Zero-offset rim - indicates the mounting hole fixing surface of therim, which is located on the centerline of the rim. (for SUV models and some BMW cars) Positive offset rim - indicates the distance between the joint surface of the rim and the center of the rim, which is the direction to the outside. (for front-wheel drive and some rear-wheel drive models) Negatively offset rim - in...
In the wheel industry, there are two main types of wheels: 3 piece forged andcasting. There are many advantages to each type as well as disadvantages. The main difference betweenthem is the manufacturing processes used to create them. In the forging process, 3 piece wheels begin as high-quality T6-6061 aluminum alloy billets. The billets are then subjected to intense pressure to form the...
Forging is the process of shaping metal, and is a common practice in a range of manufacturing industries. There are various types of forging, and these are often distinguished by the temperature at which it is conducted. The 3 independent classifications are cold, warm and hot, with the most popular types of metal including iron and steel almost universally forged hot. The process has many advanta...
In many unexpected times, there will be unexpected situations in the finishedrim, which will make the finished defective. At this time, we need to repair the wheels. Most of the wheels on the market are electroplated, so the maintenance of thechromed wheels and the precautions for the maintenance of the wheels are easy to share for you. When repairing arim, the first thing to do is to determi...
The rim et value means the offset value, which represents the deviation distance between the rim mounting surface and the center line of the rim. The wheel rim et value can be divided into positive and negative offset distance and zero offset distance. When the wheel rim et value is larger in the positive direction, it means that therim mounting surface is inward. The dist...
In life, tires are a very important part of the operation of the car, so where do you need to repair them when there is a problem or damage to the wheel rim of the tire?In fact, this is relatively simple. Usually, you can go to a special repair shop or the 4s shop of the car for a comprehensive overhaul. Before performing repairs, a comprehensive inspection must be carried out to clarify wher...
When our vehicles need to replace tires, in most cases they replace tires of the same specifications, but I don't know if everyone has ever thought about whether it is feasible if we replace tires of other specifications without replacing the wheels?The answer is yes, as long as you refer to the wheel tire comparison table to select the tires that can be installed. Because the use of tires of othe...
In the 1990s, in order to meet the needs of modern warfare, the lightweight of weapon systems has become the trend of the development of weapons and equipment in various countries around the world. How to reduce the weight of structural parts designed according to the strength index is the key.As an important part of the wheel, it is an important part of how to reduce weight. The weapon systems us...
During the driving process, car owners will be more concerned about the paint scratches on the car, but have they ever paid attention to the scratches on the wheels?How can I repair the wheel rim if it is scratched? The specific methods for repairing the wheel rim are: 1. Check for scratches, and carefully check whether the scratches extend to the inside of the wheelrim. If not, you only...
As we all know, wheels are an important part of automobiles.At present, aluminum alloy wheels are a commonly used automobile wheels.Compared with traditional wheels, aluminum alloy wheels have certain advantages.Therefore, automotive steel experts will introduce the advantages of aluminum alloy wheels. 1.Fuel saving For wheels of the same size, aluminum alloy wheels are 2kg lighter than steel whee...
The et value of the wheel rim is also called the et offset value, and the et value is the offset value, which is the offset.In fact, it refers to the degree of deviation between the rim installation interface and the centerline of the rim. If the et value is greater and becomes a negative value, then it proves that the rim installed on the body will deviate from the outside. So in other words, dif...
The closed forging process of the outer ring of automobile wheel rim includes cutting: the blank is made by sawing process, heating: the blank is heated to 1100~1400℃, upsetting: the blank is upsetting on the upsetting equipment to obtain a drum-shaped blank, pre-forging: The drum-shaped blank is made of pre-forged parts through the pre-forged die, precision forging: The pre-forged parts are ...
When driving in normal times, you may encounter fever in the wheels of the car. Many people may think that the car is damaged or caused by some other reason.This is a very simple question, so don't worry too much. The reason for its heat may be that the tire rubs against the ground for a long time and then generates heat that will be transmitted to it, and then it will cause its temperature to ris...
Many car owners like to drive faster and feel very irritating. Even on uneven roads, they don't speed up. However, this behavior can be very damaging to the wheels of the car.Especially for explosion-proof tires with a low flatness ratio, not only is the tire wall thin, but it is also very hard. When this kind of tire is subjected to a strong impact, the force will be directly transmitted to ...
After decades of development, China's automobile industry has become an important industry in the national economy. With the progress of technology and the improvement of various performance indicators of automobiles, governments of various countries have become more and more stringent requirements for energy conservation and environmental protection. Therefore, automobile lightweight has become t...
