Title:
BUSH OF CONNECTING ROD
Document Type and Number:
Japanese Patent JP2018096522
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a bush which can suppress the generation of the seizure of the bush of a connecting rod and a piston pin even if an engine is boosted in in-cylinder pressure.SOLUTION: A bush 40 of a connecting rod comprises first and second introduction parts 47a, 47b which are arranged in first and second positions 45a, 45b, respectively, in order to guide a lubricant to an internal peripheral part 41, a cross section of an inside face 43 orthogonal to an axial direction of a piston pin 30 in an axial direction has a substantially-long circular shape, and a second inside diameter along a direction substantially orthogonal to a first inside diameter is larger than the first inside diameter of the internal peripheral part. When a position of the piston pin 30 is deviated to first and second directions d1, d2, a clearance between the inside face 43 and the piston pin 30 which is formed between the first and second positions 45a, 45b is larger than a clearance between the inside face 43 of a main load part L and the piston pin 30.SELECTED DRAWING: Figure 3
