How to prevent semi trailers from eating tires? How to solve the problem of trailer eating tires

>1. Always check whether the U-bolt is fastened in place, pay attention to the maintenance of the tie rod, especially when the new trailer pulls goods for the first time or runs 1000 kilometers, it must check the U-bolt and tie rod.

2. Not inflating according to the air pressure standard is also one of the main reasons for abnormal tire wear, low air pressure, tire bending inward, resulting in "bridge effect", tire edge serious wear; The air pressure is high, and the wear of the middle of the tire cover is accelerated.

3. Pay attention to the maintenance of tires and regularly transpose tires, which can make tire wear more uniform and effectively prolong the life of tires.

4. The driver's bad driving habits are also one of the main reasons for abnormal tire wear, such as frequent emergency braking, sharp turning, etc., which will cause abnormal tire wear. Minimizing emergency braking, sharp turns will reduce tire damage.

Let's take a look at the main reasons for tires to eat tires.

1. Front wheel ** to the wheel) to eat tires:

The straight-going positioning adjustment is not in place, and the tires are not in the straight-going position when the steering wheel returns and the steering machine returns to the zero position. The toe-in adjustment is not in place, the toe value of the radial tire is plus or minus 0mm, and the bias tire is plus or minus 3mm.

2. Rear wheels (drive wheels) eat tires

Due to the accumulation of various tolerances, the wheelbase on both sides of the frame is unequal.

3. Common reasons for front and rear tires:

The quality of the tire or the steel rim itself causes the tire to be seriously elliptical, and the tire is in contact with the ground when it rolls, and the force is uneven, which accelerates wear.

Ideally, there is only rolling friction between the tire and the ground, but due to the quality of the tire or the steel ring itself, or the loosening of the fastening nut and leaf spring riding bolts, etc., the tire cannot roll forward in a straight line, but there is a left-right swing phenomenon, which causes the tire to have sliding friction with the ground and accelerate wear.

1. Always check whether the U-shaped bolt of the semi-trailer is fastened in place, and pay attention to the maintenance of the tie rod.

2. The tires are inflated according to the air pressure standard; If the air pressure is low, the tire bends inward, creating a bridge effect, and the tire edge is severely worn; If the air pressure is high, the wear of the middle of the tire face accelerates.

3. Pay attention to the maintenance of tires and often carry out tire rotation regularly.

4. The driver should develop good driving habits and avoid emergency braking, sharp turning, etc., abnormal operations such as emergency braking and sharp turning will cause abnormal wear and tear of tires, so it is necessary to minimize the operation of emergency braking, sharp turning and other tires that are easy to wear, which can reduce tire damage and make the tire life longer.

5. The load should not be too heavy. Excessive cargo will increase the load and pressure of the tire, resulting in increased friction between the tire and the ground, and accelerating the semi-trailer to eat the tire.

A semi-trailer is a trailer with the axle behind the vehicle's center of gravity and a coupling device that transmits horizontal and vertical forces to the tractor when the vehicle is evenly loaded. Semi-trailers are generally three-axle semi-trailers, and their types are divided into 11-meter warehouse semi-trailers, 13-meter warehouse columns, low-bed semi-trailers and other types.

Semi-trailer is a kind of heavy-duty transport vehicle connected with the head of the semi-trailer through the traction pin, compared with the "monocoque" car, the semi-trailer is more able to improve the comprehensive economic benefits of road transport, the semi-trailer transport is relative to the monomer car transport, the transport efficiency can be increased by 30-50%, and the fuel consumption is reduced by 20-30%.

Reasons why tires eat tires:

1. The front wheel steering wheel eats tires: the straight-going positioning adjustment is not in place, and the tires are not in the straight-going position when the steering wheel returns and the steering machine returns to the zero position; The toe-in adjustment is not in place, the toe-in value of radial tires is about plus or minus 0mm, and the bias tire is about plus or minus 3mm.

2. The common reason for the front and rear wheels to eat tires: it may be the quality problem of the tire or the steel rim itself, which causes the tire to be seriously elliptical, and the tire is unevenly in contact with the ground when rolling, which will accelerate the wear of the tire.

3. There is only rolling friction between the tire and the ground, but due to the installation of the tire or the steel ring itself, the tightening nut and the loose leaf spring riding bolt cause the tire to not roll forward in a straight line and smoothly, and there will be a left and right swing phenomenon, which increases the rolling friction between the tire and the ground, and also produces sliding friction to accelerate the wear of the tire.

This is a problem with the wheelbase of the rear axle of the trailer, and you can go to the trailer repair site to adjust the wheelbase.

Eating tires is a normal phenomenon, and the car should be checked more carefully if it has this problem. If the tire pressure is not normal due to the air pressure standard, it is one of the main reasons for eating the tire, the air pressure is low, the tire is bent inward, resulting in a "bridge effect", and the tire edge is seriously worn; The air pressure is high, and the wear of the middle of the tire cover is accelerated. The unreasonable loading process of distribution will also cause "eating tires", especially for card friends who transport bulk cargo, and must pay attention to the force balance of tires when distributing multiple goods together.

There is another point that the vast majority of cardholders have ignorened, that is, suspension, because of the phenomenon of eating tires caused by suspension, but there are many examples of frequent tire changes, so when purchasing a trailer, we must pay attention to whether the suspension of the trailer is an anti-tire design. The suspension system of the Lieniu trailer is anti-tire, and the suspension can effectively prevent tyres if the tie rod is horizontal.
