Heavy Duty Railway Couplings

Product Introduction:

Coupling is an indispensable core transmission component for railway locomotives and rolling stock, used to connect various rotating parts in the drive system. It adopts flexible or rigid connection forms to transmit torque stably, effectively cushioning vibration and mechanical impact during operation. As a key power connecting part for rail transit equipment, the coupling ensures safe and reliable torque transmission. It smoothly transfers traction power from the driving motor to the wheel set, supporting normal running and stable braking of the whole train, and guarantees the safe, efficient and steady operation of railway vehicles.
