- the lifting device strikes the stop surface and prevents a further pendulum movement, so that neither a pendulum mass nor a pendulum roller strike metal against the pendulum flange.
- the stop means is arranged on a radial inside of the centrifugal force pendulum and is in another
- Embodiment of the invention part of a spacer.
- the spacer is preferably a plastic component prevents the pendulum mass from tarnishing on the pendulum flange.
- the centrifugal pendulum comprises two
- Pendulum masses which are arranged on both sides of the carrier disc, the

- the centrifugal force pendulum comprises an additional mass arranged between the pendulum masses, the spacer being arranged between the additional mass and the pendulum mass.
- the additional mass can consist of one sheet or several stacked sheets.
- the spacer is L-shaped and has an axially extending stop lug.
- a rubber element is preferably arranged on the stop lug, for example vulcanized.
- the stop lug encompasses the pendulum mass on its radial inside. This supports the stop lug on the
- a rubber coating is arranged on the stop lug.
- At least one spacer is arranged on both pendulum masses. There is preferably at least one spacer for each of the pendulum directions, each with a sling.

- Figure 4 shows a third embodiment of an inventive
- Centrifugal pendulum device as a schematic diagram in a sectional view.
- Figure 1 shows an embodiment of a centrifugal pendulum device 1 in a plan view as a comparative example for understanding the invention.
- Centrifugal pendulum device 1 is essentially rotationally symmetrical to an axis of rotation R. Here, a rotation about the circumferential direction
- Rotation axis R the direction parallel to the axial direction

- connection is made by a screw connection, for which purpose a large number of bores 3 for receiving screws are arranged distributed over the circumference of the centrifugal pendulum device 1.
- centrifugal pendulum device 1 Distributed over the circumference of the centrifugal pendulum device 1 are several, in the present exemplary embodiment four, centrifugal pendulum 4.
- Centrifugal pendulums 4 each include a first or engine-side pendulum mass 5 and a second or gear-side pendulum mass 6.
- the terms engine-side and gear-side are used here only for easier differentiation and easier understanding of the device and the arrangement of the parts of the device.
- the first pendulum mass 5 and the second pendulum mass 6 are on both sides of the carrier disk 2 arranged and firmly connected.
- the first pendulum mass 5 and the second pendulum mass 6 are firmly connected to one another by several, in the present exemplary embodiment three, rivet bolts 7.
- Both the first pendulum mass 5 and the second pendulum mass 6 have a plurality of bores which serve to receive the rivet bolts 7.
- Pendulum rollers 9 are accommodated in slots 8 in the carrier disk 2.
- Pendulum rollers 9 each comprise a cylindrical middle part which is provided with roller centering rims at both axial ends.
- the roller centering rims are used for the axially positive locking of the pendulum rollers 9 in the elongated holes 8.
- the roller ends of the pendulum rollers 9 projecting axially beyond the respective roller centering rims each protrude into elongated holes 11 in the pendulum masses 5 and 6.
