Chapter 610 Ways to Improve the Performance of Heavy Trucks
At the dinner table, Zhao Guoyang's straightforward words made several senior executives of the FAW Group present feel a little embarrassed.
Wu Jianlong, who was originally complacent about his factory's product "Jiefang J3" and the "Dongfeng Tianlong" that defeated the rival Second Automobile, was even more red.
But there is no way, please ask Zhao Guoyang to tell that he proposed it, and he can only bear it silently at this time.
Glancing at the embarrassed look on Mr. Wu's face, Zhao Guoyang was secretly amused in his heart.
To be honest, his original intention was not to hit Chairman Wu and these high-level executives of FAW, but compared with the island country Foton Auman GTL, the two highest-end heavy trucks in China have a relatively large gap in performance.
Of course, Zhao Guoyang said so much, not just to belittle domestic products, he naturally has his own intentions in it.
After Wang Shouyi and Mao Feiming almost digested their own stories, Zhao Guoyang changed his words and said: "In the short term, on the whole, it is difficult for our domestic heavy trucks to catch up with the international advanced level. However, it is not impossible to make breakthrough improvements in some important performance areas. ”
Speaking of this, Zhao Guoyang looked at Mao Feiming and said: "Mr. Mao, the heavy trucks you need for the 'Second Construction of the Beijing' are basically transported to and from the surrounding areas of the capital, right?"
Mao Feiming was stunned for a moment, and then nodded again and again: "Yes, yes, yes, that's right! The projects that our 'Second Construction' received are basically within the scope of the capital, and there is rarely a need to travel long distances." ”
"Researcher Zhao, what do you mean by asking this?"
Zhao Guoyang explained with a smile: "It's not interesting, I just want to help you save some money!"
As soon as he heard the word "save money", Mao Feiming's eyes immediately lit up.
This blurted out: "Researcher Zhao, please give us 'Erjian' guidance, I am grateful."
Listening to the words of this Mao Zong who was a little out of shape, Zhao Guoyang was a little speechless.
He couldn't say this, so he could only cough and say: "I also said when I gave an example just now, the performance of heavy trucks is mainly judged from starting, acceleration, braking, noise, climbing, fuel saving, tug-of-war, cab static, etc. ”
"Starting, acceleration, fuel saving, etc., which are related to the performance of the engine and transmission, this point, our domestic products have not been able to make much changes for the time being. ”
"As for the noise and cab static, it also requires a more refined process, and we can't make big changes immediately, so we can only aggrieved the driver to overcome the difficulties. ”
"There is also the climbing performance of the vehicle, just Mao also said, at least your 'second construction' in this regard, is not too high requirements. ”
After Zhao Guoyang finished speaking, he didn't forget to glance at Mao Feiming inquiringly, and saw that this Mao boss nodded again and again.
"In this way, the key to the problem is the 'braking'. As long as our domestic heavy trucks solve the problem of 'braking', or make relatively large improvements, then they can meet the requirements of your 'second construction', isn't it?"
Mao Feiming was slightly stunned, nodded a little uncertainly, and said, "Well, the truth should be like this." But in general, imported heavy trucks are still our first choice after all......"
Hearing this, Zhao Guoyang is Yile: "Mr. Mao, if your first choice for 'second construction' is imported heavy trucks, it will cost two or three times more money." ”
"The single price of this heavy truck is not cheap, a Foton Auman GTL is about 400,000 or 500,000 yuan, is Mao really ready to 'Erjian' the current heavy truck gap, all with this car to make up? That price is not small!"
Although Zhao Guoyang's words are straightforward, the truth is not bad at all.
Mao Feiming already knew the straightforward nature of this "Researcher Zhao" at this time, and he was not angry at the moment, but nodded sincerely: "Researcher Zhao, what you said is also reasonable, at least in the past two years, our 'second construction' has not yet adopted the strength of 'all imported' on heavy trucks." ”
Zhao Guoyang gave a thumbs up and said with relief: "I admire that Mao can always tell such a big truth!"
"Actually, I may have heard what I mean. In my opinion, as long as the domestic heavy truck makes some improvements in the 'braking' problem and narrows the gap with the international advanced level as much as possible, it can be applied to the ...... of most domestic construction sites."
After Zhao Guoyang said this, several cadres of the FAW Group had a flush on their faces.
At this moment, they still don't understand that this researcher Zhao is helping his factory to sell!
Mao Feiming had obviously been persuaded by Zhao Guoyang, and immediately said "hmm": "I completely agree with Researcher Zhao's point of view." It's just that...... Since the 'braking' problem of this heavy truck has existed for so long, it is not so easy to solve, right?"
Speaking of this, Mao Feiming's eyes involuntarily fell on several leaders of FAW Group.
