[0042] It should be noted that the cooling tube body 33 can be constructed of aluminum, which not only allows the coolant to flow inside the cooling tube body 33 to absorb heat, but also allows the good thermal conductivity of aluminum to further dissipate heat, effectively reducing the heat transferred to the suspension rod system 2.

[0043] In some embodiments, the cooling tube body 33 is suitable for being bonded and connected to the base plate 31 .

[0044] Specifically, by connecting the cooling tube body 33 to the base plate 31, the cooling tube body 33 can be fixed, that is, the flow path of the coolant can be restricted to ensure the smooth flow of the coolant in the cooling tube body 33, thereby improving the reliability of absorbing heat by the coolant. At the same time, it can also avoid the movement of the cooling tube body 33 and the weakening of the heat absorption effect.

[0049] Specifically, the first cooling part 311 , the intermediate connecting part 312 and the second cooling part 313 can all be used to absorb and diffuse heat. By connecting the first cooling part 311 and the second cooling part 313 through the intermediate connecting part 312 , heat can be transferred between the first cooling part 311 and the second cooling part 313 .

[0050] In such Figure 2-Figure 3 In the illustrated embodiment, the first cooling portion 311 is disposed above the bottom plate 31, and the first cooling portion 311 can be used to absorb the heat above the brake disc 1. The second cooling portion 313 is disposed below the bottom plate 31, and the second cooling portion 313 can be used to absorb the heat below the brake disc 1. At the same time, the intermediate connecting portion 312 is disposed in the middle position of the bottom plate 31, and the intermediate connecting portion 312 can be used to absorb the heat in the middle of the brake disc 1. The first cooling portion 311 and the second cooling portion 313 are connected by the intermediate connecting portion 312, so that heat can be transferred between the first cooling portion 311 and the second cooling portion 313, thereby improving the reliability of absorbing heat by the bottom plate 31.

[0051] Among them, the middle connecting part 312 is constructed as an arc segment, and the first cooling part 311 and the second cooling part 313 form an intermediate avoidance area 3121 on the inner side of the middle connecting part 312 and an outer avoidance area 3122 on the outer side of the middle connecting part 312, the middle avoidance area 3121 is used to avoid the suspension rod system 2, and the outer avoidance area 3122 is used to avoid the brake caliper of the brake disc 1.

[0052] Specifically, the middle connecting portion 312 is constructed as an arc segment to make the edge smooth to avoid scratching the user and reduce the difficulty of processing. A middle avoidance area 3121 and an outer avoidance area 3122 are respectively formed on the inner and outer sides of the middle connecting portion 312, wherein the middle avoidance area 3121 is used to avoid the suspension rod system 2, that is, to avoid the installation area of ​​the suspension rod system 2 to ensure that the suspension rod system 2 can be installed smoothly, and the outer avoidance area is used to avoid the brake caliper of the brake disc 1, that is, to avoid the brake caliper from being unable to be installed due to the setting of the middle connecting portion 312, thereby causing the vehicle to be unable to brake.

[0053] And, it should be noted that if Figure 2-Figure 3 As shown, the inner and outer sides of the first cooling portion 311 and the second cooling portion 313 are both constructed in an arc shape to make their edges smooth and not easy to scratch the user, and the first cooling portion 311 and the second cooling portion 313 are both bent toward the middle avoidance area 3121 to avoid the installation area of ​​the suspension rod system 2.

[0054] In some embodiments, a cooling channel 34 is formed in the first cooling portion 311 and / or the second cooling portion 313 .

[0055] That is, a cooling channel 34 may be formed in the first cooling part 311 , or in the second cooling part 313 , or in both the first cooling part 311 and the second cooling part 313 , so as to absorb heat by the flow of coolant in the cooling channel 34 .

[0056] Specifically, the bottom plate 31 includes a first cooling portion 311 and a second cooling portion 313, both of which can absorb and diffuse heat, and the first cooling portion 311 and the second cooling portion 313 are connected by the intermediate connecting portion 312, so that heat can also be transferred between the first cooling portion 311 and the second cooling portion 313. Figure 3 As shown, a cooling channel 34 is formed in the first cooling portion 311 , which allows the coolant to flow in the first cooling portion 311 to absorb heat, thereby reducing the heat transferred to the suspension link system 2 and extending the service life of the suspension link system 2 .

[0057] And, it should be noted that if Figure 3As shown, the cooling channel 34 is set in the first cooling part 311, and the first cooling part 311 and the second cooling part 313 are connected through the intermediate connecting part 312. The cooling channel 34 can be used to absorb the heat of the first cooling part 311 and the second cooling part 313 at the same time, which can reduce the setting length of the cooling channel 34 and reduce the setting cost.

[0058] In some embodiments, the cooling channel 34 includes a plurality of sub-channels 341 , the plurality of sub-channels 341 are bent and connected in sequence, and at least two sub-channels 341 are distributed in parallel and spaced apart.

