Description

Automotive brake cooling unit {Cooling unit for brake system}

The present invention relates to a brake cooling unit for a vehicle, and more specifically, to a brake cooling unit for a vehicle that can efficiently cool the brakes by forcing air to be supplied to the caliper while rotating in conjunction with the wheels when the vehicle is driven.

The disc of the caliper brake system, which is usually used on the front or rear wheels, forms a disc, a braking disc with a certain thickness, and is connected to the drive shaft.

In addition, the driving speed of a running car can be lowered as the brake disc and brake pad generate friction and generate braking force.

As described above, when driving in harsh environments, driving for long periods of time, or going downhill for long distances, the disc brake disc does not function properly due to overheating due to frequent braking, causing a decrease in braking ability.

In addition, if the brake disc continues to be in contact with the brake pad while it is overheated due to frequent brake operation as described above, more severe wear occurs than usual, and due to the nature of the metal material, cracks may form on the surface or inside of the brake disc in an overheated state. In severe cases, this can cause damage to the brake disc.

Accordingly, in recent years, there has been a need for the development of a technology that cools the brake system by forcing air to be supplied to the brake system while the rotation of the wheel rotates during the driving process.

The configuration of the vehicle brake cooling unit according to the present invention will first be described.

1 is a perspective view showing the configuration of a brake cooling unit for a vehicle according to the present invention.

Referring to Figure 1, the vehicle brake cooling unit according to the present invention is composed of a unit body 100, blades 200, and hub ring 300.

The unit body 100 and blades 200 will be described.

Figure 2 is a perspective view showing the unit body according to the present invention. Figure 3 is a bottom perspective view showing the unit body according to the present invention. Figure 4 is a plan view showing the unit body according to the present invention.

Referring to Figures 2 to 4, the unit body 100 according to the present invention is formed in a disk shape. The unit body 100 may have a thickness of 9 to 12 mm. The thickness can be manufactured to various thicknesses when manufacturing the unit.

The unit body 100 is made of metal or reinforced plastic having a certain level of rigidity.

The blades 200 are formed on the outer periphery of the unit body 100. The blades 200 are formed to protrude outward. The blades 200 are formed integrally with the unit body 100.

Each of the blades 200 is formed in the same shape.

Each of the blades 200 protrudes from one side of the unit body 100 in a plate shape to form an oblique incline along the other side.

Figure 5 is a perspective view showing a blade according to the present invention. Figure 6 is a bottom perspective view showing the blade according to the present invention.

Referring to Figures 5 and 6, the blade 200 according to the present invention is a first fixing member 210, a second fixing member 220, and between the first and second fixing members 210 and 220. It is formed with a blade body 230.

The first fixing member 210 extends from the outer periphery of the unit body 100 to the outside along the first surface.

The second fixing member 220 extends from the outer periphery of the unit body 100 to the outside along the second surface.

Here, the first and second fixing members 210 and 220 are formed in staggered positions at regular intervals on the outer periphery of the unit body 100.

One end of the blade body 230 is connected to the first fixing member 210, and the other end is connected to the second fixing member 220.

Accordingly, the blade 200 according to the present invention may be formed to protrude from the outer periphery of the unit body 100 at an oblique inclination along the circumferential direction.

The blades 200 configured as above are formed to protrude at intervals along the outer circumference of the unit body 100.

Therefore, when the unit body 100 is rotated, the blades 200 can force air to be supplied to the caliper, which will be described later, along the rotation direction.

Meanwhile, referring to FIGS. 1 to 4, the unit body 100 according to the present invention has first bolt fastening holes 110 formed in a long hole shape along the centripetal direction in the center of the unit body 100, and are connected to each other. formed in different locations.

Additionally, one or more second bolt fastening holes 120 formed by connecting one or more long holes may be formed in the unit body 100.

According to this configuration, wheel fastening bolts provided in any vehicle may be disposed through fastening holes whose positions among the first bolt fastening holes 110 and the second bolt fastening holes 120 are aligned.

