Definitions

  • the invention relates to a joint and / or bearing assembly according to the preamble of claim 1 and of claim 12 and a motor vehicle with one or more such joint and / or bearing assembly (s), in particular in suspension and / or steering parts.
  • DE 44 03 584 C2 shows a ball joint for example, the use in steering or chassis areas of motor vehicles, in which the ball joint has a through hole, placed with this on a trunnion and secured by a flanged edge of the spigot end against deduction. An anti-rotation of the parts against each other is thereby by a
  • the invention is based on the problem, in particular to be able to provide joints with a good and environmentally friendly corrosion protection with simple and reliable installation.
  • the joint shell If beyond the axial extent of the pin and condyle and in the drawings above space outside these parts is limited only by the joint shell, this can be made as a cheap complete component, such as a one-piece injection molded part with a uniform inner radius. Alternatively, a substantially annular joint shell would be possible, which would then be included in a space-limiting bracket.
  • the one or more equalization channel or compensation channels can or can be used advantageously both for air passage and for the supply of lubricant. This also makes it possible to use very low-flowable greases which do not completely pass through the compensation channels even during long-term operation and thus remain available for the mechanically loaded space between the condyle and the socket.
  • the condyle consists of a surface-treated steel, in particular treated in a nitriding process, a good corrosion protection is ensured.
  • the assembly is easily possible if not an anti-rotation is provided, which would deform by the harder condyle, but when the condyle is held in a press fit on unstructured, round cylindrical surface portions of the pin without further assurance.
  • the surface portions may be interrupted by one or more, for example, four, even very thin compensation channels with, for example, each less than a millimeter radius.
  • the pin consists of a material deviating from the condyle, for example a tempering steel without further surface treatment.
  • An assignment of the compensation channel or the channels to the pin ensures that the frictional in operation against the joint shell and therefore mechanically loaded condyle is not weakened.
  • a plurality of compensation channels may be excluded as grooves from the peripheral surface of the pin.
  • An axial incorporation of the grooves is also possible in a journal production in F thoughpreßVM without machining post-processing.
  • channels in the condyle or the joint shell are possible depending on the requirements, which however means a weakening of the actual articular surface when using plastic chalen.
  • Such a joint can be used both on rotation about the journal axis in the manner of a bearing and on bending claimable and thus versatile and tolerance-compensating, for example within chassis and / or steering parts of motor vehicles, for example for supporting push rods and push rods connect a respective strut with a transverse to the vehicle torsion bar, as is required for the so-called.
  • Mc Pherson axis Such a joint can be used both on rotation about the journal axis in the manner of a bearing and on bending claimable and thus versatile and tolerance-compensating, for example within chassis and / or steering parts of motor vehicles, for example for supporting push rods and push rods connect a respective strut with a transverse to the vehicle torsion bar, as is required for the so-called.

  • FIG. 2 is a view similar to FIG. 1 but with only partially cut pin
  • FIG. 3 shows the pin drawn out of FIG. 1 with pressed-on condyle
  • FIG. 4 is a view similar to FIG. 3 but with only partially cut pin
  • FIG. 5 shows a section along the line VI-VI in Fig. 4th
  • the joint 1 which is completely illustrated in FIGS. 1 and 2, comprises a pin 2, onto which a joint head 4, here a joint ball, is pressed in a substantially round-cylindrical neck region 3.
  • the separate before his installation condyle 4 without machining is easy and inexpensive to produce and here has a flattened on two opposite surfaces spherical shape with a transverse to the flats through hole, with which he engages the pin 2 in the mounted position.
  • Other outer shapes of the condyle for example, a round cylindrical or a truncated cone shape are possible with appropriate requirements.
  • the condyle 4 can be subjected to a surface treatment, in order to better withstand the stresses in frictional contact with the surrounding joint shell 5 during continuous operation, and in particular to have a good corrosion resistance.
