CONNECTING ROD AND INTERNAL COMBUSTION ENGINE

摘要

A connecting rod (10) has a big end bearing eye (11) for attachment to a crankshaft, a small end bearing eye (12) for attachment to a piston, and an eccentric adjusting device (13) for adjusting an effective connecting rod length. The eccentric adjusting device (13) has eccentric rods (15, 16) that engage on an eccentric lever (14), an eccentric (36) that is guided in an aperture in the eccentric lever (14) and in the small end bearing eye (12) and an aperture for accommodating a piston pin (37). Lubricating oil bores (38, 39) are introduced into the small end bearing eye (12) via which a lubricating oil film can be built up between the small end bearing eye (12) and the eccentric (36). The small end bearing eye (12) has a larger radial wall thickness in those regions in which the lubricating oil bores (38, 39).

1. A connecting rod, having a big end bearing eye for attachment to a crankshaft, a small end bearing eye for attachment to a piston of a cylinder, and an eccentric adjusting device for adjusting an effective connecting rod length, the eccentric adjusting device having eccentric rods that engage on an eccentric lever of the eccentric adjusting device, and the eccentric adjusting device having an eccentric that is guided in an aperture in the eccentric lever and in the small end bearing eye and that has an aperture for accommodating a piston pin, lubricating oil bores being introduced into the small end bearing eye via which a lubricating oil film can be built up between the small end bearing eye and the eccentric, the small end bearing eye having a larger radial wall thickness in those regions in which the lubricating oil bores are introduced into said bearing eye than in adjoining regions of said bearing eye.
