BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc brake, and more particularly, to a disc brake capable of reducing uneven wear of a pad during braking operation.

Generally, a disc brake mounted on a vehicle is a device for decelerating, stopping, or maintaining a stopped state of an automobile while driving. A disc-shaped disc rotating together with the wheel is strongly urged by pads from both sides to obtain braking force.

Such a disc brake generally has a caliper housing in which a piston is built so as to move back and forth by a braking oil pressure, a carrier provided with a pair of pad plates to which pads are attached and fixed to the vehicle body, And a disk rotating with the wheel while being inserted.

The caliper housing is provided at its rear portion with a piston which is advanced and retreated by braking hydraulic pressure to push the pad plate at one side and a bent finger portion integrally formed at the front portion of the caliper housing to surround the other pad plate, do.

The carrier is mounted on the knuckle of the vehicle body through bolts, and two pad plates are slidably installed on the inner side. A pad spring is provided between the pad plate and the carrier so that the pad plate smoothly moves.

When the driver depresses the brake pedal, the brake fluid pressure generated by the master cylinder pushes the piston plate and the finger portion of the pad plate. The both pad plates slide along the pad spring fixed to the carrier, Braking.

That is, when the brake pedal is depressed, the piston in the cylinder pushes the inner pad toward the disk, the inner pad comes into contact with the disk, and the housing slidably engaged with the carrier fixed to the body is moved toward the inner pad.

As the housing is moved toward the inner pad, the outer pads supported and guided by the carrier come into contact with the disk, and the inner and outer pads press and rub against both sides of the disk by the housing and the carrier.

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

The embodiments described below are provided by way of example so that those skilled in the art will be able to fully understand the spirit of the present invention. The present invention is not limited to the embodiments described below and may be embodied in other forms. In order to clearly explain the present invention, parts not related to the description are omitted from the drawings, and the width, length, thickness, etc. of the components may be exaggerated for convenience. Like reference numerals designate like elements throughout the specification.

FIG. 1 is an exploded perspective view of a disk brake according to an embodiment of the present invention. FIG. 2 is an enlarged perspective view of a projection 22 of a pad plate 20 of a disk brake according to an embodiment of the present invention. 2 is a cross-sectional view showing an enlarged view of bb in Fig.

1, a part of a disk 10 rotating together with a wheel (not shown) is supported by a pad plate 20 to which a friction pad 21 is attached and a disk 10, And a caliper housing (40) slidably engaged with the carrier (30). The carrier (30) is fixed to the body (30).

The caliper housing 40 is provided with a cylinder portion 41. The cylinder portion 41 is moved forward and backward in accordance with the braking oil supplied from a master cylinder (not shown) A piston 42 for pressing the piston 42 is provided.

A finger pad 43 is provided on the other side of the caliper housing 40 so that the other pad plate 20a can slide toward the disk 10 with the sliding movement of the caliper housing 40. [

At both ends of the caliper housing 40 are provided guide rods 44 that allow the caliper housing 40 to be slidably engaged with the carrier 30 and are provided at both ends of the carrier 30 at positions corresponding to the guide rods 44 And a sliding hole 31 into which the guide rod 44 is slidably inserted.

Further, a carrier 30 is provided under the caliper housing 40 to prevent the pad plate 20 from coming off and to support the operation of the pad plate 20.

The carrier 30 is formed with a plurality of beams 33, 34 to withstand the torque applied from the disk 10 during braking. The plurality of beams 33 and 34 includes an auxiliary beam 33 connecting between the pair of receiving portions 32 and a screw hole 35 for fixing the carrier 30 to the vehicle body, And a main beam 34 extending from the receiving portion 32b.

A pair of receiving portions 32 are formed at both inner ends of the carrier 30 so that two pad plates 20 can be installed. The receiving portions 32a and 32b of the carrier 30 are formed in the pad plate 20, A protruding portion 22 protruding laterally is provided.

2, the protrusion 22 protrudes from the end of the protrusion 22 in a direction in which the pad plate 20 slides, that is, at right angles to the pad 21 or at right angles to the opposite side of the pad 21, A portion 23 is provided.

2 and 3, the rotation preventing portion 23 is formed by a moment generated between the rotating disk 10 during braking operation and the pad 21 pressing the rotating disk 10, Can be implemented. The rotation preventing portion 23 prevents the rotation of the pad plate 20 during the braking operation, thereby reducing the occurrence of uneven wear, which is a phenomenon in which one side of the pad 21 is further worn.

The above-described structure of the anti-rotation portion 23 suppresses the occurrence of uneven wear of the pad 21, thereby reducing noise and vibration during braking operation, thereby improving the braking performance.

2, an elastic member 60 may further be provided between the accommodating portion 32 of the carrier 30 and the rotation preventing portion 23 of the pad plate 20. As shown in FIG.

Although the elastic member 60 as an embodiment of the present invention is applied to a spring of an elastic material as an example, the elastic member 60 may be made of various materials capable of acting as an elastic member.

2 and 3, the elastic member 60 has an engaging portion which is engaged to be fixed to the side surface of the protruding portion 22 and an engaging portion which is elastically provided between the rotation preventing portion 23 and the accommodating portion 32 . When the pad plate 20 is eccentrically biased by the braking operation, the resilient portion first comes into contact with the receiving portion 32, and then absorbs the impact according to the elastic force and the elastic restoring force. When the impact is relaxed in this way, the impact size of the rotation preventing portion 23 and the accommodating portion 32 is reduced, so that the durability of the rotation preventing portion 23 or the accommodating portion 32 can be improved. In addition, Can be reduced.

1, in order to prevent smooth movement of the pad plate 20 and vibration of the pad plate 20 when the vehicle vibrates, a plate-shaped pad spring 20 is provided between the carrier 30 and the pad plate 20, The pad spring 50 is provided with a pair of support portions 51 which are formed by forming a thin steel plate having a predetermined elasticity to support the two pad plates 20, A sliding portion 52 which is positioned between the receiving portion 32 of the carrier 30 and the receiving portion 32 of the carrier 30 to smooth the sliding of the pad plate 20 and a connecting portion 53 which connects the upper end of the pad spring 50 .

As described above, by providing the protruding portion provided with the anti-rotation portion and the elastic member on the pad plate, the disc brake according to the embodiment of the present invention frictionally presses the disc by the moment generated between the disc and the pad plate during braking operation The uneven wear phenomenon of the pad can be reduced.

Also, since the uneven wear phenomenon of the pad is reduced, the noise and vibration during braking operation can be reduced, and the braking performance can be improved as noise and vibration are reduced.
