Abstract

In a piston head of a multiple component piston for internal combustion engines, the piston floor continues radially outwards into the ring section which is provided with the piston ring grooves, the supports which carry the hubs are arranged at a distance from the inner face of the ring section and the piston pin which bears the piston shaft can be mounted in the bores of the piston pin boss. An improved manufacture of the piston head is ensured by connecting the ring section with the piston floor via a weld, solder, friction or positive locking joint.
