Definitions
- the invention relates to a piston built according to the preamble of claim 1.
- the invention is therefore concerned with the problem of increasing the hub and support strength and the strength in the area of the screw connection in the case of generic pistons and at the same time keeping the weight of the piston low.
- the thrust pieces usually used in generic pistons for introducing force into the aluminum lower part can advantageously be dispensed with if, as shown in the exemplary embodiment, the force introduction of the connecting screws takes place in the iron material of the upper part and the hubs or the hub support or the connecting plates.
- the bolt hubs screwed to the lower part consist of steel, then preferably forged steel is used. Cast steel can also meet the requirements.
- Fig. 1 a piston according to the invention in
- Fig. 2 is a bottom view, cut at the level of the bolt axis.
- the screw shown at the top left is the Lichity not drawn in the correct position, but so that it is shown broken with its real pitch circle.
- a built-in piston 1 has a steel upper part 2 and a lower part 3 made of an aluminum-based material.
- pin bosses 4 made of an iron material, which were produced by casting or forging, are mounted with a connecting plate 5 integrally formed with four screws 6.
- the four screws 6 are introduced into the steel upper part 2 and into the connecting plate 5.
- the lower part 3 is clamped between the upper steel part 2 and the connecting plate 5. The correct positioning of the upper part 2 to the lower part 3 and the connecting plate 5 to the lower part 3 is ensured by dowel pins 7.
- connecting plates 5 there can be provided - as shown in FIG. 1 - a plate integral with the two hubs 4 as well as one for each hub, that is a total of two plates integral with the respective hubs.
- the connecting plate or plates facilitate precise positioning of the pin hubs relative to the piston center axis.
- the lower part 3 consists of a shaft 8 and a lower part base 9, which has a cooling oil opening 10 in its center towards a central cooling space 11.