[0059] Specifically, by setting up the cooling channel 34, the coolant can flow inside it to absorb heat. The cooling channel 34 forms a plurality of sub-channels 341, that is, the coolant can flow in the plurality of sub-channels 341 to absorb heat. The plurality of sub-channels 341 are bent and connected in sequence, so that the coolant can flow in the plurality of sub-channels 341 in sequence to absorb heat. At the same time, the setting length of the cooling channel 34 can be increased to enhance the heat absorption effect. In addition, at least two sub-channels 341 can be distributed in parallel and spaced apart, so that the heat at multiple positions in the first cooling part 311 can be absorbed simultaneously through the plurality of sub-channels 341 to effectively reduce the heat transferred to the suspension link system 2.

[0060] In such Figure 3 In the illustrated embodiment, four sub-channels 341 are provided in the cooling channel 34, and the four sub-channels 341 are bent and connected in sequence, so that the coolant can flow in the four sub-channels 341 in sequence to absorb heat, and the setting length of the cooling channel 34 can be increased to enhance the effect of absorbing heat, and the four sub-channels 341 are spaced apart and distributed from each other, so that the four sub-channels 341 can be used to absorb heat from multiple positions in the first cooling part 311 at the same time.

[0061] It should be noted that the number of sub-channels 341 is not limited to that described in this embodiment, and can be flexibly arranged according to specific needs and space size.

[0062] In some embodiments, the protective cover 3 is provided with a liquid inlet 35 and a liquid outlet 36 which are in communication with the cooling channel 34 , and the liquid inlet 35 and the liquid outlet 36 are both provided at the same side edge of the protective cover 3 .

[0063] Specifically, the liquid inlet 35 is used to allow the coolant to enter the cooling channel 34, and the liquid outlet 36 is used to allow the coolant in the cooling channel 34 to flow out. That is, the coolant can flow in the cooling channel 34 through the liquid inlet 35 and the liquid outlet 36 to absorb heat, and the liquid inlet 35 and the liquid outlet 36 are arranged on the same side of the protective cover 3, which is convenient for daily operation and maintenance of the liquid inlet 35 and the liquid outlet 36. In actual use, there is no need to maintain the liquid inlet 35 and the liquid outlet 36 separately from two positions, which is convenient for operation and saves time. In addition, the liquid inlet 35 and the liquid outlet 36 are arranged at the edge of the protective cover 3 to further facilitate the operation and maintenance of the liquid inlet 35 and the liquid outlet 36.

[0064] It should be noted that the cooling channel 34 is connected to the external cooling pipeline, that is, the liquid inlet 35 and the liquid outlet 36 are respectively connected to the external cooling pipeline to achieve the communication between the cooling channel 34 and the external cooling pipeline, so that the coolant can enter the cooling channel 34 from the external cooling channel 34 through the liquid inlet 35, and then return to the external cooling pipeline from the cooling channel 34 through the liquid outlet 36, thereby realizing the circulation of the coolant, improving the reliability of heat absorption, and, as Figure 2-Figure 3 As shown, the liquid inlet 35 can be set at the end of the sub-channel 341 located at the bottom, and the liquid outlet 36 can be set at the end of the sub-channel 341 located at the top. The upper sub-channel 341 is closer to the external space, has a better heat dissipation effect, and has a lower temperature than the lower sub-channel 341. By setting the liquid inlet 35 at the bottom, the coolant can first flow to the lower sub-channel 341 and then flow to the upper sub-channel 341, so as to enhance the effect of absorbing heat.

[0065] In some embodiments, the brake disc assembly 100 also includes a connecting bracket 4, and the liquid inlet 35 and the liquid outlet 36 are respectively connected to a liquid inlet pipeline 41 and a liquid outlet pipeline 42, and the liquid inlet pipeline 41 and the liquid outlet pipeline 42 are suitable for being connected to the cantilever middle section of the suspension rod system 2 through the connecting bracket 4.

[0066] Specifically, the liquid inlet 35 is connected to the liquid inlet pipeline 41, so that the coolant in the external cooling pipeline can flow from the liquid inlet pipeline 41 through the liquid inlet 35 into the cooling channel 34 to absorb heat. At the same time, the liquid outlet 36 is connected to the liquid outlet pipeline 42, so that the coolant in the cooling channel 34 can enter the liquid outlet pipeline 42 from the liquid outlet 36 and then enter the external cooling pipeline, thereby realizing the circulation of the coolant and improving the effect of absorbing heat. The liquid inlet pipeline 41 and the liquid outlet pipeline 42 are connected to the middle section of the cantilever of the suspension rod system 2 through the connecting bracket 4, and the liquid inlet pipeline 41 and the liquid outlet pipeline 42 can be fixed by the connecting bracket 4 to prevent them from moving or shaking and affecting other components, thereby improving the safety of the vehicle.

[0067] Also, it should be noted that a certain length of the liquid inlet pipe 41 and the liquid outlet pipe 42 can be reserved at both ends of the connecting bracket 4 to ensure the normal bounce of the suspension, and to ensure that the suspension will not pull the liquid inlet pipe 41 and the liquid outlet pipe 42 when bouncing, thereby ensuring the smooth flow of the coolant in the cooling channel 34.
