Embodiment Construction

[0043] The drawing shows a combination according to the invention of a piston 10 and a connecting rod 12 for a crank drive of an internal combustion engine, for example in a motor vehicle.

[0044] The piston 10 comprises a one-piece upper piston part 14 and a likewise one-piece lower piston part 16 , which are connected to one another in a non-positive manner when the combination is assembled.

[0045] The upper piston part 14 forms a piston head 18 and a piston body 20 . The piston head 18 has an approximately cylindrical outer contour, wherein the side surfaces of the cylindrical outer contour form sections of the piston skirt 22 of the piston 10 . An annular groove provided for receiving the piston ring is brought into this side surface. The (closed) end face of the piston upper part 14 distal to the piston lower part 16 (and also the connecting rod 12 ) is the piston crown 24 of the piston 10 . On the side facing away from the piston crown 24 , the piston head 18 merges...

Abstract

The invention relates to a combination of a piston (10) and a rod (12) pivotably mounted in a bearing receptacle (44) of the piston (10), wherein the piston (10) comprises a piston upper part (14) forming the piston crown (24) and a piston lower part (16) forming at least one section of the piston skirt (22), which are connectable in the context of an assembly of the combination, and wherein a rod head (34) of the rod (12) can be inserted in a first rotational direction into the bearing receptacle (44), and is secured against a loosening out of the bearing receptacle (44) in a second rotational direction rotated by an angular distance about the longitudinal axis (52) of the rod (12), characterized in that, after the assembly of the combination, the rod (12) is secured against a rotation out of the second rotational direction into the first rotational direction by means of the piston lower part (16) connected to the piston upper part (14). In this way, in particular, a simple assembly can be carried out for the combination of piston and rod.

Description

technical field [0001] The invention relates to a combination of a piston and a connecting rod mounted pivotably in a bearing receptacle of the piston, wherein the piston comprises a piston upper part forming a piston crown and a piston skirt forming a piston skirt The piston lower part of at least one section of which can be connected in the case of an assembly transmission (or linkage, ie Triebwerk), and wherein the connecting rod head of the connecting rod can be inserted into the first rotational orientation Secured against release from the bearing receptacle in the bearing receptacle and in a second rotational orientation twisted by an angular distance about the longitudinal axis. Background technique [0002] The combination of a piston and a connecting rod mounted pivotably in a bearing receptacle of the piston is used, for example, in a crankshaft drive of an internal combustion engine. The combination is used here to convert the cyclic reciprocating motion of the p...
