TRW has announced it is to supply its belt drive electric power steering (EPS) system to Great Wall Motor Company for a mid-sized SUV, set to be launched in 2015.
Sport Utility Vehicles are the fasting growing vehicle segment in the rapidly expanding Chinese market with a 43% sales increase from 2013 compared to 2012 according to IHS data.
“TRW’s Belt Drive system is an ideal choice for mid to large size SUVs as larger vehicles require greater steering rack forces, said Peter Lake, executive vice president, Sales and Business Development. “As Chinese consumers continue to desire the greater flexibility and utility of SUVs, TRW has the local capacity to satisfy demand for these vehicles.”
TRW offers two EPS systems to OEMs. One column drive unit, which is mounted on the steering column and a belt drive system, as selected by Great Wall. The belt drive device takes its assist power is applied directly to the rack with a belt drive and ball nut mechanism. Significant fuel economy and CO2 emissions benefits can be realized with both systems when compared with traditional hydraulic power steering. The technology can deliver a fuel saving of 0.3 to 0.4 L/100km, with a corresponding reduction in carbon dioxide emissions of approximately 7-8g/km.
“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.”
