Problems solved by technology

Therefore, in the two-channel shock absorber of Patent Document 1, there is a worrying situation in which the setting of the vibration path B by adjusting the rigidity (spring constant) of each spring and the weight (moment of inertia) of the intermediate flange The degree of freedom of the natural frequency of C and C decreases, making it difficult to improve the vibration damping performance
In addition, in the two-channel damper of Patent Document 1, there is also a worrying case where the resonance frequencies of the vibration paths B and C are close to each other, and a sufficient vibration damping effect cannot be obtained.

Abstract

A damper device (10) is configured in such a manner that a first torque transmission path (P1) and a second torque transmission path (P2) which is provided in parallel with the first torque transmission path (P1) are arranged between a drive member (11) and a driven member (16). The first torque transmission path (P1) includes a first spring (SP1) for transmitting torque between the drive member (11) and the driven member (16). The second torque transmission path (P2) includes: first and second intermediate members (12, 14); a second spring (SP2) for transmitting torque between the drive member (11) and the first intermediate member (12); a third spring (SP3) for transmitting torque between the first intermediate member (12) and the second intermediate member (14); and a fourth spring (SP4) for transmitting torque between the second intermediate member (14) and the driven member (16).

Description

technical field [0001] The present disclosure relates to a vibration damping device including an input member and an output member, wherein power from an internal combustion engine is transmitted to the input member. Background technique [0002] Conventionally, a dual-channel damper used in connection with a torque converter is known as the above-mentioned damper (for example, refer to Patent Document 1). In this damping device, the vibration path from the engine and the lock-up clutch to the output hub is divided into two parallel vibration paths B and C, and the two vibration paths B and C respectively have a pair of springs and are arranged on the Separate middle flange between pair of springs. In addition, in order to make the resonance frequencies of the two vibration paths different, the turbine of the torque converter is coupled to the middle flange of the vibration path B, so that the natural frequency of the middle flange of the vibration path B is lower than the ...
