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.
  • 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 hinge pin that was subsequently used, an extremely complex machining, in particular of the hinge eye holes, being necessary.
  • hinge halves are already used as molded parts, in particular cast parts, for motor vehicle door hinges, this does not relieve the time-consuming processing, in particular of the hinge eye holes, and of the additional work process for inserting the hinge pin, so that the measure itself Manufacturing effort for the hinge can be reduced only slightly.
  • the formation of a rotationally secure connection of the hinge pin with one of the two hinge halves in detachable door hinges is not only associated to a particular extent, at least with regard to the design and manufacture of the hinge pin.
  • the invention has for its object to provide 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 effort as a large series part, both as simple and as divisible, but also as possible a hinge can be realized in a structurally manufactured manner.
  • this object is essentially achieved in that the one hinge half is formed by a molded part with hinge pins formed integrally therewith in terms of shape and material.
  • the hinge pin is connected to the hinge leaf by means of a support part, the hinge leaf, hinge pin and support part being formed in one piece from the same material.
  • the supporting part is replaced the hinge eye which is conventionally formed on the first hinge half, with the advantage that the second hinge half can be formed in a conventional manner by a length section of a continuous hinge profile which is machined in a known manner and is provided with a head roller intended for forming hinge eyes.
  • Such or a similar spatial design of the hinge halves is particularly important for motor vehicle doors due to the spatial installation and load conditions given there.
  • such a spatial design opens up a wide field of design freedom with regard to the design of the mounting of the hinge eye of the second hinge half on the hinge pin.
  • the total axial length of the hinge pin should be less than the total height of the hinge leaf of one hinge half, i.e. the supporting part should lie within the height of the hinge leaf over its entire height.
  • any method suitable for producing molded parts is suitable for producing the one hinge half comprising the hinge pin, but it can preferably be provided that the hinge half equipped with the hinge pin consists of a steel material and is formed by a forged or extruded part.
  • the hinge half equipped with the hinge pin is formed by a cast part.
  • the hinge half equipped with the hinge pin consists of a sintered material.
  • the hinge pin is provided with a surface treatment or hardening, for example case hardening, in particular over part of its length.
  • the hinge pin is replaced by a sleeve made of wear-resistant material, e.g. Steel that is clad.
  • This measure can, among other things, replace an otherwise possibly necessary machining of the hinge pin surface in such a way that the sleeve forms a running surface for a bearing bush made of maintenance-free bearing material.
  • the axial length of the hinge pin is greater than the axial length of the hinge eye of the second hinge half and that the hinge eye of the second hinge half is fixed to the hinge pin by deformation, for example riveting 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 in conventional hinge pins of 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 is formed by means of a screw bolt engaging in a blind hole in the hinge pin, and such a hinge pin is connected to the hinge pin or such , in which the hinge pin has at its free end projecting 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 design according to the invention of one hinge half is also outstandingly suitable for the formation of separable motor vehicle door hinges, in that the hinge eye of the second hinge half is supported by means of a bearing bush made of maintenance-free bearing material on a sleeve made of wear-resistant material comprising this, the sleeve made of wear-resistant material in Axial direction is positively connected to the hinge eye of the second hinge half and rotatably connected to the hinge pin in the circumferential direction, for example in that 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.
  • a door arrester is to be structurally combined with the door hinge, it is provided that the fixed part having the braking or latching 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 made of one material and a hinge pin 5 and the second hinge half 2 has a hinge eye 6.
  • the axial length of the hinge pin 5 is less 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 area 7 and a top roller 8, the hinge eye 6 being represented by a length section of the top roller 8 of the hinge profile provided with a hinge eye bore 9.
  • the hinge pin 5 which is in one piece with the first hinge half 1, has a greater axial length than the height of the hinge eye 6 of the second hinge half 2 and is for securing the mutual engagement position of the hinge pin 5 and the hinge eye 6 expanded in its area beyond the outside commercial area 9 of the hinge eye 6 by a central deformation 10, so that it partially overlaps the commercial area 9 and thereby represents a form-fitting securing.
  • the hinge pin 5 which is in one piece with the first hinge half 1, also has a greater axial length than the height of the hinge eye 6 of the second hinge half 2 and is in the region of its free end 11 with one of the Securing the mutual engagement position of hinge pin 5 and hinge eye 6 serving, on the outer commercial surface 9 of the hinge eye 6 washer 12 riveted.
  • the hinge pin 5 which is in one piece with the first hinge half 1, also has an axial length greater than the height of the hinge eye 6 of the second hinge half 2 and is in the region of its free end 11 with an external thread 13 provided on which a screw nut 14 is placed, by means of which a washer 12, which is used to secure the mutual engagement position of the hinge pin 5 and the hinge eye 6, is held on the outer commercial surface 9 of the hinge eye 6.
  • the hinge pin 5 which is in one piece with the first hinge half 1 has an axial length which is the same as the height of the hinge eye 6 of the second hinge half 2 and is in the region of its free end 11 with a central blind hole 15 provided in which a screw bolt 16 engages, by means of which a washer 12, which is used to secure the mutual engagement position of the hinge pin 5 and the hinge eye 6, is held on the outer commercial surface 9 of the hinge eye 6.
  • FIG. 6 The design shown in FIG. 6 and essentially corresponding to that of FIG. 5 is characterized in that the hinge pin 5 is covered with a sleeve 17 made of a wear-resistant material over its length that is in engagement with the hinge eye bore of the hinge eye 6.
  • FIG. 7 The design shown in FIG. 7 and essentially corresponding to that of FIGS. 5 and 6 is further characterized in that a lining formed by bearing bushings 18 is formed between the hinge pins 5, which are covered with a sleeve 17 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 that is the same size as the height of the hinge eye 6 and a polygonal shape Cross-sectional profile and a central blind hole 15.
  • a bushing 20 is inserted into the hinge eye 6, the clear cross-section of which has a profile complementary to the cross-section of the hinge pin 5 for producing a rotationally secure connection to the hinge pin.
  • the position of the sleeve 20 in the hinge eye bore secured in the axial direction is shown schematically in the drawing by a collar 21 and 22 of the bushing 20 partially overlapping the upper and the lower commercial surface of the hinge eye 6.
  • the hinge eye 6 of the hinge half 2 is mounted on the outer circumferential surface of the bush 20 by means of a lining with bearing bushes 23 made of maintenance-free bearing material and designed as collar bushings.
  • the second hinge half is held by means of a washer 12 fixed by a screw bolt 16 screwed into the central blind hole 15 of the hinge pin 5 and resting on the outer commercial surface 9 of the hinge eye 6.
  • a screw bolt 16 instead of a screw bolt 16, a design corresponding to the design shown in FIG. 4 can also be used.
