Enable lightweight crankshaft design and cost-efficient noise radiation reduction
Elastomer types provide excellent damping and stiffness characteristics. The inertia ring serves as the vibration mass for the pressed TVD. In many applications it provides the torque transmission to the auxiliary belt drive and with a special surface treatment it can be equipped with a high torque feature to support even high loaded applications. Pressed TVDs are a cost-effective way to achieve this goal.

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.
