  • the effective for transmitting power inclined contact surface of the pin to the conical disk is very small, also results in the transition between the conical journal portion to the axial portion of the pin weakening, especially when bending stress occurs.
  • the invention has for its object to achieve an improvement of the holder of the pin in the receiving opening.
  • the pivot pin remains free in the power transmission area of a weak point and no pressing a sleeve must be performed in the receiving opening.
  • the surrounding support is therefore only minimally stressed and can be made very thin and made of relatively soft and lightweight material, for example, a light metal casting.
  • the ring body does not have to be pressed onto the pin.
  • the tapered portion may have a pitch angle with respect to the axis of the pin of 15 ° to 20 ° at least in part of its axial extent and thus also allow a high axial preload.
  • a pressing of the ring body on the pin or an intimate, self-locking connection is still possible if the tapered portion is stepped and formed at its end remote from the pin end an axially parallel, cylindrical portion or portion of lesser pitch.
  • the region of the journal supported on the annular body, in particular a conical disk can nevertheless carry out a maximum force transmission to the conical disk without being influenced.

  • the tapered region has a variable pitch which reduces towards the end of the pin, a particularly good support against bending stress can be ensured with a simultaneous high axial prestressing.
  • the slope can go without a kink in a subsequent end of the pin and, for example, parallel-walled, cylindrical area.
  • annular body consists of a material of approximately the same strength as the pivot pin, the risk of plastic deformation of one of the two parts is reliably prevented.
  • the acting forces and tensions can be distributed evenly between them.
  • Such joint or bearing arrangements can be subjected to the axial prestress both axially and because of the large area support intense bending.
  • the pin can have a thread at the end of the pin and can be prestressed defined by a corresponding nut.
  • a joint arrangement according to the invention is therefore also used on highly loaded yet weight-optimized brackets of firmer parts in receiving openings softer parts, for example within chassis and / or steering parts of motor vehicles, such as in the support of parts of the suspension.

  • the wishbone 7 consists for example of a relatively soft aluminum, magnesium or cast iron or Schmieden material and may have around the opening 6 only a small amount of material, for example, in a thickness of only two to five millimeters, so as to extent and weight of To keep assembly as low as possible.
  • Such a joint arrangement 1, 101, 201, 301, 401 can be pressed in axially with a press fit.
  • the joint can be manufactured with diameter tolerances in the range of a few hundredths of a millimeter, as well as the internal dimension of the opening 6 of the female body 7.
  • the joint body 2 For its firm support in the opening 6 of the particular chassis or steering part 7 of the joint body 2 according to FIG. 1 comprises at least one in the direction of the condyle 3 opposite pin end 9 tapered section 8. About this, the joint body 2 is indirectly opposite the opening. 6 supported. Since the joint body 2 can be formed considerably harder with respect to the material surrounding the opening 6, for example made of a chromium molybdenum steel, this and the opening 6 an intermediate or closed annular body 10, in particular a conical disk, interposed, both with the edge of the opening 6 and with the tapered portion 8 is in contact.

In both cases, the supported conical region 8 is only in contact with the inner walls of the opening 6 via the conical disk 10, 10a.
  • a narrower and at least partially parallel and thus cylindrical or weaker tapering region 11 can adjoin the end 17 of the tapering section 8, which has a sufficiently small diameter to pass through the opening 6 even at its narrowest point and into to be able to open a thread 12 for cooperation with a nut 13 or other clamping element.
  • the pin 2 can be axially biased.
  • Such a joint and / or bearing arrangement 1 can counteract both radial loads, for example in guide joints, as well as axial and radial loads, for example in support joints.
  • a transition 14 between the tapered portion 8 supported on the ring body and the thinner portion 11 adjoining the pin end 9 is located outside the axial extent of the ring body 10 in the direction of the pin end 9.
  • the ring body 10 on its inner side can be in complete contact with the tapered section 8, resulting in a large force introduction surface which is not weakened by a bend or similar transition 14, since this transition 14 is outside the Contact surface between the annular body 10 and supported tapered portion 8 of the pin 2 is located.
  • the joint arrangement 401 according to FIG. 8 it becomes clear that at the transition 14 from the supported area 8 to the narrower area 11 of the pin 402 there may also be a greater pitch, so that the area 11 does not have to taper slightly overall than the supported area 8.
  • the supported in the mounted position on the annular body 10 and tapered region 8 has in a part 8a, which occupies the entire axial extent of the region 8 in the first embodiment of Figure 1 and Figure 2, a uniform pitch angle here relative to the axis 15 of the pin 2 of 15 ° to 20 °.

  • the annular body 10 can be pressed onto the region 8b.
  • a gradation 16 on the side facing away from the pin end 9 of the area 8 is harmless for the support of the pin end 9 facing region 8a.
  • the tapering region 8 can also have a variable incline, as shown in FIG. 6, which reduces the end of the spigot 9, or a pitch according to FIG. 7 which increases the spigot end 9.
  • the pin 302 of the joint or bearing assembly 301 is provided with a convex portion 8, correspondingly, the inner wall of the ring body 310 is formed concave in adaptation thereto.
  • a sufficiently large pitch must be present in order to achieve an axial biasing on the clamping element 13 can.
  • the shape of the section 8 can therefore be formed both overall hyperbolic and parabolic, with or without gradations, or in other ways, in each case a pin end-side transition 14 to the other, narrower portion 11 outside the support area 8 on the ring body 10, 110, 210, 310 is located.

Abstract

L'invention concerne un ensemble articulation et/ou palier (1 ; 101 ; 201 ; 301 ; 401) comprenant un corps d'articulation ou de palier pourvu d'un pivot (2 ; 102 ; 202 ; 302 ; 402). Ce corps peut être maintenu de manière fixe dans une ouverture de réception (6), par exemple dans une ouverture d'insertion d'un bras de suspension (7), et comporte, à cet effet, au moins une section (8) qui diminue en direction de l'extrémité (9) du pivot, et qui est conçue pour reposer au moins partiellement contre un corps annulaire (10 ; 10a ; 110 ; 210 ; 310), en particulier un disque conique auquel est reliée une zone (11) qui présente des parois parallèles ou qui diminue légèrement, en direction de l'extrémité (9) du pivot. Cette invention est caractérisée en ce que le passage (14) entre la section qui diminue et repose contre le corps annulaire (10 ; 10a ; 110 ; 210 ; 310), et la section (11) qui diminue faiblement en direction de l'extrémité (9) du pivot ou qui est cylindrique se situe en dehors de l'extension axiale du corps annulaire (10 ; 10a ; 110 ; 210 ; 310).
