The coupler knuckle is the core engaging and force-transmitting component of a railway knuckle coupler, usually installed inside the coupler head to enable automatic coupling and uncoupling between vehicles. It is mainly made of AAR Grade E cast steel or quenched-tempered wear-resistant cast steel, featuring high strength, excellent impact toughness and precise dimensional accuracy. It withstands huge traction, braking forces and coupling impact loads during train operation and docking, and its performance directly affects coupling reliability, force transmission efficiency and railway vehicle running safety.
