Definitions
- the invention relates to pistons for an internal combustion engine with an upper part, whose upper side forms the piston crown, with a radially outwardly formed on the piston head, pointing downwards in kolbenêtabgewandte direction, circumferential collar, on the radial outer side of a Verdichtungsringnut is arranged with one on the underside the upper part arranged radially inside the collar, circumferential annular rib, wherein the axial length of the collar is smaller than the distance of the lower end face of the annular rib from the piston head, with a lower part, which has radially outwardly an upwardly facing, circumferential wall, in the radial outer side Ring grooves are formed, and whose upper end face has the same radial distance from the piston axis as the lower end face of the collar, with an integrally formed on the lower part, upwardly facing, circumferential and radially disposed within the wall pad, the upper end face of the piston axis the has the same distance as the lower end face of
- a piston of the aforementioned type is known from PCT application WO 02/33291.
- This piston has a close to the bottom of the cooling chamber and the cooling channel arranged oil passage, which connects the cooling chamber with the cooling channel, and in particular prevents the formation of ⁇ iesammiung in Riehiraum and thus deteriorates the cooling of the thermally highly loaded piston crown, because the oil in the refrigerator can flow back into the cooling channel via the oil passage, and only then oil flows from the cooling passage into the cooling space when the oil level of the oil in the cooling passage is higher than the level of the oil in the cooling space. This also obstructs the flow of oil from the cooling channel through the cooling chamber to the oil drain opening, which reduces the flow of cool oil and thus leads to a further deterioration of the cooling of the piston crown.
- Object of the present invention is to avoid this disadvantage of the prior art, and to improve the cooling of the thermally high-stress piston crown.
- This object is achieved in that evenly distributed over the circumference, radially disposed bores are introduced into the annular rib, which connect the cooling channel with the cooling space, which are spaced from the lower end face of the annular rib insofar as between the holes and the end face of the annular rib there is sufficient space for a weld bead formed during friction welding and axially spaced from a plane defined by the lower end face of the collar, that the web has an upwardly tapered shape, and at least one oil inlet opening between the cooling passage and the piston inner space is arranged.
- the spaced from the bottom of the cooling chamber position of the bores between the cooling channel and the cooling space and the upwardly tapered shape of the web, which forms the lower boundary of the refrigerator, in the radially outer region of the refrigerator allows the formation of ⁇ mansammiung that in the fast Reciprocating movements of the piston in engine operation to a good cooling of the thermally highly loaded piston crown leads by the oil of ⁇ mansammiung in At regular intervals on the underside of the piston crown is thrown.
- the opening of the web is closed by an upwardly curved disc with a centrally located opening which is connected via a latching connection with the web, whereby the assembly of the piston is facilitated.
- Fig. 1 the upper part and the lower part of a two-part piston for an internal combustion engine before mounting in section and
- Fig. 2 is a two-half sectional view of the piston, wherein the left half shows a section along the pin bore axis, and the right half shows a section perpendicular to the pin bore axis.
- Fig. 1 and 2 show an existing of an upper part 1 and a lower part 2 piston 3 for an internal combustion engine in section, the sectional images in each case from approximately axis 4, whereas the right halves of the sectional images are perpendicular to the pin bore axis 4.
- the upper part 1 made of steel has on its upper side a piston bottom 5 with a combustion bowl 6.
- a circumferential, downwardly facing collar 7 is integrally formed on the piston head 5, which defines a peripheral recess 8 radially outward, which forms the upper part of a radially outwardly and in piston crown near cooling channel 9 in the finished piston 3 as shown in FIG.
- the collar 7 On its radial outer side, the collar 7 provides space for a top land 10 and a compression ring groove 11.
- the upper part 1 on its side facing away from the piston bottom 5 a circumferential annular rib 12, which forms the radially inner boundary of the upper part of the cooling channel 9 and the radially outer boundary of the upper part 13 of a centrally located Riehiraums 1 4, in the annular rib 1 2 Distributed uniformly over the circumference, radially located bores 1 5 introduced that connect the cooling channel 9 with the cooling chamber 1 4 in the assembled piston 3 as shown in FIG.
- the piston 3 four holes 1 5 on. These holes 1 5 may have the inwardly and outwardly flared shape of a mold bore.
