What does it mean when a car does not have a clutch pedal? This is definitely an automatic car! A car that does not require any intervention from the left foot, is completely controlled by the electronic system. Now, when looking
When the car didn't have a clutch, Philip was completely shocked.
What does this mean? The automobile branch of Yimai Factory is actually developing automatic gearboxes!
If it is a car, there are many types of automatic transmissions. The common one is an AT gearbox with a torque converter. It is flexible to combine the torque converter. As a suitable method, even if it is a tank, this kind of speed change is used.
Box. However, it causes a certain power loss. After all, the torque converter is not rigidly connected, and a large amount of energy will be dissipated in the hydraulic oil. Tanks are acceptable, cars are acceptable, but trucks are not able to do it.
.
What does trucks do? It makes money! Therefore, for car owners, the first requirement is fuel saving. On the basis of fuel saving, the comfort requirements must be taken into account, because what is saved is profitable.
Therefore, trucks cannot use AT gearbox, and there is no such gearbox specifically for trucks. The automatic gearbox used by trucks is only added to the manual gearbox, if
To be professional, it is called AMT transmission. This kind of transmission is the closest structure to the manual transmission, so the cost of modification is also the lowest, but at the same time, the design of this kind of transmission is also the most difficult, because it
You need to rely on your own processor to determine when to change the gear. This not only requires careful design by programmers, but also requires continuous testing, obtaining a large amount of data, and constantly optimizing the program in the data.
This is what Mercedes-Benz did. At the beginning, their automatic transmission was not good and could not even meet the requirements of the truck when starting. Therefore, it was also equipped with an additional clutch. When starting, the driver needed to be regular.
The same operation will be performed before shifting gears automatically.
Now? The products produced by Yimai Factory themselves had cancelled the clutch at the beginning, and all of them were automatic, which shows that they have made great progress in this field.
He knew that this was not imported from abroad, because of this high-end technology, all manufacturers kept it strictly confidential, and they would not take out their own good things to export, so that they would gain greater benefits by monopolizing.
Yimai Factory has actually aimed at this direction and carried out independent research and development, and has achieved results.
The three major items of trucks, engines, gearboxes, and one-machine manufacturers are all innovating. As for the axle, there is nothing to say at all. A mature axle can be used for decades. One-machine manufacturers have to do heavy trucks by themselves.
In addition, huge investment has been invested to carry out research and development of various projects.
When he saw this, a strange feeling surged in his heart. What the other party said to export the product to the European market in the future was not just a joke. The other party had such a goal and had prior goals.
A down-to-earth style!
s:
"Do you want to go up and try?" Qin Zhenhua said: "We are still debugging. Now, there are still many problems in the program, so there are shocks and pauses when shifting gears. We still have a long way to go
We will go, but we will continue firmly.”
In fact, automatic transmission is only a small part, and most car owners will choose manual transmissions. After all, manual transmission is the most cost-effective, but this high-end automatic transmission is to increase the grade of the factory.
Only with this kind of thing can it be said that it is a large technology manufacturer that can be used on high-end products.
At the same time, this is not only for civilian use. One-machine factory started with tanks. Even even the current automobile branch still produces wheeled infantry fighting vehicles. This type of wheeled infantry fighting vehicle is not used in
The few parts are directly transplanted from the truck, and the engine and gearbox are all like this. Now, research on this automatic transmission is not only for trucks, but will also be used in wheeled models in the future.
Infantry fighting chariot.
There is already automatic transmission on the tank, and the infantry fighting vehicle cannot be left behind. As time goes by, the army will definitely make this requirement. At that time, the first-machine factory has this technology and can directly
When you produce the finished product, you can bid for this product. They have always liked to prepare for the future.
At this time, putting these things out, Philip finally said nothing. He originally thought that the first machine factory could only produce backward NG80 heavy trucks. After leaving Mercedes-Benz, the first machine factory had to keep relying on its old capital. But he didn't expect that they had already
After conducting pre-research on various technologies, he looked at the cab again, but still didn't get on.
"No need." Philip said: "This time I came out, it opened my eyes. I didn't expect that you would have done so many things, and you will become our Mercedes-Benz opponents in the future. I really don't want to see it.
That day.”
This sentence is filled with emotion. Mercedes-Benz heavy trucks are a famous existence all over the world. Philip said that the automobile branch of a machine factory will become their competitors. This is definitely a great deal for the people on site.
Encouraged.
Since the other party has given in mercy, Qin Zhenhua has not continued to put pressure on the other party. After all, the other party is here to find fault, and Qin Zhenhua has to hit the other party's arrogance. Now the other party is convinced, so everyone is still good friends.
"In fact, we don't have to become opponents, we can also become partners." Qin Zhenhua said: "But we have very high requirements. You cannot bring out the most advanced technology, so we will have no foundation for cooperation."
However, our domestic transportation market is thriving, and many heavy truck manufacturers are looking forward to joint ventures. You can also contact other heavy truck manufacturers to discuss joint venture issues. Perhaps, they will accept the products you gave."
One machine factory is unwilling to ask for rags. After all, one machine factory knows that what others give is always someone else's, and only what they develop is their own. However, there are not many people who can have the awareness of one machine factory.
Many manufacturers show off by introducing foreign technology, thinking that they will become taller in this way. After all, in this era, there are still many people who admire foreign countries and fascinate foreign countries.
The first machine factory will no longer cooperate with Mercedes-Benz, but other factories may be waiting for it. At least, the few factories that Qin Zhenhua knew were in contact with companies like Volvo and Man, trying to build a joint venture heavy truck.
