Description of the Invention: [Technical Field] The present invention relates to a contra-directional brake caliper, and more particularly to a contra-directional brake caliper which can effectively prevent the occurrence of vibration noise. I Prior Art] Referring to FIG. 1 , FIG. 2 , FIG. 3 , and FIG. 4 , a conventional contra-directional brake caliper 1 mainly includes a first caliper cylinder 10 and a second caliper cylinder 20 . a first piston 31, a second piston 32, a first oil seal 41, a second oil seal 42, a receiving groove 50, a first brake to make a piece 61, a second brake to make a piece 62, a positioning Reed 70 and a positioning pin 80 ° As shown in Fig. 3, the first caliper cylinder 10 has a first oil chamber 11. The second caliper cylinder 20 is coupled to the first caliper cylinder 10, and the second caliper cylinder 20 has a second oil chamber 21. The second oil chamber 21 is opposed to the first oil chamber 11. Further, the first oil chamber 11 and the second oil chamber 21 each contain a brake oil (not shown). The first piston 31 is disposed in the first oil chamber 11 in a moving manner. The first oil seal 41 is coupled to the first caliper cylinder 10 (the inner wall), and the first oil seal 41 is sleeved on the (outer wall) of the first piston 31. Here, the first oil seal 41 is for preventing the brake oil in the first oil chamber 11 from leaking out of the first-cylinder block 10. The second piston 32 is disposed in the second oil chamber 21 in a moving manner. The second oil seal 42 is coupled to the second caliper cylinder 20 (the inner wall), and the 201038836 second oil seal 42 is sleeved on the (outer wall) of the second piston 32. Here, the second oil seal 42 is for preventing the brake oil in the second oil chamber 21 from leaking out of the second caliper cylinder 20. As shown in FIG. 2, FIG. 3 and FIG. 4, the accommodating groove 50 is formed between the first caliper cylinder 10 and the second caliper cylinder 20, and the accommodating groove 50 has a first wall surface 51 and A second wall 52. Here, the first wall surface 51 is opposed to the second wall surface 52, and the first wall surface 51 and the second wall surface 52 are located between the first oil chamber 11 and the second oil chamber 21, respectively.煞 As shown in Figs. 2 and 3, the first brake shoe 61 is coupled to the first piston 31, and the first brake shoe 61 is disposed in the accommodating groove 50. The second brake shoe 62 is coupled to the second piston 32, and the second brake shoe 62 is also disposed in the receiving groove 50. Here, the second brake carriage 62 is opposite and spaced apart from the first brake carriage 61, and a brake disc (not shown) may be disposed on the first brake carriage 61 and the second brake carriage. Between 62. ❹ As shown in FIGS. 2 and 4, the positioning reed 70 is disposed on the first brake coming block 61 and the second brake coming block 62, and the positioning reed 70 is abutted against the first brake. The film 61 (both ends) and the second brake are used to make the film 62 (both ends). The positioning pin 80 is simultaneously inserted into the first caliper cylinder 10, the second caliper cylinder 20, the first brake urging blade 61 and the second brake urging blade 62, and the positioning pin 80 is (downward) Pressed on the positioning reed 70. As described above, the first brake shoe 61 and the second brake shoe 62 are positioned in the accommodating groove 50 by the (downward) pressing action of the positioning pin 80 and the 201038836 positioning spring 70. As described above, since the first brake shoe 61 and the second brake shoe 62 are mounted in the accommodating groove 50, the blade 62 can be used to make the blade 61 and the second brake to enable the blade 62. Normally actuated or installed, the width of the receiving groove 50 must be greater than the width of the first brake blade 61 and the second brake blade 62. Therefore, as shown in Fig. 4, there will be two gaps d between the second brake shoe 62 and the first wall surface 51 and the second wall surface 52 of the accommodation groove 50. Similarly, there will be two gaps d between the first brake blade 61 and the first wall 〇 51 and the second wall 5.2 of the accommodating groove 50. As described above, when the opposite brake caliper 1 is in a vibrating environment, the first brake squeegee 61 and the second brake squeegee 62 are oscillated by the locating pin 80 as a fulcrum, respectively, and thus the impact accommodating The first wall surface 51 and the second wall surface 52 of the groove 50 generate an abnormal sound. In addition, when the first brake driving blade 61 and the second brake driving blade 62 are respectively driven by the first piston 31 and the second piston 32 to clamp the brake disk, the first braking device 61 and the second braking device The friction generated by the blade 62 in contact with the brake disc is greater than the friction between the first brake pedal 61 and the second brake pedal 62 in contact with the first piston 31 and the second piston 32, respectively. Therefore, the first braking device 61 and the second braking device 62 cause the driving blade 62 to be swung toward the one side by the rotating braking disk, thereby hitting the first wall surface 51 or the second wall surface 52 of the receiving groove 50, thereby further It will produce an impact noise. I. The invention is basically characterized by the features detailed below in order to solve the above.

More specifically, the two positioning protrusions 163 are formed on the flat portion 161, and the flat portion 161 of the reed 160 is respectively positioned in the two positioning holes 151a by the two positioning protrusions 163. The first wall surface 151 of the groove 150 is disposed. In addition, the through slot 164 is formed over the resilient meandering portion 162 which can be used to allow a drive disc (not shown) to penetrate. As shown in Figs. 6 and 7, the first brake carriage 171 is coupled to the first piston 131, and the first brake carriage 171 is disposed in the receptacle 90 201038836. In particular, the first brake slat 171 abuts between the elastic meandering portion 162 of the reed 160 and the second wall surface 152 of the accommodating groove 150. As shown in Figs. 6, 7, and 9, the second brake shoe 172 is coupled to the second piston 132, and the second brake shoe 172 is disposed in the accommodating groove 150. In particular, the second brake slat 172 is also abutted between the elastic meandering portion 162 of the reed 160 and the second wall 152 of the accommodating groove 150. In addition, the second brake slats 172 are opposite and spaced apart from each other, and the brake discs are disposed between the first brake slats 171 and the second brake shackles 172. As shown in FIGS. 6 and 7, the positioning pin 180 is simultaneously inserted into the first caliper cylinder 110, the second caliper cylinder 120, the first brake slap 171, and the second brake slap 172. It can be used to position the first brake to make the sheet 171 and the second brake to make the sheet 172. As described above, the flat portion 161 of the reed 160 is attached to the first wall surface 151 of the accommodating groove 150, and the elastic meandering portion 162 of the reed 160 is abutted against the first brake slap 171 and the second The brake lining 172 is used to apply the elastic force to the second wall surface 152 of the accommodating groove 150 by the first brake slap 171 and the second brake. Therefore, the first brake slap 171 and the second brake squeegee 172 are respectively abutted between the elastic meandering portion 162 and the second wall surface 152. As described above, even when the opposite brake caliper 100 is in a vibrating environment, the first brake slap 171 and the second brake slap 172 do not overlap the first wall 151 or the second wall 152 of the accommodating groove 150. An impact occurs, so that abnormal noise can be effectively avoided. * , 10 201038836 In addition, since the first brake 171 and the second brake 172 are respectively abutted between the elastic meander 162 and the second wall 152, the first brake 171 and the first The second carriage causes the sheet 172 not to be swung by the rotating brake disc, and thus does not hit the first wall surface 151 or the second wall surface 152 of the accommodating groove 150, so that no impact noise is generated. Although the present invention has been disclosed in its preferred embodiments, it is not intended to limit the present invention, and it is possible to make some modifications and refinements without departing from the spirit and scope of the present invention. The scope of the invention is defined by the scope of the appended claims.
