Era: Retired from the army at the beginning and returned home.

Chapter 122 The Not-So-Successful Tricycle
Luo Cheng came to the auto repair shop. He came relatively early today, but when he arrived at the factory, he found that Team Leader Jiang and the others had already arrived at the factory and were dismantling the water tank of Manager Zhang's jeep. The team's car and team member Li Yiwen were not there.

Seeing Luo Cheng coming, Team Leader Jiang took the initiative to say hello and introduced the current situation.Li Yiwen went to the steel factory to get the hollow round pipe. The thickness problem is not required at present. When the actual installation is actually done in the future, the thickness of the pipe will be specially designed.

Luo Cheng looked at the hand-assembled booster pump. The shell was not painted, but this is a small problem. The main problem is to look at two points. After it is installed, it can be started, and the other is whether it leaks oil.The pressure value can be adjusted through the valve, but if the seal is not good enough to leak oil, everything is useless.

The master welder has been contacted, and he will come over when he officially starts work at the latest.The one who came was a fourth-level welder. If the round iron pipe could not be sealed after welding, there would be a problem with the assessment of this fourth-level worker.

Luo Cheng felt that there was no need to worry about the installation of the booster pump. He was an engineer. He would at most discuss the idea of ​​the installation. After the plan was decided, Luo Cheng had to check on any other steps.

And there is no rush to make the cube car now, the size and model of the chassis material have been designed.Call the headquarters a little later and ask him to contact the higher-level department of the steel factory here, and then it will be awkward to go there, and there is no need to pay, and the steel factory will send the materials Luo Cheng wants.

As soon as the material arrives, arrange for two people to be responsible for cutting it first.The people in the repair shop can do this.As long as the material is cut out, the welders will be called in the next day, not only can the chassis be welded, but even the people in the repair shop can immediately install the bearings and wheels.The iron plates and steel pipes of the car body were also delivered by the steel factory. Once the work started this time, it would not be easy to listen to it, because the cooperation of welders was needed throughout the whole process, and it was not easy for people to come one day and then come back one or two days later.

The manufacture of the cube car has not yet started, Luo Cheng plans to get the side three wheels up.There are also many employees in the workshop who arrive early, and there are more apprentices, or the apprentices themselves come before the masters.They can't wait for their masters if they have something to do, they can only wait for their masters.

Wang Cheng didn't come to work now, but Niu Zi and Dali were already in the workshop.

"Niuzi, Dali, the two little masters are here to help. If Master Wang doesn't need you today, we will set up the three rounds here."

As soon as Niu Zi and Dali heard Luo Cheng's greeting, they came over with a smile.Let's not talk about Luo Cheng's ability. After Luo Cheng came to the factory, the food has improved a lot, and he brought back a few bundles of defective cloth, which are still in the warehouse.This has brought so many supplies for them, it is not just a word to call it helping work.And how could a seventh-level engineer be incapable.

"Group leader Luo~."

"Well, take this gearbox apart for me."

The gearbox is a car gearbox. It is a new product sent by Tianhu. The brand new variable box needs to be disassembled. As an apprentice, at most, I think that this new thing will not be broken when disassembled, but following orders is an apprentice’s master at the beginning. If you don't understand what you teach, you can read more and ask more questions, but don't question others.

The principle of the transmission is also simple. Gears of different sizes are driven to form different speeds, and then cooperate with the throttle power of the engine to form a stronger rotational force.

Cars have three gears, while motorcycles have only one gear. Motorcycles simply rely on the accelerator to make the engine bring more power to control the speed.

Just like a car, if you just put it in first gear, you can actually control the speed by the accelerator, but you can only rely on the speed to drive the overall speed, which is very fuel-intensive and easy to damage.

But now there is only a car transmission, and it is impossible to install a gear shifter on the side three wheels.Now it can only be disassembled, and one of the gears can be regarded as a fixed gear just like a motorcycle.But in fact, all three gears can be used, but if you change gears, you can't engage in gears like a car while running, but you have to stop the car to change gears.

Meaning, if I wanted to run within forty yards, I locked the gear in first gear.Get a control lever, because there is no clutch, I feel that the power is not strong, so I stop the car and shift to a higher gear.

This kind of modification is mainly because there is no clutch, and it can be installed, but it is best to use two hands to drive the side three wheels. It is too inconvenient to use one hand to control the direction and the other to shift gears.It's better to put the gear in whatever gear you want first. The foot brake has the same function as the clutch, so driving is simple.

People who have seen a three-wheeled battery car may understand that there is a gear directly in the place of the battery, and you can just press it, but the battery gear is easy to control, there is no transmission, it is just the strength of the power.This is the same principle as that one, that one is a button switch, and here it is replaced by a joystick.

Opening the gearbox, Luo Cheng took a look at the internal structure. It was the same as the later generations, it was just a simple combination of several sets of gears.Each gear is connected to the lever shaft, as long as the gear is connected to the lever shaft, it is enough, and the car transmission is equipped with a reverse gear.

Looking at the structure of the transmission, Luo Cheng felt that the third gear could be omitted, after all, it was mounted on the side three wheels, and the engine was just that of a motorcycle.Let's not talk about the motorcycle engine driving the load of the third gear.At the speed of the third gear alone, the direction of the three wheels here is handle-style. If the speed is too fast, it will definitely cause problems.It's better to directly ask for the first and second gears, and then the reverse gear can also be installed.

The side three-wheeler in the factory can be driven by itself after it is finished, and it is also good to have a reverse gear.

Just do it, fix the pole shaft directly, measure the distance, and then make a few poles to fix it.

Luo Cheng ordered Niu Zi and Dali to do it, they really couldn't understand, they just turned a few screws when they took it apart.And if this thing on the car is broken, they will replace it as a whole. No car repairman will repair the transmission.

