reborn industrial empire

A good transmission will bring endless driving pleasure to drivers, and this is also a point of pride for German cars.

Whether it is high-end cars such as BMW and Mercedes-Benz, or Volkswagen targeting ordinary customers, they all emphasize the joy of driving.

On the one hand, this is due to the Germans' many years of car-making experience, especially the tuning of the chassis. Another very important aspect is the transmission that their cars match.

The reason why the transmissions of German cars are excellent depends entirely on the machining accuracy of their transmission gears.

Of course, Japan is also doing extremely well in this regard. Although the Japanese learned from the Germans, in recent decades, you have to admit that the Japanese have done even better than the Germans in this regard.

Especially nowadays, many cars with German car logos actually have transmissions imported from Japan, such as Volkswagen. As far as Jin Xiaoqiang knows, the transmissions of many Volkswagen cars are actually imported from the world-famous gearbox manufacturer Aisin. Procured.

In fact, Aisin is just a subsidiary of Toyota, a branch factory specializing in transmissions.

For a gearbox, the machining precision of the gears is very important, such as this mq200 transmission. There are also many independent brand automobile manufacturers in China imitating this transmission.

It is not an exaggeration to say that this transmission can be called the originator of transmission research for Hyundai China’s independent brand car companies.

For example, a few years later, the transmission of the QQ, which was said to be the most popular model in China, imitated the helical gear design in this transmission. Unfortunately, due to insufficient processing precision, the final result was that a tiger cannot be like a dog.

Because the processing precision is not enough, when the car is running and changing gears, the gears do not bite tightly enough, resulting in the noise of the transmission being even greater than the noise of the car.

Moreover, there will be a series of problems such as difficulty in shifting gears, waste of fuel, short gearbox life, etc.

So after Jin Xiaoqiang took out the drawing of this transmission, he repeatedly reminded the two masters Ding Weizhong and Yang Dingwei that they must pay attention to this finishing issue.

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

Ding Weizhong and Yang Dingwei are both professionals who have been engaged in transmission gear design and research for many years. Their experience in actual production is certainly much richer than that of Jin Xiaoqiang.

So when Jin Xiaoqiang emphasized this issue to them, the two of course readily agreed.

Last year, Jin Guozhu spent several hundred million to introduce a second-hand production line from Aisin in order to expand production capacity and further upgrade the company.

Since its introduction, this production line has been debugged several times and under the exploration of Ding Weizhong and Yang Dingwei, it has just come online and is capable of production.

Jin Guozhu is quite visionary. He has long had the idea of ​​making his gear factory bigger and stronger. At this time, he is no longer satisfied with producing gear accessories for transmissions. He already has the idea of ​​producing complete transmissions.

However, the development issues of Xinghe Village later attracted attention, so they did not invest too much energy in this area. However, Ding Weizhong and Yang Dingwei were different.

After introducing the second-hand production line into the factory, they have been studying those machine tools. Although they are not the current internationally mainstream five-axis linkage machine tools, they are just somewhat outdated four-axis linkage machine tools.

The machined parts still need to be polished using other instruments, but the processing accuracy of these machine tools is still much more precise than the equipment they originally used.

Moreover, this transmission has been on the market for some years, so it is not a secret, and the materials required for this manual transmission are also available in their factory.

So it’s not too troublesome to produce.

But the only bad news is that they can't get the special alloy steel for the gears of the transmissions used by Volkswagen.

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

The difference is that the service life of the mq200 transmission they produce may be worse than that of Volkswagen.

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

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

Furthermore, even if a car has been driven for 20 years, it will probably be scrapped. As far as the entire vehicle is concerned, the problem may not only be with the transmission, but also with other parts.

.

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

Although Jin Xiaoqiang also wants to solve this problem, after all, the material used in this gear is an innate problem, and it is really difficult for them to overcome it at present.

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

But for now, using the only materials available to make this transmission is not without its benefits.

You must know whether this transmission is good or not, but the cost is thousands of dollars higher than other ordinary manual transmissions. You must know that the cost of several thousand dollars is still very influential to ordinary consumers.

.

But if slightly inferior materials are used now, the cost will not be as high as the cost of Volkswagen's transmission, which is quite beneficial to controlling the cost of the entire vehicle.

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

And Jin Xiaoqiang here is not idle either. He continues to plagiarize other manual transmissions from Volkswagen, such as 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

On a car with a displacement of 2.0l.

For example, Bora, Golf, Polo and other models all use this transmission.

Compared with the current engine "researched" by Jin Xiaoqiang, it is sufficient. However, if his engines undergo technical upgrades in the future, this transmission will not be sufficient.

The mq250 that Jin Xiaoqiang wants to 'research' this time is also derived from a classic manual transmission from Volkswagen, but this transmission is mainly used in some large-displacement cars, such as the Magotan, Tiguan, etc. a few years later.

Car model.

However, these models have not yet been born, so now is a good time for Jin Xiaoqiang to copy them.

In fact, Volkswagen also has a transmission mq350 that matches a higher-power engine, but this transmission has not been introduced into the country, and the two manual transmissions are currently sufficient for Jin Xiaoqiang, so he is not 'researching' that mq350

transmission.

Moreover, these two transmissions are now sufficient for Jin Xiaoqiang's future plans, because these two transmissions will need to be upgraded in the future.

For example, currently, mainstream manual transmissions only have five gears, and six gears will become popular in the next few years, so there will be enough room for upgrades in the future.

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

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

The same goes for these transmissions now. While he was 'researching', he also made fine adjustments, so as to avoid the trouble of lawsuits in the future.

And such an engine and transmission would openly become Jin Xiaoqiang’s ‘invention’. After he took out the prototype and completed the powertrain, he could take these things and apply for a patent openly.

It doesn’t matter whether it’s a copycat or not. After all, in this era, these things created by Jin Xiaoqiang are not considered copycats. Instead, they can be regarded as a breakthrough in the field of engine powertrain.

Ding Weizhong and Yang Dingwei are studying the process for producing the mq200 transmission, while Jin Xiaoqiang here is 'researching' the next mq250 transmission in full swing.

Liu Xiaoliang, on the other side, is continuing his work of data testing. This work is boring to others, but to him, it is definitely something he enjoys.

The data required for the database is huge. Although Liu Xiaoliang has accumulated some data at present, compared with the huge data they need, such a small amount of data is just a small wave in the ocean.

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

While Jin Xiaoqiang was studying the problem of designing the mq250 transmission, he was also thinking about the mainstream direction of transmissions in the future automotive world.

Although manual transmission is the first choice for many driving enthusiasts, for more consumers in the future, cars are just a means of transportation, and in the future, they will always face stop-and-go traffic jams in cities.

Therefore, for this group of consumers, automatic transmission models will be their first choice.

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

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