Abstract
A four-bar linkage vibration absorbing device includes: crank members each coupled to a driven member of a damper device via a coupling shaft and each capable of swinging about the coupling shaft when the driven member is rotated; and a mass body that is coupled to the driven member via the crank members and that swings about the rotation center RC together with the crank members when the driven member is rotated. The driven member is coupled to a turbine runner of a hydraulic transmission device so as to rotate with the turbine runner.
Claims19
A damper device including an input element to which torque from an engine is transmitted, an intermediate element, an output element, a first elastic body that transmits the torque between the input element and the intermediate element, and a second elastic body that transmits the torque between the intermediate element and the output element, comprising:
- a vibration damping device including a support member that coaxially rotates with the intermediate element or the output element, a restoring force generating member that is coupled to the support member via a coupling shaft and that can swing about the coupling shaft when the support member is rotated, and an inertial mass body that is coupled to the support member via the restoring force generating member and that swings about a rotation center of the support member together with the restoring force generating member when the support member is rotated.
