A good transmission will bring endless driving pleasure to the driver, and this is also a buying point that German cars are proud of.

Whether it is BMW and Mercedes-Benz in high-end cars, or Volkswagen in the face of ordinary customers, they are emphasizing the pleasure of driving.

On the one hand, this is due to the many years of experience of the Germans in building cars, especially the tuning of the chassis, and another very important aspect, which is the transmission that their cars match.

The excellence of the transmissions of German cars depends entirely on the precision with which the gears of their transmissions are machined.

Of course, in this regard, he has done an excellent job, although he studied under the Germans, but in recent decades, you have to admit that he has done even better than the Germans in this regard.

Especially in many cars with the German logo, in fact, the transmission is imported from the book, such as Volkswagen, as far as Jin Xiaoqiang knows, the transmission of many Volkswagen cars is actually purchased from the world-famous gearbox manufacturer Aisin.

In fact, Aisin is just a subordinate unit of Toyota, specializing in transmission plants.

For a gearbox, the machining precision of the gear is very important, such as this MQ200 transmission, and there are many independent brand car manufacturers in China imitating this transmission.

It is not even too much to say that this transmission can be called the originator of the transmission research of Hyundai Celestial Empire's own brand car companies.

For example, a few years later, the transmission of QQ, which claimed to be the largest model in the Celestial Empire, imitated the helical gear design in this transmission, but unfortunately due to the lack of precision in processing, the final result was that the tiger was not an anti-dog.

Because the precision of the processing is not enough, the gears are not tightly engaged when the car is running and shifting, and the noise of the transmission is even greater than the noise of the car.

Moreover, there will be a series of problems such as difficult to hang the file, fuel consumption, short life of the gearbox and so on.

Therefore, after Jin Xiaoqiang took out the drawings of this transmission, he repeatedly thought that Ding Weizhong and Yang Dingwei emphasized that we must pay attention to this finishing problem.

And be sure to pay attention to the quenching, heat treatment and other issues after the gear is produced.

Ding Weizhong and Yang Dingwei are professionals who have been engaged in gearbox gear design and research for many years, and their experience in actual production is of course much richer than Jin Xiaoqiang.

So when Jin Xiaoqiang emphasized this aspect with them, of course the two readily agreed.

Last year, in order to expand production capacity and further upgrade the enterprise, Jin Guozhu spent hundreds of millions of yuan to introduce a second-hand production line from Aisin.

This production line, introduced so far, has been debugged several times and under the exploration of Ding Weizhong and Yang Dingwei, it has just been launched and can be produced.

Jin Guozhu is still quite discerning, and has long had the idea of making his family's gear factory bigger and stronger, at this time he is no longer satisfied with the production of transmission gear parts, he already has the idea of producing a complete transmission.

It's just that he was attracted by the development of Xinghe Village later, so he didn't put too much effort into this area, but Ding Weizhong and Yang Dingwei are different.

After the introduction of the second-hand production line in the factory, they have been studying those machine tools, although they are not the current international mainstream five-axis linkage machine tools, but some outdated four-axis linkage machine tools.

The machined parts still need to be polished and re-used with other instruments to complete, but the machining accuracy of these machine tools is still much more precise than the equipment they originally used.

And it's no secret that this transmission has been on the market for a few years, and the materials needed for this manual transmission are also available in their factory.

So it's not too much trouble to produce.

It's just that the only bad news is that the special alloy steel for the gears of the transmissions used by Volkswagen is not available.

Although they also use special alloy steel to make their own gears, the material of the special alloy steel they use may still be worse than that of Volkswagen.

The difference is that the MQ200 transmission they produce may have a worse service life than the Volkswagen's.

However, if you have to make a specific distinction, that is to say, if Volkswagen's transmission is used in the car and can be used for 30 years, then theirs can also be used for 20 years.

But the average person, the one who will drive the same car for 20 years?

In addition, even if a car has been driven for 20 years, it is estimated that it will be scrapped, and when the time is concerned, as far as the whole vehicle is concerned, I am afraid that the problem is not only the transmission, but also the other places.

Of course, if you meet a car owner who doesn't care about the car, or for some reason, often needs to use extreme ways to drive, then the durability of this transmission may be much worse than that of Volkswagen.

