Coupler yoke is an important part of coupler buffer device. It is a key part to install slave plate and buffer and bear the traction force of train. The train is grouped after the railway vehicles coupled by the couplers. The coupler hook is connected with the coupler yoke through the coupler yoke pin. When the vehicle is towed by the traction force, the force transmission process is: coupler → coupler yoke pin → coupler yoke → buffer → slave plate → front slave plate seat → traction beam; When the vehicle is impacted, the transmission process of force is: coupler → coupler pin → coupler yoke → slave plate → buffer → rear slave plate seat → traction beam.
Coupler yokes could be manufactured by casting and forging. The material is Grade E steel. Forged coupler yoke is an upgraded product of cast coupler yoke, which is mainly suitable for heavy-duty trains above 70t. The forging coupler yoke is processed by die forging and tempering after welding to have better strength and service performances. The fatigue strength of forging types can be increased by 80% ~ 200% to avoid porosity and shrinkage which might occur for casting type. Through ultrasonic flaw detection and magnetic particle flaw detection, all performance indexes of coupler yokes meet the standard requirements, ensuring the vehicle transportation performance and driving safety.

FAQ:
Q1: Are you a trading company or a factory?
A: We are directly a factory and we manufacture and export railway wagons and wagon parts directly.
Q2: Chinese railway gauge is 1435mm, but our country’s is 1000mm gauge, will this be a problem for you?
A: Of course not, we are able to design railway wagon bogies of different gauges like 1435mm, 1000mm, 1067mm, 1520mm or other required railway gauges.
Q3: Why should I choose you, compared with your competitors?
A: Tieke Railway was transformed from wagons factory belong to Chinese Railway in 2016 and the company have over 10 years’ experiences in manufacturing railway wagons and bogies; Now as Tieke Railway is a private company and adopt modern market management strategies, our services are flexible and more considerate and our cost is more controllable.
Q4: What should I provide to get a quotation from you?
A: You could send your inquiry with detail drawings, product photos, detail technical parameters or requirement description. A complete requirement input is very important for us to provide an accurate quotation to you.
