"The AMT transmission is currently in use in China, but this transmission is not suitable for our military vehicles." Wang Erzhu continued: "So, they must have a real AT transmission. As for the engine, they use Weichai.
The engine has a power of about 400 horsepower, and their military vehicles also use special independent suspension, have anti-lock systems, and even disc brakes."
Knowing yourself and your enemy, you will win every battle. Wang Erzhu has long been able to find out the details of these competitors. At this time, when he heard Wang Erzhu say this, Qin Zhenhua nodded: "It seems that they also know that they must use high technology.
The configuration is very good. This Weichai engine is really good."
When Steyer technology was introduced in China, Steyer's 615 engine was handed over to Weichai for production. Weichai was really powerful. It took several years to understand the technology of this engine, and then,
After improvement, Steyr's 615 engine has sprouted and blossomed in China and has grown vigorously.
The initial Steyr engine had a displacement of 97.liters and could output more than 200 horsepower. In Weichai's hands, the cylinder was quickly expanded to 11.6 liters, and the engine output reached 375 horsepower. In the later stage,
After continuing to improve, it reached 460 horsepower, and it could even continue to increase to a level of nearly 500 horsepower.
Thinking about the 500-horsepower diesel engine of the 59 tank, and thinking about the fact that today's commercial vehicles have achieved this power, it makes people sigh that the progress of the engine is too rapid.
"That's of course. Even the commercial vehicles we produce ourselves have many assembled Weichai engines. Customers recognize this engine, so we assembled it. Although many foreign joint venture engines have been introduced in China,
, Weichai engine has always had a good reputation."
Weichai is a typical example of self-reliance and continuous development. When heavy vehicle manufacturing is separated, Weichai specializes in engines and supports various factories. At the same time, each factory is not satisfied with the engine control, so it will also find foreign manufacturers to jointly invest.
Even Mercedes-Benz has built a joint venture engine with domestic heavy truck factories. Cummins and Deuts are blooming everywhere in China.
However, relying on its good reputation, Weichai still occupies the first role in truck engines in China.
"Now, their 11.6-liter engine is still developing further. After the cylinder expansion, it reaches 13.54 liters, and the power can exceed 500 horsepower, or even 600 horsepower. This is also the first domestic model of more than 500 horsepower.
"If you guessed correctly, the old factory should use this 11.6-liter engine with displacement. After all, this engine is mature, but if they want to use power to crush it
If we are overwhelmed, we might install the 13.54-liter engine, which will give the power more than 500 horsepower."
Before the bid was officially participated, the cars of each factory were kept confidential. Wang Erzhu could guess the general situation, but it was impossible to accurately determine the specific model.
"The power of the truck is not as big as possible," said Qin Zhenhua: "After all, even if the army does not pay attention to economics, it will also pay attention to actual needs. There may be multiple versions of their power system. If they want to go to the plateau,
It is definitely better to have more motivation."
Wang Erzhu nodded. The demand for the plateau is also very important in the army. Their car actually takes into account the demand for the plateau.
"Our motivation can also be improved at any time, and there is no need to make any changes, just adjust the ECU." Wang Erzhu said: "If they really compare power, we are not afraid."
With the advancement of electronic technology, the power adjustment of the car is becoming more and more convenient. Just connect the computer to the data cable and then adjust the car's ECU to increase the power.
In society, some people like to brush cars, just to use this method to increase their power. However, civilian cars are not just a casual way. After all, more fuel is used to produce more power by injecting more fuel into a car, but at the same time, it will also
It brings harm to the internal structure of the engine, and the cylinder piston connecting rod may not be able to withstand it. Radical increase in power may lead to a cylinder explosion.
Wang Erzhu can easily increase power because their engine has enough strength to increase power at any time.
"Yes, there is no problem with the power improvement. The key is that the transmission system must be matched well. If they use a high-power engine, it will also be a huge challenge to their transmission system."
AMT transmission is made by adding a set of automatic control components based on the traditional transmission. This transmission is very low in cost and durability is OK, so it can be used on medium-sized trucks, but heavy duty
Vehicles have to use a torque converter. Their own car has a huge torque converter radiator to improve the durability of the transmission.
There is no problem with matching the transmission system, but other factories may not be able to handle it.
Wang Erzhu and Qin Zhenhua were carefully discussing the bidding plan for the next time, and at the same time, other factories were also busy.
In the factory building of the old base factory, a heavy military truck has been assembled. From the appearance, it is not much different from the 977 truck in the United States. It is almost made of the same mold. In fact, they just copied it.
Anyway, time is tight, they have not developed a brand new cab, and just take over the advanced truck structures from abroad.
However, the internal structure of their cars is done by themselves. After all, the army will not accept it if they cannot purchase imported parts.
"It's finally made, and it can catch up with our bid." Yuan Ming, the responsible engineer, said: "We must not lose in this regard. The first heavy military vehicle in China was made by us. We are
First!"
Back then, the country lacked special artillery tractors. The old factory invested all its energy and quickly developed the Yan'an-250 to solve the problem of domestic guns but no cars. After that, their cars were the first to be heavy vehicles.
one.
Now, as the new generation of heavy truck bids for the army are about to begin, they must not fall behind.
"But, we are one step late after all. I heard that Beiben Factory has completed all the test projects of their prototype car and is in service at any time. Our car has just been built and has not been tested yet.
