Description of the Invention: [Technical Field] The present invention relates to a floating brake caliper, and more particularly to a floating brake caliper which can effectively prevent the brake oil from vaporizing due to high temperature. [Prior Art] Please refer to 1 , 2 , and 3 , a conventional floating brake card sweet 1 mainly includes a clamp cylinder 10 , a piston 20 , an oil seal 30 , a heat insulation block 35 , and a first brake . A piece (inner car to make a piece) 41, a second piece of car to make a piece (outer car to make a piece) 42, a positioning pin 50, two fixing pins 60, a fixing frame 70 and a positioning spring 80. 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 insulating block 35 is disposed in the piston 20. Here, the heat insulating block 35 is made of a material having extremely poor heat transfer characteristics (e.g., bakelite). The first brake shoe (inner brake blade) 41 is abutted against the heat insulating block 6 1335965 35, and the first brake shoe 41 is spaced apart from the piston 20. The second brake disc (the outer brake disc) 42 is abutted against the caliper cylinder 10, and the second brake disc 42 is relative to the first brake to the disc 4, and the disc D is It is disposed between the first brake shoe 41 and the second brake shoe 42. • The locating pin 50 is disposed in the caliper cylinder 10, the first brake sprocket 41, and the second brake squeegee 42. The locating pin 50 can be used to position the first brake to cause the blade 41 and the second brake to cause the blade 42. The location. • As shown in Figs. 1, 2, and 3, both fixing pins 60 are disposed in the caliper cylinder 10 and the fixing frame 70 to bond the caliper cylinder 10 and the fixing frame 70 together. As shown in Fig. 3, the positioning reeds 80 are respectively abutted between the caliper cylinder 10 and the first brake shoe 41 and between the caliper cylinder 10 and the second brake shoe 42. Here, the first brake shoe 41 and the second brake shoe 42 are respectively positioned on the positioning lock 50 by the (downward) pressing force provided by the positioning spring 80. • When a brake pump is established with the brake master cylinder, the brake oil flows into the oil chamber 12 via the inlet port 11, thus pushing the piston 20. Here, the piston 20, together with the insulating block 35, moves against the resistance of the oil seal 30 (to the right), thereby pushing (abutting against the insulating block 35) the first brake to move the sheet 41 (to the right). When the first brake shoe 41 is in contact with one side surface of the brake disc D, the entire caliper cylinder 10 is reversely moved (to the left) due to the reaction force, and thus is pushed (abuts against the caliper cylinder 10). The second brake is used to move the sheet 42 (to the left) until the second brake comes into contact with the other side surface of the 7 1335965 of the brake disc D. At this time, the first brake comes to the sheet 41 and the second brake to cause the sheet 42 to grip the brake disc D to achieve the braking effect. It is worth noting that the oil seal 30 is elastically deformed as the piston 20 moves against the resistance of the oil seal 30. Then, when the brake master cylinder is released and the brake oil pressure disappears, the piston 20 together with the heat insulating block 35 will reverse (to the left) due to the return elastic force provided by the oil seal 30, thus forcing the middle of the oil chamber 12 The brake oil flows into the brake master cylinder, which in turn causes the first brake to make the film 41 and the second brake to make the film 42 no longer clamp the brake disk D. Here, the first brake shoe 41 and the second brake shoe 42 are also separated from the brake disk D by the rotation of the brake disk D. As described above, when the floating brake caliper 1 is frequently operated, it is often accompanied by high heat generation, which is usually accumulated on the first brake shoe 41 and the second brake shoe 42. Therefore, the first brake is used to isolate the sheet 41 from the piston 20 by the heat insulating block 35, so that the first brake can be prevented from directly transferring the heat on the sheet 41 to the piston 20, thereby preventing the brake in the oil chamber 12. The oil is vaporized by the high temperature, thereby ensuring the braking effect of the floating brake caliper 1. However, since the first brake is used to position the sheet 41 on the positioning pin 50 only by the positioning spring 80, the first brake is used to block the sheet 41 in the case of no brake oil pressure build-up. There will be a gap between the 35 and the brake disc D. Therefore, when the floating brake caliper 1 is in a vibrating environment, the first brake shoe 41 will be knocked with the heat insulating block 35 and the brake disk D. Here, the insulating block 35 made of a material having extremely poor heat transfer characteristics (for example, bakelite) usually does not have a hard texture (or the heat insulating block 35 is not made of a hard metal material). Therefore, after the first brake shoe 41 and the heat insulating block 35 are struck by each other for a long period of time, the heat insulating block 35 is worn out, thereby causing the first brake to cause the blade 41 to directly contact the piston 20. At this time, the heat of the first brake to the sheet 41 is directly transmitted to the piston 20, so that the brake oil in the oil chamber 12 is vaporized due to the high temperature, which may cause the floating brake caliper 1 to fail to provide the brake effect. In view of the above, an object of the present invention is to provide a floating brake caliper which can effectively prevent the brake oil from vaporizing due to high temperature to ensure the braking effect of the brake. SUMMARY OF THE INVENTION The present invention basically employs the features detailed below in order to solve the above problems.

