SIGHTSEEING IN ELECTRIC UNVI DOUBLE-DECKER USING ZAWHEEL

In London the first electric sightseeing bus with the ZAwheel is now on the streets. The bus operator “The Original Tour”, a subsidiary of the international RATP Group, has taken into operation an open-top double-decker built by Unvi in Spain, the motor comes from Ziehl-Abegg in Kupferzell (Germany).

Unvi is the world's largest manufacturer of city tour buses with a reputation for custom-built vehicles. The Spaniards have chosen experienced component manufacturers as partners: BMZ for the batteries, Ziehl-Abegg Automotive for the powertrain and SAV Studio for the system integration.
The electric, open-top, double-decker bus which has started operating in London is 12 metres long and has twin axles. Inside the bus there is seating for 75 people. The vehicle is designed for a range of 150 kilometres so the key performance data is the same as on a conventionally-powered city tour bus – but with enormous advantages in terms of noise and emission levels.
Because an open-top, double-decker bus has no roof to position any batteries on, the battery packs are smaller than with any other motor concepts. In this case the advantage of the ZAwheel in order of energy consumption helps to minimize the batterypack.
In the current year, new open-top, double-decker buses for city tours have already been put into service in Paris and Amsterdam. The electric drive ZAwheel is available for the operators of hop-on/hop-off lines for new vehicles or for retrofitting. To underline this Ziehl-Abbeg had an open-top, double-decker bus from the year 1975 which will roll quietly through the streets of Berlin thanks to ZAwheel, on display at the IAA in September.
The ZAwheel is a wheel hub drive with the motor and control electronics mounted in the wheel hub. The ZAwheel does not need a gearbox.
