Problems solved by technology

However, the method described in Patent Document 1 lacks theoretical support. According to the research of the present inventors, it is clear that viscous resistance in the presence of liquid such as working oil has little influence on the swing of the mass body.
Therefore, even if the vibration order of the mass body in the centrifugal vibrator type vibration absorbing device is set as described in Patent Document 1, the vibration absorbing performance of the centrifugal vibrator type vibration absorbing device cannot be improved, and the vibration absorbing performance may be reduced in some cases. reduce

Embodiment Construction

[0016] Next, a method for implementing the present invention will be described with reference to the drawings.

[0017] figure 1 It is a schematic configuration diagram of a starter device 1 including a centrifugal vibrator-type vibration absorbing device 10 according to an embodiment of the present invention. The starter device 1 shown in the figure is mounted on a vehicle equipped with an engine (internal combustion engine) as a driving device, and transmits power from the engine to a transmission as an automatic transmission (AT) or a continuously variable transmission (CVT). In addition to the centrifugal vibrator type vibration absorbing device 10, the starting device 1 also includes: a front cover (input part) 3 connected to the crankshaft of the engine; a pump wheel (input side fluid transmission member) 4 fixed to the front cover 3; A runner (output-side fluid transmission member) 5 that rotates coaxially with the wheel 4; a guide wheel 6 that rectifies the flow of worki...

Abstract

A centrifugal pendulum-type vibration absorbing device includes a support member that is coupled to a driven member that is a rotary element that rotates by means of power from an engine and a mass body that is coupled to the support member so as to oscillate about a pendulum fulcrum PF and is designed so as to have an effective order qeff that is greater by a correction amount Δq that is at least associated with the non-linearity of an order q of vibration of the centrifugal pendulum-type vibration absorbing device that is dependent on an oscillation angle φ of the mass body than an order qtag of vibration that is generated in the engine to be damped.

Description

Technical field [0001] The present invention relates to a centrifugal vibrator-type vibration absorbing device including a support member connected to a rotating member that rotates by power from a driving device, and a mass body connected to the support member and swinging around a vibrator fulcrum, and an order setting method thereof. Background technique [0002] Conventionally, as a force transmission device equipped with such a centrifugal vibrator type vibration absorbing device, the following devices are known: including at least one input body, an output body, a vibration damping device arranged in at least a part of a room that can be filled with a working medium, particularly oil, and The centrifugal vibrator-type rotational speed adaptive dynamic vibration absorber connected to this vibration damping device transmits power between the driving device and the driven device (for example, refer to Patent Document 1). In this force transmission device, in association with t...
