What is a car wheel shell?
Automobile wheel shell is also called wheel ring, wheel, tire bell, tire inner rim support tire round barrel, center mounted on the shaft metal parts. Wheel shell according to the diameter, width, molding methods, materials of different kinds.
According to the characteristics and needs of different models, the surface treatment process of the wheel shell will also take different ways, which can be roughly divided into two kinds of paint and electroplating.
The wheel shell on the market can be divided into two categories according to the material of steel wheel shell and gold wheel shell.
How much pressure can spinning wheels withstand? Get to know
The pressure that the spinning wheel can withstand varies depending on the diameter, material, processing accuracy and other factors, generally about thousands of cows.
First, the concept and production process of spinning wheel hub
Spinning wheel hub is a production process of vehicle wheel hub, the production process is a piece of metal plate through cooling, cutting, spinning, cold bending and other processes into the shape of the wheel hub, often used in small and medium bearing high-speed vehicles. Spinning wheels mainly have the following characteristics: light weight, high strength, good corrosion resistance, beautiful appearance, low cost.
Second, the design characteristics of spinning wheel hub
The design and material selection of spinning wheel hub are the decisive factors of its ability to withstand high pressure. The structure of spinning wheel hub is generally composed of three parts: edge, spoke and disk. Among them, the edge connects the spoke and the tire, and distributes the load capacity; The spoke connects the edge and the disc and provides support through compression; The disc connects directly to the bearing and spoke and supports the entire wheel. The focus of spinning hub design is to maximize the strength and stiffness of the hub to ensure that it can withstand large pressure while ensuring its durability.
Third, the pressure range that the spinning wheel can withstand
The pressure a spinning hub can withstand depends on a variety of factors, including the material of the hub, diameter, machining accuracy and service conditions. In general, the pressure that spinning wheels can withstand is about thousands of cows. If it exceeds the pressure it can withstand, the hub will undergo plastic deformation or even fracture, posing a threat to safety. Therefore, it is particularly important to choose the right spinning wheel hub.
For example, the 3mm thickness of aluminum alloy spinning wheel passed the test and withstood about 30 tons of pressure at 6000 RPM; The 4mm thick titanium alloy spinning hub withstood about 40 tons of pressure at 8000 RPM.
How do I remove the wheel cover?
1, fixed wheel cover can be taken in two ways. One is to use the spring to stabilize the wheel cover, the specific operation is: grip the edge of the wheel cover, pull outward with force, and then remove the center cover. If you choose to use tire screws to fix, you need to lift the tire, loosen the screws that fix the hub counterclockwise, and make sure that the removed screws are not lost, and then remove the hub.
2, remove the hub center cover is also simple and clear, the center cover also has two fixed ways. If the spring is used to fix, just hold the hubcap edge and pull it outward, and the center cover can be easily removed.
3. The disassembly method is briefly summarized as follows: grip the rim of the hubcap and pull outward to achieve disassembly. When installing, make sure the position is aligned and press hard inward. Pay special attention to the position of the air nozzle during installation. If the position is incorrect, the installation cannot be completed.
4, disassembly, you can use the disassembly hook in the vehicle tool, insert it into the hole of the wheel decoration cover, then pull down, you can easily remove the decoration cover. Be careful not to use the hex head inside the screwdriver handle to loosen or tighten the wheel bolts.
5, the design of the wheel cover is mainly for aesthetic considerations, and it can be removed only by a gentle pull. The outer cover is fixed on the steel ring through the circlip, and the fixing screw of the tire can be directly observed after disassembly.
6, before disassembling the wheel bolts, you must first remove the fully closed wheel decoration cover. When disassembling, the decorative cover can be removed directly by hand. To install, make sure that the valve mouth opening of the decorative cover is aligned with the valve mouth and gently press to the rim, then clamp the entire outer edge of the decorative cover into the steel rim.
