PISTON FOR AN INTERNAL COMBUSTION ENGINE, AND PRODUCTION METHOD THEREFOR

摘要

A piston of an internal combustion engine having a piston head which has a ring zone and is adjoined by a piston skirt which encloses an inner shape, with two box walls which lie opposite one another and are set back with respect to the outer contour of the piston and with two skirt walls which are not set back with respect to the outer contour of the piston, wherein the box walls receive hubs, wherein the piston skirt has skirt supports which are connected to the hub, wherein the width of the box wall is a point of intersection between the pin axis and the constant-curvature and constant-tangent further course of the box wall, and to a method for producing a piston for internal combustion engines.

1. A piston (1) of an internal combustion engine having a piston head (11) which has a ring zone (12) and is adjoined by a piston skirt (2) which encloses an internal shape (10), with two box walls (4) which lie opposite one another and are set back with respect to the outer contour of the piston (1) and with two skirt walls (13) which are not set back with respect to the outer contour of the piston (1), the box walls (4) receiving bosses (6), the piston skirt (2) having skirt supports (3) which are connected to the boss (6), characterized in that the width (b) of the box wall (4) is a point of intersection between the pin axis (7) and the continuation with a constant curvature and tangent of the box wall (4).
