Passenger car automatic transmissions are all 10 speeds, why manual transmission or 5 speeds?

Manual transmission 6 speed, and many trucks are 10 speed, but 5 speed is the mainstream now, manual transmission is more than 5 speed. At the beginning of the last century, automatic transmissions were still a rarity. Although the 3- and 4-speed automatic transmissions are equipped with very high-end models, many manual transmission models only have 4 or even 3 speeds, such as the old 212 Beijing Jeep.

After all, automotive technology and materials of that era were not so precise. China's first expressway, the Beijing-Tianjin-Tangzhou Expressway, was built in the early 90s of the last century, even if the speed is fast, the design speed can reach 100 kilometers per hour. So in that era, as a passenger car, whether it was manual or automatic, there was a lot of room for development.

Today, China's road network is very developed, and even highways such as Yunnan-Guizhou Road and Sichuan Road, which used to be more difficult than climbing to the sky, are also crossing highways. The state of the art of automotive manufacturing is also constantly improving, and all production vehicles have integrated electronic control systems. However, it seems difficult to increase the manual transmission in production cars when it reaches 5th and 6th gears, while automatic transmissions can now reach 10th gear.

SoFirst of all, it is certain that the displacement of the manual transmission cannot be increased too much at the technical level. When the material technology and reliability meet the standard, adding gears is not a problem, but a matter of human adaptability.

In the case of a large number of passenger cars, for example, the transmission ratios can be closely distributed, and when the power accelerates, the up-gear downgrade can also fall into the maximum torque output range. The sixth gear is generally used as an overdrive gear, mainly to reduce the speed of the vehicle, while taking into account the role of fuel consumption and noise reduction. The fastest speed is usually in 5th gear.

Although it is possible to change two gears, because the manually operated shift clutch is prone to slight shaking, even with this design, I think the driver will still shift gears, especially not to be a towing driver, who can't change so many gears.

But automatic transmissions are different. It is controlled by a program, and now the automatic transmission shifts faster than the manual transmission. By recognizing the computers and sensors in different road conditions, more precise gear shifts can be achieved and smoother and more comfortable power connections can be achieved.

Because the acceleration of the manual transmission is very fast, it cannot be compared with the automatic transmission, so the effect is the same.

Because the speed of the manual gear handle has increased, people can't operate it, so it's better not to improve.

Because automatic transmission is relatively easy to speed up, that's why it's expensive.

Because the automatic transmission accelerates relatively quickly. So the automatic transmission is 10-speed, the manual transmission is still 5-speed.

Because of the manual transmission, its acceleration is relatively slow.

Because manual transmission and automatic transmission are different, the design of manual transmission is more powerful.

I think maybe it's like this is the transition between them, so manual transmission or 5-speed?

Because the manual transmission is safer than the automatic transmission, the speed is lower.

This is mainly because if there are too many manual transmissions, it is difficult to change.

The main thing is that it's too complicated to change gears, and it's too dangerous.

Because they have different ways to distinguish them, so they can better distinguish them.

I think the 5th gear manual is better, because then you'll have better control and a better understanding.

I think the fifth gear is the best to use, the gear is simple and there are few minor problems with the gearbox, there will be no tooth punching, and the power is strong.

I think the six-speed manual is good, first of all, the six-speed manual has one more gear, the car's operability will be stronger, and secondly, the six-speed manual has a stronger variable function and is more durable, and finally the six-speed manual ** and the five-speed manual are not much different, and the best one is more economical!

Six-gear manual is good. Because the more gears, the better the performance of the car, the safer the car.

It is better to have 6 gears manually, and the quality and safety factor is higher than that of 5, so it can make the speed better matched.

It must be six gears good, so there is more room for choice.

Introduction: For some people who often drive automatic cars, they may not be very used to driving cars with manual transmissions. Because we found that many automatic cars have reached 10 speeds, but many manual cars are still 5 speeds, why is that? <>

People who may have driven a manual transmission car will feel very uncomfortable when they come to drive a hermit automatic transmission car. Because when these cars are driving, there will be some differences in gears, and there will be slight differences in gearboxes. So why has the automatic transmission reached speed?

