenon occurs and the braking force drops rapidly.

The brake disk air cooling apparatus 1 of the present invention expands the heat dissipation fins 20 along the periphery of the coupling plate 10 to quickly release heat of the brake disk 110. [

The cooling of the brake disk 110 is caused by an increase in heat transfer area by the radiating fin 20 and induction of air flow.

First, the increase in the heat transfer area will be described below.

Heat generated in the brake disk 110 in the vehicle is transferred to the surrounding air through the surfaces of the brake disk 110 and the disk hub 120 to be cooled. The main component of the brake disc is cast iron, which has a low thermal conductivity and thus has a disadvantage that the heat transfer rate to the air is slow.

Since the coupling plate 10 is formed of a material having a high thermal conductivity and is in close contact with the disk hub 120 in the present invention, the heat energy transferred from the brake disk 110 to the disk hub 120 is transmitted to the heat dissipation fin 10, The heat dissipation fins 20 raise the cooling area of the brake disk 110 by raising the heat transfer area where the coupling plate 10 is in contact with the air.

Since the coupling plate 10 and the radiating fin 20 are rotated together with the axle during vehicle travel, a rapid air flow is formed around the radiating fin 20, and the air cooling rate .

2 and 3, in the brake disk air cooling apparatus 1 of the present invention, the radiating fin 20 comprises an extension blade 21 and a guide blade 22.

The extension wing 21 is a radially extending portion of the engagement plate 10, preferably projecting in a plane parallel to the extension wing 21. The extension wings 21 are formed at a plurality of intervals along the circumference of the coupling plate 10 at regular intervals.

The guide vane 22 is configured to press the air around the disc hub 120 toward the brake disc 110 and extend from the side of the extension vane 21 toward the brake disc 110.

The coupling plate 10 and the radiating fin 20 can be manufactured by a method of bending the guide vane 22 after cutting the metal plate with a laser cutter or by simply machining it through a CNC machine of aluminum plate.

The above-mentioned increased heat transfer area means the surface area of the extension wing 21 and the guide wing 22.

More specifically, the extending blades 21 extend in the radial direction of the engaging plate 10 to increase the heat transfer area, and the guide blades 22 are disposed on the front side of the extending blades 21 with respect to the rotating direction of the axle To the brake disk 110 to induce the flow of air by the pressurization with the increase of the heat transfer area.

The induction of airflow by the radiating fin 20 will be described below.

2 and 3, the guide vane 22 forms a surface having a right angle or an oblique angle with respect to the rotation direction of the axle so as to press the air around the disk hub 120 in the rotation direction of the axle , The pressurization by the guide vane 22 increases the air flow around the disk hub 120.

The air pressurized in the rotational direction of the axle around the disk hub 120 forms a flow toward the edge of the brake disk 110 by the centrifugal force and by increasing the amount of air in contact with the surface of the brake disk 110 The amount of heat transferred from the brake disc 110 to the air increases, and the cooling speed of the brake disc 110 increases.

The caliper 130 is a vise-like portion having a piston for supporting the brake pads on both sides or one side of the brake disc 110. The caliper 130 surrounds one side of the brake disc 110. The caliper 130 is installed on a suspension, Respectively.

2 and 3, as the caliper 130 wraps around one edge of the brake disk 110, a narrow path through which pressurized air passes is formed between the caliper 130 and the disk hub 120 And the guide vane 22 in the brake disc air cooling apparatus 1 of the present invention is formed so as to extend from the side of the extended vane 21 to pass through between the caliper 130 and the disc hub 120 during rotation of the axle, . It is preferable that the extension wings 21 also extend from the periphery of the engagement plate 10 to the extent that they do not collide with the caliper 130.

The flow of air pressurized by the guide vane 22 is transmitted to the caliper 130 and the disk hub 120 as the guide vane 22 passes the narrow path between the caliper 130 and the disk hub 120 during axle rotation. And the speed increased air is rapidly introduced into the surface of the brake disk 110 rubbing against the pad and the surface of the brake disk 110 immediately after rubbing against the pad.

