New description: [New technical field] [0001] This creation is about the disc brake system of a vehicle, especially the hollow part inside the piston located in the oil chamber to block the friction between the set and the disc. The heat generated is transferred into a technical area of brake fluid. [Prior Art] [0002] According to the common methods of driving in the life, there are disc brakes and drum brakes, all of which use the brakes to make the discs rub the discs to produce the braking effect. They are often used in automobiles and motorcycles. Bicycles, etc. The calipers of vehicles, etc., at the same time, it is common to use oil pressure to brake the brakes to make the film mostly. The oil pressure has the advantage of generating large force and uniformity, but it must be in the case of stable oil quality, but it is often caused by the brakes. The friction of the sheet generates heat, and the heat is transmitted to the hydraulic oil and the hydraulic oil tank through the back plate and the hydraulic cylinder. However, the volume of the hydraulic oil in the oil sump and the oil pipe is constant, and the volume is made due to the principle of "thermal expansion and contraction". The expansion, the risk of smashing the car, especially when driving on the downhill section, it is necessary to step on the brakes from time to time to control the speed of the downhill driving. It is more likely to let the brakes move more frequently when the brakes are used. Brake hydraulic oil boils, creating a risk of brake failure. Therefore, some manufacturers will add a heat shield to the back of the film to prevent the thermal expansion effect of the hydraulic oil. Please refer to the conventional structure 7 shown in Figure 8, which is the Taiwanese patent TW-M299127 "Bicycle disc brake The structure is improved, and a body 71 is disclosed. The side of the body 71 has a slot 72. The slot 72 is provided with a hydraulic actuating member, and the slot 72 is received by a brake clip 73. The brake clamp 73 has two opposite brake plates 731, and the two brake plates 731 are received in the slot 72 of the body 71, and utilize a pivot 10120853 (^W A0101 page 3 / total 20 pages 1012027727-0 The M438424 is pivoted, and a brake pad 732 is respectively disposed on the opposite side of the two brake plates 731, and the two brake pads 731 are disposed between the two brake pads 732. And each of the brake plates 731 is fixed on one side of each of the brake pads 732 to fix a heat insulating plate 733 having a heat insulating effect, wherein the heat insulating plate 733 is made of plastic or silicone. [New content] [00〇3 [The problem to be solved] However, the conventional structure 7 described above is provided with a heat insulating plate 733 on the back plate to block the heat insulating source. The hydraulic oil and oil groove in the oil pipe, so that the heat is concentrated to the sheet and its back plate or the brake disc to affect the braking effect, especially the heat insulating plate is made of plastic, silicone or the like, due to heat. Concentrating on the brakes to make the sheet and its back sheet 'make the heat insulation board 733 lose its strong sound at high temperature', causing the brake to be inaccurate, and at the same time the shear resistance of the heat insulation board is deteriorated, so it will tear when braking The heat insulation board causes the brake to drop the piece, which in turn creates the risk of being unable to brake. It can be said that the conventional structure 7 is a relatively unsafe structure, and there is room for improvement. (Technical means for solving the problem) Therefore, this The main purpose of the creation is to provide a heat-insulating caliper piston structure that is anti-locking or brake failure.

(Compared with the efficacy of the prior art) As can be seen from the above description, this creation can achieve the following effects compared with the prior art: 1. The creation system has a hollow zone inside the caliper piston, and the hollow zone is set to Vacuum, when the piston car oil (4) to make the back plate of the film set, it is urged to make the brake part of the film set and the disk contact friction, also because of 10120853# single number A0101 g ς ^ . u ^ 1012027727-0 M438424 The thermal insulation of the hollow zone prevents the heat generated by the film set from being transmitted to the car oil.

Side, the rebound bomb When the left blade 31 and the right blade 22 are respectively actuated by the left piston 31 and the right piston 32, the sheet 23 can be applied to the left blade 21 and the right blade 22 to give a restoring force. The left command piece 21 and the right come command piece 22 are respectively returned to the home position. 10120853#单号A01〇l Page 6 of 201012027727-0 M438424 The piston set 3 includes a left piston 31 and a right piston 32, and the left piston 31 and the right piston 32 are made of stainless steel or aluminum. The metal material is made of 'and is soldered to the left oil chamber 121 and the right oil chamber 122, and one ends of the left piston 31 and the right piston 32 respectively abut the back plates 211 and 221 provided for the sheet group 2. In addition, the left piston 31 and the right piston 32 are both concave and symmetrical with each other and the left piston 31 or the right piston 32 are respectively engaged by a large barrel 313, 323 and a small barrel 314, 324. The hollow regions 311 and 321 are formed and formed, and the hollow regions 311 and 321 are set to be vacuumed to achieve the heat-dissipating effect, so as to block the heat generated by the friction between the wafer group 2 and the disk 5 to be transferred to the brake oil 6 The left piston 31 and the right piston 32 are recessed 312 and 322, so that the corresponding hollow regions 311 and 321 are also concave, and the left piston 31 and the right piston 32 are respectively hollow. It is cylindrical, so the hollow areas 311 and 321 are also hollow cylindrical. The plurality of oil seals 4' are respectively disposed between the left piston 31, the right piston 32 and the corresponding left oil chamber 121 and the right oil chamber 122, and the oil seal 4 is actuated in the left piston 31 and the right piston 32. It has the effect of preventing the brake oil 6 from draining. 1012027727-0 Please refer to Fig. 4 and Fig. 5' to form a vehicle's clamp system by the above components. Generally, the caliper system is fixed to the vehicle body, and the disk 5 is attached to the vehicle. When the wheels are linked, the disc 5 is inserted into the recess 11 provided in the caliper, and the left and right flaps 21 and 22 are placed on the two sides of the disc 5, respectively. The back plate 211 and the right command piece 22 are the elastic force of the plate 221 which is erroneously restored to the elastic piece 23 and are respectively in contact with and abut against one ends of the left piston 31 and the right piston 32, so that the piston group 3 can be controlled to make the film set 2 holds the disc 5 or not to achieve the braking effect of the card sweet A. Generally speaking, the power source of the piston group 3 is from the pressure 101902531 of the car killing oil 6 · single number Α η ηηη page 7 / total 20 pages M438424 force 'and the brake oil 6 pressure system car oil pipe from the vehicle respect The human hand β presses the _ turn or the foot on the pedal to allow the driver to control the braking purpose of the vehicle. In the general caliper structure, usually the brake oil 6, the piston group 3, the order piece 2 and the disk 5' are generated by the friction of the group 2 and the disk 5 in the case of the brake of the vehicle. The heat will be transmitted to the brake oil 6 through the piston group 3, and the oil temperature of the brake oil 6 will rise, causing the volume of the brake oil 6 to expand, and then the car will travel as a towel, and the caliper will make the plate 2 The disc car may be stuck or stuck to prevent the vehicle from moving. The oil temperature of the brake oil 6 is also raised to a high temperature, which will also vaporize the oil 6 and cause the brakes to fail. Therefore, in the piston group 3 of the caliper of the present invention, a heat insulating structure is added, and a hollow area mi, 321 is disposed in each of the left piston 31 and the right piston 32, and the vacuum area 31 321 is set to A air to block the order. The heat generated by the friction between the sheet group 2 and the disc 5 is transmitted to the brake oil 6, which ensures that the temperature of the brake oil 6 is stabilized to prevent the jam A from being locked or the brake from malfunctioning.
