The present invention relates to a disc-shaped brake disc for automobiles that generates a braking force by squeezing the outer surface by the caliper (C) while rotating combined with the drive shaft of the hub (H) together with the wheel (W), the structure of the lightweight disc for automobiles On the tube.

The housing 10 according to the present invention includes a fastening hole 11 for inducing the wheel W and the hub H to be integrally fastened, and the fastening hole 11 is provided with one or more radially. The housing 10 is made of a material of aluminum alloy having a light weight and excellent heat dissipation. The housing 10 has a bearing on one surface or an inner circumferential surface thereof, and a hub H which is connected to a driving shaft and guides rotation thereof. A wheel W having a tire is mounted on one surface of the hub H.

At this time, the hub H is generally fastened to the inner circumferential surface of the housing 10 together with the bearing as a hub nut (not shown) as fastening spirals are provided on the drive shaft, and the wheel W is radially formed on the housing 10. It is fastened integrally from the fastening hole 11 provided with one or more. That is, the wheel bolt (not shown) is inserted into the interference fit from the rear of the housing 11 to protrude forward to induce the wheel (W) to be fastened. Therefore, while the housing 10 is rotatable about the drive shaft through the hub (H) serves to engage with the wheel (W) having a tire. In addition, at least one fastening hole 12 is radially provided at a predetermined position so as to be integrally fastened with the disk 20 to be described later.

In addition, the disk 20 according to the present invention is provided with a coupling hole 21 for inducing to be integrally coupled with the housing 10, the coupling hole 21 is provided with one or more radially. The disk 20 is formed of a cast iron material of appropriate strength and relatively low material cost, the disk 20 is integrally coupled to one surface of the housing 10 is coupled. That is, one or more coupling holes 21 corresponding to the fastening holes 12 of the housing 10 are provided radially in the disk 20.

Therefore, the disk 20 of the present invention rotates in the same manner as the housing 10 as the coupling hole 21 and the fastening hole 12 of the housing 10 are coupled to each other through a bolt B or a pin (not shown). Done. The outer surface of the disk 20 is inserted on the caliper (C) having a cylinder and a pad, the cylinder is operated according to the driver's operation and the pad is pressed to generate a friction force on the outer surface of the disk 20. That is, it plays a role of stopping while exchanging the kinetic energy of the rotating disk 20 with thermal energy through the friction force.

In addition, the power supply means 30 according to the present invention is provided with a heat dissipation port 31 or a heat dissipation groove 32 to enhance the braking force generated in the outer surface portion of the disk 20. The boosting means 30 serves to enhance the braking force by releasing heat generated by the friction force by the pad and the disk 20 mounted on the caliper C. That is, the disc 20 generates heat of at least 400 ° C. and at most 800 ° C. at the time of braking, and when such heat is left without being instantaneously released to the outside, the friction force decreases to cause fader phenomenon.

On the other hand, the fader phenomenon is a pad provided in the caliper is a form that combines dozens of metal and non-metal particles and fibers with a resin (resin), and also contains some moisture and gas during the bonding solidification process, the friction material and the disk using excessive brake When the surface temperature of 20 is excessively increased, the resin, which is a solid material, forms a gas while oxidizing at a high temperature, and some moisture or gas contained in the friction material is also released to the outside, so that a thin gas layer is provided between the pad friction material and the disk 20. Will form. This means that the gas layer drops the friction coefficient of the friction material so that even if the brake pedal is pressed hard, the disc and the pad will slip and will not brake.

And when this heat is transferred to move to the caliper (C) it causes a vapor lock phenomenon that generates bubbles by breaking the oil present in the cylinder, causing a problem of sharply lowering or losing the braking force. In addition, as a result of the deformation of the disk 20 due to the heat (Judder) occurs, it causes noise as well as damage to other devices. Therefore, the power supply means 30 is for suppressing these problems. A circular heat dissipation hole 31 or a diagonal heat dissipation groove 32 is provided on the outer surface of the disc 20 to instantly generate heat generated by friction. It releases and enhances braking power. That is, the dust and gas layers due to the wear of the pads are smoothly discharged by the circular heat dissipation holes 31 or the diagonal heat dissipation grooves 32 of the disk 20 to prevent slippage, and the braking distance is significantly shortened. It can be applied to hybrid vehicles in line with the green business.

