Definitions

  • the invention relates to a hinge for motor vehicles, in particular for tailgates, with a first joint part and a second joint part, which are pivotally mounted about an axis of rotation to each other.
  • a hinge which has a first hinge part and a second hinge part.
  • the two joint parts are pivotally mounted to each other by means of a pivot bearing insert unit.
  • the pivot bearing insertion unit comprises a first bearing shell fixedly connected to the first joint part and a second bearing shell fixedly connected to the second joint part.
  • On opposite sides of the two bearings are by means of sliding surfaces to each other and thus allow pivoting thereof about the axis of rotation.
  • Object of the present invention is to develop a hinge for motor vehicles such that on manufacturing technology favorable way a safe and long-term stable pivoting of a component is made possible.
  • the invention in conjunction with the preamble of claim 1, characterized in that the first hinge part is formed as a three-dimensional joint body having a bead-free outer contour having a plurality of hollow chambers extending perpendicular to the axis of rotation.
  • the particular advantage of the invention is that the design of a joint part as a three-dimensional joint body, which has a number of perpendicular to the axis of rotation hollow chambers, on the one hand a high mechanical stress-fulfilling and on the other hand a weight-saving hinge is created.
  • the hinge according to the invention can serve, for example, for pivoting a tailgate of a motor vehicle.
  • the basic idea of the invention is to give the joint body such a strength by designing hollow chambers that the outer contour of the joint body can be substantially free of beads. The outer contour of the joint body can thus be stylistically appealing without the joint body having to be provided with an additional plastic layer for cladding the joint body. As a result, the production cost can be reduced.
  • the visible in the mounting position of the hinge outer contour of the joint body forms a continuous surface, which has no erratic elevations or depressions.
  • the visible surface is straight or curved a gradually increasing or decreasing or constant radius.
  • the joint body has a closed outer surface (outer contour).
  • the hollow chambers of the first joint part in cross-section polygonal or honeycomb-shaped.
  • the hollow chambers are arranged distributed in at least one circular ring or at least one circular ring cutout about a central axis. Due to the polygonal configuration of the hollow chambers, a particularly high mechanical strength of the first joint part or of the hinge can be achieved.
  • a number of hollow chambers of the first joint part on opposite side walls which extend radially to a central axis.
  • the hollow chambers thus extend concentrically to the central axis.
  • a number of hollow chambers opposite a short wall and a long wall which extend substantially arcuately in the circumferential direction about the central axis, namely at a distance therefrom.
  • the hollow chambers are formed in cross section irregular to each other.
  • the extending between the hollow chambers continuous struts have a wall thickness which is within a predetermined range.
  • the hollow chambers are closed on the axis of rotation facing end, while they are formed open on the opposite end face.
  • the formation of the hollow chambers can be effected by means of a tool slide, wherein the hinge can be produced after inserting a first bearing shell and a second bearing shell in a mold in a single step.
  • the production cost can be reduced.
  • An inventive hinge 1 for motor vehicles can serve, for example, for pivoting a tailgate.
  • the hinge 1 it is also possible to pivot doors or other components used in the automotive sector or other industries.
  • the hinge 1 has a block-shaped first joint part 2 and a second joint part 3, which are mounted pivotably relative to each other about a rotation axis D.
  • the first joint part 2 designed as a three-dimensional joint body is firmly connected to a first hat-shaped bearing shell 5 at an extension section 17 thereof.
  • the second joint part 3 is fixedly connected to a second bearing shell 6, which - like the first bearing shell 5 - has on a mutually facing side a bearing surface, so that the first bearing shell 5 and the second bearing shell 6 slidably abut each other.
  • the two bearing shells 5, 6 are each hat-shaped and correspond to the shape as shown in the DE 100 33 487 C2 is known.
  • the first bearing shell 5 and the second bearing shell 6 each have a circumferential outer edge 7 which extends in the radial direction raised to an adjacent wall 8 of the first joint part 2 and a wall 9 of the second joint part 3. This ensures that after inserting the first bearing shell 5 and the second bearing shell 6 in a mold, the hinge 1 can be produced by die casting in a single step.
  • the outer edges 7 divide the mold space into two separate space parts, so that two different joint parts 2, 3 can be formed.
  • the first bearing shell 5 and the second bearing shell 6 may be formed, for example, as Blechhütchen.
  • the first joint part 2 and the second joint part 3 may be made of a same material, for example a light metal alloy, a plastic or any other material or metal alloy (Zink horrg tellmaschine).
  • the first bearing shell 5 and the second bearing shell 6 form a rotary bearing insertion unit.
  • the second housing part 3 may be attached to a tailgate, not shown, of the motor vehicle.
  • the second joint part 3 has two holes 10 for the introduction of fastening screws, not shown.
  • the first joint part 2 can be fastened to a body part of the vehicle.
  • the first joint part 2 has a central bore 12, through which a fastening screw 13 can be pushed through as a fastening element, which is in the assembly position in rotary engagement with an internal thread of the body part.
  • a head 14 of the fastening screw 13 bears against a second flat side 15 of the first joint part 2 that is essentially parallel to a first flat side 11 resting against the body part in the assembly position.
  • the first joint part 2 has a block-shaped or cube-shaped main section 16 and the extension section 17 adjoining the same at an angle, which is fixedly connected to the first bearing shell 5 as a massive axis of rotation section 26.
  • a plurality of hollow chambers 18 are provided, which are polygonal or honeycomb-shaped in cross-section.
