Renben Shares Participates in the 2021 Global xEV Electric Drive System Technology and Industry Conference

From June 17 to 18, the 2021 Global xEV Electric Drive System Technology and Industry Conference was held in Shanghai. This forum focused on pure electric and hybrid electric drive systems, focused on energy saving, high voltage, high speed, OTA and other technical directions, and tracked key materials and power devices. At the same time, the TOP50 selection of China's leading electric drive industry chain in 2021 in the NE era came to an end. The company was invited to attend the forum and delivered a keynote address entitled ' Trends and Futures of New Energy Vehicle Bearings '.

New energy vehicles have become a hot topic in global automobiles, and the country is also vigorously supporting the development of new energy vehicles. According to the national development strategy, China plans to form an independent and complete industrial chain by 2035. The technical level of self-owned brand pure electric and plug-in hybrid vehicles is in line with the international level. New energy vehicles account for more than 50% of total vehicle sales, of which pure electric vehicles account for more than 95% of new energy vehicles. In the field of pure electric vehicles, the promotion and application of pure electric technology in household vehicles, official vehicles, taxis, rental service vehicles and short-distance commercial vehicles will be realized.

The forum also received strong support from automobile OEMs and parts companies, including: FAW New Energy Vehicles, General Motors, FAW-Volkswagen, Geely Automobile, BAIC New Energy, Xiaopeng Motors, Nidec, Valley Austrian, United Electronics, Shanghai Electric Drive, Honeycomb Electric Drive, Founder Motor, Huayu Electric Drive, CRRC Times Electric, etc. Experts and scholars from relevant mainframe and spare parts companies, scientific research units and other fields respectively delivered keynote speeches at the forum to seek the healthy and rapid development of the industry.

With the development of new energy vehicles, people put forward higher requirements for motor bearings of new energy vehicles in order to pursue the comfortable driving of new energy vehicles, stable high-speed operation and rapid acceleration and deceleration in the driving process. Through independent research and solving key common problems in the design, manufacturing, testing and evaluation of high-end bearings, the design criteria of high-speed bearings suitable for service conditions, the composite heat treatment technology of mechanical and secondary quenching, and the manufacturing process specification of bearings are established. The stable batch controllable manufacturing technology, test evaluation and verification technology are broken through, and the whole chain technology system of high-speed bearings covering design, manufacturing, test evaluation and application verification is formed. The successfully developed series of high-speed, low-energy-consumption and long-life deep groove ball bearings have good high-speed, rapid acceleration and deceleration, long life, low friction torque, low noise, low temperature rise and other performances. The performance indicators are equivalent to foreign high-end products. It has been widely recognized by the world-renowned automobile main engine supporting enterprises for supporting global mid-to-high-end vehicles.
