Description of the Invention: [Technical Field] The present invention relates to a floating brake caliper, and more particularly to a floating brake caliper capable of effectively suppressing vibration noise. [Prior Art] Please refer to FIG. 1 , FIG. 2 and FIG. 3 . A conventional floating brake card sweet 1 mainly includes a “barrel cylinder 10 , a piston 20 , an oil seal 30 , and a first brake . The order piece (inner car to make a piece) 41, a second car to make a piece (outer car to make a piece) 42, two positioning pins 50, a fixing frame 60 and a positioning reed 70. The caliper cylinder 10 has an oil inlet port 11 and an oil chamber 12. The oil inlet port 11 is connected to the oil chamber 12. In addition, the oil inlet port 11 is connected to a master cylinder (not shown), and the brake master cylinder, the oil inlet port 11 and the oil chamber 12 are each housed with brake oil (not shown). As shown in Fig. 3, the piston 20 is disposed in the oil chamber 12 in a moving manner. The oil seal 30 is attached to the inner wall of the caliper cylinder 10, and the oil seal 30 is sleeved on the (outer wall) of the piston 20. Here, the oil seal 30 is for preventing the brake oil in the oil chamber 12 from leaking out of the caliper cylinder 10. The first brake car (the inner brake) 31 is adjacent to the piston 20. Here, as shown in FIG. 3, the positioning spring 70 is abutted between the caliper cylinder 10 and the first brake shoe 41, so that the first brake shoe 41 can be positioned on the fixing frame 60. on. In other words, the first brake comes to the piece 6 1335964 to position the reed. The 7G is for the (downward) pressing force and the second to make the piece (the outer car to the piece) 42 is abutting the card sweet cylinder J The inner wall" and the second brake block 42 are 7 pieces 4i with respect to the first brake. Here, as shown in Fig. 4 and Fig. 4, the two clamps are disposed on the caliper cylinder 10 and fixed. Frame 6 and the second brake come = = will: the clamp red body 1 〇, the fixed frame 6 〇 and the second: the car to make the month 42, 纟. Together, in addition, as shown in Figure 3, the positioning abuts The caliper cylinder 10 and the second brake squeegee 42 & 疋 second brake squeegee 42 are attached to the caliper cylinder 1 (the inner wall) by the positioning reed 70 In addition, the disc H-brake to make the piece 41 and the second brake to make the piece and the mouth establish the oil pressure, the brake oil will be overcome by the oil intake: the second push the piston 2 〇. Here, the piston 2 moves to the right (rightward) and pushes (adjacent to the piston 41 (to the right). When the first brake causes the sheet to be affected by one side surface, the whole The caliper cylinder 10 is the first to brake the disc 42 against the brake disc 2. At this time, the first brake pedal 41 and the second other side surface clamp the brake disc D to achieve the brake braking effect H piece 42, that is, the Sega nuclear oil seal is 3 G. 7The seal will occur by the seal 30. When the brake master cylinder is released and the brake oil disappears, the live 7 1335964 plug 20 will reverse (to the left) due to the return spring provided by the oil seal 30, thus forcing the oil A portion of the brake oil in the chamber 12 flows into the brake master cylinder, thereby causing the first brake to cause the sheet 41 and the second brake to cause the sheet 42 to no longer grip the brake disc D. Here, the first brake disc 41 and the second brake disc 42 are also separated from the brake disc D by the rotation of the brake disc D. However, since the first brake shoe 41 is positioned on the fixed frame 60 only by the (downward) pressing force provided by the positioning reed 70, the first brake is generated without the brake hydraulic pressure being established. The sheet 41 has a gap between the piston 20 and the disc D. Therefore, when the floating brake caliper 1 is in a vibrating environment, the first brake causes the sheet 41 to strike with the piston 20 and the brake disc D, thereby generating noise. In view of the above, it is an object of the present invention to provide a floating brake caliper which can effectively suppress noise generated by vibration.

The first liner 141 is coupled to the first friction material plate 142, and the first liner 141 is positioned between the piston 120 and the first friction material plate 142. The through hole 143 is formed in the first lining plate 141 and the first friction material plate 142, and the through hole 143 is a screw hole 121 corresponding to the piston 12 。. The resisting portion 141a is formed over the first lining plate 141, and the resisting portion i4u surrounds the through hole 143. Further, as shown in Fig. 7, the positioning reed can also selectively abut between the caliper cylinder 110 and the first brake lining 14 。. 7 As shown in Fig. 7, the bolt 15 is locked to the screw hole 121 of the piston 12 via the through hole (4) of the first car. The pin 150 is abutted against the first brake to cause the piece 14 The snail-to-spindle (10) is pressed against the piston 12. . Seven (10), so that the second brake comes to the film (the outer brake to make the film) 16 body 110, and the second brake to make the film 160 is relative to the first:::: piece 140. Here, as shown in Fig. 5 and Fig. 7, the rain ~..., the car π is simultaneously placed on the caliper cylinder 11 (), and the fixed frame is the reading pin 170 is a brake to the piece 1335964 160, Therefore, the caliper core body 11 and the fixing frame 18 can be combined to make the sheets 160 joined together. Further, as shown in Fig. 7, the positioning 190 is abutted between the caliper cylinder 11 〇 and the second brake lining. In other words, the second brake causes the sheet to abut against the caliper cylinder 11 (the inner wall) by the pressing force of the positioning spring. In addition, the brake disc D is disposed between the first and second brake discs 14 (). - Early arrival When the brake mains is established - the brake oil is applied, the brake oil flows into the oil chamber 112 via the inlet port 111, thereby pushing the piston 120. Here, live f = against the resistance of the oil seal 130 (to the right), and then pushes (against the piston 120) the first brake to move #14〇 (to the right). When the first brake shoe 140 (the first friction material plate 142) abuts against one side surface of the brake disk D, the entire caliper cylinder 110 is reversed (to the left) due to the reaction force until ( The second brake abutting the caliper cylinder 110 causes the sheet 160 to abut against the other side surface of the brake disc D. At this time, the first brake is used to make the film 14 and the second brake to make the film 16 〇 to clamp the brake disk D ′ to achieve the braking effect. It is worth noting that the oil seal 13 弹性 elastically deforms when the piston 12 moves under the resistance of the oil seal 130. Then, when the brake master cylinder is released to cause the brake oil pressure to disappear, the piston 120, together with the first brake, causes the sheet 140 to move backward (to the left) due to the return spring force provided by the oil seal 130, thereby forcing the oil chamber 112. Some of the brake oil flows into the brake master cylinder', which in turn causes the first brake to cause the sheet 140 and the second brake to cause the sheet 160 to no longer grip the brake disc d. Here, the first brake car 140 and the second brake will cause the film 16 to be separated from the brake disc D by the rotation of the 1335964 of the brake disc d. As described above, since the first brake shoe 140 is abutted against the piston 120 by the bolt 150, the first brake 140 and the piston 120 are used even in the absence of the brake hydraulic pressure. There will be no gaps between them. Therefore, when the floating brake caliper 100 is in a vibrating environment, the first brake pedal 140 does not knock with the piston 120 (or even the brake disc D), thereby effectively suppressing noise generated by vibration. Although the present invention has been disclosed in its preferred embodiments, it is not intended to limit the invention, and may be modified and modified without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
