In line with the maxim “Vision Zero”, ZF’s objective is to reduce not only accidents and downtimes due to failures, but also emissions to zero. Above all in the agricultural field, this target is always linked to a sustainable increase in productivity. ZF supplies complete electrification systems for agricultural machinery manufacturers from one source, offering a broad range of hybrid and all-electric drive solutions for almost every vehicle segment.
Electrification for tractors
Electrified CVT transmissions for tractors
eTERRAMATIC eCVT
The functional integration of the electric power take-off (ePTO) into an electrified drivetrain supports both vehicle integration and system design. The variator, consisting of two electric machines, is responsible for both the drive and thus for controlling the transmission ratio, as well as for generator functionality.
Electric-hydrostatic CVT Technology
eTERRAMATIC eTMG-Series
With the eTERRAMATIC axle drive, ZF is presenting a fully electrified hydrostatic CVT drive technology for BEV or FEV vehicle architectures. The modular principle, comparable to the conventional TERRAMATIC series, enables easy integration into today's vehicle architecture. The eTERRAMATIC eTMG series offers the same driving performance and functionality as the current TERRAMATIC series, including the control of all power take-offs or the mechanical PTO as well as the integration of all HMI and CU components into the existing vehicle architecture.
Fully electrified drivetrain
eTERRADRIVE eTD-Series
ZF presents the fully electric transaxle eTERRADRIVE, marking a significant step towards zero-emission agricultural machinery. The modular and highly integrated transaxle system for agricultural tractors from 60 to 100 kW combines traction, power take-offs (agricultural mechanical PTO and working hydraulics), and rear lift in one compact unit and is specifically designed for battery-electric vehicle architectures (BEV).
Electrification for implements and trailers
Systems with electric traction drives on implements can support traction on loose ground. Electrically distributed traction management enables different agricultural system concepts. The modular drive system has been developed to allow common components and interfaces to be used across different applications.
Electric single-wheel drive
eTRAC eTDW
- Compact high integration motor design
- Dual motor cooling system (air, water-glycol)
- Integrated brake control system
Advantages
- Increased productivity thanks to potentially larger work equipment
- Higher constant driving and working process speed
- Traction management for different operating conditions
Electrification for yard applications
Electric drive systems for compact vehicles such as yard loaders and telehandlers extend the possibilities of electric vehicle concepts in agricultural and municipal applications. Typical characteristics include locally CO2 emission-free operation and reduced noise levels in indoor and outdoor environments, compared to ICE concepts.
Electrification for field robots
The ZF eTRAC electric traction drive forms the technological basis for a range of possible applications among others including field robots.
The transmission series GK can be used to drive and, if required, steer smaller field robots on all wheels. The technology is derived from ZF forklift applications, has been tried and tested over many years, and only needs to be adapted to off-road requirements.
For larger self-propelled vehicles, ZF offers wheel drives from the eTDW and GP transmission series. Similar to counterbalanced trucks in the logistics sector, field robots are moved and controlled by counter-rotating wheel motors.
