Considering the whole weight and the heat dissipation effect of solid tyre, the shunting device 5 is preferably set to 3-5 fan-shaped box structures fixedly connected to the wheel hub 1. If the distribution of the flow dividing devices 5 is too few, the heat dissipation effect is not good enough; if the flow dividing device 5 is arranged too much, the overall weight of the solid tire is increased. In this embodiment, four flow dividing devices 5 in a fan-shaped box structure are uniformly arranged on the hub 1, and the flow dividing devices 5 are fixedly connected between the rim 3 and the spoke 4. When the shunting device 5 adopts a box structure, the diameter of the rim 3 is not less than 10 inches, otherwise the shunting device 5 occupies more space in the hub 1, thereby influencing the installation of the solid tire on a vehicle; on the contrary, in order to facilitate the smooth installation of the solid tire on the vehicle without reducing the overall structure of the flow dividing device 5 in a matching manner, the overall heat dissipation effect of the flow dividing device 5 on the solid tire is affected.

The open end 552 of the collector 55 near the spoke 4 is in communication with one end of the first and second flow-dividing members 54, 56, respectively, near the spoke 4. So configured, the heat sink 8 on the solid tire carcass 2 and the flow dividing device 5 on the wheel hub 1 form a closed channel through the first connecting hole 31, the second connecting hole 32 and the third connecting hole 33 of the wheel rim 3.
Before the solid tire works, the heat-dissipating medium 9 is injected into the solid tire through the injection port 51. As shown in fig. 2, the arrows indicate the flow direction of the heat medium 9. When the solid tyre works, the heat dissipation medium 9 in the solid tyre casing 2 absorbs the heat generated by the solid tyre casing 2 during the operation in the heat dissipation device 8. As the solid tire rolls, the heat dissipation medium 9 flows from the heat dissipation device 8 to the flow dividing device 5 of the wheel hub 1; meanwhile, the outside air enters the cavity area 57 inside the flow dividing device 5 through the heat dissipation extension slots 52 and the heat dissipation holes 53 arranged on the outer side of the box body of the flow dividing device 5 in the axial direction, and the outside air flows in the cavity area 57, so that the heat dissipation medium 9 which absorbs heat and is heated in the flow dividing device 5 is cooled; the heat-dissipating medium 9 having been cooled down flows back to the heat-dissipating device 8 of the solid tire case 2. Thus, the heat dissipation medium 9 circularly flows in the heat dissipation device 8 of the solid tire carcass 2 and the flow dividing device 5 of the hub 1, so that the purpose of quickly dissipating heat of the solid tire is achieved.
The heat-radiating medium 9 is preferably water, and secondly preferably wax, and in the present embodiment, the heat-radiating medium 9 is water. In order to further increase the heat dissipation effect of the heat dissipation medium 9, at least two flow dividers of the flow divider 5, which are connected to and extend through the radial tube 83 of the heat dissipation device 8 in a matching manner, are arranged in the axial direction and the circumferential direction. In the present embodiment, as shown in fig. 2, the first branch pipe 54 connected to and penetrating the first radial pipe 831 in the heat sink 8 is composed of first branch pipes 541 and 542 in the axial direction and two first branch pipes (not shown in the figure) in the circumferential direction; the second flow divider 56, which is connected to and penetrates the third radial tube 833 of the heat sink 8 in a matching manner, is composed of second flow divider branches 561, 562 in the axial direction and two second flow divider branches (not shown in the figure) in the circumferential direction. In this way, the contact area of the flow dividing member in the flow dividing device 5 with the outside air can be increased, thereby accelerating the cooling speed of the heat dissipating medium 9 flowing through the flow dividing device 5.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
