The coupler coupler body of a railway vehicle is a device that connects different vehicles and provides buffering and power transmission. The coupler coupler body conforming to the AAR (American Association of Railroads) standard has high strength and reliability.

First of all, the coupler body is made of high-quality alloy steel material, which undergoes strict heat treatment and machining to provide excellent strength and durability. It can withstand the impact and tension between trains, ensure a firm connection, not easy to fall off, and provide stable force transmission and buffering between vehicles.

Secondly, the coupler body structure design meets the geometric parameters required by the AAR standard to ensure precise connection between adjacent vehicles. It includes a large ring interface to connect the coupler and lifting lug and ensure the reliability of the connection. Additionally, the coupler body includes a groove or land for receiving and mounting the bumper.

Finally, the coupler body attachment usually consists of screws and pins to ensure a secure connection. These connections meet the requirements of AAR standards and ensure that they will not loosen or break during train operation.

All in all, AAR-compliant rail car coupler bodies feature high-strength materials, accurate geometry and reliable coupling. It can stably connect railway vehicles, and provide the functions of buffering and power transmission to ensure the safety and stability of train operation.
