摘要： A piston for diesel engines is made of a toughness-increasing aluminium alloy containing copper, nickel, silicon, magnesium, iron and manganese. The use of this material, which can conventionally be chill-cast, and by implying special dimensions, provides a piston which, despite its relatively light construction, provides the utmost security against cracking in the stressed regions, e.g. the piston boss or the combustion chamber recess.

摘要： The invention relates to a piston, particularly of light metal, for internal combustion engines, comprising a piston skirt substantially closed in the peripheral direction, pin bosses set back with respect to the piston skirt diameter in the direction of the piston axis, and two supporting skirt wall sections which thus remain on the piston skirt on the thrust and the counter-thrust side. The supporting skirt wall section on the thrust side is larger at least in the peripheral direction of the skirt than the supporting skirt wall section on the counter-thrust side.In order to divert the lateral forces acting on the supporting surfaces to the entire supporting structure in an elastically cushioned but safe manner, the two wall sections of the skirt connecting the supporting wall sections are respectively continuously curved convexly outwards as seen along the periphery of the piston skirt at least at the open skirt end beneath the pin bosses. The cross-sectional configuration of the piston skirt can therefore be described as being "egg-shaped".
摘要翻译：本发明涉及一种用于内燃机的活塞，特别是涉及轻金属的活塞，其包括在周向方向上基本上封闭的活塞裙部，相对于沿着活塞轴线方向的活塞裙部直径设置的销凸起，以及两个支撑裙壁部分因此在推力和反推力侧保留在活塞裙部上。在推力侧的支撑裙壁部分至少在裙部的周向方向上比反推力侧上的支撑裙壁部分更大。为了将作用在支撑表面上的横向力以弹性缓冲且安全的方式转移到整个支撑结构上，连接支撑壁部分的裙部的两个壁部分分别连续地向外凸出，如沿着活塞裙至少在打开的裙部末端在销凸起下方。因此，活塞裙的横截面构造可以被描述为“蛋形”。

摘要： Piston for internal combustion engines, with an oil scraper ring disposed in an annular groove at the circumference of its head portion. The outer edge of the annular groove adjacent to the piston skirt which adjoins the head portion is bevelled to form a chamfer. In order to ensure the maintenance of an oil film sufficient to prevent dry running of the piston, on the cylinder wall, the width of the chamfer is greater on the thrust side of the piston. The width of the chamfer may decrease essentially continuously from the counter-thrust side to the pressure side.

摘要： A piston (10) comprises a piston shaft (16) and an essentially cylindrical upper region (14). The piston shaft (16) essentially comprises two opposite shaft wall portions (16) relative to the pin axis. Two pin hubs (24) are also set back relative to the piston axis in the direction of the diameter of the piston shaft (16). On the piston are formed two communicating walls (18) which connect the shaft wall portions (16), which are also set back, which extend as far as the lower edge of the essentially cylindrical region (14) and in which the pin hubs (24) are located. According to the invention, the shaft wall portions (16) are provided in a largely concurrent manner with a dimension in the circumferential direction, this dimension varying in the direction of the piston axis. The communicating walls (18) also follow the thereby determined course of the edges of the two shaft wall portions (16), with these edges extending in the direction of the piston axis.

摘要： Composite casting process for making castings, consisting in particular of light metal alloys reinforced by fiber or foamed material inserts, in particular motor parts such as pistons, cylinders, cylinder heads and motor blocks of internal combustion engines. In this process, firstly, a preform reinforced by the fiber or foamed material inserts is made by embedding and the penetration of a fiber bundle or a foamed material body in molten matrix metal or by a molten matrix metal and subsequently solidifying it. Then, the preform is immersed in a molten metal bath and subsequently inserted into a casting mould for integrally casting or casting around the final casting. In accordance with the invention, the preform is immersed into a molten metal bath which consists of the same or a similar metal or the same or similar metal alloy as the matrix metal of the preform or the metal used for integral casting or casting around the final casting and which is heated to a temperature which is higher than the melting point of the matrix material.
