Problems solved by technology

On the other hand, in the vibration damping device including the inertial mass body described in Patent Document 1, even if the order of the vibration that can be damped best by the vibration damping device coincides with the excitation order of the driving device, it may not be possible Good vibration damping performance is obtained, there is still room for improvement in terms of setting the order more appropriately to improve vibration damping performance

Embodiment Construction

[0029] Next, modes for implementing the invention of the present disclosure will be described with reference to the drawings.

[0030] 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 invention provides a vibration damping device and a design method therefor. The vibration damping device is disposed in an oil chamber and includes: a support member that rotates integrally with arotating element around the center of rotation of the rotating element to which the torque from an engine is transmitted; a restoring force generation member that is connected to the support member and can pivot along with the rotation of the support member; and an inertial mass body that is connected to the support member via the restoring force generation member and pivots around the center ofrotation in conjunction with the restoring force generation member, along with the rotation of the support member. The order of the vibration damping device is larger than the sum of the excitation order of the engine and an offset value taking into consideration the effect of oil inside the oil chamber, and a reference order, which is a convergence value of the order of the vibration damping device operating in the oil chamber when the amplitude of the vibration of the input torque transmitted to the rotating element becomes smaller, becomes larger than the excitation order.

Description

technical field [0001] The disclosed invention relates to a vibration damping device and a design method thereof. The vibration damping device includes: a restoring force generating member capable of swinging as the support member rotates; and an inertial mass body connected to the supporting member via the restoring force generating member. , and swings in conjunction with the rotation of the supporting member and the restoring force generating member. Background technique [0002] In the past, as such a vibration damping device, the following vibration damping device is known, that is, the vibration damping device includes: a flywheel mass body, which receives centrifugal force and functions as a restoring force generating member; and an annular inertial mass body, which is connected via a A rod is connected to this flywheel mass body (for example, refer to Patent Document 1). In such a vibration damping device, if the flywheel mass body swings with the rotation of the su...
