ZF in Wheel Loaders
The ZF Powertrain management provides the efficiency which is required under any working condition.
Wheel loaders are amongst the most purchased and technically the most demanding off-road vehicles. An intelligent driveline system always makes the power available where it is needed. There is great value in ZF innovations. They produce advantages in equal measures for the driver, operator and manufacturer. Topics such as consumption savings, comfort or ecological compatibility are of increasing importance with con?struction machines and construction site vehicles.
ZF is decisive in pushing development forward in driveline and chassis technology, a renowned specialist for driveline technology and recognised worldwide as innovative system supplier for off-road machinery. The demands on these vehicle types are high: fast work with millimetre accuracy and the highest productivity combined with reduced operating costs. ZF underlines its systems competence with the efficiency package which includes many benefits due to perfectly matched components. The field of application mainly comprises the important wheel loader, dump truck, diesel and gas lift truck market.
The options of the efficiency package provide increased productivity and enhanced operating and driving comfort for the operator associated with a reduction of the operating and maintenance costs for the vehicle owner. Full utilisation of the efficiency package allows fuel savings of up to 20 per cent. For many years already, ZF driveline and chassis systems have proven themselves in meeting the challenges of the market. With the efficiency package, ZF consolidates its competence in the transmission, axle and software development, thus offering more than the sum of individual advantages. This approach makes it possible to reconcile the frequently conflicting demands for enhanced comfort, increased productivity, less consumption, and reduced component wear.
Efficiency Package
ZF Ergopower: This proven and tested fully automatic powershift transmission system has been optimised for different construction machinery types and offers the innovative feature of five instead of four gears. Therefore, the noise-optimised transmission allows even more comfortable and easier handling, high shifting quality and flexibility. Moreover, the operating costs can be further reduced. The ZF Ergopower provides additional possibilities for connecting an electronic driveline management, thus enabling vehicle specific controls.
ZF Ergolockup: The Ergolockup ensures that at low speeds already the Ergopower converter lock-up clutch is applied by modulation via the software. The optimum effect of this function is of particular benefit to transmissions with five gears, since in this case the converter lock-up clutch can be kept closed when shifting gears.
Depending on the application conditions, the fuel consumption can be reduced by 10 to 15 per cent. This corresponds depending on the operation conditions with a saving of approx 2.5 litre/hr. Considering an average annual performance of 2,000 operating hours and a fleet of 10 vehicles. This means 50,000 litre of fuel saving per year. In addition, a lower engine speed further reduces the noise emission and improves the lifetime. Because of the lock up we increase the tractive effort in the different gears and additionally the maximum speed of the machine. For this reason the productivity is improved considerably.
ZF Ergotraction
This feature for axle control offers a differential lock management which governs the interwheel differential locks in wheel loaders and the inter-axle differential locks in articulated dump trucks. The Ergopower transmission control provides automatic engagement and disengagement of the powershift differentials.
Previously, the differential locks were only engaged depending on the operator. Today, they are always engaged unless they would disturb the operation. No manual actuation is required.
This innovation protects the drive system components and the tires whilst offering a hundred per cent tractive effort. It also contributes to a significant fuel saving. Moreover, Ergotraction improves cross-country mobility and increases the performance. Vehicle handling is more comfortable and easy. Protection against maloperation is also guaranteed.
ZF Powerinch
The Powerinch dynamically adjusts the clutch cutoff point depending on transmission output torque and brake pressure. It enables the vehicle drawbar pull via the brake pedal, independent of engine speed.
The Powerinch is an advanced driveline management feature to improve loader application such as truck loading and tight corner operation by limiting vehicle tractive effort in hydraulic stall conditions to the minimum required to hold the vehicle and not to the maximum available.
Reduced fuel consumption: reduced power loss in the torque converter, and reduced energy dissipation in the axle service brake
Improved productivity: provides more power to the vehicle hydraulics, ensures smooth control at high engine rpm and low vehicle speed, and allows better handling of the vehicle.
The Ergolockup ensures that at low speeds already the Ergopower converter lock-up clutch is applied by modulation via the software.
Advantages
Up to 20 per cent less fuel.
Up to 40 per cent more productivity.
ZF multi-track wheel loader axle now localised for the Indian market.
ZF converter lock up clutch and other components of the ZF efficiency package increase fuel savings reduce emissions and extend lifetime.
The easy handling of ZF fully automatic transmissions and high-tech axle systems support the driver in all working situations, which means a significant increase of productivity and that is what pays off at the end.
ZF has successfully started its local production of its MTL range of axles for catering wheel loader segments up to 12 T vehicle weight range. The said axle comes with following features: modular design, easy serviceability, inboard multi-disc braking, and higher cooling efficiencies limited slip differential, specially designed for off-road applications.
