Definitions

• the invention relates to a door hinge with an integrated door brake according to the preamble of claim 1 for K raftwagen doors, the one hinge wing of a first door arrangement part and the second hinge wing can be struck on another door arrangement part, and the two hinge wings are pivotally connected to one another via a hinge pin designed as a screw bolt , wherein the hinge wing which is pivotable relative to the screw bolt is mounted on a smooth-surfaced shaft part of the screw bolt.
• Door hinges are known from practice, the hinge pin of which has a smooth-faced cylindrical shaft part penetrating the hinge of two hinge wings of a door hinge and then has a threaded section on it.
• the smooth-faced cylindrical shaft part is used for the mutually pivotable mounting of the two hinge wings and the threaded section of the hinge pin either for screwing on a securing part, which is intended to prevent the hinge from falling apart, or for screwing on a decorative element that visually complements the hinge.
• caps or the like which can be screwed onto one of the two ends of a hinge pin or to seal a locking agent depot accommodated within the hinge pin.
• FR-A-1 340 951 describes a door brake structurally combined with a door hinge or a door arrester structurally combined with a door hinge, which as a hinge pin has a part engaging in the hinge eyes of two hinge wings with a central axial and conical recess, which has a cylindrical outer circumference .
• a correspondingly conical braking and locking part engages in the recess, which can be brought into a pretensioned position via a screw bolt supported against the other hinge wing such that an increased tightening of the screw bolt leads to an increased braking or locking force.
• Door brakes and door locks designed in this way can in principle be integrated into a door hinge, but they require a plurality of components, some of which can be manufactured with considerable precision, which results in considerable manufacturing and assembly expenditure.
• a disadvantage of these known types of door brakes and door locks is the need to adjust them individually with regard to the braking or holding force to be applied, whereby a specifically optimal effect can be achieved, but which is unsuitable for more modern series production.
• the door hinge according to the invention largely enables wear-free and noise-free work even when high braking and holding forces are applied.
• the integration of the door brake, which can also function as a door arrester, does not require any constructional enlargement of the two hinge wings and / or the hinge eyes, so that the door hinge can be accommodated in the usual design and also the loads which are held, in particular by the weight load of a motor vehicle door, can be worn in the same dimensions of the door hinge. No complex additional components are required for the door hinge according to the invention in order to implement the door brake.
• the door hinge according to the invention takes advantage of the fact that an axial pressure between the mutually opposite commercial surfaces of the hinge can be derived from an axial expansion of the hinge pin moving in the area of its elastic deformation and can therefore also be derived from Relatively high braking forces, at least in principle, do without the use of special braking agents, such as brake discs or the like.
• the nut thread is formed in the hinge eye of the other hinge, so that a threaded screw bolt can turn its thread against the nut thread.
• the nut thread assigned to the hinge pin forming screw thread is arranged in an axial extension of the hinge eye of the other hinge wing connected to the latter and non-rotatably connected to the abutment part.
• the screw bolt is expediently equipped with a head having a tool attachment and the rotationally secure connection of the one hinge wing to the screw bolt whose head is arranged adjacent, in which case the screw bolt, which forms the hinge pin via a smoothly cylindrical shaft section, for the purpose of enforcing an axial elongation in its elastic deformation area is inevitably dependent on the opening movement of the door associated with the female thread in an axial extension of the hinge pin on the hinge pin of the other hinge wing.
• a friction-reducing pressure distribution element is switched on.
• a further measure deemed expedient for a hinge design which cannot be separated according to the intended purpose consists in the fact that the screw bolt forming the hinge pin, which has a smoothly cylindrical shank section, has a reduced diameter compared to its bearing section in its threaded area and that this extends the hinge eye bore of the other hinge wing formed nut thread of the hinge eye bore compared to a smaller clear diameter.
• the threaded portion of the screw bolt forming the hinge pin be equipped with a saw thread.
• the friction-avoiding pressure distribution element connected between the two mutually facing commercial surfaces of the hinge eyes of the two hinge wings either in a somewhat more complex manner than a thrust bearing or in a more simple design is designed as a normal thrust washer.
• the application according to the invention also includes an application of the aforementioned measures which changes from the commercial area of one hinge eye to the commercial area of the other.
