Hinge
A hinge to pivotably connect a motor vehicle door to a body of the motor vehicle. The hinge includes a bolt, a first hinge half rotationally connected to a bolt, a second hinge half, a bushing, composed of an electrically insulating material, arranged on the second hinge half to rotationally connect the second hinge half to the bolt, and an electrically conductive component arranged between the bolt and the second hinge half to bridge the bushing and facilitate electrical contact between the bolt and the second hinge half.
1. A hinge to pivotably connect a motor vehicle door to a body of the motor vehicle, the hinge comprising:
a bolt;
a first hinge half rotationally connected to a bolt;
a second hinge half;
a bushing, composed of an electrically insulating material, arranged on the second hinge half to rotationally connect the second hinge half to the bolt; and
an electrically conductive component, comprising a plastic having a high proportion of carbon or an elastomer having a high carbon proportion, arranged between the bolt and the second hinge half to bridge the bushing and facilitate electrical contact between the bolt and the second hinge half.
2. The hinge of claim 1 , wherein the bushing comprises a first bushing section and a second bushing section, and the electrically conductive component is positioned between the first bushing section and the second bushing section.
3. The hinge of claim 1 , wherein the electrically conductive component is axially positioned between the axial ends of the bushing.
4. The hinge of claim 1 , wherein the electrically conductive component is axially positioned at a middle of the length of the bushing.
5. The hinge of claim 1 , wherein the bushing is rotationally connected to the second hinge half.
6. The hinge of claim 1 , wherein the electrically conductive component comprises an O-ring.
7. The hinge of claim 1 , wherein the hinge comprises a cathodic dip-coating.
8. A motor vehicle, comprising:
a motor vehicle body;
a motor vehicle door; and
a hinge to pivotably connect the motor vehicle door to the motor vehicle body, the hinge including:
a bolt;
a first hinge half rotationally connected to a bolt;
a second hinge half;
a bushing, composed of an electrically insulating material, arranged on the second hinge half to rotationally connect the second hinge half to the bolt; and
an electrically conductive component, comprising a plastic having a high proportion of carbon or an elastomer having a high carbon proportion, arranged between the bolt and the second hinge half to bridge the bushing and facilitate electrical contact between the bolt and the second hinge half.
9. The motor vehicle of claim 8 , wherein the bushing comprises a first bushing section and a second bushing section, and the electrically conductive component is positioned between the first bushing section and the second bushing section.
10. The motor vehicle of claim 8 , wherein the electrically conductive component is axially positioned between the axial ends of the bushing.
11. The motor vehicle of claim 8 , wherein the electrically conductive component is axially positioned at a middle of the length of the bushing.
12. The motor vehicle of claim 8 , wherein the bushing is rotationally connected to the second hinge half.
13. The motor vehicle of claim 8 , wherein the electrically conductive component comprises an O-ring.
14. The motor vehicle of claim 8 , wherein the hinge comprises a cathodic dip-coating.
15. A method for producing a hinge to pivotably connect a motor vehicle door to a body of the motor vehicle, the method comprising:
rotationally connecting a first hinge half to a bolt;
rotationally connecting a second hinge half to the bolt via a bushing composed of an electrically insulating material;
positioning an electrically conductive component, comprising a plastic having a high proportion of carbon or an elastomer having a high carbon proportion, between the bolt and the second hinge half to bridge the bushing such that electrical contact occurs between the bolt and the second hinge half; and
cathodically dip-coating the hinge.
16. The method of claim 15 , wherein the bushing comprises a first bushing section and a second bushing section, and positioning the electrically conductive component comprises positioning the electrically conductive component between the first bushing section and the second bushing section.
