Definitions

  • the invention relates to a hinge, in particular a door hinge for motor vehicles, having a hinge pin having a first hinge part and having a cooperating with the bearing pin bearing bush second hinge part, wherein at least one of the hinge parts is at least substantially made of plastic.
  • the invention relates to a hinge part for a hinge, in particular as described above, wherein the hinge part is at least substantially made of plastic and carries a bearing pin or a bearing bush.
  • the invention relates to a method for producing a hinge part of a hinge, in particular as described above, wherein the hinge part is at least substantially made of a plastic material or plastic and provided with a bearing pin or with a bearing bush.
  • Hinges and especially door hinges are widely used in automotive engineering. In addition to the actual task of providing a joint, hinges in motor vehicle construction must meet even further requirements, some of which are also subject to legal provisions. For example, door hinges must be designed such that they can transmit high forces in a crash, to maintain the security cell, and can be solved or separated after the crash, to allow removal of the door to release occupants.
  • the publication DE 103 30 162 A1 discloses, for example, a hinge which has two hinge parts, or also referred to as a trade, of which a first carries a bearing pin and a second one cooperating with the bearing pin or the hinge-forming bearing bush. It is proposed to manufacture one of the hinge parts made of a fiber-reinforced plastic.
  • the invention has for its object to provide a hinge, a hinge part and a method for producing a hinge part such that the hinge part or the hinge despite high weight has a high load capacity.
  • the object underlying the invention is achieved in each case by a hinge with the features of claim 1, by a hinge part with the features of claim 9 and by a method for producing a hinge with the features of claim 10.
  • the hinge according to the invention with the features of claim 1 has the advantage that it can be made smaller and lighter overall than a well-known from the prior art hinge to accommodate the same forces safely.
  • the carbon fiber reinforced support structure is particularly light and at the same time heavy duty, resulting in the above advantages.
  • the load capacity of the hinge thus results largely from the support structure, whereby the requirements for the remaining plastic are lower.
  • both hinge parts on a carbon fiber reinforced support structure so that the hinge parts of the hinge acting together are gleichgeartet and so far both have the advantages mentioned above. Overall, this creates a hinge that is lightweight on the one hand and very efficient on the other. Since the shape of the hinge does not change or does not fundamentally change compared to a conventional hinge, the hinge according to the invention continues to meet the requirements for releasability or separability of the hinge parts.
  • the respective support structure is formed as a hollow profile.
  • the support structure forms a closed support wall, which is particularly resilient.
  • the height of the hollow profile corresponds to the height of the base part.

  • the plastic is preferably fiber-reinforced, in particular glass-fiber reinforced. This increases the strength of the base.
  • the carbon fiber reinforced support structure is preferably made as a plastic-based fiber composite. The fact that the support structure and base have a plastic content, these can be firmly connected to each other in a simple manner. In particular, when the temperature of the injected plastic in the hollow profile exceeds the melting point of the plastic of the support structure, a material or cohesive connection of the two elements takes place together, which causes a high load capacity of the respective hinge part.
  • the bearing pin and / or the bushing have at least partially in their area surrounding the plastic a corrugation for preventing rotation on their respective outer shell wall.
  • the corrugation expediently extends in axial extension of the bearing pin or the bearing bush, whereby a positive rotation in the circumferential direction is offered in a simple manner.
  • the corrugation extends over the entire area surrounded by plastic portion of the bearing bush or the bearing pin.
  • the bearing pin and / or the bearing bush preferably each have at least one radial projection, which forms at least one contact shoulder in the axial direction.
  • the bearing pin and / or bearing bush in an exposed portion of a receptacle for a locking or locking ring, which can be retrofitted or removed.

For example, if the bearing pin unilaterally with the radial projection and otherwise provided with the receptacle for the locking ring, so can the bearing pin with the receiving end having introduced into the corresponding opening of the hinge part until the radial projection comes into abutting contact with the hinge part. The then expediently exposed on the other side of the hinge portion recording is then provided with the locking ring, whereby the bearing pin is held in a simple manner total captive on the hinge part.
  • the first and / or the second hinge part have at least one threaded bush, which is at least substantially held by the plastic.
  • the threaded bushing has, as the name implies, a thread, and is preferably used to attach the respective hinge part to the body or a door of the motor vehicle.
  • the threaded bushing preferably has an internal thread and is arranged in a receptacle of the base part.
  • the threaded bushing is cup-shaped, so that it can be encapsulated with the plastic mass of the base without plastic enters the threaded area.
  • the support structure has an opening in the region of the threaded bush, so that it is accessible from the outside through the support structure.
  • the threaded bushing on its outer shell side cooperating with the plastic corrugations to prevent rotation, so when tightening a co-operating with the threaded bush screw for attaching the hinge part high tightening torques can be achieved without the threaded bush dissolves.
  • the hinge part according to the invention with the features of claim 9 is characterized in that it has a carbon fiber reinforced support structure. This results in the advantages already mentioned above, in particular with regard to the load capacity and the low weight. Advantageous developments of the hinge part result from the above features and claims.
  • the inventive method for producing a hinge part with the features of claim 10 is characterized in that initially a carbon fiber-reinforced Provided support structure and then provided with the plastic compound or with the plastic.
  • the plastic compound is applied to the support structure by an injection process or introduced into the support structure.
  • the support structure is provided as a hollow profile and the plastic material injected into the hollow profile.
  • the support structure is made of a carbon fiber reinforced strand hollow profile, wherein the extruded profile preferably already has the contour of the support structure or where a separated from the strand section brought by a subsequent processing step in the desired structure or shape becomes.
  • the front sides of the hollow profile are subsequently processed for example by punching, drilling or cutting operations to obtain the desired hinge part shape.
  • the bearing pin or the bearing bush is encapsulated by the plastic, as described above. Overall, a hinge part is thereby produced in a simple manner, which is light and resilient.
