Definitions

  • the present invention pertains to a process for manufacturing a ball and socket joint. It pertains, furthermore, to a ball and socket joint manufactured according to that process, wherein especially the joint shell or bearing shell of the ball and socket joint is designed according to the present invention in a special manner.
  • Ball and socket joints transmit and absorb forces from several directions. They are used, for example, in the manufacture of vehicles in the area of the steering or the track rod.
  • Bearings of this class comprise essentially a pivot pin, at one end of which a ball is formed, a shell accommodating the ball of the pivot as well as a joint housing receiving the shell and parts of the ball pivot.
  • the ball of the ball pivot slides in the prestressed, permanently lubricated shell, which is protected by the housing against moisture and dirt.
  • the joint housing is, moreover, protected additionally by a sealing bellows against dirt as well as against the escape of the lubricant on its side on which it is open for receiving the pivot.
  • a rear-side opening of the joint housing which is, moreover, frequently provided, is closed by a closing cover.
  • the above-mentioned joint components are usually manufactured separately and subsequently fitted together in an assembly process. However, this can be considered to be disadvantageous in respect to the assembly effort.
  • the object of the present invention is therefore to propose a process, which makes possible the manufacture of a completely assembled ball and socket joint and as a result of which a reliably functioning ball and socket joint with a low moment of friction as well as with a low torque and overturning moment is obtained, in which sufficient lubrication of the sliding surfaces of the ball and socket joint and of the joint shell or bearing shell is ensured. Furthermore, a ball and socket joint that can be manufactured with this process shall be described.
  • Both the process proposed for accomplishing the object and the ball and socket joint that can be manufactured according to that process pertain to a ball and socket joint of a type that is known, in principle.
  • This comprises a pivot pin with a joint ball formed at one end of the pivot pin; a joint housing, which receives the joint ball and is open on one side; a permanently lubricated, essentially spherical joint shell, which is arranged between the joint ball and the joint housing; and a sealing bellows closing the open side of the joint housing in the area of the transition between the joint ball and the shaft of the pivot pin projecting from the joint housing.
  • the corresponding ball and socket joint is manufactured such that the joint housing is produced in an injection or casting process (for example, diecasting), in which the joint ball with the bearing shell placed on it is surrounded by a metallic material or a plastic.
  • the design of the joint shell which is spherical, in principle, is slightly modified according to the present invention.
  • the joint shell is provided for this purpose, in at least one area, with a bulge, which behaves elastically in relation to the pressure acting during the injection or casting process and bulges slightly outwardly after the conclusion of the injection or casting process in relation to the otherwise spherical shape of the joint shell or bearing shell. It is achieved as a result that the joint shell is not in contact with the joint ball over its full surface after the injection or casting process.
  • the joint shell designed in the above-described manner is placed on the joint ball of the pivot pin and extrusion coated together with same.
  • the sealing system is finally complemented with the sealing bellows in an assembly process following the injection or casting process.
  • a metallic cover can be advantageously formed between the joint ball and the joint housing in a ball and socket joint with metallic joint housing in the course of a casting process.
  • the joint housing is designed now such that it extends nearly up to the transition between the joint ball and the shaft of the pivot pin, the diameter of the joint housing in the area of its opening through which the pivot pin passes being smaller than the diameter of the joint ball. The resistance of the pivot pin to tearing out advantageously increases because of the metallic cover ensured hereby.
  • the joint housing is provided with a shaft, in which a correspondingly shaped tube or a rod is also extrusion-coated in the course of the manufacture of the joint housing.
  • a shaft stub at the joint housing during the injection or casting and to arrange a tube or a rod to be connected thereto by driving in in the cold or hot state.
  • the joint or bearing shell consists of a plastic, which is elastically deformable at least in the area of this bulge.
  • the elastically deformable bulge of the bearing surface placed previously on the joint ball is pressed onto the surface of the joint ball during the injection or casting process carried out to prepare the joint housing.
  • the bulge arches, at least partially, again outwardly after the end of the injection or casting process due to the special shaping and the selection of a corresponding, elastic material, for example, polyoxymethylene, polyamide, polyphenylene sulfide or polyphthalamide.
  • the joint shell has, moreover, a ribbing in the area of the outwardly arching bulge on its inner surface. This ribbing is provided for the event the bulge exceptionally fails to spring back in the particular case after the conclusion of the injection or casting process because of tolerances concerning the pressure prevailing during the injection or casting process or of tolerances concerning the material and the shape of the joint shell. It is ensured by the ribbing in this case that the joint shell will not nevertheless lie with its full surface on the joint ball.
  • the ribbing mentioned may have different shapes from a geometric point of view.
  • a plurality of ribs extend, starting from the pole of the essentially spherical geometry, on the inner surface of the outwardly arched area of the joint shell, and a plurality of ribs arranged in parallel to each other as well as to the equator of the joint ball extend at right angles thereto.
  • the joint shell has a plurality of ribs, which intersect at right angles relative to a surface projection of the spherical surface, on its inner surface in the area of the outwardly arching bulge.
