What is a heavy wheel? Understand the production material of the support wheel -- the support wheel

First, the concept and use of heavy wheels

The support wheel is a special steel cast on the locomotive wheel, which is mainly used to support the traction, braking and center of gravity balance of the train. This type of wheel is mounted on the rear axle of the locomotive - the support wheel

It plays an important role in supporting, cushioning and carrying train loads during train operation.

Second, the production material of the heavy wheel

The production material of the heavy wheel is wear-resistant cast steel, which has high toughness and high wear resistance, and can withstand the heavy load of high-speed trains and run for a long time without failure. The heavy casting wheel is often used to blow out the gas powder furnace, which melts the cast steel at high temperature and then pours it into shape. The usual use of heavy wheel materials for 2 categories, one is the AAR M201 standard of M2 wear-resistant cast steel, the other is China's domestic provisions of QK class wear-resistant cast steel.

Three, the characteristics of the heavy wheel and production standards

The weight of the heavy wheel is large, the diameter is generally between 1.2-1.5 meters, and it has high rigidity and toughness. The production standards of the heavy wheel are mainly international standards, American standards and Chinese national standards, etc

The support wheel is made by casting method, with good mechanical properties and wear resistance, to ensure that the train has better running stability and safety reliability in high-speed and long distance operation.

Iv. Summary

As one of the important parts of the train, the support wheel plays a very important role. It is made of cast steel with high wear resistance and corrosion resistance, which meets the requirements of national and international standards, and has passed strict quality inspection. In the wheel manufacturing industry has a pivotal position. -- Support wheel
