I believe everyone knows a lot about China automobile brands. Now many brands of cars are also pursuing to make their own auto parts, including the red flag L5. Almost all the parts are developed by Hongqi manufacturers themselves, but the gearbox still uses the 6AT gearbox of Aisin Japan, which is also a problem that China has never broken through, so everyone has a doubt. Why can't China build an AT gearbox of a car even if it can build a spaceship and an aircraft carrier? Where is the manufacturing difficulty of at gearbox?
AT gearbox has complex structure. As we all know, AT gearbox is an automatic gearbox. In fact, it is a hydro-mechanical automatic gearbox. You can see the complexity of the gearbox structure from the name. Compared with other gearboxes, the structure of AT gearbox is much more complicated, and the price of learning AT gearbox is naturally high, but its function is incomparable with other gearboxes.
Technical reference for patent protection. Every manufacturer knows the difficulty of AT gearbox development, so in order to keep their position and technology in the market, the developed brands have applied for layers of patents to protect their advanced technology, which makes it impossible for the later gearbox manufacturers to break through the technological progress.
A lot of data to be accumulated. No matter which brand of gearbox, the research and development process is very long, which requires a lot of practice accumulation and research and development data. At present, Aisin Japan's 6AT gearbox is also gradually developed based on the research data of the previous generation, but China does not have much technical experience and needs a long time of data accumulation, so it is still unable to break through this obstacle for the time being.
With the improvement of living standards, cars have become the main means of travel, and more and more people buy cars, which also provides more opportunities for many automobile manufacturers to continuously develop various new auto parts. The manufacture of AT gearbox needs more practice and research, and the difficulty should not be underestimated.
