Title:
TORQUE VARIATION ABSORPTION DAMPER
Document Type and Number:
Japanese Patent JP2017015227
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a torque variation absorption damper having a structure which can easily set a spring constant of damper rubber high, and can easily set a spring constant of coupling rubber low, in the serial-type torque variation absorption damper in which the damper rubber of a damper part and the coupling rubber of a coupling part are connected to each in series.SOLUTION: Damper rubber is arranged at an external peripheral side rather than coupling rubber, and the coupling rubber is arranged at an internal peripheral side rather than the damper rubber. The damper rubber is arranged at an internal peripheral side of a cylinder part of a hub, a damper mass is arranged at an internal peripheral side of the damper rubber, the damper mass integrally has an external peripheral cylinder part which is connected to the damper rubber, an end face part and an internal peripheral cylinder part, and the coupling rubber is arranged at an external peripheral side of an internal peripheral cylinder part being an internal peripheral side of the external peripheral cylinder part at the damper mass.SELECTED DRAWING: Figure 1
