Wear-resistant elastic wheel rims forged tyres for tram

In response to customer requirements, Kingrail designed a steel for wear-resistant elastic wheel rims and a heat treatment method and production method thereof. 0.25~0.60%, Mn 0.70~1.20%, P≤0.015%, S≤0.015%, Mo≤0.35%, V≤0.20%, the rest are Fe and inevitable impurity elements; The relative C content of steel is higher than that of LG61 tires, which is equivalent to CL70 wheels. Compared with LG61 tires, the strength and hardness are improved, which is equivalent to the strength of CL70, while maintaining the good plastic toughness of LG61, especially the stability of wheel impact toughness. has significantly improved

To address the shortcomings of the original tire exit method. The kingrail adopts an internal combustion engine wheel hoop exit device. The device includes a tire bracket, the bracket includes a chassis and a support plate, the chassis and the support plate are connected by a connecting rod, the support plate is a circular structure, and 3-4 locking clamps are distributed on the support plate, and the lock The free end of the clamping fixture is hook-shaped, and the other end of the clamping fixture is connected to the axle seat fixed on the support plate through a shaft. The withdrawing device of the utility model adopts the method of relative displacement by hydraulic pressure, which can greatly reduce the labor intensity of the operator and improve the work efficiency at the same time.

Kingrail adopts a new locomotive wheel rim replacement device. One end of the swivel set with the vertical axis is installed in the installation hole of the horizontally set platform, and the lower shoulder and the corresponding annular groove on the platform are equipped with evenly distributed supports. The ball, the swivel sleeve is fitted with a circular tray supported on the upper shoulder, the bracket is L-shaped, and is installed on the circumference of the platform with the swivel sleeve axis as the center through the long holes and bolts perpendicular to the swivel sleeve axis. Corresponding to the position of the tire, two layers of gas delivery pipes are installed, the nozzles are evenly distributed on the gas delivery pipe, and the diameter of the circumference where the nozzle is located is 200~300mm larger than the outer diameter of the tire. The device has the advantages of simple structure, convenient operation, safety and low energy consumption.