Although Jin Xiaoqiang also wants to solve such a problem, after all, the materials used in this gear are congenital problems, and it is really difficult for them to overcome them at present.

If you really want to overcome this problem, you can only wait until after July, until Jin Xiaoqiang goes to Hong Kong and finds that person.

However, for the time being, it is not without its benefits to use the only materials available at present to make this transmission.

You must know that this transmission is good, but the cost is also thousands of dollars higher than other ordinary manual transmissions, and you must know that the cost of thousands of dollars is still very influential for ordinary consumers.

Now, if a slightly worse material is used, the cost will not be as high as the cost of Volkswagen's transmission, which is quite good for controlling the cost of the whole vehicle.

Ding Weizhong and Yang Dingwei took these drawings and happily studied how to produce them.

And Jin Xiaoqiang here is not idle, he is still continuing to plagiarize other manual transmissions of Volkswagen, such as the MQ250.

You must know that the maximum torque transmission value that this MQ200 can withstand is only 200 Nm, so this transmission is only suitable for assembly on cars with small displacement engines, such as 1.6L, or 1.8L, or ordinary 2.0L such displacement cars.

For example, Bora, Golf, Polo and other models are using this transmission.

Compared with the current engine that Jin Xiaoqiang 'researched', it is enough, but if his engines are upgraded in the future, this transmission will not be enough.

And this time Jin Xiaoqiang wants to 'study' the MQ250, which is also derived from a classic manual transmission of Volkswagen, but this transmission is mainly used in some large-displacement cars, such as Magotan and Tiguan models a few years later.

However, none of these models have yet been born, so now is a good time for Jin Xiaoqiang to plagiarize.

In fact, Volkswagen also has a transmission mq350 that matches a higher power engine, but this transmission has not been introduced into China, and at present, these two manual transmissions are enough for Jin Xiaoqiang, so he is not 'researching' the transmission of the MQ350.

And now these two transmissions are enough for Jin Xiaoqiang's future plans, because these two transmissions will be upgraded later.

For example, at present, the mainstream manual transmission only has five gears, and in the next few years, it will become popular to have six gears, so there is plenty of room for upgrades in the future.

Of course, while Jin Xiaoqiang is studying these two transmissions, he will also make a series of adjustments, which is not complete plagiarism, because this will cause unnecessary patent infringement lawsuits.

Just like when he was 'researching' those engines, he would make some fine-tuning of those engines based on the mature experience of the next few years.

And now he is working on these transmissions in the same way, he has also made fine-tuning while 'researching', so as to avoid the trouble of getting into lawsuits in the future.

And such an engine and transmission will become his Jin Xiaoqiang's 'invention', so that after he comes up with a prototype and does a good job of powertrain, he can take these things and apply for a patent in a grand manner.

It doesn't matter if it's a copycat or not, after all, in this era, these things made by Jin Xiaoqiang are not copycats, but can be regarded as a breakthrough in the field of engine powertrain.

Ding Weizhong and Yang Dingwei are studying the process flow for the production of the MQ200 transmission, while Jin Xiaoqiang here is in full swing 'researching' the next MQ250 transmission.

On the other hand, Liu Xiaoliang is continuing his data testing work, which is boring for others, but for him, it is definitely a happy thing.

The data required by the database is huge, and although Liu Xiaoliang has accumulated some data here, compared with the huge data they need, such a little bit of data is just a small wave in the sea.

In this way, in the hands of enthusiast-level car enthusiasts, a future legend quietly set sail......

While studying the design of the MQ250 transmission, Jin Xiaoqiang is also thinking about the mainstream direction of transmissions in the future automotive world.

Although manual transmission is the first choice of many driving enthusiasts, for more consumers in the future, the car is just a means of transportation, and in the future in the city will always face a stop-and-go traffic jam, so for this part of the consumer, the automatic transmission model will be their first choice.

Now their technical level and the materials they have are enough to produce manual transmissions, but if they want to produce automatic transmissions, it is still a big problem!

And for Jin Xiaoqiang, design is not a problem, but the material is the most critical, and now he is really looking forward to July!
