Embodiment Construction

[0018] Next, the present invention will be described more specifically. The vibration damping device according to the present invention can be configured integrally with a rotating shaft or a rotating body that rotates when torque generated by a driving force source is input. The vibration attenuating device can be composed of the following components as main constituent elements: an inertial body that absorbs or attenuates torsional vibration generated by a rotating shaft or a rotating body through inertial force; an elastic vibration reducing mechanism that The elastic vibration reduction mechanism absorbs or attenuates torsional vibration through the elastic force of the elastic component; reciprocating motion to absorb or damp torsional vibration; and a torque limiting mechanism that limits torque transmission when torque input to a rotating shaft or rotating body increases to a certain extent. In the present invention, the vibration reducing device having the above-menti...

Abstract

Provided is a vibration damping device capable of suppressing variations in the degree of reciprocating movement of a pendulum which is caused by variations in the rotational center of the vibration damping device. The vibration damping device is equipped with a pendulum vibration damping mechanism (11) that includes a mass body (10) that moves in a pendular manner in response to torsional vibrations to dampen the torsional vibrations. An inertial body (4) is provided on the drive power source side of rotation shafts (2, 3). An elastic vibration reducing mechanism (5) is capable of transmitting power to the inertial body (4) and provided more toward the transmission side than the inertial body (4). The pendulum vibration damping mechanism (11) is capable of transmitting power to the elastic vibration reducing mechanism (5) and provided more toward the transmission side than the elastic vibration reducing mechanism (5). A torque limiter mechanism (14) is capable of transmitting power to the pendulum vibration damping mechanism (11) and provided more toward the transmission side than the pendulum vibration damping mechanism (11).

Description

technical field [0001] The present invention relates to a vibration damping device mounted on a rotating member for damping a torque variation input to the rotating member and torsional vibration caused by the torque variation. Background technique [0002] There is known a vibration damping device which is mounted on rotating parts such as a crankshaft of an engine of a vehicle, an input shaft or a drive shaft of a transmission, etc., which generate torque changes or torsional vibrations caused by torque changes, thereby absorbing or This torque variation or torsional vibration is attenuated. An example of the above-mentioned vibration damping device is described in Japanese Patent Application Laid-Open No. 2002-13547. [0003] The vibration damping device described in Japanese Patent Laid-Open No. 2002-13547 is provided on a rotating shaft between an engine and a transmission that changes the speed of power generated by the engine. The rotating shaft includes an output s...
