Abstract
A piston in particular, a gallery cooled piston, of an internal combustion engine, includes at least one bottom part and at least one top part wherein the at least two piston parts have geometries which correspond in a connecting region in order to bring about a positively locking connection. A method for producing such a piston.
Claims10
A piston for an internal combustion engine comprising at least one lower part and at least one upper part, characterized in that the at least two piston parts have matching geometries in a connecting area to effect a positive-locking joint.
A method for producing a positive-locking connection between a lower part and an upper part of a piston, for an internal combustion engine, characterized in producing the positive-locking connection in one procedural step using a joining device.
The method from, wherein:
- creating an inseparable positive locking connection between the at least one lower part and the at least upper part of a piston by hot forming.
