How to play the secret of 4WD how to become a 4WD master? ）

The car made of Audi high-tech technology has become the leading excellent style of Audi four-wheel drive, the car is made of high-tech dedicated materials, equipped with a sonic motor, ultra-high-speed gears to become a strong racing car Audi four-wheel drive car parts role and installation: four-wheel drive car parts are many, four-wheel drive car is to cultivate hands-on ability and knowledge of a toy, four-wheel drive car parts car speed and parts are also a lot. Personally, I don't think 4WD is more beautiful than knowledge.

It does not need to be lightweight. Run fast. If you don't fly, you play 4WD.

I'm going to tell you about the parts and fittings of an Audi 4x4.

Lubricating oil: This is to reduce friction, reduce the friction caused by some parts of the car when they are in motion, and some parts.

The faster the movement. It can be painted on the interior and gears of an Audi 4WD.

Run-in: When the car is installed, do not immediately lubricate the car to rotate first, and then open the gear set to remove the powder, and the run-in is considered successful.

Tires: There are two types of tires, one is rubber and the other is sponge. In fact, it is not good to buy tires that are a little more expensive, like being able to be on five tracks.

The Dragon performs better than sponge tires on the standard track. Sponge tires are better than rubber tires only on the Lightning Wyvern runway.

Visiting is the first step on your path to becoming a master.

Willing to spend money on advanced equipment Maintenance and repair are also very important.

Just equip it properly! Hehe.

The benefits of four-wheel drive vehicles are mainly manifested in sufficient power, very stable when turning, not easy to slip during driving, strong grip, and high passability, and at the same time, according to the different conditions of the road surface, the engine output torque is distributed on all wheels in different proportions before and after, so as to improve the driving ability of the car. The disadvantage is that the fuel consumption is relatively large, the maintenance is more complicated, and the energy loss when the vehicle is in the high-speed driving state is also more.

There are three main types of four-wheel drive, namely full-time four-wheel drive, time-sharing four-wheel drive and timely four-wheel drive. Full-time four-wheel drive is the transmission with the highest cornering limit on the road, allowing the vehicle to optimally distribute the driving force to each wheel when cornering at high speeds. But the structure of full-time drive is more complex, the cost is also high, the power consumption is larger, and it is not suitable to be installed on the general small economic vehicle; The structure of time-sharing four-wheel drive is simpler, the reliability is also better, the cost is lower than that of full-time drive, and it is also more flexible, but the time-sharing four-wheel drive has higher requirements for driving technology, because time-sharing four-wheel drive is equivalent to a hard shaft connection after being turned on, and this mode needs to be cautious; The cost of timely four-wheel drive is lower, and compared with full-time four-wheel drive, it can effectively reduce the weight of the vehicle, but when the timely four-wheel drive transmits power to the front and rear axles, it will be affected by the structure of the vehicle itself, and more than 50% of the power cannot be transmitted to the rear axle.

Is a 4WD useful If you don't have special needs, such as climbing up a hill or something, or often walking on rough roads, there is not much need! Depending on the individual situation, you can also choose between front-wheel drive and four-wheel drive convertible.

If you don't have special needs, such as climbing up a hill or a lot of rough roads, there is not much need! Depending on the individual situation, you can also choose between front-wheel drive and four-wheel drive convertible.

The vehicle with all-wheel drive has the following advantages:

1 Since all-wheeled vehicles can use the full weight of the car as the adhesion pressure, the adhesion is significantly increased, that is, the traction limit is extended;

2. The power of the engine can be transmitted to each wheel separately, that is, the driving force burden of each driving wheel is reduced, so that it can ensure that enough power is transmitted to the road surface under the condition that the tire friction limit is not exceeded (wheel slippage does not occur), so that the car has strong off-road ability;

3 The wear and tear of the tires is uniform, which is conducive to prolonging the service life of the tires.

At the same time, the all-wheel drive type has the following drawbacks:

1.The transmission system is long, the structure is complex, the manufacturing cost is high, and the maintenance is difficult;

2.The noise is high, the vehicle is heavy, and the driving force transmission efficiency is low, and the fuel consumption is large, that is, the fuel economy is not good.

