  • Connecting rod
    Patent number: 4836045
    Abstract: A multi-piece connecting rod is provided in which the piston pin bearing boss is divided along a transverse plane perpendicular to its bearing axis and is formed by extensions of two rod components provided with bearing holes while the crankpin bearing boss is divided along an axial plane through its bearing axis. For installation, the rod components are pivotable about the piston pin axis to open or unfold the crankpin end to receive the crankpin prior to closing and securing the rod components in their closed positions.

  • Engine crankshaft supports
    Patent number: 4836159
    Abstract: In an internal combustion engine, in the crankcase (2), as shown in FIG. 1, each bearing cap (7) supporting a crankshaft bearing is, in each instance, bolted to its bearing web (4) with only a single screw (8). On the side of the bearing cap (7) opposite the screw (8), there is provided on the bearing web (4) a supporting surface (11), against which the bearing cap (7) abuts, so that some of the forces parallel to the cylinder axis can be conveyed directly into the crankcase (2).