Furthermore, because the first and second bolt fastening holes 110 and 120 are formed in a long hole shape, it can be easy to align the rotation center of the unit body 100 with the center of the hub of the vehicle.

In addition, it is better to further form cut holes 130 in multiple locations of the unit body 100 to lower the weight of the unit itself 100 below a certain level or to improve heat dissipation. The shape of the cut holes 130 may be formed to gradually widen from the center of the unit body 100 along the outer edge.

Figure 7 is a perspective view showing the hub ring according to the present invention. Figure 8 is a bottom perspective view showing the have ring according to the present invention. Figure 9 is a partially cut away perspective view showing a coupling hole formed in the unit body according to the present invention. Figure 10 is a cross-sectional view showing the hub ring according to the present invention coupled to the coupling hole.

Referring to Figures 7 and 8, the hub ring 300 according to the present invention may be configured to be detachably coupled to the coupling hole 140 formed at the center of the unit body 100. Of course, the hub ring 300 may be formed integrally with the center of the unit body 100. In the following, the former case will be explained as a representative example.

The hub ring 300 according to the present invention has a first outer diameter along the outer side, an outer body 310 forming a step, and a second outer diameter formed on the outer body 310 and smaller than the first outer diameter. It has an inner body 320 that is formed, has steps, and has a central hole.

Here, an inclined member 330 is protruding from the lower outer periphery of the outer body 310.

Additionally, the first outer diameter may be formed to be substantially the same as the inner circumference of the coupling hole 140 of the unit body 100 described above.

Meanwhile, referring to FIG. 9, inclined surfaces 141 are formed at both ends of the inner circumference of the circular coupling hole 140 formed at the center of the unit body 100 according to the present invention.

Here, the inclination of each of the inclined surfaces 141 preferably forms the same inclination angle as the inclination formed in the inclination member 400.

In addition, the thickness of the outer body 310 of the hub ring 300 is preferably formed to be the same as the thickness of the unit body 100.

Through this configuration, the state in which the hub ring 300 is coupled to the unit body 100 will be explained.

Referring to Figures 1 and 10, Figure 10 shows a cross-section along line A-A in Figure 1.

The hub ring 300 according to the present invention is inserted into the coupling hole 140 formed at the center of the unit body 100.

Here, since the first outer diameter of the outer body 310 of the hub ring 300 is substantially the same as the inner diameter of the coupling hole 140, they are in close contact with each other.

At the same time, the inclined surface of the inclined member 330 formed on the outer body 310 is in inclined contact with the inclined surface 141 formed at either end of the inner circumference of the coupling hole 140 and is in close contact.

In this state, a cooling unit according to the present invention, such as a spacer, can be placed between the wheel and the hub installed on the rotation axis line of the rotor.

Here, since inclined surfaces 141 with the same inclination are formed on both ends of the inner circumference of the coupling hole 140 of the unit body 100 according to the present invention, the hub ring 300 having the inclined member 330 is connected to the coupling hole 140. ), the direction of coupling between them can be freely selected.

And the cooling unit can act as a spacer. And a caliper having a pair of pads is disposed on the outer portion of the rotor. The pair of pads presses both sides of the rotor to generate friction and performs a braking function. Accordingly, a certain amount of heat is generated due to friction in the area where the braking action occurs.

Meanwhile, protruding blades 200 are formed on the outer periphery of the unit body 100 according to the present invention as described above. Since the unit body 100 is linked to rotor rotation, the blades 200 can rotate to force air to be supplied to the caliper. Accordingly, since air below a certain temperature is supplied to the part where the braking action is performed, the part can be easily cooled.

Figure 11 is a perspective view showing a cooling unit with blades of different shapes. Figure 12 is an enlarged perspective view showing the blade of Figure 11.

Referring to FIG. 11, each of the blades 600 protrudes from the outer periphery of the unit body 500 in a rib shape along the centripetal direction of the unit body 500.

