Document Type and Number:
WIPO Patent Application WO/2012/043302
Kind Code:
A1
Abstract:
The disclosed hydraulic power transmission (1) is provided with: a damper mechanism (8) having a drive member (80), an intermediate member (83) engaging with the drive member (80) via a first coil spring (81), and a driven plate (84) engaging with the intermediate member (83) via a second coil spring (82); a dynamic damper (10) configured from a coil spring (100) and a turbine runner (5) as a mass body; and a centrifugal pendulum absorber device (20) including a support member (21) and multiple mass bodies (22) capable of vibration relative to the support member (21). The coil spring (100) of the dynamic damper (10) engages with the driven plate (84) of the damper mechanism (8), and the support member (21) of the centrifugal pendulum absorber device (20) is connected to the intermediate member (83) of the damper mechanism (8).
