The modern word that tow bar belongs to refers to the indispensable accessories in many kinds of mechanical devices. It is a traction coupling device used between railway vehicles, but it is different from the coupler. It is a fixed connection device between the car bodies. It only needs to be disassembled in the plant section and does not need to be disassembled in the line operation. Follow the editor of Drawbar water edge to see what its structural features are!
Truck tow bars can be divided into three types of structures, 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 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 tow bar has the function of automatically resetting the coupler in addition to improving the vehicle's ability to pass through the curve; 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, the symmetrical positions of the upper and lower sides of the drawbar are opened with process holes, and the structure of the upper section large arc transition and the lower section small arc transition is adopted, which greatly avoids casting defects such as shrinkage.
In order to prolong the service life of the traction rod, the traction rod has a groove in the contact part of the joist on the car body to weld the wear plate.
The above is the introduction of Drawbar water edge to the structural characteristics of the tow bar, you can learn more about it.
