Definitions

  • the invention relates to a torsion bar door lock for motor vehicle doors from a on a door arrangement part, door or door pillar, locking device and a torsion bar spring which can be struck on the other door arrangement part, in which the torsion bar spring is formed by a torsion spring rod connected in a rotationally secure manner to a loading arm and in which the latching device assigned to the loading arm of the torsion spring bar by at least two rotatably mounted on a bearing journal and with a circumferential profile provided locking rollers is formed, the locking rollers with interposition of bearing bushes at least coated with a maintenance-free, non-metallic material are mounted on the pins forming their bearing axles.
  • Such a torsion bar door arrester is known from US-A-3 550 185.
  • Torsion bar door locks are basically characterized in that the braking and holding force by the interaction of one in a door arrangement part, door or door pillar, fixedly attached receptacle clamped torsion bar with one on the other Also fasten the door arrangement part fixed and at least one locking mark having locking device is applied, the mutual engagement of locking device and torsion bar spring concentric in at least one point to the door hinge axis Circular orbit. It is completely irrelevant whether the torsion bar door lock as independent, i.e. unit to be arranged independently of the door hinges or but formed as a part combined with one of the door hinges is.
  • the latching device consists of a segment which is oriented transversely to the door hinge axis and fastened to a door arrangement part and is provided with at least one latching mark on its outer circumference which is concentrically curved to the door hinge axis, while the torsion bar spring is bent by an S or C shape Spring rod is formed, which is clamped via its one bend on the other door arrangement part and cooperates with the locking device via its other bend.
  • the locking marks of the latching device have been formed by at least partially provided with circumferential profiling abutment rollers in an improved type of torsion bar door arrester .
  • One of these known types of door locks (US Pat. No. 3,550,185) provides for further reduction of the noise development resulting from the falling of the loading arm of a torsion bar spring into a latching position that the latching rollers are formed entirely from a plastic material so as to achieve structure-borne sound insulation .
  • Such types of door locks can only guarantee effective noise reduction if a continuous contact of the load arm of the torsion bar spring with the locking rollers is guaranteed over the entire door opening angle.
  • first and foremost compliance with their mutual alignment is necessary, such that in the course of the opening or.
  • Closing movement of the loading arm of the torsion bar spring from the circumferential profiling of the one can slide seamlessly into the circumferential profiling of the adjacent locking roller, which naturally presupposes that a relative mutual rotation of the locking rollers can occur neither in the course of the opening nor in the course of the closing movement of the door, ie that the mutually complementary circumferential profiles of two mutually adjacent locking rollers must always maintain the same, predetermined mutual alignment position with respect to one another in both directions of rotation.
  • the invention is therefore based on the object torsion bar lock of the aforementioned To improve the design in such a way that a noise development as a result of both Locking roller bearing corrosion occurring as a result of tolerances is excluded.
  • the bearing bushes are constructed from a metal wire mesh and a coating that fills the gaps and covers the surfaces thereof from a plastic material that can be hollow and optionally filled with a filler material.
  • the bearing bushes or their non-metallic portion that is, their portion consisting of a plastic material, initially form structure-borne noise decoupling of the locking rollers, with the result that stop noises which may develop between them and the loading arm of a torsion bar spring do not enter the body of the locking device and thus also cannot propagate into the door arrangement part, door or door pillar which is designed as a hollow body and forms a resonance body.
  • the use of a maintenance-free bearing material for the representation of the bearing bushes also prevents the formation of corrosion within the locking roller bearings, so that sound developments, in particular the development of squeaking noises, are also excluded.
  • the use of at least partially made of an at least limited elastic material, such as non-metallic bearing materials leads to the exclusion of play development within the locking roller bearings and thus on the one hand to eliminate a source of noise and on the other hand to ensure the consistently precise adherence to the intended breakpoints of the door in the opening - or closing direction.
  • Plastic material is suitable as the non-metallic bearing material, since this material has both structure-borne sound insulation and excellent dry running properties.
  • the bearing bushes consist of a metal wire mesh and a coating that fills its gaps and covers its surfaces, and of a plastic material that is capable of forming hollow shapes, optionally mixed with a filler material.
  • the metal wire mesh of the bearing bushes is prefabricated from a metal which is elastically deformable within certain limits, such that a certain, slight elastic deformation of the bearing bushes is possible under the effect of the very high force peaks that suddenly occur during operation of the door retainer at its locking marks.
  • the filler content preferably also consists of a non-metallic material or of a soft metal, such as lead or the like.
  • Embodiment can be achieved in that the bearing bushings by at least two-layer multi-layer bearing bushes made of a built bearing material are, wherein at least one layer consists of a non-metallic material and wherein the layer made of a non-metallic material is sufficiently strong to decouple structure-borne noise to effect.
