The invention relates to a torque transmission device comprising a torque converter, a pump impeller, a turbine wheel and optionally a stator. The inventive device also comprises a converter bypass coupling having a flange (19) which is connected to the housing (6) or the pump impeller (10) in a positively engaged manner. Said flange is arranged between the pump impeller (10) and the turbine wheel (9) and can be connected to the turbine wheel (9) in a frictionally engaged manner by means of a first coupling (27).

A centrifugal force pendulum having a pendulum mass pair and a pendulum flange, in which an arcuate cut-out with a cut-out contour is provided, wherein the pendulum masses of the pendulum mass pair are situated on both sides of the pendulum flange and are connected to each other by at least one spacer bolt which is guided through the cut-out, wherein the spacer bolt has a damping arrangement which includes a stabilizing element and an elastic damping element, wherein the damping element is designed to damp a striking of the spacer bolt on the cut-out contour of the cut-out, wherein the damping element and the stabilizing element of the damping arrangement are positioned relative to each other so that the damping element is able to strike the cut-out contour of the cut-out directly.

Centrifugal force pendulum

A torsional-vibration damper comprises three concentric ring elements being a hub ring, a flywheel ring and an elastic ring. The flywheel ring is mounted radially inside the hub ring and inside the elastic ring mounted between the hub ring and the flywheel ring. The operating frequency of the torsional-vibration damper is thereby dependent on anguular speed such that as the angular speed increases, the effective operating frequency of the tornsional-vibration damper is shifted higher by increased stiffening of the elastic link between the flywheel ring and the hub ring due to the centrifugal force.

Centrifugal pendulum device including pendulum masses arranged on axial sides of a pendulum mass support rotatable about an axis of rotation to form a pendulum mass pair. To form the mass pair, the masses are fastened to each other by means of a fastener passing through a cutout in the mass support. The mass pair is pivotable relative to the mass support due to a rolling element arranged to roll in a recess of the mass support and of the mass. In a section axially covering the recess of the mass support, the rolling element has a first outer diameter. In a section axially covering the recess of the pendulum mass, the rolling element has a second outer diameter. The rolling element further comprises a section axially located between the first and second diameters and has a third diameter, which is smaller than or equal to the first outer diameter.
