After the vehicle has been driving for a period of time, it is always found that there is some slight deviation in the direction. Many driver friends do not really care about what problems the vehicle will cause to the safety of the vehicle. When the test is stopped, the computer will measure the weight of the weight that needs to be added to the inside and outside of the rim, install the outside first, turn the tire, and tap the weight according to the prompt.
After the vehicle has been driving for a period of time, it is always found that there is some slight deviation in the direction. Many driver friends do not really care about what problems the vehicle will cause to the safety of the vehicle. Long-term deviation will bring harm to the tires. In severe cases, the danger of punctures will occur. In fact, a large part of the vehicle's deviation is caused by minor changes in the tires caused by inadvertent bumping in the daily driving process. In this issue, the editors checked the correctness of the off-tracking tires and controlled the tire's deviation through balancing.
What is dynamic balance?
The wheel of a car is a whole made up of tires and wheels. However, due to manufacturing reasons, the mass distribution of the entire parts cannot be very uniform. When the car wheel rotates at a high speed, a dynamic unbalanced state will be formed, causing the wheel to shake and the steering wheel to vibrate when the vehicle is moving. In order to avoid this phenomenon or to eliminate the phenomenon that has occurred, it is necessary to make the wheels correct the balance of the edge portions by adding weights in a dynamic situation. The process of this correction is what people often call balancing.
What we have to say today is the process of correcting the balance of the tires after the tires have been damaged for a long period of time. Attentive car owners will find that there are one or more small lead blocks of different sizes on the wheel hub edge of the car. Compared with all kinds of beautiful wheels, these small lead blocks seem to be somewhat incompatible. However, it is these small and small lead blocks that play a very important role in the stability of the car at high speeds.
Tyres should be checked periodically for dynamic balance and checked with a dynamic balance tester. Tire balance is divided into two kinds of dynamic balance and static balance. Dynamic imbalance will cause the wheels to sway, causing the tires to wear wavy; static imbalance will produce bumps and bouncing, often causing flat spots in the tire. Therefore, the regular detection of balance not only can extend the life of the tire, but also can improve the stability of the car when driving, and avoid the traffic accident caused by the tire swinging, beating, and loss of control at high speeds.
Tire replacement process
Since it is the replacement of tires, we will first talk about the tire removal process. The tyre tyre changer is used here. What I want to say here is the role of the grilled tire machine in the abortion process. First, the technician releases the gas from the tire, and the technician then manually removes the edge of the tire-to-hub joint, but the disassembly is a preparatory work for the tire-blaster.
Afterwards, the technician must start the machine to separate the tire from the hub. If this process is manually operated, it will take a lot of time to complete. Therefore, the use of the machine is a good assistant for the technician to save working time.
Finally, the technician will place the processed tires in a horizontal position and use the machine's dialing function to separate the tire completely from the hub. After the dismantling is completed, we can see how the inner wall of the hub, which is rarely seen at ordinary times, looks like .
After the tires are disassembled, the technician will install the tires selected by the owner on the wheels. Now the tires are generally without liners, so the disassembly and installation also saves a lot of unnecessary trouble.
During the installation process, the technician needs to install the tire back to the hub along the reserved groove in the hub. After the installation is complete, the technician will need to inflate the tire. In the process of inflating, technicians need to continuously press the tires to correct the joint between the tires and the hub, so as to achieve the effect of tight seams. Only in this way can the tires not leak or be inflated.
Balanced operation process
The front said that the tire disassembly and installation process, we will introduce the following is a balanced operation process. The operation of this process is relatively simple and quick. However, technicians are also more rigorous about the operation process and results, because this is related to whether or not the vehicle has a safety hazard in the future.
It takes four steps to make a balancing act. First, attach the wheel to the balancing instrument and select the size of the fixture. Pull out the ruler on the balancer, measure, and enter the first controller.
The second step is to take out the bending rule and measure the rim width, which is also input on the second controller.
The third step is to enter the rim diameter on the controller and press STRAR to start.
When the test is stopped, the computer will measure the weight of the weight that needs to be added to the inside and outside of the rim, install the outside first, turn the tire, and tap the weight according to the prompt.
Balancing is only for a single tire. The purpose is to make the tire not deflect itself when it is turning. Dynamic balance as long as the tire removed, on the dynamic balance machine, turn, look at the value displayed by the machine.
Having said so much of the operation process, it is nothing more than wanting more friends of the owner to know how to repair the tire if there is a phenomenon of deviation, and to avoid the danger during driving. Regularly checking whether the tire is out of focus is the key that must be paid attention to in everyday cars.
