1. A centrifugal pendulum (1) in a torsional vibration damper of a drive train of a motor vehicle with:
a pendulum flange (2) rotatable about a first rotation axis (24) and including:
a first plurality of cutouts; andfirst and second cutouts separate from the first plurality of cutouts; first and second restrictedly displaceable pendulum masses distributed over a circumference, the first pendulum mass disposed on a first side of the pendulum flange and the second pendulum mass disposed on a second side of the pendulum mass, opposite the first side; third and fourth cutouts in the first pendulum mass; fifth and sixth cutouts in the second pendulum mass; a plurality of connectors, each connector:
passing through a respective cutout from the first plurality of cutouts and rigidly connected to the first and second pendulum masses; a first rolling element:
passing through the first cutout with respective first and second ends disposed within the third and fifth cutouts and including:
a second rotation axis passing through the respective first and second ends of the first rolling element;a first ring board:
extending from the first rolling element in a first direction orthogonal to the second rotation axis;located between the pendulum flange and the first pendulum mass in an second direction parallel to the second rotation axis; and,aligned with the first and third cutouts in the second direction;a second ring board:
extending from the first rolling element in the first direction;located between the pendulum flange and the second pendulum mass in the second direction; and,aligned with the first and fifth cutouts in the second direction; a first gap, in the second direction, located between the first ring board and the first pendulum mass; a second gap, in the second direction, between the second ring board and the second pendulum mass; and, a second rolling element passing through the second cutout with respective first and second ends disposed within the fourth and sixth cutouts, wherein:
the first and second rolling elements are displaceable with respect to the flange and the first and second pendulum masses;a line, in the second direction, passes through the first and second pendulum masses, the first and second gaps, and the pendulum flange;a first limit stop forms, with the first rolling element, a first chamber at least partially filled with hydraulic fluid;second and third limit stops for the third cutout form, with the first rolling element, second and third chambers at least partially filled with hydraulic fluid; and,the first, second, and third chambers are at least partially sealed by the first ring board. |
