  • Multi-axially forged piston
    Patent number: 7870669
    Abstract: A multi-axially forged mono-bloc piston includes a lower crown part forged of steel and including a pair of pin bosses and an integral skirt formed as one piece with the pin bosses 20. The lower crown part is friction welded to an upper crown part to form at least one closed oil gallery within the piston head. The lower crown part is forged in the longitudinal direction of the piston as well as laterally to impart longitudinal and laterally forged features of the piston. The laterally forged features may comprise undercut recesses formed in the piston skirt to reduce material in the overall piston structure. The lateral forging may also result in the piston skirt portion being discoupled from the piston head by laterally forged slots formed in the lower crown part 14 between the skirt and head.

  • One-piece integral skirt piston and method of making the same
    Patent number: 6260472
    Abstract: A one-piece piston (20) formed by an upper crown (28) and a lower crown (30) having an integral skirt (24, 26). The upper crown (28) includes an upper surface (32) and a lower surface (34, 42). The lower crown (30) includes an upper surface (50) and two pin bosses (52, 54). The upper crown (28) has a first collar (44) and the lower crown (30) has a second collar (64). In addition, skirt ribs (24, 26) connect the two pin bosses (52, 54). The first and second collars (44, 64) are secured together to form the one-piece piston (20).
