Chapter 121: Not a Successful Side Three Round

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 Director Zhang's jeep water tank. The team's car and team member Li Yiwen were not there.

Seeing Luo Cheng arriving, Team Leader Jiang took the initiative to say hello and introduce the current situation. Li Yiwen went to the steel factory to get the hollow round pipe. The thickness issue is not required at the moment. The thickness of the pipe will be specially designed when it is actually officially installed in the future.

Luo Cheng looked at the hand-assembled booster pump. The casing was not painted. However, this was a minor problem. The main issues were two points: whether it could be started after it was installed, and whether it leaked oil. The pressure value can be adjusted through the valve, but if the seal cannot leak oil, everything is in vain.

The welder master has been contacted and he will be here when he officially starts work at the latest. Here is a fourth-level welder. If the round iron pipe cannot be sealed after welding a little, then there will be a problem with how this fourth-level worker passed the assessment.

Luo Cheng felt that he didn't need to worry about anything when installing the booster pump. He was an engineer. He could at most discuss the installation ideas. After deciding on the plan, there were no other steps that Luo Cheng had to check.

There is no rush to make the cube car now. The chassis material, size and model have already been designed. He called the headquarters a little later and asked him to contact the superior department of the steel factory here. Then he went there in a decent manner and did not need to pay. The steel factory would send the materials Luo Cheng wanted.

Once the materials arrive, arrange for two people to be responsible for cutting them first. The people at the repair shop can do this. As soon as the material is cut, the welders are called in the next day. Not only can the chassis be welded, but the repair shop people can even install the bearings and wheels immediately. The iron plates and steel pipes for the car body were also sent from the steel factory. Once the work started this time, it would not be easy to listen to it, because the whole process requires the cooperation of welders, and it is not easy for people to come back one day and then another one or two days.

The production of the cube car has not yet started, and Luo Cheng plans to build a three-wheeled car. There are also many workers in the workshop who arrive early, and there are more apprentices. In other words, the apprentices themselves arrive before the masters. They can't have their master wait for them if something happens, they can only wait for their master.

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

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

Niu Zi and Dali came over with smiles upon hearing Luo Cheng's greeting. Putting aside Luo Cheng's skills, the food has improved a lot since Luo Cheng came to the factory. He also brought back several bundles of defective cloth, which are still in the warehouse. This provided them with so much supplies, and it was not just a matter of words to call them help. And how could a seventh-level engineer be incompetent?

"Team Leader Luo~."

"Well, take this gearbox apart for me."

The gearbox is a car gearbox. It is a new product sent from Amado. The brand-new variable box needs to be disassembled. As an apprentice, at most I wonder if this new thing will be broken when it is disassembled. However, obeying orders is the apprenticeship of the master at the beginning. If you don’t understand what is taught, you can read more and think 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 combined with the engine's throttle power to form stronger torque.

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

Just like a car, if you simply shift into first gear, you can actually control the speed by relying on the accelerator, but you can only rely on the rotational speed to drive the overall speed, which consumes a lot of fuel and is easily damaged.

But now we only have automobile transmissions, and it is impossible to install a gear shifter on the third wheel. Now we can only disassemble it and use one of the gears as a fixed gear like a motorcycle. But in fact, all three gears can be used, but when changing gears, you cannot shift gears while running like a car. Instead, you have to stop the car to change gears.

Meaning, if I want to run within forty yards, I lock the gear in first gear. Get a control lever. Since there is no clutch and you feel the power is not strong, stop the car and shift into a higher gear.

The main reason for this kind of modification is that there is no clutch, and it can be installed. However, it is best to drive a three-wheeler with two hands. It is too inconvenient to control the direction with one hand and put the gear in the other hand. It's better to put it in whatever gear you want. The foot brake and clutch have the same function, so driving is simple.

People who have seen a three-wheel battery car may understand that there is a gear directly on the battery, and you can press it. But that is the battery gear that is easy to control. There is no transmission, just the strength of the electricity. This principle is the same as that one. That one is a button switch, but here it is replaced by a control stick.

Opening the gearbox, Luo Cheng took a look at the internal structure. It was the same as in later generations, just a few simple gear combinations. Each gear is connected to a rod shaft. You only need to connect the gear to the rod shaft, and that's it. Moreover, the car transmission has a reverse gear.

Looking at the structure of the transmission, Luo Cheng felt that the third gear was unnecessary. After all, it was mounted on a tricycle, and the engine was just a motorcycle engine. Let’s not talk about the load of the motorcycle engine driving the third gear. When driving at this speed in third gear, the direction of the three-wheeler here is handlebar type. It is definitely easy to cause problems if the speed is too fast. It's better to just ask for first and second gears, and then put the reverse gear on.

The three-wheeled car in the factory can be driven by itself after it is finished, and it would be nice to have a reverse gear.

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

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. Moreover, if this thing on the car breaks down, they will replace it as a whole. No car repairman will repair the transmission.

After reinstalling the gearbox, Luo Cheng also directed them to install it on the gear bearing of the third wheel, and then connect it to the engine. Basically this is complete.

