CONNECTING ROD

摘要

A connecting rod for a device includes a rod having a large end, and a cap attached to the large end. The large end of the rod and the cap cooperate to define a first side surface and a second side surface disposed opposite to each other. The large end of the rod and the cap further define a crankshaft bore that extends along a crank axis between the first side surface and the second side surface. A thrust surface is defined by at least one of the first side surface or the second side surface, and is disposed on a thrust plane. The thrust surface includes at least one recessed region that extends inward away from the thrust plane of the thrust surface. Each of the thrust surfaces include ramps that extend between the recessed regions and the flat regions at the thrust plane of the thrust surface.

1. A connecting rod comprising:
a rod having a large end; a cap attached to the large end of the rod; wherein the large end of the rod and the cap cooperate to define a first side surface and a second side surface disposed opposite to each other, and a crankshaft bore extending along and concentric with a crank axis between the first side surface and the second side surface; and a thrust surface defined by at least one of the first side surface or the second side surface, and including a plurality of recessed regions and a plurality of flat regions aligned along a thrust plane of the thrust surface, with each recessed region including a central portion extending inward away from the thrust plane of the thrust surface, and with each adjacent pair of the recessed regions separated by one of the plurality of flat regions; wherein each of the recessed regions includes a first ramp extending between an adjacent flat region and its respective central portion.