  • the harder joint head 4 is held in a press fit on round cylindrical surface portions 16 of the pin 2, wherein the pressure is sufficiently large that an additional assurance, such as a beading of the pin end, is completely unnecessary.
  • the journal 2 of the embodiment has for typical applications in chassis and steering range of motor vehicles in his condyle 4 holding neck portion 3 has a diameter of nine to about fifteen millimeters and can be widened, for example, conically in its the condyle 4 facing away shoulder region 6 to increase the stability ,
  • joint head 4 In the assembled state of the parts of the joint head 4 is held immovably in the press fit on the neck portion 3 of the pin 2 and with respect to a surrounding joint shell 5, which may consist of a weight and cost minimization of plastic, movable, wherein the movement both a deflection in the direction of Arrows 7 or 8 as well as a rotation about the axis 9 of the pin 2 may be. Therefore, such a joint arrangement can also act in the manner of a bearing and is also generally referred to as a joint and / or bearing assembly.
  • the joint shell 5 is bordered by a steel ring 10 for stabilization and for connection to other parts, for example, links, pull and / or push rods or the like.
  • the joint 1 is encompassed by a total of a seal 11, so that the pin 2 outside an accessible attachment end 12, for example a screw head, from the outside is not accessible and lubricant can not escape.
  • a substantially annular joint shell possible, which would then be recorded, for example, in a not only annular support (steel ring 10), but in a space 13 outside the axial extent of the pin 2 and the condyle 4 completely limiting support.
  • the space 13 between the joint head 4 and the joint shell 5 is at least partially filled with a lubricant, which serves to reduce friction between the contact surfaces of condyle 4 and joint shell 5.
  • the lubrication can be provided in particular for the entire projected life of the joint 1. In this case, a tough and low flowable lubricant is used.
  • the located between the joint head 4 and this surrounding joint shell 5 space 13 is according to the invention with a respect to the axial extent of the pin 2 beyond the condyle 4 located space 14 via one or - as shown here - several equalization channels 15 connected.
  • four similar and over the outer circumference of the neck region 3 evenly distributed compensation channels 15 are provided for connecting the spaces 13 and 14. They are recessed as grooves from the peripheral surface of the pin 2 in its neck region 3 and each extend axially rectilinear with a radius of slightly less than one millimeter here, with a total diameter of the neck region 3 of about nine millimeters. Another, such as a spiral or wavy, course is possible.
  • Channels 15 - depending on the viscosity of the lubricant and the cross-sectional area of the respective channel 15 - variable.
  • the channels 15 can receive an excess of lubricant and / or a during assembly between shell. 5 and condyle 4 derived excess pressure in the room 14 derived. Due to the low fluidity of the grease ensures that this is not readily passes through the channels 15 and is transferred into the space 14.
  • an axial central bore in the pin 2 with outwardly transversely in the space 14 leading channels would be possible.
  • one or more channels associated with the condyle 4. In general, however, this is highly loaded in a small space, so that a material weakening in the pin 2 is more advantageous than the condyle 4. In any case, damage to the thin-walled joint shell 5 during assembly or in subsequent operation, for example, in temperature increase, by overpressure of lubricant or air through the at least one compensation channel 15 is prevented.
  • the neck region 3 has a completely round-cylindrical outer circumference 16, as is visible, for example, in the cross-sectional view according to FIG. 5.
  • the joint head 4 can therefore, as already indicated above, be held on the unstructured surface portions 16 between the grooves 15 in a press fit without a profiling would be required there.
  • a relative to the pin 2 significantly harder condyle 4 can be mounted.
  • grooves 15, as shown here, extend axially through the pin 2 into the transition region from the parallel-walled neck region 3 to the conically widening shoulder region 6, an increase in stability of the pin 2 at a bending stress results around its Axis 9 against a made without grooves 15 and otherwise the same pin, as can be demonstrated by FEM calculations.
  • the improvement in the materials and dimensions given here is on the order of almost ten percent.
