BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pad fixing structure of a caliper brake of an automobile. By fixing a back plate of an outer brake pad by a clip to a fork part, only the clip is removed when replacing the outer brake pad due to wear of the pad friction material. The present invention relates to a pad fixing structure of an automobile caliper brake that can replace a brake pad without removing the whole.

In general, a vehicle is provided with a braking device that serves to slow down or stop the vehicle speed while driving.

Such a braking device is a booster that doubles the pedal effort by using a vacuum pressure (engine suction pressure) generated by the power of an engine, and forms a pressure in each brake circuit and generates a volume of brake oil. It consists of a master cylinder that compensates for changes and quickly dissipates circuit pressure, and a wheel cylinder that stops the rotation of the wheel by the brake oil pressure and slows down the rotation speed.

The wheel cylinder is in close contact with the brake pad installed in the inner circumferential surface of the cylindrical drum synchronously rotating with the wheel wheel to generate a braking force, or close to the brake pad to the disk-shaped disk synchronously rotating with the wheel wheel The brakes are installed in the caliper brakes that generate the braking force.

Here, a typical example of the caliper brake is illustrated in FIGS. 1 to 3, which will be briefly described as follows.

The caliper brake 100 slides on both sides of the brake disk, which is installed to be synchronized with the wheel wheel while being secured to the inner knuckle arm of the wheel wheel, as shown. The inner and outer brake pads 130 'and 130 are formed by the caliper bracket 120 having the inner and outer brake pads 130' and 130 and the hydraulic piston 113 according to the hydraulic pressure. It is largely composed of a caliper body (110) sliding through the caliper bracket 120 to contact the disk.

In addition, the wheel cylinder 111 is formed in the center of the caliper body 110 in the sliding direction of the inner brake pad 130 ', and the hydraulic piston 113 is installed in the wheel cylinder 111, the wheel The inner brake pad 130 'located inside the disk is slid to the disk side by the hydraulic pressure injected into the cylinder 111.

At the lower end of the caliper body 110, the fork part makes contact with the outer surface of the disk with the outer brake pad 130 located on the outer side of the disk in response to the hydraulic piston 113 when the hydraulic piston 113 is operated. 140 extends toward the outer brake pad 130 to support the rear surface thereof.

When the caliper brake is configured as described above, the pressure of the vacuum booster acting as the foot pedal is pressed down causes the brake oil of the master cylinder to flow into the wheel cylinder 111 of the caliper body 110. Inject.

At this time, the hydraulic piston 113 advances by the injected brake oil and closely adheres the brake pads 130 'positioned inside to the disk.

While the inner brake pad 130 ′ is in close contact with the disc, the caliper body 110 reacts backward with respect to the forward action of the hydraulic piston 113 by the pressure of the brake oil.

At this time, the caliper body 110 forms a sliding movement to the rear. The fork 140 formed at the lower portion of the caliper body 110 moving backwards closes the outer brake pads 130 located on the outer side of the disk.

 The disk contact of the inner and outer brake pads 130 'and 130 in the above process is to stop the rotational movement of the disk or to reduce the rotational speed through the friction force.

However, in the caliper brake as described above, after the brake is released, the inner brake pad 130 ′ interposed on the wheel cylinder 111 side and the outer brake pad 130 interposed on the fork 140 side of the caliper body 110. ) Should be returned to normal, fork 140 of the caliper body 110 and the outer brake pad 130 in contact therewith are coupled to each other through the uneven structure.

The uneven structure is a pad fixing protrusion 131a which is integrally protruded at positions corresponding to each other on the back plate 131 rear surface of the outer brake pad 130 so that the fork part 140 and the outer brake pad 130 move synchronously. ) And an insertion hole 140a which is formed in a concave indentation by a predetermined depth from one side of the fork 140 contacting the back plate 131 and is coupled to the pad fixing protrusion 131a.

