Title:
Fluid type power transmission device
Document Type and Number:
Japanese Patent JP6182192
Kind Code:
B2
Abstract:
A fluid type power transmission device in which a torque transmission path for transmitting torque from a vehicular engine is provided with a dynamic damper mechanism formed by disposing a plurality of damper springs between an inertial rotating body and a rotation-transmitting member forming part of the torque transmission path. An elastic member always linked to one of the rotation-transmitting member and the inertial rotating body is added to the dynamic damper mechanism. Play occurs in a torque direction between the elastic member and the other of the rotation-transmitting member and the inertial rotating body at a time of low speed rotation, but the elastic member exhibits resilient force between the rotation-transmitting member and the inertial rotating body in response to deformation due to centrifugal force at a time of high speed rotation that is a predetermined rotational speed or greater.
