Chapter 106 High Power Diesel Engine
“The four-wheel independent suspension used in this car, I think the more common and quite strong double wishbone suspension can be used.”
“Similar to As mentioned just now, although the integral axle suspension has better extreme off-road capabilities, the vehicle's stability is not very good when driving at high speeds, while independent suspension can ensure the stability of the vehicle at high speeds. "
"Of course, using independent suspension will reduce the overall strength of the frame. We need to make some special arrangements in this regard."
Jiang Hui simply picked up a pen from the side and paper, and started drawing quickly.
"Its chassis can use traditional trapezoidal girders. Of course, it needs to be designed to be stronger."
"In addition to the two thick longitudinal beams, five more cross beams are set here. It is also the main means for non-load-bearing vehicles to improve the overall strength of the frame.”
Jiang Hui explained his thoughts while drawing.
Although some things are not innovative technologies, it is just right to bring them over.
This is actually very important.
If a car uses a lot of new technologies, it will definitely encounter many problems during the production and manufacturing process, and the quality stability is also worrying.
On the contrary, if you can use more traditional technologies to combine them to achieve new performance effects, that would be the best.
The "Hummer" Jiang Hui has now developed has this advantage to a certain extent.
“What do you think of its four-wheel drive system?”
As for what Jiang Hui said about the independent suspension, Zhu Jiansheng chose to reserve his opinion and clarify the overall plan first. Say it again.
"We must use a mechanical four-wheel drive system. This four-wheel drive system is essentially a three-lock structure. Its transfer case has a locking function that is equivalent to a differential lock. At the same time, its differential design on the front and rear axles Becomes a lockable Torsen differential, so as long as one tire has traction, the vehicle can continue to move forward." A very large bulge is formed between the two seats. The four members are basically located at the four corners of the cabin when riding, and the distance in the middle is very far.”
“For a civilian car, this is like this. The design of the hood is a huge flaw.”
“But for military vehicles, this bulge is particularly convenient for installing weapons on the roof.”
“Soldiers operating weapons can stand on it. You can shoot freely on this drum kit, and the weapons on the top are not just simple machine guns. You can even install some grenade launchers and heavy machine guns, which are much more powerful than the previous BJ212.”
With Jiang Hui's continuous explanations and some structural sketches, the image of a mighty and fierce military off-road vehicle began to appear in Zhu Jiansheng's mind.
Seeing Weng and his son-in-law discussing military vehicles in full swing, Zhu Lin and Fang Zhen could only whisper secretly beside them, not daring to disturb their thoughts.
“According to your current thinking, we need a high-power diesel engine to meet the needs of this vehicle.”
Zhu Jiansheng quickly thought about the feasibility of producing this new military off-road vehicle. sex.
If you want to propose a project to the Fifth Machinery Department, you must be sure that you can design and produce it.
Otherwise, it’s better not to mention it.
“Didn’t the Department of Thermal Energy and Power Engineering study a 6.5L diesel engine for power use on a certain type of armored vehicle?”
“We can make some technologies on this basis. Improve it so that it can meet the needs of this vehicle.”
“At the same time, we can also cooperate with other domestic diesel engine factories.”
Although the plan was proposed by the Capital Institute of Technology. , but it is impossible for the college to produce all the parts by itself.
Even if the college has its own school-run factory, it can only handle part of the parts production, and most of them still need to find professional supporting factories.
Of course, if the Department of Vehicle Engineering of Capital Institute of Technology can take this opportunity to build itself into a research and development institution and output design plans to various factories, the meaning behind it will be extraordinary. "I will sort out the plan again and communicate with the department heads of several other majors tomorrow to see how to get the project started as soon as possible."
The two talked about it all night At around eleven o'clock, Zhu Jiansheng basically understood Jiang Hui's thoughts.
The only thing left is to formulate these ideas into a specific plan and then submit it to the Fifth Machinery Department to apply for funding.
"The neighbors to the south are very restless. I feel that there will be some military operations in the next six months."
"Dad, it would be very useful to publicize our vision for a new generation of military off-road vehicles before this operation. Necessary. "
"In the future, everyone will be able to appreciate the goodness of these designs after suffering losses. "
Compared with the BJ212, Hummer's performance in all aspects is absolutely superior.
Even if there is no way to produce it immediately, there will still be a lot of practical opportunities after it is produced in a few years.
The key is that this product will definitely have the opportunity to be exported and earn foreign exchange in the future, becoming a leading product in China's automobile industry.
It is even possible to take this opportunity to place a certain automobile factory under the Capital Institute of Technology.
“Speaking of this, isn’t the new generation BJ212 project required to be brought forward?”
“When our new project is launched, will it bring problems to the development of the new generation BJ212? What impact? "
Zhu Jiansheng did not want to have a bad impact on Jiang Hui's development at the Capital Automobile Manufacturing Plant because of his own reasons.
That made him feel guilty.
“Everyone’s positioning is completely different, and it doesn’t have much impact.”
“By the way, I thought of a more appropriate name for this new generation of military off-road vehicles, otherwise Are you going to use it to apply for a project?”
Jiang Hui still has a special liking for the name "Hummer".
Even compared to the "Warrior", he felt that the "Hummer" was more vivid and vivid.
"What name do you want to use?"
Zhu Jiansheng will definitely satisfy this small request.
In fact, according to his idea, what name do you want?
It is directly the same as BJ212, just write a code.
“Hummer! It comes from the meaning of tough wild horse.”
“What we are designing is an all-terrain wheeled off-road vehicle with high mobility. It must be fast enough and have good trafficability.”
“I think the word Hummer is very appropriate. "
Zhu Jiansheng originally thought that Jiang Hui was going to give a name with a special meaning, but he didn't expect that it would end up being "Hummer".
However, he also thinks that the "Hummer" is really good.
“Okay, I will try to submit the project approval report for the ‘Hummer’ next week and start the formal model design work as soon as possible!”
Zhu Jiansheng felt a rare sense of relief and immediately made the decision.
