Embodiment Construction

[0022] Next, modes for implementing the invention of the present disclosure will be described with reference to the drawings.

[0023] figure 1 It is a schematic configuration diagram of the starting device 1 including the shock absorber device 10 of the present disclosure. The starting device 1 shown in this figure is mounted, for example, on a vehicle equipped with an engine (internal combustion engine) EG as a driving device, and includes, in addition to a shock absorber 10 having a four-link type shock absorber 20 as a vibration damping device, the following: The front cover 3 as an input member connected to the crankshaft (output shaft) of the engine EG, the pump impeller (input side fluid transmission element) 4 fixed to the front cover 3 and rotating integrally with the front cover 3, and the pump impeller 4 can be coaxial The ground-rotating turbine (output side fluid transmission element) 5, the input of the transmission (power transmission device) TM in an automatic...

Abstract

A shock absorber. The four-link vibration absorbing device (20) includes: connected to the driven member (15) of the shock absorbing device via the connecting shaft (A1), and can swing around the connecting shaft (A1) as the driven member (15) rotates The crank part (21); and the mass that is connected to the driven member (15) via the crank part (21) and is linked with the crank part (21) with the rotation of the driven member (15) to swing around the rotation center RC The body (23), the driven member (15) and the turbine of the fluid transmission device are connected to rotate integrally.

Description

technical field [0001] The disclosed invention relates to a damper device including at least an input element and an output element. Background technique [0002] Conventionally, as a dynamic shock absorber, there is known a link mechanism including a first link connected to a crankshaft of an internal combustion engine, a second link connected to the first link, and a link mechanism connected to the second link and via A link mechanism is a device of an annular inertial body coupled so as to be rotatable relative to a crankshaft only at a predetermined angle (for example, refer to Patent Document 2). In this dynamic damper, the connection point between the crankshaft and the first link is separated in the circumferential direction from the connection point between the inertial body and the second link, and a mass body is formed on the first link. Furthermore, in this dynamic damper, when the crankshaft rotates, centrifugal force acts on the first link and the second link o...
