Era: Retired from the army at the beginning and returned home - Chapter 73 Assembly and Modification

“There is a plan, but I don’t know if it will work. We have to try it to know the specific situation. We don’t have the parameters and drawings of the motorcycle now, but we can even make it run with four wheels. Is it possible to make it run with three wheels? If it can stump us, let’s modify it like a small car.”

“Renovation, can this~~ be done?”

Director Zhang has never been able to figure out the three wheels here. In fact, his thinking has always been focused on assembly. And if you need spare parts, you still need to go to the motorcycle machinery factory to apply. But for a car repairman to apply for motorcycle parts, you can imagine how unlikely it is. There are thousands of accessories for motorcycles. Do you want to apply for thousands of them? In that case, it is better to ask the motorcycle factory to apply for one motorcycle.

Now the motorcycle factory has just started official production this year, with a maximum output of several hundred units a year. If the military region and local departments are divided, even if there are motorcycles in Ngee Ann City, they will not be allocated car repair shops.

“What’s wrong? The car engine is too big, but there is a small one ready-made. The fuel tank is also easy to solve. You can make one by yourself. Just have someone build one that is about the same size as the three-wheelers over there. Even if it doesn’t match it, it will be fine.” It’s not difficult to reinforce and fix it. The transmission structure and electricity are also not difficult. If you have a pen and paper, I will draw a structural diagram for you.”

If Luo Cheng was asked to build an engine, he would have no choice but to stop cooking. But with an engine and a power system, he really knows how to do it. Of course, he also needs some car accessories. Modification is not manufacturing after all.

First of all, there is an engine and an ignition device, which is usually a device that links the car key. Cars and motorcycles have different models at most, but the principle is the same. This thing is available in the factory. The clutch pedal is also a matter of size, but the principle is different from that of a car. A motorcycle has a clutch cable.

That is, the motorcycle needs to be started with the key first, and then the generator is started through the clutch cable. Tractors are driven by rockers, motorcycles are driven by pedaling, and cars are driven by clutches and transmission.

In this era, Jiefang cars were still dual-clutch, with different gears and different clutch pedals. On the shuttle bus driven by Zhao Dajin, Luo Cheng saw that the dual-clutch model needed an extra transmission device.

But no matter what, as long as you understand the principles and have the drawings, it is for those who like to modify. Even if there is something wrong with the car, even if the model is different, the repair will not be confusing.

There is a pedal device on the side three wheels. You can see if it can be used. There is also a chain case car, but it needs a chain. For this, you can directly go to the local machinery factory to customize one according to the requirements.

Anyway, some details can be gradually improved later, such as headlights and gear shifting. Those are all minor issues. At least the problem of getting the car to spin must be solved first.

Director Zhang looked at the bulk structure diagram drawn by Luo Cheng and felt a little big-headed. Although he was a sixth-level repairman, if a car was given to him to repair, he would be able to figure out what the problem was by looking at the ignition or the sound. .

But when asked to analyze the various connections between a car’s power system, he really didn’t have the skills. I don’t understand a bit, but I think what Luo Cheng said makes sense.

According to Luo Cheng, the original frame of the smooth-edged tricycle could not be accommodated in the assembly he designed. The side bucket needs to be cut and lengthened to hold some configuration parts. If it is not lengthened, people who sit on the sides will lose the space on their square legs.

“This is the strength of engineers. With a three-wheel frame, a power unit can be designed to make it run.”

Director Zhang didn’t understand, but he didn’t dare to question the strength of the seventh-level engineer. Luo Cheng even gave him a feeling that, let alone a three-wheeled frame, Luo Cheng might be able to make it drive if he gave Luo Cheng a few tires. stand up. The kind that doesn’t require a frame car cover.

“Well, Luo Gong, what are you going to do as the first step?”

“The ignition device of the car should be in the warehouse. Let’s roughly design a fuel tank first, and the transmission structure is not urgent. I have to clean the toilet tomorrow anyway, so I can ask someone to help get the three-wheeled wheel over there to the pool outside the toilet. Tires Can I get a replacement?”

“There’s nothing wrong with the tires. Let’s go to the tire factory and bring some over. But Luo Gong, if you do this, what are the chances of making the three wheels move here?”

Director Zhang was thinking in his heart at this moment, if the three wheels here could be repaired, then everything would be easy to say. But if you can’t repair it, you can use old ones for some small things, such as water tanks and fuel tanks. Even if you get one yourself, it doesn’t cost much.

But wires, ignition equipment, electrical equipment, etc., although there are backups in the factory warehouse. But these things are all public property. When they are used up, they need to be inspected, and everything must have a receipt. If there is only one left in the warehouse, it will definitely not be used by Luo Cheng, because once it is gone, it will be reported to the logistics department for repurchase. If you used the adjustment before, you need to clean it up and check it.

So if you are not sure, you really can’t use it.

“Hmm~.”

o(*￣▽￣*)o, thought for a while. In fact, a battery car has been modified before, and it was also obtained by Principal Dai, and it was changed into a powerful gasoline-burning car. It can be said to be a success, or it can be said to be a failure.

Success means that the car is powerful and can drive very fast. The failure was that the car had not been driven a few times, and all the wiring on the car had been burned out. The wiring was too thin and could not be driven.

But now we use automobile wires to connect motorcycle engines. This engine only has ten horsepower, so it is impossible to burn the wires.

If you simply let him run, it will be 100% successful according to the principle. Just like changing human-powered tricycles into electric ones in later generations, it is really not difficult. But the most important thing is speed change, shock absorption and pressure change. Without these, the car will rush forward with maximum horsepower as soon as it starts. There is also a reversing device. Some motorcycles do not have reversing capabilities. Cars that do have reversing are larger and many are equipped with a power-operated reversing device.

Being able to drive is only the foundation, performance and functionality are the pursuit.

“According to theory, there should be 100% no problem.”

“Theory, what about practice?”

“It’s 100% fine to just start it.”

“real?”

“Well, there’s no problem.”

“Okay, let’s do it.”

Director Zhang thought for a while and seriously decided that this was just a modified tricycle. If it fails, you will definitely be held responsible if the accessories used on it are scrapped. But if it succeeds, it’s not just a matter of using it for Luo Cheng. It’s just for Luo Cheng. He won’t take the risk.

There are probably only a few three-wheelers in the entire Ngee Ann District. There used to be a lot of them, but where have they gone? Troops, it is almost impossible to see side three wheels on city streets. But there are still many troops, and many more are damaged beyond repair.

If the factory can trim three wheels, then the repair shop can cooperate with the army. The level of attention that repair shops receive will be greatly increased, and even due to the expansion of repair business, the number of establishment quotas in the factory will also increase. Many people who have been apprentices in the factory for a few years can become formal weavers.