At this time, the heat dissipation hole 31 according to the present invention is formed by arranging the adjacent outer surface portion of the disk 20 so as not to be adjacent to each other, the diameter (Ø) is 5 ~ 7mm while the number is 7.2% of the total surface area It is characterized by forming within ~ 8.8%. The heat dissipation hole 31 is a circular hole having a diameter (Ø) of 5 to 7 mm and is arranged not to be adjacent to each other at a predetermined interval on the outer surface of the disk 20. That is, the heat dissipation holes 31 are arranged at regular intervals in diameter on the outer surface portion with respect to the center of the disk 20. Here, the diameter means the distance between the center of the disk 20 and the center of the heat dissipation port 31 formed on the outer surface portion, the diameter is formed on the outer surface portion at regular intervals.

That is, as shown in Table 1, the heat dissipation port 31 and the heat dissipation port 31 should be formed so as not to be adjacent to each other so that the temperature of the outer surface of the disk 20 is evenly distributed. That is, the diameter of the center of the disk 20 and the center of the heat dissipation hole 31 is 160mm, and if there is one track perforated in a circular pattern of about 10 points with respect to the center of the disk 20, the center of the disk 20 and 2 tracks, 3 tracks, 4 tracks, etc., formed at a distance of 170 mm from the center of the heat dissipation hole 31, that is, 1 mm to 10 mm apart. It consists of seven tracks, which are formed by rotating the angle of the heat dissipation hole 31 formed between these tracks by 12 ° to 14 ° so that they are not adjacent to each other. Therefore, the heat generated by the friction may be evenly distributed while minimizing the crack of the disk 20 due to the heat dissipation 31 to prevent deformation.

At this time, the diameter of the heat dissipation port 31 is 5 ~ 7mm, the size is small, the heat dissipation is inferior, if too large, the effect of reducing the weight, but the noise occurs and the strength is lowered. That is, the diameter of the heat dissipation port 31 will be most preferably formed to a size of 6mm. In addition, the heat dissipation port 31 is preferably formed within 7.2% to 8.8% of the surface area of the entire outer surface of the disk 20, considering that the area of the outer edge of the disk 20 according to each vehicle is different from each other. It is formed as the increase and decrease of the number of 31).

4 is a perspective view showing a disk according to an embodiment of the present invention.

4 is an embodiment of the present invention, the heat dissipation groove 32 is formed by radially arranged at intervals of 60 ~ 80mm on the outer surface portion of the disk 20, while having a width of 3mm, the slope is straight to 55 ° Or it is characterized by forming in an arc. The heat dissipation groove 32 has a width of 3mm and its cross-sectional shape is variously formed in a triangular or square and circular shape. The heat dissipation groove 32 is formed on the outer surface of the disk 20 in a straight line or an arc, but the disk ( All of the outer peripheral surface of 20) may be connected or formed only inside the outer surface portion. The heat dissipation grooves 32 are arranged radially in a circular pattern so as to have a predetermined area on the outer surface with respect to the center of the disk 20.

As shown in Table 2, the heat dissipation grooves 32 and the heat dissipation grooves 32 are preferably formed at intervals of 60 to 80 mm. If the gap with the heat dissipation groove 32 is formed narrow, the pad is quickly consumed, the noise is increased, and if the gap is formed wide, the braking force falls. At this time, the heat dissipation groove 32 is formed in the form of an oblique line so as to have a slope of 55 ° relative to its end. This is to release the gas layer and the dust generated by the friction by the pad to the outside quickly through the heat dissipation groove 32 as the optimum inclination according to the high-speed rotation direction of the disk 20.

5 is a perspective view showing a disk according to a modification of the present invention.

5 is a modified example of the present invention, the heat dissipation port 31 and the heat dissipation groove 32 may be formed on the outer surface portion of the disk 20 at the same time. That is, due to the heat dissipation hole 31, the heat generated by the heat dissipation portion of the disk 20 is evenly distributed and discharged to the outside, and the dust generated by the friction between the pad and the disc 20 due to the heat dissipation groove 32. It is possible to have both discharge and discharge at the same time to quickly discharge the gas layer to the outside. Therefore, when the heat dissipation port 31 and the heat dissipation groove 32 are used at the same time, the braking force is significantly increased while the material cost is reduced, and thus it is easy to adopt to the automakers, thereby allowing consumers to access more easily.

As described above, the disk of the present invention is formed of a dual structure consisting of a disk made of cast iron having a low raw material cost and a housing made of aluminum alloy having a light weight and excellent heat dissipation. It saves time and time, and it has excellent heat dissipation through powering means, so when dust and gas layer are smoothly discharged due to pad wear during braking, it prevents slippage and significantly reduces braking distance. This is possible.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
