Chapter 211: QM200
A few days later, Ling Shizhe handed over the drawings of the transmission to Alison.
There are three transmissions, the first two are DCT and MET automatic transmissions, and the third is the MQ200MT manual transmission, which is the classic Volkswagen company in later generations.
When it comes to MQ200, many people may not know, but when it comes to Volkswagen's POLO, many people may know.
Anyone who has driven the polo knows that when driving the manual transmission of this polo, the short lever is very comfortable to hold, when changing gears, as long as you step on the clutch, with a few fingers lightly, the gear lever will be sucked into the gear you want, without dragging the mud and water, such a light operation, more so that the driver can enjoy the fun of the posture, even if it is in congestion and need to change gears frequently, it will not make you feel too tired.
The first generation of the Polo was born in 1975 and was available with two engines, 50 hp and 60 hp. At that time, it was a safe and practical family car, and the only fly in the ointment was that some unnecessary and impractical gadgets made the price of this car a little high, blocking it from entering the homes of ordinary people.
Later, after a lot of improvements, Polo began to become a lot more simple and practical, and began to be slowly accepted by people. In 1981 Volkswagen had the second generation of Polo.
The Polo was really accepted in 1984, when Volkswagen introduced a particularly affordable model on the second-generation Polo - the Polofox, a simplified version of the Polo tailored for single aristocrats and budget-conscious customers, and it was even cheaper, with only a 1.1-liter 45 hp engine to choose from.
The main reason for the popularity of this ultra-affordable Polofox is that Volkswagen's latest MQ200 manual transmission is installed on the Polofox.
Don't look at the MQ200 is a manual transmission, tell you that even around 2010, those domestic car companies, whether state-owned factories or private independent brands, still can't produce such transmissions.
In fact, the main reason is that the mystery of this transmission has not been understood, it adopts a very unique design, one is that he uses a multi-cone synchronizer, which is different from the single-cone synchronizer used in other ordinary models.
There is also his electronically controlled shift device, when changing gears in other transmissions, it is generally necessary to rely on the driver's arm to transmit force, and the swing gear lever touches the shift fork to change gears, which is a purely mechanical shift.
The transmission uses an electronically controlled shift device, when shifting gears, as long as you push to the gear, it will touch the switch of the motor, so that the fork controlled by the motor will be tightly engaged with the gear to complete the shift work.
In this way, this transmission is actually equivalent to a semi-automatic transmission, and when you fluctuate the gear lever, you are actually swinging a switch.
The biggest advantage of this transmission is that it is fuel-efficient, light to operate, at least 50% less shifting force than other transmissions, and its own energy consumption is not very high, and the noise control is excellent.
And his maximum torque of 200 N/m can be matched to many engines with this transmission.
The 21st century has passed for many years, and there are no private independent automobile companies in China, and those large state-owned factories have disdain to engage in these technologies, and they are busy making money.
And private car owners, even if they are enthusiasts, I'm afraid few people are willing to buy a new car, directly disassemble and study the transmission, even if it is disassembled, if there is no certain supporting knowledge, it can only be blind.
Therefore, there are really not many people in China who really know about this transmission.
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, Japan has done an excellent job in this area, although the Japanese studied under the Germans, but since the end of World War II, you have to admit that the Japanese have done even better than the Germans in this regard.
Especially in later generations, many cars with German logos were actually imported from Japan, such as the transmissions of many Volkswagen cars, which were actually purchased from the world-famous transmission manufacturer Aisin.
In fact, Aisin is just a subordinate unit of Toyota, specializing in transmission plants.
For a transmission, the machining precision of the gear is very important, such as this MQ200 transmission, there are many independent brands of automobile manufacturers in China to imitate 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, the transmission of the QQ car, which is known as the largest number of cars in the Celestial Empire, imitates the helical gear design in this transmission, but unfortunately due to the lack of precision in processing, the final result is that the tiger is 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.
But this problem is a problem for Ling Shizhe, Ambrera's new KTX-1100 intelligent CNC machine tool, to solve the problem of QM200 transmission machining accuracy is more than enough. Then the quenching, heat treatment and other problems after the gear processing should be paid attention to, you must know that Volkswagen was stuck in the problem for more than ten years before it was finally solved.
Ding Renhe and Yang Fawei, two Taiwanese compatriots, are professionals who have been engaged in transmission gear design and research for many years. Therefore, Ling Shizhe only said the beginning, and the two people behind him naturally understood.
QM200 didn't come out until 1984, so Ling Shizhe didn't have the slightest pressure to plagiarize.
The QM200 has only 5 gears, and Ling Shizhe made several modifications to it to become a seven-speed transmission. This improved version of the QM200 was renamed by him - PM160.
Along with PM160, PM260 and PM360 are also available.
PM260 copycat is Volkswagen's MQ250MT manual transmission, and it is also a classic manual transmission derived from Volkswagen, but this transmission is mainly used in some large-displacement cars, such as Magotan and Tiguan models a few years later.
The PM360 is also a copycat of Volkswagen's classic transmission MQ350, which is specially designed to match the higher power engine.
Like the QM200, the latter two gearboxes only have five gears, so Ling Shizhe also modified them, like the PM160, all to manual 7 gears.
QM250 and QM350 transmissions, Volkswagen has been launched for many years, so Ling Shizhe also made some adjustments when copying these two transmissions, so as to avoid the trouble of lawsuits in the future.
In this way, these three transmissions have become his Ling Shizhe's 'invention', and anyone who takes out a prototype and does a good job of powertrain can take these things and apply for a patent in a grand manner.
Well, the research of the Mercury series engine (4G63) cannot be stopped, there is currently only one 2.0-liter model, 2.4, 3.0, 3.5, 4.0, 4.5, 5.0, 5.4, 1.8, 1.6, 1.1, 0.8 liters and other series of engines with different displacements should also be studied. Regardless of the mainland or Taiwan/Bay, the engine, gearbox, chassis has always been their shortest, if the cooperation with the public fails, Ling Shizhe will take these technologies to cooperate with them, the old rules, and the development of consumer electronics technology, I sell parts to you, you sell your car, we make money together and cooperate happily.
