CONNECTING ROD AND INTERNAL COMBUSTION ENGINE

摘要

A connecting rod (10) has a pin bearing eye connected to a crankshaft and a connecting rod bearing eye (12) connected to a piston. An eccentric adjusting device (13) adjusts an effective connecting rod length and has eccentric rods (15, 16) that act on an eccentric lever (14) of the adjusting device (13). The eccentric adjusting device (13) has an eccentric (36) guided in a recess of the lever (14) and a recess for receiving a gudgeon pin (37). Lubricating oil bores extend radially of the eccentric in the connecting rod bearing eye (12) and in the eccentric (36). Lubricating oil builds up via the lubricating oil bores between the connecting rod bearing eye (12) and the eccentric (36) and between the eccentric (36) and the gudgeon pin (37). Lubricating oil bores of the eccentric (36) are diametrically larger than lubricating oil bores of the connecting rod bearing eye (12).

主权项

1. A connecting rod, comprising: a pin bearing eye for connecting to a crankshaft and a connecting rod bearing eye for connecting 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 act on an eccentric lever of the eccentric adjusting device, the eccentric adjusting device having an eccentric that is guided in a bore or recess of the eccentric lever and that has a bore or recess for receiving a gudgeon pin, lubricating oil bores made in the connecting rod bearing eye and in the eccentric and extending in a radial direction of the eccentric and the connecting rod bearing eye, the lubricating oil bores enabling a lubricating oil film to be built up between the connecting rod bearing eye and the eccentric and between the eccentric and the gudgeon pin, each lubricating oil bore of the eccentric having a greater diameter than each lubricating oil bore of the connecting rod bearing eye.
