Definitions
- the invention relates to a piston for an internal combustion engine according to the preamble of the claim.
- a piston for an internal combustion engine with a base body made of aluminum and an annular element arranged in the radially outer edge region of the piston head and which forms an annular cooling channel with the base body is known from US Pat. No. 2,772,933.
- the ring element consists of an iron alloy, which has the disadvantage that the ring element makes a significant contribution to increasing the piston weight.
- the object of the invention is to avoid this disadvantage.
- the task is solved with the characteristics of the main claim.
- a useful embodiment of the invention is the subject of the dependent claim.
- the ring element made of aluminum according to the invention with a ring carrier made of NiResist for a compression ring combines the advantage of reducing the piston weight with the advantage of offering a wear-resistant bearing for the compression ring and thus increasing the load capacity and the service life of the piston.
- FIG. 1 shows a piston for an internal combustion engine with an aluminum ring element according to the invention in a sectional view consisting of two halves, which shows two longitudinal sections of the piston offset by 90 °, and
- Fig. 2 is an enlarged view of the section through the edge region of the piston crown with the ring element.
- 1 shows a piston 1 for an internal combustion engine in a sectional view consisting 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 section through the piston offset by 90 ° 1 shows.
- the piston 1 consists of an essentially cylindrical base body 4, one end face of which forms the piston head 5.
- a ring element 6 is arranged in the radially outer region of the piston crown 5.
- a combustion chamber 7 is formed in the central area of the piston crown 5.
- the base body 4 has, on its underside facing away from the piston crown 5, pin bosses 8 for the hub bores 3 and the pin bosses 8 connecting shaft elements 9.
- the ring element 6 has on its radially outer lateral surface 10 a ring carrier 11 for a compression ring (not shown in the figure) and below it a second ring groove 12.
- An oil ring groove 14 is arranged below the second ring groove 12 in the lateral surface 13 of the base body 4.
- the ring element 6 is fastened on the base body 4 via a screw connection, in which the ring element 6 is screwed onto an external thread 18 via an internal thread 19, which is located on the radially inner side of the ring element 6, which thread is on an axially aligned region 23 the lateral surface 13 is arranged, which adjoins the piston crown 5 and is set back in the direction of the piston longitudinal axis 17.
- the radially inner side of the ring element 6 has at its lower end facing away from the piston crown 5 a recess 20 which forms an annular cooling channel 22 with a recess 21 formed in the lower end of the recessed jacket region 23 on the piston crown side. Cooling oil is introduced into the cooling duct 22 via channels not shown in the figure and is discharged again from the cooling duct 22.
- the end of the screw connection 18, 19 on the piston bottom side is connected by means of a Sealed weld 24, which can be produced, for example, with the electron beam welding process.
- the piston 1 consisting of the base body 4 and the ring element 6 is made of aluminum, the base body 4 being given the desired shape by forging, whereas the ring element 6 is produced in a casting process.
- the ring carrier 11 consisting of NiResist (austenitic cast iron with components of Ni, Mn, Cu and Cr) is cast into the ring element 6 in the composite casting process.
- the piston 1 is given the final shape by a machining production process, for example by turning.
- the section shown in FIG. 2 through the edge region of the piston 1 on the piston-bottom side shows the ring element 6 with the cast-in ring carrier 11, which is connected to the base body 4 via the screw connection consisting of the internal thread 19 and the external thread 18.
- the weld seam 24 used to seal the screw connection 18, 19 can be clearly seen.