- the axial length "a" of the collar 7 is smaller than the distance "b" of the lower end face 16 of FIG Ring rib 12 from the piston head 5, resulting from the diameter "d” of the holes 1 5, a distance "s” of the holes 1 5 of the lower end face 16 of the annular rib 1 2 and an axial distance “c” of the holes 15 from the lower End face 1 7 of the collar 7 composed.
- the distance "c” should ensure that the drill when inserting the holes 1 5 relative to the collar 7 has sufficient space.
- the distance "s" of the holes 1 5 of the lower end face 1 6 of the annular rib 12 corresponds to the axial dimension of the welding bead 1 8, which forms when the upper part 1 and the lower part 2 by friction welding mi + oinfinHür ⁇ hot nrl "c" cnll WörhinHoH '/ orHon that the welding bead 18 passes during welding of the upper part 1 with the lower part 2 in the region of the holes 1 5 and thus obstructs the flow of cooling oil through the holes 1 5.
- the also made of steel lower part 2 of the piston 3 consists of a bottom member 19, on the piston bottom facing upper side radially outwardly a circumferential wall 20 is arranged, in the radially outer annular grooves 21, 22 are formed.
- the upper end surface 23 of the wall 20 has the same distance from the piston axis 24 as the lower end face 1 7 of the collar 7, so that the end faces 7 and 23 during welding of the upper part 1 with the lower part 2 Reibsch hassle-
- the wall 20 is adjoined by a peripheral support 25 which is at the same distance from the piston axis 24 as the annular rib 12 and whose upper end surface 26 has an axial distance from the plane formed by the end face 23 of the wall 20 corresponds to the dimension (c + d + s), to which the distance "a" of the end face 17 of the collar 7 from the piston head 5 is less than the distance "b" of the end face 16 of the annular rib 12 from the piston head 5. It follows that when welding the upper part 1 with the lower part 2, not only the end faces 17 and 23 but also the end faces 16 and 26 Reibsch do lake form.
- a circumferential recess 27 is formed in the bottom element 19, which forms the lower part of the cooling channel 9 in the assembled piston 3 according to FIG.
- the bottom member 9 is formed as a circumferential, upwardly tapered web 28 having a centrally located, circular opening 29, wherein the region 38 formed between the web 28 and the support 25 as a circumferential and upwardly open channel is.
- the cooling space 14 is bounded at the top by the piston head 5, radially outwardly by the annular rib 12 and by the support 25 and at the bottom by the web 28.
- the edge 32 of the opening 29 of the web 28 ( Figure 1) has the shape of a radially inwardly open "V" in section, which makes it possible to form a cup-shaped, upwardly curved disk 30 with a centrally located opening 31, with an outer dimension corresponding to the inner dimension of the opening 29, and with a radially outer edge which is complementary to the edge 32 of the opening 29, to be fastened in the opening 29 by means of a latching connection.
- the edge of the disc 30 identifies the required compliance, radial slots 33 are incorporated into the edge, where between the edge of the disc 30 is formed in the form of elastically resilient metal tabs. This makes it possible to press the disc 30 from below into the opening 29 of the web 28 after the completion of the piston 3 and to fix it via the resulting latching connection.
- the cooling passage 9 is connected to the piston interior 35. Furthermore, 19 are two on the underside of the bottom element opposite shaft elements 36, 36 'are arranged, which are connected to each other via two mutually opposite pin bosses 37, 37', each with a pin bore 39, 39 '.
- cooling oil is introduced into the cooling channel 9 via the oil inlet opening 34, which due to the rapid reciprocating movements of the piston 3 to the underside of the radially outer region of the piston crown 5 and the part of the formed by the wall 20 and the collar 7 Piston 3 is thrown and here it has a cooling effect.
- (Shaker effect) A portion of the oil passes through the holes 15 in the cooling chamber 14, wherein in the radially outer portion 38 of the cooling chamber 14 an accumulation of oil forms, which remains because of the spaced from the bottom member 19 position of the bore 15 in the cooling space 14, to the Bottom of the piston head 5 is thrown in the region of the thermally highly loaded combustion bowl 6 and here cooling acts. A portion of this oil then passes through the opening 31 of the disc 30 in the Koibeninnenraum 35th
