Definitions

  • the invention relates to a motor vehicle door hinge, consisting of two hinge halves pivotably connected to one another by means of a hinge pin, in particular hinge wings, made of metal, the first hinge half being formed by a molded part with a hinge pin molded in one piece and in the same shape and material, and the overall height of the hinge pin is less than the total height of the hinge leaf, but the axial length of the hinge pin is the same size or greater than the axial length of the hinge eye of the second hinge half.
  • Motor vehicle door hinges are mass-produced parts, however, in contrast to door hinges for building or furniture doors, they are exposed to considerably greater loads and in particular also to environmental influences such as large temperature differences and contamination as well as corrosion by condensation water and the like. In addition, they must also ensure a tensile connection between the door body and the body under extreme conditions, such as those formed by a side impact of the vehicle. In addition to this there is the fact that the door hinges for motor vehicle doors over a very long period of time, in particular the service life of the motor vehicle, require maintenance which is on the one hand maintenance-free and on the other hand consistently smooth and noiseless.
  • the two hinge halves of motor vehicle door hinges are in most cases made from appropriately machined longitudinal sections of continuous hinge profiles made of steel and connected to one another by means of a subsequently inserted hinge pin, a complex machining, in particular, of the hinge eye holes in both hinge halves being required.
  • hinge halves have already been used or proposed for molded vehicle door hinges as molded parts, in particular sintered metal parts (DE-U-9108021) or cast mold parts, this does not remove the need for complex machining, in particular the hinge eye bore of one hinge half, and an additional work process for insertion or in the one-piece design of the other hinge half for machining the hinge pin, so that by such a measure the manufacturing effort for the hinge itself cannot be reduced or can be reduced only insignificantly.
  • the production of the two hinge halves from a sintered metal does not yet enable sufficient bearing accuracy to be achieved between the hinge pin on one hinge eye and the hinge eye bore in the other hinge half.
  • the invention is therefore based on the object of providing a motor vehicle door hinge which, on the one hand, is able to withstand the loads resulting in particular from the operation of a motor vehicle and which, on the other hand, with the least possible use of technical and economic outlay as a large series part, in particular also as a divisible part, but also as a part Door arrester can be realized with a hinge manufactured in the same construction.
  • this object is achieved according to the invention in that the hinge pin connected to the hinge leaf by means of a shape and material-uniform support part is covered by a sleeve made of wear-resistant material and the second hinge half is covered by a length section of a continuous hinge profile is formed.
  • Such an embodiment of a motor vehicle door hinge has the advantage that, with regard to one hinge half, the outlay for manufacture for its manufacture as a molded part is avoided, and that hand in hand, the outlay for machining the hinge pin itself is also eliminated.
  • the interposition of a support part formed with both parts in the same shape and material between the hinge pin and the hinge leaf enables the second hinge half to be produced from a length section of a continuous hinge profile in a particularly simple and thus advantageous manner, which is characteristically provided with a head roller intended for receiving a hinge eye bore and can be machined in a known manner.
  • Such or at least similar formal and spatial design of the hinge halves is particularly important for motor vehicle doors due to the spatial installation and load conditions there.
  • such a spatial design opens up a wide field of design freedom with regard to the configuration of the mounting of the hinge eye of the second hinge half on the hinge pin.
  • a first advantageous possibility results from the inventive design of the two hinge halves from the fact that the sleeve made of wear-resistant material is positively connected in the axial direction with the hinge eye of the second hinge half and can be coupled in the circumferential direction with the hinge pin in a rotationally secure manner.
  • the hinge pin has a cross-sectional shape deviating from the pure circular shape and the sleeve made of wear-resistant material has a complementary cross-sectional shape of its clear diameter.
  • the hinge eye of the second hinge half by means of a bearing bush made of maintenance-free bearing material on the sleeve made of wear-resistant material.
  • the total axial length of the hinge pin and support part should be less than the total height of the hinge leaf of one hinge half, i.e.
