Automatic transmission solenoid valve basically monopoly by foreign capital

Automatic transmission solenoid valve basically monopoly by foreign tianya blog what time automatic transmission is the core of automatic-shift cars spare parts. Solenoid valve and hydraulic valve is the core of automotive automatic transmission parts, engineering machinery, agricultural machinery and machine tool industry such as the key basic parts, demand is big. Month, associate professor, school of mechanical and vehicle engineering of hunan university Dr Dian-lun xue said in an interview 'domestic independent brand solenoid valve and the hydraulic valve body need break through the design, manufacture technology, realize the industrialization of mass, low cost. Otherwise, the domestic independent brand automatic transmission chain is difficult to form. 'Developed countries hydraulic valve and solenoid valve enterprise monopoly market, the current domestic automobile automatic transmission hydraulic valve and solenoid valve market is America's warner and Eaton, Germany Bosch and Japanese multinationals such as east side monopoly. These multinational companies set up wholly owned enterprises or joint ventures in China are from developed countries purchase the original hydraulic valve and solenoid valve. China's independent development of hydraulic valve and solenoid valve with jiangsu Jin Run car power transmission technology company, xi 'an aerospace research institute and the guizhou jettisoned automotive electronic technology co. , LTD. These enterprises in the process of marketing a crackdown by the enterprises in developed countries. 'With the development of automobile automatic transmission to block, solenoid valve was designed to be smaller and smaller. In this way, can reduce weight, and to provide more space, also can reduce the manufacturing cost of solenoid valve. At the same time, most of the body control valve is designed to be smaller, material from steel to aluminum, more sensitive to control valve, can effective movement under higher frequency signal, provides faster response speed and higher oil control stability. 'Beijing university of aeronautics and astronautics traffic, vice President of the institute of science and engineering professor xiangyang, introduces the development trend of the electromagnetic valve. Domestic automobile market demand diversity, the automatic transmission hydraulic valve and solenoid valve inevitably brought industrialization of automobile automatic transmission parts such as the characteristics of many kinds. Hydraulic valve and solenoid valve in the developed countries enterprise existing production mode and process equipment is not suitable for China's actual situation. Dian-lun xue to predict, therefore, the domestic market of hydraulic valve and solenoid valve must consists of three most is a direct import product, used for IDA, plus turco (tianjin love and trust Guangzhou) Bonzi, Shanghai, nanjing by Mr Fu and other developed countries enterprises in China wholly owned brands and joint venture brand automobile automatic transmission; Two is a wholly foreign owned enterprises and sino-foreign joint venture products for Shanghai gm, dongan mitsubishi and sino-foreign joint venture brands such as chery automobile company and the domestic part of the independent brand; Three is the domestic independent brand products, used in shandong ShengRui, dongying tyne and other domestic independent brand automobile automatic transmission. Independent brands lack of user support for a long time, many domestic automobile enterprise implement to supplier does not pay attention to cultivate independent brands, leading to domestic enterprises independent development of hydraulic valve and solenoid valve lack of automobile automatic transmission industry chain downstream user support, also is the lack of market. In this way, the domestic independent brand hydraulic valve and solenoid valve no engineering opportunities, also is impossible to realize industrialization. 'Although the domestic hydraulic valve and solenoid valve manufacturing capability, however, the independent brand automobile automatic transmission industrialization is still in the market period, lead to low production of hydraulic valve and solenoid valve, high cost, poor quality, difficult to meet the needs of mass production. This is almost no independent brand automobile automatic transmission hydraulic valve and electromagnetic valve is the root cause of the professional manufacturers. 'China gear professional association secretary general and secretary general of the China automotive automatic transmission innovation alliance Li Sheng regret it. At present, China has become the world's largest car sales of the world. Authorities predicted results show that the years, the domestic need ten thousand units of riding vehicles with independent brand of automatic transmission, automatic transmission each need at least a solenoid valve. As a result, almost no domestic independent brand the status quo of automatic transmission hydraulic valve and solenoid valve enterprises urgently need to change. Key in and user for joint development of years, jiangsu Jin Run automobile transmission technology companies invest a lot of manpower and financial resources, has overcome the hydraulic control valve plate structure design and optimization, electro-hydraulic control module design and development platform, valve plate die casting mold design, die-casting, real-time porous heterosexual complex thin-walled parts of precision machining and body assembly test technical challenges, such as the development of stepless automatic transmission hydraulic valve, hydraulic automatic transmission hydraulic valve body is well received by users.
