Abstract

A connecting rod and crankshaft assembly comprising a crankshaft having an axis and including axially spaced end bearing surfaces in concentric relation to the axis, an arcuate throw portion extending from one of the end bearing surfaces and along a curvilinear axis and including a maximum cross section which extends perpendicularly to the curvilinear axis and which includes a maximum rectilinear distance passing through the curvilinear axis, and a crank pin extending from the throw portion in eccentric relation to the axis, a connecting rod comprising an elongated main body, and a crank pin end portion extending from the main body and including a cylindrical surface extending along an axis extending perpendicularly to the elongation of the main body and defining a crank pin aperture receiving the crank pin, and axially spaced side surfaces each including a first side surface portion located adjacent the main body and extending for an arcuate distance around the axis of less than 180 degrees, which first side surface portions are axially spaced at a first distance, and a second side surface portion located remotely from the main body and extending for an arcuate distance around the axis of more than 180 degrees, which second side surface portions are axially spaced at a second distance less than the first distance, and a bearing assembly interposed between the crank pin and the cylindrical surface of the crank pin portion of the connecting rod.
