Description

DISC BRAKE}

The present invention relates to a disc brake, and more particularly to a disc brake to reduce the noise and vibration generated in the pad plate.

In general, a disc brake is a device for braking a vehicle by pressing both sides of a disc rotating with a wheel with a pad plate. The disc brake has a caliper housing and a piston for pressing the pad plates disposed on both sides of the disk toward the disk, and has a carrier mounted to the vehicle body for supporting the pad plates and the caliper housing.

The caliper housing is slidably coupled to the carrier by two guide rods coupled to both sides thereof, and the two pad plates are supported by the carrier so as to slide toward both sides of the disk. A pad spring is provided between the carrier and the pad plate to slidably support the pad plate and to prevent shaking of the pad plate.

In the disc brake, when the driver presses the brake pedal, a braking hydraulic pressure is formed in the master cylinder and transmitted to the piston. Accordingly, the two pad plates are advanced toward the disc to strongly press both sides of the disc, thereby braking the vehicle.

The pad springs elastically support the upper and lower surfaces of the end of the pad plate in a form surrounding the end of the pad plate. The pad plate slides along the contact surface with the pad spring in a state in which elastic force is applied from the pad spring. At this time, since there is no separate guide, vibration and noise of the up and down direction occur in the pad plate due to the elastic force of the pad spring.

The disc brakes therefore have guide means in the pad springs to reduce noise and vibration.

One aspect of the present invention discloses a disc brake to reduce the noise and vibration generated in the pad plate.

Disc brake according to the spirit of the present invention is a disk that rotates with the wheel of the vehicle, at least one pad plate disposed around the disk, the carrier is arranged to move the pad plate, the end of the pad plate A pad spring fixedly mounted to the carrier to elastically support the

The pad spring is characterized in that the guide portion for guiding the movement of the pad plate is formed.

The guide part may be a guide rail protruding toward the pad plate.

A rail groove may be recessed in a predetermined depth at an end portion of the pad spring to correspond to the shape of the guide rail.

The guide rail may be formed by bending the pad spring.

Since the pad plate can be slidably moved on the guide rail formed in the pad spring, noise and vibration generated when the pad plate moves can be reduced.

In addition, since the load applied to the pad spring is distributed to the elastic support points and the guide rails, noise generated in the pad spring can be reduced, and the pad plate can slide on the pad spring with a smaller force.

Figure 3 is a perspective view of the pad plate of the disc brake according to an embodiment of the present invention.

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

Disc brake according to an embodiment of the present invention, as shown in Figure 1, the caliper housing 50 and the pads (21a, 21b) that the piston 52 is built so as to move forward and backward by the braking hydraulic pressure is respectively attached A pair of pad plates (20a, 20b) is installed to be spaced apart at regular intervals, and a portion of the edge is inserted between the pair of pad plates (20a, 20b) to rotate with a wheel (not shown) A disk-shaped disk 10 is included.

Specifically, the caliper housing 50 includes a cylinder portion 51 in which a piston 52 is incorporated, a finger portion 53 for operating the outer pad plate 20a, which will be described later, and a finger portion 53 and a cylinder. And a connecting portion 54 for connecting the portion 51.

As described above, the cylinder portion 51 includes a piston 52. The piston 52 moves forward and backward according to the braking oil supplied from the master cylinder (not shown) and presses the inner pad plate 20b to the disc. Done. An inner circumference of the cylinder portion 51 may be provided with an elastic sealing member (not shown) for restoring the piston 52.

The finger portion 53 is formed to bend downward from the other side of the caliper housing 50 so as to support the rear surface of the outer pad plate 20a.

The connection part 54 connects the cylinder part 51 and the finger part 53 as mentioned above.

The carrier 40 is firmly mounted to a knuckle (not shown) of the vehicle body through mounting bolts (not shown), which prevent the separation of the pair of pad plates 20a and 20b and It serves to support the operation of the pad plates (20a, 20b).

In addition, a sliding portion 42 is formed in the inner side of the carrier 40 so that a pair of pad plates 20a and 20b may be installed, and a pair of pad plates 20a and 20b may be formed in the carrier 40. Coupling portions 22a and 22b protruding from the ends are provided to be coupled to the sliding portion 42.

Here, the pad plates 20a and 20b are attached to the inner surface of the outer pad plate 20a and the outer surface of the pad 21a, and the outer surface of the pad 21b is disposed to be in contact with the finger portion 53. And an inner pad plate 20b disposed to be in contact with the tip of 52.

Between the carrier 40 and the pair of pad plates 20a and 20b, the pair of pad plates 20a and 20b is smoothly moved and the pair of pad plates 20a and 20b are prevented from shaking when the vehicle is vibrated. The pad spring 30 is disposed in order to be fixed to the carrier 40.

The pad spring 30 is a connecting portion connecting two upper ends of the two support parts 32 and the two support parts 32 provided to support a pair of pad plates 20a and 20b by molding a thin steel plate having a predetermined elasticity. (31) and the pad spring 30 is composed of a mounting portion 33 is bent and extended on both sides of the support portion 32 and one side of the connection portion 31 to be fixed to the carrier 40.

In addition, a guide rail 34 is disposed on the pad spring 30 to guide sliding movement of the pad plates 20a and 20b. The guide rail 34 extends in the sliding directions of the pad plates 20a and 20b, and the pad plates 20a and 20b slide on the pad spring 30 along the guide rail 34.

The guide rail 34 protrudes toward the coupling portions 22a and 22b of the pad plates 20a and 20b, and the support portion 32 of the pad spring 30 is formed without using a separate member. 20b) is preferably bent and formed so as to protrude in the direction of the engaging portion (22a, 22b).

Rail grooves 23a and 23b corresponding to the shape of the guide rails are recessed in a predetermined depth in the coupling portions 22a and 22b of the pad plates 20a and 20b. Since the guide rail 34 of the pad spring 30 is accommodated in the rail grooves 23a and 23b, the pad plates 20a and 20b can be slidably moved.

Hereinafter, the operation and effect of the disc brake configured as described above will be described.

First, when the driver presses a brake pedal (not shown) while the vehicle is running, a braking hydraulic pressure is formed in the master cylinder (not shown) and the braking hydraulic pressure formed in the master cylinder is transmitted to the caliper housing 50.

By the braking hydraulic pressure, the piston 52 of the cylinder portion 51 provided on one side of the caliper housing 50 pushes the inner pad plate 20b, and the caliper housing 50 is subsequently retracted by the braking hydraulic pressure. Accordingly, the finger portion 53 provided on the other side of the caliper housing 50 pushes the outer pad plate 20a in the direction of the disk 10.

Therefore, the pads 21a and 21b of the pair of pad plates 20a and 20b press the disk 10 to brake by friction between the pads 21a and 21b and the disk 10.

At this time, in the embodiment of the present invention, the inner pad plate 20b and the outer pad plate 20a slide along the guide rail 34 formed in the pad spring 30 in the direction of the disk 10. Since the pad plates 20a and 20b are suppressed in the vertical and vertical directions in the moving direction, noise and vibration are reduced. In addition, since the loads of the pad plates 20a and 20b acting on the pad spring 30 are distributed to the elastic support points and the guide rails 34, the noise generated in the pad spring 30 is reduced, and the pads are made even smaller. The plates 20a and 20b can be slid.
