DAMPER DEVICE FOR VEHICLE

摘要

In a positive torsion angle region in which a torque is transmitted from an engine (24) side, a small hysteresis torque (HI) is generated at all times. Therefore, torsional vibrations of a small amplitude occurring during idle operation can be effectively attenuated by the small hysteresis torque (HI), without switching to a large hysteresis torque (H2), for example, during idle operation of the engine (24). As a result, the driver can be prevented from feeling uncomfortable due to switching to a large hysteresis torque during idle operation, and drivability can therefore be improved.
