Definitions

  • the invention relates to a piston ring, comprising a base body having a tread provided with a chamber, an upper and a lower flank surface and an inner peripheral surface.
  • EP-A 1 482 075 describes a piston ring coating which is formed by tungsten disulfide.
  • a well-known way to produce relatively sharp running edges on coated rings is the use of full or one-sided chambered rings. Disadvantage of these rings is that a certain part of the tread is inherently not provided with a protective coating and it comes in this area, in which then comes the grandmother material into contact with the cylinder, often to so-called scorching.
  • the invention has for its object to further develop a piston ring to the effect that the said disadvantages are no longer given to optimize the oil balance using a provided with at least one chamber tread.
  • a piston ring having a base body which has a running surface provided with a chambering, an upper and a lower flank surface and an inner circumferential surface, wherein at least the chambering is provided with at least one wear protection layer and at least partially a PVD on the running surface Cover layer is applied, such that the base body in its finished state only edge region side, d. H. outside the chamber, the PVD cover layer has.
  • PVD Physical Vapor Deposition
  • one-sided or fully chambered piston rings made of cast iron or steel materials can be provided with a galvanically or thermally applied wear protection layer.
  • the respective edge region ie outside the chamber, should be provided with the PVD cover layer. This can be achieved by either only the edge areas are provided with the PVD cover layer, or the entire tread including Kamm réelle coated with a PVD cover layer and then the PVD cover layer in the chamber, z. B. by grinding, is removed.
  • the PVD layer can be formed on the basis of nitrides of the elements of group IV b to VI b of the periodic table.
  • the following elements may be added singly or in combination: Al, Si, C, O.
  • PVD DLC diamond-like-carbon
  • Figure 1 piston ring in cross-section, which is provided on the tread side with a chamber on which a PVD cover layer is deposited;
  • FIG. 2 piston ring according to FIG. 1 with the cover layer partially removed;
  • FIG. 1 shows a piston ring 1 which has a basic body of rectangular cross section, including a running surface 2, an upper 3 and a lower flank surface 4 and an inner circumferential surface 5.
  • the running surface 2 is provided with a chamber 6 into which a wear protection layer 7, for example, chromium, is introduced.
  • a wear protection layer 7, for example, chromium is introduced.
  • a PVD covering layer 8 made of CrN is deposited, which in this example should have a thickness of 8 ⁇ m.
  • Alternative materials, such as CrON are also conceivable as a PVD cover layer.
  • FIG. 2 shows the finished state of the piston ring 1. It can be seen that the chamber 6, or the wear protection layer 7 given there, is freed from the PVD covering layer 8 according to FIG. This was achieved by partial grinding of the PVD covering layer 8 in the area of the chambering 6. Thus, only the edge areas 9, 10 remain covered with the PVD covering layer 8. Since these edge regions 9, 10 protrude radially with respect to the wear protection layer 7, an oil reservoir is initially formed, which is advantageous for the running-in behavior of the piston ring 1.
  • FIG 3 shows an alternative to Figure 1.
  • the piston ring 1 'shown here also includes a chamber 6', in which a wear protection layer T is introduced.
  • a wear protection layer T is introduced.
  • only the edge regions 9 ', 10' are provided outside the chamber 6 'with a PVD cover layer 8'.

Abstract

Segment de piston avec un corps de base qui présente une face de portée (2) pourvue d'une chambre (6, 6'), une face de flanc supérieure (3), une face de flanc inférieure (4) et une face périphérique intérieure (5). Au moins la chambre est pourvue d'une couche (7, 7') de protection contre l'usure. De plus, une couche de recouvrement (8, 8') déposée en phase gazeuse est appliquée au moins partiellement sur la face de portée de telle sorte que le corps de base, dans l'état achevé, présente la couche de recouvrement uniquement dans les régions de bords (9, 10, 9', 10'), c'est-à-dire en dehors de la chambre.
