[0010] Figure 1 This is a cross-sectional schematic diagram of an embodiment of the present utility model;

[0011] Reference numerals: rim-1, polyurethane adhesive layer-2, cylindrical body-3, rubber layer-4. Detailed Implementation

[0012] like Figure 1 As shown, a shock-absorbing structure for a mining polyurethane solid tire includes a rim 1 and a polyurethane adhesive layer 2. The polyurethane adhesive layer 2 is embedded on the outer surface of the rim 1 by an adhesive process to form a solid tire. A circular cylinder 3 is bonded to the outside of the polyurethane adhesive layer 1, and a rubber layer 4 is vulcanized and cast onto the circular cylinder 3.

[0013] To improve the bonding strength between the cylindrical body and the polyurethane adhesive layer and rubber layer on both sides, the cylindrical body is a sheet metal cylinder with roughened surfaces on both sides.

[0014] To ensure the shock absorption effect of the tire, the thickness ratio of the polyurethane adhesive layer to the rubber layer is 3:1.

[0015] To ensure the load-bearing capacity of the tire, the thickness of the sheet metal cylinder is 1mm-1.5mm.

[0016] To ensure a strong bond between the polyurethane adhesive layer and the cylindrical body, the polyurethane adhesive layer and the cylindrical body are bonded together using PU adhesive.

[0017] In the tire casting process of this utility model, after the polyurethane layer of the tire is cast to 3 / 4 of the existing tire thickness, the surface is treated, and then the roughened iron cylindrical body on both sides is bonded to the polyurethane tire. On the other side of the iron cylindrical body, the rubber layer is vulcanized and wrapped around the iron cylindrical body, which ensures the outer diameter of the tire, the tire's weight (load capacity), and the better shock absorption performance of the rubber layer, thus meeting the needs of customers.
