In the past few decades, high-speed railways around the world have developed tremendously, and high-speed railway trains have become a common mode of travel. For high-speed trains, the dead weight and load of the car body are transmitted to the wheels by the axle box of the vehicle. During the operation of high-speed trains, due to reasons such as mechanical structure, processing technology, friction and poor lubrication state, the axle box will produce hot shaft faults with excessive temperature. Axle fracture caused by high temperature will lead to partial separation of vehicle with hot axle failure, and even lead to rollover accident, resulting in danger to life and property damage.
AKS offers WDJ temperature indicators, which is used on the wheel axle box of high-speed trains, with multiple temperature monitoring points, which can detect and monitor the temperature changes of equipment contacts and object surfaces in time.
