Definitions

  • the invention relates to door hinges for opening and closing the doors of a motor vehicle according to the preamble of claim 1.
  • Each door usually has two door hinges.
  • Each door hinge usually consists of a first hinge part which is fixedly connected to the frame or the body of the motor vehicle, and a second hinge part which is fixedly connected to the door. Both hinge parts are pivotally connected to one another via an axis.
  • the doors of motor vehicles usually also have a locking device which allows the door to be held in an open and a partially open position. Thanks to a spring, no additional forces are required.
  • Door hinges of this type mostly use torsional forces to brake the movement of the second door hinge, to prevent undesired swinging of the door and / or to allow the door to swing gently back into the closed position.
  • the object of the present invention is therefore to provide a door hinge which is compact, light, durable and can be adapted to the particular application without major structural changes.
  • the first hinge part consists of a base plate and an arm.
  • the spring is anchored at one end of the base plate, while the arm is formed on the opposite end of the base plate and extends from the base plate to the hinge axis.
  • the arm consists of two parallel arms, which extend from the base plate to the hinge axis.
  • the parallel arms have aligned holes through which the hinge axis can be inserted.
  • the second hinge part comprises two opposite, essentially parallel side walls with aligned bores for the hinge axis.
  • two rotatable locking devices are provided, in particular in the form of rollers, the end face of which is perforated and which run on axis pins which are parallel to one another.
  • the spring cooperates with these rotatable locking devices such that the first locking device engages the spring when the door is closed, both locking devices engage the spring when the door is in a central position, and the second locking device engages the spring when the door is fully open.
  • the central position and open position of the door can be easily adjusted by simply laying the locking devices or the axle pins.
  • the resultant spring force can be influenced despite the use of one and the same spring. Thanks to the rolling movements, the wear, especially of the spring, is negligible, so that a long service life of the door hinge and the integrated locking device can be expected.
  • the spring consists of a bent metal rod which has a first and a second end, which are anchored to the base plate of the first hinge part.
  • the metal rod is then bent close to the two ends by approximately 90 degrees in such a way that a section of the metal rod runs along the base plate over a defined length.
  • the metal rod is then bent upwards, away from the base plate in the direction of the second hinge part.
  • the metal rod is bent vertically again, so that a common spring section is formed which runs essentially parallel to the base plate of the first hinge part and is in contact with the second hinge part or the rotatable locking devices attached there.
  • the ends of the metal rod are either directly in a hole in the base plate or in holes in two tabs that are bent out of the base plate. anchored.
  • both hinge parts cannot consist only of steel or sheet steel; rather, they can also consist of fiber-reinforced plastics or high-strength light metals.
  • the parallel sections of the metal rod, which run along the base plate, are supported on separate wedge parts on opposite sides of the base plate.
  • the position and angle of the wedge parts allow another very simple variation of the spring parameters.
  • the two arms of the first hinge part are mechanically connected to one another in the region of the hinge axis, for example by welding a web plate or a piece of pipe, which surrounds the hinge axis, between the arms.
  • Fig. 1 shows the installation situation for door hinges in motor vehicles.
  • a vehicle frame 10, a dashboard 16 and a vehicle door 12 with a window 14 can be seen.
  • a door hinge 18 with an integrated door retainer is provided in order to be able to open and close the vehicle door 12.
  • the door hinge 18 is firmly connected on the one hand to the frame 10 of the vehicle 20 and on the other hand to the door 12. Thanks to the locking device to be described, the door 12 can be opened against a spring resistance and in a partially open middle position and a fully open end position being held.
  • the door hinge 18 is usually made of steel or sheet steel and is formed by rolling or forging or by stamping and bending. Manufacture from high-strength light metal or high-strength fiber-reinforced plastics is also possible.
  • the door hinge 18 consists of a first hinge part 22 and a second hinge part 24 which are connected to one another in an articulated manner by means of a hinge axis 26.
  • a compression spring 28 is firmly anchored to the first hinge part 22. It abuts the second hinge part 24 in such a way that the spring 28 is compressed by the second hinge part 24 when it rotates on the hinge axis 26.
  • the spring 28 is made of spring steel, as will be described below.
  • the first hinge part 22 essentially consists of a flat base plate 30 and an arm 32 projecting therefrom. Holes 34, 35 in the base plate 30 enable the door hinge 18 to be screwed to the vehicle frame 10. Other fastening methods, for example welding, are also possible.
  • the arm 32 is angled relative to the base plate 30 and connected to the hinge axis 26 via a bushing 56 made of permanently lubricable material. For the purpose of connection to the hinge axis 26 or the second hinge part 24, the arm 32 is tapered in a suitable manner (FIG. 4).
  • the base plate 30 has an elevation 36, in the bores of which the ends 38, 40 of the Compression spring 28 are anchored.
  • the spring 28 is then bent essentially by 90 degrees, so that first spring sections 42, 44 are formed, which run essentially parallel to the base plate 30 and are supported against wedge sections 46, 48 which are laterally on the base plate 30 are molded.
  • the base plate 30 has a T shape.
  • the spring is then bent upwards / backwards, as a result of which two second spring sections 50, 52 are formed. These are then bent towards one another essentially by 90 degrees, so that a common transverse section 54 is formed.
  • This cross section 54 is approximately parallel to the base plate 30 and touches the second hinge part 24, as will be described in more detail below.
