Definitions

  • the invention relates to a torsion bar door arrester for motor vehicle doors consisting of a locking device which can be attached to a door arrangement part, door or door pillar, and a torsion bar spring which can be attached to the other door arrangement part, the torsion bar spring being formed by a torsion spring bar which is non-rotatably connected to a loading arm and which is the loading arm the locking device assigned to the torsion spring bar is formed by at least two locking rollers rotatably mounted on a respective bearing journal and provided with a peripheral profile.
  • Torsion bar door locks are generally characterized in that the braking and holding force is applied by the interaction of a torsion bar spring clamped on one side in a receptacle fixedly fixed to one door arrangement part, door or door pillar, with a latching device likewise fixedly attached and having at least one detent mark having a detent device , wherein the mutual engagement of the locking device and the torsion bar spring takes place in at least one point of a circular path concentric with the door hinge axis. It is completely irrelevant whether the torsion bar door lock as an independent, i.e. is designed to be arranged independently of the door hinges or as a part combined with one of the door hinges to form a structural unit.
  • the latching device consists of a part which is oriented transversely to the door hinge axis and is fastened concentrically on its part to the door hinge axis Curved outer circumference with at least one locking mark provided segment, while the torsion bar spring is formed by an S-shaped or C-shaped spring bar, which is clamped via its one bend on the other door arrangement part and interacts 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 .
  • plastic material such a design of the locking rollers either leads to their premature wear or to extremely high manufacturing costs for the door arrester.
  • torsion bar door locks of this type (DE-PS 32 29 766) it was then provided to make the locking rollers forming the locking marks from metal and to provide or arrange them in pairs, in such a way that two at least partially with a peripheral profile provided locking rollers together form a locking mark, which has the advantage that the loading arm of the torsion bar spring is constantly in engagement with one of the locking rollers and therefore abrupt movements of the loading arm into a locking position are avoided.
  • 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.
  • the invention is therefore based on the object of improving the torsion bar door arrester of the type mentioned at the outset in such a way that noise development as a result of corrosion occurring in the locking roller bearing and as a result of tolerances is excluded.
  • latching rollers are mounted on the journals forming their bearing axes with the interposition of bearing bushes at least coated with a maintenance-free, non-metallic material.
  • the bearing bushes or their non-metallic part initially form a structure-borne noise decoupling of the locking rollers, with the result that there is a conflict they and the loading arm of a torsion bar spring possibly developing stop noises can not propagate into the body of the latching device and thus also not into the door arrangement part, door or door pillar formed as a hollow body and forming a resonance body.
  • the use of a maintenance-free bearing material 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.
  • bearing bushes consisting at least partially 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 that the intended stopping points of the door in the opening or closing direction.
  • Plastic material is preferably 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 entirely of a plastic material precipitated with a predominant proportion of fillers, the filler proportion preferably also consisting of a non-metallic material or of a soft metal such as lead or the like. Since the locking roller bearings are not loaded during the baking of the paint on the vehicle body, special stabilization of the bearing bushes is not absolutely necessary.
  • a stabilization of the bearing bushes can be advantageous, in particular with regard to a mechanical assembly of the locking rollers including the bearing bushes, which can be achieved in a first embodiment in that the bearing bushes are formed by at least two-layer multi-layer bearing bushings from a built bearing material, at least one layer being made of consists of a non-metallic material and the layer of a non-metallic material is sufficiently strong to effect structure-borne noise decoupling.
  • the bearing bushes consist, in a manner known per se, of a metal wire mesh and a coating that precipitates its gaps and covers its surfaces, from a plastic material that can be hollowed out, optionally mixed with a filler material, the metal wire mesh of the bearing bushes consisting of an inside certain
  • elastically deformable metal in such a way that a certain, slight elastic deformation of the bearing bushes is possible under the effect of the very high force peaks which suddenly occur during operation of the door arrester at its locking marks.
  • the hard stops of the load arm of the torsion bar spring possibly resulting from tolerance deviations can be absorbed on the locking rollers and their forwarding into the door arrangement part can be avoided.
  • the bearing bushes are inserted into the bearing of the locking rollers under a predetermined radial pressure, which initially results in the advantage of a play-free mounting of the locking rollers independent of all manufacturing tolerances.
  • this measure can also be used Inhibition of the willingness to rotate the locking rollers can be achieved in that an independent further movement of the individual locking rollers after their release is excluded from the load arm of the torsion bar, which also eliminates the use of disc springs or the like.
  • a braking means As a braking means.
  • the invention is not limited to the use of a specific design of a bearing bush provided at least with a coating made of a non-metallic bearing material, regardless of the preceding presentation of special design forms; rather, the use of any type of bearing bush design can be provided within the scope of the invention, which on the one hand Structure-borne noise insulation and, on the other hand, enable permanent, play-free and corrosion-free storage of the locking rollers.
  • the implementation of the invention is likewise not dependent on a specific shape for the bearing bushes, rather the shape of the bearing bushes will expediently have to be based on the properties of the non-metallic bearing material.
  • the bearing bushes can therefore be formed by pure cylinder bushes.
  • 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 as a unit, has an S-shaped bracket, which is held above its sheep part 14 with the interposition of a bearing shell 15 on the engaging hinge wing 2 and via one Support arm 16 against this supported torsion bar spring, the area bearing the load arm 17 projects beyond the two hinge wings 2 and 3 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 which are formed uniformly with one another, each of the latching rollers 18 being rotatably supported about a vertical axis on one of the projections 6 of the latching device 8 via a bearing journal 25.
  • 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 shown in the Embodiment supported by bushings 27 on the respective journal 15. 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 precipitated 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 bearing locking of the locking rollers that is free of play regardless of any manufacturing tolerances.