As described above, the pad fixing protrusion 131a of the back plate 131 is inserted into and fixed to the insertion hole 140a of the fork 140 so that the fork 140 may be removed by the fork 140 when the brake is released. And the outer brake pads 130 fixed in close contact with each other, the outer brake pads 130 can be prevented from being dragged or noise caused by the outer brake pads coming into contact with the disc even after the brake is released, and premature wear of the pad friction material due to the drag phenomenon. The life of the outer brake pad can be prevented from being shortened.

However, since the pad fixing protrusion 131a of the back plate 131 of the outer brake pad 130 is tightly inserted into and fixed to the uneven structure as described above, that is, the insertion hole 140a of the fork part 140, Problems due to the return of the brake pad 130 can be solved but cause other problems.

That is, due to the above structure in which the pad fixing protrusion 131a is tightly inserted into and fixed to the insertion hole 140a, the pad friction material 133 of the outer brake pad 130 wears out due to frequent brake operation, thereby extending its life. Since it is necessary to replace the outer brake pad 130.

At this time, since the outer brake pad 130 is fixed to the fork 140, a problem arises in that the entire caliper brake 1 needs to be removed to replace the outer brake pad 130.

This not only significantly increases the time required for the brake pad replacement work, but also increases the number of working steps as the caliper brake is removed, which is very inefficient.

Accordingly, the present invention has been made to solve the above problems, by removing the clip for fixing the back plate of the outer brake pad to the fork portion, thereby replacing the brake pad during replacement of the outer brake pad due to wear of the pad friction material. It is an object to provide a pad fixing structure of an automobile caliper brake which can be replaced very easily.

The pad fixing structure of the caliper brake of the vehicle according to the present invention for achieving the above object, the pads formed integrally protruding from each of the inner and outer brake pads at positions corresponding to each other on both sides of the back plate rear surface of the outer brake pad, respectively. In the pad fixing structure of the caliper brake is formed by the fixing projection and the projection insertion hole formed in the concave from one side of the fork portion to correspond to the pad fixing projection in the circumferential direction, includes a depression formed in the circumferential direction on the lower side Clip fixing protrusion integrally formed at the rear center portion of the back plate, and a coupling portion coupled to the circumferential direction at the bottom of the clip fixing protrusion and a circular groove at the upper end are formed with a circular groove. With clips containing support pieces seated on top It is characterized in that formed.

At this time, the diameter of the groove of the support piece is a size corresponding to the diameter of the projection insertion hole of the fork portion, the projection insertion hole of the fork portion may further include an expansion pipe formed extending from the central portion to the upper end.

And it is preferable to form the groove of the said support piece in the magnitude | size corresponding to the diameter of the expansion pipe part of the said fork part.

As shown in FIGS. 4 to 7, the pad fixing structure of the caliper brake of the vehicle according to the first embodiment of the present invention includes the outer brake pad 30 among the inner and outer brake pads 30 ′ 30. ) Includes the pad friction material 33 and the back plate 31.

In the rear center portion of the back plate 31, a clip fixing protrusion 31a including a recessed portion 31b recessed in the circumferential direction is formed integrally protruding.

In addition, the clip 50 is provided over the depression 31b of the clip fixing protrusion 31a and the upper end of the protrusion insertion hole 40a of the fork 40, thereby providing the bag with the bag 40. The plate 31 is effectively fixed.

The structure in which the clip 50 fixes the back plate 31 with respect to the fork portion 40 will be described in detail by dividing it into upper and lower portions according to its shape.

First, as a structure for fixing the back plate 31 at the lower end, the engaging portion 51 is coupled to the recessed portion 31b of the clip fixing protrusion 31a in the circumferential direction, wherein the coupling portion ( 51 has a shape that is bent upward by the height of the depression (31b) to be effectively coupled to the depression (31b).

In addition, a support piece 53 having a circular groove having a diameter equal to the diameter of the protrusion insertion hole 40a of the fork part 40 is formed at the upper end of the protrusion insertion hole of the fork part 40. By being seated and coupled to the top 40a, the backplate 31 is fixed to the fork 40 by the clip 50 having a very large bearing force on the principle of the lever.