  • the second hinge part 24 has a base plate 70 with bores 72, 73 for screw fastening on the door 12. Other fastening options such as welding can also be provided here.
  • Two substantially parallel side walls 58, 60 rise from the base plate 70 (FIG. 4). They are connected to one another via a connecting web 68.
  • Aligned holes are provided in the side walls 58, 60 through which the hinge axis 26 is inserted.
  • the permanent connection is made with the aid of a head 62, a washer 64 and a rivet head 66 (see FIG. 5).
  • rollers 74, 76 with a profiled end face are fastened to the side walls 58, 60. Both rollers 74, 76 are rotatably seated on mutually parallel axle pins 78, 80 on the outside of the side walls 58, 60.
  • the axle pins 78, 80 each have a head which lies against the outside of the rollers 74, 76 and are corrugated 61 provided and riveted in the side wall 58, 60 by means of a rivet head 82, 84.
  • one or both rollers 74, 76 are supported on the transverse section 54 of the spring 28.
  • FIG. 5 is a section along the line V-V through the hinge 18 of FIG. 2 in order to be able to show the position of the hinge axis 26 exactly.
  • the hinge axis 26 is pushed through the arm 32 with the aid of the bushing 56. It also extends through the bores in the side walls 58, 60. The ends of the hinge axis 26 protrude only slightly beyond the side walls 58, 60.
  • One end of the hinge axis 26 has a corrugation 61 in order to prevent the hinge axis 26 from rotating.
  • the head 62, the washer 64 and the round rivet head 66 hold the hinge axis 26 in position so that the second hinge part 24 can rotate about the hinge axis 26.
  • the roller 74 attached to the side wall 58 can also be seen.
  • the roller 74 is attached to the side wall 58 by means of a corrugated axle pin 78 which has a securing element 82 on the inside of the side wall 58.
  • the roller 74 cannot be rotated; the cross section 54 of the spring 28 is engaged with a recess of the roller 74.
  • FIG. 6A is essentially identical to FIG. 2.
  • the transverse section 54 of the spring 28 presses against a depression on the roller 74, as shown.
  • the door 12 is screwed to the base plate 70 of the second hinge part 24.
  • the second hinge part 24 rotates counterclockwise about the hinge axis 26.
  • the roller 74 is pressed downward against the transverse section 54 of the spring 28, thereby compressing it.
  • the spring force counteracts the opening of the door 12.
  • the spring 28 is compressed, the first spring sections 42, 44 are pressed against the wedge sections 46, 48 of the base plate 30.
  • the door 12 can be moved into the fully open position by the vehicle user, as shown in FIG. 6C.
  • the transverse section 54 of the spring 28 presses against a recess in the roller 76.
  • the spring 28 is under only slight pressure, if at all.
  • the spring 28 is essentially compressed only when the door 12 is pivoted from one position to the other.
  • rollers 74, 76 can be changed in their absolute and relative position, that they can have different diameters and / or different shapes of the recesses, so that the middle position according to FIG. 6B can be changed accordingly.
  • the design principle described offers a large number of advantages.
  • the main advantage is that the spring 28 works as a compression spring, not as a torsion bar spring. This enabled the fatigue strength to be significantly improved. A corresponding test series was terminated after practically no signs of wear were recognizable with more than twice the number of movement cycles normally prescribed.
  • the same spring 28 can be used together with a large number of differently constructed and differently heavy doors.
  • the diameter of the spring does not have to be changed, rather it is sufficient to change the position of the wedge parts 46, 48, which is very easy to do.
  • the door hinge 18 is very compact and can also be used in very spatially limited constructions, for example if additional electrical lines have to be laid between the vehicle and the door.
  • the weight of the door hinge could be reduced considerably, which affects the fuel consumption of the motor vehicles.
  • a door hinge according to the present invention only weighs about 770 g, while conventional door hinges with an integrated hold-open device weigh about 1150 g.
  • FIGS. 7 and 8 On the one hand and FIG. 9 on the other hand are completely punched out of sheet steel and bent.
  • the positions which correspond to the hinge of FIGS. 2 to 6 have been given the same reference numerals, with a "1" being prefixed in each case.
  • FIG. 7 and 8 show a door hinge 118, in which the ends 138, 140 of the spring 128 are fixed in bores of bent tabs 135, 137.
  • the tabs 135, 137 allow a further reduction in weight.
  • two approximately parallel arms 129, 131 are provided. They have aligned holes through which the hinge axis 126 is inserted. Bushes 156 provide the necessary permanent lubrication.
  • the side walls 158, 160 of the second hinge part 124 are positioned between the two arms 129, 131.
  • the rollers 174, 176 are positioned on the inside of the side walls 158, 160.
  • the spring 128 is threaded through oval bores in the arms 129, 131 so that its cross section 154 touches one or both rollers 174, 176 depending on the position of the door.
  • FIG. 9 shows a variant of the door hinge 118, which is only produced from stamped and bent parts, in which the two arms 129, 131 are again positioned between the side walls 158, 160 of the second hinge part 124.
  • the two arms 129, 131 are angled, as already described with reference to FIGS. 2 to 6.
  • a tube piece 133 is welded in between. This piece of pipe 133 thus simultaneously protects the hinge axis 126.
  • the Connecting web 68, 168 lies from above against arm 32 or parallel arms 129, 131 if door 12 should be torn open beyond the open position, for example by a gust of wind.
  • the connecting web 68, 168 thus simultaneously acts as a security element.
