After thinking about it, Lao Liu finally felt that he still had to help with this favor, but it was one thing to help, and how hard he helped was another matter.

"Borrowing people, it's easy to say," thought clearly in his heart, Lao Liu quickly made up his mind, laughed over the phone, and his voice was very hearty, "But Mr. Lin, we don't have enough manpower here, Zhaoyang's follow-up model is being developed, and I can only support you for 10 people at most, and any more work on our side will be affected." ”

The sales of Zhaoyang S5100 are not very good, and you have already begun to develop follow-up models? Lin Zheng was very skeptical of Lao Liu's words, but no matter what, Lao Liu always helped himself a little bit, and he wanted to admit this favor, so he nodded with a smile, "Cheng, then I thank you...... I'll give it back to you in half a year, right? ”

"That's no problem," Lao Liu said with a smile, since the person has already sent it over, does it matter if it is half a year or three months? But when he said this, his heart suddenly moved, "By the way, Mr. Lin, in this way, I'll add 5 people to you, and you can help us bring some people out by the way?" ”

Is this Lianchuang Technology used as Lenovo's laptop designer training base? Hearing this, Lin Zheng couldn't cry or laugh, but Lao Liu had just sold himself such a big face, and it was really inappropriate for him not to agree, so he had to smile bitterly and said, "This is easy to say, but I also said it in front, Mr. Liu, this number can't be too much." ”

"It's easy to talk about it, but you can't delay your work." calculated Lin Zheng with his backhand, and Lao Liu's heart was very happy.

Nima. was calculated, hung up the phone, Boss Lin was full of unhappiness. Smacking his lips and shaking his head. Lin Zheng touched the phone and was about to call Lang Xuan backhanded, but after hesitating, he decided to forget it: Lang Xuan's sleep has not been good, and it is difficult to fall asleep after being woken up at night, so let's wait for her to get up and then talk to her.

…………………………………………

"Boss, time is a little rushed, just find a few of them." Waldegard said cautiously.

Waldegard is working well. In such a short period of time, it was possible to find 4 Fujitsu laptops, and in this era when everyone did not play the "sea of machines" tactics, Fujitsu is a manufacturer that insists on its own design and production. The number of products on the market is relatively small, and Waldegard was able to find himself four notebooks with different configurations in such a short period of time, which is already a good ability.

"Not bad," Lin Zheng said. There are three or four machines, which are enough for your own "reference". Boss Lin was very satisfied with Waldegard's work efficiency, and casually motioned, "Put the computer over there...... I asked, is it possible to improve the continuously variable transmission used on motorcycles and transplant it to our Samartcity? ”

Waldegard was like a bolt of thunder on the head, and he was dumbfounded.

After receiving Lin Zheng's call, he was wondering what the boss was looking for him. But he didn't expect that the boss would find himself this problem. Transplanting the CVT from the scooter to the car? What did he think?!

"This ...... I'm afraid not, right? Waldegard was dumbfounded for a long time, and then Ai Ai said, "The continuously variable transmission used on the motorcycle is belt driven, and the CVT transmission used on the car is steel belt driven...... Can this belt drive withstand such a high level of power and torque? ”

People who really know a little bit about automobile power technology know that in automotive technology, the matching of the engine and the gearbox is a very difficult debugging work, and the gearbox has quite high requirements for the power, torque and speed of the engine input...... In fact, it is a continuously variable transmission...... The internal power transmission uses a steel belt, not necessarily a steel belt, but if a belt is used, the huge power is likely to tear the belt directly.

But Lin Zheng has his own reasoning, "There are many cars with CVT and a displacement of more than 2.0, basically more than 100 horsepower, and the weight is rarely less than 1.2 tons, so the steel belt is used, but our Samartcity weight is only 800 kg, and it should be no problem to customize a reinforced belt, right?" …… Isn't it true that high-power ATVs, farmer bikes, and motorcycles are equipped with continuously variable transmissions and belts? If our Samartcity can also be improved with the continuously variable transmission on the motorcycle, the cost should be lower than the manual transmission, right? ”

Well? Waldegard was stunned again: he hadn't really thought in that direction.

The weight of the Samartcity has been basically determined, the weight of the two-seater version is between 670 kg and 720 kg, and the weight of the four-seater version is between 700 kg and 750 kg.