  • the hinge pin and supporting part should lie within the height of the hinge leaf over their entire height.
  • any method suitable for producing molded parts is suitable for producing the one hinge half comprising the hinge pin, but it is preferably provided that the hinge half equipped with the hinge pin consists of a steel material and is formed by a forged or extruded part. However, in particular in the interest of saving weight, it can also be provided that the hinge half equipped with the hinge pin is formed by a cast part.
  • the hinge pin is provided with a surface treatment or hardening, for example case hardening, at least over part of its length.
  • the axial length of the hinge pin is greater than the axial length of the hinge eye of the second hinge half, there is a first preferred embodiment with regard to the mutual securing of the two hinge halves of the motor vehicle door hinge from the fact that the fixing of the hinge eye of the second hinge half on the hinge pin, for example, by riveting, deformation or notch, the area of the hinge pin projecting beyond the hinge eye is formed.
  • a washer is arranged between the deformation of the free end of the hinge pin and the end face of the hinge eye of the second hinge half facing it.
  • the invention also encompasses the use of conventional hinge pins in conventional designs of the connection between the hinge pin and the hinge eye, for example those in which the axial securing of the hinge eye of the second hinge half on the hinge pin by means of a screw bolt engaging in a blind hole in the hinge pin Hinge pin connecting washer is formed or those in which the hinge pin has at its free end, which projects beyond the hinge eye of the second hinge half, an area provided with an external thread and the hinge eye of the second hinge half is secured by an attached nut or the like.
  • the fixed part having the brake or detent marks of the door arrester is also formed in one piece with the hinge half having the hinge pin.
  • the motor vehicle door hinge shown overall and graphically in FIG. 1 of the drawing consists of a first hinge half 1 and a second hinge half 2, the first hinge half 1 being formed by a molded part of uniform material and a hinge pin 5 and connected by means of a support part 3 to a hinge leaf 4 the second hinge half 2 is a hinge eye 6 having.
  • the axial length of the hinge pin 5 is smaller than the total height of the hinge leaf 4.
  • the hinge half 2 is formed from a length section of a continuous hinge profile having a hinge leaf 7 and a top roller 8, the hinge eye 6 being provided by a length section provided with a hinge eye bore 9 Top roller 8 of the hinge profile is shown. It can be seen from the individual configuration shown in FIG.
  • the hinge pin 5 is covered with a sleeve 13 made of a wear-resistant material over its length that is in engagement with the hinge eye bore of the hinge eye 6.
  • the design shown in FIG. 3 and essentially corresponding to that of FIGS. 1 and 2 is further characterized in that a lining formed by bearing bushes 14 is formed between the hinge pins 5, which are clad with a sleeve 13 made of a wear-resistant material, and the hinge eye bore of the hinge eye 6 made of maintenance-free storage material is switched on.
  • the hinge pin 5 has an axial length equal to the height of the hinge eye 6 and a polygonal cross-sectional profile and a central blind hole 11.
  • a bushing 15 is inserted into the hinge eye 6, the clear cross-section of which has a profile complementary to its cross-section to produce a rotationally secure connection with the hinge pin 5.
  • the position of the sleeve 15 in the hinge eye bore secured in the axial direction is shown schematically in the drawing by a collar 16 which partially overlaps the upper and the lower commercial surface of the hinge eye 6 and 17 of the socket 15 shown.
  • the hinge eye 6 of the hinge half 2 is mounted on the outer circumferential surface of the bush 15 by means of a lining with bearing bushes 18 made of maintenance-free bearing material and designed as collar bushings.
  • the second hinge half is held by means of a washer 10 which is fixed by a screw bolt 12 screwed into the central blind hole 11 of the hinge pin 5 and which lies on the outer commercial surface 9 of the hinge eye 6.
  • a screw bolt 12 screwed into the central blind hole 11 of the hinge pin 5 and which lies on the outer commercial surface 9 of the hinge eye 6.
  • a screw bolt 12 an embodiment corresponding to the design shown in FIG. 4 can also be used.