In still another aspect of the invention, the insulating block is disposed in the piston, and the metal block is disposed in the insulating block and protrudes from the insulating block. The above described objects, features and advantages of the present invention will become more apparent from the description of the appended claims. [Embodiment] A preferred embodiment of the present invention will be described with reference to the drawings. Referring to FIG. 4 , FIG. 5 and FIG. 6 , the floating brake caliper 1 本 of the embodiment mainly includes a caliper cylinder 110 , a piston 120 , an oil seal 130 , a heat insulation block 135 , and a metal block . Block 136, a first brake-making piece (inner car to make a piece) 141, a second brake-making piece (outer car to make a piece) 142, a positioning pin 150, two fixing pins 160, a fixing frame 170 And a positioning reed 180. The caliper cylinder 110 has an oil inlet port 111 and an oil chamber 112. The oil inlet port 111 is connected to the oil chamber 112. In addition, the oil inlet port 111 is connected to a brake master cylinder (not shown), and the brake master cylinder, the oil inlet port 111 and the oil chamber 112 each contain brake oil (not shown). As shown in Fig. 6, the piston 120 is disposed in the oil chamber 112 in a moving manner. The oil seal 130 is attached to the caliper cylinder 110 (the inner wall), and the oil seal 130 10 1335965 is sleeved on the (outer wall) of the piston 120. Here, the oil seal 13 is used to prevent oil from leaking into the caliper red body 11 from the oil to 112. The insulating block 135 is coupled to the piston 120. In the present embodiment, the heat insulating block 135 is also disposed in the piston 120. Further, the heat insulating block 135 is made of a material having extremely poor heat transfer characteristics (e.g., bakelite). The metal stop 136 is coupled to the insulating block 135 and the metal stop 136 is spaced apart from the piston 120. In the present embodiment, the metal stopper 136 is also disposed in the heat insulating block 135, and the metal block 136 protrudes from the heat insulating φ block 135. The first brake shoe (inner brake blade) 141 is abutted against the metal block 136, and the first brake shoe 141 is spaced apart from the heat insulating block I% and the piston 120. The first brake block (outer carriage) 142 is abutted against the card sweets 110 (the inner wall)' and the second brake block 142 is relative to the first brake shoe 141. Further, a car disc D is disposed between the first brake shoe 141 and the second brake shoe 142. The locating pin 150 is disposed in the caliper cylinder 11 〇, the first brake lining 141 and the second brake lining 142. The locating pin 150 can be used to position the first brake to make the 141 and the second brake to make the film. 142 location. As shown in Figs. 4, 5, and 6, the two fixing pins 16 are disposed in the caliper cylinder 110 and the fixing frame 17 to join the caliper cylinder and the fixing frame 170. As shown in Fig. 6, the positioning springs 180 are respectively abutted between the caliper cylinder 110 and the first brake lining 141 and between the caliper cylinder 11 〇 and the second 1335 965 brake lining 142. Here, the first brake shoe 141 and the second brake shoe 142 are respectively positioned on the positioning pin 150 by the (downward) pressing force provided by the positioning spring 180. When a brake cylinder pressure is established by the brake master cylinder, the brake oil flows into the oil chamber 112 via the inlet port 111, thereby pushing the piston 120. Here, the piston 120 together with the heat insulating block 135 and the metal stopper 136 will move against the resistance of the oil seal 130 (to the right), thereby pushing (abutting against the metal stopper 136) the first brake to the sheet 141 (to the right) )mobile. When the first brake coming block 141 is in contact with one side surface of the brake disc D, the entire caliper cylinder 110 is reversed (to the left) due to the reaction force, and thus pushed (abuts against the caliper cylinder) The second brake is used to move the sheet 142 (to the left) until the second brake causes the sheet 142 to abut against the other side surface of the brake disc D. At this time, the first brake slap 141 and the second brake slap the 142 to clamp the brake disc D to achieve the brake effect. It is worth noting that the oil seal 130 is elastically deformed when the piston 120 is moved by the resistance of the oil seal 130. Then, when the brake master cylinder is released and the brake oil pressure disappears, the piston 120 together with the heat insulating block 135 and the metal stopper 136 are reversed (to the left) by the return elastic force provided by the oil seal 130, thereby A portion of the brake oil in the oil chamber 112 is forced to flow into the brake master cylinder, thereby causing the first brake to cause the sheet 141 and the second brake to cause the sheet 142 to no longer grip the brake disc D. Here, the first brake 141 and the second brake 142 are also separated from the brake disc D by the rotation of the brake disc D.
如上所述，當浮動式煞車卡鉗100處於震動環境中 時，第一煞車來令片141會與金屬擋塊136及煞車碟盤D 1335965 發生敲擊。然而，由於金屬擋塊136具有高硬度，故即使 在第一煞車來令片141與金屬擋塊136經長期相互敲擊 後，金屬擋塊136也不會發生磨損，因而可使得第一煞車 來令片141仍舊保持分離於與隔熱塊135及活塞120。此 外，由於金屬擋塊136是藉由隔熱塊135而間隔於活塞 120,故第一煞車來令片141上之熱量會傳導至金屬擋塊 136，而幾乎無法傳導至活塞120。因此，油室112中之煞 車油絕對不會因高溫而發生汽化，因而可確保浮動式煞車 • 卡鉗100之煞車制動效果。 雖然本發明已以較佳實施例揭露於上，然其並非用以 限定本發明，任何熟習此項技藝者，在不脫離本發明之精 神和範圍内，當可作些許之更動與潤飾，因此本發明之保 護範圍當視後附之申請專利範圍所界定者為準。As described above, when the floating brake caliper 100 is in a vibrating environment, the first brake carriage 141 will strike with the metal stopper 136 and the brake disc D 1335965. However, since the metal stopper 136 has high hardness, even after the first brake 141 and the metal stopper 136 are struck by each other for a long period of time, the metal stopper 136 does not wear, so that the first brake can be made. The sheet 141 remains separated from the insulating block 135 and the piston 120. In addition, since the metal stopper 136 is spaced apart from the piston 120 by the heat insulating block 135, the first brake causes the heat on the sheet 141 to be conducted to the metal stopper 136, and is hardly conducted to the piston 120. Therefore, the oil in the oil chamber 112 is never vaporized by the high temperature, thereby ensuring the braking effect of the floating brake/caliper 100. 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.
