摘要： A monobloc piston (10) has a piston head (12) with a combustion bowl (28) formed in its upper surface (16) and a plurality of ring grooves (20, 22, 24) formed in an outer surface (26) of a ring belt (14). An oil cooling gallery (32) is formed in the piston head (12) which is defined in part by a wall of the combustion bowl (28) and ring belt (14). The piston (10) has a unitized, immovable piston skirt (46) which is formed as one piece with the pin bosses (38) and fixed at its upper end to the ring belt (14). Piston rings (58, 60, 62) are disposed in each of the ring grooves (20, 22, 24), and the piston head (12) is further formed with an oil drainage groove (52) which is located below the lowest of the ring grooves (62).

摘要： A monobloc piston has at least two steel parts (13, 15) welded together to define an inner cooling gallery (32). An outer ring belt (14) is spaced from an inner annular support wall (34) and is joined by a combustion bowl (28) and a lower wall. A pair of pin bosses (38) have axially aligned pin bores (44). A skirt (46) is formed as one immovable piece with the pin bores. The piston has the following dimensional relationships: ISMD = 42-55% of BD, where ISMD is a mean diameter on the inner support wall and BD is an outer diameter of the ring belt wall, ISW = 3-8% of BD, where ISW is a sectional width of inner wall; CH > 53% of BD where CH is a compression height measured between the pin bore axis and the upper surface, TLH > 4% of BD, where TLH is a top land height measured between the top of the upper ring groove and the upper surface, SL = 30-80% of BD, where SL is a length of the skirt measured between the upper and lower ends of the skirt, SW = 2.5 - 6.5% of BD, where SW is a thickness of the skirt, and GV = 150-250% of BD2 and 5-20% of BD2 x CH, where GV is a volume of the oil gallery.

摘要： A steel monobloc piston for diesel engines is formed with a relatively short piston skirt whose lower edge resides below the axis of the pin bores of the piston, but located at or above a lowest tangent point of the pin bores. The piston body preferably has a closed oil coiling gallery and the skirt is preferably joined at its upper end to an outer wall of the piston in which a plurality of ring grooves are formed.

摘要： The present invention relates to a connecting-rod and piston assembly that comprises a cylinder and a piston, said piston comprising a head, a skirt and a support element. The piston is attached to the connecting rod by a pin, said connecting rod being mounted on the central cylindrical part of the pin. The ends of pin are made in the shape of cylindrical segments which are coaxial to the cylindrical part of said pin and have smooth surfaces parallel to the pin longitudinal axis. Fixing plates lie against the smooth surfaces of the pin ends. Said plates comprise openings in which threaded members pull the pin ends toward cylindrical recesses in the support element, the ends and the support element being simultaneously pulled towards the cylinder head.
