Abstract

A mass damper system with a damper mass support receives a damper mass. A guide track and damper mass are in operative connection with one another by a coupling element movable in the guide track between a central position in which the coupling element is free from deflection in circumferential direction of the guide tracks and a deflection position out of the central position. The guide tracks and the coupling element are configured for an order that depends on the number of cylinders of the respective exciting drive. The guide tracks are tailored with respect to their geometric configuration for excitations of a virtual order between a first order associated with excitations of a drive with a first number of cylinders and a second order with which are associated with excitations of a drive with a second number of cylinders.

First claim

1. A mass damper system kit that damps excitations for a plurality of orders, comprising:
at least one damper mass having a damper mass guide track;
a damper mass support having at least one support guide track and configured to receive the at least one damper mass;
a plurality of coupling elements each configured to operatively connect the damper mass support and the at least one damper mass so that each coupling element is movable in the at least one support guide track and in the damper mass guide track between a central position in which each coupling element is free from deflection in circumferential direction of the at least one support guide track and the damper mass guide track and a deflection position in which a deflection has taken place in circumferential direction out of the central position,
wherein a composite comprising the at least one support guide track, the damper mass guide track, and a respective coupling element, the respective coupling element is configured for an order depending on a number of cylinders of a respective exciting drive,
wherein the at least one support guide track and the damper mass guide track are tailored with respect to their geometric configuration for excitations of a virtual order between a first order with which are associated excitations of a first drive with a first number of cylinders and a second order with which are associated excitations of a second drive with a second number of cylinders,
wherein a diameter of each coupling element is dimensioned based on the first order or the second order such that the diameter of the rolling elements is greater in the first drive with a larger number of cylinders than the second drive with a smaller number of cylinders,
wherein the first drive generates excitations of a higher order than the second drive with second number of cylinders,
wherein the at least one support guide track and the damper mass guide track are configured with respect to their geometric arrangement in accordance with the virtual order that lies in a middle between the first order and the second order to damp excitations for the first order and the second order.

2. The mass damper system kit according to claim 1 , wherein each of the coupling elements is a substantially cylindrical rolling element.

3. The mass damper system kit according to claim 1 , wherein the deflection that has taken place in circumferential direction out of the central position is constant for different diameters of the at least one coupling element.

4. The mass damper system kit according to claim 1 , wherein the constant deflection angle for the different diameters of the at least one coupling element is 55°.
