Why are American, German, and Japanese cars more extreme in their choice of gearbox?

First of all, we know that two of the world's three major transmission manufacturers are Japanese, that is, Aisin and Jiecott, of which Toyota holds about 23% of Aisin's shares, and Jiecott is a joint venture of several companies, Nissan holds 75%, Mitsubishi accounts for 15%, and Suzuki holds 10%.

Because Jackcot is most famous for its CVT continuously variable transmission, which can be called world-class, Japanese brands such as Nissan, Mitsubishi, and Suzuki will definitely use their own products, and their models will naturally use Jackot's CVT gearbox.

Aisin produces both CVT gearboxes and manual automatic transmissions, because the CVT gearbox has a very smooth shifting experience, and fuel consumption is very economical, so Toyota's low-end family models are all using CVT transmissions, and high-end models are using manual automatic transmissions. Volkswagen, the representative of German cars, also used CVT and manual automatic transmission at the beginning, but due to the annual payment of a lot of patent fees, so the rear wheel simply made a DSG dual-clutch by itself, in fact, the manual transmission added an electromechanical unit, but it is also considered an automatic transmission, and has complete intellectual property rights, so Volkswagen and Volkswagen's sub-brands have begun to use the DSG dual-clutch transmission.

However, Mercedes-Benz and BMW, which are German brands, still continue to use manual transmissions, because they are not sub-brands of Volkswagen, so naturally they will not use Volkswagen's dual-clutch transmissions. Many of these automatic manual transmissions are supplied by ZF, one of the three major transmission brands, and some are supplied by Aisin.

Because they are already relatively mature in technology, they dare to try this extreme configuration.

Because they have their own ideas and design concepts, the choices are more extreme.

This is because the gearbox is the soul of a car, so it generally pays great attention to the gearbox.

Because these countries are relatively extreme in car manufacturing, their technologies are relatively mature.

Because a good engine can make the car perform better.

JECT is a joint venture between several companies, with Nissan holding 75 percent, Mitsubishi 15 percent, and Suzuki 10 percent.

Because their designers may want to go to extremes, they want to be the best.

Because the quality of the engine can reflect the quality of the car, the high-end engine will make the car better.

Because they may want to make a car that they build to maximize its performance.

An engine is something that provides power, and improving its quality is what improves the overall level of the car.

American cars can build good gearboxes. While it is true that the durability, failure rate, and shift response of American automatic transmissions are not as good as those of Japan's Aisin, JATCO, and Germany's ZF transmissions, the overall gap is not too large. At least American Ford can make 6AT independently.

8AT gearbox, GM can produce 6AT, 9AT gearbox, at least don't have to buy it from outside, I think the strength of American cars is still there, but the design and manufacturing process is not perfect enough, resulting in some performance The gearbox is not as good as Japan and Germany, but it does not mean that the United States cannot make a good gearbox.

This is due to the inability to pursue a higher level in the design and manufacturing process, which leads to transmissions that are inferior to those in Germany and Japan.

Because American cars are relatively weak in the field of gearbox, they always prefer to study the engine, and the Americans pay attention to speed, so the field of gearbox is not very professional research, the main technology of the gearbox is mastered in Germany and Japan, the United States does not have professional technology research and development, so it is always not good to build the gearbox.

1. The early American cars tended to be large, focusing on comfort, especially in the rear, and paying attention to the atmosphere. This is also more in line with the character of Americans. Another consequence of the large is the high fuel consumption.

It's powerful, but it's not precise enough. If the German car is a sniper rifle, the American car is a rumbling artillery fire.

But now American cars are beginning to develop in the direction of refinement. The overall size is not as wild as before, but more and more like European cars, hehe.

2. The German car is rigorous, the power output is relatively stable and mature, the driving pleasure and ride comfort are taken into account, and the fine workmanship is the biggest feature of the German car, which makes the German car very safe.

American cars pursue a high safety coefficient, typical representative of Buick, German cars are traditional economic and energy-saving (Volkswagen) + high safety factor + strong power (Opel, BMW, Mercedes-Benz) in one of the high-performance cars, hope to adopt, thank you!

There are many brands of American cars, and the more common ones on the market are Ford, GM Buick, Chevrolet, Dodge, Cadillac, Hummer, Jeep, and Lincoln Tesla.

The AT gearbox of American and Japanese cars is different. First of all, the AT gearbox was originally invented by the United States and used in American cars. Later, after the Japanese learned from the group, they also began to develop gearboxes, and Japan made the world's first automatic transmission, and carried it forward.

