摘要： The invention relates to an assembled piston (1) for an internal combustion engine, said piston consisting of an upper part (4) and a lower part (5) that are interconnected by means of an internal hexagon screw (6) consisting of an upper half (37) and lower half (38). The upper half (37) of the internal hexagon screw (6) comprises an external thread (39) which is parallel to the external thread (40) of the lower screw half (38) and has a larger lead angle than the same (40). The lead angle resulting from the difference between the lead angles of the two external threads (39, 40) is very small and contributes to a high strength of the screw connection.

摘要： A piston for an internal combustion engine has a piston head and a piston skirt spaced apart from the piston head by a ring-shaped recess. The piston has at least one pin bore for accommodating a piston pin. A ring-shaped circumferential cooling channel for a coolant is provided in the piston head, which channel is closed off by a cover ring that consists of at least two segments. At least one region of the cover ring projects at least partially into the clear opening of the at least one pin bore, in such a manner that the cover ring simultaneously forms the retaining element for the piston pin.

摘要： A multipart cooled piston for an internal combustion engine comprises an upper part and a lower part of the piston. The two parts are screwed together via a threaded bolt that is arranged on the upper part of the piston, and a threaded bore that is drilled into the lower part of the piston. The threaded bore is arranged in an area of the lower part of the piston that is thin-walled to such a degree that it is deformed like a plate spring as the two parts of the piston are screwed together, so that no other safety means such as a lock nut are required for securing the assembled piston.

摘要： A piston for an internal combustion engine has a piston head and a piston skirt. The piston head has a circumferential ring belt and a circumferential cooling channel. The piston skirt has a working surface assigned to its major thrust side and to its minor thrust side. A bore that proceeds from the cooling channel is provided, which ends in the working surface assigned to the major thrust side, and is disposed at an incline, in such a manner that the bore exit encloses an acute angle (α) with the center axis (M) of the piston. An opening is formed in the working surface, and a deflection surface inclined relative to the working surface is provided between the bore and the bore exit. The working surface assigned to the major thrust side has a depression which forms at least one oil capture region above the opening.

摘要： Proposed is a multi-part cooled piston (1) for an internal combustion engine, which piston (1) is composed of an upper piston part (2) and a lower piston part (6). The upper piston part (2) forms an inner annular cooling duct (11) with the lower piston part (6), which cooling duct (11) is covered by an upper region (31) of the lower piston part (6). The region (31) is of thin-walled design in such a way that it can be deformed in the manner of a plate spring. Simple and fast assembly of the upper piston part (2) on the lower piston part (6), and a fixed and secure screw connection between the two piston parts, result in that the upper piston part (2) is provided on its underside with a blind bore (26) which is arranged centrally and coaxially with respect to the piston axis (25) and has an internal thread (28), and in that the upper region (31) of the lower piston part (6) has a threaded bolt (29) which is arranged centrally and coaxially with respect to the piston axis (25), points upward and has an external thread (30), with the internal thread (28) matching the external thread (30), such that the upper piston part (2) can be screwed to the lower piston part (6) by means of the blind bore (26) and the threaded bolt.
