Abstract
A multi-piece connecting rod has the large eye end formed with a yoke receiving a bearing bracket supported on an angled wedge surface by an angled counter surface of a wedge. The wedge is carried by a pin-like bolt between legs of the yoke and includes a threaded portion engaged by the bolt for tightening the angled wedge surfaces to clamp the bearing bracket in position.
Claims4
A connecting rod having a split lower eye including a crankpin opening, wherein said eye comprises a bearing yoke including first and second spaced legs, a bearing bracket received in the yoke between said legs and forming with the yoke said crankpin opening, said bearing bracket having an angled wedge surface on a side opposite the crankpin opening and inclined away from said opening in a direction toward said first leg, a wedge member disposed between the legs on said opposite side of the bearing bracket and having an angled counter surface engaging said angled wedge surface of the bearing bracket, said wedge member being the sole means for urging said bearing bracket against the yoke in a direction toward said crankpin opening, the wedge member being substantially shorter than the distance between said legs to permit lateral adjusting movement of the wedge member between the legs and being initially installed in a position spaced from said first leg to permit subsequent lateral adjustment of the wedge member toward said first leg to urge said bearing bracket member toward said crankpin opening, and a bolt extending laterally through coaxial bores in said wedge member and said legs to retain said wedge member between said legs and having means for restraining lateral motion of the bolt in a direction from said first leg toward said second leg, said bolt and said bore of the wedge member having coacting threaded portions with interengaging threads to laterally adjust the wedge member toward said first leg upon prescribed rotation of said bolt in said bores.
