Embodiment Construction

[0019] figure 1 A side view of a centrifugal pendulum device 10 in a particular embodiment of the invention is shown. The centrifugal pendulum device 10 comprises a pendulum mass carrier 12 rotatable about an axis of rotation 100 , which has a spring window 14 arranged in the radially inner region for receiving an energy storage element not shown here. , such as coil springs. These energy accumulator elements are operatively connected to the pendulum mass carrier 12 and the further damper components of the torsional vibration damper, not shown here, in order to realize that under the action of these energy accumulator elements The pendulum mass carrier 12 is twisted.

[0020] Radially inside the spring window 14 , the output hub 16 is fastened, in particular riveted, to the pendulum mass carrier 12 , wherein the output hub 16 can be connected in a rotationally fixed manner to the transmission input shaft via a toothing 18 .

[0021] Radially on the outside, four pendulum ma...

Abstract

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.

Description

technical field [0001] The invention relates to a centrifugal pendulum device having the features according to the preamble of claim 1 . Background technique [0002] A torsional vibration damper arranged in a drive train of a motor vehicle is known from DE 10 2006 028 556 A1. The torsional vibration damper enables the transmission of torque generated by the drive side, for example by the internal combustion engine, to the output side, for example the gearbox, and can additionally act on the damping of torsional vibrations, such as may be induced by the internal combustion engine. For this purpose, the torsional vibration damper has a damper input part and a damper output part which can be twisted to a limited extent relative to the damper input part by the action of at least one energy storage element. [0003] In addition, torsional vibration dampers include centrifugal pendulum devices to further dampen and / or eliminate torsional vibrations in the drive train. Here, the...