On the one hand, the weight of the car is small, on the other hand, those all-terrain vehicles with a slightly higher grade and an exhaust volume of more than 500ml, which one has a curb weight of more than 500kg? The same uses a continuously variable transmission.

What is especially important is that the all-terrain vehicles that use VCT gearboxes in later generations are not more powerful than the current 798CC engine, and do not also use CVT gearboxes with belts as the transmission body? The large displacement cruising motorcycles, represented by Harley, which have a displacement of 1.5 to 1.8 liters, are much more powerful in power and torque, although they are manual...... Oh, and the foot gearbox, to be exact, also uses belts for power transmission between the gearbox and the rear wheels.

This is enough to show that the belt as the main body of CVT power transmission can actually be, the belt is not so delicate, all-terrain vehicles and heavy-duty cruisers use belt continuously variable transmission is no problem, why a city scooter with CVT is not good? It doesn't make sense!

What the? You say that the CVT on a motorcycle does not have reverse gear? Is it difficult to add an N and R gear to a CVT gearbox for motorcycles? The P gear is just a locking mechanism, and which of the all-terrain vehicles on the market that cost more than $8,000 does not have a reverse gear? Designing a reverse gear on a continuously variable transmission, there is nothing difficult about this problem at all.

The boss didn't say this and didn't realize the problem, but now listening to the boss say this, Waldegard really felt a little strange: yes, the belt even Harley's torque is 100 Nm. The engine above the meter can withstand it, and the power of the Samartcity is only so little, why can't it be improved to install a continuously variable transmission on the Samartcity for a motorcycle? It's amazing, it's a performance-enhancing one!

As an expert in engine and transmission technology, Waldegard immediately made his own judgment: "Technically, there is no problem, the cost is lower than that of ordinary CVTs and manual transmissions, there are only two problems, one is the service life of the belt, and the other is the transmission efficiency of the belt." ”

Lin Zheng agrees with this, the continuously variable gearbox shifts smoothly, or so to speak, this kind of gearbox has no gear at all, which is the inherent advantage of this kind of gearbox, but the disadvantages are also obvious, the transmission efficiency in the starting and acceleration stages is not high, the belt/steel belt is more likely to slip, this shortcoming is not very obvious on lightweight motorcycles, but it is stricter on heavier cars: cars with CVT gearboxes, the start is always slow. Considering the Samartcity engine, it only has 36 hp and 60 Nm. The power output of meters, even if the body is light, I am afraid that it is not just a "slow" can be described at the start.

"Then optimize the power output curve of the engine and adjust the ratio of Puli disc and Puli bead, and optimize the performance of the start." Lin Zheng gave Waldegard instructions with his pitiful instructions on continuously variable transmissions for motorcycles...... The weight of Pulizhu has a decisive impact on the acceleration and top speed performance of the motorcycle, but is it the acceleration faster the heavier the Pulizhu, or the acceleration of the Pulizhu is faster than that of a lighter car?

Later generations of large-displacement scooters led by Honda Silver Wing 600, Yamaha T-MAX500 and Suzuki Tianlang 650 I don't know if they have been proposed by these three major motorcycle manufacturers, and the largest displacement scooter that can be seen on the market is only 250CC displacement...... More than 50,000 bought a parallel silver wing 600, and deliberately spent 3,000 oceans to set a card, but unfortunately, it was not found by the traffic police uncle, but it was only ridden for less than three days and was taken away by the thief.

Faced with such a boss who knew little about power knowledge, the corners of Waldegard's mouth twitched fiercely, "It's also a way." ”

His own method turned out to be feasible, which made Boss Lin feel a little proud, but he still didn't forget that this matter was a little strange, and he had to give Waldegard a word of advice, "Let's inquire first, does the U.S. government have regulations that prohibit the transplantation of this kind of continuously variable transmission on motorcycles to cars, if not, we will do it, and it will be used exclusively on this kind of light vehicles in the future, if there is, forget it." ”

"Okay." With this sentence from the boss, Waldegaard finally breathed a sigh of relief: just now, he was worried about this question: are there any restrictions on the government side regarding the continuously variable transmission? Transplanting a continuously variable transmission from a motorcycle to a light car, no one thought about it at all, right?

Just when he was in a trance, Lin Zheng's voice sounded again: "By the way, I heard that the Japanese K-CAR has begun to apply CVT gearboxes, you can ask what is going on by the way." (To be continued......)
