ZF is highlighting two market successes for its tried-and-tested AxTrax AVE electric portal axle. Thirty-one London battery-electric double-decker buses built by Optare will be equipped with this technology and glide through the city powered solely by electricity.
The second success is marked by a new chapter in the partnership between ZF and New Flyer of America, Inc., the leading North American city bus manufacturer. The transport associations of several major U.S. cities have ordered 100 buses from the Xcelsior CHARGE model series equipped with ZF’s AxTrax AVE electric portal axle.
The AxTrax AVE electric drive axle drives low-floor buses up to a maximum axle load of 13,000 kilograms. The electric motors integrated into the wheel heads have a total output of 250 kW.
The AxTrax AVE was introduced for the first time in 2012 and has been successfully deployed around the world since. The electric drive axle can be combined with hybrid as well as fuel cell configurations or be powered by a battery. Due to the flat design, manufacturers have a great deal of freedom when it comes to designing the interior.
As a system supplier, ZF can also deliver the appropriate hardware and software to optimally align performance, efficiency and service life of the drive.
