Abstract
Official abstract text for this publication.
A connecting rod ( 10 ) has a big end bearing eye ( 11 ) for attachment to a crankshaft and a small end bearing eye ( 12 ) for attachment to a piston of a cylinder. An eccentric adjusting device ( 13 ) adjusts an effective connecting rod length. The eccentric adjusting device ( 13 ) has eccentric rods ( 15, 16 ) that engage on an eccentric lever ( 14 ) of the eccentric adjusting device ( 13 ) so that, in the region of each eccentric rod ( 15, 16 ), a connecting pin ( 36 ) extends through apertures in the eccentric lever ( 14 ) and in the respective eccentric rod ( 15, 16 ). The aperture ( 37 ) in the respective eccentric rod ( 15, 16 ), through which the respective connecting pin ( 36 ) extends, and/or a section of the respective connecting pin ( 36 ) that extends through the aperture ( 37 ) in the respective eccentric rod ( 15, 16 ), has/have arched contours, at least in some section or sections.
First claim
Opening claim text (preview).
What is claimed is: 1 . A connecting rod, comprising a big end bearing eye for attachment to a crankshaft, a small end bearing eye for attachment to a piston of a cylinder, and an eccentric adjusting device for adjusting an effective connecting rod length, the eccentric adjusting device having eccentric rods that engage on an eccentric lever of the eccentric adjusting device so that, in a region of each eccentric rod, a connecting pin extends through apertures in the eccentric lever and in the respective eccentric rod, the aperture in the respective eccentric rod, through which the respective connecting pin extends, and/or a section of the respective connecting pin that extends through the aperture in the respective eccentric rod, has arched contours, at least in some section or sections. 2 . The connecting rod of claim 1 , wherein the aperture in the respective eccentric rod, through which the respective connecting pin extends, and/or that section of the respective connecting pin that extends through the aperture in the respective eccentric rod are contoured so as to be arched spherically or in a barrel shape or convexly, at least in some section or sections. 3 . The connecting rod of claim 1 , wherein the aperture in the respective eccentric rod has cylindrical contours, and sections of the respective connecting pin that extend through the aperture in the respective eccentric rod has arched contours, at least in some section or sections. 4 . The connecting rod of claim 1 , wherein the aperture in the respective eccentric rod has arched contours, at least in some section or sections, and that section of the respective connecting pin that extends through the aperture in the respective eccentric rod has cylindrical contours. 5 . The connecting rod of claim 1 , wherein the aperture in the respective eccentric rod and that section of the respective connecting pin that extends through the aperture in the respective eccentric rod both have arched contours, at least in some section or sections. 6 . An internal combustion engine that has an adjustable compression ratio, comprising at least one cylinder and a crankshaft on which the connecting rod of claim 1 engages.
