Symptoms When the fuel tanker brakes, the direction of travel is skewed. During emergency braking, the direction is sharp or the vehicle flicks.
1 Inconsistent tire pressure, pattern, or degree of wear on the left and right wheels.
2 Left and right wheel hub bearings have different elasticity and individual bearings are damaged.
3 The brake shoe friction linings of the left and right wheels are of different materials or are of different ages.
4 The contact area and position of the brake shoe of the left and right wheels and the brake drum are not the same or the brake clearance is not equal.
5 The technical conditions of the left and right wheel cylinders are different, resulting in unequal time or tension.
6 The thickness and diameter of the brake drums on the left and right wheels, the degree of deformation during operation and the roughness of the working surface are not the same.
7 The unilateral brake line is concave, blocked or leaking; the unilateral brake pipe or wheel cylinder has air resistance.
8 The unilateral brake shoe is too tight or corroded with the support pin.
9 side suspension spring broken or elastic too low.
10 side shock absorber oil leakage or failure. The front wheel positioning misalignment; dedicated transmission mechanism loose; frame, axle bending in the horizontal plane, the wheelbase on both sides of the wheelbase ranging; sense load proportional valve failure. Summary: The basic cause of brake runaway is the brake force of the left and right wheels. Some parts that do not belong to the brake system have a poor technical condition that not only affects the normal running deviation of the vehicle, but also affects the braking. The deviation.
Diagnosis and exclusion
If the refueling truck has deviation during normal driving, first perform an appearance inspection: check whether the tire pressure, pattern, and degree of wear of the left and right wheels are the same; check whether each shock absorber leaks or fails; check whether the suspension spring is broken or elastic Support the wheel, rotate it by hand and push and pull the wheel tire in the axial direction. If the wheel on one side feels loose or too tight, adjust the pre-tightening degree of the bearing; if there is a card issuing or abnormal sound when rotating the wheel, check the wheel hub bearing. Whether it is damaged or destroyed. After the road test is performed on the car, if the car is deviated to one side, it is a bad brake on the other side. First, the wheel brake is deflated. If no brake fluid is ejected, Explain that the brake pipe of this wheel is blocked and should be replaced. If there is air in the released brake fluid, it means that air is mixed in the brake pipe of this wheel and should be discharged. Observe the gap of this wheel brake. If the brake clearance is too large, Description Brake shoes friction plate wear or brake self-adjustment device failure, should be replaced.

Displacement phenomenon of mobile refueling vehicles
When it comes to the problem of deviation of mobile refueling vehicles, people who may have worked in this area have a certain understanding of it. Over the years, my company has accumulated a lot of work experience in this industry. Here we will introduce this to you. The causes of the phenomenon and commonly used solutions:
