Definitions

  • the invention relates to a piston, in particular a cooling channel piston, an internal combustion engine according to the features of the preamble of patent claim 1.
  • an internal combustion engine which consists of exactly two parts. These parts are an upper part, which here has a radially encircling ring field and a combustion bowl. As a further part, a lower part is provided, which receives the piston skirt and the pin bore. At the lower edge of the ring field and at the deepest vertex of the combustion chamber trough radially two circumferential joining webs are present on the upper part, which correspond in position and extent with two joint webs of the lower part.
  • These two separately producible parts are inseparably connected to each other by means of a joining process, which is a friction welding process. Thereafter, a one-piece cooling channel piston is available, which can be installed in the internal combustion engine, optionally after it has been finished.
  • both the upper part and the lower part are designed in such a way that they form, together with the mutually corresponding joints after the joining process, a cooling channel lying behind the annular field for the circulation of cooling medium.
  • a cooling channel lying behind the annular field for the circulation of cooling medium.
  • both the upper part and the lower part have at least three radially surrounding joining webs.
  • two joining webs of the upper part and the lower part are arranged coaxially within four joining webs, so that the upper part with the lower part not only two joining areas, as it was previously known, but three (or possibly even more) joint areas are interconnected.
  • This also increases the long-term stability over the life of the piston during its operation in the internal combustion engine.
  • the support of the combustion chamber trough is improved, in particular stiffened, by the further joining steps, so that the material thickness in the region of the combustion chamber trough can be reduced, which leads to weight spatter.
  • the invention provides that the upper part and the lower part are designed such that they form a further cooling channel with the further joining webs.
  • the cooling channel piston not only has a cooling channel lying almost directly behind the annular field, but also at least one further cooling channel within which a cooling medium (in particular engine oil) can circulate, around the piston head (in particular the region below the combustion chamber trough) ) to be able to cool.
  • a cooling medium in particular engine oil
  • three cooling areas can be created, which is an outer and a middle cooling channel and the third area is below the apex of the combustion bowl.
  • the joining webs in three different joint areas have approximately the same cross-section. As a result, a nearly equal structural strength is achieved within the piston crown.
  • the almost same cross-section also has an advantageous effect on the joining process, since always the same amounts of energy applied and not consuming coordinated with each other.
  • the joining process is, in a particularly advantageous manner, a friction welding process, since this makes it possible to work all three joint areas simultaneously and thus to non-releasably connect the upper part to the lower part.
  • the use of only two parts (upper part and lower part) for the production of the cooling channel piston still leads to a reduction in the variety of parts, which is especially important in the series production of pistons.
  • the top and bottom can be made in the same or different processes (such as forging, casting, pressing, extrusion, and the like) and made of the same or different materials.
  • the upper part may be made of a more heat-resistant material than the lower part. Weight aspects also play a role here.
  • the upper part may consist of a lightweight material (such as aluminum), while the lower part consists of an iron material (for example gray cast iron).
  • FIG. 1 shows a first exemplary embodiment with approximately three identical friction-welded cross-sections
  • FIG. 2 shows a second exemplary embodiment with different friction-welded cross sections and different joining planes
  • FIG. 3 shows a third exemplary embodiment with virtually identical friction-welded cross sections in different joining planes
  • Figure 4 shows a fourth embodiment with almost the same Reibsch spaquerroughen and three different joining planes, wherein three cooling areas are formed.
  • FIG. 1 shows a cooling channel piston which has an upper part 2 and a lower part 3.
  • the upper part 2 has in known manner a combustion bowl 4 and a radially encircling ring field 5 with unspecified annular grooves.
  • the lower part 3 is added, which in turn has a Bolzenboh- tion 6 and a piston shaft 7.
  • the upper part 2 is in particular connected to the lower part 3 with a friction welding process in three joining regions 8 to 10.
  • a joining web 11 of the upper part 2 and a joining web 12 of the lower part 3 are opposite.
  • a joining web 13 of the upper part 2 and a joining web 14 of the lower part 3 are opposite.
  • a joining web 15 of the upper part 2 and a joining web 16 of the lower part 3 are arranged.
  • the first joining region 11 is in a first joining plane 17 and the second joining regions 9, 10 are both arranged in a second joining plane 18.
  • the upper part 2 and the lower part 13 are designed so that they form a lying behind the ring field 5 cooling channel 19 with their radially surrounding joining webs 11.
  • FIG. 2 shows the cooling channel piston 1, which likewise has three joining regions 8 to 10 with associated joining webs 11 to 16.
  • the first joining region 8 is located approximately below the annular field 5, while the second joining region 9 is present approximately at the lowest vertex of the combustion chamber trough 4.
  • the third joining region 10 with its mutually opposite joining webs 15, 16 on the Motion axis of the stroke of the cooling channel piston 1 is arranged during its operation.
  • This leads to the cooling channel 19 already described in FIG. 1, while here, due to the design of the upper part 2 and the lower part 3 with the joining webs 13 to 16, a further cooling channel 21 lying coaxially behind the cooling channel 19 is created.
  • the openings for the supply and the flow of the circulating in the cooling channel 19, 21 cooling medium are present, but omitted here for the sake of clarity (as well as in the other figures).
  • the joining webs 11 to 17 have different cross-sections and lie in different joint planes 17, 18, 20.
  • FIG. 3 shows the cooling channel piston 1, in which also three joining regions 8 to 10 are present, wherein the joining webs 11 to 16 have almost the same cross-section, but in three different joining planes 17, 18, 20 are arranged. Again, two cooling channels 19, 21 are available again.
  • FIG. 4 shows the cooling channel piston 1 with three joining regions 8 to 10 and the associated joining webs 11 to 16, wherein the joining webs have almost the same cross section but are arranged (stepped) in three mutually different joining planes 17, 18, 20. Due to the design of the lower part 2 not only two cooling channels 19, 21 are formed, but it is in the inner region 22 (which extends below the upper vertex of the combustion bowl 4) realized another closed space, which can also act as a cooling area.
  • cooling channels can also be cavities, which are not flowed through by a cooling medium but serve to save weight in the region of the upper part (piston crown).
  • the invention is equally applicable to one-piece pistons (as shown in the embodiments, wherein the finished one-piece piston from the top and the bottom is joined together) as well as in finished multi-part piston (in particular pendulum stock piston). LIST OF REFERENCE NUMBERS
  • First joining plane 20 18. Second joining plane
