Product Description：
The semi-trailer fifth wheel (also called "saddle" or "fifth wheel") is a key component that connects the tractor (truck head) and the semi-trailer. It is responsible for transmitting traction, braking force, and supporting the weight of the front of the semi-trailer, and is an important part of ensuring the safe driving of the vehicle.
Functions of the towing seat:
1. Connect the tractor and the semi-trailer:
The locking mechanism of the towing seat firmly connects the tractor and the semi-trailer.
2. Transmit traction and braking force:
The towing seat transmits the power of the tractor to the semi-trailer and transmits the braking signal at the same time.
3. Support the weight of the front of the semi-trailer:
Carry the vertical load of the front of the semi-trailer to ensure stable driving of the vehicle.
4. Provide flexibility:
Allow the semi-trailer to swing moderately in the horizontal and vertical directions to adapt to turns and road undulations.
