The wheel of a car is composed of tires and hubs as a whole. However, due to manufacturing reasons, the mass distribution of the parts of the whole cannot be very uniform. When the car wheel rotates at high speed, it will form a dynamic unbalance state, resulting in the vehicle in the running wheel jitter, steering wheel vibration phenomenon. In order to avoid this phenomenon or eliminate this phenomenon has occurred, it is necessary to make the wheel in the dynamic situation by increasing the counterweight method, so that the wheel correction of the edge of the balance. This process of correction is known as dynamic balance.

Dynamic balance

Dynamic balance refers to the asymmetric weight distribution produced by the forces of the tire as it rotates, usually at a higher speed. In the tire factory, the wheel is tested by a tire and wheel balancing machine, which is accelerated to speeds of 300 RPM or higher and measures force imbalance as the tire rotates sensors.

On the inside and outside wheels of the plane, these forces are decomposed into static and force couple values compared to the unbalanced tolerance (which is the maximum allowable manufacturing limit). If the tyre is not selected, it is likely to wobble and perform poorly. At a tire retail store, check the tire/wheel assembly on the screen-on balancer, which determines the unbalance and Angle.

Tire balance block action

Because the driving mode of the car is generally the front drive, the front wheel load is greater than the rear wheel, the car driving a certain mileage, different parts of the tire in fatigue and wear degree will be different. Therefore, it is necessary to carry out tire transposition according to the mileage or road conditions;

When the wheel turns, the asymmetric mass may cause a jump or wobble, which may cause interference with the ride, usually longitudinal and lateral vibrations. It can also cause swings in a steering wheel or throughout the vehicle.

Because of the imbalance, the ride is not comfortable. The vehicle suspension can excite the wheel speed when under unbalanced force to a point where the rotation frequency is equal to the resonant frequency of the suspension.

The uneven quality of the tire will affect the stability of the rotation of the object, the higher the speed, the greater the vibration. Therefore, the role of the tire balance block is to reduce the mass gap of the wheel as far as possible, in order to achieve a relatively balanced state.

Due to the complex road situation, any situation on the road may have an impact on the tire and the ring, such as collision platform, high-speed through the pothole road, easy to cause deformation of the ring, so it is necessary to do the tire dynamic balance at the same time.

What's the effect of a falling tire counterweight

According to the above tire balance block, we can know that it is very important to ensure the tire balance, which not only helps to prolong the service life of the tire and the normal play of vehicle performance, but also contributes to the safety of the driver's life. Unbalanced tire movement will lead to irregular tire wear and unnecessary wear of vehicle suspension system, and unbalanced tires on the road will also cause vehicle turbulence, resulting in driving fatigue.

Therefore, the tire balance block off the tire balance more or less will have an impact, it depends on the owner of the car when driving do not feel out.

The error value of general tire dynamic balance is 5g-10g. The smallest balancer is 5g. If a piece of balancer is missing, a tyre with at least 5g must be unbalanced.

The balance is not good when the car runs to a certain speed will shiver and is damaged tire bearings and then affect the suspension body, it is best to hurry up with a new to prevent future problems.
