Piston pin for use with mechanical contact with piston of machine, particularly internal combustion engine, has double-T-support profile in cross section, where central cross-sectional area contains variable contour thickening

摘要

The piston pin (1) has a double-T-support profile (2) in a cross section, where a central cross-sectional area contains a variable contour thickening. The crescent-shaped formations (4b) are provided in the peripheral area (4a) of the cross-sectional area. The relief recesses are shown in a longitudinal girder area (5), where the recesses are made as two holes (7a,7b). A conformal contour is provided at the ends with piston adapted structures. The pin is provided with the screws and is locked with an integrated groove.
