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