The prior arts disclosed in Japanese Patent Application Laid-Open Nos. 2002-0047469 and 1998-051577 have problems in that the large wings always generate wind during rotation of the axle, resulting in deterioration of fuel efficiency due to air resistance of the large wings in the long term And therefore the cooling structure of the brake disk disclosed in the automobile industry in the open patent publications 2002-0047469 and 1998-051577 is not applied.

The brake disk air cooling apparatus 1 of the present invention is configured such that the guide vanes 22 are formed to be small enough to pass narrow paths between the caliper 130 and the disk hub 120 to lower the air resistance As described above, there is an advantage that the cooling rate of the frictional heat is rather increased by forming a flow of air at a portion where frictional heat is generated immediately after frictional heat is generated in the brake disk 110 as described above.

On the other hand, when friction between the brake pads and the brake disc 110 occurs, the brake pads having a hardness lower than that of the brake discs 110 are worn to form a frictional force. The dust particles due to wear of the brake pads are vaporized by the high- And forms a reaction force to push the brake pads backward, which acts as a factor of lowering the braking force.

The brake disk air cooling apparatus 1 of the present invention is capable of preventing the brake disk 110 and the brake disk 110 from being damaged by forming a rapid air flow to the rubbed portion of the brake disk 110 immediately after the brake disk 110 is rubbed against the pad, It is possible to maximize the braking force of the disc brake 100 by suppressing the gasification of the dust powder generated during the inter-rubbing and quickly discharging the dust powder to the outside.

4 and 5, the brake disk air cooling apparatus 2 according to another embodiment of the present invention includes a guide vane 22 for guiding the guide vane 22 to the extended vane 21 with respect to the direction of rotation of the axle during forward travel of the vehicle, As shown in Fig.

6, the extension wing 21 is interposed between the brake disk 110 and the tire wheel 200 between the caliper 130 and the disk hub 120, and is guided by the rotation direction of the axle The air pressurized by the rotation of the guide vane 22 in front of the vane 22 is limited to flow toward the tire wheel 200 by the vane 21 so that the flow amount toward the brake disc 110 increases.

Therefore, the brake disk air cooling apparatus 2 according to another embodiment of the present invention is configured such that the guide vane 22 is formed to be small enough to pass the narrow path between the caliper 130 and the disk hub 120, The frictional heat is generated in the brake disc 110 immediately after the frictional heat is generated and the most of the pressurized air is caused to flow toward the brake disc 110. As a result, There is an advantage that it can be cooled quickly.

4 and 5, a brake disk air cooling apparatus 2 according to another embodiment of the present invention includes a disk brake 100, a disk hub 120, a disk hub 120, a disk hub 120, The curved surface member 30 forming an arc-shaped curved surface can be engaged.

4 to 6, the curved surface member 30 has a configuration for guiding the flow of the air pressurized by the guide vane 22 toward the brake disk 110 and includes an extension plate 31, A plate 32 and an induction plate 33 as shown in Fig.

The extension plate 31 is configured to extend from the caliper 130 toward the disk hub 120. The extension plate 31 is formed to extend from the caliper 130 toward the disk hub 120 while being coupled to the caliper 130 at one end. Although not shown, one end of the extension plate 31 can be fastened to the caliper 130 by bolts.

The curved plate 32 is configured to form an arc-shaped curved surface between the guide vane 22 and the caliper 130 and extends from the end of the extension plate 31 toward the disc hub 120 toward the brake disc 110 . The extension plate 31 forms an arc-shaped curved surface around the center axis of the disk hub 120 connected to the axle, and is spaced apart from the guide vane 22 by a predetermined distance so as not to collide with the guide vane 22.

As the curved plate 32 extends from the extension plate 31 toward the brake disc 110, a space open toward the brake disc 110 is formed inside the caliper 130, the extension plate 31, .

As described above, the air pressurized in the rotating direction of the axle by the guide plate 33 rotates about the disk hub 120 and flows to the edge of the brake disk 110 by the centrifugal force. 5 and 6, a portion f2 of the air flowing to the edge of the brake disk 110 is guided by the caliper 130, the extension plate (not shown) 31) and into the space inside the curved play.

