摘要： 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： 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 hot forming and of cold calibration, 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 piston for an internal combustion engine has an upper and a lower piston part. The upper piston part has a cooling cavity on its underside, and the lower piston part has a ceiling element with a cover hood, which closes off the cooling cavity. The cover hood is securely attached on the ceiling element if the central part of the cover element has an oil drain opening, the top of which is formed as a neck, the upper edge of which neck has a circumferential bead having an underside configured as a circumferential undercut, and if the cover hood has a centrally located opening, the edge of which has slits that are distributed over the circumference and lie radially. The cover hood is attached on the neck so that the sheet-metal tabs are snapped in below the undercut, between the slits, and form a secure snap-in connection with the neck.

摘要： A multi-part piston for an internal combustion engine has an upper piston part having a piston crown, and a lower piston part having pin boss supports and pin bosses connected with them. The upper piston part and lower piston part each have an inner and an outer support element, which delimit an outer circumferential cooling channel. The inner support elements delimit a cavity that is open toward the pin bosses, and the cavity is provided with a separate cooling oil collector that has at least one cooling oil opening. In a method for producing a piston, the upper and lower piston parts are manufactured, the cooling oil collector is inserted into one of the upper and lower piston parts in a region of the cavity, and the upper and lower piston parts are connected together at their support elements.

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： A piston for an internal combustion engine has a piston crown and a cooling channel disposed close to the piston crown and radially on the outside. The cooling channel is delimited on the underside by ribs uniformly distributed over the circumference, with openings lying between them. The openings of the cooling channel are closed off with two metal cover sheets attached to its underside, in the shape of a half circle. There is at least one oil inflow opening and at least one oil outflow opening in or between the cover sheets.
