Description of the invention: [Technical field to which the invention pertains] # The invention relates to a brake caliper, in particular to a brake caliper in the form of a single-piston caliper. [Prior Art] As shown in FIG. 1 and FIG. 2, it is a structural view of a disc brake applied to various vehicle wheels such as bicycles, steam locomotives, etc., and the disc brake structure 80 is mainly disposed at one of the wheel drums and the wheel 90. On the common center and the common rotating brake disc 91, the brake disc 91 is clamped by the hydraulically driven brake disc 81, and the brake disc 81 and the brake disc 91 are frictionally generated to grip the wheel 90. In the entire disc brake device, the brake shoe 81 is positioned by a caliper cylinder 82, and the caliper cylinder 82 is coupled to the hydraulic cylinder through a hydraulic pipe, and the brake oil inside the hydraulic cylinder is pushed by the brake lever, and the hydraulic pressure is utilized. The force pushes the piston 83 in the caliper cylinder 82, and then pushes the brake shoe 81 through the displacement pushed out by the piston, so that the brake shoe 81 contacts the brake disk 91 to achieve the braking effect. However, when the brake shoe 81 is worn out and the gap between the brake disc 91 and the brake disc 91 is increased, the brake is insensitive. At this time, the piston 83 and the oil seal in the caliper cylinder 82 automatically adjust the appropriate clearance, but Because of the high cost of the two caliper cylinders 82, there is a design of a single-piston caliper brake structure. Referring to FIG. 3, it is a cross-sectional view of a conventional single-piston caliper brake structure 70, which includes a ^-clamp cylinder 71. A piston 72 and a brake are provided in sequence to form a set 73 and an adjustment button 74. The brake is used to clamp the set 1294386 73 to the brake disc 91 of the wheel 90, and the adjustment button The position of 74 is located on the inner surface of the caliper cylinder 71, that is, the surface of the wheel 90. When the caliper cylinder 71 is to be adjusted, it is usually adjusted by the wheel 90 and by the hand tool. There are advantages of lower cost, but it is extremely inconvenient to make adjustments. SUMMARY OF THE INVENTION The main purpose of the brake caliper of the present invention is to provide a design in which the adjustment structure is disposed away from the wheel side, whereby the structure can be adjusted even with bare hands, which is very simple and convenient. A further object of the brake caliper of the present invention is to provide an adjustment structure having a segmented indication function. The brake caliper of the present invention is a brake caliper in the form of a single-piston caliper, which is mainly applied to a brake system of a vehicle, and is usually disposed on a brake disc of a wheel drum of a vehicle, and the brake disc can be clamped by the brake caliper. The braking force is generated by the brake disc and the brake disc to clamp the wheel to achieve the purpose of decelerating or restoring the vehicle. When the brake is not sensitive, it is necessary to adjust the brake caliper only when it is far away from The adjustment end of the wheel side can be adjusted. The detailed description and the technical content of the present invention will be described below with reference to the following drawings: [Embodiment] First, please refer to the schematic diagram of the position of the brake caliper and the wheel of the present invention as shown in FIG. 4 to FIG. 6 and the first embodiment of the present invention. Example structure decomposition 6 1294386 and structural cross-sectional view, as shown in the figure: The brake caliper 10 of the present type is mainly suitable for the type of shirt 塞卡锄shaped placed on the wheel of the vehicle wheel 90-- In the case where the card is not sensitive, how to carry out the adjustment of the early tongs is made by Ming. Specifically, the first embodiment is a first embodiment of the present invention. The second embodiment includes a caliper cylinder 11 and a caliper cylinder. The caliper cylinder has an adjustment end U1 and a==; The 111 system is located at the caliper cylinder n away from the trouser base group 12 is disposed at the actuation end 119, and between the active base group 12 and the adjustment group 13. The adjustment end 111 has a female thread portion 113, a channel 114, and a groove 115 between the plurality of shafts 114 of the female thread, and the adjustment: text = 131, - 盥哕Yang f,] includes a male threaded part, the state is the body of the knob 132, one finger

The elastic element 3381 and the steel ball 3382 are sequentially placed in the hole 3371, and the elastic element 3381 (in this embodiment, a spring) provides a force to push the steel ball 3382 to the holes. In the indicating hole 3352, when the knob 337 is turned, the steel ball 3382 will roll on the ring block 335, and one of the indicating holes 3352 will roll to the next indicating hole 3352, and when the steel ball 3382 enters the next indicating hole 3352. When there is a slight vibration and sound, it can be used to indicate the amount of rotation of the knob 337, and the segment adjustment can be achieved at the same time. In summary, when the brake is not sensitive, that is, the distance between the brake shoe group 34 and the brake disk plate 91 is increased due to the wear of the brake disk plate 91, it is necessary to adjust the brake caliper only when it is necessary to The adjustment end 311 of the wheel 90 can be adjusted. When the adjustment is performed, the rotation of the knob 337 will simultaneously link the coupling member 332, and when the coupling member 332 rotates, the pressure will be driven again. In the block 331, the pressing block 331 and the connecting member 332 are screwed together by the female screw 3311 and the male screw 3331. However, the limiting protrusion 3312 on the pressing block 331 is restricted by the limiting slot 313. Therefore, the pressing block 331 can only be displaced back and forth. Therefore, when the knob 337 is rotated, the pressing block 331 is moved back and forth. When the pressing block 331 moves forward, the braking piece is simultaneously pressed. Group 34 to the brakes 12 1294386 two dust: between the brake car group 34 and the brake disc plate 91 ~ people, 5 sad, like 'so-to' can restore the sensitivity of the brakes.
