Abstract

A centrifugal pendulum device having at least one flange and at least one centrifugal weight disposed displaceably on the flange. The centrifugal weight is guided displaceably on the flange by roller elements; the flange has openings with guide tracks situated radially outwardly, and the centrifugal weight has two side elements with a guide rail arranged therebetween and has guide tracks; the guide rail is inserted into an opening in the flange; the weight guide tracks are arranged radially inside the flange guide track such that they oppose each other in the radial direction at the same axial height, and roller elements are arranged radially therebetween; the flange having first and second openings with respective first and second guide tracks; the at least one centrifugal weight being inserted into one of the first or second openings depending on the choice of rotary vibration to be damped.

First claim

The invention claimed is:

1. A centrifugal pendulum device, comprising:
at least one flange;
at least one centrifugal weight disposed displaceably on the at least one flange, the at least one centrifugal weight being guided displaceably on the at least one flange by roller elements;
the flange having openings with guide tracks arranged radially on a radially outer side thereof;
the at least one centrifugal weight having two side elements with guide rails arranged therebetween with weight guide tracks, the guide rail of one said centrifugal weight being inserted into one of the openings of the flange, the weight guide tracks being arranged radially inside the guide tracks of the flange so that the guide tracks of the flange and the weight guide tracks are arranged to oppose each other at a same axial height in a radial direction and the roller elements are arranged therebetween in the radial direction;
the openings in the flange include at least one first opening configured for damping a first rotary vibration order and having first ones of the guide tracks, and at least one second opening configured for damping a second rotary vibration order and having second ones of the guide tracks; and
the guide rail of the at least one centrifugal weight is inserted into one of the first or the second opening that is assigned to a selected one of the first or second rotary vibration orders to be damped.

2. The centrifugal pendulum device according to claim 1 , wherein the flange has two of the first openings having the first guide tracks and two of the second openings having the second guide tracks, two of the centrifugal weights are provided which are inserted respectively into the two first openings or into the two second openings.

3. The centrifugal pendulum device according to claim 2 , wherein the two first openings are arranged to oppose each other and the two second openings are arranged to oppose each other, with the first openings and the second openings alternating.

4. The centrifugal pendulum device according to claim 1 , wherein a first one of the centrifugal weights is inserted into the first opening having the first guide tracks or a second one of the centrifugal weights is inserted into the second opening having the second guide tracks.

5. The centrifugal pendulum device according to claim 4 , wherein the first centrifugal weight is not equal to the second centrifugal weight.

6. The centrifugal pendulum device according to claim 4 , wherein the first centrifugal weight is equal to the second centrifugal weight.

7. The centrifugal pendulum device according to claim 1 , wherein the at least one first opening comprises two of the first openings and respective a first ones of the centrifugal weights are inserted into each of the first openings having the first guide tracks or the at least one second opening comprises two of the second openings and respective second ones of the centrifugal weights are inserted into each of the second openings having the second guide tracks.

8. The centrifugal pendulum device according to claim 7 , wherein the first centrifugal weight is not equal to the second centrifugal weight.

9. The centrifugal pendulum device according to claim 7 , wherein the first centrifugal weight is equal to the second centrifugal weight.

10. A family of centrifugal pendulum devices having first and second ones of the centrifugal pendulum devices according to claim 1 in the first centrifugal pendulum device the at least one centrifugal weight is inserted into the at least one first opening and in the second centrifugal pendulum device the at least one centrifugal weight is inserted into the at least one second opening.

11. The family of centrifugal pendulum devices according to claim 10 , wherein the at least one first opening in the first centrifugal pendulum device comprises two of the first openings, the at least one centrifugal weight of the first centrifugal pendulum device comprises two first centrifugal weights, each of which is inserted into one of the first openings and wherein the at least second opening in the second centrifugal pendulum device comprises two of the second openings, the at least one centrifugal weight of the second centrifugal pendulum device comprises two second centrifugal weights, each of which is inserted into one of the second openings.

12. A centrifugal pendulum device, comprising:
a flange;
a centrifugal weight disposed displaceably on the flange, the centrifugal weight being guided displaceably;
the flange having openings with guide tracks arranged radially on a radially outer side thereof;
the centrifugal weight having two side elements with guide rails arranged therebetween with weight guide tracks, the guide rail of the centrifugal weight being inserted into one of the openings of the flange, the weight guide tracks being arranged radially inside the guide tracks of the flange so that the guide tracks of the flange and the weight guide tracks are arranged to oppose each other at a same axial height in a radial direction;
the openings in the flange include two first openings configured for damping a first rotary vibration order and having first ones of the guide tracks, and two second opening configured for damping a second rotary vibration order and having second ones of the guide tracks; and
wherein there are two of the centrifugal weights, the guide rail of each being inserted into one of the first openings or the guide rail of each being inserted into one of the second openings that is assigned to a selected one of the first or second rotary vibration orders to be damped.

13. The centrifugal pendulum device according to claim 12 , further comprising roller elements arranged between the weight guide tracks and the guide tracks of the flange in the radial direction.

14. The centrifugal pendulum device according to claim 12 , wherein a weight of one of the centrifugal weights is not equal to a weight of the other centrifugal weight.

15. The centrifugal pendulum device according to claim 12 , wherein a weight of one of the centrifugal weights is equal to a weight of the other centrifugal weight.

16. The centrifugal pendulum device according to claim 12 , wherein the two first openings are arranged to oppose each other and the two second openings are arranged to oppose each other, with the first openings and the second openings alternating.
