Embodiment Construction

[0026] Next, modes for implementing the invention of the present disclosure will be described with reference to the drawings.

[0027] figure 1 is a schematic configuration diagram showing a starting device 1 including a vibration damping device 10 of the present disclosure, figure 2 is a cross-sectional view showing the vibration damping device 10 . figure 1 The starting device 1 shown is mounted on a vehicle including an engine (in this embodiment, an internal combustion engine) EG as a prime mover. In addition to the vibration damper 10, the starting device 1 also includes a front cover connected to the crankshaft of the engine EG. 3. The pump wheel (input side fluid transmission member) 4 fixed to the front cover 3, the turbine wheel (output side fluid transmission member) 5 that can rotate coaxially with the pump wheel 4, is connected to the vibration damping device 10 and fixed to the motor as an automatic Transmission (AT), continuously variable transmission (CVT), d...

Abstract

This damper device is provided with: an input element to which motive power from an engine is transmitted; an output element; a first torque transmission path including an intermediate element, a first elastic body for transmitting torque between the input element and the intermediate element, and a second elastic body for transmitting torque between the intermediate element and the output element; and a second torque transmission path including a third elastic body for transmitting torque between the input element and the output element. The intermediate element includes: a first plate memberwhich is provided with a torque transmission part disposed so as to extend between the first and second elastic bodies in the radial direction of the damper device, said first plate member supportingat least ends of the first and second elastic bodies from the outside in the radial direction; and a second plate member provided with a coupling part which is disposed between the first and second elastic bodies, and which is fitted to the torque transmission part of the first plate member, said second plate member being coupled to a mass body.

Description

technical field [0001] The disclosed invention relates to a vibration damping device having an input member and an output member to which torque from an engine is transmitted. Background technique [0002] Conventionally, as such a damper device, a two-channel damper used in connection with a torque converter is known (for example, refer to Patent Document 1). In the damping device, the vibration path from the engine and the lock-up clutch (32) to the output hub (37) is divided into two parallel vibration paths B and C, each of which has a A pair of springs and a separate intermediate flange (36, 38) disposed between the pair of springs. In addition, in order to make the natural frequencies of the two vibration paths different, the turbine (34) of the torque converter is combined with the middle flange (36) of the vibration path B, and the natural frequency of the middle flange (36) of the vibration path B is smaller than that of the vibration path The natural frequency of...
