Door hinge for a motor vehicle
View Patent ↗A door hinge for a motor vehicle comprises a column console that can be arranged on a column of a door frame, a door console that can be attached to a motor vehicle door assigned to the door frame, wherein the door console and the column console are pin-jointed together via a hinge pin and the door console or column console is formed from two releasably connected partial units, which rest against each other at assigned contact areas. In order to provide a separable motor vehicle door hinge with an at least two-piece door or column console, which enables a dimensionally accurate restoration of an original installation position even after a separation, it is provided that the contact surfaces on the door and/or column console are formed by delineated partial surfaces.
1. A door hinge for use on a motor vehicle, said hinge comprising:
a column console arranged on a column of a door frame of said motor vehicle;
a door console attached to a motor vehicle passenger door assigned to the door frame;
the door console and the column console being pin-jointed together via a hinge pin and at least one of the door console and the column console being formed from two releasably connected partial units, which rest against each other at assigned contact areas and which cannot move relative to each other when connected; and
contact surfaces on at least one of the door console and column console being formed by spaced partial surfaces.
2. The motor vehicle door hinge according to claim 1 , wherein the partial surfaces have at least one of a high dimensional accuracy and surface quality.
3. The motor vehicle door hinge according to claim 1 , wherein said partial units include a first partial unit surrounding a second partial unit in a U-shaped manner.
4. The motor vehicle door hinge according to claim 1 , wherein the first partial unit has a first main partial surface and two first auxiliary partial surfaces arranged tilted with respect to the first main partial surface.
5. The motor vehicle door hinge according to claim 4 , wherein the second partial unit has a second main partial surface assigned to the first main partial surface of the first partial unit and two second auxiliary partial surfaces assigned to the auxiliary partial surfaces of the first partial unit.
6. The motor vehicle door hinge according to claim 5 , wherein the second main partial surface and the second auxiliary partial surfaces are formed from delineated areas.
7. The motor vehicle door hinge according to claim 5 , wherein the second main partial surface is made up of three areas and wherein a surface of a middle one of said areas is set back with respect to surfaces of the other areas and has a threaded bore hole for receiving a fastening screw for arrangement of the first partial unit on the second partial unit.
8. The motor vehicle door hinge according to claim 7 , wherein the surface of the middle area is set back with respect to the surfaces of the other areas of the second main partial surface such that the first partial unit is deformed in an elastic area in a state connected with the second partial unit.
9. The motor vehicle door hinge according to claim 4 , wherein the first partial unit is formed from a bent sheet metal part and the second partial unit is formed from a forged part.
10. The motor vehicle door hinge according to claim 1 , wherein a part of the column console that can be arranged on-board of a vehicle is made up of a forged part.
11. The motor vehicle door hinge according to claim 4 , wherein the first and second partial units are connected together by a fastening screw designed as a fitting screw and wherein the first partial unit has an opening for receiving the fitting screw.
12. The motor vehicle door hinge according to claim 11 , wherein the opening is formed as a long hole aligned in a transverse direction of the first partial unit.
