Abstract

The invention relates to a vibration elimination system, comprising a shielding plate (2) for a motor component, at least one vibration elimination element (10) that is fastened to the shielding plate (2), wherein each vibration damping element (10) comprises a spring-mass system that is capable of vibration, the spring force and mass of which are dimensioned such that said spring-mass system is matched to a predetermined vibration frequency of the shielding plate (2).

Claims

1. A vibration elimination system, comprising

a heat shielding plate configured to protect a motor component from heat,

at least one vibration elimination element, which is

fastened to the heat shielding plate,

wherein each vibration elimination element comprises a spring-mass system that is capable of vibration, the spring force and mass of which are dimensioned such that said spring-mass system is matched to a predetermined vibration frequency of the heat shielding plate;

wherein the vibration elimination element comprises a metallic oscillation mass which is mounted in a manner where it is able to oscillate independently of the motor component and of the heat shielding plate, and

wherein the oscillation mass is mounted in a manner capable of vibration in an elastic casing which provides the spring force of the spring-mass system, and wherein the elastic casing is made of an elastomer and is fixedly mounted on the shielding plate, or

wherein the oscillation mass is mounted in a manner capable of vibration between two elastic elements, which provide the spring force of the spring-mass system, and wherein the elastic elements are made of an elastomer and are fixedly mounted on the heat shielding plate.

2. The vibration elimination system according to claim 1, wherein at least one vibration elimination element is fastened in a region of maximum vibration deflection of the shielding plate.

3. The vibration elimination system according to claim 1, wherein a plurality of vibration elimination elements are fastened at a predetermined distance around a region of maximum vibration deflection of the shielding plate.

4. The vibration elimination system according to claim 1, wherein at least two vibration elimination elements are mounted on the shielding plate, which are matched to different vibration frequencies.

5. The vibration elimination system according to claim 1, wherein at least one vibration elimination element is matched such that it shifts an initial vibration frequency of the shielding plate into a predetermined frequency range.

6. The vibration elimination system according to claim 1, wherein at least one vibration elimination element is matched such that it damps a predetermined vibration frequency of the shielding plate.

7. The vibration elimination system according to claim 1, wherein the spring-mass system is surrounded at least partially by a fixed casing.

8. The vibration elimination system according to claim 1, wherein during operation the oscillation mass is capable of vibration parallel to the deflection direction of the region of the shielding plate, in which the vibration elimination element is mounted.
