When we first started to contact the West, Mercedes-Benz heavy trucks were specialized in cross-age NG73 heavy trucks. A batch imported from China was also NG73 heavy trucks, and the surveying and mapping imitation of the Iron Horse Factory was actually NG73 heavy trucks.
Later, when the Oriental Power formally inspected and proposed the need for technology introduction, it had been upgraded to NG80 heavy truck. This is an upgraded product and is not a complete replacement, but there are many improvement projects, including the engine and the chassis.
Even the cab has been improved, reducing wind resistance, etc.
Any factory will always be eliminated if it only stays at past grades.
Of course, domestic exceptions are. In the era of planned economy, Lao Jieyi has been producing for 30 years and has not been eliminated. However, further backwards, with the continuous development of the market economy, we can see many state-owned car companies continue to continue to operate.
The land has regressed, while private car companies are making great strides.
The reason is naturally the innovation ability. When a state-owned enterprise spent 50 billion yuan to develop a high-end sedan, most of which were surveying and mapping imitation. Private enterprises used a fraction of their R&D expenses to achieve it.
The product has been upgraded.
Only by constantly developing and upgrading can there be progress. It is absolutely impossible to lie down in the past and sleep. Just like upgrading from National V to National VI, many car companies lack R&D capabilities and do not have any vehicles sold in National VI.
As a result, it went bankrupt naturally.
Of course, Mercedes-Benz heavy trucks are constantly upgrading and improving. In 1980, the NG80 heavy truck was launched. In recent years, the R&D results have accumulated together. We have planned to further launch new heavy trucks. We plan to officially launch the market after the New Year.
Codename NG85.
The reason why Mercedes-Benz Heavy Trucks can agree to these requirements of the first machine factory is of course their own. The export technology is the NG80 series heavy trucks, which has been making money for five years. The technology of the newly launched NG85 heavy trucks is definitely not
Qin Zhenhua was just here to joke with the other party.
The upgrade of the NG85 series heavy trucks has made considerable progress. In terms of engines, the improved V8 engine can output 375 horsepower. If it were placed in later generations, this would not be a big deal, but now it is definitely a heavy truck engine.
The first.
Not only does it have strong power, it also takes into account fuel consumption. Even professional diesel engine companies like MTU are not as good as those of this.
The newly developed OM442LA engine is even more powerful. This V8 engine uses supercharged and intercooled, with a displacement of 430 horsepower. This engine has also been used in subsequent Mercedes-Benz SK models.
At the same time, they also have a V10 engine with a displacement of 18.3 liters specially provided for heavy-duty transport users, with a maximum power of 355 horsepower and a turbocharged version of 500 horsepower.
Civilian cars, equipped with a 500-horsepower engine, are definitely an amazing existence!
However, among the technological progress, the progress in the engine is shrouded in the advancement of another technology, which is the transmission!
In this era, heavy trucks are all manual gearboxes. Only tanks use expensive hydraulic gearboxes and have the ability to shift gears automatically. However, this has not been transplanted to ordinary civilian vehicles.
Because it has a torque converter inside, this thing will consume power. Heavy trucks that pursue economics cannot use this technology.
Mercedes-Benz did not give up. Liberating the left foot has a great effect. The frequent start and slowing of heavy trucks is a very heavy burden on the left foot.
You should know that heavy trucks in this era have already popularized nine-speed gearboxes. If you start and speed up, you have to switch gears nine times and step on the clutch pedal nine times!
Therefore, when Steyr heavy trucks entered the country, veteran drivers invented the way to shift gears without stepping on the clutch, which relies entirely on the accelerator. Except for stepping on the clutch when starting, they do not step on the other way. This method is not done.
, not only saves the clutch life, but also reduces the power delay.
Especially when you are on heavy load uphill, it takes a certain amount of time to step on and loosen the clutch. This time causes the loss of power, which may cause the vehicle to be unable to continue walking on the ramp.
The transportation in Europe is already very complete, and there will be no overload. They emphasize human comfort. Therefore, in order to make the driver more comfortable driving the vehicle, Mercedes-Benz Heavy Truck Company has developed a new set of automatic transmissions.
The gearbox, named Electronic power shift, is also the first in the heavy truck industry, and is supplied on the 1644 flagship model.
Of course, although the gearshift logic of this transmission is still not mature after several years of research and development, it is still a great innovation, and it laid the technical foundation for the future PowerShift automatic transmission.
It does not use a torque converter or other device. It is just a computer-controlled automatic shift mechanism installed on the basis of the original manual transmission. In fact, it is an AMT transmission, such as the axes of this transmission.
Waiting is inevitable, but this is a good start after all!
Mercedes-Benz has never had to keep it confidential. If you have any new things, you have to show off your technology as the world's number one in the heavy truck factory.
Therefore, their technologies have been widely publicized for a long time, and it is normal for Qin Zhenhua to know about them.
"We are very interested in the automatic shifting technology you are studying. I hope these technologies can be introduced as well, and assembled according to the standards of Model A cars." Qin Zhenhua said with a smile.
Once you get it, you can disassemble it and study it. After disassembly, you can imitate it. If all military vehicles are made into automatic transmissions, it will definitely greatly reduce the operating burden. Moreover, it can also be made into a technology.
What a reserve, our military-to-civilian project is a heavy truck, so we naturally need to target the world's most advanced heavy truck technology.
As soon as he said this, the two people on the other side looked at each other, and no one could speak.
"This song is good. Qin, do you want us to dance?" Mia said from the side.
Now, the main thing has been concluded, and the two sides have reached an intention. There will be many rounds of detailed negotiations in the following way. However, Qin Zhenhua obviously had too high demands. In order not to destroy the atmosphere, Mia came to invite her to dance.
Generally, men invite women, Mia takes the initiative to invite Qin Zhenhua to jump. If Qin Zhenhua doesn't agree, it would be too ungenius.
So Qin Zhenhua entered the dance floor with a smile. Soon, Mia frowned and almost screamed, stop stepping on my feet!