The other thing is the installation of the brakes. To be honest, Luo Cheng really wants to install the brake device of the motorcycle and install the brake device of the car. It can be installed by removing the wheel. However, the car body and stability are very complex. Use it on a side tricycle. If you drive fast, it will really brake and people will fly out immediately.

It was also Luo Cheng's first time to improve brake performance. I used to try hard to improve the car, but it always got worse and worse. But I have never deliberately corrected it.

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

Things are going on here, and the official time for work has long passed. All the workers in the workshop have come, and there are many people watching, because many people do not necessarily have cars to repair, and those who have cars are not in a hurry to repair them. .

There were many people watching, and the repair shop also had welding machines, so Luo Cheng simply called a few more people to help. Many things had no requirements. It was no problem if they were larger or smaller, as long as they were firm.

First, let people use thick iron sheets to weld them on the left and right sides of the body, and then assemble the pedals. A gas pedal and a brake pedal. In just one hour, with the help of six or seven people, it was put together crudely.

Director Zhang also came to visit half an hour ago. After adding the engine oil and lubricants, he turned over and found that the three-wheeler here was already a little weird. The sidecar was lengthened, partially sealed, and some pipes and wiring housed inside.

It doesn’t matter if the side of the motorcycle is widened and the pedals are wider. In fact, lengthening the sidecar and widening the pedals will make the sidecar appear thicker. What is strange is that there are three more iron poles next to the widened side bucket, which is confusing.

After adding water to the water tank and oil to the fuel tank, Luo Cheng got on the tricycle.

It's hard to tell whether this is modification or assembly. It's just a mix of some motorcycle structures and car structures. Luo Cheng was 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-wheeler here could run.

He stepped on the brakes, gently pushed the first iron rod on the right side forward, put his left foot on the starting pedal, and stepped on it hard. One kick and the engine roared.

Starting the engine didn't make the people in the workshop very excited, because it had already been started once before. The key was to see if the car could drive.

Luo Cheng didn't dare to step on the accelerator pedal. Instead, he slowly loosened his foot on the brake, little by little, very slightly, and he was so nervous that he started to sweat a little. Vince's car didn't move, and Luo Cheng was still slowly lifting his foot to apply the brake.

When the foot on the brake was raised to half the height of the pedal, the car's tires 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-wheeler started running completely, and soon reached a speed of more than ten yards.

On the road in the factory compound, Luo Cheng slowly adapted to driving and speed. He began to lightly step on the accelerator with his left foot, and the car quickly accelerated. There was no tachometer, so he stepped on the pedal by feeling. No matter what gear it is, this is no longer a three-wheeler, and the accelerator must not be depressed to the bottom.

It can drive normally, accelerate, and finally brake. While letting go of the accelerator, I stepped on the brakes. I didn't dare to step on the brakes hard, for fear that the brakes would suddenly stop and I would lose control.

When the car was about to return to the workshop, Luo Cheng controlled his strength in front of Director Zhang and stopped the car smoothly and smoothly.

This is a tricycle that has been completely modified successfully, but there is a problem when traveling. Ordinary tricycles are much easier to use. People who don’t know anything can learn to drive in about ten minutes. But the three wheels here are stepped on by foot. If you don't step on the brake at the beginning, if you hang it in gear, the engine will shake and stall. And after braking to stop, you have to remember to shift back into gear.

Looking at the tricycle, Luo Cheng found that it seemed to be the same as before the world had changed. His modifications seemed to have made the car's performance even worse. At least it is much more difficult to operate than the side three wheel. And the cost of auto parts is also more expensive than that of motorcycles.

Director Zhang signaled Luo Cheng to get out of the car. He wanted to give it a try and asked Luo Cheng to sit in the sidecar so he could teach him how to operate.

The car has been changed like this. Anyway, you drive it by yourself, so the operability doesn't matter. Luo Cheng nodded and sat in the side bucket.

First, tell me the functions of these three iron rods. The two rods near the right hand side are gears, just two gears, and the third one is reverse gear. Then I told the factory manager how to operate it. It was actually the same as the automatic transmission cars of later generations, it just didn't have a clutch.

The factory manager, who knew how to drive, naturally understood the principle immediately. After shifting into first gear, he began to slowly release the brakes. Just like Luo Cheng just now, he quickly started to move. For those who know how to drive a car, it is not difficult at all. After walking around the factory twice, Director Zhang felt both sad and happy.

Worryingly, he also understood that the Sanlun here no longer belonged to the Sanlun, and there was no need to think about the repair order for the Sanlun from the army.

But the good news is that this seems to be the square car structure that Luo Cheng said, with most of the steering handles turning into steering wheels. No matter how much Luo Cheng said before that he could make a 100% cube car, Director Zhang still didn't have a particularly stable foundation. Now he is not worried at all.

"Team Leader Luo, Team Leader Luo, someone from the subdistrict office called and said that two women were buying meat at the vegetable market in the morning. They were reported that the meat tickets and money were stolen. They said they were your sisters and they want you to come over now. Recognize people.”
