Definitions
- the invention relates to a ring carrier for a piston of an internal combustion engine with a sheet metal cooling duct, the is connected to the ring carrier by welding.
- Ring carrier-cooling channel combinations are in themselves e.g. out known from US 4,907,545 or from FR 2,044,242. At These constructions are the ring carrier back for formation profiled a cooling channel so that a relatively simple, circular or cylindrical sheet the cooling channel can close. However, this requires a lot of material and processing and increases compared to a U-shaped sheet metal cooling channel, the weight of the piston.
- JP-OS 5-240347 it is also known to im Cross section approximately C-shaped, circular sheet metal cooling channel in shrink the ring carrier and weld it to it.
- This sheet metal part can only be made by complex Manufacture metal forming technology.
- the invention is therefore concerned with the problem of a generic ring carrier a complex and expensive Avoid shaping the sheet metal cooling channel or the ring carrier.
- the radially outer wall of the sheet metal cooling duct can both be formed by one as well as by both sheet metal parts or the radial outer boundary of the cooling channel can formed by the radially inner wall of the ring carrier be.
- the weld seam is usually in the radially inner one Wall of the sheet metal cooling duct.
- Sheet metal cooling duct By dividing the sheet metal cooling duct into two duct halves it becomes possible instead of a part that is difficult to manufacture two simple parts to use. Another advantage of Sheet metal cooling duct according to the invention is possible a variable shape with uneven cross-sections about the extent that z. B. positioned off-center Troughs may be required.
- Ring carrier that shrinking the sheet into the ring carrier or the bending around known from DE-OS 26 24 412 of the sheet around the ring carrier can be omitted.
- the two sheet metal parts can, for. B. as circular half-shells be formed - with a side wall of the half-shell is pulled up - as in Fig. 1 or it can be a sheet metal part as a half-shell and the second sheet metal part with an annular shape Angular profile as in Fig. 2 be formed.
- the two halves of the cooling duct are usually together welded.
- the parts of the sheet metal cooling channel in the Groove reinforcement pressed in and in addition can a ring carrier Centering or on the ring carrier back shoulders be in contact with the sheet metal part.
- the piston 1 has a cooled ring carrier 2, the from a solid, circular groove reinforcement 3 made of Niresist material and one welded to the groove reinforcement 3 Sheet metal cooling duct 4, which in turn consists of 2 together welded channel halves 5 and 6.
- the radially outer boundary of the cooling channel is due to the radially inner wall of the groove reinforcement 3 is formed.
