Definitions

  • the present invention pertains to a ball and socket joint protective cap for covering the pin-shaped partial area of a completely mounted ball and socket joint for the period from the manufacture to the installation of the ball and socket joint, the ball and socket joint being provided with a joint housing and a pivot pin accommodated pivotably therein.
  • Ball and socket joints in which the ball and socket joint protective cap of this type is used usually comprise a joint housing and a pivot pin accommodated within the joint housing by means of a bearing shell.
  • the pivot pin comprises a spherical bearing surface as well as a pin-shaped partial area, which extends at it in the axial longitudinal direction of the pivot pin and protrudes from the joint housing in the completely mounted state of the ball and socket joint.
  • a conical receiving section for fixing the ball and socket joint at another component for example, a chassis-side component of a motor vehicle, as well as a threaded section, which is usually provided for fixing and is provided with external threads, are usually present on this pin-shaped partial area.
  • sealing bellows Another component of such ball and socket joints is a sealing bellows, which seals the gap between the housing and the pivot pin protruding from an opening of the housing.
  • the sealing bellows is usually fixed statically at the housing and is arranged on the conical receiving section of the pivot pin displaceably in the axial longitudinal direction of the pivot pin and extending around same.
  • Usual ball and socket joint protective caps have at least two adjacent sections of different geometries, the section with the larger external dimension being attached to the housing of the ball and socket joint to be protected, adjacent to the edge area of the opening for the pivot pin.
  • the transition area between the individual sections may have a conical design in order to guarantee a sufficient distance from the components of the ball and socket joint that are to be protected.
  • the outer end of the ball and socket joint protective cap is closed by a cap-like section, so that a closed interior space is obtained for the protection of the pin-side partial area and of the sealing bellows after the ball and socket joint protective cap has been attached to the joint housing.
  • the object of the present invention is therefore to provide a ball and socket joint protective cap of the type of this class, which guarantees reliable protection of both the sealing bellows against the action of external forces and an additional protection of the gap between the pin part and the housing against dirt.
  • a ball and socket joint protective cap for covering the pin-shaped partial area of a completely mounted ball and socket joint, which is provided with a joint housing and a pivot pin accommodated pivotably therein.
  • the protective cap is attached to the pivot pin of the ball and socket joint with at least two sections of different geometries, which are arranged adjacent in the axial longitudinal direction of the ball and socket joint protective cap.
  • the section with the larger outer dimension is arranged at the end of the ball and socket joint protective cap, which said end faces the joint housing.
  • a transition area extends essentially at right angles to the axial longitudinal direction of the ball and socket joint protective cap. The transition area is arranged at the transition of the sections.
  • the displaceable sealing bellows located on the pivot pin is displaced due to this design embodiment in the direction of the joint housing due to the transition area extending at right angles to the axial longitudinal direction when the ball and socket joint protective cap is attached to the pin-shaped partial area of the ball and socket joint; this displacement leads to a deformation of the sealing bellows, as a result of which the sealing bellows becomes axially pretensioned and, as a result of this, the pressing forces increase as a consequence of the radial pretension of this component at the pivot pins of the ball and socket joint. This result guarantees an increased sealing action and prevents contaminants of any kind from penetrating into the interior of the ball and socket joint.
  • an additional sealing surface is created due to the fact that the transition area of the ball and socket joint protective cap extending at right angles to the axial direction is in contact with the outer edge of the sealing bellows, so that the outer area of the sealing bellows is also protected from contaminants as long as the ball and socket joint protective cap is attached to the ball and socket joint if the protective cap of the ball and socket joint is at the same time in contact with the housing.
  • Another embodiment of the present invention can be seen in the fact that three hollow cylindrical sections of different diameters are provided over the overall axial length of the ball and socket joint protective cap, wherein the diameter values of the individual sections decrease from the end to be attached to the housing to the opposite free end of the ball and socket joint protective cap, and a transition area extending essentially at right angles to the axial longitudinal direction of the ball and socket joint protective cap is arranged in the transition area of the hollow cylindrical sections.
  • an additional step which can bring about an additional sealing action in conjunction with the ball and socket joint to be protected, is thus created at the ball and socket joint protective cap in addition to the technical teaching described in claim 1 .
  • At least one radially inwardly projecting elastic tongue which may be designed as a tongue extending circularly over the entire inner contour if necessary, is arranged at the inner contour of the hollow cylindrical section located at the free end of the ball and socket joint protective cap, which said free end faces away from the joint housing.
  • This tongue engages a thread of the threaded section of the pivot pin enclosed by the hollow cylindrical section in question and thus ensures a reliable fixation of the ball and socket joint protective cap on the pin-shaped partial area of the pivot pin, and fixation of the ball and socket joint protective cap at the housing can thus be dispensed with.
  • An increase in the elasticity of the circular tongue can be brought about as an additional expedient embodiment by the radially inwardly projecting elastic tongue having a plurality of slots distributed over the entire circumference of the tongue.