  • the ball shell preferably has, moreover, on the outer surface, a plurality of longitudinally extending rib-like sections, by which a means offering security against rotation is formed. This prevents rotation of the joint shell in the joint housing.
  • a ring whose section projecting from the opening of the joint housing forms the seat for the sealing bellows, is inserted in the area of the opening of the joint housing between the joint housing and the joint shell in another preferred embodiment.
  • the metallic cover between the joint housing and the joint ball is advantageously further increased hereby in case of a metallic joint housing.
  • FIG. 1 is a partial sectional view showing a first embodiment of the ball and socket joint according to the present invention with a tubular shaft;
  • FIG. 2 is a partial sectional view showing a ball and socket joint comparable to the embodiment according to FIG. 1 , whose housing is connected to a rod;
  • FIG. 3 is a partial sectional view showing another embodiment with a tubular shaft
  • FIG. 4 is a partial sectional view showing an embodiment with a disk inserted in the area of the housing opening between the joint shell and the housing;
  • FIG. 5 a is a perspective view showing one embodiment of the joint shell.
  • FIG. 5 b is another perspective view showing another embodiment of the joint shell.
  • FIG. 1 shows a possible embodiment of the ball and socket joint according to the present invention.
  • This comprises, a pivot pin 3 , 4 , whose joint ball 4 (known per se) is accommodated by a joint housing 7 .
  • a permanently lubricated joint shell 1 , 1 ′ is arranged between the joint housing 7 and the joint ball 4 .
  • the embodiment being shown was manufactured by placing the joint shell 1 , 1 ′ on the joint ball 4 and subsequently preparing the joint housing 7 by extrusion coating or casting around the joint shell 1 , 1 ′ and the joint ball 4 .
  • the sealing system was complemented with the sealing bellows 8 in a subsequent assembly operation.
  • the joint shell 1 , 1 ′ was designed in a special manner according to the basic idea of the present invention. As can be recognized, it has an outwardly arching bulge in the area of the pole 5 of the joint ball 4 . In addition to this, a ribbing 2 is provided on the inner surface of the joint shell 1 , 1 ′ in the area of this bulge 1 ′. Full-surface contact between the joint shell 1 , 1 ′ and the joint ball 4 is prevented by these measures pertaining to the shaping of the joint shell 1 , 1 ′.
  • a shaft 12 intended to be connected to additional elements is an integral part of the joint housing 7 in the ball and socket joint shown in FIG. 1 .
  • a metallic tube 13 is also extrusion coated for this during the manufacture of the joint housing.
  • FIG. 2 shows an embodiment of the ball and socket joint according to the present invention, which is comparable, in principle, to FIG. 1 .
  • a rod 13 ′ is jointly extrusion coated here instead of a tube 13 to form the shaft 12 .
  • the contact shoulder of the ball pivot is designed in the form of a polygon 14 .
  • the service friendliness of the component is improved hereby.
  • a disk 15 is also pressed onto the pin or the shaft 3 of the ball pivot 3 , 4 under the polygon 14 .
  • FIG. 3 shows other embodiments, which are likewise comparable, in principle, to the embodiments explained above.
  • a stub 12 ′ is prepared by injection here on the joint housing 7 to form a shaft, and this stub is connected to a tube 13 , for example, by driving in, in the cold state.
  • FIG. 4 shows a variant of the ball and socket joint according to the present invention, in which an additional ring 11 is inserted between the joint shell 1 , 1 ′ and the joint housing 7 in the area of the shell's opening and extrusion coated at least partially.
  • the cover one speaks of a metallic cover in case of a metallic joint housing 7
  • the resistance [of the ball pivot] to tearing out is further increased.
  • the ball and socket joint is sealed by a sealing bellows 8 attached after the extrusion coating or casting process against contamination and against the escape of lubricant.
  • FIG. 5 shows possible embodiments of the joint shell 1 , 1 ′ of the ball and socket joint according to the present invention.
  • the joint shell 1 , 1 ′ has, corresponding to the idea of the present invention, a slightly outwardly arching bulge 1 ′ in the area of pole 5 ′. Its inner surface is contoured by a ribbing 2 in the area of this bulge. Examples of this ribbing 2 are described below under a) and b).
  • a plurality of ribs 2 ′ extend in a radiate pattern starting from pole 5 ′.
  • a plurality of ribs 2 ′′ parallel to one another and to the equator of the ball extend at right angles to these.
  • a plurality of ribs 2 ′′′ crossing at right angles relative to the surface projection of the spherical surface of the joint shell 1 , 1 ′ are formed in the embodiment according to b).
  • the rib structures shown are shown in the figure as examples and separately from the outer shape of the joint shell 1 , 1 ′ for the sake of better illustration only. However, they are always made in one piece with the joint shell 1 , 1 ′.
  • the joint shell 1 , 1 ′ shown in the figure has, moreover, a plurality of ribs 10 or webs on its outer surface, which are used as means for securing against rotation and prevent the rotation of the joint shell 1 , 1 ′ in the joint housing 7 .
