Railway Coupler Yoke Alloy Steel Casting

The Railway Coupler Yoke is the core force-transmitting and connecting component of a railway coupler system, usually installed between the coupler head and the draft gear on freight wagon underframes. It is mainly made of high-quality alloy cast steel or quenched-tempered alloy steel, featuring high structural strength, excellent impact toughness and stable force transmission performance. It withstands huge longitudinal traction, braking forces and coupling impact loads during train operation, enduring repeated cyclic stresses in complex working conditions. Its performance directly affects the force transmission efficiency of the coupler system, draft gear structural stability and railway freight wagon running safety.
