Torsional vibration damper for hydrokinetic torque coupling device with inner and outer elastic damping members connected in series

摘要

A hydrokinetic torque coupling device comprises a casing rotatable about a rotation axis, a torque converter including an impeller wheel and a turbine wheel disposed in the casing coaxially with the rotation axis, a turbine hub disposed in the casing coaxially with the rotation axis and fixed to the turbine wheel, and a torsional vibration damper. The torsional vibration damper comprises a driven member fixed to the turbine hub, a drive member rotatable relative to the driven member about the rotation axis, and a plurality of circumferentially acting outer and inner elastic damping members. The drive member and the driven member are operatively connected to both the radially outer and inner elastic damping members. The radially outer and inner elastic damping members are arranged in series.
