摘要： A piston for an internal combustion engine has an upper piston part and a lower piston part, which form an outer circumferential cooling channel. The piston has pin boss connections that lie opposite one another, at which pin bosses are provided, which have pin bores that define a center axis (M). The upper piston part and the lower piston part are connected with one another by way of outer joining surfaces and inner joining surfaces. A bridge that runs essentially parallel to the center axis (M) is configured in the lower piston part, in the region of the pin boss connections. The bridge has two longitudinal sides that delimit an upper bridge surface.

摘要： What is proposed is a method for the production of a piston (1) made of steel, for an internal combustion engine, in which the upper piston part (3) is produced using the forging method, and the lower piston part (4) is produced using the forging or casting method, and they are subsequently welded to one another. To simplify the production method and make it cheaper, the upper piston part is forged using the method of semi-hot forming, to finish it to such an extent that further processing of the combustion bowl and of the upper cooling channel regions can be eliminated.

摘要： A method for attaching a ring element to a piston for an internal combustion engine, in which the ring element is screwed onto the piston body by a thread applied to the radially outer surface of a part of the piston crown, a circumferential groove that is open towards the top is formed into the piston crown in the region of the thread, the groove is filled with solder material, the piston is heated until the solder material liquefies and flows between the thread channels of the thread and subsequently, the piston is cooled. As a result, a secure screw connection between the basic piston body and the ring element is obtained. Furthermore, the cooling channel is sealed with regard to the combustion gases, which stand under high pressure and act on the piston crown.
