Definitions
- the invention relates to a piston for an internal combustion engine according to the preamble of claim 1.
- Piston is e.g. B. from JP-GM 60-125338 known.
- Sheet metal resiliently against the inner hub approaches.
- Such attachment of Sheet metal requires complex shaping of the sheet metal.
- the invention is therefore concerned with the problem of a generic piston for an internal combustion engine the mounting of the sheet on the piston in a simple manner and To achieve wise and without complex shaping of the sheet.
- the grub screw can be used via an Allen key or serration or be turned a slot.
- a pressure piece can also be used, the - with the help of a device - biased Sheet is pushed through an opening in the sheet and that the bias of the when removing the device Sheet metal largely maintained.
- a piston upper part 1 of a pendulum-shaft piston has one Piston plate 2 and an outer cooling channel 3 below it and an inner cold room 4.
- the cooling channel 3 and the Cold room 4 are down through a sheet 5 and 6 respectively limited.
- the sheet is fixed 6 on the upper piston part 1 in that the sheet of one against the piston crown 2 supporting pressure screw 7 pressed down and so against existing on the upper piston part 1 Supports is clamped.
- Connected to the sheet - e.g. B. by pressure welding - is a nut 8, in which the Pressure screw 7 is screwed in.
- the sheet 6 is formed by Lugs 9, which run against the hub support of the piston, secured against twisting.
- the plate 6 is first exactly in the piston positioned and then the sheet is rotated the screw 7 is elastically deformed and preloaded as soon as the screw 7 is supported on the piston crown 2.
- the bracing takes place of the sheet against the piston crown by not tightening a screw or a set screw, but the sheet is pre-tensioned using a tensioning device and then is the pressure piece 7 'by an existing in the sheet Opening pushed through and rotated by 90 °.
- Sheet metal means - in particular further openings - available, which allow the clamping device to grip the sheet metal.
- the pressure piece 7 ' has a round in its upper region Cross-section, in its lower area it is narrow and elongated so that it is a total of a "screwdriver bit" similar.
- the sheet can by a Tilting movement can be positioned in the inner cold room.
