drawbar

The truck drawbar can be divided into 3 structural forms, namely, one end rotating and one end fixed structure, two ends fixed structure and two ends rotating structure. In order to have good interchangeability, both ends of the tow bar adopt F-type standard hook-tail structure. The tail of the fixed end 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 can not only improve the ability of the vehicle to pass through the curve, but also have the function of automatically resetting the coupler; the tail of the rotating end is a global The surface structure can be flexibly rotated 360 degrees in the rotating tail frame together with the rotating sleeve sleeved on the outside.

The truck drawbar can be divided into 3 structural forms, namely, one end rotating and one end fixed structure, two ends fixed structure and two ends rotating structure. In order to have good interchangeability, both ends of the tow bar adopt F-type standard hook-tail structure. The tail of the fixed end 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 can not only improve the ability of the vehicle to pass through the curve, but also have the function of automatically resetting the coupler; the tail of the rotating end is a global The surface structure can be flexibly rotated 360 degrees in the rotating tail frame together with the rotating sleeve sleeved on the outside.
In order to ensure the casting manufacturability of the structure, process holes are opened at the symmetrical positions on the upper and lower sides of the drawbar, and the structure of the transition of a large arc in the upper section and the transition of a small arc in the lower section is adopted, which greatly avoids casting defects such as shrinkage holes.
In order to prolong the service life of the drawbar, the drawbar has grooves in the contact part with the joist on the car body to weld the wear plate.
