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.
