The railway knuckle coupler is the core coupling and force-transmitting component of a railway vehicle's semi-automatic coupling system, usually installed in the coupler draft gear at the underframe end with its head exposed for vehicle docking. It is mainly made of AAR Grade C/E cast steel or quenched-tempered wear-resistant cast steel, featuring high strength, excellent impact toughness and reliable interchangeability. It withstands huge longitudinal traction, braking forces and coupling impact loads during train operation, and its performance directly affects coupling reliability, force transmission efficiency and overall running safety of railway vehicles.
