What is the manufacturing process of car wheels?

There are mainly three manufacturing processes for car wheels: 1. Forging: This forging process can be further divided into gravity casting and low-pressure casting. The gravity forging process is very simple, where the liquid alloy is poured into the mold and naturally forms under the action of gravity, resulting in relatively low costs. Low-pressure casting uses low pressure to compress the liquid alloy into the mold. Wheels produced this way have higher metal density, greater strength, more complex shapes, and higher safety factors. This is currently the main method for manufacturing aluminum alloy wheels, with relatively high yield rates and automation levels. 2. Casting: High pressure is used to press a preheated alloy into a rough wheel blank, which is then subjected to secondary processing on the production line. As a result, the shapes are relatively simple, and the surfaces of the wheels mostly feature straightforward, rugged lines. 3. Spinning process technology: This process has certain requirements for pressure and temperature. By utilizing rotational motion and extrusion, the structure of the wheel rim is extended. Wheels produced this way not only meet the required strength standards but also significantly reduce the weight of the wheels.

Is the Driving License Reissued at the Place of Issuance or Residence?

Driving license reissuance should be applied for at the vehicle management office of the place of issuance or registration. The vehicle management office shall reissue or replace the driving license within one day from the date of acceptance. Here is the extended information: 1. Relevant matters: Fill out the application form, inspect the motor vehicle, and submit the following certificates and vouchers: the identity certificate of the motor vehicle owner, the proof of origin of the motor vehicle such as the purchase invoice, the whole vehicle factory qualification certificate or the import certificate of the imported motor vehicle, the tax payment certificate or tax exemption certificate of the vehicle purchase tax, the compulsory insurance certificate of motor vehicle traffic accidents, and other certificates and vouchers that should be submitted when registering the motor vehicle as stipulated by laws and administrative regulations. 2. Verification and review: The vehicle management office shall confirm the motor vehicle, check the vehicle identification code imprint film, review the submitted certificates and vouchers, and issue the motor vehicle registration certificate, license plate, driving license and inspection qualification mark within two days from the date of acceptance of the application. At the same time, if applying for reissuance of two-sided license plates, the local police station or the police station of the place where the license plates were lost shall issue a loss certificate.

Which is better, DCT or AT transmission?

AT transmissions and DCT transmissions each have their own advantages and disadvantages. Both dual-clutch and manual-automatic transmissions are currently popular automatic transmissions, but these two types of transmissions have different characteristics, just like the different working styles of different people. Cars with manual-automatic and dual-clutch transmissions differ in terms of power acceleration, convenience, and technology. More details about DCT and AT transmissions are as follows: 1. Introduction one: The role of the dual-clutch is to eliminate the power transmission stagnation during gear shifting. It is mostly used in sports cars. With a regular clutch, when you press the clutch to shift gears, the power is cut off, causing stagnation, whereas the dual-clutch does not or has a very short stagnation time. Manual-automatic transmission combines the manual and automatic shifting methods of a car, meaning you can either just press the accelerator for automatic shifting or manually shift gears. 2. Introduction two: The advantage of manual-automatic transmission is that it allows for relaxed driving while also recovering some driving pleasure. The disadvantage is poor fuel economy. Ordinary manual-automatic transmissions are developed from traditional automatic transmissions. These transmissions have prominent +/- signs, and the driver can switch to this position for manual gear shifting. However, the manual mode of ordinary manual-automatic transmissions cannot be compared to manual transmissions in terms of response speed, and the improvement in driving pleasure is very limited.

What are the tire requirements for the 2021 annual inspection?

2021 annual inspection tire requirements include checking the tread depth of the tires during the inspection. Below is an introduction to the latest 2021 annual inspection regulations: 1. Cancelled items: Power performance test, interior noise test, electronic parking brake test, headlight deviation test, suspension test, speedometer error test. Among these, the exhaust emission test was basically performed by the inspector flooring the accelerator. However, starting next year, the vehicle power test will be replaced with an OBD test, which is more convenient and less harmful to the vehicle. Tests like suspension and speedometer error have been cancelled as they are deemed unnecessary due to industrial advancements and improved vehicle quality. 2. Newly added items: Tire tread depth test, vehicle wheelbase test, and vehicle lifting device. The tire tread depth test will have a relatively significant impact on car owners, as many do not have the habit of regularly changing tires and continue to use aged tires, which reduces the friction between the tires and the road, increasing the risk of skidding and other dangerous situations. Under the new standards, the tread depth of tires will be checked during the annual inspection, and if the tires are severely worn and the depth does not meet the standard, the vehicle will fail the inspection.

What should I pay attention to when taking a long-distance bus?

Things to pay attention to when taking a long-distance bus are as follows: 1. Find a comfortable seat: Book your ticket in advance or arrange for a comfortable seat through acquaintances, as the limited space in the bus can make crowding uncomfortable. It's best to choose a seat you prefer. 2. Avoid strong-smelling areas: Since long-distance sleeper buses have toilets that are difficult to flush, try to stay as far away from them as possible. 3. Be cautious with valuables: As it's a crowded area, make sure to keep your wallet and valuables secure to prevent theft by potential criminals. 4. Prepare snacks to avoid hunger: Long-distance buses usually stop at fixed rest service areas for meals. While the driver eats for free, even if delayed by traffic, the bus will still aim to reach that service area. So, bring your own food just in case. 5. Beware of sexual harassment: Many men may leer at attractive or scantily clad women, and there's no telling what they might do. 6. Pay attention to safety: Since the bus is driven by a human, there's a chance of fatigued driving. Always be mindful of your safety.

What are the dimensions of a 9.6-meter-long vehicle?

Length 9.6 meters, width 2.3 meters, with 8 wheels at the rear, and a standard load capacity of 18 tons. Taking a 9.6-meter high-barrier truck or a 9.6-meter four-front-four-rear (four-front-eight-rear) truck as an example: 1. Net cargo compartment length: For a 9.6-meter truck, the net compartment length is usually 9.6 meters (internal dimension of the cargo compartment barrier: 9.6 meters), excluding the truck head, the maximum length for loading is within 9.6 meters; 2. Net cargo compartment width: Net width 2.3 meters (internal dimension of the cargo compartment barrier: 2.4 meters), more precisely 2.35 meters, the width of loadable goods should be within 2.4 meters; 3. Cargo floor height: Approximately 1.3-1.5 meters from the ground to the cargo floor; 4. Compartment height: From the cargo floor to the compartment barrier is 0.5 meters to 2.1 meters (internal dimension of the cargo compartment barrier: 0.5 meters or 2.1 meters), total compartment height is 2 meters to 3.6 meters, with a loadable volume of 60 cubic meters; 5. Total vehicle mass (vehicle's own weight): 9-11 tons, general load capacity: 15 tons, maximum load capacity: 25 tons.
