Abstract

In a piston and connecting rod assembly for internal combustion engines, which assembly comprises a spherical small end portion, which is movably mounted in a recess of the piston head and in a retaining ring and which is connected to the skirt of the piston, the load-carrying capacity of the piston, which consists of a pressure-cast aluminum alloy, is increased in that the piston is reinforced by fibers, and a ring carrier which has open pores and is embedded in the ring-carrying portion and is connected thereto by a metallic bond, and a collar serving as an abutment for the retaining ring is integrally cast with the piston skirt on the inside thereof.
