摘要： Pin bosses of a piston for an internal combustion engine each have a pin bore for supporting a piston pin. In order to reduce the tangential stresses in the zenith area of the pin bores, and thus to extend the service life of the piston, the inner areas of the pin bores as viewed in the direction of the bore axis have areas on both sides of the zenith that have a greater distance from the bore axis than the zenith of the pin bore, and the outer areas of the pin bores, as viewed in the direction of the bore axis, are transversely oval relative to the piston axis.

摘要： The invention relates to pin bosses (1) of a piston (2) for an internal combustion engine, each comprising a pin bore (3) for supporting a piston pin (14). In order to reduce the tangential stresses in the zenith area of the pin bores and thus to extend the service life of the piston, the inner areas (16) of the pin bores (3) as viewed in the direction of the bore axis (13) have areas on both sides of the zenith (4) that have a greater distance from the bore axis (13) than the zenith (4) of the pin bore (3), and the outer areas (17) of the pin bores (3) as viewed in the direction of the bore axis (13) are transversely oval relative to the piston axis (7).

摘要： The invention relates to a piston (1), which is comprised of an approximately circular cylindrical upper area (5) and of a lower area (6), having two hubs (7), which are set back toward the piston central axis (8) so that, in the upper area (5), recesses (12, 12′) can be made, which are open toward the lower area (6), in the vicinity of the hubs (7). In order to make relief cuts (13, 13′) in the area between the hubs (7) and the upper area (5), a salt mold part (15) is placed on the respective window insert (14). The salt mold part (15) serves to produce the recesses (12, 12′) as well as the relief cuts (13, 13′) when casting the piston (1) and is washed out after the piston (1) has been cast.
