J320(U) rail tyres for locomotive 915mm of diameter DF locomotive for CK1E and TY7E

Kingrail applied A high-strength light-weight rail vehicle tire and a production process thereof are used, and relate to the technical field of alloy preparation. The tire includes an outer tire, and a middle part of the inner surface of the side wall of the outer tire is integrally connected and fixed with a clamping seat, and the clamping seat includes A clamping table that is coaxial with the outer tire and a retaining ring that is integrally connected and fixed on the outside of the bottom surface of the clamping table. The end face of the clamping table is evenly distributed with a number of threaded through holes; the bottom end surface of the outer tire is integrally connected and fixed with a tread ring. It is an annular surface that completely overlaps with the bottom surface of the outer tire, the inner side of the annular surface is bent vertically outwards to form an arc-shaped tread extending downwards and outwards, and the outer edge of the annular surface is bent vertically outwards to form the bottom. The outer arc surface whose end coincides with the outer edge of the arc-shaped tread; the tread of the tire of the present invention is made into a 5-degree inclined surface, which can reduce the quality of the wheelset, facilitate the passage of the curve, and make the tread wear more uniform. The center of gravity of the vehicle reduces the mass of the wheelset and improves the flexibility of the track wheel to enter the track.Transfer the tire and tire heater to the preset position; hoist the new tire into the tire heater; step 4. Use the crane to hoist the new tire to the rim of the wheel to be installed; Press the rim in the horizontal direction; Step 5. After the tire is cooled, remove the pressing tool and the tire heater to complete the installation of the new tire. By adopting the above method, the disassembly of the traction motor components and the repeated lifting and overturning of the axle can be avoided, and the replacement efficiency of the locomotive wheel hub can be improved.

The tires of KINGRAIL are easy to transport, because they are a kind of pressure plate packaging of wheel tires, which includes a tire outer cylinder and at least three sets of fasteners. Outside the wheel rim, the outer cylinder of the rim includes several rim placement layers; each group of fasteners has the same structure and specification, and the fasteners include two spacers, two long double-ended screws and four nuts, The two spacers are respectively arranged on the upper end and the lower end of the outer cylinder of the tire. There are two through holes on the spacer block. The screw rod is set close to the inner circle of the outer cylinder of the tire, and the other double-headed screw is set close to the outer circle of the outer cylinder of the tire. The pressing plate type packaging of the wheel rim proposed by the utility model has the advantages of simple structure, convenient processing and manufacturing, and convenience for the transportation and storage of the wheel rim.
