en.Wedoany.com Reported - Schaeffler announced the official commencement of mass production for its star product, the new generation of distributed coaxial reducers, at its Taicang base. This product, leveraging its lightweight design, high efficiency, and excellent NVH (Noise, Vibration, and Harshness) performance, has successfully secured orders from leading domestic OEMs (Original Equipment Manufacturers), marking another significant milestone for Schaeffler in the field of distributed drive technology.
The newly produced distributed coaxial reducer is based on an NW-type two-stage coupled planetary gearset architecture and incorporates the industry's first stamped and welded planet carrier technology. Through precision stamping and laser welding processes, the reducer assembly's weight has been reduced by 15%, and its axial dimensions have been decreased by 5%. While achieving weight reduction and compact size, its torque density reaches up to 380Nm/kg, with a maximum transmission efficiency of 99%. These technological breakthroughs not only free up integration space for the electric drive system but also effectively reduce overall vehicle energy consumption, extending the range of new energy vehicles.
Regarding the product portfolio, Schaeffler's coaxial reducer series has achieved full torque coverage. In addition to the model currently in production, the company is set to launch a cast steel integrated coaxial reducer specifically designed for application scenarios requiring over 3600Nm, meeting the stringent demands of high-performance vehicle models for high torque output at the wheel end. Dr. Chen Xiangbin, President of Schaeffler China's E-Drive Business Unit, stated that distributed drive can provide a safer driving experience and enhanced driving pleasure, while coaxial technology is the core key to creating an efficient and compact dual-motor electric axle system.
Since the launch of its first coaxial reduction gearbox in 2018, Schaeffler's products have been widely adopted by renowned brands such as Audi, Porsche, Volvo, and Lynk & Co. To date, the global cumulative mass production of its coaxial reducers (including integrated e-axles) has exceeded 1.2 million units. As the electrification process accelerates in the Chinese market, Schaeffler plans to establish an annual production capacity of 1 million units in China within this year, continuing to lead the development of the technical roadmap for dual-motor torque vectoring distribution in the domestic market.
