Beschreibung
Zusammenfassung:	The invention relates to a piston (10, 110, 210) for a combustion engine, having a piston main body (11, 111, 211) and a piston ring element (12, 112, 212), wherein the piston main body (11, 111, 211) has at least one inner region (14) of a piston crown (13) and a piston skirt (16) that is provided with pin hubs (18) having hub bores (17), wherein the piston ring element (12, 112, 212) has at least one outer region (21) of a piston crown (13) having a circumferential top land (22) and a circumferential ring part (23) provided with annular grooves (24). According to the invention the piston main body (11, 111, 121) and the piston ring element (12, 112, 212) are joined together by means of corresponding conical joint surfaces (32, 33, 27, 28; 135, 136; 232, 233, 227, 228) formed thereon. The invention further relates to a method for producing such a piston.
