Problems solved by technology

However, even if the swing angle of the inertial mass body, that is, the amplitude of the vibration of the input torque is relatively small, the order of the vibration damping device is consistent with the order of the excitation of the engine, as the amplitude of the vibration of the input torque becomes larger, the vibration damping device There will also be a deviation between the order of the engine and the excitation order of the engine, so there is concern about changes in vibration damping performance

Embodiment Construction

[0030] Next, modes for implementing the invention of the present disclosure will be described with reference to the drawings.

[0031] figure 1 It is a schematic configuration diagram of the starting device 1 including the vibration damping device 20 of the present disclosure. The starting device 1 shown in this figure is mounted, for example, on a vehicle provided with an engine (internal combustion engine) EG as a driving device, and is used to transmit power from the engine EG to the drive shaft DS of the vehicle. The starting device 1 not only includes a vibration damping device 20, It also includes a front cover 3 as an input member connected to the crankshaft of the engine EG, a pump wheel (input side fluid transmission mechanism) 4 fixed to the front cover 3 and rotating integrally with the front cover 3, and a pump wheel 4 that can rotate coaxially with the pump wheel 4. Turbine (output side fluid transmission mechanism) 5, fixed to the input shaft of automatic transm...

Abstract

The present invention provides a vibration damping device. The vibration damping device (20) includes: a crank member (22) capable of swinging with the rotation of the drive member (15) to which torque from the engine (EG) is transmitted; and an inertial mass body (23 ), which is connected to the driving part (15) via the crank part (22), and swings around the center of rotation (RC) in conjunction with the rotation of the driving part (15) and the crank part (22), and the vibration damping device (20) Designed as, the effective order (q eff ) becomes larger as the amplitude of the vibration of the input torque transmitted from the engine (EG) to the drive member (15) becomes larger.

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 supporting member and the restoring force generating member swing in conjunction with each other. Background technique [0002] In the past, as such a vibration damping device, there is known a vibration damping device comprising: a flywheel mass body that receives centrifugal force and functions as a restoring force generating member; body connection (for example, refer to Patent Document 1). In such a vibration damping device, when the flywheel mass body swings with the rotation of the support member, the inertial mass body swings in conjunction with this, and the vibration of the support member can be attenuated by the vibration transmitted from the inertial mass ...