Let me tell you about it today. The reason for this design is to make the automatic transmission car safer in the process of driving, and at the same time, it can also save the fuel consumption of the automatic transmission car. Because when there are many gears, the speed of the engine will not be affected much in the process of driving, so it also saves some fuel consumption.

After seeing this, the friends still have some questions, since the automatic transmission car has increased so many gears in order to save fuel consumption, why has the manual transmission of the car not changed? The reason why it is designed this way is because in the process of driving the car with manual transmission, these gears are now fully enough for everyone to use. In addition, the driver will also control the speed of the car in advance during the gear change process, so there is no need for too many gears to control the engine speed.

If there are too many parties, not only will it not be convenient to drive, but it will also make it more difficult for the driver to drive. <>

I believe that everyone has a general understanding of the gearbox of manual transmission cars and automatic transmission cars, so we should not use automatic transmission cars to ask for manual transmission, and also do not compare these two cars. Because when the two cars are in use, there are many performance gaps. For automatic transmission cars, it may be that the driver only needs to control the accelerator and brake when driving.

Therefore, more and more people now like to buy automatic cars, but there are still some people who prefer to drive manual transmissions with stoves and potatoes, because they feel that these cars are more stable when driving.

It is because the manual transmission car needs to complete the replacement of the bearing when changing gears, and the general gearbox of the 5-gear car is sold left and right, once the size of the gearbox becomes larger and larger, it may affect the hungry space of the engine compartment, which may lead to an increase in costs.

Because the manual transmission has a small sales volume, it has also been snubbed by the car manufacturer to a certain extent, and if the manual trembling gearbox is too much, it will become a friend and a burden.

Because the speed of the manual transmission is constant, and the 5th gear is relatively easy to control, it will be maintained at the 5th speed.

1st gear: It is the gear used to start, the vehicle travels to 10 yards, the engine speed can reach 2000 rpm, and then you can switch to 2nd gear.

Gear: When the vehicle reaches 20 yards, the engine speed can reach 2000 rpm, then you can switch to 3rd gear.

Gear: 3rd gear generally travels to 40 yards, and the engine speed reaches 2000 rpm, you can switch to 4th gear.

Gear: When the general speed reaches 60 yards, the engine speed reaches 2000 rpm, and then you can switch to 5th gear.

The gear is equivalent to 60-100 km/h, which is the top speed.

Note: When driving at a speed of 100 km/h in 5th gear and need to complete the overtaking maneuver, you can lower it to 4th gear to let the engine be in a higher torque output to complete the overtaking maneuver.

The first gear starts, the second gear follows the car slower, the third gear is overgeared, the speed is a little faster, and the fourth gear and the fifth gear are faster.

In our daily life, the car is a more common means of transportation, with the development of society, everyone's living conditions are getting better and better, many people also buy a car, because we use this kind of manual transmission when we practice driving in the driving school, so we have a feeling when buying a car, will give priority to manual transmission. In the market, there are two kinds of cars with manual transmission, one is five-gear, and the other is six-gear. So which of these two gearboxes is better?

Personally, I think that the sixth gear is better, because it is a new technology, and his allocation of gears is more reasonable, so it will make our fuel consumption and handling feel better. But again, because it is an emerging technology, there may be a certain gap in terms of performance compared to fifth gear. So, in the end, how to choose, or do you need to combine everyone?

So when buying a car, in addition to choosing the corresponding gearbox, what else do we need to pay attention to? <>

The first is the color of the car, we know that there are a lot of colors of the car, white, black, all kinds of colors, so how do we choose, of course, the first criterion of choice, must be based on our own preferences, and the second criterion, it needs to be combined with the market value preservation, generally speaking, black and white are more mainstream colors, so its market value retention rate will become higher, we will give priority to the choice. <>

Secondly, the brand of the car, in addition to the body color, the brand is also one of the main criteria for our selection, a brand, the meaning he represents is extraordinary, there is quality, there is reputation, there is service, these, the brand is reflected. So, we need to pay attention to it as well. <>

Of course, in addition to these, there are some other things that are also very important, so the specific situation needs to be combined with the needs of the individual and the individual's situation. I hope everyone can pay some attention, because such a choice is just once.

