{p_product_name} by {p_product_company}


The clutch disk is installed in the powertrain between flywheel and pressure plate.

The clutch disc has an integrated torsional damper to optimize the torsional vibrations properties, designed to increase the comfort for the driver and minimize the stress for the entire powertrain.

The demands placed on modern clutch systems are high: rapid and reliable disengagement and engagement of the torque flow, pleasant and ergonomic operation, maximum service life without loss of comfort, and vibrational damping using the smallest possible installation space.

The torsional damper integrated in the clutch disc is the main element for adjusting torsional rotation properties throughout the powertrain, from the combustion engine to the wheels. This effective vibrational damping system consists of a friction unit and spring sets for both driving and idling. Coil springs positioned in windows allow a limited degree of rotation between the crankshaft and the transmission input shaft. Torsional dampers are individually tuned because each engine/transmission aggregate has its own characteristics.
