Luo Cheng came to the auto repair shop, he came relatively early today, but after arriving at the factory, he found that Team Leader Jiang and they had already arrived at the factory, and they were disassembling the water tank of Director Zhang's jeep, and the team's car and team member Li Yiwen were not there.

Seeing that Luo Cheng was coming, Team Leader Jiang took the initiative to come forward to greet him and introduce the current situation. Li Yiwen went to the steel factory to get a hollow round pipe, and the thickness problem is not required at present, and the thickness of the pipe will be specially designed when it is really officially installed in the future.

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 installation, whether it can be started, and the other is whether it leaks oil or not. The pressure value can be adjusted by the valve, but if the seal does not leak oil, everything is in vain.

The welder master has been contacted, and he will come over when he officially goes to work at the latest. There is a fourth-level welder, and if the welding of a little round iron pipe cannot be sealed, then there will be a problem with how to assess the fourth-level worker.

Luo Cheng feels that he doesn't need to worry about anything, he is an engineer, at most he will discuss the idea of installation, and after the plan is set, there are no other steps to be checked by Luo Cheng.

And the matter of building a block car is not in a hurry now, and the chassis material size and model have been designed. Call the headquarters a little later, ask him to contact the superior department of the steel plant here, and then he doesn't have to go over in a bad way, and there is no need to pay, and the steel factory will send the materials that Luo Cheng wants.

As soon as the materials come, arrange two people to be responsible for cutting first. This thing can be operated by the people in the repair shop. As soon as the material is cut, the welders are called in the next day, and not only can the chassis be welded, but even the people in the repair shop can immediately install the bearings and wheels. The iron plate and steel pipe of the body are also sent by the steel factory, and once the construction starts, it will 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 again every day or two.

The manufacture of the cube car has not yet begun, and Luo Cheng plans to get the side three wheels up. There are also many workers in the workshop who arrive in advance, and there are more apprentices, or the apprentices themselves have to come before the masters. There can't be anything to do, the master is still waiting for them, they can only wait for the master.

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

"Niuzi, Dali, the two little masters came over to help, if Master Wang doesn't need you today, we will put the three wheels here together."

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 also got a few bundles of defective cloth back, and it is still in the warehouse. It's got them so much stuff that it's not a matter of words. And how can a seventh-level engineer not be capable.

"Team Leader Luo~."

"Well, take this gearbox apart for me."

The gearbox is a car gearbox, the new goods sent by Tiando, the brand new variable box to be disassembled, as an apprentice, at most I think that this new thing will not be broken when disassembled, but obeying the order is what the apprentice taught at the beginning of the master, I don't understand, you can see more and think more and ask more, but don't question others.

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

The car is three gears, the motorcycle is one gear, and the motorcycle simply relies on the throttle to let the engine bring more power to control the speed.

Just like a car, if you simply hang a gear, you can actually control the speed by the throttle, but that can only rely on the speed to drive the overall speed, not to mention the fuel consumption, and it is easy to damage.

But now there is only a car transmission, and it is impossible to install a gear on the side three wheels. Now I have to take it apart and use one of the gears as a fixed gear, just like a motorcycle. But in fact, you can use all three gears, but if you change gears, you can't be in gear like a car in operation, but you have to stop and change gears.

This means that if I want to run under 40 yards, I have to keep the gear in 1st gear. Get a control lever, because there is no clutch, I feel that the power is not strong, so I stop the car and hang up a higher gear.

This modification, the main thing is that there is no clutch, and it is okay to install it, but it is best to drive the side three wheels with two hands, one hand to control the direction and one hand to go to the gear again. It's better to put what gear you want first, and the foot brake plays the same role as the clutch, so that 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 press it, but that is the battery gear is easy to control, there is no transmission, but the strength of the electricity. It's the same principle as that, that's a pushbutton switch, and it's just a lever instead.

Opening the gearbox, Luo Cheng looked at the internal structure, which was the same as in later generations, just a simple combination of several sets of gears. Each gear is connected to the rod shaft, as long as the gear is connected to the rod shaft, it is fine, and the car transmission is with a reverse gear.

Looking at the structure of the transmission, Luo Cheng felt that the third gear could be abandoned, after all, it was installed on the side three wheels, and the engine was just the engine of the motorcycle. Let's not talk about the load of the motorcycle engine driving the third gear. The speed of the third gear is open, and the direction of the three wheels here is hand-handled, and it is definitely easy to have problems if the speed is too fast. It's better to directly ask for one or two gears, and then the reverse gear can also be installed.

The side three-wheeler in the factory will let itself drive after it is done, and it is not bad to have a reverse gear.

Just do it, just fix the rod shaft directly, measure the spacing, and fix a few poles when the time comes.

Luo Cheng instructed, Niu Zi and Dali did it, they really couldn't understand it, and they just twisted a few screws when they took it apart. And if this thing breaks down in the car, they will also replace it as a whole, and no car mechanic will repair the transmission.

