CRANK DAMPER PULLEY STRUCTURE FOR VEHICLE

摘要

PURPOSE:To absorb the low order bending vibration while suppressing by providing a dynamic damper against the bending vibration through utilization of the space of drum section in front of pulley hab in addition to a torsional damper against the torsional vibration. CONSTITUTION:A damper mass 5 and a damper rubber 6 are secured to form a torsional damper 7 against the torsional vibration of crank sahft 1 to the outside of pulley hab 3. A damper supporter 8 is pressure inserted and fixed in the drum section A at the set bolt 2 side of pulley hab 3 where a damper rubber 9 and a damper mass 10 are secured while being laminated in axial direction. Consequently, the low order bending vibration such as single node or double node bending is suppressed and absorbed through the damper rubber 9 and the damper mass 10.
