Torque Converter
More Comfort and Less Fuel Consumption
Advantages
- Greater degree of efficiency
- High hydrodynamic power density
- High-performance comfort lock-up clutch
- Optimum vibrational decoupling
Benefits
Because loss due to slippage occurs in purely hydrodynamic transmission systems, controlling and regulating these hydrodynamic processes represent a crucial factor for converter efficiency, in addition to a high-performance converter lock-up clutch.
Torque converters from ZF feature optimum hydrodynamic efficiency. The lock-up clutch, a rigid connection between the impeller and the turbine rotor, ensures that the slippage of the hydrodynamic operation is eliminated and that engine power is transmitted to the drive train without any loss. Maintaining efficiency in this way at higher rpm levels helps to reduce fuel consumption. However, a closed lock-up clutch no longer features the outstanding vibration damping properties of a hydrodynamic system – this task can be performed instead by a torsional damper tuned to the requirements of the respective powertrain.
Function
Newly developed economical characteristics ensure improved, more comfortable acceleration. The converter can be used for engine torques up to 2,000 Nm.
Additional Information
Thanks to the optimum heat dissipation of the single-sided multisegment facings, higher engine torques can be transmitted. Four or six lamellae are available, depending on requirements.
