ARTICULATED BUS SHOWCASES ‘E-MOBILITY’
A NEW PROTOTYPE articulated bus “impressively demonstrates” system solutions to simplify the transition to electric-powered city buses, according to commercial vehicle driveline and chassis technology specialist ZF.
The 18-metre ‘artic’ bus is equipped with two of the “proven” AVE 130 electric portal axles, with a total of four motors providing powerful thrust.
As the company explains, stricter emissions limits and the public debate on fine dust pollution are putting pressure on public transport operators to reduce emissions, meaning bus manufacturers are investing resources into system integration and even more on development.
In order to make the transition to local zero-emission city buses and low-emission logistic transport trucks as easy and flexible as possible, ZF is providing commercial vehicle manufacturers with technology and systems expertise, it states.
The company offers its AVE 130 electric portal axle and the new CeTrax electric central drive for city buses, acting as a one-stop shop for all the components required, says ZF. This means manufacturers can choose conventional low-floor and high-floor platforms, as well as low-entry buses for electrically powered models, which makes the electrification of vehicle fleets more economical and convenient, it adds.
In long-haul transport logistics and coach application, electric drives are no longer limited to being a fanciful idea; in fact, the hybrid version of the ZF TraXon commercial vehicle transmission exhausts previously unused power savings potential at maximum output, the company says.
AVE 130, CETRAX AND TRAXON
• AVE 130 includes advanced inverters, drive control and power electronics all fully integrated, guaranteeing optimal energy efficiency – and a larger range;
• CeTrax is built on a plug-and-drive approach, so can be integrated into existing vehicle platforms without major changes to the chassis, axles, statics or differential;
• TraXon Hybrid, with electric motor between combustion engine and transmission, allows hybrid functions in heavy commercial vehicles.
