Definitions

  • the invention relates to a cast piston with support ribs for an internal combustion engine and to a method for producing such a piston.
  • Pistons for internal combustion engines are exposed to high mechanical and thermal stresses during operation.
  • the piston structure, the materials used and other design features depending on its intended use, for example, in terms of structural rigidity or its weight can be optimized. Other constraints to consider include cost and longevity.
  • a conflict of objectives lies in maximizing the structural rigidity and minimizing the weight of the piston at the same time.
  • An increase in the structural rigidity can be achieved by reinforcing parts and / or regions of the piston which are subjected to particularly high loads. Such a reinforcement increases the weight of the piston. This in turn entails an increase in consumption and an increase in manufacturing and operating costs.
  • the EP 1 561 938 A1 shows a piston in which ribs are attached to the pin bores, which are completely connected to the piston head along a lower side and are located substantially below the pin bore.
  • the DE 10 2005 043 747 A1 shows a piston for an internal combustion engine, wherein the support ribs are part of the Form the circumference of the piston skirt and are completely connected to the piston crown along the edge facing the piston crown.
  • the ribs known in the art are directed to the field of application, needs and manufacturing limitations of forged pistons.
  • the DE 699 01 902 T2 describes a piston for use in a motor.
  • the piston has a plurality of struts which are provided in the piston skirt.
  • the DE 1 805 533 A refers to a piston for internal combustion engines, wherein the piston has flat inserts which are perpendicular to the pin axis.
  • the GB 431 743 A discloses a piston with struts provided on the piston skirt.
  • the invention is therefore based on the object to provide a cast piston with improved structural rigidity with simultaneous weight optimization and a suitable manufacturing process.
  • a cast piston for an internal combustion engine has a piston head, a cylindrical piston head, which adjoins the piston crown, and an at least partially hollow piston shaft, which is located on the side facing away from the piston crown of the piston head.
  • the cast piston is characterized in that it comprises one or more support ribs which are located at least partially in the piston skirt, and at least one support rib has a recess on the side facing the piston crown.
  • the in the Piston shaft provided support ribs stiffen the piston skirt. Furthermore, by appropriate arrangement of the support ribs targeted areas in which high loads occur and require a stiffening, can be strengthened. Due to a targeted reinforcement can, depending on the scope of the piston, material elsewhere, for example, be reduced to the wall thickness of the piston skirt in favor of its weight optimization.
  • the support ribs are located inside the piston skirt to stiffen areas in the vicinity of bolt holes provided in the peripheral wall of the piston skirt. Recesses of the support ribs on the side facing the piston crown serve to reduce weight in areas that do not require additional stiffening. Furthermore, spray oil and / or guided oil can reach the bolt through these recesses. This allows the piston in the area of the bolt holes and the connecting rod sufficiently cooled and can be better lubricated.
  • the support ribs may be formed integrally with the piston skirt or cast in order to obtain the greatest possible material homogeneity, in particular in those areas which are exposed to great loads. Further, the piston can be manufactured by the one-piece casting without further additional processing of the ribs. The formation of the ribs is thus integrated into the casting process. Such a method is therefore particularly productive and therefore also suitable for the production of large quantities.
  • the support ribs connect to walls of the piston body in the vicinity of the piston bore in order to combine a reinforcement by flanges and support ribs.
  • the cast piston is made of aluminum to reduce the weight of the piston.
  • Aluminum has the necessary heat resistance, lightness and structural rigidity.
  • the support ribs are arranged substantially parallel to the pin axis.
  • the bolt axis is defined by two bolt holes. Such an arrangement effectively enhances the high stress areas around the pin holes.
  • the parallel arrangement of the support ribs to the bolt axis represents the shortest connection of the two opposite bolt body sides, whereby material can be saved and therefore the weight of the piston can be optimized.
  • the support ribs are substantially perpendicular to walls of the piston skirt to optimize the structural rigidity of the piston.
  • the support ribs are formed flat, wherein an edge of such a rib extends substantially parallel to the piston crown and at least one adjoining this edge surface is arranged substantially perpendicular to the piston crown to improve the structural rigidity of the piston.
  • a reinforcement on which there is preferably a mirror-symmetrical support rib on both sides of the bolt holes, promises an effective improvement of the structural rigidity around the heavily stressed areas of the bolt holes.
  • the support ribs are not formed on the piston head. Connecting the support ribs with the piston crown is not necessary, which can be exploited in favor of a lower material consumption.
  • each support rib connects two sides of the piston skirt.
  • the edge of the support ribs facing away from the piston crown is farther from the piston crown than the central axis of the bolt bores, in particular to stiffen the piston skirt.
  • this edge can also be further away from the piston crown than the bolt holes in total, and the recess can extend from the piston crown beyond the central axis and into the region of the end of the bolt bore facing away from the piston crown.
  • the object is further achieved by a method for producing the above cast piston in which the recess is formed, for example by a suitable core, during the casting of the support ribs.
  • Fig. 1 is a perspective view of a cast piston according to the invention.
  • the inventive cast piston 1 in Fig. 1 has a piston head 10 with a piston head 12 and a piston stem 20.
  • the piston head 10 is cylindrical and is provided with annular grooves 11 along its outer periphery.
  • the piston head 10 is followed in the figure upwards (out of the plane of the paper) by the piston shaft 20, which has a cavity 25.
  • the piston shaft 20 must, as in the present case, have no circular cylindrical shape.
  • the piston stem comprises 20 recessed walls, so that the piston shaft 20 approaches a box shape.
  • two opposite pin holes 26 are provided for receiving a bolt.
  • the bolt holes are reinforced with bolt flanges 27.
  • bolt holes 26 may, as it is not shown in the figure, be equipped with a locking ring which is formed in a groove formed in the pin bore 26.
  • a bolt not shown in the figure, which serves as an axis for the small connecting rod eye of a connecting rod (not shown) superimposed.
  • the cavity 25 of the piston 1 is formed so that the connecting rod by an amplitude which is predetermined by the stroke of the piston 1, the connecting rod and the crankshaft, can rotate.
  • Two support ribs 30 extend parallel to the pin axis, which is predetermined by the two pin holes 26.
  • the two support ribs are provided symmetrically on both sides of the pin, not shown, and connect the opposite flattened sides of the piston skirt 20.
  • the ribs 30 are flat and have upper edges 31. Such an upper edge 31 of the support ribs, as implemented in the present embodiment, may be disposed above the centerline of the bolt axis.
  • the upper edge 31 of the support ribs 30 is arranged parallel to the pin axis and parallel to the piston head 12. It may be necessary by casting process, that the ribs 30 are formed double cone-shaped, the parallelism is thus only indicated and the edge 31 bulges in particular in the region of their connection to the piston shaft 20 to the outside.
  • the support ribs 30, which are substantially flat except for the connection region with the piston skirt 20, have cutouts 32.
  • two parallel support ribs 30 must be provided.
  • a support rib may be provided which connects the two flanges 27.
  • additional support ribs in addition to the two parallel support ribs, for example a support rib connecting the two flanges centrally and below the pin bores.
  • the recesses can be made smaller or larger in terms of weight optimization and / or structural stiffness optimization.