• the bolt forming the hinge pin via a smooth cylindrical barrel section is constructed in the same construction and material as the one hinge wing and the abutment part containing the nut thread associated with the threaded section of the screw bolt can be fixed in a predeterminable screw-in position of the threaded section of the screw bolt on the other hinge wing is.
• a further modified embodiment of a door hinge for motor vehicle doors equipped with an integrated door brake can be characterized in that the screw bolt, which forms the hinge pin via a smoothly cylindrical shaft section, by means of a counter-rotating thread, in particular a fine thread, by means of a thread section which interacts with the saw thread with the mother thread in the other hinge wing , in which a hinge wing is fixed.
• FIG. 1 shows a perspective schematic view of a preferred exemplary embodiment of a door hinge according to the invention for motor vehicle doors with an integrated door brake;
• FIG. 2 shows a longitudinal section through the hinge mounting of the door hinge from FIG. 1
• the wing hinge 0 shown schematically in Fig. 1 comprises a first hinge wing 1 and a second hinge wing 2.
• the first hinge wing 1 comprises a hinge eye 3 and a hinge leaf 5.
• the second hinge wing 2 also includes a hinge eye 6 and a hinge leaf 8.
• openings 4 and 7 are provided in the form of bores or continuous recesses, which serve to connect the hinge leaf 1 or 2 by means of (not shown) fastening screws with a door arrangement part, the door or the door pillar in the same way as the door arrangement part Come into consideration.
• the openings are arranged in the corners of the hinge leaves 5 and 8, so that they are laterally offset from one another at different heights. It can also be seen in particular in FIG. 2 that the first hinge wing 1 arranged at the top in the area of its hinge eye 3 is only about half as high as the second hinge wing 2 arranged at the bottom in the area of its hinge eye 6.
• a hinge pin which connects the two hinge wings 1 and 2 to one another in a swivel joint, is designed as a screw bolt 10, which has a cylindrical shaft section 9 and a polygonal head serving as a tool attachment, the shaft section 9 in the hinge eye 3 of the first hinge wing 1 being rotationally secure in a known manner is set.
• the shaft section 9 of the bolt 10 is freely rotatably supported by means of a bearing bush 13 made of a maintenance-free bearing material.
• the shaft section 9 passes through the hinge eye 6 approximately in half.
• the screw bolt 10 has a length region 14 in which the screw bolt 10 has a reduced diameter and is provided with a thread 15 formed as a sawtooth thread.
• An extension of reduced diameter of the eye bore 12 of the hinge eye 6 is assigned to the length region 14, the extension being formed with a nut thread 16. It can be seen in particular in FIG. 2 that the length region 14 does not completely penetrate the extension, but rather that there is a free space beyond the length region 14 of the bolt 10.
• the wing hinge 0 creates an inexpensive and structurally simple integrated door brake in that a pivoting movement of the first hinge wing 1 directed about the hinge axis 20 denotes forcibly screwing in the length region 14 of the screw bolt 10, which is designed as a threaded section, into the nut thread 16 in the other hinge wing 2 and thus necessarily leads to an axial expansion of the screw bolt 10, which results in an increasing braking or holding force for the door with increasing opening angle of the door (corresponding to the opening angle of the two hinge leaves 5 and 8).
• the expansion is canceled due to the twisting section 14 being unscrewed again, so that the braking characteristics of the door brake created by this measure are reproducible.
• the expansion of the bolt mainly takes place in the area of the elastic change in shape due to tensile stress, and that this results in reproducibility on the one hand, but on the other hand also a linear characteristic curve between force and expansion a constant or linear increase in the braking force or the locking force when the door opens (or decreases when the door closes) via the EmscUagwinkel guaranteed.
• the head 11 of the bolt 10 is expediently also the stop, which prevents the bolt 10 from moving downward by screwing into the thread.
• this function can also be achieved solely by the rotationally secure arrangement of the shaft section 9 in the hinge eye 3 of the first hinge wing 1, for example by an interference fit.
• the bearing bush 13 is designed as a collar bush, a collar 17 of the bearing bush 13 engaging between the mutually facing commercial surfaces 18 and 19 of the two hinge eyes 3 and 6.