Now Toyota Motor Corporation holds the Aisin Transmission, which is the first in the world. To sum up, the American gearbox was invented by the Americans, and the Japanese gearbox was invented by the Japanese after learning. Secondly, in terms of function, the gearbox of American cars has 9 or 10 speeds, but it is still not as smooth as the gearbox of Japanese cars.

In contrast, the gearbox of American cars is smaller, and it is easy to feel a little weak. In addition, the maintenance cost is relatively high, and if it is not maintained in time, it may lead to major repairs. Japan's Aisin gearbox shifts smoothly, the transmission efficiency is high, the economy is also good, and the maintenance on time can also be driven to scrap without breaking.

Thirdly, the engine power system of American cars is relatively strong. However, the gearbox of American cars is easy to become the main reason for the decline in its value retention. The maintenance cost of the gearbox of American cars is high, while the maintenance cost of the gearbox of Japanese cars is low, the gearbox is smooth, and the fuel economy is good or slag.

In the end, although the AT gearbox of American cars was the earliest invention, the Japanese Aisin gearbox made it more perfect.

For friends who often drive, it can be said that it is inevitable to encounter problems with the car. For example, what kind of transmission is used in American cars? I believe that everyone often encounters the small problems of these cars, so today Bian Xiao will tell you about it, hoping to help you.

According to the introduction of some American car owners, American cars generally use automatic manual transmissions, such as Buick and Ford. This kind of gearbox is the most traditional gearbox, its manufacturing cost is relatively low, and it is not easy to be damaged, and the cost of later maintenance is relatively low. About automatic manual transmission:

The automatic manual transmission is the most traditional and simplest of the automatic transmissions. The automatic manual transmission is a kind of variable speed wax cooker device that combines the functions of manual transmission and automatic transmission. The owner can automatically change gears through the computer, or he can change the gears impulsively by himself, which improves the driving pleasure of the car to a certain extent.

Cars equipped with automatic manual transmissions are generally divided into four basic gears: P, R, N, and D, and P is the parking gear, which is used when the car is parked for a long time. At this time, the car is braked, but it must also be used with the handbrake. R is a reverse gear, which is used to reverse as the name suggests.

When the car is reversing, it is necessary to pay attention to the rearview mirror to prevent potential safety hazards. n is neutral, which is generally used when waiting for a red light, but should not be used to coast, otherwise it will wear out the gearbox. D is the forward gear, which is the most basic gear for automatic transmission cars.

According to the mediator fuel of some American car owners, American cars generally use automatic manual transmissions, such as Buick and Ford. This kind of gearbox is the most traditional gearbox, and its manufacturing cost is relatively low, and it is not easy to be damaged, and the cost of later maintenance is relatively low.

About Automatic Manual Transmission:

The automatic manual transmission is the most traditional and simplest automatic transmission. An automatic manual transmission is a transmission device that combines the functions of a manual transmission and an automatic transmission. The owner can automatically shift gears through the computer, or he can change the gears himself, which improves the driving pleasure of the car to a certain extent.

Cars equipped with automatic manual transmissions are generally divided into four basic gears: P, R, N, and D.

P is for parking gear, which is used when the car is parked for a long time. At this time, the car is braked, but it must also be used with the handbrake.

R is a reverse gear, which is used to reverse as the name suggests. When reversing, be sure to pay attention to the rearview mirror to prevent potential safety hazards.

n Neutral is generally used when waiting for a red light, but not for coasting, otherwise it will wear out the gearbox.

D is the forward gear, which is the most basic gear for automatic driving of the car.

Millions of car purchase subsidies.

According to the feedback of major Japanese car 4S stores and Japanese car owners, the variable speed macro potato box of Japanese cars is generally CVT continuously variable transmission, such as Toyota, Honda, Nissan and other cars. The CVT shifts smoothly and has good fuel economy, which can reduce the fuel consumption of the car to a certain extent.

A continuously variable transmission is a type of continuously variable transmission. The difference between CVT and a normal automatic transmission is that the gear ratio is not a discontinuous point, but a series of continuous values. As a result, it allows the car to shift gears more smoothly without wasting too much fuel consumption and makes the vehicle's fuel economy more prominent.

There is no gearbox in the CVT transmission, so the power output of the vehicle equipped with the CVT is relatively linear, and there is no frustration when changing gears. Cars equipped with CVT transmissions also have better smoothness in shifting, with relatively little frustration when shifting. Moreover, the CVT gearbox has high transmission efficiency, and can also simulate various gears, making the gear setting more free.

However, compared to conventional automatic transmissions, CVTs are more expensive to repair and maintain. Moreover, the transmission capacity of CVT gearboxes is limited, and they are generally not installed in large-displacement vehicles.

