    • A piston for an internal combustion engine may include a piston head and a piston shaft. The piston shaft may have two shaft walls, one arranged on a pressure side and the other arranged on a counter-pressure side. Two box walls may have pin bosses and connect the shaft walls. Each of the box walls may have a first partial wall section and a second partial wall section. The first partial wall section may extend between the pin boss and the shaft wall arranged on the pressure side. The second partial wall section may extend between the pin boss and the shaft wall arranged on the counter-pressure side. A first longitudinal centre line of the first partial wall section is may be convergent to a second longitudinal centre line of the second partial wall section, wherein the first and second longitudinal centre lines—intersect each other outside the piston.
    • 用于内燃机的活塞可以包括活塞头和活塞轴。 活塞轴可以具有两个轴壁,一个布置在压力侧,另一个布置在反压侧。 两个箱壁可以具有销凸起并连接轴壁。 每个箱壁可以具有第一部分壁部分和第二部分壁部分。 第一部分壁部分可以在销凸台和布置在压力侧的轴壁之间延伸。 第二部分壁部分可以在销凸台和布置在反压侧的轴壁之间延伸。 第一部分壁部分的第一纵向中心线可以会聚到第二部分壁部分的第二纵向中心线,其中第一和第二纵向中心线在活塞外部彼此相交。

    • The invention proposes a piston (10) for an internal combustion engine, having a piston crown (11), having a fire land (12), having an encircling ring section (13) which has annular grooves (14), and having a piston shank (15) which has two shank walls (16, 17) arranged on the pressure side (DS) and on the counterpressure side (GDS) and two box walls (18, 19) which connect the shank walls (16, 17) to one another, wherein the box walls (18, 19) are provided with pin hubs (21) which have hub bores (22), and wherein the shank wall (16) arranged on the pressure side (DS) is shorter, as viewed in the circumferential direction of the piston (10), than the shank wall (17) arranged on the counterpressure side (GDS). To reduce the loading of the piston, the pressure-side box walls (18) run rectilinearly and obliquely, wherein the spacing of the box walls (18) is greater in the region of the pin hubs (21) than in the region of the pressure-side shank wall (16).
    • 本发明提出了一种内燃机的活塞(10),其具有具有火land(12)的活塞冠(11),所述活塞穹顶(12)具有环形环部分(13),所述环形部分具有环形槽(14) 具有设置在压力侧(DS)和反压侧(GDS)上的两个柄壁(16,17)的柄(15)和将柄壁(16,17)连接到 另一方面,其中箱壁(18,19)设置有具有轮毂孔(22)的销毂(21),并且其中布置在压力侧(DS)上的柄壁(16)较短,如 活塞(10)的周向方向比设置在反压侧(GDS)上的柄壁(17)更大。 为了减小活塞的负载,压力侧盒壁18直线地和倾斜地运行,其中盒壁(18)的间隔在销毂(21)的区域中比在区域 压力侧柄壁(16)。