The guide plate 33 is formed between the curved plate 32 and the caliper 130 so as to guide the flow of air introduced between the curved plate 32 and the caliper 130 toward the brake disk 110. Preferably, the guide plate 33 is formed at the front end of the curved plate 32 with reference to the direction of rotation of the axle during forward travel of the vehicle.

5 and 6, the flow of air (f2) introduced into the inner space of the caliper 130, the extension plate 31 and the curved surface is interrupted by the guide plate 33 so that the brake disk 110 Immediately after the frictional heat is generated in the frictional heat generating portion, the frictional heat is concentratedly flowed to the frictional heat generating portion, thereby accelerating the cooling rate of the frictional heat.

The radiating fin 20 is rotated between the disk hub 120 and the curved surface of the curved member 30 so that the air f1 pressurized by the guide vane 22 rotates The air flow f2 flowing into the caliper 130, the extension plate 31, and the inner space of the curved surface play, by flowing toward the brake disk 110 that has been opened (blocked by the curved plate 21 and the curved plate 32) There is an advantage that the cooling rate of the frictional heat is further accelerated because the frictional heat is intensively flowed to the portion where the frictional heat is generated immediately after the frictional heat is generated in the brake disk 110. [

Referring to FIG. 7, the guide vane 22 may be inclined rearward with respect to the rotational direction of the tire wheel 200 when the vehicle is running forward as the brake disk 110 is approached. In Fig. 7, A indicates the brake disc 110 side, and B indicates the tire wheel 200 side.

When the guide vane 22 is inclined rearward with respect to the rotational direction of the tire wheel 200 when the vehicle is running forward as the guide vane 22 gets close to the brake disc 110, the pressurized air is guided along the inclined surface of the brake disc 110, There is an advantage that it flows more smoothly to the edge of the body.

7, in the brake disk air cooling apparatus 3 according to yet another embodiment of the present invention, the radiating fin 20 is provided with an extended blade (not shown) on the basis of the rotating direction of the tire wheel 200 And a guide vane 23 extending from the front end of the guide groove 21 toward the tire wheel 200.

The air on the side of the tire wheel 200 can be easily guided toward the guide vane 22 along the inclined surface of the guide vane 23 on the basis of the extended vane 21 when the radiating fin 20 further has the inclined guide vane 23 There is an advantage that the cooling rate of the frictional heat is further accelerated by increasing the amount of air that is introduced and pressurized by the guide vane 22. [

The guide vane 22 rotates and presses the air between the caliper 130 and the disk hub 120 toward the brake disk 110 to rotate the brake disk 110 together with the wheel So that the flow of air is increased at the portion where the frictional heat of the brake disc 110 is generated so that the air resistance due to wind formation is lowered to a level not affecting the fuel consumption and the cooling efficiency of the brake disc 110 It is possible to provide a brake disk air cooling apparatus (1, 2, 3) which can be improved.

According to the present invention, the coupling plate 10 having a high thermal conductivity is brought into close contact with the disk hub 120 and the heat dissipation fin 20 is formed along the periphery of the coupling plate 10 to increase the heat transfer area, (1, 2, 3) which is configured to rapidly discharge the frictional heat generated in the combustion chamber (110) to the atmosphere.

The guide vane 22 is rotated while pressing the air between the caliper 130 and the disk hub 120 toward the brake disc 110 to rotate together with the wheel 200 to move the brake disc 110 So that the flow of air is increased at the portion where the frictional heat of the brake disc 110 is generated so that the air resistance due to wind formation is lowered to a level not affecting the fuel consumption and the cooling efficiency of the brake disc 110 It is possible to provide a brake disk air cooling apparatus (1, 2, 3) which can be improved.

In addition, a rapid air flow is formed in the rubbed portion of the brake disk 110 immediately after the brake disk 110 is rubbed against the pad, so that the gasification of the dust powder generated upon friction between the brake pad and the brake disk 110 (1, 2, 3) which is capable of effectively suppressing the dust particles and discharging the powder dust quickly to the outside.
