Chapter 406 Low-cost automatic transmission
After considering it, Lao Liu finally felt that he still needed to help, but helping is one thing, and how strong the help is, it is another matter.
"It's easy to borrow someone," he thought it through. Lao Liu quickly made up his mind and laughed through the phone. His voice was very cheerful. "But Mr. Lin, we don't have enough staff here. Zhaoyang's subsequent models are being developed. I can only support you at most 10 people. If there are more work on our side, we will be affected."
The sales of Zhaoyang s5100 are not very good, so you have already started to develop subsequent models? Lin Zheng was a little suspicious of Lao Liu's words, but no matter what, Lao Liu always didn't help him with more and less. He wanted to accept this favor and nodded with a smile, "Yes, then I'll thank you... I'll return it to you in half a year, okay?"
"This is fine," Lao Liu smiled. Since the person has been given, half a year or three months, is it very important to do it? But when he said this, his heart suddenly moved, "By the way, Mr. Lin, in this way, I will add 5 people to you, and you can help us bring some people out?"
Is this using Lianchuang Technology as Lenovo's laptop designer training base? Hearing this, Lin Zheng was amused and crying, but Lao Liu had just sold him such a big face and it was really inappropriate that he would not agree. He had to smile bitterly, "This is easy to say, but I also said it in front. Mr. Liu, this person cannot be too many."
"It's easy to say, you can't delay your work." After calculating Lin Zheng with his backhand, Lao Liu felt very happy.
Damn it. I was plotted against someone. When I hung up the phone, Boss Lin was very upset. He smacked his lips and shook his head. Lin Zheng touched the phone and asked Lang Xuan to call him back. However, after hesitating for a moment, he decided to forget: Lang Xuan's sleep has always been bad, and it is difficult to fall asleep after being woken up at night. Let's talk to her before she gets up.

"Boss, time is a bit rushed, so I found these few." Waldgard said carefully.
Waldegard has good work efficiency. He was able to find four Fujitsu laptops in such a short time. In this era when people did not play the "Sea of Machines" tactic, Fujitsu is another manufacturer that insists on its own design and production. The number of products placed on the market is relatively small. Waldegard is able to find four laptops with different configurations for himself in such a short time, which is already good at finding four laptops with different configurations.
"No," Lin Zheng said. There are three or four machines that are enough to "reference" for themselves. Boss Lin was very satisfied with Waldegard's work efficiency and signaled casually, "Put the computer there... I'll ask, is it possible to improve the continuously variable transmission used on motorcycles and transplant it to our samartcity?"
Waldgard was as if he was struck by a muffled lightning and was stunned.
After receiving Lin Zheng's call, he was thinking about what the boss was looking for himself. But he never expected that the boss was looking for him to find him. Transplanting the continuously variable transmission on the scooter to the car? What did he think?!
"This... is probably not possible?" Waldgard said for a long time, "The continuously variable transmission used on motorcycles uses belt transmission, and the CVT transmission used on cars is steel belt transmission... Can this belt transmission withstand such strong power and torque?"
Anyone who really knows a little about automotive power technology knows that in automotive technology, matching the engine and the gearbox is a very difficult debugging work. The transmission has very high requirements for the power, torque and speed input of the engine. It is easy to say that motorcycles are good, but the power of the automobile engine is strong. In order to ensure the power transmission efficiency, the cvt gearbox... is actually a continuously variable transmission... The internal power transmission uses steel belts, and it is not necessary to use steel belts, but if a belt is used, the huge power is likely to directly tear the belts off.
But Lin Zheng has his own reason, "CVT cars are basically over 100 horsepower, and only steel belts are used, but our samartcity weighs only 800 kilograms. It should be no problem to customize a reinforced belt? ... High-power ATVs, farmer cars and motorcycles use continuously variable transmissions. Isn't there too many belt transmissions? If our samartcity can also be improved with the continuously variable transmission on motorcycles, the cost should be lower than manual transmissions, right?"
Hum? Waldgard was stunned again: he had never thought about this direction.
