Embodiment Construction

[0021] Next, modes for implementing the invention of the present disclosure will be described with reference to the drawings.

[0022] figure 1 It is a schematic configuration diagram of the starting device 1 provided with the vibration damping device 20 of the present disclosure. As shown in the figure, the starting device 1 is mounted on a vehicle, for example. The vehicle is provided with an engine (internal combustion engine) EG as a driving device. A front cover 3, a torque converter (fluid transmission) TC, a damper hub 7 as an output member fixed to an input shaft IS of a transmission (power transmission) TM, a lock-up clutch 8, a damper 10, and the like. Here, the torque converter TC includes: a pump wheel (input side fluid transmission element) 4 fixed to the front cover 3 and rotating integrally with the front cover 3; The shaft rotates and is fixed to the driven part 15 of the damper device 10; the stator 6, which rectifies the flow of working oil (working fluid) ...

Abstract

The invention aims to improve vibration-damping performance. This vibration-damping device is provided with a concave-surface-shaped guide surface 23 formed in a support member 21 so as to curve toward the outer periphery of the support member 21, a mass object 30 that rolls over the guide surface 23 while being pushed against the guide surface 23 by centrifugal force accompanying the rotation ofthe support member 21, and an inertia ring 40 that is rotatably linked to the mass object 30 and that swings around the rotational center of the support member 21. When in a state of equilibrium, thecenter of gravity of the mass object 30 is positioned farther radially outward than is the position where the mass object 30 and the inertia ring 40 are linked. When the support member 21 rotates, theinertia ring 40 swings relative to the support member 21 around the rotational center of the support member 21, and the mass object 30 rolls over the guide surface 23.

Description

technical field [0001] The present disclosure relates to vibration damping devices. Background technique [0002] Conventionally, as a vibration damping device, a constant frequency type dynamic damper including an annular weight and a flyweight attached to a rotating body driven while receiving a fluctuating torque has been proposed (for example, refer to Patent Document 1). This constant frequency type dynamic shock absorber has an interlocking mechanism. The interlocking mechanism is composed of a cam surface formed on an annular weight and a roller portion provided on a flyweight. If the flyweight moves radially outward due to centrifugal force, Then the roller portion comes into contact with the cam surface. As a result, the flyweight slides or rolls within a predetermined range limited in the radial direction by the guide groove relative to the rotating body, and the ring weight rolls (swings) coaxially with the rotating body at least within a limited predetermined ra...
