Even if wheel loaders and other construction machines appear large and cumbersome, they must apply their force and power precisely in measured amounts. Here, the ZF driveline technology ensures the necessary sensitivity.
Movement sequences flow easier using continuously variable transmissions from ZF. Therefore, construction machines can be more precisely controlled. With gear shifting the drop in power associated with the change of gear does not occur. This ensures more constant engine speeds. Also the driver profits from the continuously variable technology, because manual gear shifting is no longer needed and he can completely concentrate on his work.
With the cPOWER ZF presented the first continuously variable transmission for construction machines. The complete driving range, forwards and in reverse, is controlled continuously variably with cPOWER. Low engine speeds ensure a high efficiency and the highest driving comfort irrespective of the traction speed. The power splitting continuously variable technology facilitates moving off softly and hydraulically. Furthermore, with the cPOWER a fuel saving of up to 25% can be achieved.
The new ECOMIX II transmission is about 50 percent smaller and 25 percent lighter in comparison to previous models. This allows vehicle manufacturers more flexibility in design and makes assembly easier. The unit is designed for transport mixers up to 16m³ drum capacities and its maximum input torque is 90,000 Nm.
The compact design of the ECOMIX II offers a wide range of further advantages: Thanks to an exceptionally rugged bearing concept it was possible to significantly increase the output bearing strength, which leads to less sensitivity in off-road operation.
Due to the new bearing concept the installation angle does no longer depend on drum size and drum filling. Installation angles of up to 20 degrees are possible throughout. Furthermore, mechanic and acoustic decoupling of drum and vehicle frame leads to smooth running, improved driving comfort and noise reduction.
Service-friendliness has also been improved. The ECOMIX II is easily accessible due to its compact design. Lifetime oil filling does not only save oil changes, it also protects the environment. A cassette-type sealing is used instead of the previous sealing collar, which makes the transmission more robust and increases service life.
With the EFFICIENCY PACKAGE ( download brochure (PDF, 8,0 MB) ) ZF is offering the system solution which perfectly matches the various components of a vehicle to one another. Transmissions, axle systems, and vehicle electronics are exactly tailored to the relevant requirements of the construction machine. In this way the various advantages of the individual components are combined. This increases not only the operating and driving comfort, but also improves the vehicle productivity substantially.
The figures speak for themselves.The options of the EFFICIENCY PACKAGE provide increased productivity and enhanced operating and riding comfort for the driver associated with a reduction of the operating and maintenance costs for the vehicle owner. Full utilization of the EFFICIENCY PACKAGE allows fuel savings of up to 15%. Increased comfort, higher productivity, reduced service costs and improved fuel efficiency are the further advantages.
The following modules belong to the EFFICIENCY PACKAGE:
