Key Facts
Fuel-efficientUp to 20% lower fuel consumption compared to a hydrodynamic transmission*EconomicalReduced lifecycle costsComfortableTorque converter ensures smooth starting process
As a technological leader for modern driveline technology, ZF guarantees tangible customer value. Fuel savings, a long service life, and optimum shift comfort – those are the advantages of the powerful powershift transmission on the rail vehicle driveline technology market: EcoLife Rail 2.
Details
Technical information
The powershift transmission is based on the second generation of the successful EcoLife 2 bus transmission and has been adapted for railway traffic. The transmission is custom-tailored for diesel multiple units with a net engine output torque of up to 2,500 Nm. The torque converter ensures smooth starting processes and optimal acceleration values. The six mechanical gears keep the engine in an economical speed range. The integrated retarder considerably reduces wear in the mechanical brake system. System safety is ensured by the “Failsafe Principle”.
Benefits
- Compact installation space
- High performance density
- Integrated electronics
- Optimum power-to-weight ratio
- Ready for hybrid applications in rail vehicles
Repowering
ZF’s Repowering solutions aim at reducing fuel consumption and thus lifecycle costs as well as at extending the service life of the rail vehicles and providing them with higher acceleration. In the repowering process, outdated driveline technology is replaced by modern, efficiently working driveline components. The EcoLife Rail 2 powershift transmission can be applied for such Repowering projects.
*Fuel savings are based on a real-world comparative test conducted by a customer. Actual results may vary depending on vehicle configuration, route profile, engine, load, and operating conditions and cannot be guaranteed.
