A centrifugal pendulum (10) is provided for damping rotational irregularities introduced via a drive shaft of an motor vehicle, and comprises a support flange (12) which is rotatable about an axis of rotation for indirect or direct attachment to the drive shaft, a pendulum mass (14) which can swing relative to the support flange (12) for producing a restoring torque directed against the rotational irregularity, and a roller (20) guided in a track (16) on the support flange (12) and in a pendulum path (18) of the pendulum mass (14). The roller (20) has a radially outwardly protruding spacing edge (22) for spacing the pendulum mass (14) from the support flange (12), wherein the spacing edge (22) between the transitions of the substantially axially directed flank faces (24) of the spacing edge (22) and the radially externally directed rolling surfaces (28) of the roller (20), without taking account of transitional radii (26) in the new state, has an edge width X. The pendulum mass (14) in the new state has a mean spacing Y from the support flange (12) and wherein 0.60 ≤ X/Y ≤ 1.00, in particular 0.70 ≤ X/Y≤1.00, preferably 0.80 ≤ X/Y ≤ 0.98 and particularly preferably 0.90 ≤ X/Y ≤ 0.95 applies. Very smooth running and low wear of the pendulum mass (14) can be achieved by the selected ratio of the edge width X to the mean spacingYof the pendulum mass (14), by means of which a wear-related imbalance of the centrifugal pendulum (10) occurring over the service life can be avoided, such that a long-lasting damping capacity of the centrifugal pendulum (10) is made possible. |
