Description

Disk Brake for vehicle

The present invention relates to a disc brake for a vehicle, and more particularly to a disc brake having a sensor for determining the wear of the friction pad of the disc brake for vehicles.

In general, a disc brake for a vehicle is a device that obtains a braking force by strongly pressing a disk-shaped disk that rotates with the wheel of the vehicle with a friction pad on both sides.

The conventional vehicle disc brake has a pair of pad plates 2 and 3 having friction pads 2a and 3a attached to both sides of the disk 1 rotating together with the wheels, as shown in FIG. The pad plates (2, 3) are supported by the carrier (4) fixed to the knuckle portion (not shown) of the vehicle, and are installed to be able to move forward and backward on the disk (1) side.

In addition, the inner side of the carrier plate 4 to the two pad plates (2, 3) disposed on both sides of the disk 1 toward the disk 1, the inner pad plate (2) on one side of the disk (1) A caliper having a cylinder portion 6 provided with a piston 4 to pressurize toward the side and a finger portion 7 for pressing the outer pad plate 3 opposite the cylinder portion 6 toward the disk 1 on the other side. The housing 8 is provided.

In addition, in the vehicular disk brake having the structure as described above, when the friction pads 2a and 3a rub against the disk 1 on one side of the inner pad plate 2 and are worn over a certain level, they hit the disk 1 and make noise. The wear detection sensor 9 informing the timing of the replacement of the friction pads 2a and 3a is fixed by bolts.

However, the above-described method of installing the wear detection sensor 9 has to be provided in advance in the inner pad plate 2 for installing the wear detection sensor 8, unnecessary space and cost when processing the shape of the pad plate There was a problem. In addition, since the wear detection sensor 9 has an R-shape, there is a problem that manufacturing is not easy.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a disc brake for a vehicle that can be easily assembled and reduce manufacturing costs by improving a wear detection sensor.

The disk brake for a vehicle according to the present invention for achieving the above object is a disk that rotates together with a wheel, a carrier fixed to the vehicle body and provided with a pair of pad plates, and a finger portion on one side to press the pair of pad plates toward the disk side. And a caliper housing provided with a cylinder on the other side, a friction pad partitioned on each pad plate, and a wear detection sensor provided on the pad plate to protrude between the divided friction pads to indicate when to replace the friction pad.

In addition, the wear detection sensor of the vehicle disk brake according to the invention is riveted to the pad plate.

The disk brake for a vehicle according to the present invention has an effect of avoiding the time and cost required to process the position of the wear detection sensor on the pad plate by installing a wear detection sensor between friction pads that are dividedly provided on the pad plate. .

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

2 is a view showing a vehicular disk brake according to the present invention, Figures 3 and 4 are a front view and a plan view showing a pad plate of the disk brake. Referring to the drawings, a pair of pad plates 20 and 30 to which friction pads 21 and 31 are attached are provided on both sides of the disk 10 which rotates together with the wheels of the vehicle.

The pad plates 20 and 30 are supported by a carrier 40 fixed to a knuckle portion (not shown) of the vehicle, and the support portions 22 and 32 formed at both ends of each pad plate 20 and 30 correspond to this. By being fitted into the seating grooves 41 formed on both sides of the carrier 40, the pad plates 20 and 30 are supported to be able to move forward and backward to the disk side. The support parts 22 and 32 are provided with pad springs 25 so as to damp vibrations generated in the pad plates 20 and 30 by a braking action.

In addition, the outer side of the carrier 40 is provided with a caliper housing 50 for pressing the two pad plates (20, 30) disposed on both sides of the disk 10 toward the disk 10 side.

One side of the caliper housing 50 is provided with a cylinder portion 51 is provided with a piston 60 to press the inner pad plate 20 toward the disk 10, the other side of the cylinder portion 51 is opposite the outer pad plate The finger part 52 which supports the back surface of 30 is provided.

In addition, guide rods 53 are provided at both sides of the caliper housing 50 so that the caliper housing 50 can be slidably coupled to the carrier 40, and guide rods 53 are provided at both sides of the carrier 40. Guide holes 42 are formed to guide the guide rods 53.

On the other hand, the friction pads (21, 31) provided in each of the pad plate (20, 30) is usually divided into two to be mounted to the pad plate (20, 30) in order to reduce noise tuning and changes in the friction material volume at high temperatures. That is, as shown in FIGS. 2 to 4, the friction pads 21 and 31 are divided into the same size on both sides with respect to the center side of the pad plates 20 and 30, and the empty space therebetween is provided as a slot ( 26).

According to the present invention, the wear detection sensor 70 for determining the wear level of the friction pad 21 is riveted after drilling the pad plate 20 in the slot 26 between the divided friction pad as described above It is attached to the pad plate 20 by doing so. When installed in this way, the shape of the wear detection sensor 70 can be simplified in the form of a bar to reduce the manufacturing cost of the sensor, the position of the wear detection sensor 70 to be provided in advance on the pad plate 30 Since there is no need, the pad plate 30 can be easily processed.

In the present exemplary embodiment, the wear detection sensor 70 is illustrated as being provided only on one side support part 22 of the inner pad plate 20, but if necessary, the wear detection sensor 70 is installed on the support part 32 of the outer pad plate 30 or one or more. It is also possible to install.

This will be described in detail the operation and effects of the vehicular disk brake according to the present invention configured as described above.

First, when the driver presses a brake pedal (not shown), a braking hydraulic pressure is formed, which is transmitted to the cylinder portion 51 to advance the piston 60. Then, the inner pad plate 20, which is installed in the carrier 40 so as to move forward and backward, moves forward and toward the disk 10, and the one side surface of the disk 10 and the inner friction pad 21 that rotate rotate to friction.

At the same time, the caliper housing 50 which is slidably coupled through the guide rod 53 is moved opposite to the operation direction of the piston 60 by the hydraulic pressure remaining in the cylinder portion 51. Then, the finger portion 52 pushes the outer pad plate 30, and thus the outer friction pad 31 is pressed against the other side of the disk 10 to generate a braking force.

When such a braking action is repeatedly performed, the friction pads 21 and 31 are worn out due to friction with the disk 10. When the friction pads 21 and 31 are worn over a certain amount, the wear detection sensor 70 may be a disk ( 10) and the noise is generated accordingly to know the replacement time of the friction pad (21, 31).