The weight of the samartcity car has been basically determined. The weight of the two-seat version is approximately between 670 kg and 720 kg, and the weight of the four-seat version is approximately between 700 kg and 750 kg. This weight is not high. At least the materials are much more useful than the Japanese who "save as much as possible".
On the one hand, the car's weight is small. On the other hand, for all-terrain vehicles with a slightly higher grade and an exhaust volume of more than 500ml, which one has a curb weight not above 500kg? It also uses a continuously variable transmission.
What is particularly important is that in later generations, which all-terrain vehicles that use VCT transmissions, are not stronger than the current 798cc engine? They also use CVT transmissions with belts as the transmission body? The power and torque are much more powerful than this, although they are manual... Oh, to be precise, the foot transmission, and the power transmission between the gearbox and the rear wheels also use belts.
This is enough to show that the power transmission body of a belt is actually OK. The belt is not that delicate. There is no problem with the belt continuously variable transmission of the all-terrain car and heavy cruiser. Why can’t a city-based scooter use CVT? This makes no sense!
What? You said that the continuously variable transmission on motorcycles does not have reverse gear? Is it difficult to add an n-speed and r-speed to the CVT transmission for motorcycles? The p-speed is just a locking mechanism. Which all-terrain cars on the market that cost more than $8,000 will not have reverse gear? Designing a reverse gear on the continuously variable transmission is not difficult at all.
The boss didn't say this and he didn't realize this problem. Now that he heard from the boss, Waldgard really feels a little strange: Yes, the power of samartcity is only so small, why can't we improve a motorcycle with a continuously variable transmission installed on samartcity? It's amazing that it's a performance-enhanced type!
As an expert who is proficient in engine and gearbox technology, Waldgard immediately made his own judgment: "Technically speaking, it is no problem. The cost is lower than that of ordinary CVT and manual transmissions. There are only two problems. One is that the belt has a service life, and the other is the belt transmission efficiency."
Lin Zheng agrees that the continuously variable transmission shifts smoothly, or it can be said that this kind of transmission has no gear at all. This is an inherent advantage of this kind of transmission, but its disadvantages are also obvious. The transmission efficiency is not high in the starting and acceleration stages, and belts/steel belts are more likely to slip. This disadvantage is not very obvious in lightweight motorcycles, but it is more serious in cars with heavier bodies: cars with CVT gearboxes start at a slow start. Considering that the samartcity engine has only 36 horsepower, even if the body is light, it is probably more than a "slow" to describe it when starting.
"Then optimize the engine's power output curve and adjust the ratio of Prieli Disk and Prieli Beads, and optimize the starting performance." Lin Zheng used his poor instructions on the continuous transmission of motorcycles to give Waldgard... The weight of Prieli Beads has a decisive impact on the acceleration and extreme speed of the motorcycle, but is it the heavier the Prieli Beads, the faster the acceleration, or is the lighter the Prieli Beads, the faster the acceleration of the car?
Later generations, the large-displacement scooters led by Honda Silver Wing 600, Yamaha T-max500 and Suzuki Tianlang 650 have been proposed by these three motorcycle manufacturers. The maximum displacement scooters that can be seen on the market are only 250cc. At this moment, Lin Zheng missed his boy who likes to play heavy pedals... He bought a parallel silver Wing 600 for more than 50,000 yuan, and specially spent 3,000 yuan to get a card. Unfortunately, he was not found out by the traffic police, but he was ridden for less than three days and was taken away by the thief.
Faced with such a boss who has only a slight understanding of motivation, Waldgard's mouth twitched violently, "It's a solution."
His own method was feasible, which made Boss Lin feel a little proud, but he still didn't forget that this was somewhat strange. He had to give Waldgard a reminder, "Let's ask first if there is any regulation that the US government does not allow the transplantation of continuously variable transmissions such as motorcycles to cars. If not, let's do it. In the future, it will be used specifically on this kind of light vehicle. If there is one, forget it."
"Okay." With the boss's words, Waldgard finally breathed a sigh of relief: Just now, what he was worried about was actually this problem: Is there any restrictions on the terms and conditions of the continuously variable transmission in the government? No one has ever thought about transplanting the continuously variable transmission on motorcycles to light cars?
