"Overall, the conference was held very successfully. After this competition, our Beiben truck received a lot of orders, especially the troops stationed in Tibet. The transportation team planned to purchase our vehicles in large quantities
After their initial trial, we were very satisfied with the performance of our car." Wang Erzhu said to Qin Zhenhua.
Qin Zhenhua was quite interested in the whole competition, but there were still many things in the factory, so Qin Zhenhua didn't go over and take a look. Now, after hearing Wang Erzhu's introduction, Qin Zhenhua was quite satisfied. As for the new issue
The supplementary issue of Tank Armored Vehicle Magazine has also been put into Qin Zhenhua's hands. Looking at those vehicles, some even Qin Zhenhua didn't know much about it. Now, seeing these developments, Qin Zhenhua is very satisfied with it: "It seems that
, Our research and development this time is quite marketable."
With the continuous improvement of the domestic transportation environment, road conditions are getting better and better. Therefore, domestic transportation vehicles are gradually developing towards heavy duty. The cars that were originally built in trucks are also developing towards heavy duty vehicles, while the cars of the first machine factory are
The branch factory was originally used to manufacture heavy trucks, but now, the transformation to medium trucks will make many people a little puzzled and feel that there is no market here.
However, the first-machine factory did this. As it turns out, there is still a market. Now, the troops stationed in Tibet have opened up the market. In the plateau, some private transportation departments will also use the first-machine factory's vehicles.
If you are interested, in this way, the Chinese card market of the One-machine Factory opened.
Of course, this is also a mismatch competition. The 260-horsepower engine and nine-speed gearbox were used to be heavy truck configurations. Now they are all used in medium trucks. It can only be said that the development of truck technology is changing with each passing day.
Many technologies are aging rapidly.
At this time, hearing Qin Zhenhua's approval, Wang Erzhu continued: "At the same time, we also saw the prospect of military off-road heavy trucks, so we want to try it once."
Hearing Wang Erzhu's words, Qin Zhenhua's expression became serious: "Have you thought about it?"
"Yes. We decided to develop our own heavy-duty off-road vehicles based on the American HEMTT, Heavy Expanded Mobility Tactical Truck, which is a heavy-duty expandable motor tactical vehicle. We know that there is great competitiveness here, our previous ones
Beiben Heavy Truck does not have much technology to use, but we are confident in it." Wang Erzhu said to Qin Zhenhua: "We have set basic standards."
Now, the army has not yet made specific requirements, and Wang Erzhu actually said that they have formulated basic standards. Of course, these standards are based on the prototype vehicles of the United States.
After hearing Wang Erzhu say this, Qin Zhenhua nodded: "Then let's talk about it."
This time, Wang Erzhu came to report to Qin Zhenhua, of course he wanted to introduce the research and development of this car. If Qin Zhenhua agrees, then start the project completely.
"First of all, the first point is that we need an armored cab. This kind of cab must be able to block the direct shooting of light weapons, so that we can deal with complex battlefield environments. At present, seeing the Americans patrol in desert areas, it is urgent to go to
This kind of thing is needed." Wang Erzhu began to introduce it. Building an armored cab is their strength. After all, the first machine factory is to make military armored vehicles and tanks.
Qin Zhenhua had no doubts about this request and nodded.
"The second is that we plan to adopt a mid-engine solution and a flat-head cab, which can reduce the total length of the car." In terms of central card, Jiefang Factory has planned to use a long-head cab, which can increase the safety of the car
However, on heavy vehicles, long-headed layouts cannot be used. Even if the United States is full of heavy trucks with big noses, their heavy military vehicles use flat-headed cabs.
This is nothing. After all, all domestic trucks have transitioned to flat heads, and the automobile branch of the Yimai Factory also has these experiences, which is not a very complicated matter.
"The third is to be equipped with independent suspension, which is also a must-have for improving the mobility of the car." Wang Erzhu continued.
Independent suspension is much more complicated, and many of them, such as key shock absorption systems, may also need to be transplanted from wheeled infantry fighting vehicles, which are nothing.
Qin Zhenhua continued to nod. These technologies may have many challenges in other factories, but the one-machine factory can solve them.
"Is there any more?" Qin Zhenhua asked.
"In the end, we plan to use an AT gearbox." Wang Erzhu said.
When Qin Zhenhua frowned when he heard him say this.
Most heavy trucks are manually driven. A skilled driver can skillfully switch gears without even stepping on the clutch. This is also to save the life of the precious clutch. As for the heavy trucks that are automatic, most of them are
AMT's transmission is actually a set of electronic control units based on the manual transmission. At present, the first-machine factory is also developing this technology, which can even be matched with a car with 500 horsepower.
This is also considered to be the most suitable automatic transmission technology for heavy trucks. Even the automatic transmission of Mercedes-Benz factory is used in this way.
As for the AT gearbox, it is completely different. It does not have a clutch and uses a set of torque converters to transmit the engine's power. Because there is no hard connection, it is very stable and there will be no impact of shifting gears. At the same time,
It also costs fuel because there is no hard connection. It is currently mainly used in passenger cars, but it is hard to use in commercial vehicles, because for drivers, fuel saving is very important.
"We have studied that although we have the technology of AMT transmission, heavy off-road vehicles may drive in complex terrain for a long time, so that the clutch may overheat. On the mid-card, we can increase the size of the clutch by enlarging it.
The area of the friction plate is improved, but when it comes to heavy vehicles, this is unsolvable. We cannot leave hidden dangers to the army. We must take out the most mature things." Wang Erzhu said.
"The most mature one? You should know that we need to start from scratch. How long does it take to develop such a gearbox, how much money it will cost, and how much price it will cost?" Qin Zhenhua asked.
"We don't think it will cost too much, just transplant the gearbox on our tank." Wang Erzhu said.
This answer made Qin Zhenhua stunned. Yes, why didn’t he expect that the first-machine factory had spent a lot of energy and had successfully developed an automatic transmission for tanks!
