Description

[0001] CALIBER BRAKE [0002]

The present invention relates to an automotive caliper brake in which an inner pad disposed on the inboard side and an outer pad disposed on the outboard side are formed of different materials from each other with respect to the disk.

Generally, a caliper brake applied to an automobile includes a caliper housing, a disk rotating with the wheel, and a pair of pad plates installed on both sides of the disk.

More specifically, the caliper housing has a structure in which the above-mentioned disk and a pair of pad plates are accommodated in the inside of the caliper housing. In one side of the caliper housing, a piston moving back and forth in contact with the rear surface of the pad plate, And a finger portion is formed on the other side of the cylinder portion, which is connected to the cylinder portion and is in contact with the rear surface of the pad plate disposed on the other side of the disk. At this time, the front surface of each pad plate is provided with a friction pad which is brought into contact with the disk when the vehicle is braked to generate a braking force.

That is, when the driver depresses the brake pedal, the caliper brake generates hydraulic pressure in the master cylinder by the booster, and the hydraulic pressure thus generated is transmitted to the caliper housing and then to the piston disposed inside the cylinder.

Therefore, the piston pushes the pad plate disposed on the cylinder side to the disk side, and the hydraulic pressure remaining in the cylinder portion is transmitted to the opposite fingers connected to the cylinder portion, so that the finger portion moves inward, The pad plate is pushed to the disc side so that the friction pad provided on the front surface of each pad plate presses the disc to brak.

On the other hand, when the driver releases his / her foot from the brake pedal, the piston is restored to its original position, and the friction pad on the cylinder side and the friction pad on the finger rejection side are separated from the disk again to release the braking.

At this time, the friction pads provided on the front surfaces of the pair of pad plates are generally made of a material such as low steel or NAO (Non-Asbestos Organic).

The friction pads made of low-steel material are made of steel fiber and have excellent strength and friction coefficient. The friction pads made of NAO material are made of various fibers such as glass, copper, ceramics and carbon instead of steel fibers. And the braking force and the aggressiveness against the disk are good, and there is a characteristic that noise is little generated during braking.

However, the friction pads made of low-steel materials have a high aggressiveness against the discs, resulting in a large amount of wear on contact with the disc, and the friction pads made of the NAO material have a relatively low mechanical strength.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a friction pad made of a low-steel material and a friction pad made of a NAO material, And to improve the braking performance as well as increase the efficiency by applying the advantages to each material at the same time, and to provide a caliper brake for an automobile.

According to an aspect of the present invention, there is provided an automotive caliper brake comprising a disk, an inner plate disposed on the inboard side with respect to the disk, a braking member mounted on the front surface of the inner plate, An outer plate disposed on an outboard side symmetrical to the inner plate, an outer pad attached to a front surface of the outer plate and closely contacting the disk with the inner pad to generate a braking force, A caliper housing having a caliper housing formed with a piston for pressing the inner plate toward the disc and a cylinder for receiving the piston at one side and a finger portion for pressing the outer plate toward the disc at the other side, Pad and the above Utteo pad is formed from a different material.

The inner pad may be formed of a low-steel material, and the outer pad may be formed of a NAO material.

The inner pad and the outer pad may be formed with inclined surfaces.

According to the present invention, a friction pad made of a low-steel material is applied to the inner plate disposed on the inboard side, and a friction pad made of NAO material is applied to the outer plate disposed on the outboard side, The disadvantages are reduced and the advantages for each material are applied at the same time, thereby increasing the efficiency and improving the braking performance.

2 is a front view showing an inner pad and an outer pad of a caliper brake for an automobile according to an embodiment of the present invention.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view schematically showing an automotive caliper brake according to an embodiment of the present invention, and FIG. 2 is a front view showing an inner pad and an outer pad of an automotive caliper brake according to an embodiment of the present invention.

Referring to FIG. 1, a caliper brake for an automobile according to an embodiment of the present invention includes a disc 2, an inner plate An inner plate 61 which is attached to the front surface of the inner plate 31 to generate a braking force when the disk 2 is brought into close contact with the disk 2 and an outer plate 33 which is disposed on the outboard side, An outer pad 63 which is attached to the front surface of the outer plate 33 and which is in close contact with the disk 2 together with the inner pad 61 to generate a braking force, A caliper 4 is formed on one side of the piston 4a and a cylinder portion 4 on one side thereof for receiving the piston 4a and a finger 5 for pressing the outer plate 33 to the side of the disk 2 is formed on the other side. And a housing (1).

More specifically, the automotive caliper brake includes a disk 2 rotating together with a caliper housing 1 and a wheel (not shown), and a pair of pad plates 31 and 33 provided on both sides of the disk 2. [ Respectively. The caliper housing 1 includes a cylinder portion 4 provided at one side and a finger portion 5 provided at the other side and connected to the cylinder portion 4. The pair of pad plates 31 and 33 are connected to the cylinder portion 4 ) And the ping rejection (5). Friction pads 61 and 63 are provided inside each of the pad plates 31 and 33 and a disc 2 is provided between the friction pads 61 and 63. A piston 4a capable of moving back and forth is incorporated in the cylinder 4 and an inner seal 4b made of an elastic material for restoring the piston 4a is provided on the inner circumferential surface of the cylinder 4 when the braking oil pressure is released .

Such a caliper brake of the present automobile is used when the driver depresses a brake pedal (not shown) and the hydraulic pressure formed in the master cylinder (not shown) is transmitted to the caliper housing 1 by a power unit (not shown) The fingers 5 on the side opposite to the cylinder portion 4 connected to the cylinder portion 4 by the hydraulic pressure remaining in the cylinder portion 4 move to the inner side And pushes the outer plate 33 on the fingering reed 5 side.

As a result, the two friction pads 61 and 63 on the inner side of the pad plates 31 and 33 press the disc 2 positioned therebetween to brak. When the driver releases his / her foot from the brake pedal (not shown), the piston 4a is restored to its original position due to the elastic force of the seal 4b, and the inner pad 61 and the finger 5, The outer pads 63 are spaced apart from the disk 2 by a predetermined distance.

Here, the inner pad 61 and the outer pad 63 of the automotive caliper brake are formed of different materials. More specifically, the inner pads 61 disposed on the inboard side may be formed of a low-steel material, and the outer pads 63 disposed on the outboard side may be formed of a NAO material.

In other words, by applying the friction pad formed of low steel material and NAO material at the same time to the caliper brake of this automobile, the disadvantages of the low steel material and the NAO material are reduced by half, the strength and the friction coefficient are excellent, And the advantage of each material having little noise during braking is simultaneously applied, thereby increasing the efficiency and improving the braking performance.
