Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/171871
Kind Code:
A1
Abstract:
Provided is a power transmission device equipped with a pendulum damper capable of obtaining an intended vibration-damping performance by increasing the moment of inertia of a rolling element relative to the moment of inertia of the member on which the rolling element is installed. A power transmission device provided with: a fluid power transmission device that has a fluid path that transmits power between an input side member and an output side member via a fluid and a direct connection path that transmits power by engaging a lock-up clutch and directly coupling the input side member with the output side member; a pendulum damper that has a rolling element, which undergoes reciprocating motion in response to twisting vibrations of the output side member or a rotating body integrated thereto and damps the twisting vibrations; and an elastic damper that damps twisting vibrations by the relative rotation of a driver side member and a follower side member that are connected via an elastic body so as to allow relative rotation. In the power transmission device, the lock-up clutch and/or the elastic damper is provided on the output side of the pendulum damper, which is provided in series with the lock-up clutch on the direct connection path.