  • the pulling off of the ball and socket joint protective cap is facilitated in that at least one radially outwardly projecting step, which may extend circularly, is arranged at the outer edge of the hollow cylindrical section located at the free end of the ball and socket joint protective cap, which said free end faces away from the joint housing.
  • FIG. 1 is a sectional view of a conventional ball and socket joint with a ball and socket joint protective cap according to the present invention attached to it;
  • FIG. 2 is a sectional view of the ball and socket joint protective cap alone.
  • FIG. 3 is a top view of the ball and socket joint protective cap corresponding to arrow B from FIG. 2 .
  • the ball and socket joint shown in FIG. 1 is formed essentially from a joint housing 1 , a bearing shell 2 located in an inner cavity of the joint housing, a pivot pin 3 accommodated within the bearing shell, a closing ring 4 as well as a sealing bellows 5 .
  • the pivot pin 3 has a ball head 6 as well as a pin-shaped partial area 7 , wherein the pin-shaped partial area 7 is in turn divided into a conical receiving section 8 as well as a threaded section 9 .
  • the ball and socket joint is provided with a ball and socket joint protective cap 11 for this purpose.
  • This ball and socket joint protective cap 11 has three hollow cylindrical sections 12 , 13 and 14 in the exemplary embodiment being shown.
  • the hollow cylindrical sections have different diameters, the hollow cylindrical section 12 with the largest diameter facing the joint housing 1 of the ball and socket joint.
  • the hollow cylindrical section 13 which is adjacent to the section 12 , has a slightly larger diameter than the conical receiving section 8 of the pivot pin 3 , which said receiving section is located inside and is covered by the section 12 of the ball and socket joint protective cap 11 .
  • a transition area 16 extending essentially at right angles to the axial longitudinal direction of the ball and socket joint protective cap 11 is arranged in the transition between the hollow cylindrical sections 12 and 13 .
  • This transition area creates a contact surface 17 on the inner side of the ball and socket joint protective cap 11 , which said contact surface 17 comes into contact with a corresponding contact surface 18 of the sealing bellows 5 when the ball and socket joint protective cap 11 is attached to the joint housing 1 and displaces the sealing bellows 5 in the direction of the arrows P. i.e., in the direction of the joint housing 1 on the conical receiving section 8 of the pivot pin 3 because of the dimensioning of the lengths of the individual hollow cylindrical sections.
  • the radial pretension is also increased at the contact surface with the pin-shaped area 7 and the sealing action is thus improved because of the deformation of the sealing bellows at its internal diameter that is in contact with the conical receiving section 8 as well as of the arched area 19 as a consequence of the axial pretension.
  • a sealing gap which protects the outer side of the sealing bellows 5 from contaminants, is created at the same time due to the contact between the contact surface 17 and the contact surface 18 .
  • the ball and socket joint protective cap according to the present invention is also provided in this exemplary embodiment with a transition area 20 extending essentially at right angles to the axial longitudinal direction of the ball and socket joint protective cap 11 in the transition between the hollow cylindrical section 13 and the hollow cylindrical section 14 .
  • the transition area 20 which is thus shaped as a step, comes into contact with a recess 21 of the pivot pin 3 , which is present between the conical receiving section 8 and the threaded section 9 .
  • the contact in the area of the recess 21 of the pivot pin 3 and the ball and socket joint protective cap 11 brings about an additional sealing gap, by which contaminants are prevented from penetrating into the cavity 22 between the hollow cylindrical section 13 and the conical receiving section 8 of the pivot pin 3 .
  • the prerequisite for contact with the recess 21 is that the diameter of the hollow cylindrical section 14 at the free end of the ball and socket joint protective cap be selected to be only slightly larger than the external diameter of the threaded section 9 .
  • FIG. 2 shows that to fix the ball and socket joint protective cap 11 on the pin-shaped partial area 7 of the pivot pin 3 , at least one radially inwardly projecting elastic tongue 24 , which is designed as a tongue extending circularly along the entire inner contour, is arranged at the inner contour of the hollow cylindrical section 14 located at the free end of the ball and socket joint protective cap 11 , which said free end faces away from the joint housing 3 .
  • at least one radially inwardly projecting elastic tongue 24 which is designed as a tongue extending circularly along the entire inner contour, is arranged at the inner contour of the hollow cylindrical section 14 located at the free end of the ball and socket joint protective cap 11 , which said free end faces away from the joint housing 3 .
  • this tongue engages a thread of the threaded section 9 of the pivot pin 3 , which said threaded section is enclosed by the hollow cylindrical section 14 in question and thus ensures the reliable fixation of the ball and socket joint protective cap 11 on the pin-shaped partial area 7 of the pivot pin 3 , so that fixation of the ball and socket joint protective cap 111 at the joint housing 1 can be dispensed with.
  • an increase in the elasticity of the circular tongue 24 can be brought about in such a way that the elastic tongue 24 , which is designed as an inwardly projecting circular tongue, has a plurality of slots 26 distributed over the entire circumference of the tongue, as this is clearly apparent from FIG. 3 .