After reinstalling the gearbox, Luo Cheng also instructed them to install it on the gear bearings of the side three wheels, and then connect it to the engine.Basically this is done.

The other is the installation of the brakes. To be honest, Luo Cheng really wants to get the brakes of the motorcycle, and install the brakes of the car, which can be installed by removing the wheels, but the body and stability of the car are so much stronger.Used on the side three wheels, if the speed is fast, it will really brake with one foot, and people will fly out immediately.

It is also the first time Luo Cheng has done to improve the braking performance.In the past, I tried my best to improve the car, but it always got worse and worse.But never intentionally changed it.

Fixing the brake device and taking out the brake pads can only reduce the friction area. Anyway, it is only a pair of brake pads, and it is not worth the money.

We are tossing around here, the official work time has passed long ago, all the workers in the workshop have come, and there are many people watching, because many people do not necessarily have a car to repair, and those who have a car repair are not in a hurry .

Seeing that there were a lot of people looking at it, and the repair shop also had welding machines, Luo Cheng simply asked a few more people to help. There were no requirements for many things, and there was no problem with big or small ones, as long as they were firm.

Let people use thick iron sheets to weld the left and right sides of the body, and then assemble the pedals.One for the gas pedal and one for the brake.In just one hour, with the help of six or seven people, it was assembled in a rough way.

Factory Manager Zhang also came to visit half an hour ago, waiting for the engine oil, lubricating oil and the like to be added, turned over, and the three wheels here were already a little weird.The side buckets were lengthened, partly sealed, and some pipes and lines were housed inside.

There are also wider pedals on the side of the locomotive, which is nothing. In fact, lengthening the side bucket and widening the pedals will make the side three wheels appear thicker.What is strange is that there are three more iron rods next to the widened side bucket, which is inexplicable to people.

The water tank was filled with water, the fuel tank was filled with oil, and Luo Cheng got on the tricycle.

It's hard to say whether it's a modification or an assembly, but it's just a mix-and-match of some motorcycle structures and car structures, Luo Cheng is also a little flustered.

The people who were still working in the workshop completely put down what they were doing, and wanted to see if the three wheels could start.

Stepping on the brakes, gently pushed the first iron rod on the right side forward, put his left foot on the starting pedal, and Luo Cheng stepped on it fiercely.One kick, and the engine started.

Starting the engine did not make the people in the workshop very excited, because it had already been started once before, and the key was to see if the car could start.

Luo Cheng didn't dare to step on the accelerator pedal, but his foot on the brake was slowly released, little by little, very subtle, and he was sweating a little from nervousness.Vince didn't move the car, but Luo Cheng was still slowly lifting his foot on the brake.

When the foot that stepped on the brake was raised to half the height of the pedal, the tires of the car started to move. Yes, it was not an illusion, it really started to move.Luo Cheng also continued to slowly lift his foot on the brake, and the three wheels started to drive completely, and quickly reached a speed of more than ten yards.

On the road in the factory compound, Luo Cheng slowly adapted to the driving and speed. He began to step on the accelerator slightly with his left foot, and the car quickly accelerated. There was no tachometer, and he pedaled by feeling.And no matter how many gears it is, this is no longer a three-wheeler, and the accelerator must never be pressed to the bottom.

It can drive normally, can accelerate, and finally brakes.While letting go of the accelerator, step on the brakes, but dare not step on the brakes too hard, for fear that the brakes will suddenly stop suddenly and people will not be able to control them.

When the car was about to drive back to the workshop, Luo Cheng controlled his strength in front of Director Zhang, and braked the car smoothly and steadily.

This is a complete modification of the three-wheeler, but there is a problem when traveling. The ordinary three-wheeler is much easier to get started, and people who don’t know anything will be able to drive it within ten minutes of learning.But the three wheels on this side are pedaled with your feet. If you don't step on the brakes at first, if you put it in a gear, the engine will shake and stop directly.And after braking to stop, you have to remember to shift the gear back.

Looking at the three wheels beside him, Luo Cheng found that his modification seemed to make the car's performance even worse, just like before the world changed.At least it is much more difficult to operate than Bian Sanlun.And the cost of auto parts is more expensive than that of motorcycles.

Factory Manager Zhang signaled Luo Cheng to get off the car. He wanted to try it out and asked Luo Cheng to sit in the sidecar to teach him how to operate it.

The car has been changed to this way, anyway, it doesn't matter if it is driven by itself, so it doesn't matter about operability.Luo Cheng nodded and sat in the side bucket.

First, let me tell you the function of these three iron rods. The two rods near the right hand side are the gears. There are only two gears, and the third one is the reverse gear.Then tell the factory manager how to operate it. In fact, it is the same as the automatic transmission cars of later generations, without clutch.

The factory manager who can drive naturally understood the principle immediately, and after shifting into first gear, he also began to release the brake slowly.Just like Luo Cheng just now, he moved quickly.For those who can drive a car, there is no difficulty.After walking around the factory twice, Director Zhang was also sad and happy.

What is worrying is that he also understands that the three rounds here do not belong to the three rounds anymore, so there is no need to think about picking up the repair list for the three rounds from the army.

But the good news is that this seems to be the cube car structure that Luo Cheng said, and most of the steering handles become steering wheels.Even if Luo Cheng said that he could make a 100% cube car, Director Zhang still didn't have a particularly stable bottom, and now he is not worried at all.

"Group leader Luo, group leader Luo, people from the street office called and said that two women were buying meat at the vegetable market in the morning, and they were reported as stealing the meat ticket and money. They said it was your sister, and now they want you to go there recognize people."
