In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0025] like Figure 1-4As shown, the present embodiment provides a disc brake axle for a load-carrying semitrailer, comprising an axle body 1, wherein the axle body 1 comprises a tire mounting column 2, a cross beam 3, and a brake air chamber 31, brake calipers 21 and brake discs 22 are mounted at both ends of the cross beam 3, a cooling pipe 4 is fixedly connected to the inner wall of the brake caliper 21, and the cooling pipe 4 comprises a left return pipe 41 and a right return pipe 42, a sealed shell 1 321, a sealed shell 2 322, and a sealed shell 3 33 are fixedly mounted on the cross beam 3, a pump 30 is mounted on the sealed shell 1 321 and the sealed shell 2 322, an input end of the pump 30 is fixedly connected to the sealed shell 1 321, and an output end of the pump 30 is fixedly connected to the sealed shell 2 322, one end of the left return pipe 41 is sealed and slidably connected to the sealed shell 1 321, and the other end is sealed and slidably connected to the sealed shell 3 33 One end of the right return pipe 42 is sealed and slidably connected to the sealing shell 2 322, and the other end is sealed and slidably connected to the sealing shell 3 33, so that the left return pipe 41 and the right return pipe 42 can move synchronously with the brake caliper 21 to prevent the cooling pipe 4 from being unable to move when the brake caliper 21 brakes the brake disc 22, resulting in damage to the cooling pipe 4. An air intake assembly 5 is installed on the brake caliper 21, and the air intake assembly 5 includes an air intake duct 51, a mounting plate 52, and a capillary 53. The air intake duct 51 is fixedly connected to the brake caliper 21, and a mounting plate 52 is fixedly installed at the air outlet of the air intake duct 51. A plurality of capillary 53 are fixedly installed on the mounting plate 52. By arranging the air intake duct 51 and the capillary 53, a narrow tube effect is formed between the two, that is, the air is compressed and the pressure changes when passing through the capillary 53, thereby cooling the air.

[0026] The left return pipe 41 and the right return pipe 42 are both fixedly mounted with heat sinks 43 , so that the coolant 6 in the left return pipe 41 and the right return pipe 42 can dissipate heat when circulating.

[0027] A connecting plate 23 is fixedly mounted on the brake caliper 21 , and the air inlet duct 51 is fixedly connected to the connecting plate 23 .

[0028] A fan 54 is fixedly installed in the air inlet duct 51 to assist the air inlet duct 51 in taking in air.

[0029] The cooling pipe 4 , the sealing shell 1 321 and the sealing shell 3 33 are all injected with cooling liquid 6 .

[0030] The capillary tube 53 is loosely matched with the brake disc 22 to prevent friction between the capillary tube 53 and the brake disc 22 when the brake caliper 21 brakes the brake disc 22 .

[0031] The crossbeam 3 is fixedly mounted with two brake air chambers 31 , and the output ends of the brake air chambers 31 are connected to the brake caliper 21 .

[0032] A filter screen 7 is fixedly installed at the air inlet end of the air inlet duct 51 to prevent foreign objects from entering the air inlet duct 51 and causing blockage of the air inlet duct 51 .

[0033] The specific operation is as follows: during the driving process of the vehicle, it is necessary to brake. During the braking process, the brake caliper 21 and the brake disc 22 are clamped and rubbed, so that the driving speed of the vehicle is reduced. The brake caliper 21 is therefore heated, and the cooling pipe 4 is connected to the brake caliper 21. The pump 30 works to make the coolant 6 flow back and forth between the left return pipe 41 and the right return pipe 42. Since the cooling pipe 4 is provided with a heat sink 53, the coolant 6 releases the absorbed heat during the flow process. When the brake caliper 21 and the brake disc 22 are braked, the brake caliper 21 will move, and the left return pipe 41 and the sealing housing 321, the sealing housing 322, the sealing housing 323, the sealing housing 324, the sealing housing 325, the sealing housing 326, the sealing housing 327, the sealing housing 328, the sealing housing 329, the sealing housing 321, the sealing housing 329, the sealing housing 321, the sealing housing 328, the sealing housing 329, the sealing housing 321, the sealing housing 32 ...1, the sealing housing 322, the sealing housing 321, the sealing housing 321, the sealing housing The sealing shell three 33 is slidably and sealedly connected, and the right return pipe 42 is slidably and sealedly connected with the sealing shell two 322 and the sealing shell three 33. Therefore, when the brake caliper 21 is in action, the left return pipe 41 and the right return pipe 42 slide to prevent the cooling pipe 4 from being unable to be effectively cooled when the brake caliper 21 is braking. At the same time, as the vehicle is moving forward, air enters the air inlet duct 51 and then passes through the capillary 53. When passing through the capillary 53, the air will be compressed, thereby causing the air to be cooled. The cooled air will be blown toward the brake disc 23 through the capillary 53, causing the brake disc 23 to be cooled.
