摘要： A piston of an internal combustion engine, includes a piston upper part and a piston lower part which are supported via corresponding joining webs, in each case forming a joining zone connected in a material-to-material manner by means of a multi-orbital rotary friction weld. The joining webs and which are in each case directly connected have a wall thickness S1, S2 which is identical as far as possible. The piston encloses a combustion-chamber recess and at least one cooling duct which are made centrally or eccentrically in the piston. The combustion chamber recess and the cooling duct form a circular contour or a contour which deviates from a circular shape.

摘要： A method for producing a cooling channel system for an internal combustion engine, which has a cooling channel in the piston crown. The piston crown is adjoined by a lower piston part having a piston boss, pin bores and piston skirts. Firstly, a piston blank having a peripheral collar projecting radially in the region of the piston crown is produced, wherein the collar, forming a subsequent ring zone wall is then reshaped and, in a transition area between the piston crown and the lower piston part, a contact area for the collar is formed, and the collar is reshaped in such a way until the outer radially peripheral edge comes very close to or completely into contact with the contact area in order to form a closed cooling channel. Following the reshaping, the end region of the ring zone wall forms a defined gap (X) with respect to the upper edge of the piston skirt.

摘要： A method for producing an aluminum piston for an internal combustion engine, which piston is designed as a round skirt piston. In the region of the radially outer end faces of the piston pin bosses the piston skirt has skirt recesses extending in the direction of the piston axis. In order to be able, when using the piston, to produce skirt recesses that have any shape a piston blank is produced in a forging process using a forging die, which piston blank has inner faces that are complementary to the outer shape of the piston having skirt recesses and not-recessed regions of the piston skirt, and the piston blank can then be further machined to produce the aluminum piston.

摘要： A method for producing a piston for internal combustion engines includes the following steps: a first part is pre-fabricated by hot forging and a recess which has an undercut is formed in the first part during pre-fabrication by forming on the first part a projection, to which projection a lateral force is applied to form the undercut; a second part is pre-fabricated by hot forging and a projection is formed on this second part whose dimensions are matched to the dimensions of the recess; the two parts are joined together so that the projection on one part engages in the recess in the other part; and a compressive force is applied to the two parts which is sufficiently large and so aligned that the material of the projection on one part flows into the recess in the other part and completely fills it to connect the parts by positive fit.

摘要： A piston assembly includes a cross-head piston and a cylindrical cross pin. The cross-head piston includes a piston head having a cylindrical wall, a lateral surface and an opposite inward surface. Two spaced-apart connection ears, each having a proximal end and an opposite distal end, extend outwardly from the inward surface. Each proximal end is affixed to the inward surface and each distal end defines a pin bore passing therethrough. A piston well is defined by the inward surface and the connection ears. The cylindrical cross pin is disposed coaxially with a central axis so as to be engaged with both pin bores. The cross pin defines a central cross pin oil passage passing transversely to the central axis. The cross pin is placed in relation to the piston head so that the second end of the cross pin oil passage is directed to the piston well.

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： An engine piston (10) has a crown portion (12) generated about a longitudinal piston axis (14) and, extending axially from the crown, a pair of gudgeon pin bosses (26, 28) defining a pin axis (30) and spaced apart at opposite sides of an orthogonal thrust axis (40). A circumferentially discontinuous skirt defines lateral thrust and non-thrust bearing regions (34, 36), respectively, centered on the thrust axis, each joined by convexly bowed reinforcement ribs (62, 64, 66, 68) to the bosses. The bearing region (36) on the nun-thrust side of the piston is circumferentially shorter than thrust region (34), reducing piston mass to one side of the piston, and the reinforcement ribs are offset in pin axis direction where thy intersect the bosses. Mass reducing recesses (106, 108) are formed in the underside of the crown between the unskirted periphery (37), reinforcement ribs and bosses, the offset ribs (66, 68) permitting the recesses to extend further as at (110) and permit greater reduction in mass. The asymmetry of mass reduction permits bosses and pin axis to be offset towards the thrust region (34) whilst having the centre of mass of the piston acting through or near the pin axis.
摘要翻译：发动机活塞（10）具有围绕纵向活塞轴线（14）产生并且从冠部轴向延伸的冠部（12），一对限定销轴线（30）的舵头销凸起（26,28）在正交推力轴线（40）的相对侧分开。圆周不连续的裙部分别分别以推力轴线为中心的侧向推力轴承区域和非止推轴承区域（34,36），每个轴承区域由凸起的加强肋（62,64,66,68）连接到凸台。活塞的推力侧上的轴承区域（36）周向地比推力区域（34）短，从而将活塞质量减小到活塞的一侧，并且加强筋在销轴线方向偏移。减重凹槽（106,108）形成在未固定的周边（37），加强筋和凸台之间的冠部的下侧，允许凹部在（110）处进一步延伸并且允许更大的质量减少。质量减小的不对称允许凸台和销轴线朝向推力区域（34）偏移，同时使活塞的质心通过或靠近销轴线。