When his eyes met Wu Jianlong, Chairman Wu immediately jumped up and said: "Mr. Mao, you don't have to worry about this at all, with my understanding of Brother Guoyang, since he raised this problem, there must be a solution." ”
Wu Jianlong said as he threw a "begging" gaze at Zhao Guoyang.
Looking at the "pitiful" appearance of this big guy, Zhao Guoyang wanted to laugh in his heart - feeling that Chairman Wu really regarded himself as the "master" of their FAW Group.
"Oh, it's really like what Mr. Wu said, do you already have a solution to the problem, Brother Guoyang?"
When Director Li Ru heard Wu Jianlong's words, he also looked at Zhao Guoyang with interest.
This Director Li spoke, and everyone's eyes naturally turned to him.
In the face of so many pairs of eyes, Zhao Guoyang sat up straight and said calmly: "If you want to change the current situation of our domestic heavy trucks' poor 'braking', there are two ways, the first is to make a fuss about the brake." ”
Zhao Guoyang raised his hand and said: "The general working principle of the braking system is to use the friction between the non-rotating elements of the body or frame necklace and the rotating elements connected to the wheels or transmission shafts to prevent the rotation of the wheels, or the tendency to rotate. ”
"The performance of the brakes is undoubtedly the main factor affecting the braking ability of the vehicle. In this regard, the current domestic automotive brake technology level is still relatively low, even if you work hard, it is impossible to catch up with the international advanced level in a short period of time......"
When Zhao Guoyang said this, there was already silence in the box, and everyone listened attentively to his story, not wanting to miss a word.
After a slight pause, Zhao Guoyang continued to speak: "In addition to the 'brake', there is another factor, which has a great impact on the 'braking performance'. That is the axle load distribution of the vehicle. ”
"Axle load distribution? What is that?" Mao Feiming was an outsider, and asked right away.
Zhao Guoyang made a gesture of "don't be impatient" and slowly explained: "The so-called axle load distribution of the vehicle refers to the vertical load of each axle on the support plane when the vehicle is empty and fully loaded. This data can also be expressed as a percentage of the total mass of no load and full load. ”
"In general, the axle load distribution of a car is an important quality parameter for a car. It has a great impact on the traction performance, braking performance, handling performance and stability performance of the car, and even the service life of the tires. ”
Therefore, when we design the overall body, we must reasonably select the axle load distribution according to the layout form, use conditions, and performance requirements of the car. ”
When Zhao Guoyang said this, Wu Jianlong and several leaders of FAW Group were all bright-eyed.
Indeed, although they are not leading cadres in professional and technical aspects, they still have a certain understanding of the basic performance of automobiles.
Obviously, Zhao Guoyang's remarks are reasonable, and he can't find fault at all.
Wu Jianlong secretly clenched his fists excitedly, staring at Zhao Guoyang intently, for fear of missing something.
On the other side, Director Li Ru nodded in agreement.
He is a professional as the director of the equipment industry department, and he even spent some time in the vehicle research institute below, specializing in the performance of automobiles.
At this time, seeing that Zhao Guoyang found a solution to the problem of "braking" in minutes, he couldn't help but sigh at this young man's flexible thinking and fast reaction.
Unlike Li Ru, Wang Shouyi is ignorant of vehicles.
But he himself is a frequent driver, and he is no stranger to some of the performance of cars.
At this time, listening to Zhao Guoyang's high-minded talk, Director Wang was secretly amazed, and felt that his meal was really worth it.
Zhao Guoyang didn't know what the cadres and CEOs present were thinking, and continued to explain unhurriedly: "When determining the axle load distribution of the car, the designers consider the most about the static direction stability and dynamic direction stability of the car. ”
"Theoretically speaking, the distance from the position of the car's center of mass to the car's neutral steering point has a decisive impact on the car's static directional stability. In other words, this data has the greatest impact on 'braking'. ”
"As long as we make more fuss and carefully demonstrate this data, we should be able to easily improve the braking performance of our domestic heavy trucks. ”
Zhao Guoyang continued: "If you want to consider it in an all-round way, the axle load distribution of our domestic heavy trucks naturally cannot be changed simply for the sake of braking performance." ”
But this road can be said to be a shortcut. In this special period, if we only want to improve the 'braking performance' of our domestic heavy trucks, this road is completely feasible......"
After Zhao Guoyang's words were finished, everyone at the scene sat quietly in their seats and tasted the true meaning.
After a long while, Li Rucai sighed faintly and said, "Brother Guoyang, your idea is really ...... I don't even know what to say about it! In terms of feasibility, there is absolutely no problem!"
Director Li Ru's words can be regarded as a final conclusion for Zhao Guoyang's remarks and a great affirmation.