  • the bearing bushes under a predetermined radial pressure in the storage of the locking rollers are used, from which the advantage of an independent of all manufacturing tolerances play-free storage of the locking rollers results.
  • this measure can also an inhibition of the willingness to rotate the locking rollers can be achieved in that a independent further movement of the individual locking rollers after their release from the loading arm the torsion bar is excluded, which also the use of disc springs or the like. Is unnecessary as a braking means.
  • the implementation of the invention is not of a specific shape for the Bearing bushes dependent, rather the shape of the bearing bushes will be appropriate according to the properties of the non-metallic bearing material.
  • the Bearing bushes can therefore be formed in the simplest case by pure cylinder bushes. In various applications, it may also be advantageous that the bearing bushes designed as collar bushings and with their collar overlapping the underside of the locking rollers are arranged.
  • the assembly shown in the drawing consisting of a hinge and a hold-open device, for example for detachable motor vehicle doors, consists of a hinge with two hinge wings 2 and 3 pivotally connected to one another by means of a hinge pin 1, one of which 2 remains on the door body (not shown in the drawing) and the other 3 Can be detachably attached to the door pillar (also not shown in the drawing) and a torsion bar door lock 4.
  • the hinge wing 3 can be releasably attached to the door pillar and is formed from a U-shaped sheet metal blank, with the upper leg 5 of the U-shape directed transversely to the hinge axis formed from alternately successive projections 6 and recesses 7 locking device 8 of the door retainer 4 and on the lower, transverse to the hinge axis leg 9 of the U-shape a parallel and in the same direction to a hinge height extension 10 of the Sc hinge pin 1 directed pin-shaped projection is formed.
  • the hinge wing 2 has an approximately L-shaped cross-sectional shape and is arranged engaging in the hinge wing 3, whereby it is rotatably connected to the hinge wing 3 by means of its one profile leg via the hinge pin 1 and is fastened to the door via its other profile leg 13.
  • the torsion bar door arrester 4 which is connected to the hinge in terms of construction, has an S-shaped torsion bar spring, which is supported above its sheep part 14 with the interposition of a bearing shell 15 on the engaging hinge wing 2 and is supported against it via a support arm 16, the area of which supports the loading arm 17 Hinge wings 2 and 3 protrude upwards.
  • the loading arm 17 of the torsion bar spring interacts with the locking device 8 of the door arrester 4, which is formed on one leg 5 of the U-shape of the hinge wing 3 and consists of projections 6 and depressions 7 arranged in alternating succession, comprising three locking positions for the door.
  • the latching means of the latching device 8, which cooperate with the loading arm 17 of the door arrester, are formed here by three latching rollers 18 of uniform design, each of the latching rollers 18 being rotatably supported on one of the projections 6 of the latching device 8 via a bearing pin 25 about a vertical axis.
  • the locking rollers 18 are formed uniformly over their entire height and are equipped on both sides of a circular cross-sectional shape formed in a central region 19 with oppositely arranged and symmetrical, radially directed projections 20 and 21, the one radial projection 20 being provided with a latching recess 22 and the other radial projection 21 is wedge-shaped with a smooth surface.
  • the latching recess 22 in the radial projection 20 has a contour that corresponds to the circular cross-sectional shape of the loading arm 17 of the torsion bar spring, such that the quarter-circular latching recesses 22 of two adjacent and mutually pivotable latching rollers 7 complement each other to form a semicircular shape.
  • the two flank surfaces 23 and 24 of the smoothly wedge-shaped radial projection 21 of each of the latching rollers 18 each form an angle of 97 ° with one another, so that the smoothly wedge-shaped projections 21 of adjacent latching rollers 18 each form a mutual pivoting end stop for the latching rollers 18, which is the maximum possible pivoting angle range of adjacent locking rollers 18 is limited to an angular amount of 97 °.
  • the locking rollers 18 are mounted on the respective journal 25 via bearing bushes 27 in the exemplary embodiment shown. In the embodiment shown schematically and only by way of example in FIG.
  • the bearing bushes 27 consist of a metal wire mesh 29 coated with a maintenance-free, non-metallic bearing material, the non-metallic bearing material consisting of a plastic material filled with non-metallic fillers and at the same time also filling the gaps 30 of the wire mesh and is anchored in this way to the metal wire mesh 29.
  • the metal wire mesh 29 of the bearing bushes consists of a non-ferrous metal that is elastically deformable within certain limits.
  • the metal wire mesh 29 only forms a support structure for the coating 28 and it can be seen that the coating 28 on both sides of the metal wire mesh 29 forms a layer separating the metal wire mesh 29 from the bearing walls of the locking rollers.
  • the bearing bushes are inserted into the bearing of the locking rollers under a certain radial pressure, which results in a bearing-free mounting of the locking rollers that is independent of all manufacturing tolerances.
