Abstract:
A device for pivotal connection of a piston having a piston head and a skirt and a connecting rod in a reciprocating-piston engine, with a connection member, which is bolted together with the piston on its side facing away from a combustion chamber and which is provided with a bearing surface for a connecting-rod eye as the pivot bearing of the connecting rod on a side of the piston, the connecting member being provided at least in the region of the bolting with planar contact faces, -which together with mating faces on the inside of the piston form a common dividing plane, and the connecting member is fixed by means of one or more connecting bolts passed through bores in the piston head whereinthe bearing surface is at least about twice greater toward a straight portion of the connecting rod than on its side facing the piston, in that the piston has one-piece construction and the connecting member is fixed in such a way inside the piston skirt that piston and connecting member is adapted to be removed through the cylinder opening on the side of the head of the cylinder once the connecting bolts have been loosened solely from a side of the combustion chamber.