The width of each of the blades 600 is formed to widen from the outer periphery of the unit body 500 along the centripetal direction of the unit body 500.

Referring to FIG. 12, each of the blades 600 includes a first blade member 610 having a first width W1 equal to the width of the unit body 500, and a first blade member 610 at an end of the first blade member 610. It is formed as a second blade member 620 that extends on both sides and has a second width W2 that gradually becomes wider than the width of the unit body 500.

Here, as the cooling unit according to the present invention is disposed between the rotor and the wheel, there is a gap between them.

The second width W2 of the second blade member 620 is preferably determined within the gap.

Through this, when the unit body 500 is rotated according to the rotation of the rotor, the air is kept constant by the second blade members 620 having a second width W2 wider than the width of the unit body 500 as described above. Cooling can be made more efficient by forcibly supplying heat to the caliper side where heat is generated at a higher flow rate.

Additionally, in the present invention, in order to increase the supply flow rate of air, the second blade member 620 of each of the blades 600 may be bent at a predetermined angle at the end of the first blade member 610.

According to the above-described structure and operation, the present invention forms blades on the outer circumference of the unit body, which is a spacer between the rotor and wheel of the vehicle, and forces air to be supplied to the caliper by the blades when the wheel rotates, thereby efficiently operating the brakes. It can be cooled.

In addition, the present invention has the effect of enabling application to different types of vehicles by allowing wheel bearings with various hollow sizes to be selectively installed in the center of the unit body.

In addition, the present invention forms long holes and multiple long holes into one hole along the direction radiating from the center of the unit body by bolt fastening holes in the unit body, so that fastening bolts with various fastening positions can penetrate, and through this, can be applied to different types. It has the effect of allowing you to do so.

Each of the blades 800 includes a first blade body 810 whose width is gradually increased from the first position to the second position on the outer periphery of the unit body 700, and the first blade member 810. It is formed as a second blade body 820 that is bent around the circumference and whose height is gradually lowered from the second position to the first position.

Referring to FIG. 15, the circumference of the first blade 810 forms a certain curvature. Additionally, the circumference of the second blade 820 also forms a curvature. In addition, it is recommended that the connection portion between the first and second blades 810 and 820 be curvatured. Through this, when the unit body 700 is rotated by the rotation of the rotor, air resistance at the corners and circumferences is reduced to a certain level or less to facilitate rotation, and air is forcibly supplied by the area of the blade 800.

Additionally, the first blade body 810 follows the same plane as the unit body 700, and the second blade body 820 is bent to be perpendicular to the first blade body 810.

In addition, first bolt fastening holes 710 are formed at multiple locations in the unit body 700 along the circumferential direction based on the center of the unit body 700. The first bolt fastening holes 710 are formed in a long hole shape to allow the fastening bolts protruding from hubs of different specifications to change positions and penetrate through them. Additionally, heat dissipation holes 720, as in other examples above, are formed at multiple locations of the unit body 700.

The hub ring 900 shown in FIG. 16, which has an inclined member 910 in oblique contact with the inclined surface 731 on the outer periphery, is selectively coupled to the coupling hole 730.

An inclined member 910 that protrudes outward and has a predetermined inclination along the outer side is formed integrally around one side of the lower ring 900.

Here, the inclination of the inclined member 910 is preferably the same as the inclined surface 731 formed at one end of the inner circumference of the coupling hole 730.

When the hub ring 900 is coupled to the coupling hole 731, the inclined member 910 formed on the hub ring 900 makes inclined contact with the inclined surface 731 formed on the inner periphery of the coupling hole 730, The hub ring 900 may be detachably installed in the coupling hole 730 of the unit body 700.

In addition, the hub ring 900 is formed with a central hole 920 through which the central member provided in the hub, which is the counterpart, passes through. The central member of the hub may have different outer diameters in different types of vehicles.

Accordingly, in the present invention, a hub ring with a central hole 920 that matches the outer diameter size of the central member of the vehicle may be selected and selectively installed in the coupling hole 730 of the unit body 700.
