Claims
- 1. A connecting rod for an internal combustion engine having a crankshaft axis and a piston axis said connecting rod comprising:
- a pair of flanges disposed in parallel relation with a plane including the crankshaft axis and the piston pin axis, each flange having a body and edges, each said edge having a lateral rounded projection thereon, such that said edges are thicker than said body; and
- a web connecting said pair of flanges together, said web and flanges thereby forming a rod portion having a generally I-shaped section.
- 2. A connecting rod according to claim 1, wherein said side edges have inner facing surfaces provided with projections.
- 3. The connecting rod of claim 2 wherein said projections are curved.
- 4. A connecting rod according to claim 1, wherein said web is formed with grooves extending in the elongate direction each at outer surfaces of said two flanges in such a manner as to be in alignment with a portion where said web is connected with said two flanges.
- 5. The connecting rod of claim 1 wherein said web includes a bore.
- 6. A connecting rod for an internal combustion engine, said connecting rod having a large end half portion engageable to a crankshaft having an axis and a small end portion engageable to a piston pin having an axis comprising:
- a pair of flanges disposed in parallel relation to a crankshaft plane, said crankshaft plane including the crankshaft and piston pin axes,
- each flange having a body and side edges, and each side edge having a lateral rounded projection thereon such that said edges are thicker than said body,
- said pair of flanges connected to each other by a web to form a rod portion having an I-shaped cross-section; and
- a pair of planar gussets disposed on said large end half portion, said gussets oriented in a plane perpendicular to the crankshaft plane.
- 7. The connecting rod according to claim 6 wherein each lateral projection on said flanges are oriented such that said projections face each other.
