Abstract
Official abstract text for this publication.
A bushing may include a support surface and a sliding surface having a perimeter midpoint. The sliding surface of the bushing may have a convex profile in relation to a cross section of the bushing. The convex profile may be offset from the perimeter midpoint of the sliding surface of the bushing.
First claim
Opening claim text (preview).
The invention claimed is: 1. A bushing comprising: a support surface; and a sliding surface having a perimeter midpoint; wherein said sliding surface has a convex profile in relation to a cross section of said bushing; and said convex profile is offset from said perimeter midpoint of the sliding surface. 2. The bushing as claimed in claim 1 , wherein said bushing is a bi-metal bushing. 3. The bushing as claimed in claim 1 , wherein said bushing is a tri-metal bushing. 4. The bushing as claimed in claim 1 , wherein said convex profile is arc-shaped in relation to the cross section of the bushing. 5. The bushing as claimed in claim 1 , wherein said convex profile is trapezoid-shaped in relation to the cross section of the bushing. 6. The bushing as claimed in claim 1 , wherein said offset from the perimeter midpoint of the sliding surface is at an angle of between 10° and 25°. 7. The bushing as claimed in claim 1 , wherein said offset from the perimeter midpoint of the sliding surface is at an angle of between 25° and 55°. 8. The bushing as claimed in claim 1 , wherein the height of said convex profile is between 2 and 20 μm. 9. The bushing as claimed in claim 1 , wherein said convex profile has an angular length of 0 to 90°. 10. The bushing as claimed in claim 1 , wherein said offset from the perimeter midpoint of the sliding surface is at an angle of between 14° and 18°. 11. The bushing as claimed in claim 1 , wherein said offset from the perimeter midpoint of the sliding surface is at an angle of approximately 16°. 12. The bushing as claimed in claim 1 , wherein said offset from the perimeter midpoint of the sliding surface is at an angle of between 30° and 50°. 13. The bushing as claimed in claim 1 , wherein said offset from the perimeter midpoint of the sliding surface is at an angle of between 35° and 45°. 14. The bushing as claimed in claim 1 , wherein the height of said convex profile is between 3 and 15 μm. 15. The bushing as claimed in claim 1 , wherein the height of said convex profile is approximately 10 μm. 16. The bushing as claimed in claim 1 , wherein said convex profile has an angular length between 20° and 70°. 17. The bushing as claimed in claim 1 , wherein said convex profile has an angular length of approximately 60°. 18. An internal combustion engine comprising: at least one bearing; a connecting rod; and at least one bushing having: a support surface; and a sliding surface having a perimeter midpoint; wherein said sliding surface has a convex profile in relation to a cross section of said bushing; and said convex profile is offset from said perimeter midpoint of the sliding surface. 19. The internal combustion engine as claimed in claim 18 , wherein said bushing is a bi-metal bushing. 20. A bushing comprising: a support surface; and a sliding surface having a perimeter midpoint; wherein said sliding surface has an arc-shaped convex profile in relation to a cross section of said bushing; wherein said bushing is one of a bi-metal bushing and a tri-metal bushing; and wherein the convex profile has a radius of curvature such that a highest point of the convex profile occurs at a midpoint of the convex profile in an axial direction.
