Function of Fuwa traction pin 50

The Fuwa traction pin 50 is a crucial component used to connect a semi-trailer to a tractor. Its primary function is to provide a stable and secure connection point between the two vehicles, ensuring that the semi-trailer remains firmly attached during transportation. The hollow design may serve specific purposes, such as facilitating the installation of additional components or allowing for the passage of fluids or cables, depending on the application requirements. By securely connecting the semi-trailer to the tractor, the traction pin enables the transfer of traction forces, contributing to the safe and efficient operation of the vehicle combination.

Material of Fuwa traction pin 50

The Fuwa traction pin 50 is typically crafted from high-strength materials to withstand the heavy loads and demanding conditions encountered in vehicle operation. A common material choice is clean low-alloy steel and carbon steel, which are known for their chemical stability. These materials are often cold-forged to achieve high strength and good wear resistance. Additionally, for 50# assembly-type traction pins, the pin head is usually made of 40Cr material, while the flange-mounted assembly plate is made of Q345 (or Q355) steel, the same material used for the semi-trailer's (traction plate). For welding-type traction pins, 20CrMnTi steel is commonly selected due to its good weldability. For heavy-duty 90# traction pins, materials like 8630 alloy steel or AISI 4320H may be used, offering enhanced mechanical properties and heat treatment characteristics.
