  • Patent number: 9683627
    Abstract: A filtering mechanism for torque fluctuations is interposed between a crankshaft of an internal combustion engine and a transmission. This mechanism comprises a rotating member to be damped, an oscillating inertial flywheel rotating around the axis of revolution, and pivot-mounted modules allowing angular deflection of the oscillating inertial flywheel with respect to the member to be damped. The modules each have at least one oscillating arm pivoting radially with respect to the member to be damped and a kinematic connecting member between the oscillating arm and the oscillating inertial flywheel. When the mechanism rotates centrifugal forces on the oscillating arm produce a counteracting torque that tends to return the oscillating inertial flywheel and the member to be damped toward the equilibrium position. The counteracting torque increases with the rotation speed of the filtering mechanism and with the amplitude of the angular deflection.

  • Publication number: 20170009844
    Abstract: A device for damping torsional oscillations comprises a support rotatable around an axis. At least one pendulum body is movable with respect to the support. At least one bearing member interacts with at least one raceway integral with the support and with at least one raceway integral with the pendulum body. The bearing member rolls along each raceway around an inactive raceway position. The first region is shaped to filter a first order value of the torsional oscillations by the pendulum body when the bearing member rolls along that first region. Two second regions are beyond an end of the first region. Each second region is shaped to filter a second order value of the torsional oscillations by the pendulum body when the bearing member rolls along one of those second regions. The second order value is strictly lower than the first order value.
