Fluid Torsional Vibration Dampers
Designed for when loads, damping and thermal load capacity are high
Designed for when loads, damping and thermal load capacity are high
In Fluid TVDs, the fluid provides the damping and stiffness whereas the inertia ring serves as the vibration mass. Specially designed bearings enable relative movement of the torsional vibration damper and the optional pulley secures the connection to the belt drive.
About Torsional Vibration Dampers
Torsional Vibration Dampers absorb rotational vibrations in internal combustion engines. The dampers are particularly effective in conjunction with decoupled pulleys, which keep crankshaft irregularities away from the belt drive and auxiliaries. In fuel-efficient start-stop systems, they eliminate the effects of an engine that is constantly starting and stopping. With an additional one-way-clutch feature, they can enable further savings in fuel consumption and CO2 emissions.

Light vehicle manufacturers are being increasingly challenged to downsize components to reach ambitious global targets for fuel consumption and CO2 emissions. The result is smaller engines with fewer cylinders that compensate for reduced capacity by building up increased pressure and enabling more efficient combustion. This generates stronger vibrations in the crankshaft. Torsional vibration dampers compensate rotational vibrations in the engine and the irregularities of the crankshaft are kept away from the belt drive, also ensuring optimized durability.
Torsional Vibration Dampers are offered in a wide range of processes and in a variety of materials – from pressed, high torque, vulcanized and fluid torsional vibration dampers, through damper isolator pulleys with an overrunning feature, to sprocket dampers.
