Definitions
- the invention relates to a bearing block for a crankshaft Internal combustion engine, especially in a row or V arrangement.
- combustion results in a known manner Gas power. Between the crankshaft or its bearing and cylinder head, the Gas power can be absorbed. This acts on the crankshaft via the pistons and the connecting rods and unfolds power components on the crankshaft that both can be directed downwards as well as sideways.
- the safe and permanent Inclusion of these gas forces is a determining factor in the efficiency of the Internal combustion engine and its durability.
- One way to optimize is Use a bearing chair that is screwed against the cylinder block from below is and due to a suitable frame construction to stiffen the Internal combustion engine leads.
- DE 296 09 950 describes a bearing bracket for a crankshaft of an internal combustion engine known that is screwed against the cylinder block from below.
- the camp chair forms the lower half of the holes for the crankshaft bearings, while the upper Half is formed by the bearing cap, which is screwed onto the bearing bracket become.
- the bearing caps are on the side facing the cylinder block screwed to the storage chair.
- the bearing cover is outside the assembly area a sealing surface for mounting the bearing block on the internal combustion engine or the cylinder block provided.
- crankshaft bearing cover with the cylinder block outer surfaces to screw to the system rigidity and the resulting lateral gas forces to be able to record better.
- This arrangement also serves the purpose of Gas forces on the crankshaft to vibrations transmitted to the bearing blocks to reduce.
- the Has bearing cap for the crankshaft on which bearing cap contact surfaces for Bearing chair are formed and on the side facing the cylinder block of the camp chair are attached, the camp chair providing a surface for assembly of the internal combustion engine, which surrounds the bearing cover provided according to the invention, the bearing cap contact surfaces compared to the To arrange the bearing cover surrounding area increased. This results in inevitably that between the bearing cap contact surfaces and the surrounding Surface a transition shoulder must be formed. This causes stiffening of the camp chair. In addition, this leads to the fact that the bearing cap at Production of the storage chair can be cast with.
- the bearing caps have bores for the cylinder block mounting screws so that the transition shoulder migrates outwards between the bearing cap contact surface and the surrounding surface and thus also the transition shoulder between the mentioned surface further outside lies.
- the surrounding surface of the Bearing chair formed as a sealing surface to the cylinder block.
- the sealing surface for In this configuration, the oil pan is on the underside of the bearing chair arranged.
- the Bearing bracket fastening screws carried out through the cylinder block and directly screwed to the cylinder head. This has the advantage that the cylinder block no longer under tension and pressure but only under pressure. In addition, separate cylinder head bolts are no longer required.
- Fig. 1 shows schematically a section through the middle of a Bearing cover attachment runs.
- the internal combustion engine 1 consists in a known manner of a bearing chair 2, the Cylinder block 3 and the cylinder head 4.Oil pan 7 and cylinder head cover 8 are also only shown schematically.
- Bearing caps 5 are on the bearing chair 2 screwed on by means of bearing cap fastening screws 51. Between camp chair 2 and the bearing caps 5 are the bores 52 for the crankshaft bearings (Main camp) provided. Approximately the lower half of the bearing bore 52 is in the Bearing chair while the top half is attached to the bearing cap. Between Bearing chair 2 and bearing cover 5, the bearing cover contact surfaces 53 are formed. These can be machined surfaces or - during the Production of the bearing chair 2 molded bearing caps 5 - around broken surfaces act.
- the bearing cap contact surfaces 53 are opposite the sealing surface 54 is raised, is located closer to the cylinder head 4 than the sealing surface 54, is inevitably a transition shoulder between bearing cover contact surfaces 53 and form sealing surface 54.
- the sealing surface 54 is preferred here shown embodiment up to the bore 9, 10 of the fastening screws 6 in Extending towards the crankshaft bearing bore 52 is the transition shoulder between the bearing cap contact surfaces 53 and the sealing surface 54 between the Bearing cap mounting screws 51 and the cylinder block mounting screws 6 arranged. This allows the transition shoulder on one or more of the Bearing cover 5 as a lateral guide approximately perpendicular to the sealing surface 54 between Bearing bracket 2 and cylinder block 3 are formed.
- the transition shoulder between the sealing surface 54 and bearing cap contact surface 53 also between the bore for the Cylinder block mounting screws 6 and bearing wall outer wall 55 are formed his.
- the transition shoulder between the Bearing cover contact surface 53 and sealing surface 54 formed fitting surfaces are preferred trained in alignment.