<> "It's no secret that there is a "chain of contempt" in all walks of life, and the same is true for the automotive industry. Those who drive off-road look down on urban SUVs, those who drive executive business vehicles look down on entry-level small cars, and those who drive joint venture cars look down on domestic ......carsThere are not only models but also factions, especially in the car market with many factions, and the chain of disdain is even more diverse. For example, this one - German, Japanese, American, Korean, and domestic cars.

Of course, in the continuous development, the order will also change, for example, the current ranking of domestic cars and Korean cars is very delicate. However, the division of the three categories of German, Japanese, and American is still relatively unified. At least judging from the feedback on the Internet, the American system does not perform as well as the other two, why?

In fact, it is not that the strength of American cars is not strong, American cars are not necessarily inferior to Toyota and Volkswagen in terms of history, or Ford and Chrysler, in terms of technology, Ford EcoBoost series engines are also frequently on the list of Ward's top ten, and on successful products, Chevrolet Cruze is also a classic model that sells well all over the world. But the overall impression is that the American system is always inferior to the other two, what is the difference?

One is the reputation of the market and the feedback of car owners, on the whole, the performance of American cars is indeed inferior to German and Japanese cars. Why? Take Focus as an example, this product is also a classic product with a history of more than 20 years, but it has always missed the championship, the domestic champion is Lavida, and the global champion is Corolla.

Why not Fox? Obviously, it's too rough in workmanship. American cars also have this common problem, it is more like a strong but informal elite, the materials and layout and the attention to detail, are far inferior to the German and Japanese cars.

On the other hand, Volkswagen, Jetta, Bora, and Lavida are in terms of space and appearance, including the intentions of configuration, and they are looking at the first three generations of Focus.

may also suffer this loss, the new Focus has finally changed, whether it can change the label and impression of rough workmanship, you have to take your time. But this generational replacement is really too slow, including Mondeo, Taurus, etc., are they considering a generational change!

The other is that the sales figures in the auto market reflect the sales group, and the American cars are far from competing with German and Japanese brands. If there was a Yinglang in the field of sedans in the past to win glory for American cars, now it is also cold.

From the perspective of brand sales, Volkswagen, Toyota, Honda, and Nissan are significantly better than American brands. The best-performing Chevrolet's monthly sales are even more different from Volkswagen's, not to mention Ford's. Even the Toyota Camry and Honda Accord are constantly adjusting themselves for the market, and the changes in American cars in this regard are not enough.

This is one of the main reasons why it is inferior to the Ashkenazi Japanese system.

Many car lovers find that Japanese brand models like to use CVT gearboxes, such as Honda, Toyota, Nissan, Subaru, Mitsubishi and other brands all use CVT gearboxes, while European models like Volkswagen, Audi, BMW are almost equipped with their own clutch gearboxes, rarely use CVT gearboxes. What are the advantages and disadvantages of CVT gearbox? Next, let's analyze and analyze for everyone.

First, the characteristics of CVT gearbox.

Compared with the traditional AT gearbox, the CVT is simpler and smaller, and does not have more gears than manual transmissions, nor does it have the complex gear set of automatic transmissions, and mainly relies on the main and driven wheels and metal strips or rolling discs to achieve stepless changes in the speed ratio. Compared with the traditional gearbox, the CVT gearbox replaces the complex and cumbersome gear set with two sets of pulleys, which reduces the manufacturing cost of the gearbox. And the CAD gearbox is also 10 points fuel-efficient, which can achieve continuously variable transmission in a fairly wide range, so as to obtain the best match between the drive train and the engine working conditions, and improve the fuel economy of the car.

Second, the shortcomings of CVT gearbox.

The disadvantage of CVT gearboxes is that European manufacturers almost do not use CVT gearboxes. Everyone knows that Japanese cars are more suitable for daily use, so the purpose of the car is more clearly divided. Most of the European cars focus on the power and sportiness of the car, even if it is used for family use, it also has good power and handling, so the CVT gearbox can not meet the European model.

The CVT gearbox is not suitable for intense driving, if the torque is too large, it will cause the steel belt to slip, and the CVT gearbox is powered by the steel belt, so it will cause the gearbox to heat up, resulting in abnormal noise. At this time, the CVT's transmission overheating protection will be activated, so that the car has fuel but cannot increase the speed.

The disadvantages and advantages of CVT's gearbox are very distinct. If you are buying a car for domestic use, a CVT gearbox is a good choice, and if you are driving for a long time, you will choose a European car.
