Abstract
A device for pivotal connection of piston (1) and connecting rod (10) in a reciprocating-piston engine comprises a connecting member (6) integral with the piston, with a bearing surface (9) for a connecting-rod eye (11), which together with the bearing surface (9) forms the pivot bearing of the connecting rod (10) on the piston side; the connecting member (6) is provided at least in the region of the bolting with planar contact faces (7), which together with mating faces (8) on the inside of the piston form a common dividing plane (13); the connecting member (6) is fixed on the side of the piston (1) facing away from the combustion chamber by means of one or more connecting bolts (4) passed through bores in the piston head (2); the bearing surface (9) is much broader toward the straight portion (10) of the connecting rod than on its side facing the piston (10).
