But there is a very criticized problem with the Soviet gearbox design, that is: the manual gearbox is very well designed, very good! When it came to the design of automatic transmissions, Soviet car designers were a bit of a tiger biting a hedgehog -- they couldn't get to know it.

At the beginning, the company assigned three research tasks to the transmission project research team: the development of a five-speed manual transmission, a six-speed manual transmission and a four-speed automatic transmission. Nowadays, the development of five-speed manual transmission and six-speed manual transmission has been successful, and according to the analysis of Xiao Chenxi and Alice, the performance is also very good, the delay between shifts is very low, almost comparable to those quasi-professional event-level special gearboxes, and the feeling of shifting gears is very smooth and gentle, and it will not be like the current gearbox that has not changed the gear you want for half a day. What is even more difficult is that the cost of such an excellent gearbox did not rise much, and in this regard, the strength of the Soviet gearbox designers was really strong.

Zhang Lan even thought, can we say that these two manual transmissions are promoted to the international modified car and mid-to-high-end sports car market? After all, the international quasi-professional event-level gearboxes are quite expensive, and they are still priceless, and they may not be able to buy them if they want to! The mid-to-high-end sports car is equipped with a manual gearbox that is not as good as the performance of these two gearboxes, well, it is a problem that can be considered.

Compared to the achievements of manual transmissions, these guys have been a bit blind in the design of four-speed automatic transmissions, and have only produced a less successful sample so far, and often have inexplicable failures, such as the ability to suffocate the engine at idle.

That's not going to work! Zhang Lan was a little depressed, automatic transmission as the trend of the development of later generations of automobiles, in civilian cars, now automatic transmission has gradually begun to encroach on the territory of manual transmission.

Even when Zhang Lan was reborn, in the field of civilian vehicles, automatic transmissions are no longer the patents of high-end cars, hundreds of thousands of cars equipped with automatic transmissions abound, and manual transmissions with better performance and better fuel economy have become the choice of low-end cars or low-end models of intermediate cars. The automatic transmission model has become the first choice for most high-end models, and even in the more than 200,000 intermediate car market, you can see a five-speed automatic transmission or even a six-speed automatic manual transmission.

Of course, sports cars are an exception, even on supercars like Ferrari and Lamborghini. The most common thing to see is the manual gearbox, the smaller shift delay can make the shift time shorter, and even in F1 cars, the manual transmission is chosen, just to change the gears to manual paddle shifters in order to change gears more quickly.

Originally, I was going to use a manual transmission to play a low price. The more comfortable automatic transmission is mainly aimed at high prices, but now the mature automatic transmission has not yet been made, what can be done?

The reason why the manual transmission is chosen is because the human brain is always more flexible than the reaction of the machine, and knows when to take the most appropriate action and gear to achieve the most desired effect.

Well, it's a pity that although the manual gearbox is the most suitable reaction for people, people are always lazy, and even the action of shifting gears will be troublesome; It's a pity even more. The powerful frustration of a manual transmission shift is disliked by many people, especially the rich people who are full of brains; The most undesirable thing is that these people are still the main force of the high-end car buying group.

In order to take care of these guys who are very much focused on enjoyment, the automatic transmission was born, well, the automatic transmission shifts very smoothly, as long as you put on the D gear, the car will run forward when you step on the accelerator, and the car will slow down when you close the throttle, even if you slam on the accelerator. And there will be no such sharp acceleration feeling as in a manual transmission, and a very foolish way of operation will definitely not let you find the unique frustration in a manual transmission.

Zhang Lan doesn't like automatic transmissions, and always feels that automatic transmissions have degraded people's heads. But the market likes it very much, Zhang Lan's small arms can't resist the thighs of the market, and in the end she can only bow to the market helplessly.

"How long will it take for you to get this automatic transmission?" Xiao Chenxi asked Xie Liaosha, the chief designer of the gearbox, anxiously.

"It's hard to say," Seryosha shrugged helplessly, he was equally distressed by the question, "We've never designed an automatic transmission before. It's just some theory, but the difference between theory and product is too great, and I don't dare to say when we will be able to develop an automatic transmission that can be fully practical. As he spoke, he lowered his head and muttered to himself, "It would be nice if there was an automatic transmission for us to refer to, even if it was a simple design drawing!" ”

Overheard Seryosha's words, Zhang Lan almost sweated to death: the design drawings of the gearbox are much more expensive than the gearbox, and all the design parameters will be shown on the drawings, and there are cars equipped with automatic transmissions, but which car do you see that comes with the design drawings of the gearbox?

Drawing? Have an automatic transmission as a reference? Zhang Lan was suddenly stunned: Doesn't there be several automatic transmissions in my company! The two bulletproof Mercedes-Benzes of his parents, as well as the gearboxes on the Mercedes-Benzes of Li Xiushui and Li Mingjiang, are not all automatic transmissions?

