ZF focuses on Chinese automakers - “Next Generation Mobility Days” in Shanghai
During driving demonstrations and technical discussions, customers were able to learn about the latest solutions for electromobility, automated driving, passive safety, and connected chassis technology for software-defined vehicles. Highlights at the Formula 1 racetrack in Shanghai included the first presentation of the purely electromechanical braking system "Dry Brake-by-Wire" as well as the China premieres of the electrically powered concept vehicle EVbeat and the magnet-free electric motor ISM.
“The future of mobility is rapidly shifting towards electrically powered, automated, and software-defined vehicles,” says Stephan von Schuckmann, member of the Board of Management at ZF. “In China, the largest and most dynamic automotive market in the world, we will continue to invest and grow together with our Chinese customers in China and worldwide — and with 'China-Speed.' Therefore, we see significant potential to increase our market share in China and the currently roughly 17 percent share of the Chinese market in our global sales.”
World Premiere: Fully Electromechanical Braking System
The new electromechanical braking system, also known as “dry” Brake-by-Wire, was presented to the public for the first time in Shanghai. This type of braking system no longer requires brake fluid; the braking pressure is not generated through the pressure of fluids in the hydraulic system, but rather through electric motors. The brake signals from the pedal to the electric motor are also transmitted purely electrically.
Compared to conventional braking systems, the new Brake-by-Wire system, just like the already introduced Integrated Brake Control (IBC), enables shorter braking distances, better recovery of braking energy, and lower maintenance costs. The innovative braking system was developed for software-defined vehicles by a consortium of ZF development centers in China, the USA, and Germany.
China Premiere: Concept Vehicle EVbeat and Magnet-Free E-Motor
Two more new developments in the field of e-mobility were presented in China for the first time in Shanghai: the concept vehicle EVbeat with the EVSys800 electric drive and the magnet-free E-motor I2SM.
The EVSys800 drive in the EVbeat concept vehicle is a modular 800-volt drive that consists of silicon carbide power electronics, the E-motor, and a reduction gearbox. Despite its extremely compact design and light weight, it doesn't skimp on performance in the EVbeat: the concept vehicle has a maximum torque of 5,200 Newton meters available at the rear axle.
In terms of dimensions, the drive saves 50 millimeters of installation space in width due to the compact reduction gearbox and ZF's patented 'Braided-Winding' technology of the E-motor, enabling a space-saving, coaxial installation on the drive axle. With a total weight of 74 kilograms, EVSys800, standardized to the same performance as the latest ZF 800-volt series drive, is also around 40 kilograms or one-third lighter.
Without Rare Earths and Magnets
With the I2SM electric drive, ZF has developed the world's most compact and torque-dense e-motor without magnets and rare earths. This will be a sustainable and powerful alternative to common electric drives. Unlike today's available magnet-free concepts of so-called externally excited e-motors, the energy for the magnetic field in ZF's I2SM (In-Rotor Inductive-Excited Synchronous Motor) is transmitted via an inductive exciter within the rotor shaft.
China's Positioning as a Strategic Market Continues to Strengthen
The technologies presented at the Next Generation Mobility Days were jointly developed by ZF's global and local teams, with many products developed by Chinese employees. Serving the Chinese market with the best products and technologies is ZF's long-term commitment in China.
In the past five years, ZF has increased its investment in research and development in the Asia-Pacific region from 220 million euros in 2019 to 380 million euros in 2022. The share of R&D in sales has risen from 2.8 percent to 4 percent.
What Does This Mean?
Since ZF's market entry in China in 1981, China's position as one of the company's strategic core markets has continuously strengthened. China is developing into an important hub for ZF for the global launch of products and technologies.
