Hybrid solutions and various types of energy-efficient all-electric drives reduce pollutant and noise emissions in city and intercity buses, which entitles them to enter the green zones in the cities.
The AxTrax AVE electric portal axle is ideally suited to various drive concepts for city buses: whether as a serial hybrid, all-electric drive powered by a fuel cell or battery, or from the trolley wire. The increased use of brake energy or - in combination with hybrid drives - the use of smaller combustion engines helps to considerably reduce fuel consumption and emission of pollutants in comparison to conventional concepts. Lane-independent, zero-emission driving is now also achievable in the city. This enormously increases cost-effectiveness and availability for use.
Each wheel is driven by a compact, high-speed, liquid-cooled asynchronous motor to keep the axle weight including the integrated motors low. As no separate engine or propshaft are required, this reduces the amount of space required and the vehicle's weight. The extra space allows room for a more powerful battery or an upgrade of the vehicle's interior in order to transport more passengers.
No special wheel components are required with the AxTrax AVE. The tire-rim combinations used in normal buses as well as the standard disk brakes can both be used. The brakes are fitted in the same low-maintenance position as with the standard axles.
