Torque for Any Given Application

What applies to commercial vehicles in general, is also valid for the special area of construction machinery: Requirements for vehicles are on the rise. Supposedly, they must be versatile, economically viable, and reliable while, naturally, they should be saving fuel in parallel. With its highly efficient and individually adaptable torque converters, ZF Friedrichshafen AG is successfully bridging this gap for its respective scope of responsibility.

Millimeter-precise accuracy for maneuvering, swift loading and unloading, a high and even level of power transfer, as well as quick and smooth shift processes: Construction machinery must be highly versatile and reliable. And this more than ever! So that wheel loaders, dumpers, backhoe loaders, or telescopic handlers can successfully complete the tasks assigned by the respective owner/driver, all components of the driveline must be optimally harmonized with one another. Today, no one may imagine to work without the precious assistance granted by vehicles equipped with hydrodynamic torque converter. They move heavy weights which a conventional clutch would be unable to cope with.

Here, the torque converters by ZF are particularly flexible: Depending on the engine’s characteristics, the transmission’s grading, and the type of machinery, hydraulic configurations vary. With hydrodynamic diameters of 280 up to 440 millimeters, torque converters by ZF can easily be used for maximum torque transfers of 500 up to 2,700 Nm. Thus, we are not only covering the entire torque range of construction machinery, but we can practically fulfill all individual requirements and requests of manufacturers and operators. Moreover, the compact and weight optimized design enabled by metal-shaping technology as well as the geometries of the oil circuit ensure maximum flexibility in the fields of vehicle peripheries. Thanks to individual adaptation of performance and model design to the respective application, the torque converters warrant top efficiency.

Since any kind of hydrodynamic power transfer generates high levels of fuel consumption, it must only be used where explicitly required. Therefore, after the setting-off process, a converter lock-up clutch ensures that the torque flow between the engine and the transmission takes place in a direct and thus loss-free way. This design makes a considerable contribution to fuel consumption reduction and the economic viability of construction machinery. In order to live up to today's highly dynamic shift sequence requirements for transmissions, new freewheel concepts are applied to torque converters.

Research in the fields of hydrodynamics, the further development of lock-up clutches, as well as close cooperation with vehicle manufacturers and transmission producers have made ZF the leading European manufacturer of torque converters.
