Abstract

A balancing weight for balancing a wheel of a vehicle has a body of non-ferromagnetic material providing a major portion of the balancing weight's mass and a ferromagnetic inlay for holding the balancing weight by magnetic force. The ferromagnetic inlay provides a minor portion of the balancing weight's mass. A weight applicator has a magnet for interacting with the ferromagnetic inlay of the balancing weight and holding the balancing weight.

Claims (36)

1. Balancing weight comprising:

a body of non-ferromagnetic material having a first side and a second side; and

a ferromagnetic inlay disposed in the body and configured to couple the balancing weight to a handling device by magnetic force,

wherein, in a cross-sectional plane, the first side has a first dimension that is greater than a second dimension of the second side; and

wherein the ferromagnetic inlay provides at least one contact surface located on at least the second side of the body of the balancing weight.

2. Balancing weight according to claim 1 , wherein the ferromagnetic inlay comprises a cylindrical-shaped rod.

3. Balancing weight according to claim 1 , wherein the ferromagnetic inlay provides one contact surface at one side of the balancing weight body.

4. Balancing weight according to claim 1 , wherein a surface of the ferromagnetic inlay is parallel to an attachment side of the balancing weight body.

5. Balancing weight according to claim 1 , wherein the body comprises a majority of the mass of the balancing weight, and the ferromagnetic inlay comprises a minority of the mass of the balancing weight.

6. Balancing weight according to claim 1 , further comprising an adhesive tape attached to the body.

7. Balancing weight according to claim 1 , further comprising:

a metal clip configured to couple the balancing weight to a rim of a wheel,

wherein the ferromagnetic inlay is physically separated from the clip.

8. Balancing weight according to claim 1 , wherein the ferromagnetic inlay is covered by a cover material.

9. Balancing weight according to claim 1 , wherein the ferromagnetic inlay is disposed within a cutout in the body of the balancing weight.

10. Balancing weight according to claim 9 , wherein the cutout is sealed by a sealing material.

11. Weight applicator for applying a balancing weight according to claim 1 , comprising:

at least one magnet configured to interact with the ferromagnetic inlay of the balancing weight to couple the balancing weight to the weight applicator by magnetic force.

12. Weight applicator according to claim 11 , wherein the at least one magnet comprises at least one magnet selected from the group consisting of permanent magnets and electrical magnets.

13. Method for handling balancing weights according to claim 1 , the method comprising:

moving an applicator head toward a balancing weight,

coupling the balancing weight to the applicator head by magnetic force,

moving the applicator head together with the balancing weight to a rim of a wheel, and

releasing the balancing weight from the applicator head.

14. Method for handling balancing weights according to claim 13 ,

the method further comprising:

enabling an electrical magnet within the applicator head after the applicator head has been moved toward the balancing weight and

disabling the electrical magnet within the applicator head after the balancing weight has been moved to the rim.

15. Balancing weight comprising:

a single-piece body with a cuboid shape having rounded corners and edges, the single-piece body comprising a non-ferromagnetic material; and

a ferromagnetic inlay configured to couple the balancing weight to a handling device by magnetic force;

wherein the ferromagnetic inlay is completely embedded in the non-ferromagnetic material of the single-piece body.

16. Balancing weight according to claim 15 , wherein the ferromagnetic inlay comprises a cylindrical-shaped rod.

17. Balancing weight according to claim 15 , wherein the single-piece body comprises a majority of a mass of the balancing weight, and the ferromagnetic inlay comprises a minority of the mass of the balancing weight.

18. Balancing weight according to claim 15 , wherein a surface of the ferromagnetic inlay is parallel to an attachment side of the single-piece body of the balancing weight.

19. Balancing weight according to claim 15 , further comprising an adhesive tape attached to the single-piece body.
