Definitions
- the invention relates to a multi-part cooled piston for an internal combustion engine having a piston forged part made of steel, which comprises a combustion bowl in the piston crown and an annular wall with a ring section, and a piston lower part, which has a piston skirt, hubs for receiving the piston pin connecting the piston to the connecting rod, and with the piston skirt connected hub supports, wherein a cooling channel is formed by the upper piston part and lower piston part and its cross section is limited by this.
- a multi-part cooled piston for an internal combustion engine is known from JP 61175255 A.
- This piston shows a number of ribs at the level of the ring portion of the piston, between which a heat-insulating plate is arranged to minimize the heat transfer from the combustion chamber trough to the ring portion.
- WO 00/77379 A1 Another piston for an internal combustion engine is known from WO 00/77379 A1, which has a wall part with a plurality of radially arranged transverse walls made of thin sheet metal to improve the heat dissipation in the cooling channel.
- the invention is therefore based on the object of specifying a multi-part cooled piston which can be inexpensively manufactured with sufficient dimensional stability and a cooling system with improved cooling effect.
- a cooling channel formed in the upper piston part is distributed over its circumference and directed towards the piston crown. stanchions, the piston material present between the bores forming support ribs which form sections of a circumferential ring rib radially towards the longitudinal axis of the piston.
- a lower piston part has a ring-shaped circumferential supporting rib connected to the hub supports. The upper piston part and the lower piston part are inseparably connected to one another by means of the ring and support rib, the annular wall delimiting the cooling channel forming a gap with the lower piston part through its wall cross section, in which a sealing element can be arranged.
- the cooling channel can be shaped closer to the piston crown or combustion bowl and still has excellent dimensional stability.
- the arrangement of the support ribs results in a type of chamber formation in the cooling channel, i. H. Generation of shaker rooms, which extends the length of time the cooling oil stays and thus improves the heat dissipation of the piston areas to be cooled.
- Figure 1 shows a piston according to the invention in cross section, cut in the pin direction.
- FIG. 2 shows a piston according to the invention in a bottom view, cut along line II according to FIG. 1;
- FIG. 3 shows a piston according to the invention in cross section, cut transversely to the piston pin direction
- FIG. 4 shows a piston according to the invention, cut along the line IV-IV from FIG. 1;
- FIG. 5 shows a piston according to the invention in a perspective view
- the multi-part cooled piston 20 according to the invention consists of a forged upper piston part 1 with a combustion bowl 3, ring wall 4 with ring section 11 and an (upper, towards the piston crown) part of a cooling channel 7 and a lower piston part 2, one (lower, towards the piston skirt 9 ) Part of a cooling channel 7, a piston shaft 9 and hub supports 6, as shown in FIG. 5, comprises.
- 7 holes 14 are provided in the cooling channel, which are arranged symmetrically distributed on the circumference and are introduced in the direction of the piston crown, ie parallel to the longitudinal axis K of the piston.
- the depth hr_ of the bores is a maximum of half the total height H of the cooling channel 7, so that an unobstructed cooling oil circuit remains guaranteed. This construction creates shaker spaces for the cooling oil, which increase the cooling effect.
- the respective oil inlet and oil outlet are not shown in the figures.
- the material regions designated as support ribs 8 between the bores 14 merge radially to the longitudinal axis K of the piston into sections of an annular rib 5, which in its entirety forms the annular rib 5.
- the bores 14 and thus the support ribs 8 are, as shown in FIG. 4, distributed radially symmetrically over the circumference of the cooling channel 7.
- the distribution can be designed such that a larger number of bores 14 and thus support ribs 8 are arranged in the pressure-counterpressure direction D, GD of the piston 20 than transversely thereto, that is to say an asymmetrical circumferential distribution in the Cooling channel 7 takes place.
- the distribution of the bores 14 and thus the support ribs 8 in the cooling channel 7, if this is characterized according to the quadrants I-IV formed by the main piston axes K H , can be such that a symmetrical (FIG. 6) or asymmetrical distribution within a quadrant (not shown) is provided, which are in the opposite quadrants, ie I. and III. or II. and IV.
- the bores 14 can be aligned by round bores, as shown in FIGS. 4 and 6, or elongated bores (not shown), which have their long side in the direction from the center of the piston radially outward to the piston wall.
- the tips of the bores 14 can be round or, as shown in FIG. 1, angled.
- the axes of the bores 14 can, as shown in FIG. 1, parallel to the piston longitudinal axis K and / or, i. H. in combination, at an acute angle to it, the holes 14 pointing in the direction of the combustion bowl 3.
- annular circumferential supporting rib 10 is formed, as can be seen in FIG. 3, which corresponds in its geometric dimensions to the annular rib 5.
- the upper piston part 1 and lower piston part 2 are inseparably connected to one another via the supporting and ring ribs 10 and 5 by means of a welding or soldering process, with subsequent finishing of the piston 20 to a piston which can be used in an engine being carried out by means of machining.
- the upper piston part 1 advantageously consists of an oxidation-resistant and / or heat-resistant material and the lower piston part 2 consists of a precipitation-hardening ferritic-pearlitic steel or tempered steel.
- the outer piston wall regions between the two piston parts 1 and 2 form a bearing surface which is characterized by a gap 13 which is a few tenths of a millimeter wide.
- This can remain open or be sealed by means of a temperature-resistant sealing ring which is positioned on one of the bearing surfaces, for example that of the lower piston part 2, before the joining of both piston parts 1 and 2.
