Torsional vibration dampers

Fixed to the crankshaft, the name of the torsional vibration damper explains its function, which is to absorb the torsional vibrations induced on the crankshaft by the pressures inside the combustion chamber. The torsional vibration damper is essential to preserve the functionality and life of the car's main transmission component, so much so that a good damper can absorb up to 50% of the vibrations produced on the crankshaft. AGLA produces rubber dampers and viscous dampers, which differ essentially in their operating temperature: rubber dampers (divided into primary and secondary, depending on whether the transmission of movement occurs rigidly between the crankshaft and the belt or through the rubber) are perfect for engines with relatively small capacity, which do not work at very high temperatures, while viscous dampers are used for high performance engines (trucks and large capacity cars), where the operating temperatures are too high for rubber. In these cases the absorption of vibrations is achieved by a silicone oil that guarantees durability and resistance for over 2 million km. AGLA produces an average of almost 4 million torsional vibration dampers a year.
