Railway Casting Parts China Wagon Coupler Dreaft Gear Device
Product overview
The coupler device is used to connect each carriages of the train, maintain a certain distance between carriages, and transfer and alleviate the longitudinal force and impact force generated during the running or shunting of the train. The HT13B coupler buffer device is mainly of a coupler, yoke pin, yoke, follower, draft gear, yoke bracket, striker, coupler carrier and check casting, etc. T
he coupler and the draft gear are designed in the frame draft sill. The yoke integrates coupler and yoke, so that thevehicle possesses the three functions of coupling, traction and buffering.
