"Baozhen, I heard you are back, I'll come and have a look." The next day, Qin Baozhen and Hua Dongjie were planning to open their own company in an office building that they had just vacated for them in the first machine factory.
I heard a voice.
When the voice came, Qin Baozhen smiled and greeted him: "Brother Erzhu, how can you, you, be a busy man? I am planning to come and find you when you have time."
The person who came here was Wang Erzhu. Over the years, Wang Erzhu has been in charge of the business of the automobile branch of the First Machine Factory. Now it has been booming. Wang Erzhu also has a lot of money every day. It is not easy to participate in tank matters occasionally. Now, why did Qin Baozhen suddenly come to find him? It made him a little strange. If he went to sit at home after get off work, it would be possible. Now it is working hours. Will he spend his working hours on his work? Come here I guess there is something to talk about at work.
"No, no, your career is just starting out and it is time to need support." Wang Erzhu said: "Since you are starting your own company, you need to pull the project. It is absolutely not enough to have a tank modification project.
I have another project here that I want to hand over to your company.”
Hearing this, Qin Baozhen was a little surprised: "Does your truck want to drive unmanned? Brother Erzhu, although driving unmanned cars is an inevitable trend, there is still a long way to go.
, If you are pre-research now, I don’t know how much money you need to invest, it’s a bit early for you to start.”
"No, no, we won't do that shadowless one, we will only do the ones that can be put into use now." Wang Erzhu said: "Baozhen, do you know automatic trucks?"
In this era, most cars are manually driven, even if they are cars, only some high-end cars are automatic. As for the automatic transmission of trucks, Qin Baozhen has never heard of it.
Automatic transmission is to save physical strength, so it is understandable to use automatic transmission in a car. Driver is a physical job, so can I use automatic transmission? You must know that if you don’t know how to clutch your legs
, those are not old drivers.
Hearing Wang Erzhu's words, Qin Baozhen's eyes were puzzled. At this moment, Hua Dongjie, who was standing beside him, said: "The automatic transmission of trucks is a trend, especially in Europe, such as Mercedes-Benz trucks, theirs
Automatic transmission is becoming more and more mature.”
Sure enough, this young man named Dongjie is knowledgeable! Wang Erzhu nodded: "Yes, you are right. We can't always follow the butts of foreigners. We also have to do technical pre-research. We speculate that heavy trucks will be launched in the future.
There will be more and more automatic transmissions, so we plan to start researching from now on.”
When it comes to trucks doing automatic transmission, Mercedes-Benz is definitely the first to take the lead. As early as 1985, Mercedes-Benz's NG series heavy trucks had EPS technology. The full name is Elei power shift. If translated, it is called "electronic power exchange".
". At that time, it was not called automatic transmission directly because it was relatively simple. It simply used computer-assisted shifting technology to reduce manual shifting operations. (Mercedes-Benz is still very pragmatic, unlike some companies,
There is a L2-level assisted driving system, so I arrogantly say that my car can drive automatically.)
In this way, after ten years of development, in 1996, Mercedes-Benz's first-generation Atros heavy truck was finally equipped with a gearbox with Telligent intelligent gear shifting program. People still did not directly call it an automatic gearbox, but just said it was an intelligent switch.
Gear control, which uses shift lever to control the gear shift of the pneumatic system, belongs to semi-automated operation and also shows the gear position of the high-end LCD instrument. At the beginning, for the convenience of heavy trucks, the clutch pedal was even retained.
, specially used when it started, but it was removed later.
In this way, until this year, the automatic transmission of Mercedes-Benz heavy trucks was officially named Powehift, which marked the final maturity of the automatic shifting technology of heavy trucks. At the same time, other heavy truck manufacturers have also gradually developed their own automatic speed change.
box.
"The introduction of automatic transmission by heavy trucks not only saves the driver's physical strength, but also drives in the most economical way, saving fuel for car owners." Wang Erzhu said: "If we don't study it now, we will be thrown away.
We can’t wait any longer. We have to develop this technology and then use it on our trucks. Even if it takes ten or twenty years, we have to mature it.”
"This, can't you do it yourself? Why do you need our company to help?" Qin Baozhen said.
"Because the software design is too complicated," Wang Erzhu said: "The automatic transmission of heavy trucks is composed of a set of pneumatic shift components based on the manual transmission. The hardware is not complicated, but in software, that is
It is very challenging, and the road conditions vary greatly. We must make our transmission have good adaptability anywhere. It is difficult for us to do it ourselves. It is better to leave it to professionals. Moreover, if you do it
Once it is done, it can also provide automatic transmission solutions to other heavy truck companies. In the future, your company will definitely develop."
The automatic transmission of a car is not hard-connected, and has a special torque converter. Therefore, the program is very simple and the car will not stumble. However, heavy trucks cannot do it. Heavy trucks use clutch and drivers' skills.
It is reflected on the left foot. If you are not skilled, you can't even get the car to start successfully, so it is quite challenging.
Of course, the heavy truck can also use the torque converter, but this will greatly increase the cost. It is not only the purchase price is expensive, but also the torque converter consumes additional fuel during use, which will also increase the user's usage cost.
Therefore, all heavy truck companies choose to add additional control units to achieve automatic functions based on manual transmissions. The professional name is AMT transmission.
This tests the technical skills. When the Mercedes-Benz truck was immature, it retained a set of clutches, which were specially used for use when it started. Wang Erzhu didn't have the confidence to do it himself. Anyway, Qin Baozhen was doing automation, and this gearbox
The automation is her profession.
Moreover, if this thing is made and mature, the prospects will be broad, and there are tens of thousands of them at any time.
