The technology
Torque converters from ZF feature superior performance density for torsional dampers and hydrodynamic circuits as well as adaptable lock-up clutches and variable damping systems. Compared to conventional converters, the lock-up clutch of a torque converter equipped with the new twin-torsional damper TwinTD can be applied very early on, which improves driving comfort especially at low engine speeds. This feature of the new twin-torsional damper also significantly reduces fuel consumption.
Comparison of vibration damping
Compared with conventional torque converters, the new twin-torsional torque converter significantly reduces engine irregularities, even at low rotational speeds. This is why gears can be changed earlier with no impact on driving comfort and dynamics.
An example for the reduction in fuel consumption
The torsional damping system minimizes torsional vibrations to such an extent that early shift points are possible, with a consequent reduction in fuel consumption.
