Electrification
ELECTRIFICATION
The trend towards electromobility is not confined to passenger cars. Thanks to ZF technology, work on urban construction sites and in buildings will also be possible in the future - despite strict standards concerning emissions: ZF takes care of climate-friendly operation, neutral in terms of CO₂ emissions and offers E-Mobily Solutions for various applications.
Electric Compact Vehicles
Emission-free and eco-friendly
Guided by the principle of zero emissions, ZF strives to enable compact work machinery to operate completely emission-free in the future.
Being a systems supplier, ZF not only delivers the unit, but offers a combination of front and rear axles, drives, inverters and electric Drive Control Unit.
eTRAC
Electric Central Drive
The electrified eTRAC driveline system with its 48-volt electric motor developed by ZF provides the necessary emission-free drive.
Advantages:
- A "best in class solution" for power density in compact loaders
- Unrivalled on the market in the 20 kW (continuous performance) and 48 V performance classes
- Use of liquid coolant in the traction motor and power electronics ensures continued performance in construction machinery applications
With eTRAC, ZF sets new standards for electric drives for construction machinery.
The electric transfer case eAVG is suitable for all three performance classes with a continuous output of 20, 30 or 42 kW.
The liquid cooled e-motor is highly efficient. Its robust design makes it the ideal choice for off-highway applications.
Electric motor with flange-mounted electric transfer case eAVG.
