The inner side of the inner ring fixing ring 105 is sealingly connected with a pipeline 1051.

[0027] The friction disc 1024 is provided with an inner ring hole 1023 in the middle, the two friction discs 1024 are provided with a heat dissipation ring 106 fixedly connected with the brake disc 102 in the middle, the heat dissipation ring 106 is provided with a plurality of guide vanes 1061 fixedly connected in the middle, the guide vanes 1061 are of an arc-shaped structure, the arc-shaped structure is more conducive to the flow of wind, and the outer ring of the heat dissipation ring 106 is not in contact with the inner ring of the friction disc 1024, so that when the cold wind blows from the middle of the heat dissipation ring 106 to the friction disc 1024, the heat can be more easily taken away.

[0028] The brake disc 102 is provided with a hub fixing hole 1021 and a limiting hole 1022 at the other end, the hub fixing hole 1021 and the limiting hole 1022 are alternately arranged, the limiting hole 1022 is threadedly connected with a fixing bolt 101, and the limiting hole 1022 is fixedly connected with a double-circuit rotating device 2 on one side. The double-circuit rotating device 2 is threadedly connected with the fixing bolt 101, and the above design can fix the double-circuit rotating device 2 and fix the brake disc 102 and the hub.

[0029] The pipeline 1051 on one side of the inner ring fixing ring 105 passes through the inner ring hole 1023 and the limiting hole 1022 and is sealingly connected with the double-circuit rotating device 2. The double-circuit rotating device 2 is sealingly connected with the liquid inlet pipe 4 and the liquid outlet pipe 7 on one side.

The outer ring fixing ring 103 and the inner ring fixing ring 105 are semicircular structures. Two outer ring fixing rings 103 and inner ring fixing rings 105 can form a complete circle. The inner ring fixing ring 105 and the outer ring fixing ring 103 are made of steel. The outer ring fixing ring 103 and the inner ring fixing ring 105 are arranged in a semicircular shape for easy installation. The gap in the two friction discs 1024 can be directly installed, and it is also convenient for observation and maintenance in the later period. The outer sealing ring 104 and the inner sealing ring 107 are made of rubber material. The sealing effect of rubber is good, and the cooling liquid is not easy to leak during long-term use. The double-circuit rotating device 2 used in the utility model mainly functions to make the air-cooled liquid-cooled brake disc body 1 rotate, so that the water in the storage tank 6 can flow into the air-cooled liquid-cooled brake disc body 1 through the double-circuit rotating device 2 to provide cooling liquid for cooling, which is the existing structure and will not be described here.

[0032] When the vehicle needs to be braked temporarily during operation, the air is blown to the friction disc 1024 through the heat dissipation ring 106 to cool and dissipate heat of the friction disc 1024, meeting the normal use; if long-time braking is required, the infusion pump 5 is started in advance to transport the cooling liquid in the storage tank 6 to the double-circuit rotating device 2 through the infusion pump 5, and then the double-circuit rotating device 2 transports the cooling liquid to the gap between the two friction discs 1024 through the pipeline 1051. After circulating in the interior one round through the flow guide block 1025, the cooling liquid is transported to the double-circuit rotating device 2 through the pipeline 1051, and then the double-circuit rotating device 2 transports the cooling liquid to the storage tank 6. In this way, the high temperature generated by the long-time friction of the brake caliper on the friction disc 1024 can be dealt with, the cooling effect is better, and the air-cooled liquid-cooled brake disc body 1 can be used for a long time.
