Definitions
- the present invention relates to a connecting rod, which is provided with eyes at both ends, in which bearings for the crankshaft or for the articulation of the piston pin are arranged, and a method for their production.
- Connecting rods perform the task of connecting the pistons of the individual cylinders to the crankshaft in a drive motor, as a result of which the linear actuating movements of the pistons are converted into the rotational movement of the crankshaft.
- the connecting rods are formed at both ends with bearing eyes, by means of which they are articulated on the one hand on the piston and on the other hand on the crankshaft.
- bearing eyes There are slide bearings or roller bearings in the bearing eyes, which consist of a plurality of components such as support shells, bearing elements and the like.
- the objective of the present invention is therefore to create a connecting rod by which the disadvantages inherent in the known prior art are avoided.
- This is achieved according to the invention in that at least one of the two bearings is formed exclusively by coating and / or coating the inner surface of the bearing eye. Both bearings are preferably formed by a coating and / or a coating of the inner surfaces of the bearing eyes.
- the inner surface of at least one of the two bearing eyes can be oxidized, nitrided, borated, carbonized or thermochemically treated.
- the inner surface of at least one of the two bearing eyes can be coated with a copper alloy, an aluminum alloy, an aluminum-tin alloy, an aluminum-tin-zinc alloy, an iron alloy, a copper-lead Alloy, a copper-lead-tin alloy, a copper-lead-nickel alloy, a copper-zinc alloy, a copper-tin-zinc alloy, a copper-tin alloy, a copper-phosphorus Alloy, a copper-aluminum alloy, a copper-beryllium alloy, a lead-tin alloy, a tin alloy, a lead alloy, a molybdenum alloy, a metal hydrocarbon, a metal carbon , a thermoplastic or a thermoset, a diamond-like carbon, a steel or ceramic coated individually or in combination.
- the coating preferably contains a solid lubricant.
- the entire surface of the connecting rod or at least the contact surfaces are tempered and / or coated individually or in combination with one of the above materials.
- a method for producing such a connecting rod is characterized in that the coating of the inner surface of at least one of the two bearing eyes in a manner known per se by chemical vapor deposition (CVD), physical vapor deposition (PVD), plasma enhanced Chemical vapor deposition (PE-CVD), plasma enhanced-physical vapor deposition (PE-PVD), electroplating, sputtering, plasma spraying, flame spraying, plasma transferred arc are carried out.
- CVD chemical vapor deposition
- PVD physical vapor deposition
- PE-CVD plasma enhanced Chemical vapor deposition
- PE-PVD plasma enhanced-physical vapor deposition
- electroplating electroplating
- sputtering plasma spraying
- flame spraying flame spraying
- plasma transferred arc electroplating
- a connecting rod according to the invention is explained below with reference to an embodiment shown in the drawing. Show it:
- a connecting rod 1 according to the invention is formed at its two ends with two bearing eyes 2 and 3, which have different diameters, the bearing eye 2 with a smaller diameter for articulation on a piston of the engine and the bearing eye 3 with a larger diameter for articulation serves the crankshaft.
- the larger bearing eye 3 is formed with a bearing cover 32 which is fastened to the connecting rod 1 by means of screws 33.
- the inner surfaces of the bearing eyes 2 and 3 are coated and / or coated.
- the outermost layer can be designed as a running layer 11, to which an intermediate layer 12 and a sliding layer 13 adjoin which are applied to the base material 14 of the connecting rod 1.
- These layers achieve the necessary storage properties, such as good load-bearing capacity and good sliding properties.
- the connecting rod 1 can consist of a titanium alloy, a steel alloy, an aluminum alloy, metal matrix composites, metal plastic composites or ceramic. It is necessary for the coating to adhere well to the bearing surfaces, furthermore for good sliding properties or low coefficients of friction and also for good load-bearing capacity. In addition, the coatings must have low residual stresses.
- the coating can be achieved by chemical vapor deposition (CVD), physical vapor deposition (PVD), plasma-enhanced chemical vapor deposition (PE-CVD), plasma enhanced-physical vapor deposition (PE-PVD), electroplating, plasma spraying, flame spraying, plasma transferred arc or the like. er ⁇ follow, the materials being applied directly to the bearing surfaces.
- the surface finish can be oxidized. Nitriding, boronizing, carbonizing, thermochemical treatment or the like. respectively.
- a layer can be provided which has great strength and hardness, a very thin layer of a material with low hardness and with very good sliding and emergency running properties can be applied over it.
- several such layers with the different properties can be provided. The individual layers can be applied in different processes.
- the individual layers can consist of one or more materials from the following groups:
- the entire surface of the connecting rod is also preferred, or at least the contact surfaces are tempered or coated.
