Definitions
- the invention relates to a piston for an internal combustion engine according to the preamble of claim 1.
- Such a piston is known from DE 19547157 A.
- various options are disclosed, for. B. screwing, shrinking, welding.
- the invention is therefore concerned with the problem of finding a fastening possibility for the shaft or the support ring in the case of generic pistons which does not lead to a distortion in the hub area and which is easy to produce.
- the attachment of the support ring in the manner of a bayonet lock results in a central positioning relative to the hub.
- the connection is largely free of tension and can be released.
- Bayonet lock in this context is to be understood that the shaft or the support ring after the is placed on the hubs in the axial direction by turning in the circumferential direction, in which either inward-pointing projections of the shaft engage in grooves in the hubs or projections on the hubs engage in grooves in the shaft. The shaft is thus secured against axial displacement.
- the support ring or the shaft is mounted on the hubs by the support ring in a position that allows it to be pushed onto the hubs - in which the hubs and the areas with a larger inner diameter are aligned on the support ring - up to the level of the outer surface of the hub in 2 and then - in an embodiment according to FIG. 2 - is rotated by approximately o 30, so that, as shown in FIG. 2, those regions of the support ring which have a smaller inner diameter are in the circumferential grooves to grab.
- the support ring or the shaft can then be secured against rotation in the circumferential direction by one or more clamping sleeves.
- FIG. 2 shows a cross section at the level of the hub axis.
- a piston 1 consists of a piston head 2 made of forged steel and hubs 3 emanating from the piston head and ring grooves 4, 5 and 6 which are penetrated radially into the piston head, each for receiving a piston ring.
- the hubs 3 have bores 7 for receiving a piston pin.
- a groove 8 is inserted into the hubs, the groove extending only over a few angular degrees, approximately 15-30 degrees for each pierced outer surface of the hub, corresponding to the dashed areas in FIG. 2.
- Both hubs are pierced on the pressure and counter pressure sides, so that the groove or grooves, added up over all four surfaces, has an angular range of approx. 60-120 degrees.
- a support ring 9 fastened directly on the hubs in the manner of a bayonet lock.
- the support ring 9 has different inner diameters, the larger inner diameter present in the region of the recesses 10 being dimensioned such that the support ring 9 can be pushed onto the hubs 3 from below and the smaller inner diameter approximately the groove base diameter of the in corresponds to the hub grooves. o In Fig. 2, the support ring 9 is mounted rotated by about 30.
- the height of the groove 8 corresponds approximately to the height of the support ring 9, the axial play between the groove and the support ring generally being dimensioned such that the support ring 9 can be rotated by hand in the groove.