Quietly pulling Xiao Chenxi aside, Zhang Lan asked in a low voice: "Sister, if there is an automatic transmission in front of you, can you depict its various designs and parameters?" ”

Xiao Chenxi was also worried about this problem, and when she heard Zhang Lan's words, her eyes suddenly lit up: "Of course there is no problem, scanning is our forte," but as he spoke, a beautiful little face fell, and his small mouth flattened, "The question is where do we go to get an automatic transmission?" ”

Hey! Really! Zhang Lan was excited: What, thank you Mercedes-Benz, thank you for your contribution to me, and I will find a way to compensate you when I have the opportunity in the future.

"You forgot," Zhang Lan smiled and reached into Xiao Chenxi's armpit to tickle her, "Isn't there several Mercedes-Benz in our company, all of which use automatic transmissions, if you can, you can scan one, and then give them the drawings for reference!" ”

"That's right! I didn't think of that! Xiao Chenxi snorted happily, and suddenly realized that there was something wrong with her actions, but this was in the company: turn around quickly, fortunately, no one noticed her, and she was finally relieved, and then patted her chest with some fear.

"And how far can your scan go?" Zhang Lan asked a little uneasily.

"It can be exactly like their blueprints!" Xiao Chenxi is full of confidence.

"Hmm." Zhang Lan nodded, Xiao Chenxi said this, she had nothing to worry about.

After calming down a bit, Xiao Chenxi came to Seryosha and asked, "If there is a design drawing of an automatic transmission for your reference, you can quickly come up with results?" ”

"Of course, with a reference, we will soon be able to design a qualified automatic transmission!" After speaking, hearing Xiao Chenxi ask, Xie Liaosha suddenly moved in his heart: Could it be that the company already has a design drawing for an automatic transmission? Thinking so in his heart, he couldn't help but ask, "Since the company has a design plan for automatic transmissions, why not use this plan directly?" Instead, you have to redesign it? ”

"You shouldn't ask, don't ask!" Xiao Chenxi glanced at Xie Liaosha coldly, didn't give him a good face, and his tone was so cold that he could freeze a living person to death, "In addition, you should let you know, the company will naturally tell you; You shouldn't know, and you don't have to ask. ”

Xiao Chenxi's cold tone made Seryosha instantly have an illusion, as if he was facing an iceberg at this moment. made Seryosha shudder, and he didn't dare to say more.

didn't dare to say it, but it didn't delay Xie Liaosha secretly wondered in his heart: Could it be that the company's commercial spies stole the design plan from other companies? Well, yes, that's all it can say!

"Very good," Xiao Chenxi nodded, her tone still cold, "The design drawings of this gearbox will be given to you tomorrow." Remember that you can only refer to it, and you must not copy it all! If, at the end of the gearbox acceptance, you find that your design is exactly the same as the reference design drawings for you, you can all go back to your hometown in Russia! ”

With Xiao Chenxi's words, Seryosha affirmed his conjecture even more: it must be the design drawings obtained by the company from other companies, and the reason why they can't all be copied is very simple, it must be worried that they will be found out, so it will cause disputes!

Thinking like this in his heart, Seryosha had to nod hurriedly, "Don't worry, boss." As long as we have a reference, we guarantee that we will be able to produce a qualified automatic transmission sample within three months. ”

Several design departments of the car company have completely inspected it, although the effect is not satisfactory, but it is acceptable, after all, these guys have not designed anything new since the eighties, and they can have today's results, or their previous foundation, but it seems that tomorrow will be the time for Petrovich to hand over the engine design plan, I don't know what this guy is doing now?

Now that they had the object of the scanning, the three of them had no intention of continuing to inspect - the inspection was almost done - they returned to Zhang Zongjun's office, asked for the key to Zhang Zongjun's bulletproof Daben, and waited for Zhang Zongjun to ask what was going on, and slipped down directly.

These three children, what do they want to toss this time? Looking at the three figures who had already walked out of the door, and then thinking about what kind of bullying his cute Mercedes-Benz might suffer again, Zhang Zongjun shook his head and forced himself not to think: the more he thought about it, the more uneasy he became, and it was more important to hurry up and work.

PS I have to squat in the Internet café for a day, and tomorrow the Electric Power Bureau will do it, alas, the people in the Internet café are really noisy. Why are so many little guys arguing inside, I finally understand after thinking for a long time that the students are on vacation!

It's noisy, so it's not well written, please forgive me, I don't know what I'm writing in a daze, but it's good every day. (To be continued, if you want to know what will happen next, please log in to the www.qidian.com, more chapters, support the author, support genuine reading!) )
