In recent years, the development speed of automotive transmissions has shown a leaps and bounds, and the application of advanced manufacturing technology in automotive transmissions is even more splendid. The so-called advanced manufacturing technology refers to a collection of technologies, equipment and systems for manufacturing products, including mechanical engineering technology, electronic technology, automation technology, information technology, etc., mainly including computer-aided design, computer-aided manufacturing, Integrated manufacturing systems, etc.
The automotive transmission is used as a shifting device for coordinating the rotational speed of the automobile engine and the actual traveling speed of the wheel. It can shift the engine to its optimum power performance. The development trend of the transmission is more and more complicated, and the degree of automation is getting higher and higher. Of course, the automatic transmission will be the mainstream in the future.
In Europe, the automatic transmission ratio of passenger cars is over 97%, and the United States and Japan are 80% and 60% respectively. Compared with developed countries in the world, only a few cities in China use it, and the assembly rate is less than 10%. With the change of urban traffic conditions, in order to adapt to the frequent start and stop of buses and reduce the labor intensity of drivers, the proportion of automatic transmissions will become higher and higher. In the domestic bus market, experts predict that the assembly ratio of China's automatic transmission will reach 50% after 10 years.
According to the “2014-2018 China Automotive Transmission Industry Production and Sales Demand and Investment Forecast Analysis Report” released by the Foresight Industry Research Institute, as early as 2011, the annual production and sales volume of Chinese automobiles has exceeded 18 million units. A throne. However, at that time, the number of cars owned by thousands of Chinese people was still less than 100. From the perspective of the whole world, the number of cars for thousands of people was 120. Compared with the developed countries, the number of cars for thousands of people is still very low. It is expected that the future will be 5- In the past 10 years, automobile consumption demand will maintain a steady and rapid development momentum of 5%-10%. It is estimated that the sales volume of automobiles will reach 25 million in 2015. In the case of rapid growth in the automotive industry, China's automotive transmission industry is facing significant opportunities. In 2011, China's auto transmission market reached nearly RMB 87 billion, and it is growing at a rate of more than 15% per year. It is expected to reach RMB 170 billion in 2015.
Green cars, energy saving and emission reduction have become the main theme of the development of the automobile industry today. The combination of the application of new energy vehicles and the "intelligent" of vehicles in the future is also the direction of the development of the automobile industry. In developed countries, the development status and demand of vehicle transmissions have their own characteristics. Manual and automatic coexistence, and the demand ratios of different regions are different. Domestic transmissions are mainly manual, and the automatic transmission occupancy rate is rapidly increasing.
The development of automotive transmissions and the application of advanced manufacturing technologies are complementary. The development of transmissions can drive the application of advanced manufacturing technologies, and the application of advanced manufacturing technologies can promote the development of transmissions.
