ZF expands steering system portfolio offering in China with addition of dual pinion systems

  • Dual pinion joins column and belt drive electric power steering (EPS) in the ZF portfolio; solidifies position as market leader for electric steering systems in China
  • Contributes to improved fuel economy and reduced greenhouse gas emissions
  • Electric power steering (EPS) embodies intelligent mechanical systems and enables enhanced safety and automated driving functions while contributing to comfort and maneuverability

Shanghai (China). ZF now has a significantly enhanced offering of electric power steering systems in China and globally with the introduction of its dual pinion system which is slated to launch in the Chinese market in 2018.

ZF expands steering system portfolio offering in China with addition of dual pinion systems

“As the second most prevalent type of electric steering system in the Chinese market, dual pinion is an important addition to the ZF product portfolio and is ideally suited for the mid-size vehicle and compact SUV segments both here and globally,” said Peter Lake, member of the ZF Board of Management, head of ZF Corporate Market and executive vice president of sales and business development for ZF TRW.

The dual pinion configuration utilizes the steering pinion and the drive pinion section of the rack independently from each other in contrast to belt drive EPS. The steering pinion section determines the desired responsiveness of the steering system while the drive pinion section is designed for high torque transmission and thus provides an efficient power assist by electric drive. Dual Pinion EPS is most suitable for vehicle applications with a maximum rack force between 9 and 12 kN.

“With the launch of the new dual pinion drive EPS, ZF is further enhancing its market-leading position for EPS in China – an important and growing technology area thanks to its clear cost and environmental benefits,” according to Thilo Bitzer, vice president, steering applications engineering at ZF TRW. “The technology can deliver a fuel saving of up to four percent with a corresponding reduction in carbon dioxide emissions when compared to a conventional hydraulically powered steering system.

Additionally, electric steering can be integrated with other systems to yield functions such as park assist and lane keeping assist/lane centering (when combined with ZF camera technology).

“EPS plays a key role for the growing semi- and fully automated vehicle control functions market in China and ZF is already introducing systems with redundant circuits and features to help ensure fault tolerant operation of the system,” Bitzer added.

ZF first started production of its EPS technology in 2001 and has since produced more than 30 million units for customers worldwide.
