Title:
CONNECTING-ROD BUSHING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/068054
Kind Code:
A1
Abstract:
A connecting-rod bushing structure, which relates to an engine and is mainly solves the technical problem of the poor lubrication of an existing connecting-rod bushing. The connecting-rod bushing structure comprises a piston (1), a connecting rod (2) and a bushing (3), wherein a connecting-rod small end (4) of the connecting rod (2) is rotationally connected to the piston (1) via the bushing (3) and a piston pin (5); two sides of the top of the bushing (3) are respectively provided with a bushing oil intake hole (6); the connecting-rod small end (4) is internally provided with connecting-rod oil intake holes (7) corresponding to the bushing oil intake holes (6); the piston (1) is internally provided with oil output holes (8) corresponding to the connecting-rod oil intake holes (7); and the oil output holes (8) are in communication with an oil channel (9) in the piston (1). By means of providing the bushing oil intake holes (6), the connecting-rod oil intake holes (7) and the oil output holes (8), lubricating oil in the oil channel (9) in the piston (1) sequentially passes through the oil output holes (8), the connecting-rod oil intake holes (7) and the bushing oil intake holes (6) and then enters the inside of the bushing (3), such that the lubricating effect of the bushing (3) can be effectively improved.
