How Trailer Tie Rods Work
The trailer tie rod is specially used to adjust the spacing of the trailer suspension. The working principle is that when adjusting the tie arm, since the main function of the tie arm is pulling force, in order to ensure the changing trend of the fixed tie rod, it should be extended after the adjustment. Then shorten it to the standard state. When adjusting the pull arm, you should also pay attention to the change of the left and right gaps to ensure that the pull arm is in a pulled state.
A semi-trailer tie rod structure. The upper end of the tie rod is fixedly connected to the fixed panel on the semitrailer. The lower end of the tie rod is fixedly connected to the ear plate on the semitrailer. The number of tie rods is two, and the two tie rods are on the same vertical plane. Set up in parallel, add a fixed joint through the thickness direction of the fixed panel at the position corresponding to the tie rod, set the fixed joint coaxially with the tie rod, both sides of the fixed joint are fixedly connected to the fixed panel, add a locking nut, and the tie rod The upper end is provided with an external thread, and the upper end of the pull rod passes through the fixed joint to form a locking fit with the locking nut. It can effectively reduce the bending moment at the bottom of the fixed panel and improve the equivalent stiffness of the fixed panel structure. In particular, it can effectively reduce the impact on the fixed panel during starting and braking processes. The fixed panel is not in direct contact with the tie rod, which can effectively reduce the fatigue impact of vehicle operation vibration on the tie rod, greatly reduce the risk of tie rod breakage, and improve the stability of the entire vehicle operation.
When the semi-trailer is driving with a load and turning, the multi-axle torque is too large, which will cause the positioning tie rod to bend and deform, the nylon bushing in the lifting lug to break, and the length to change. When driving normally, the bridges lose parallelism, and the tires on each bridge are out of alignment. The tires are excessively worn, which increases driving resistance and wastes fuel. If the turning torque is too large, this product will take effect and the positioning tie rod of the inner ring of the turn will be shortened by force, forming a wide outer ring and narrow inner ring between the bridges, and the tire will follow the turn, reducing the lateral friction between the tire and the road surface. Driving resistance, after driving straight, the nail-piercing pull rod returns to its normal positioning state under the action of the spring.
In order to overcome the deformation and breakage of the bushing due to excessive turning torque on the original vehicle tie rod, and extend the service life of the bushing, alloy steel is selected, and the bushing and lifting lugs have a sliding fit. The service life can be replaced once every 2 years.