Therefore, as described above, by effectively fixing the outer brake pad 30 to the fork portion 40 by the clip 50, the drag phenomenon due to the return of the outer brake pad 30 when the brake is released or There is an advantage that can prevent the noise and vibration caused by the remaining state of contact with the brake disc.

In addition, when the pad friction material 33 of the outer brake pad 30 needs to replace the outer brake pad 30 at the end of its service life, the entire clip of the caliper brake 1 is not removed. Since only the 50) can be removed, the outer brake pad 30 can be replaced very easily, and since the caliper brake 1 is not removed, the number of working steps can be reduced, and the convenience of work can be achieved. The time required for the reduction can be saved.

On the other hand, as shown in Figure 8, the projection insertion hole (40a) of the fork portion 40 may further include an expansion pipe portion (40b) formed to extend from the center portion to the upper end, accordingly the fork portion ( It is preferable to form grooves of the support piece 53 in a size corresponding to the diameter of the expansion pipe portion 40b of 40).

In addition, a support piece 53 'having a circular groove having a diameter equal to the diameter of the protrusion insertion hole 40a of the fork part 40 is formed at the upper end of the protrusion insertion hole 40a of the fork part 40. By being seated and coupled to the top, the backplate 31 is fixed to the fork 40 by the clip 50 'with a very large bearing force based on the principle of leverage.

Therefore, as described above, by effectively fixing the outer brake pad 30 to the fork portion 40 by the clip 50 ', the drag phenomenon due to the return of the outer brake pad 30 when the brake is released. However, there is an advantage of preventing noise and vibration caused by the remaining state of contact with the brake disc.

In addition, when the pad friction material 33 of the outer brake pad 30 needs to replace the outer brake pad 30 at the end of its service life, the entire clip of the caliper brake 1 is not removed. Since only 50 ') can be removed, the outer brake pad 30 can be replaced very easily, and since the caliper brake 1 is not removed, the number of working steps can be reduced, thereby facilitating work. The time required for the reduction of the number of processes can be saved.

On the other hand, as shown in Figure 11, the projection insertion hole 40a of the fork portion 40 may further include a expansion pipe portion (40b) formed to extend from the center portion to the upper end, accordingly the fork portion ( It is preferable to form grooves of the support piece 53 'in a size corresponding to the diameter of the expansion pipe portion 40b of 40).

The structure in which the clip 50 "fixes the back plate 31 to the fork 40 is divided into upper and lower parts according to the shape thereof, as follows.

First, the lower plate has a structure for fixing the back plate 31, the insertion portion 61 of the clip fastening portion 60 penetrates the insertion hole 31e and the through hole 54 "upwards. After being coupled, the upper part of the insertion part 61 is subjected to a riveting process to form a riveting part 61a, whereby the clip fastening part 60 is preferably coupled to the back plate 31. .

At this time, the through hole 54 "is formed through the diameter of the same size as the insertion hole 31e.

In addition, a support piece 53 "having a circular groove having a diameter equal to the diameter of the protrusion insertion hole 40a of the fork part 40 is formed at the upper end of the protrusion insertion hole 40a of the fork part 40. By being seated and coupled to the top, the backplate 31 is fixed to the fork 40 by the clip 50 ", which has a very large bearing force on the principle of leverage.

Therefore, as described above, by effectively fixing the outer brake pad 30 to the fork portion 40 by the clip (50 "), the drag phenomenon due to the return of the outer brake pad 30 at the time of brake release However, there is an advantage of preventing noise and vibration caused by the remaining state of contact with the brake disc.

In addition, when the pad friction material 33 of the outer brake pad 30 needs to replace the outer brake pad 30 at the end of its service life, the entire clip of the caliper brake 1 is not removed. Since only 50 ") can be removed, the outer brake pad 30 can be replaced very easily. Therefore, since the caliper brake 1 is not removed, the number of working steps can be reduced and the convenience of work can be achieved. The time required for the reduction can be saved.