In the manual transmission, I think it is better to use the manual of the fifth gear, because the movement speed of the five-speed manual is not particularly slow, and it is not particularly fast, and it will be particularly comfortable to drive.

Six-gear manual is good. Because such a gearbox has better performance, and the quality is better, and it is also more durable, the service life is longer, and it is more convenient to use.

Six-gear manual is good. Because the more gears, the better the measurement and control of the car, the safer the car, and our safety will be more.

6th gear is a little better. This is a little smoother when changing gears, and the quality of the car is also very good.

Of course, it's better to have 5th gear, because people are now used to 5th gear, and 6th gear may be very uncomfortable.

6th gear is better, because 6th gear is more fuel-efficient, and it is also very time-saving and labor-saving, and it is more convenient to drive.

I think the 5-speed manual one is better, because the 5-speed manual operation is relatively simple.

But 6th gear manual is better, because 6th gear animals will perform better, and the quality will be better, and the feel will be better.

The 6-speed manual is better, I feel that the 6-speed manual is very convenient and very intelligent, so I am willing to buy the 6-speed manual.

Normally, the minimum speed of the fifth gear should not be lower than 30km h

The minimum speed referred to here is the speed at which stalling is likely to occur while driving in fifth gear. According to the experienced driver's response, as long as the speed is not less than 20km h of the normal range of the corresponding gear, then it will basically not cause stalling, but some dragging.

For example, the minimum speed of 5th gear should not be lower than 30 km/h, otherwise the engine will stall. In the process of driving, usually the speed of the car reaches 50 to rise to fifth gear, otherwise the speed and gear can not match, the gear shift will lead to a setback, if the setback is more serious, it will also lead to stalling.

Generally speaking, 5 gears for 60-70km h can be said to be a better fuel consumption. The corresponding speed from the first gear to the fifth gear The first gear is the starting speed, and the speed is generally 0-5km h. The second gear corresponds to a speed of 5-20km/h.

The speed of the third gear corresponds to 20-40kmh. The fourth gear corresponds to a speed of 40-60 km/h. The fifth gear corresponds to a speed of 60-100km h.

More than 60 kilometers per hour.

The speed of the five gears of the manual gear is 10 kilometers per hour, the gear is 20 kilometers per hour, the gear is 20 to 40 kilometers per hour, the gear is 40 to 60 kilometers per hour, and the gear is more than 60 kilometers per hour.

Manual transmission is a manual transmission, and its working principle is to change the transmission ratio of the meshing gear by changing the gear fork, and then change the driving torque to suit different working conditions.

First gear is the start, second gear is 30 km, third gear is 30-40 km, fourth gear is 40-60 km, and fifth gear is 60 km away.

In fact, there is no determination of the corresponding speed, the first gear is to start or need a large driving force to use, the second gear is less than 30 kilometers when the use of low speed, the third gear is 30-40 kilometers and rapid acceleration use, the fourth gear is 40-60 kilometers in the acceleration use, the fifth gear is the cruising gear, more than 60 kilometers of normal driving use, if according to the second floor of the driving method, the fuel consumption of the car will be very high, and it is not good for the engine.

Starting from the performance and safety of the car, no matter what the vehicle must be in the first gear, which is good for the vehicle engine or transmission system, reducing unnecessary mechanical wear and damage, if you start with the second gear, it will increase the torque of the engine and transmission system, and the enhanced wear force will increase mechanical wear. When starting with the first gear, you can give a little oil appropriately, flat and steady, don't rush to give oil, otherwise it will also increase mechanical wear and damage.
