Car wheel hub bearing patent research and analysis

Car wheel hub bearing patent analysis - 2020 02 - 07 auto-hub bearing ( 轮毂轴承) Now after hundreds of years of development, has accumulated rich precipitation technology and the development of many branches. A, wheel hub bearing, the development process of wheel hub bearing at present has developed to the fourth generation. But over the years the rapid development of automobile industry to promote the progress of automobile wheel hub bearing units, also put forward higher requirements on automobile wheel hub bearing performance. Reduce the structure weight of automobile wheel hub bearing, reduce the negative friction of bearing, reduce the bearing structure of the volume, improve the sealing performance and design techniques, wheel hub bearing the intelligent technology and ABS technology development direction of the future. Wheel hub bearing, therefore, the patent application will revolve around the high performance of the bearing ring, narrow bearing structure, the wave rolling technology, to reduce the friction resistance, ABS technology constantly updated development. Second, wheel hub bearing patent situation based on the wheel hub bearing Chinese patent applications in the field of literature has carried on the statistics, from the perspective of patent application has made a research on the development of wheel hub bearing unit. This paper mainly through the database (in Chinese CNABS、CNTXT) As well as foreign language database ( SIPOABS、VEN、DWPI) In the comprehensive search and statistics ( Specific retrieval time for December 29, 2017) , from the perspective of each country and category of the applicant for a patent, analyzed its development status accordingly. ( A) Domestic wheel hub bearing application ( 1) Domestic application trends. Since 2002, the domestic has since the application case of wheel hub bearing, wheel hub bearing in the number of domestic made considerable development. ( 2) The country's main applicants. In domestic at present is mainly concentrated in a few wheel hub bearing company specializing in the production of auto parts, domestic wheel hub bearing application has a tendency to concentrate in a particular applicant. This side also reflects the wheel hub bearing application is established on the basis of the research and manufacturing, with actual production support, wheel hub bearing application has a strong production application value. ( 3) Domestic applicants. At present, the domestic wheel hub bearing mainly concentrated in the enterprise applications, in addition, there are part of the scientific research institutions and individuals engaged in the research and development of wheel hub bearing, the bearing manufacturing enterprise can strengthen communication and scientific research institutions and the folk scientists, to promote the technical update of wheel hub bearing in a greater power. ( 4) Domestic applicant country respectively. At present domestic applications, wheel hub bearing accounted for the vast majority of Chinese applicants, foreign applicants are mainly Sweden, Japan, Germany, South Korea, the Netherlands, the United States and other automobile research and development production power. These countries in China an application for a patent for the wheel hub bearing will bring some to China's domestic related research and development manufacturing enterprise competitive pressure. ( 2) The global application situation of wheel hub bearing, 1) The global application trends. Car wheel hub - in 1998 Constantly increasing 2017 patent of the global application. With the continuous development of automotive technology, wheel hub bearing technology is also continuously updated, the addition of some new technology and new technology to wheel hub bearing in steadily towards the next generation. Therefore, predictably, the number of wheel hub bearing will continue to prosper. ( 2) The main application state. In the global top 10 wheel hub bearing applicant, wheel hub bearing application basic focused on automotive power established and emerging automobile manufacturing powers such as China and South Korea. Three, the major conclusion of foreign big companies such as NSK bearing production company and SKF company maintained an absolute advantage in the field of wheel hub bearing, and the accumulation of technology also keep the leading level in the whole world, it has the most patent technology, patent technology content is the highest, leading the global development direction of automobile wheel hub bearing unit. In recent years we have made gratifying progress in the wheel hub bearing, at home, such as some companies such as wanxiang group made great achievements in the field of production research and development hub bearing, its also made a big progress in patent technology, currently in the domestic leading level. But we should also note that the current domestic wheel hub bearing patent technology is still in the second level in the world, currently on the international advanced research and development of bearing production enterprises have a big gap. In order to promote China's globally and voice in the influence of wheel hub bearing, our country should strengthen the study of the field, and constantly learning and introducing foreign mature, the key technologies in his long, fill yourself short, constantly improve the technological level of our country. In addition, to enhance the sensitivity of the relevant market, grasp the development direction of wheel hub bearing unit. At the same time, the domestic each big enterprise also should with colleges and outstanding individual applicants for further communication and cooperation, combination, go forward hand in hand. Finally, the research and development production enterprise also should be paid attention in the filed of intellectual property rights and developed better technology should be promptly to apply for patents at home and abroad, using the mature of the patent system to plan out a comprehensive patent layout, with intellectual property rights of legal weapons to escort for the enterprise development.
