How to do car dynamic balance

1. Put the tire on the dynamic balancer.Fix it with a buckle. If the tire has an old balance block, you need to put down the old balance block first. Measure the distance from the machine to the tire rim. Enter the corresponding value on the machine. Use a caliper to measure the width of the steel ring. After obtaining the numerical value, enter the data into the machine.

2. Install the wheel assembly to move the balance on the wheel balance testing machine, slowly rotate the wheel, clamp the wheel with the wheel shaft, and rotate the self-friendly mouth. Measure the width and diameter of the rim with a ring caliper. Pull out the caliper and measure the distance between the inner edge of the wheel and the wheel balancer. The measurement parameter loses the dashboard.

3. Install the wheel assembly to be dynamically balanced on the wheel balance testing machine, slowly rotate the wheel, clamp the wheel with the axle end fixture, and rotate the wheel from the friend's mouth. Input the measurement item and measure the rim width and rim diameter with a ring caliper.Pull out the brake caliper and measure the distance between the inner edge of the wheel and the wheel balancer.

4. After removing the tire, clean the tire. The dirt in the rim or the stone on the tire should be completely cleaned. If it is an old tire, there may be an old balance block on the tire, and it should also be removed.

5. When doing the dynamic balance test, you must go to a professional store and a store with professional technicians. You must pay attention to the tires of your car when you use it. Tires are the only part in the car that touches the ground. Tires are related to the handling and driving stability of the car. Tires are rubber products, which will age if used for a long time and need to be replaced regularly.

What is car dynamic balance

Car wheel dynamic balance refers to the operation carried out to make the wheel rotate without vibration and additional force caused by unbalanced mass.Even if the wheels are statically balanced, they may be unbalanced. At the opposite radial position of the axle 0 and O, the same mass W still does not leave the rotation axis of the wheel, so the wheel is statically balanced.

What is the dynamic balance of a car? The dynamic balance of a car refers to the balance between the four wheels of the vehicle during driving. A good dynamic balance system can improve the stability and safety of the vehicle and extend the service life of the tire.

The dynamic balance of a car usually refers to the balance between the four wheels of a car during driving. Because the quality of the tires will not be particularly uniform after being repaired, the balance block will be used to adjust the balance of the tires.

car Introduction to dynamic balance knowledge

is a necessary adjustment tool for cars. Dynamic balance refers to the operation of determining the position and size of the imbalance generated by the rotation of the rotor and eliminating it. The imbalance will cause the lateral vibration of the rotor and cause the rotor to be subjected to unnecessary dynamic load, which is not conducive to the normal operation of the rotor. Dynamic balance tests will be done when the vehicle is assembled from the factory.

The meaning of dynamic balance Dynamic balance is a research content of rotor dynamics, which refers to determining the rotor rotation.The operation of eliminating the position and size of the unbalanced quantity (centrifugal force and centrifugal force pair, see relative motion) generated during motion.

The dynamic balance of a car is the balance between the wheels when the vehicle is driving. It is usually called installing balance blocks. The wheels of a car are a whole composed of tires and hubs. However, due to manufacturing reasons, the mass distribution of the whole parts cannot be very uniform.

Wheel balance can be divided into dynamic balance and static balance. Dynamic imbalance will cause the wheels to shake, causing wavy wear of the tires. Static imbalance will cause bumps and jumps, which often leads to flat points in the tires.

Four-wheel positioning is required. The wheels of a car are a whole composed of tires and hubs. However, due to manufacturing reasons, the mass distribution of the whole parts cannot be very uniform.When the wheels of the car rotate at high speed, they will form a state of unbalance, causing the wheel to shake and the steering wheel to vibrate while the vehicle is driving.

The centrifugal force in the opposite direction produces a force pair between the two, trying to tilt the wheel and make the wheel in a state of unbalance. Only when the sum W# of the same mass is placed in the reverse direction of mass W and W, the resulting force pair is countered to the resulting force pair and the resulting force pair, and the wheel can be balanced.
