Four wheel dynamic balancing is achieved by correcting the weight balance of the wheels (tires+hub), so that the vehicle tires are always in concentric motion. Four wheel alignment and dynamic balance are important factors in ensuring vehicle safety, stability, and durability. However, many friends are not clear about the difference between dynamic balance and four-wheel alignment, and many have been deceived into doing four-wheel alignment. In order to avoid or eliminate this phenomenon that has already occurred, it is necessary to adjust the balance of each edge of the wheel by increasing the counterweight in dynamic conditions. This correction process is commonly known as dynamic balance.
First, let's understand the four-wheel alignment. Four wheel alignment is not a maintenance item, but a repair item, which means that it is only necessary to do four-wheel alignment when the car has problems. Its function is to maintain stable straight-line driving and lightweight steering of the car, while also reducing the wear and tear on the tires and steering system during driving. Generally speaking, when a car is driving normally, the following situations require four-wheel alignment. The first scenario is when the tire experiences abnormal wear such as uneven wear; The second scenario is when the car is driving normally and there is steering wheel deviation, shaking, inaccurate steering, or the steering wheel cannot automatically return to its original position after turning; The third scenario involves damage to the chassis and suspension, especially the steering system, after an accident occurs.
Due to the relative positioning between the four wheels, suspension, steering mechanism, and front and rear axles of the vehicle, this position follows the standard values set by the manufacturer. However, as the mileage accumulates and tires wear out, these fixed data will be altered, and even small changes can lead to significant driving risks. Four wheel alignment is achieved by adjusting the geometric angles of the tires, steering, suspension, and other components to ensure a tight fit between the tires and the ground.
After replacing or repairing the shock absorber, steering and other systems, four-wheel alignment must be performed to adjust the precision of the angles between the various components of the chassis system. If the four-wheel alignment is not accurate, it will excessively wear out the vehicle chassis system. If the vehicle frequently gets on the curb (especially on the front wheels) and frequently crosses speed bumps quickly, it is also necessary to pay attention. If the vehicle experiences deviation, decreased steering accuracy, misaligned steering wheel, severe tire gnawing, and other phenomena, while ensuring normal "dynamic balance", it may also be caused by inaccurate positioning angles. Therefore, four-wheel alignment needs to be considered.
Next, let's take a look at the wheel dynamic balance correction. The function of dynamic balance is actually to correct the configuration balance of the wheels, so that the tires are always in concentric motion. Simply put, due to differences in the production of tires and wheels, the mass distribution of different parts of the wheels may be balanced, resulting in dynamic imbalance when the car is running at high speeds. Dynamic balance is to eliminate this situation. Generally speaking, when the tire and tire have been removed, it is necessary to perform dynamic balancing, which means that whether it is tire repair, tire replacement, or wheel hub replacement, dynamic balancing is required.
Dynamic balancing is aimed at the wheels. When the tires are installed on the wheel hub, there will always be errors in the manufacturing accuracy of the tires and wheel hub, resulting in the weight of each point on the wheel not being exactly the same. If a wheel is sometimes heavy and sometimes light, it will shake when rotating. Just like a fan, if all the wings are the same, it can rotate smoothly without shaking. If one of the wings is replaced with a different one, lighter or heavier than the others, it will cause the fan to rotate unstably and shake severely. The same principle applies to the rotation of tires. If a point is lighter or heavier than the same area on the opposite side, it will rotate unstably.
How to solve the problem of wheel dynamic balance? Wheel dynamic balance detection is to solve the problem of uneven mass distribution. By adding a balance block, if a point is 10 grams lighter than the same place on the opposite side, then adding a 10 gram balance block at that point can achieve the same weight. Dynamic balancing is actually finding lighter points on the wheels and adding balance weights to them. The wheels have a slight imbalance, which is generally not noticeable when driving. If the difference is below 10 grams, it is generally not noticeable. If it is above 10 grams, there will be noticeable shaking at high speeds. The wheel is a whole composed of two parts, the tire and the hub, but due to processing technology and other reasons (such as the presence of valves), the mass distribution of each part of the wheel cannot be very uniform. When the car wheels rotate at high speed, they will form a dynamic imbalance state, causing the vehicle to shake and the steering wheel to vibrate during driving.
