Title: HYDROKINETIC TORQUE COUPLING DEVICE WITH TORSIONAL VIBRATION DAMPER IN COMBINATION WITH TWO VIBRATION ABSORBERS
Abstract:
A hydrokinetic torque coupling device for coupling together driving and driven shafts, comprises a casing, impeller and turbine wheels, a torsional vibration damper, a turbine hub non-rotatably connected to the turbine wheel, and first and second vibration absorbers. Each of the first and second vibration absorbers is one of a dynamic absorber and a pendulum oscillator. The turbine hub is non-rotatably coupled to a driven member of the torsional vibration damper. The first vibration absorber is mounted to the turbine hub and the second vibration absorber is mounted to one of the turbine hub and the casing. The first vibration absorber and the second vibration absorber are tuned to address different orders of vibrations. The dynamic absorber includes an inertial member and a connecting plate coupled to the inertial member. The pendulum oscillator includes a support member and flyweights configured to oscillate relative to the support member.
