Abstract (en)

[origin: WO2015055578A1] The invention relates to 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 inner 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), wherein the box walls (4) receive hubs (6), wherein the piston skirt (2) has skirt supports (3) which are connected to the hub (6), wherein the width (b) of the box wall (4) is a point of intersection between the pin axis (7) and the constant-curvature and constant-tangent further course of the box wall (4), and to a method for producing a piston (1) for internal combustion engines.
