Over 400 sets of Jingjin electric drive system supporting the Winter Olympics new energy fleet

On February 4, 2022, the world-renowned XXIV Olympic Winter Games (XXIV Olympic Winter Games), that is, the 2022 Beijing Winter Olympics, was grandly opened. It is a solemn promise made by China to the world. The pure electric and hydrogen-fueled buses that fully embody the spirit of “hosting the Olympics in a green way” are the main force of transportation for the Winter Olympics. Jingjin Electric’s EMAT two-speed variable-speed electric drive assembly and SD365 motor are matched with more than 400 pure electric and hydrogen energy buses of Beiqi Foton Ouhui, providing high-quality power and excellent reliability.

The Winter Olympics spans the three regions of Beijing and Hebei. Vehicles have to travel long distances in severe cold, over mountains and mountains, and require extremely high grades and power; the event attracts worldwide attention, and the system must be absolutely reliable; the power system with low noise and high comfort is also required. Bring a relaxed and pleasant ride experience to passengers from all over the world. Jingjin Electric and Foton Ouhui worked closely together to bring two classic and reliable products, two-speed transmission system and SD365 drive motor, to the Winter Olympics.

According to the bus network, Jingjin Electric is the first company in the world to start to develop and promote the two-speed transmission for electric drive. Jingjin Electric EMAT electromagnetic shift two-speed transmission is a two-speed automatic transmission specially developed for new energy commercial vehicles. It has been sold as a package as early as 2017. It is especially suitable for long-distance intercity, group travel, high-slope passenger cars and special-purpose vehicles. car application. EMAT electromagnetic two-gear shift does not require the traditional AMT complex and fragile shift operating mechanism, and at the same time removes the fork, gear sleeve, synchronizer and other mechanisms. Compared with the traditional four-speed system, the two-speed EMAT reduces the number of shifts by two-thirds, improves comfort, achieves light weight, simplifies structure, and reduces failures.

In fact, this Winter Olympics event is a perfect “graduation answer sheet” for Jingjin Electric’s first-generation EMAT two-speed box. In 2022, Jingjin Electric will launch the second-generation EMAT transmission, which adopts Jingjin Electric’s second-generation electromagnetic shift clutch (faster shifting speed) and a new-generation drive motor. The system torque output is as high as 6500 Nm, which is higher than the first-generation. Output was up 73 percent; transmission weight was reduced by 18 percent, and an optional power take-off was added. It will successfully replace the traditional four-speed or six-speed transmission, fully realize “multi-purpose in one box”, and be flexibly applied to pure electric, hybrid and extended-range 10-12 meters passenger cars and logistics vehicles and sanitation vehicles of no more than 18 tons. Provide a more powerful, more reliable, more comfortable, lighter, more efficient and more economical power system for new energy commercial vehicles.