After reassembling the gearbox, Luo Cheng also instructed them to install the gear bearings on the side three wheels, and then connect them to the engine. That's basically it.

The other is the installation of brakes, to be honest, Luo Chengzhen wants to get the brake device of the motorcycle, install the car brake device, and install it by removing the wheel, but the body and stability of the car are multiple and strong. Used on the side three wheels, if the speed is fast, it will really brake with one foot, and everyone will fly out immediately.

Changing the brake performance is also the first time Luo Cheng has done it. In the past, I tried to make the car better, but it kept getting worse and worse. But it has never been deliberately improved.

Getting the brake device right and taking out the brake pads can only reduce the friction area, anyway, it's just a pair of brake pads, and it's not worth much.

This side is tossing, the official time to go to work has long passed, all the employees in the workshop have come, and there are a lot of people watching, because many people do not necessarily have cars to repair, and those who have cars to repair are not in a hurry.

Seeing that there are many people, and the repair shop also has welding machines, Luo Chengcheng simply called a few more people to help, many things have no requirements from the original, there is no problem with the big and small points, as long as it is firm.

First, people weld the left and right sides of the body with thick iron sheets, and then assemble the pedals. One accelerator pedal, one pedal. In just an hour, with the help of six or seven people, it was put together in a crude way.

Director Zhang also came to visit half an hour ago, and when the engine oil, lubricating oil and the like were added, he turned over, and the three wheels here were already a little weird. The side bucket was lengthened, a part of it was sealed, and some pipes and lines were housed inside.

Driving the locomotive side also widened more pedals, which is nothing, in fact, lengthening the side bucket and widening the pedal 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 makes people look inexplicable.

The water tank was filled with water, the fuel tank was filled with oil, and Luo Cheng sat on the side three wheels.

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

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

Stepped on the brakes, gently pushed the first iron rod near the right hand side forward, put his left foot on the start pedal, and Luo Cheng stepped on it fiercely. With one kick, the engine went off.

Starting the engine didn't make the people in the workshop much excited, because it had been started once before, and the key was to see if the car could be driven.

Luo Cheng didn't dare to step on the accelerator pedal, but the foot that stepped on the brake was slowly loosened, little by little, very subtle, and nervous and a little sweaty. The car Vince didn't move, and Luo Cheng was still slowly lifting his foot on the brakes.

When the foot on the brake was raised to the height of the pedal, the tires of the car moved, yes, not an illusion, but really moved. Luo Cheng also continued to slowly raise his foot on the brakes, and the side three wheels also drove thoroughly, 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, his left foot began to step on the accelerator slightly, and the car quickly increased its speed. And no matter how many gears it has, this is no longer a side three-wheeler, and the throttle must not be stepped on to the end.

It can drive normally, it can accelerate, and finally it is time to brake. While releasing the accelerator, step on the brakes, and the brakes do not dare to step on violently, for fear that they will brake violently and people will not be able to control it.

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

This is a side three wheels completely modified successfully, but there is a problem with travel, the ordinary side three wheels, much easier to get started, people who don't know anything, learn about ten minutes will open. But the three wheels on this side are pedaled with their feet, and if they don't step on the brakes at the beginning and hang on the gear, the engine will shake off directly. And after braking and stopping, you have to remember to hang back the gear.

Looking at the side three wheels, Luo Cheng found that as if the world had not changed before, his modification seemed to make the performance of the car worse. At least it's much more difficult to operate than the side three wheels. And the cost of auto parts is also more expensive than that of motorcycles.

Director Zhang motioned for Luo Cheng to get out of the car, he wanted to try it, and let Luo Cheng sit in the side bucket so as to teach him how to operate.

The car has been changed to this, anyway, I drive it myself, so it doesn't matter how operable it is. Luo Cheng nodded and sat down in the side fight.

First of all, tell the role of these three irons, the two poles near the right-hand side are gears, just two gears, and the third is reverse. Then tell the factory director that the way of operation is actually the same as the automatic transmission car of later generations, there is no clutch.

The factory director who can drive naturally understands the principle at once, and after hanging up the first gear, he also begins to slowly release the brakes. Just like Luo Cheng just now, he quickly moved. For those who can drive a car, there is no difficulty at all. After two turns in the factory, Director Zhang was also sad and happy.

What worries him is that he also understands that the three wheels here no longer belong to the side three wheels, and he doesn't have to think about the side three wheels repair list if he wants to pick up the troops.

But the good thing is that this seems to be the square car structure that Luo Cheng said, and at most the steering handle becomes the steering wheel. Even if Luo Cheng said that he could make a square car 100% before, Director Zhang still didn't have a particularly stable bottom, and now he is not worried at all.

"Team Leader Luo, Team Leader Luo, someone from the street office called and said that there were two women who were buying meat in the vegetable market in the morning, and they were reported that the meat tickets and money were stolen, and they said that it was your sister, and now they want you to go over and recognize people."
