Title:
TORQUE DAMPER DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/126245
Kind Code:
A1
Abstract:
Provided is a torque damper device capable of significantly reduced rigidity, and which can achieve sufficient vibration absorption properties by increasing the torque variation attenuation factor. This torque damper device (10) is provided with a clutch piston (11) to which the engine torque is inputted, and a damper spring capable of absorbing variations in the torque inputted from the clutch piston (11), and drive force of the engine can be transmitted via the clutch piston and a damper spring to this torque damper device (10). The damper spring is made up of multiple coil springs (S1-S3) arranged along the circumferential direction of the clutch piston (11), and has a first separate member (14) and a second separate member (15) which are interposed between the damper springs (S1-S3) and which can rotate independently of one another when engine torque is transmitted.