1. Some vehicles are switched through the gear lever, so as to complete the switching between the two-wheel drive system and the four-wheel drive system of the vehicle, and the general four-wheel drive system has high-speed four-wheel drive and low-speed four-wheel drive, and the owner can switch between these two modes. 2. Some vehicles are switched by knob, that is, to switch the terrain mode of the vehicle, and the owner can also choose high-speed four-wheel drive or low-speed four-wheel drive, or choose the vehicle's two-wheel drive system.

Hello dear, according to your question to provide you with the following, for reference only: The following is how to switch to four-wheel drive and four-wheel drive. 1. Some vehicles are switched through the gear lever, so as to complete the switching between the two-wheel drive system and the four-wheel drive system of the vehicle, and the general four-wheel drive system has high-speed four-wheel drive and low-speed four-wheel drive, and the owner can switch between these two modes.

2. Some vehicles are switched by knob, that is, to switch the terrain mode of the vehicle, and the owner can also choose high-speed four-wheel drive or low-speed four-wheel drive, or choose the vehicle's two-wheel drive system.

How can the four-wheel drive mode be hung into a two-wheel drive mode?

The specific operation steps of Honda CRV four-wheel drive to switch to two-wheel drive are as follows: 1. Press the brake pedal of Dongfeng Honda CRV and prepare to start the engine. 2. Press the one-button start button of Dongfeng Honda CRV to start the engine.

3. The dashboard of Dongfeng Honda CRV lights up, and the power supply of the whole car is turned on. 4. Twist the drive mode knob to 2WD to turn on the two-wheel drive mode.

Full-time drive and just-in-time drive: Because urban four-wheel drive vehicles are oriented to ordinary consumers and meet the needs of the urban environment, the drive mode emphasizes intelligence and ease of operation, and generally adopts full-time drive and timely drive.

Part-time drive: Mainly used in off-road vehicles, the driver's skills and experience requirements are quite high.

Hybrid drive at the right time: a balance between precision and ease of use.

The biggest difference between full-time drive and just-in-time drive is that the full-time drive vehicle always maintains the four-wheel drive mode, and the engine output torque is set to the front and rear wheels at a ratio of 50:50 during normal driving. When the tires slip, the front and rear torques are automatically distributed to ensure excellent vehicle performance and driving conditions on different road surfaces, with a distribution ratio between 30 70 and 70 30 (front and rear drive torque 30-70 continuously and infinitely adjustable), vehicles with this drive mode generally have good driving handling and greater comfort.

Timely four-wheel drive: choose which drive mode is controlled by the computer, the normal road surface generally adopts two-wheel drive, if the road surface is bad or the drive wheel is slippery, the computer will automatically measure and immediately distribute the engine output torque to the other two wheels, switch to the four-wheel drive state, eliminating the driver's judgment and manual operation, it is very simple to use.

What is the difference between the front wheel drive and the four-wheel drive of the car? You'll understand after reading it.

Part-time four-wheel drive is the earliest four-wheel drive system, and the driver can choose between two-wheel drive or four-wheel drive mode by switching the transfer case on or off. On pickup trucks, time-sharing four-wheel drive is generally divided into three gears: 2h, 4h, and 4l, which is often said to be two-wheel drive, high-speed four-wheel drive, and low-speed four-wheel drive - two-wheel drive mode (2h) is suitable for driving on urban roads or paved roads, high-speed four-wheel drive (4h) is suitable for walking on gravel roads or used in rainy and snowy weather, and low-speed four-wheel drive (4l) is suitable for off-road climbing and other troubled environments.

In domestic pickup trucks, time-sharing four-wheel drive is the most widely used form of four-wheel drive, whether it is Jiangling Baodian, Great Wall Fengjun 5 and other classic pickup models, or this year's latest entry into the market SAIC Maxus T60, Zhengzhou Nissan Navarra, 2018 Jiangxi Isuzu D-MAX, etc., all use time-sharing four-wheel drive system. For pickup truck users, the advantages of time-sharing four-wheel drive are obvious, simple structure, high reliability, and good off-road ability, and ** is not high, although it needs to be manually switched by the driver, it is more complicated for novices, but the driver can choose the drive mode through the actual situation, save fuel when you want to save fuel, and have energy when you want to climb, which is very economical and practical.

