Definitions
- the present invention relates to a ball joint according to the preamble of claim 1.
- Ball joints of the type mentioned have a bearing shell which is snapped onto the ball and is inserted into the hollow spherical space of the ball joint housing. The ball is then fixed in the hollow sphere by rolling in a flanged edge. Tolerances occur both in the manufacture of the hollow spherical space and in the manufacture of the bearing shell and the ball, which can cause the bearing shell to fit too tightly or loosely to fit if the plus or minus tolerances collapse unfavorably.
- the object is to be achieved to narrow the tolerance of the bearing play or to eliminate it as far as possible.
- Fig. 1 is a side view of a ball joint according to the invention, partly in section and
- FIG. 2 shows a similar view of a ball joint according to the invention with a molded-on groove for the bellows.
- 1 denotes a ball joint housing which has a ball cavity 2, an upper insertion opening 3 and at least one injection opening 5, for example on the side 4 opposite this.
- a ball formed on a bearing pin 6 is inserted as a joint ball 7 with a bearing shell 8 snapped onto it through the correspondingly large insertion opening 3.
- the joint ball 7 is fixed in a suitable manner as centrally as possible in the ball cavity 2 and then back-injected with an intermediate layer 9 made of a polymerizing plastic, for example a thermoplastic.
- the injection process takes place through the injection opening 5.
- one or more further injection openings can also be provided at other points.
- the joint ball 7 is partially overlapped at the top and the insertion opening 3 is narrowed to such an extent that the bearing shell 8 and thus also the joint ball 7 in the ball cavity 2 are held securely.
- a reliable tolerance compensation is achieved by the intermediate layer 9, which in the production of joint ball 7, Bearing shell 8 and ball cavity 2 as individual elements would not be achievable even with the highest precision.
- the bearing shell 8 can be designed with one or more slits. This brings about better anchoring of the same with the back-injected material of the intermediate layer 9.
- the ball joint housing 1 has a conventional upper edge part 10 with a circumferential groove 11, into which an annular bead 12 of a bellows 13 is inserted and fixed by means of a spring ring 14.
- the other, in the drawing, upper side of the bellows 13 lies tightly against the bearing journal 6 by means of a spring ring 15.
- the ball joint housing 1 has no edge part 10 pointing upwards.
- the bearing shell 8 is provided with a circumferential support edge 16 which rests on the support surface 17 of the ball joint housing 1 which is present instead of the edge part 10.
- the supporting edge 16 has a circumferential groove 18 for inserting the annular bead 12 of the bellows 13.
- the bellows 13 is fixed in the groove 18 by means of the spring ring 14.
- the inner wall of the ball joint housing 1 or the ball cavity 2 has an unprocessed, rough surface.
- This can be an unprocessed surface in the case of a metal casting, a sheet metal part, a cold extrusion, a forged part or the like.
- the surface can, if necessary additionally, have grooves, grooves or grooves.
- the ball joint housing 1 preferably consists of a single component.
- the bearing shell 8 and / or the intermediate layer 9 consist of a polymerizing plastic, in particular a thermoplastic, preferably of one of the plastics polyethylene, polypropylene, polyoxymethylene, polyether sulfone, polyether ether ketone or polyamide.
- the bearing shell 8 preferably consists of an unreinforced plastic, while the intermediate layer 9 advantageously with a filler, for example one or more mineral fillers, optionally made of or based on glass, for example in the form of glass fibers and / or glass balls or mineral compounds in other forms , is reinforced.
- a filler for example one or more mineral fillers, optionally made of or based on glass, for example in the form of glass fibers and / or glass balls or mineral compounds in other forms , is reinforced.
