SINOTRUK traction seat WG9130939100 for SEMI trailer

Description

What is SINOTRUK 90 series traction seat WG9130939100?

The traction seat WG9130939100, due to its shape, can also be named as a saddle seat. It is a connecting device between semi-trailer trucks and semi-trailers. It not only plays the role of towing semi-trailers and bearing the load of semi-trailers, but also can withstand the motion conditions such as starting, accelerating, decelerating, steering, braking of the tractor, as well as the impact when connecting the semi-trailer. Through the locking mechanism, it is connected with the semi-trailer traction pin to transmit traction force and braking force.

The structural features of the traction seat WG9130939100:

The traction seat is mainly composed of a saddle plate, a locking hook, a pin block, an insurance lock and a handle control assembly. The saddle plate is the main part, and other components are installed on it. The locking hook and the pin block are controlled through the handle control assembly to achieve locking and separation with the traction pin, and the insurance lock prevents accidental disengagement of the pin.

The material of the traction seat WG9130939100:

1. High-strength steel. Application areas: saddle plate (main load-bearing plate), base frame and other main load-bearing components.

Material characteristics: Commonly used Q345B, Q690 and other low-alloy high-strength steels, with yield strength reaching over 345MPa, high tensile strength, capable of withstanding the vertical load of semi-trailers (usually up to several tons to several tens of tons) and the impact force during towing. It has good anti-fatigue performance, can adapt to long-term bumpy conditions, and reduces the risk of deformation or fracture.

2. Cast steel. Application areas: some base frames and supporting structures of the traction seat, complex-shaped components.

Material characteristics: such as ZG270 – 500 cast steel, with good casting performance, capable of forming complex structures, and having balanced strength and toughness, suitable for withstanding alternating loads. The disadvantage is that it is heavy, and some lightweight designs of the traction seat will reduce the application of cast steel.

The material design of the traction seat is a balance of “strength, wear resistance, and corrosion resistance”: the main body uses high-strength steel to ensure load-bearing, the key friction parts use alloy copper or high-molecular materials to reduce friction, and surface treatment improves weather resistance. When choosing, attention should be paid to the material grade and surface treatment process according to the vehicle load, usage conditions (such as road / engineering, climate conditions), to ensure safety and lifespan.

When using and maintaining the WG9130939100 traction seat, it is necessary to regularly check the wear conditions of its various components, especially the reliability of the locking mechanism, to ensure the safe and stable connection between the traction seat and the semi-trailer coupling pin. At the same time, operations should be carried out in accordance with the vehicle’s operation manual and relevant specifications, correctly connecting and disassembling the tractor and the semi-trailer to extend the service life of the traction seat and ensure driving safety.

How about the package of the traction seat WG9130939100?

ZK will pack according to the quantity requested by the customer. Normally, because the traction seat WG9130939100 is very heavy in weight and has an irregular shape, we will pack it in the form of a pallet. ZK spare truck has 20 years of production and sales experience. Whether it is the quality of heavy truck parts, transportation, or after-sales service, we can provide the strongest guarantee. At the same time, we can also offer more heavy truck parts of Chinese brands, such as SINOTRUCK, HOWO, SHACMAN, FAW, DONGFENG, BEIBEN, etc. Our produced engine systems, braking systems, transmissions, clutches, etc. have also led the sales in many parts of the world.
