Automobile wheels include hub bolt holders, drainage spiral blades and rims. The structural points of the hub bolt holders and rims are provided with drainage spiral blades to drain air to the outside of the hub, but the drainage spiral blades can drive the air flow when the wheel rotates, and the air flow forms wind, but the guide spiral blades guide the air flow from the inside of the car to the...
1. In order to maximize safety and reliability, it is recommended that you always check the hub bearings no matter how old the car is-pay attention to whether the bearings have early warning signs of wear: including any friction noise during rotation or abnormal deceleration of the suspension combination wheel when turning.For rear-wheel drive vehicles, it is recommended that the front wheel hub b...
In fact, whether it is a family car or an operating vehicle, how often a car tire needs to be filled is not judged based on time, but based on the tire pressure value of the car tire to determine whether the tire needs to be inflated.It is not that the tire must be inflated once a month or two. What the owner needs to do is to check the air pressure value of the tire within a certain period of tim...
Three-piece aluminum alloy wheels are tightened by a central member and two outer rings and screws. In order to reduce quality, many three-piece aluminum wheels use forgings. Three-piece aluminum wheels use forgings. The three-piece structure provides manufacturers with greater flexibility for small batch manufacturing. For high-speed vehicles, high-temperature tire bursting and reduced braking ef...
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...
Aluminum alloy wheels have the advantages of fuel saving, good heat dissipation, extended engine life, good roundness, and durability. They have been widely used in the automotive industry. Aluminum alloy wheels have a beautiful appearance and have become a fashion in many countries and regions. The surface coating process of aluminum alloy wheel hub includes: first pretreatment of the wheel hub, ...
The selection of wheels, how to choose the best one?Many people will transform the car at will in order to change the performance of the car. The transformation of the car requires professional knowledge. For the wheel rim, we cannot arbitrarily increase its diameter. 1. Don't blindly increase the wheels.Some people increase the wheels to improve the performance of the car. When the outer diameter...
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 ...
The aluminum alloy wheels forged in our country use 6061 grade aluminum alloy (LD30). Compared with traditional steel wheels, they have the advantages of light weight, beautiful appearance, and good heat dissipation performance. However, due to the limitations of 6061 material, under the existing commonly used forging methods, its good mechanical properties can only reach tensile strength of 350Mp...
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...
