摘要： The invention relates to gudgeon pin bushes which find application in highly-stressed engines, with the problem of a tendency to pit, in particular in the middle regions (with relation to the radial axis of the bush), on starting the motor. According to the invention, the problem can be avoided whereby the friction surfaces of a gudgeon pin bush, at least in the high loading region, have the following parameters measured over the bush cross-section in the axial direction: the support percentage is a minimum of 99.0% to a depth of at most 1.800 m, the depth of the roughness core profile is at most 0.30 m, the proportion of the material Mr1 of the roughness core profile is at most 8%. The gudgeon pin bush can be obtained by finishing the bearing surface of the gudgeon pin bush using a surface machining method.

摘要： A multi-axially forged mono-bloc piston includes a lower crown part forged of steel and including a pair of pin bosses and an integral skirt formed as one piece with the pin bosses 20. The lower crown part is friction welded to an upper crown part to form at least one closed oil gallery within the piston head. The lower crown part is forged in the longitudinal direction of the piston as well as laterally to impart longitudinal and laterally forged features of the piston. The laterally forged features may comprise undercut recesses formed in the piston skirt to reduce material in the overall piston structure. The lateral forging may also result in the piston skirt portion being discoupled from the piston head by laterally forged slots formed in the lower crown part 14 between the skirt and head.

摘要： A method for the production of a one piece piston for an internal combustion engine. The piston has a ring shaped cooling channel arranged in an outer region of a piston head. The channel is partially closed off by a circumferential projection structured as an oil groove. The piston is produced in a simple and inexpensive manner using a piston blank using cutting work such as lathing.

摘要： A porous body is formed and joined to the component by sintering a metal powder to the component. The porous body and component are placed into a piston casting die. Molten metal is poured into the die such that the porous body becomes infiltrated with the molten metal and the molten metal is allowed to solidify. The porous body may be formed by sintering loose metal powder to the component, or by forming a separate body by die pressing of metal powder and which body may be subsequently sintered and joined to the component.

摘要： A device, such as a gudgeon pin, for connecting a piston of a reciprocating internal combustion agent to a connecting-rod comprises at least in part a fibre-reinforced composite material. The device further comprises a metallic sliding bearing having a circular cylindrical external surface. The sliding bearing layer is arranged on the external surface of the fibre-reinforced composite material. A plurality of fibre layers, which run in differing directions, are arranged in the composite material, and the sliding bearing layer is divided in the transition region from a piston to a connecting-rod. The gudgeon pin has alternate layers, in which fibres are arranged orthogonally to fibres in an adjacent fibre layer. The fibres run parallel to the gudgeon pin axis in one layer and orthogonally thereto in the two adjacent layers. The composite material layer has on its exterior a metallic sliding bearing layer which is applied either by electro-plating or by vapour deposition, or a sliding bearing bush is slipped over the composite material layer.

摘要： A method of manufacturing a connecting rod for reciprocating piston engines, especially axial cylinder-type reciprocating piston engines, with the connecting rod including a tubular shaft having hollow spherical shells mounted at the ends thereof. The tubular shaft and the hollow spherical shells are constructed from a sheet metal-like material and are joined to form a one-piece connecting rod body by way of welding joints. A lubricating tube is arranged within the tubular shaft and extends between the spherical shells so as to equalize the lubricant between surfaces of the hollow spherical shells.
