TRW Automotive Holdings Corp. (NYSE: TRW) will supply its Belt Drive Electric Power Steering (EPS) system to Chinese automaker Great Wall Motor Company for its next gen mid-sized Sport Utility Vehicle (SUV) to be launched in 2015. SUV’s are a fast growing vehicle segment in China with 43% % sales increase in 2013 as compared to 2012 as per IHS data. TRW is also supplying its Electrically Powered Hydraulic Steering (EPHS) technology to Ferrari’s ‘LaFerrari’ – the 1st Ferrari to feature hybrid propulsion.
TRW will operate from its regional production base to be a cost effective source for its fuel-saving and emission reducing EPS technologies. In the last 2 years, TRW has installed equipment to produce and assemble belt drive units at its Anting facility. Line capacity is in the range of 800,000 units annually.
TRW offers 2 Electrically Powered Steering (EPS) solutions that require power only when steering assist is needed. There’s a column drive unit which is mounted on the steering column and a belt drive wherein assist power is applied directly to the rack with a belt drive and ball nut mechanism. In comparison to traditional hydraulic power steering, both offer fuel economy and CO2 emissions benefits. Fuel saving of 0.3 to 0.4 L/100km with carbon dioxide emission reduction of about 7-8g/km can be attained.
“We have already launched our column drive technology with both China domestic and international customers and are now introducing our latest innovation – EPS belt drive – in China,” said Lake. “We are pleased to be supporting China’s largest SUV manufacturer, Great Wall, as they launch new vehicles into the market.”
