Further, guide rods 46 are provided at both ends of the caliper housing 40 so that the caliper housing 40 can be slidably coupled to the carrier 30, and the guide rod 46 is provided with the guide rod 46. It is inserted into the guide hole 31 of the carrier 30 formed at a position corresponding to the.

The carrier 30 is firmly mounted to a knuckle (not shown) of the vehicle body through a mounting bolt (not shown), which prevents the pair of pad plates 20a and 20b from detaching and It serves to support the operation of the pad plate (20a, 20b).

As described above, both ends of the carrier 30 are provided with guide holes 31 into which the guide rods 46 are inserted. The guide hole 31 is formed to penetrate both ends of the carrier 30.

In addition, guide portions 32a and 32b are formed inside the carrier 30 so as to protrude so that the pair of pad plates 20a and 20b can be installed, and the pair of pad plates 20a and 20b are formed on the carrier 30. Installation grooves 22a and 22b are formed to be recessed inwardly so as to engage with the guide portions 32a and 32b of the 30.

Here, the pair of pad plates 20a and 20b may include an inner pad plate 20b having an outer surface in contact with the tip of the piston 42 and an outer pad plate having an outer surface in contact with the finger portion 43. 20a).

In addition, between the carrier 20 and the pair of pad plates 20a and 20b, the pair of pad plates 20a and 20b may be shaken during the smooth movement of the pair of pad plates 20a and 20b and the vibration of the vehicle. To prevent the pad spring 50 is installed.

Pad spring 50 is formed of a thin iron plate having a predetermined elasticity. The pad spring 50 includes two support parts 51 on both sides provided to support the pair of pad plates 20a and 20b, and a connection part 52 connecting upper ends of the two support parts 51.

At this time, the guide portion so as to be accommodated in the installation grooves (22a, 22b) formed at both ends of the pad plate (20a, 20b) in the state of being fitted to the guide portion (32a, 32b) of the carrier 30 in the two support portion (51) Protrusions 53 corresponding to the shapes of 32a and 32b are provided.

Reference numeral 35 is a main beam 35 formed in the carrier 30 to withstand the torque applied from the disk 10 during braking of the disc brake.

Meanwhile, in the exemplary embodiment of the present invention, the rigidity of the carrier 30 may be secured to the outside of the carrier 30 to withstand the torque applied from the disc 10 together with the main beam 35 when the disc brake is braked. Has a structure.

To this end, the first LM guide connecting portion 34 having a shape bent upward from the inner end of the portion 33 protruding toward the front surface of the carrier 30, as shown in Figs. Are each formed.

As described above, the finger portion 43 of the caliper housing 40 is formed to be bent downward from one end of the cylinder portion 41 so as to support the rear surface of the outer pad plate 20a during braking of the disc brake.

On both sides of the finger portion 43 of the caliper housing 40, the first LM guide connecting portion 34 of the carrier 30 and the LM guide connecting portion 44 connected to the LM guide are respectively formed at the brake of the disc brake.

That is, in the embodiment of the present invention by providing the first LM guide connecting portion 34 formed on both ends of the carrier 30 and the second LM guide connecting portion 44 formed on both sides of the finger portion 43 of the caliper housing 40, The braking of the disc brake may prevent deformation of the carrier 30 together with the main beam 35.

In addition, the conventional carrier 30 and the caliper housing 40 is made of a metallic material. Accordingly, damage may occur in the LM guide connection structure between the carrier 30 and the caliper housing 40 according to the sliding movement of the caliper housing 40 when the disc brake is braked.

In order to prevent this, in the embodiment of the present invention, as shown in FIGS. 3 and 4, the clip member 60 is mounted on at least one of the first LM guide connection part 34 and the second LM guide connection part 44. The clip member 60 is provided so that the Teflon material is coated so that the first LM guide connecting portion 34 and the second LM guide connecting portion 44 are damaged when the caliper housing 40 is slid and moved when the disc brake is braked. Can be prevented.

That is, in the embodiment of the present invention, the clip member 60 may be provided to surround the first LM guide connection part 34 or may be provided to surround the second LM guide connection part 44.

In addition, the LM guide connection structure between the carrier 30 and the caliper housing 40 having the above structure is disposed such that the first LM guide connecting portion 34 and the second LM guide connecting portion 44 are spaced apart at a predetermined interval when not braking.

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 40.

By the braking hydraulic pressure, the piston 42 of the cylinder portion 41 provided on one side of the caliper housing 40 pushes the inner pad plate 20b. Subsequently, the caliper housing 40 is retracted by braking hydraulic pressure. Accordingly, the finger portion 43 provided on the other side of the caliper housing 40 pushes the outer pad plate 20a.

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

At this time, the stress and deformation may be generated in the carrier 30 by the torque generated by the rotation of the disk 10, the main beam 35 formed on the carrier 30 and the second LM of the caliper housing 40 Due to the LM guide connection structure between the guide connection part 44 and the first LM guide connection part 34 of the carrier 30, deformation of the carrier 30 can be prevented.

For example, the second LM guide connecting portion 44 of the caliper housing 40 formed on the left side pushes the first LM guide connecting portion 34 of the carrier 30 formed on the left side in the left direction, and the caliper housing formed on the right side ( Similarly, the second LM guide connecting portion 44 of 40 may pull the first LM guide connecting portion 34 of the carrier 30 formed on the right side in the right direction.

In addition, in the embodiment of the present invention, when the finger 43 of the caliper housing 40 pushes the outer pad plate 20a when the disc brake is braked, the first LM guide connecting portion 34 of the carrier 30 and the caliper housing ( Since at least one of the second LM guide connecting portions 44 of the clip member 60 coated with a Teflon material is provided, damage to the first LM guide connecting portion 34 and the second LM guide connecting portion 44 may be prevented.
