PIN BOSSES OF A PISTON FOR AN INTERNAL COMBUSTION ENGINE
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).
