Definitions
- the invention relates to a one-piece piston for an internal combustion engine according to the preamble of claim 1.
- a multi-part cooled piston with a cooling channel arranged in the edge region of the piston head is known, which is covered with a sheet-metal ring which is essentially shaped like a plate spring.
- This sheet metal ring is made in one piece and can only be easily fitted to the piston because the piston is constructed in two parts. It is necessary to first mount the sheet metal ring on the upper piston part before it is connected to the lower piston part.
- the invention is based on the problem of creating an easy-to-install cooling duct cover for a one-piece piston of an internal combustion engine.
- FIG. 1 shows a piston for an internal combustion engine with a cooling channel, which according to the invention is closed by an essentially cylindrical ring, shown in a sectional view consisting of two halves, showing two longitudinal sections of the piston offset by 90 °,
- FIG. 2 shows a section of the piston along the line A-A in FIG. 1,
- FIG. 3 shows a partial section of the piston along the line C-C in FIG. 2, which shows an oil feed pipe for introducing cooling oil into the cooling channel,
- FIG. 4 shows a partial section of the piston along the line B-B in FIG. 2, which shows the oil feed pipe which is locked with the ring,
- FIG. 5 is an enlarged view of the area "X" in Fig. 4, which shows the latching connection between the ring and the oil supply pipe,
- Fig. 6 is a plan view of the ring with the oil supply pipe and
- Fig. 7 is a perspective view of the ring with the oil supply pipe.
- Figure 1 shows a one-piece piston 1 for an internal combustion engine in a sectional view, which consists of two halves, of which the left half is a section of the piston 1 along a longitudinal axis 2 of a hub bore 3 and the right half is a longitudinal section of the staggered by 90 ° Piston 1 represents.
- the piston 1 is made of steel and has a combustion chamber trough 5 in the region of the piston crown 4.
- Arranged in the radially outer region of the piston crown 4 is an annular circumferential cooling channel 6, the radially outer boundary of which is formed by an annular wall 7 formed on the piston crown 4 and the radially inner boundary partly by an annular rib 8, partly by a hub support 9, 9 'and partly are formed by a shaft connection 10, 10 '.
- the ring wall 7 serves as a piston ring carrier.
- a pin hub 11, 11 ' each with a hub bore 3, 3', is formed on the piston head 4 via the hub supports 9, 9 '.
- a circumferential, nose-shaped projection 17 is attached, the purpose of which is to serve as a system for a substantially cylindrical, one-piece ring 18, of which the Cooling channel 6 is closed.
- the ring 18 can be made of plastic or metal.
- the ring wall 7 On the inner side 28 facing the piston longitudinal axis 13, the ring wall 7 has a circumferential groove 19 into which a collar 20, which is also circumferential and is formed on the piston bottom side on the outside of the ring 18, can be inserted, as a result of which the ring 18 can be fastened to the inside of the ring wall 7. As shown in FIGS. 6 and 7 in particular, the ring 18 has a gap 22.
- the ring 18 can be assembled in a simple manner by bending it and inserting it into the area of the piston 1 between the ring wall 7 and the shaft elements 14, 14 '. Subsequently, the ring 18 is compressed, so that its radius is reduced, the lower edge of the ring 18 on the shaft side coming to rest on the projection 17. Because the upper edge of the ring 18 on the piston bottom side is pressed a little more inward, it is then possible to push the ring into the cooling channel 6 from below until the ring 18 has its collar 20 in fixed the groove 19 engages on the inside 28 of the ring wall 7.
- an oil supply pipe 35 can be inserted, which consists of a funnel 21 with a tubular upper part 27, and which spreads the ring 18 when inserted.
- the oil supply pipe 35 can be made of plastic or metal.
- the oil supply pipe 35 is fastened to the piston 1 by a lug 23 attached to the upper part 27 resting on the upper edge of an opening 24 made near the shaft 14, 14 'after the Oil supply pipe 35 is inserted into the opening 24.
- the upper part 27, as shown in FIGS. 4, 5 and 7, has a circumferential groove 25 on its outer side facing the piston crown, into which the oil supply pipe 35 is inserted into the opening 24 on the inner side of the ring 18 at its abutment points 29 and clip in 30 molded projections 26, 26 ', thereby securing the oil supply pipe 35 to the ring 18.
- the groove 25 is at a certain distance from the end face 33 of the upper part 27 on the piston crown side, which is sufficient that, as shown in FIGS. 5 and 7, there is a protrusion 34 of the upper part 27, so that the oil introduced into the cooling channel 6 does not immediately flow out of the cooling channel 6 again through the upper part 27 and instead is led around the overhang 34 into the lower-lying region of the cooling channel 6.
- the cooling oil can then flow off through an opening 36 in the side of the ring 18 (FIG. 7).
