- Figure 1 shows a plan view of a connecting rod 1 in Korbhenkelbauweise.
- the connecting rod 1 has a large connecting rod eye 2 and a small connecting rod eye 4, which is connected via a connecting rod 6. are bound.
- small connecting rod 4 is formed a bushing receiving bore 8 for receiving a bearing bush.
- the piston rod side axial length of the small connecting rod 4 and the bushing receiving bore 8 is greater than the axial length in the region remote from the piston rod 6 (top in Figure 1).
- the piston rod-side peripheral region of the bushing receiving bore 8 is provided with the reference numeral 10 in FIG.
- the transition to the narrower, overhead peripheral portion 12 is rounded.
- step shape or a trapezoidal shape can be formed, through which the small connecting rod eye 4 is tapered in the illustration of FIG 1 upwards.
- Beech receiving bore 8 of the small connecting eye 1 is inserted.
- This has the basket handle shape described above.
- the bearing bush 14 is designed with a corresponding Axialinvariation, so that the bearing bush 14 is fully adapted to the inner circumferential wall contour of the bushing receiving bore.
- Figure 3 shows a highly schematic representation, in which the contours of the inner peripheral wall (inner cylinder 16) and the outer peripheral wall
- the part of the bearing bush 14 with a larger axial length is often saddle-shaped or convexly arched, so that the peripheral areas adjacent to the front edges are higher than the peripheral areas located therebetween.
- there is a so-called eraser effect wherein the higher lying areas are subjected to a larger friction and correspondingly greater wear. Lying in FIG. 3 at the bottom, the piston rod-side peripheral portion 10 of the bushing receiving bore 8 is drawn in a rectangular shape in a first approximation. The piston rod 6 is then correspondingly below.
- the bearing bush 14 with the then visible inner cylinder 16, wherein the bearing bush 14 is cut parallel to the plane, so that a cutting edge 20 of the inner cylinder 16 and the corresponding cutting edge 22 of the outer cylinder 18 is visible.
- the inner cylinder 16 When pressing in the bearing bushing 14 described above, the inner cylinder 16 then bulges inwards in the lateral areas 24, 26 of the bearing bush 14 which are adjacent to the end edges, into the connecting rod eye 4. The area lying between these vaulted areas 24, 26 is accordingly concave inwardly.
- the running surface of the bearing bush 14 is identified by the reference numeral 19.
- the outer cylinder 18 is arched, so that between this outer cylinder 18 and the inner peripheral wall of the indicated
- Socket receiving bore 8 cavities 28, 30 arise, so that the system of the bearing bush 14 to the peripheral wall of the bushing receiving bore 8 at least in the region of the peripheral portion 10 is not or only partially and thus the holding force and the bias for the bearing bush 14 is reduced.
- cavities 28, 30 are formed in the case of step-shaped or basket-shaped connecting rods, in particular on the rod side outside the closed annular cylinder section 21, that is to say in the regions of the circumferential section 10 which are elongated in the axial direction. Accordingly, the contact pattern of such a conventional
- this shape curve may be formed, for example, trumpet-shaped, so that the diameter D, as shown in Figure 4 right top strongly schematized, to the two end faces 32, 34 of the small connecting rod eye 4 extended.
- this shape curve may be formed, for example, trumpet-shaped, so that the diameter D, as shown in Figure 4 right top strongly schematized, to the two end faces 32, 34 of the small connecting rod eye 4 extended.
- Figures 3, 5 and 6 other shape curves can be selected. In principle, the interpretation is done so that the Wear pattern and the preload compared to the conventional solution is significantly improved.
- inventive design of the bushing receiving bore 8 is shown. It can be seen clearly that the inner circumferential surface of the inner cylinder 16 is formed substantially flat, cylindrical, without the above-described indentations are present. It can also be clearly seen that the outer cylinder 18 rests flat against the inner peripheral wall of the bushing receiving bore 8, in particular in the regions lying outside the dot-dash line closed annular cylinder section 21 of the bearing bush 8. The above-described cavities 28, 30 are almost completely eliminated or at least significantly reduced, so that the contact pattern and thus the holding force of the bearing bush 14 is improved over the conventional solutions without calibration. Of course, a calibration can be done in a subsequent operation.
- Figure 5 shows a diagram in which the Einpresshaltekraft F is shown on the receiving diameter D of the bushing receiving bore 8. It can be seen that even with decreasing receiving diameter, the Einpresshaltekraft F increases linearly - then there are no deformations on the inner cylinder 20 of the bearing bush 14 can be seen. Such a behavior is not feasible in a conventional concept with cylindrical bushing bore. As already explained at the beginning, the test can be done as described above
- Cavities are present or not, for example, tomographically, wherein a measuring machine can be used or can also find a handset with a special probe use. Of course, other measuring methods for detecting any existing cavities can be used.
- the bush receiving bore 8 is formed with a trumpet-shaped in the axial direction variable diameter.
- Figure 6 shows a variant with a radially variable bushing receiving bore (mold bore) 8 in the small connecting rod 4.
- the peripheral surface is designed approximately as a 3-leaf clover.
- the bushing receiving bore 8 is widened approximately kidney-shaped in three regions distributed around the circumference, so that a kind of trefoil structure is formed in the represented cross-section.
- Such a profile bore profile gives the small connecting rod eye a particular torsional stability.
- This shape can theoretically also be formed trumpet-shaped in the axial direction, in which case a circular cross-section can be formed in the middle region.
- This central, circular region is identified by the reference numeral 38.
- the cylindrical bushing receiving bore 8 known from the prior art is shown, in such a cylindrical bushing receiving bore the diameter U1 is constant over the axial length Z.
- Profiles according to the invention are preferred, as shown in FIG. 7 under 2), 3) and 4).
- This profile preferably remains constant over the entire axial length Z, but may also vary as indicated.
