Abstract

Chassis part of a vehicle, with a magnet (2) and at least one electric coil (10), which interacts with the magnetic field generated by the magnet (2), wherein the magnet (2) and the coil (10) are mobile in relation to one another. The chassis part (13) can perform vibrations with at least one natural frequency, wherein the magnet (2) is fastened to a spring (8) and is mobile relative to the coil (10), and wherein the natural frequency of the oscillator (14) having the magnet (2) and the spring (8) is tuned to the natural frequency of the chassis part (13).

Claims

1. A chassis part of a vehicle, the chassis part comprising:

a spring;

a magnet; and

at least one electric coil, which interacts with the magnetic field generated by the magnet, wherein the magnet and the coil are mobile in relation to one another, wherein the chassis part can perform vibrations at least one natural frequency, the magnet is fastened to said spring and is mobile relative to the coil, and the natural frequency of the oscillator having the magnet and the coil is tuned to the natural frequency of the chassis part.

2. A chassis part in accordance with claim 1, wherein the magnet is guided linearly movably in a sleeve made of a nonmagnetic material.

3. A chassis part in accordance with claim 1, wherein the magnet is fastened in a sliding element made of a nonmagnetic material.

4. A chassis part in accordance with claim 1, wherein the spring is a coil spring.

5. A chassis part in accordance with claim 1, wherein the magnet is arranged in the spring.

6. A chassis part in accordance with claim 1, wherein a second electric coil is provided and the magnet is arranged between the two electric coils.

7. A chassis part in accordance with claim 6, wherein the two electric coils have a core each made of a magnetic material, wherein the two cores are connected to one another via a housing made of a magnetic material.

8. A chassis part in accordance with claim 7, wherein the magnet, the spring and the two coils are arranged in the housing.
