Embodiment Construction

[0028] exist Figure 1 to Figure 5 A connecting rod according to the invention is shown in , preferably with reference to the following description:

[0029] The drawing shows a connecting rod 1 with a small connecting rod hole 2 which can be rotatably connected to the piston, and in addition a large connecting rod hole 3 which has a split configuration and can Rotationally connected to the crank. The connecting rod 1 has a connecting rod body 4 located between the connecting rod head holes 2 , 3 . Due to the split configuration of the large connecting rod hole 3 , the large connecting rod hole has a connecting rod head 5 on the side of the connecting rod body and a connecting rod cap 6 which can be screwed onto said connecting rod big end 5 . Through-holes 7 are arranged in the connecting rod cover 6 on both sides of the large connecting rod hole 3 . Two through holes 7 are provided on each side of the large connecting rod hole 3 . The connecting rod big end 5 is equipped...

Abstract

The invention relates to a connecting rod having a connecting rod small end that can be connected rotatably to a piston and a connecting rod big end that is of split configuration and can be connected rotatably to a crankshaft. A connecting rod shank is between the connecting rod ends. The connecting rod big end has a big end on the connecting rod shank side and a connecting rod bearing cover that can be screwed to the big end. Through bores are arranged on both sides of the connecting rod big end in the connecting rod bearing cover. Threaded bores penetrate the big end and are flush with the through bores. Screws penetrate the through bores and are screwed into the threaded bores. The invention relates to a connecting rod where a side of the big end that faces away from the connecting rod bearing cover has a recess in the region of the respective threaded bore. The recess is directed in the direction of the connecting rod big end and is arranged eccentrically with respect to the thread axis. It is an object of the invention to develop a connecting rod of the type mentioned above where the component stresses in the region of the last thread turn of the respective threaded bore are minimized and the service life of the connecting rod can be increased in a lasting manner.

Description

technical field [0001] The present invention relates to a connecting rod having a small connecting rod hole rotatably connected to a piston and a large connecting rod hole of a split configuration rotatably connected to a crank and having A connecting rod body between the connecting rod head holes, the large connecting rod hole has a connecting rod big end on the side of the connecting rod body and a connecting rod cover that can be screwed onto the connecting rod big end, where the connecting rod Through-holes are arranged in the cover on both sides of the big connecting rod hole, and in the big end of the connecting rod are arranged threaded holes flush with said through-holes and penetrating the big end of the connecting rod, through which screws penetrate and are screwed into these threaded holes. Background technique [0002] During operation, the connecting rod is subjected to high alternating tension / compression loads resulting from the superposition of flexural stre...
