A sealing cap is usually used to prevent foreign matter used, which is held at one end around the socket component and engages around the ball pin at the other end, wherein the end of the cap, which sits on the ball stud, has an inner diameter that is slightly smaller than the diameter of the Ball stud is so that the cap is stretched when it is mated with the ball stud, and in this way under Tension is printed against the surface of said ball stud. However, the radial pressure must be as low as possible, however, while maintaining the seal between the ball stud and the cap, because the ball stud is in the sealing cap Must be freely rotatable and wear should be kept to a minimum.

The sealing cap is made of elastic material, and if the ball pin is at an angle to the joint socket, then is the sealing cap on one side under tension, which tends to the end of the cap, which the ball pin surrounds to be removed from the surface of the ball stud on this side « This places the pressure normally exerted on the ball stud by the sealing cap on a part its periphery is reduced, and the sealing effect is reduced .

It is the task of the innovation to create a sealing cap, in which these disadvantages are eliminated and the pressure between the cap and the ball pin remains essentially constant.

According to the invention, the sealing cap has a ball joint connection a sleeve-shaped component made of elastic Material on which at one end around the socket component d.the connection is clamped and at the other end with a Bead is provided, with an annular collar made of rigid material of substantially L-shaped cross-section is provided, wherein a Legs of the same engages the radially outer surface of the bulged end, while the other leg extends inward extends in the direction of the ball stud, the annular collar is freely rotatable on the ball pin and the relative dimensions of the bead, collar and ball pin are such that the beaded end of the sealing cap is radially compressed between the collar and the ball pin when the parts are assembled will.

The leg of the collar which is in operative connection with the radial outer surface of the bulged end of the sealing cap stands, can be grooved or recessed on its inside to create an outer bulge at the bulged end take up, the annular collar on the sealing cap by joining the said groove or recess and the said Spread is kept. ...

The! Inflation is now based on them for example Illustrated reproducing drawing, namely Pig »1 shows a partially sectioned side view of a ball-and-socket joint with a sealing cap according to the innovation, while

^ igο 2 reproduces part of Fig. 1 with a modification.

In Fig. 1, the socket of the ball joint connection is at 10 shown, and the ball pin of the connection, which carries a head piece (not shown) that can be rotated and tilted or is pivotably mounted in bearings of the pan 10 is shown at 11. The pan 10 is threaded Shank 12 for fastening to a connecting bolt or another component of a vehicle control linkage in one piece manufactured, and the ball stud is tapered at 13 to fit into a tapered hole in another component 14 of said Rod to be included, which is held on the bolt by a nut 15. Of course, both can the socket and the ball pin, with other fastening means on components of a control linkage, a suspension device or the like are attached.

The sealing cap 16 for the ball joint connection has a sleeve made of elastic material, one end 18 of which has a smaller diameter than the other end 19, and. which has an intermediate section 21 which in diameter bigger than the bigger end. Said larger end 19 is provided with an outer groove 22 to a circumferential clamp or -clasp 23, by means of which it is clamped around the socket 10 with a ball-and-socket joint, the socket

is provided with a circumferential groove 24 around said end the cap. The smaller end 18 of the sealing cap is provided with a circumferential bead 25 of substantially D-shaped cross-section, the radial inner surface 26 of the Bead is flat and the radial outer surface 27 is rounded.

The wall of the sealing cap is connected to the bead 25 in such a position that the bead both inwardly and inwardly protrudes outside of the connection. The face 26 of the bead sits on a cylindrical surface on the ball stud.

An annular collar 28 of essentially L-shaped cross-section and made of metal, thermoplastic material or another material which is essentially inflexible is assembled with the sealing cap 16 in such a way that one leg 29 of the same surrounds the bead 25 and the other leg 31 where the cup 10 remote end face of the annular bead bears _s wherein said leg is provided with an internal circumferential groove 32 29 to the rounded external surface to take 27 of the bead, and the legs 31 extending inwardly in sighting the Kugelbölzen 11 and has a shallow play relative to this that the collar is freely rotatable on the ball pin ο

The radial thickness or layer thickness of the bead 25 and the inner radius of the leg 29 of the collar 28 are shown in FIG

With respect to the diameter of the cylindrical surface of the ball stud selected so that the bead 25 is pressed together radially between the annular collar and the stud and in this way is held in a firm operative connection with the stud surface. Since the collar 28 is held against noticeable transverse movement relative to the ball pin 11, the pressure on the cap as a result of the pivoting movement of the ball pin 11 relative to the socket 10 cannot pull the collar from the ball pin surface , Avif this way the pressure of the bead 25 is applied to the ball pin surface held constant despite the pivoting movement of the ball stud, and this pressure may be less than that which would be required if the tensile loads were able to pull the bead away from the ball stud.

If so desired, the end 18 of the sealing cap 16, which is in operative connection with the ball pin 11 stands like in Pig. 2 is shown against axial movement relative to the ball pin by a circumferential rib 33 on the ball pin are held, which protrudes between the radial leg of the Hingbundes 28 and the bead 25 on the sealing cap. .

Instead of having a D-shaped cross-section, the bead 25 can be essentially circular, as shown in FIG. or any other shape that has a sealing surface

or lip in contact with the ball stud and forms an outer contour which is self-fixing in the Ring collar 28 guaranteed.

The "inflation" also applies to amendments to the enclosed Protection claim 1 outlined embodiment and relates above all on all control notes, which are disclosed individually - or in combination - throughout the description and drawing.
