The world-famous "North Korea-US talks" have just concluded, and Trump, who has been "innovated," has backfired and pushed us to a halt. The "trade friction" has been rekindled, and the technology that has been used to raise tariffs on high-end manufacturing industries for hundreds of billions of imported goods has never been easier. The embargo on exports and the uproarious ZTE Incident that plagued the country some time ago made it more and more clear to the Chinese people how important it is to have independent intellectual property rights and core technologies. In view of the status quo of the development of the automotive industry, the automotive three-part engine and suspension system are usually the focus of consumers. Usually, their advantages and disadvantages can also be displayed through relatively intuitive data, while relatively little attention is paid to users. The transformers can only be experienced through the test drive, but as a very important drive system for the entire vehicle's power performance, the road to domestic brands is equally difficult.
Mass market is subject to people who will be the mainstream of the future?
As a result of the mismatch between engine torque and speed, the transmission does not occupy much space in the vehicle, but its technical content is not low. The current mainstream transmission types on the market can be divided into manual transmissions (MT) and Automatic transmissions, which can be roughly subdivided into automatic transmissions (AT), electronically controlled mechanical transmissions (AMT, continuously variable transmissions (CVT), and dual clutch transmissions (DCT), in terms of construction, design principles, and performance characteristics. Differences, each transmission has its own different occasions.
In the early days of the automotive market, manual transmissions MT dominated the domestic transmission market with its low cost and low fuel consumption. However, with the improvement of technology level and reduction of transmission costs and consumer market demand, automatic transmissions are occupying more. The more market share came, the penetration rate of automatic transmissions in the US and Japan even reached 94% and 84%.
Global market sales and share of automatic transmissions and manual transmissions
As far as the domestic market is concerned, according to data released by the CLUCC in 2017, the penetration penetration rate of passenger cars for domestic manufacturing has risen from around 20% in 2005 to more than 60%, combined with sales in the Chinese auto market in 2017. The future of the automatic transmission is "temptation" that no one can refuse.
Domestic sales and share of manual and automatic vehicles for passenger cars
As the differences in the technical routes of the transmissions described above have determined the different scenarios they apply, the existence of such application scenarios is also a solution to some of their actual problems. For example, in North America, fuel prices are not Sensitive, stable and comfortable AT transmission, and suitable for large displacement features will be more market; and like Japan's narrow roads, resources are mainly dependent on imports, the more fuel-efficient CVT will be more popular, so Japan's small-displacement models In the European market, as the technology continues to mature, DCT transmissions that are better in terms of fuel economy, comfort, and user control experience are showing strong growth momentum.
Market share of domestic manual transmission declining
Demand for domestic automatic transmission increases year by year
It can be seen that the same is an automatic transmission. Each manufacturer's research and development for the transmission is aimed at different application scenarios. We are directly “taking it in.†Although it is convenient and efficient to meet the laws of economic development, the first round is completed. The market's occupation will seek to dig deeper into the market potential. The lack of independent intellectual property rights and the lack of core technical support will manifest itself. The more urgency of such a large brand of independent brands becomes apparent. With high purchase costs and limited supply, the production capacity has been so restrained and the grandfather is required to ask his grandmother to smile. This is a natural time. It is imperative to master the independent research and development of core technologies.
Self-owned brands are catching up but gaps and market gaps are still
Sitting on a huge passenger car market, China's OEMs and parts manufacturers will naturally not miss opportunities. In the international market, the source of transmissions for various OEMs is mainly composed of three aspects: First, the production of professional transmissions. Enterprise purchases (such as ZF in Germany), secondly, purchases from OEMs that have production of transmissions (such as Toyota's subsidiary Aisin), and they are self-developed, self-produced, and self-produced; very coincidence is the domestic market. The situation is reflected.
The 8AT transmission developed by Shengrui Drive of Weifang, Shandong Province, has been equipped with the relevant models of many domestic OEMs, and won the National Science and Technology Progress Award in 2016, breaking the monopoly in the transmission manufacturing field in Germany, Japan and other countries, which is of great significance; In addition, Geely will establish a joint venture company to build 6AT transmissions for Aisin, which will provide a solution to the lack of production capacity for OEMs that do not have an independent transmission brand. Finally, in the area of ​​independent research and development, Great Wall’s 7DCT will pass the assessment of “Top Ten Transmissions in the Worldâ€. In its high-end brand WEY series models. It can be said that all parties have shown great determination in solving the transmission problem that restricts the development of the host plant. Although the methods are different, the objectives are similar. What is rarely known is that Chery, which has been unique in its own brand with its technical strength, was the first host company to develop the first domestic automatic transmission. However, even if there are a lot of OEMs who invest heavily, it is because of technical bottlenecks. And many issues such as market acceptance are not resolved in a day. The transmission of Sunray Drive has not yet received orders from the first-tier manufacturers. The cooperation between Geely and Aisin means giving up control of the core technologies of the transmission and the 7DCT of Great Wall. Has been mass production and user testing, in addition to Chery Wanli Yang CVT25 off the assembly line, once again refreshed the industry's impression of its "engineering male" technology flow, according to its plans this transmission will be the first to launch in the third quarter of this year, listed New car Arrizo GX, as Chery's sales, this positioning of 8-10 million A+ class car market performance can look forward to.
Transmission configuration details in recent years
Although some achievements have been made in the development of domestic transmissions at present, there is still a significant gap from international standards. Purchasing from mature suppliers will still be the main way for domestic OEMs to solve transmission problems in the near future. On the other hand, the structural complexity of the transmissions of different technical routes is different. It is often not involved in a main engine plant, but also in the supply chain of upstream and downstream supply chain suppliers. Therefore, it is necessary to further advance the entire automotive industry. The upstream and downstream environments are also in urgent need of improvement. Whether it is China's ZF or Aisin, as well as first-class accessory suppliers like BorgWarner, Schaeffler, and Continental, it will take a long time and a lot of energy to nurture.
On the whole, the installed capacity of automatic transmissions of domestic joint venture brands can reach over 70%, while the independent brands are only about 17%, and most of them are purchased from foreign transmission manufacturers. The “Zhongxing Incident†once again gave the people a very sad one. Lessons, "The core technology can not be relied on," and in the field of CVT, DCT and AT gearboxes, local companies have now achieved a complete breakthrough and gradually get rid of people's plight, and in the context of the industry where the auto industry is constantly opening up its share ratio, At this point in time, it is crucial to complete the shortcomings of the independent brands in the transmission field.
