A drawbar suitable for vehicle towing, which includes three parts: a left drawbar connector, a connecting rod, and a right drawbar connector, which are connected and assembled by the above three parts; the drawbar connector is composed of a lock hook, a sliding lock card, Composed of lock pin and lock rod. The drawbar has a simple structure, can be disassembled, is easy to assemble, and is easy to carry. Compared with the use of existing wire ropes to tow vehicles, the drawbar is easy to connect during use and is a hard-connected tow, which can ensure towing safety.

Processing Steps
Truck drawbar water glass casting processing process flow:
① Casting
② Drill center holes in the cylindrical part and the corresponding ring part
③ Rough turning of cylindrical part
④ Finish turning cylindrical part
⑤ The tape is wrapped to protect the thread, and the inner ring surface is milled and the outer ring surface is milled.
⑥ Cut off the chuck
⑦ Verification

Structural Features
Truck drawbars can be divided into three structural forms, namely a structure with one end rotating and one fixed, a structure with both ends fixed, and a structure with both ends rotating. In order to have good interchangeability, both ends of the drawbar adopt F-type standard hook tail structure. The fixed end tail adopts a spherical structure, and a cylindrical adjustment shoulder with automatic centering function is added to the side of the tail end, so that the drawbar not only improves the vehicle's ability to pass curves but also has the function of automatically resetting the coupler; the rotating end tail is global It has a surface structure and can be flexibly rotated 360 degrees in the rotating tail frame together with the rotating sleeve on the outside.
In order to ensure the casting process of the structure, process holes are opened at symmetrical positions on the upper and lower sides of the drawbar, and a structure with a large arc transition in the upper section and a small arc transition in the lower section is adopted, which greatly avoids casting defects such as shrinkage cavities.
In order to extend the service life of the drawbar, the drawbar has grooves in the contact area with the joists on the car body for welding wear plates.