Do you really understand 4WD? A detailed explanation of the mainstream four-wheel drive system of pickup trucks.

Timely four-wheel drive. Advantages: simple structure, light weight, high transmission efficiency.

Disadvantages: Slightly inferior in extreme off-road ability.

Representative model: the all-new JMC Tiger.

Just-in-time 4WD is also known as real-time 4WD, as the name suggests, it will only be converted to four-wheel drive when the right time is right, and in other cases it is still two-wheel drive. Contrary to the manual operation of the time-sharing four-wheel drive, the system is controlled by a computer chip, when the vehicle is driving on a flat road, it will switch to two-wheel drive, which is conducive to reducing fuel consumption, and when the road surface with low adhesion such as bumps and slopes and bends, the vehicle will automatically switch to four-wheel drive mode. However, the physical structure limit of the 4WD is low when dealing with bad roads, so it is not suitable for difficult off-road sections.

The toys we used to own or crave were similar most of the time, and the problem even lingered as a reminder of our childhood.

Mini 4WD

Four-wheel drive must be one of the easiest childhood memories for many friends, especially boys.

Whether it is the "4WD Kid" and "4WD Brothers" animations that people look forward to every day when they came home from school when they were children, or the classic Audi Double Diamond, my partner, I believe that many people have played or watched others play with four-wheel drive cars when they were children.

With the broadcast of the cartoon "4WD Brothers" in 1996, the four-wheel drive car Wu Dashu began to become popular all over the streets, and I still remember discussing with my classmates at that time who has the most powerful four-wheel drive car and which car is the most handsome. And once anyone can own such a toy car, they will definitely become one of the best stars among children.

Four-wheel drive vehicles have actually appeared very early, and its more formal term should be called mini four-wheel drive. In 1982, the model company reduced the remote control racing car for professional competition, removed the steering and remote control, and successfully created a mini four-wheel drive car, which was quickly popularized around the world through the core of the model assembly + racing competition.

Compared with remote-controlled racing, the mini 4WD has a lower barrier to entry, and it has become a dream in the hearts of children since then. Its assembly is not complicated, and the different styles are basically only the shell is different, the structure is similar, through hands-on assembly, transformation, and battery, it can run on the ground at a very fast speed, so to some extent, the scene of chasing a car in roller skates in the cartoon is actually quite realistic.

With the end of the cartoon, the popularity of four-wheel drive cars in China has gradually decreased, but it has opened many people's initial model memories, so as to cultivate today's model party, and many people are fascinated by machinery, which may be the greatest fun that four-wheel drive cars bring us.

The assembly of four-wheel drive vehicles needs to be adjusted according to different models and their own actual needs. The following will introduce you to the assembly method and related knowledge of the four-wheel drive.

1.Choose the right car model

Before assembling four-wheel drive vehicles, you need to choose the model that suits you, including light off-road vehicles, modified trucks, assembled SVN cars, etc. It is necessary to choose the model according to personal needs and budget, and the Zen family can be selected according to the terrain, driving conditions and purpose of use.

2.Buy the right accessories

Assembling a 4WD vehicle requires the purchase of various parts and accessories, such as the engine, transmission, chassis, suspension, braking system, tires, etc. You need to choose each one according to your needs and budget, and ensure that they are compatible with each other.

3.Frame assembly is carried out

The frame is an important part of the 4WD vehicle, which needs to be assembled step by step according to the design drawings and assembly steps. The position of each part can be marked with wires, and then drilling, welding, and assembling can be carried out. When assembling, it is necessary to pay attention to the accuracy and reliability of the installation to ensure the firmness and stability of the vehicle.

4.Assembling the engine, transmission, etc

When buying accessories, it is often necessary to fine-tune them and then install them one by one. The engine can be connected and fixed to the frame, and the brake system and transmission also need to be installed and connected accordingly. It is necessary to ensure that the installation position of each component is accurate and reasonable to prevent deviations.

In short, the assembly of four-wheel drive vehicles needs to be carried out according to different models and their actual needs, and the compatibility and installation quality of each component need to be carefully checked to ensure the safety and reliability of the vehicle. Furthermore, owning a 4WD vehicle also requires maintenance and repair, regular replacement of wear parts, etc., to meet the needs of different environments and uses.
