ELECTRIC DRIVE SOLUTIONSFOR COMMERCIAL VEHICLES

E-MOBILITY IN PUBLIC TRANSPORTATION

More and more city buses drive electrically. They need a drive solution that is flexible in use. Flexibility in driveline technology for electric city buses is essential while "e-bus" does not exist: There are hybrid buses where a diesel engine acts as an aggregate supplying electric power and there are fuel cell buses where the fuel cell produces electricity through the chemical reaction of hydrogen and oxygen. In contrast, overhead line and induction buses receive their energy for the drive from the municipal power supply system, while other e-buses carry batteries for energy storage on board.

The AVE 130 can be used as a drive axle in all these buses. Two water-cooled asynchronous traction motors are located on each wheel in this electric portal axle. Special features: They are made without using rare earth elements and they obtain their complete power – 125 kW on each wheel, i.e. 250 kW in total or 340 HP – from relatively high revolutions.

HYBRID TECHNOLOGY IN LONG-DISTANCE TRAFFIC

The ZF TraXon automatic transmission system lets hybrid technology be used in long-distance traffic. In the TraXon Hybrid configuration, an electric motor is located in the clutch bell housing – this means that all hybrid functions can be used in heavy trucks: From the recuperation of braking energy, purely electric manoeuvring, switching off the engine at a standstill (start/stop function) to boosting the combustion engine. Especially attractive for many applications: The hybrid module can also be integrated during generator operation into the power supply of other units – for example, for refrigerated transports. In any case, the TraXon Hybrid contributes to reducing fuel consumption and emissions of trucks.
