",,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, The second brake disc 42 is opposite to the first brake disc 41. Further, the brake disc D is disposed between the first brake disc 41 and the second 1327540 brake disc 42. The positioning pin 50 It is disposed in the caliper cylinder 10, the first brake squeegee 41 and the second brake squeegee 42, which can be used to position the first brake to make the sheet 41 and the second brake to position the sheet 42. As shown in FIG. 1 , FIG. 2 and FIG. 3 , both fixing pins 60 are disposed in the caliper cylinder 10 and the fixing bracket 70 to bond the caliper cylinder 10 and the fixing bracket 70 together. As shown in Fig. 3, the positioning reeds 80 are respectively abutted between the caliper cylinder φ 10 and the first brake traverse 41 and between the caliper cylinder 10 and the second brake urging sheet 42. Here, The first brake shoe 41 and the second brake shoe 42 are respectively positioned on the positioning pin 50 by the (downward) pressing force provided by the positioning spring 80. When the pump establishes a brake oil pressure, the brake oil will flow into the oil chamber 12 through the oil inlet port 11, thereby pushing the piston 20. Here, the piston 20 will move against the resistance of the oil seal 30 (to the right), and then push (abut) The first brake is connected to the piston 20 to move the sheet 41 (to the right). When the first brake comes into contact with the side surface of the brake disc D, the entire caliper cylinder 10 is reacted by the reaction force. Therefore, the movement is reversed (to the left), and thus the second brake (adjacent to the caliper cylinder 10) is pushed to move the sheet 42 (to the left) until the second brake causes the sheet 42 to interfere with the brake disc D. At the same time, the first brake 31 and the second brake can cause the blade 42 to clamp the brake disc D to achieve the braking effect. It is worth noting that the piston 20 overcomes the oil seal 30. When the resistance moves, the oil seal 30 will elastically deform. Then, when the brake master cylinder is released and the brake oil pressure disappears, the live 7 1327540 plug 20 will be reversed due to the return elastic force provided by the oil seal 30 (to the left). Moving, thus forcing some of the oil in the oil chamber 12 to flow to the crucible In the master cylinder of the vehicle, the first brakes 41 and the second brakes are used to cause the sheet 42 to no longer grip the brake disc D. Here, the first brakes 41 and the second brakes 42 It will also be separated from the brake disc D by the rotation of the disc D. However, since the second brake is used, the sheet 42 is only positioned on the positioning pin 50 by the positioning reed 80 (or, the second brake is used to order) The piece 42 is adjacent to the inner wall of the caliper cylinder 10 by the positioning pin 50 and the positioning reed 80. Therefore, in the case where the brakeless oil pressure is established, the second brake is used to make the piece 42 in the caliper cylinder 1 There is a gap between the 内 (the inner wall) and the brake disc D. Therefore, when the floating brake caliper 1 is in a vibrating environment, the second brake squeegee 42 will be associated with the caliper cylinder 10 (the inner wall) and the brake Disk D is knocked and noise is generated. 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.
