CRANK DEVICE FOR V TYPE INTERNAL COMBUSTION ENGINE

摘要

PURPOSE: To decrease a friction loss generated from an axial stop by guiding each connecting rod by an axial stop surface and enlarging a height of the axial stop face so as to make an overlapping sectional area. CONSTITUTION: A connecting rod 11 or 12 which is provided at a connecting rod large edge 13 or 12 is guided by axial die faces 17 or 16 which is provided the large edge 13 or 12 for connecting rods for an adjusting connecting rod 11 or 10. A height of the axial die faces 16 or 17 is enlarged so as to make and a linked overlapping sectional area for both of the axial stop surface 17 or 16 of the connecting rods 11 or 10. Therefore, the friction loss generated from an axial stop of the connecting rod can be decreased sharply.
