Vibration damping device

Abstract

The invention provides a vibration damping device. The vibration damping device has a support member rotating around the rotation center of a rotation element; a recovery force generation member coupled to the support member; an inertia mass body coupled to the support member via the recovery force generation member; a guided section provided in the recovery force generation member or the inertiamass body; and a guide section formed in the inertia mass body or the recovery force generation member, having the component of centrifugal force acting on the recovery force generation member from the guided section transmitted thereto, and guiding the guided section such that, when the support member rotates, the recovery force generation member swings along the radial direction relative to therotation center and the inertia mass body swings around the rotation center. The recovery force generation member includes two mass bodies coupled so as to face each other in the axial direction of the support member and arranged on both sides of the inertia mass body, in the axial direction.

Description

technical field [0001] The disclosed invention relates to a vibration damping device including: a restoring force generating member capable of swinging as the supporting member rotates; and an inertial mass body connected to the supporting member via the restoring force generating member and The rotation of the member swings in conjunction with the restoring force generating member. Background technique [0002] Conventionally, as a torque fluctuation suppressing device for suppressing torque fluctuation of a rotating body to which torque from an engine is input is known, a mass body is arranged in alignment with the rotating body in the axial direction, and is arranged to rotate relative to the rotating body. freely; the spinner, which is arranged to be able to move in the radial direction in the concave part formed in the spinner by being subjected to the centrifugal force generated by the rotation of the spinner and the mass body; The cam of any one of the body and the m...

Problems solved by technology

In addition, at this time, there is concern that the degree of freedom in setting the shape of the centrifuge and the position of the center of gravity will decrease, and it will be difficult to match the order of the torque fluctuation suppression device with the order of excitation of the engine.

Therefore, in the above-mentioned conventional torque fluctuation suppressing device, it is also worried that it is difficult to ensure the weight of the centrifuge sufficiently to further increase the centrifugal force acting on the centrifuge, so that a good vibration damping effect cannot be obtained.
