Fuwa traction pin90

Function of Fuwa traction pin 90

The Fuwa traction pin 90 is a key component in the connection between a tractor and a semi-trailer. Its main function is to connect the semi-trailer to the tractor, ensuring a stable and secure connection during transportation. The hollow design of the pin 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, ensuring the safe and efficient operation of the vehicle combination.

Material of Fuwa traction pin 90

The Fuwa traction pin 90 is typically crafted from high-strength materials to withstand the heavy loads and demanding conditions encountered in vehicle operation. Common materials include:

• Alloy Steel: For heavy-duty 90 traction pins, materials like 8630 alloy steel may be used. This type of steel offers excellent mechanical properties, including high tensile strength and good wear resistance. After heat treatment, it can achieve a hardness of HB 302-363, making it suitable for withstanding the high stresses and strains during vehicle operation.

• Special Alloy Steels: In some cases, traction pins may be made from specialized alloy steels, such as AISI 4320H, which are used for various welding structures. After heat treatment, this material can achieve a hardness of HB 380-420, meeting specific performance requirements.
