Embodiment Construction
[0020] Figures 1 to 3 A schematic illustration of a centrifugal pendulum device 1 is shown in each case in order to clarify the concept of the invention and an exemplary embodiment of the centrifugal pendulum device 1 according to the invention.
[0021] Figures 1 to 3 A centrifugal pendulum device 1 is shown, which has at least one flange element 3 which is rotatable about an axis of rotation 2 and which is arranged on the drive side. The at least one flange element 3 can be designed as one flange element 3 or as two flange elements 3 arranged in parallel. The at least one flange element is arranged on the drive side, which means that the flange element can be driven, for example, by a drive train.
[0022] The centrifugal pendulum device 1 is shown with a flange element 3 designed as a carrier element. Here, the variant in which the pendulum mass 4 is arranged on the flange element 3 on both sides of said flange element 3 is fully known, and also a centrifugal pendulum ...

The invention relates to a centrifugal force pendulum device (1) having at least one flange element (3) which can be rotated about a rotational axis, is arranged on the drive side, and on which pendulum masses (4) are arranged as flyweights in a manner which is articulated such that they can be moved, wherein the pendulum masses (4) are arranged distributed over the circumference on the at least one flange element (3) and are mounted on the at least one flange element (3) by means of pendulum bearings (5), wherein the pendulum masses (4) can swing with respect to the at least one flange element (3) in the centrifugal force field of the flange element (3) about a zero position with a predefined swing angle (a) by means of the pendulum bearings (5) which are formed from roller elements (7) which roll in each case on guide tracks (6) of the at least one flange element (3) and the pendulum masses (4), and are suspended such that they can be rotated partially about their centroid (S) during a pendulum movement, and wherein the pendulum and rotational movement of the pendulum masses (4) is predefined by way of the configuration of the guide tracks (6) and the coupling element (10), wherein the pendulum masses (4) are coupled to one another by way of a coupling element (10), wherein the coupling element (10) acts on the respective pendulum mass (4) at an isoradial point (11) which remains at the same radial height during a pendulum and rotational movement of the pendulum masses (4), wherein the respective spacing of the isoradial points (11) of the respective pendulum masses (4) also remains constant relative to one another.
Description
technical field [0001] The invention relates to a centrifugal pendulum device, in particular for a drive train of a motor vehicle. Background technique [0002] The centrifugal pendulum device usually has at least one flange element which is arranged on the drive side and on which the pendulum mass is arranged in an articulated displaceable manner as a centrifugal weight. Here, variants are known in which the pendulum mass is arranged on the flange element on both sides of said flange element, as well as centrifugal pendulum devices provided with two parallel arranged flange elements, wherein the pendulum A mass is arranged between said flange elements. In this case, the respective pendulum mass is displaceably guided via at least one guide rail in the flange element and in the pendulum mass and by means of at least one rolling element, wherein the rolling element fits into the in the guide rail. [0003] In principle, centrifugal pendulum devices are known in which eithe...
