As shown in FIG. 1, the brake pad 10 is flat. Lining, that is, the friction material 14 is fixedly attached to the back plate 12, and is incorporated in the caliper of the disc brake.

The brake pad 10 serves as a brake shoe of a drum brake, but its area is much smaller than that of the brake shoe, and conversely, the force for pressing the disk is several times larger. This makes the work worse than the brake shoe, so the life is much shorter than the brake shoe.

The friction material 14 is formed by heating and pressing the powdery friction material composition and fixedly attaching the molded product in the step of finally compressing the molded product to the back plate 12.

3 and 4, when a bundle of copper wires 490 having a thread shape as a predetermined particle size is introduced through the guider 320 (S11 of FIG. 14), the driving motor 330. The rotational force of the upper and lower rollers 380 and 386 are transmitted to the first and second pinion gears 364 and 384 via the first chain 350 and the second chain 370. By rotating, the copper wire 490 is conveyed backward through the two rollers 380 and 386 (S12 of FIG. 14).

5 and 6, the copper wire 490 entered into the housing 481 includes the rotary cutter 442 of the rotary blade 440 installed on the rotary shaft 420, and the fixed cutter ( 446 between the cutters 442 and 446 to make a first cut (S13 in FIG. 14), the cut copper wire 492 is a through hole in the inner surface of the mesh member 450 (see 682 in FIG. 9). While falling through), it is discharged to the copper wire discharge portion 312 through the induction path (481b).

At this time, the particle size of the cut copper wire 492 is used to form the size of the through-holes on the inner surface of the mesh member 450 appropriately to have a range of about 0.2 ~ 0.5㎜.
Thereafter, as shown in FIGS. 7 and 8, the cut copper wire 492 is transported backward by the conveyor belt 530 (S14 of FIG. 14), and the cut copper wire 492 is cut during the transfer process. Ferromagnetic material, such as mixed iron 570, is attached by the magnet 560 to prevent its transfer. The cut copper wire 492 transferred as described above falls inside the housing 620 via the storage container 630 (S15 of FIG. 14).

At this time, since the height from the inlet of the storage container 630 to the copper wire collection and secondary cut portion 600 is only about 40 cm, the cut copper wire 492 having a predetermined size and weight is a storage container ( 630, the copper wire is collected and lowered directly to the secondary cut part 600 without being scattered from the inside.

The cut copper wire 492 falling in this way is as shown in FIGS. 9 to 11, between the rotary cutter 662 of the rotary blade 660 installed on the rotary shaft 650, and the fixed cutter 670. Secondary cutting is performed by the cutters 662 and 670 (S16 of FIG. 14), and the cut copper chip 692 falls through the through hole 682 of the inner surface of the mesh member 680. It is discharged downward through the induction furnace 622.

At this time, the particle size of the copper chip 692 is used to form the size of the through hole 682 of the mesh member 680 appropriately to have a range of about 0.08 ~ 0.36mm.

The copper chip 692 is dropped into the horizontal guideway 702, one end of which is closed, by the blower 708 to the horizontal extension portion 704a, the casing 704, and the vertical guideway 709. 14 is discharged to the outside (S17 of FIG. 14), the discharged copper chip 692 is collected and inspected through a passage (not shown) connected to the vertical induction path 709, and then packaged by particle size or length (Fig. S18 of 14).

Fig. 15 shows that a copper chip 692 having a particle size of 0.08 to 0.36 mm obtained through the apparatus described above is contained in a plastic container.

The copper chip 692 thus obtained is added to the reinforcing material of the above-described brake pad friction material composed of a reinforcing material, a bonding material, a filling material, and a friction adjusting material in a range of 3 to 10% by weight, and the copper chip 692 is described above. As described above, it is preferable to have a particle size of 0.08 to 0.36 mm.

In this case, the reinforcing material may reduce the compounding ratio of asbestos, which is a main component, by the compounding ratio in which the copper chip 692 is blended, or add 3 to 10 wt% copper chip 692 to the reinforcing material. The copper chip 692 increases the contact area between the pad and the disk during friction, thereby increasing slippage and heat transfer effects, thereby reducing wear and increasing heat resistance of the disk.

Table 1 below shows the item-specific characteristics of various fibers for friction materials.

In this case, the mixing ratio of the copper chip in the present invention is limited to 3 to 10% by weight, it is difficult to expect the effect of addition when added less than 3% by weight, the value of the consumer supply is increased due to the cost increase when the addition of more than 10% by weight This is because a thin film formed on the surface of the friction material is excessively formed by the copper chip, so that the braking distance is long when the brake is operated and noise is generated.

In addition, the copper chip is limited to have a particle size of 0.08 to 0.36 mm, when the copper chip has a particle size of less than 0.08 mm, it is close to the powder form, it is difficult to expect the addition effect, in the case of a length exceeding 0.36 mm thermal conductivity Is lowered and noise is generated.

Hereinafter, the friction material for a brake pad of a vehicle containing a copper chip according to the present invention will be described in detail as follows.

[Example]

Steel fiber: 20 ~ 40 wt%, Copper chip: 3 ~ 10 wt%, Heat resistant organic fiber (KEVLAR): 2 ~ 7 wt%, Inorganic type: 2 ~ 7 wt%, Organic type: 1 ~ 5 wt%, Lubricant : 8 ~ 20% by weight, metal: 10 ~ 15% by weight, oxidizing system: 1 ~ 5% by weight, thermosetting resin (phenol resin): 7-12% by weight, and then in a mixer by drying Blended.

At this time, the copper chip was manufactured through the above-described manufacturing process, and after the temporary molding as the 150 ~ 300 ㎏ / ㎝ at room temperature with the blended material, and was thermoformed in a temperature range of 145 ~ 150 ℃.

Thereafter, the heat-formed friction material is heat-treated at a temperature in the range of 190 to 200 ° C., and the heat-treated friction material is cut and cut to a dimension of a product thickness, and the coating, marking, and packaging are used to produce the polished friction material. After the operation, the friction pad was fixedly attached to the back plate through the brake pad manufacturing process as described above to complete the brake pad.

FIG. 16 shows the brake pad 100 in which the copper chip 200 as described above is contained in the friction material 104 and attached to the back plate 102. According to the present invention, the copper chip 200 contained in the friction material 104 of the brake pad 100 forms a thin film on the surface of the friction material 104 even in low heat, so that braking is smoothly performed during operation of the vehicle.

In addition, since the friction material 104 contains a non-ferrous metal copper chip 200, the life of the friction material 104 can be extended during the brake operation. In other words, other metals are not ductile and have low thermal conductivity, which makes it difficult to produce noise and reduce braking distances. However, copper has excellent characteristics in terms of stability, wear resistance, noise resistance, and heat resistance.

In addition, the copper chip 200 protects the disk by forming a thin film on the surface of the friction material 104 during brake operation, thereby extending the life of the disk.
