Embodiment Construction

[0034] figure 1 A first exemplary embodiment of a centrifugal pendulum device 2 is shown. Corresponding arrows in the drawings show mutually opposite axial directions 4, 6, mutually opposite radial directions 8, 10, and mutually opposite circumferential directions 12, 14, wherein the centrifugal pendulum device 2 can rotate about a central axis of rotation 16 for rotation, the central axis of rotation extends axially 4,6. The axial directions 4 , 6 are also referred to below as the first axial direction 4 and the second axial direction 6 .

[0035] The centrifugal pendulum device 2 has a pendulum bracket 18 . The pendulum carrier 18 is essentially disk-shaped or plate-shaped, in the exemplary embodiment shown it is ring-shaped, wherein the pendulum carrier 18 essentially extends along the plane in which one of the radial directions 8 , 10 lies. The pendulum carrier 18 is fixedly connected radially inwardly 10 to components in the torque transmission path of the drive train,...

Abstract

The invention relates to a centrifugal pendulum device (2) with a pendulum mass carrier (18), at least one pendulum mass counter weight (20), a pendulum mass counter weight section (22) arranged laterally of the pendulum mass carrier (18), and at least one rolling element (32) which extends in guide grooves (36, 40) in the pendulum mass carrier (18) and the pendulum mass counter weight section (22) such that the pendulum mass counter weight (20) is movable relative to the pendulum mass carrier (18), wherein, at least one support device (46) formed separately from the rolling element (32) is provided which is supportable or supported on the pendulum mass carrier (18) in a first axial direction (4). The support device (46) can be supportable or supported on the unrolling element (32) in a second axial direction (6) opposite to the first axial direction (4). Moreover, the invention relates to a torsional vibration damper with such a centrifugal pendulum device (2).

Description

technical field [0001] The invention relates to a centrifugal pendulum device, which has a pendulum bracket, at least one pendulum counterweight, a pendulum counterweight section arranged on the side of the pendulum bracket and at least one rolling element, the rolling element on the pendulum bracket Extending in guide slots in the pendulum frame and pendulum counterweight section and enabling the pendulum counterweight to move relative to the pendulum carriage, for this purpose at least one support device formed separately from the rolling elements is provided along the The first axial support is or is supported on the pendulum carriage. Background technique [0002] Various centrifugal pendulum devices are known in practice, which have a pendulum carrier and at least one pendulum counterweight arranged on the pendulum carrier. The pendulum weight has at least one pendulum weight section arranged on the side of the pendulum bracket, for example, the pendulum weight has two...
