Hybrid Technology
Combining the best of two worlds
ZF can support shipbuilders and fleet operators who want to lower their emissions, fuel consumption and operating costs with a hybrid-capable transmission portfolio in many application segments. In so doing, the ZF Group offers fully integrated transmissions, electric motors, inverters and control components, which further increases reliability, profitability and quality.
There are many arguments in favor of maritime hybrid propulsion systems: less noise and exhaust gases, but more fuel savings and more effective power delivery during slow speed maneuvering. Starting in 2020, stricter environmental regulations and laws will apply to the oceans. In electric mode, hybrid vessels may continue to drive to ports and waters that are closed to purely conventional vessels. Manufacturers and operators alike benefit from the broad portfolio of hybrid-ready transmissions that ZF offers for almost all application segments. To this end, the company is expanding its gearboxes with an additional power take-in (PTI), via which an electric machine alone or in conjunction with the conventional power unit drives the propeller shaft. This auxiliary drive can serve a variety of ratios. An optional helical gearbox compensates for differences in speed between the main unit and the electric motor.
Hybrid-Capable Marine Transmissions
Emission-free power with ZF CeTrax
The electric drive ZF CeTrax enables shipbuilders to pursue a hybrid platform strategy for the driveline with the transmission and electric motor coming from one source. CeTrax is already proven in other applications on land and has been adapted for maritime use in conjunction with powerful hybrid transmissions. The combination of these two innovative technologies in one propulsion system guarantees perfect interaction and optimum power delivery.
New and highly flexible transmission series ZF 8000
With the ZF 8000 series, ZF is presenting a brand-new marine transmission family for a power range up to 3,000 kW. The availability of multiple gear ratios, housing sizes and variants gives manufacturers high flexibility for new designs and retrofits. Thus, the ZF 8000 series covers a wide range of applications, from coast guard ships and yachts to ferries, supply vessels and small tankers.
