Document Type and Number:
Japanese Patent JP6260556
Kind Code:
B2
Abstract:
A torsional vibration damper that can be arranged in a fluid coupling to downsize a powertrain is provided. The torsional vibration damper has a mass body held in a rotary member in such a manner to be oscillated by torque pulse of the rotary member. The rotary member is arranged in an internal space of a fluid coupling in which a pump impeller, a turbine runner and a predetermined stationary member are held in a casing. A planetary unit that performs a differential action among three rotary elements is arranged in the casing. In the planetary unit, a first rotary element is connected to the stationary member, a second rotary element is connected to the rotary member, and a third rotary element is connected to the turbine runner.
