Definitions
- the invention relates to a connecting rod bearing shell or bush in internal combustion engines or a main bearing shell for mounting the crankshaft in internal combustion engines, made of a plain bearing composite material with a metallic, in particular made of steel support layer and a metallic sliding layer applied thereon.
- connecting rod bearing elements namely connecting rod bearing shells enclosing the crank pin of a crankshaft and connecting rod bearing bushes enclosing the piston pin, which can be pressed into the small connecting rod bearing
- resistance is required for connecting rod bearing shells even at high sliding speeds and medium loads
- resistance is required for connecting rod bearing bushes under high loads and, in contrast, higher temperatures, but at low to moderate sliding speeds.
- main bearing shells for crankshafts are characterized by the lower load occurring there compared to connecting rod bearing shells and the high sliding speed at relatively moderate temperatures. Main bearing shells must also be able to compensate for misalignment of the crankshaft.
- connecting rod bearing bushes for use in the small connecting rod eye of an engine connecting rod, the sliding layer of which is made of a copper zinc alloy with a relatively high zinc content of approximately 30% by weight and with 2% by weight of manganese, 2% by weight of nickel, 2 wt .-% Aluminum and 1.8 wt .-% iron.
- DE 44 11 762 AI discloses a plain bearing composite material in which a copper-zinc wrought alloy with a high zinc content of 28 to 32% by weight is applied to a steel support layer by roll cladding.
- CH 223 580 discloses copper-zinc alloys, in particular for the production of machine parts subject to sliding loads with 2 to 8% by weight aluminum, 0.05 to 3% by weight silicon, 0.5 to 10% by weight manganese and 50 to 70% by weight copper. Up to 10% by weight of lead and 0.1 to 5.0% by weight of iron, nickel and cobalt can also be alloyed into the alloy.
- DE 197 28 777 C2 discloses a layered composite material with a carrier layer and a bearing metal layer, in particular made of a copper-zinc alloy and a galvanically applied lead-free sliding layer based on tin. Proceeding from this, the present invention seeks to provide a plain bearing composite material which is suitable both for use as a connecting rod bearing shell and for use as a connecting rod bearing bush and main bearing shell for the crankshaft.
- the sliding layer of the connecting rod bearing shell or connecting rod bearing bush or main bearing shell is formed from a copper-zinc alloy which contains 10-25% by weight of Zn, 1-3% by weight of Mn, 1-3% by weight. -% Ni and 2 - 6% by weight Fe, the rest copper and contamination-related components of a maximum of 0.1% by weight, in total up to max. 1 wt .-% and that the sliding layer is crystallized exclusively in the ⁇ -phase.
- Plain bearing material can be obtained, which is particularly suitable with regard to signs of corrosion.
- ß-brass tends to selective corrosion and acts as a sacrificial anode in the metallic connecting rod.
- the high iron content has a hardening effect and increases the toughness of the material; it leads to grain refinement and increases the recrystallization temperature of the alloy.
- the iron content is preferably 3.5 to 4.5% by weight.
- the sliding layer consists of the above-mentioned components or consists of an alloy which additionally has 1-3% by weight of aluminum. Aluminum increases the strength of the alloy according to the invention somewhat.
- a thin overlay layer facing the sliding partner is formed on the sliding layer, which is a galvanically applied tin layer or a tin layer with PTFE inclusions or a layer of aluminum sputtered onto a diffusion barrier layer -Tin alloy. If the overlay layer is to serve as a running layer, layer thicknesses of more than 10 ⁇ m are selected, and if it is only to serve as a running-in layer, layer thicknesses of ⁇ 5 ⁇ m are selected.
- a preferred composition of the sliding layer of the connecting rod bearing shell or connecting rod bearing bush according to the invention comprises, in percentage by weight composition, Cu (remainder) Zn (19-21) Mn (1.5-2.5) Ni (1.5-2.5) Fe (3.5- 4,5) Al (1,5-2,5) and particularly preferably the sliding layer is a CuZn20Mn2Ni2Fe4Al2 alloy.
