Connecting rod
First Claim
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;
wherein the first side surface and the second side surface are disposed parallel to each other and perpendicular to the crank axis;
a thrust surface defined by at least one of the first side surface or the second side surface, wherein the thrust surface defines a thrust plane, and includes a plurality of recessed regions and a plurality of flat regions aligned relative to the thrust plane of the thrust surface, with each recessed region including a central portion spaced inward away from the thrust plane of the thrust surface along the crank axis, and with each adjacent pair of the recessed regions separated by one of the plurality of flat regions; and
wherein each of the recessed regions includes a first ramp extending between an adjacent flat region and its respective central portion.

Abstract
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.

14. A device comprising:
-
a crankshaft including a rod journal extending along and concentric about a crank axis, and a shoulder disposed at an axial end of the rod journal and extending radially outward and away from the rod journal relative to the crank axis; a connecting rod coupled to the crankshaft, the connecting rod including; 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 the crank axis between the first side surface and the second side surface, wherein the crankshaft passes through the crankshaft bore; wherein the first side surface and the second side surface are disposed parallel to each other and perpendicular to the crank axis; a thrust surface defined by at least one of the first side surface or the second side surface, and disposed against the shoulder of the crankshaft; wherein the thrust surface defines a thrust plane disposed perpendicular to the crank axis, and includes a plurality of recessed regions and a plurality of flat regions aligned relative to the 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 along the crank axis, and with each adjacent pair of the recessed regions separated by one of the plurality of flat regions; and wherein each of the recessed regions includes a first ramp extending between an adjacent flat region and its respective central portion. - View Dependent Claims (15, 16, 17, 18, 20)
