ABSTRACT:
The invention relates to a piston, particularly of light metal, for internal combustion engines, comprising a piston skirt substantially closed in the peripheral direction, pin bosses set back with respect to the piston skirt diameter in the direction of the piston axis, and two supporting skirt wall sections which thus remain on the piston skirt on the thrust and the counter-thrust side. The supporting skirt wall section on the thrust side is larger at least in the peripheral direction of the skirt than the supporting skirt wall section on the counter-thrust side.
In order to divert the lateral forces acting on the supporting surfaces to the entire supporting structure in an elastically cushioned but safe manner, the two wall sections of the skirt connecting the supporting wall sections are respectively continuously curved convexly outwards as seen along the periphery of the piston skirt at least at the open skirt end beneath the pin bosses. The cross-sectional configuration of the piston skirt can therefore be described as being "egg-shaped".
