If domestic cars want to be strong, they must have a strong backing.
Volkswagen and BMW are by no means strong, and the Continental Group and ZF behind them have made an indispensable contribution, solving a large number of spare parts problems for the main engine factory, and collaborative production has also brought them a faster development speed.
BMW does not have to worry about the gearbox problem, the public does not have to worry about the turbine problem, these are the benefits brought by the industry.
China did not have a strong and excellent backing before, the history is pushed forward 7 years, we even have some companies in the use of Mitsubishi engines, to the Hyundai Group to purchase transmissions, technical disadvantages let us always bow our heads and purchase goods with others.
No way, the backwardness of the industry is so cruel.
But in recent years, China's industry has developed very fast, the new track has spawned a large number of strong enterprises, BYD has cultivated Fordy, becoming the most competitive enterprise in the electric vehicle industry, the market valuation is very high, behind the industrial product precipitation, technology accumulation of strength.
There are also strong players on traditional tracks, such as Aoyama.
Aoyama service is still the traditional market, the core business is the gearbox business, the past 5 years Aoyama transmission in the market has a good market share, the main promoter is Changan.
In the two major plates of manual transmission and automatic transmission of Qingshan Transmission, the manual transmission has been very mature, although it does not have the silky feeling of the Volkswagen manual transmission, but it also has the characteristics of low cost and high reliability.
In terms of automatic transmission, the Aoyama DF727 has been verified on models such as Changan UNI-T and Jietu X90, with good reliability, low fuel consumption and clear logic, and the market performance is good at present.
Of course, the DF727 also has some gaps with the DSG's gearbox.
However, Aoyama continues to optimize in this technology, and has created a DF733 gearbox in this technology, which is a gearbox with better technical parameters, and it is currently the first time to carry the model is most likely to be UNI-V.
Technically, it has increased the maximum torque limit to 300 Nm, the best partner for small displacement transmissions, and 300 Nm of torque has been able to adapt to displacement engines below 1.5T, and reliability has been enhanced.
At the same time, the speed ratio is expanded, and a larger speed ratio will inevitably lead to better fuel economy, in addition to the further reduction of volume and mass, and the lightweight design is taken into account.
In terms of transmission efficiency, it has increased to 95.9%.
From the technical parameters, the DF733 gearbox is more mainstream than the volkswagen's current mainstream DQ200 gearbox in terms of maximum withstand torque, transmission efficiency and gear ratio range.
At present, Volkswagen's products within 150,000 are mainly DQ200 dry double clutch, and it is already a very stable existence in the dry double clutch camp.
The DF733 is a more costly wet dual-clutch transmission, which is better in terms of reliability, of course, Volkswagen's advantage is so many years of tuning experience, after all, the EA211 engine matching logic is very clear, and the advantages of this power architecture are very obvious.
But the iteration of technology can not be limited to this set of standards, better standards have emerged, Blue Whale 1.5T with FD733 this power system, whether it is horsepower, torque, reliability, transmission efficiency is not weak.
The same price you can buy this set of power system in fact, enjoy the technology upgrade, China PK foreign investment after the biggest benefit, landing on the product point of view, in the past you 150,000 to buy a Volkswagen Langyi TSI + DSG power architecture, but today you can use 120,000 to buy 1.5T + DF733 power architecture.
Maybe the Chinese brand is slightly weaker in logical matching, but the comprehensive overall analysis, our Chinese products are actually stronger, after all, the current dual-clutch transmission is not a very difficult technical route, and our Chinese brand is more likely to give a longer cycle of warranty cycle.
Therefore, I have reason to believe that supporting Chinese brands will always benefit us Chinese consumers.
