Definitions

  • the invention relates to a channel for the distribution of lubricating oil in a piston internal combustion engine according to the preamble of claim 1.
  • the lubricating oil conditioned in the filter and oil cooler is supplied to various consumption points via the channel and through branch bores running in the transverse walls.
  • Each channel section comprises two flange-like connecting parts fastened by screws, each with a sleeve and a tube which can be inserted sealingly into the sleeves of the two associated connecting parts. Sealing surfaces for the connection parts are formed around the mouths of the transverse wall passages of the channel.
  • crankcase in the region of the channel by the design of the components for the channel sections between the transverse walls.
  • the advantages achieved by the invention are, in particular, that there is a reduction in the manufacturing costs of the crankcase, that the weight and number of components of a duct section to be mounted between two transverse walls are reduced, that there are low manufacturing costs for socket and plug-in pipe, and that assembly and Disassembly of the components of the channel section can be carried out quickly and easily.
  • a channel serving to distribute lubricating oil extends in the longitudinal direction of a piston internal combustion engine through a plurality of transverse walls 11, 12 of the crankcase 13, which is only partially shown.
  • the transverse wall passages 14, 15 of the channel are designed as bores, from which branch holes 16, 17 depart, which the lubricating oil different consumption points, for. B. the crankshaft bearings 18, 19.
  • the channel is formed from two axially joined components, which are sealed to one another and to the transverse wall passages 14, 15.
  • the channel-forming components used between the transverse walls 11, 12 consist of a plug-in tube 23 and a socket tube 24 which receives the plug-in tube 23 in a sleeve 25 and which can be axially displaced relative to one another in the installed state.
  • the mouth of the sleeve 25 is designed as a radially slotted clamp 26 with a screw as a clamping device 27.
  • a radial groove for receiving a sealing ring 20, 21, 22 is arranged on the outer circumference of the free ends of the plug-in pipe 23 and the socket pipe 24 as well as on the end of the plug-in pipe 23 inserted in the socket 25.
  • the three radial grooves advantageously have the same dimensions, so that only a single size of the sealing ring is required.
  • the wall 28 of the sleeve 25 is axially adjacent to the clamp 26 located at the mouth of the sleeve 25 with two diametrically opposite openings 29, 30. Furthermore, two adjacent circumferential grooves 31, 32 are formed on the outer circumference in the middle part of the plug-in tube 23, which are located axially in relation to the openings 29, 30 in the wall 28 of the sleeve 25 and to the tensioning device 27 of the clamp 26.
  • the plug-in tube 23 is pushed into the sleeve tube 24 up to the stop on the base 37 of the sleeve 25.
  • the overall length of the parts joined into one another is shortened to such an extent that they can be inserted with axial play between the transverse walls 11, 12 (see FIG. 1a).
  • the plug-in pipe 23 and the socket pipe 24 are in the aligned position with the drilled transverse wall passages 14, 15, the plug-in pipe is made with the aid of a tool which is supported through the openings 29, 30 in the visible circumferential groove 32 and on the end face of the clamp clip 26 23 pushed out of the sleeve 25.
  • the circumferential groove 32 reaches the edge of the openings 29, 30 in the region of the clamp 26.
  • the tool is then moved so that it is now accessible in the second adjacent circumferential groove 31, which is in the openings 29, 30 has become supported.
  • the second sliding stroke of the plug-in pipe 23 is ended when the conical shoulders 34 formed on the free ends of the plug-in and socket pipe 23, 24 face the conical extensions 33 of the transverse wall passages 14, 15 with a small distance.
  • the screw can be screwed into the clamp 26 and tightened.
  • the clamp 26 is thereby clamped on the plug pipe 23, so that there is no longer any axial displacement between the plug and socket pipe 23, 24.
  • the radial consist of the screw from the axis of the sleeve 25 is selected so that the screw shaft engages radially in the circumferential groove 32 (see Fig. 4). This provides additional protection against inadvertent pushing together of the plug-in tube 23 and the socket tube 24 if the tension of the clamp 26 should decrease.
  • the tapered shoulders 34 on the plug and socket pipe 23, 24 have a small axial distance in the assembled state compared to the tapered extensions 33 of the transverse wall passages 14, 15, which absorbs different thermal expansions between the crankcase 13 and the channel-forming components.
  • the tapered shoulders 34 also act as an axial limitation for the back and forth movement of the clamped channel-forming components, which results during the operation of the piston internal combustion engine.
  • Two radially projecting cams 35 are formed on the outer circumference of the socket pipe 24. In the installed state, the cams 35 prevent rotation by contacting the contour 36 of the crankcase 13 of plug pipe 23 and sleeve pipe 24 about their common longitudinal axis. As a result, the accessibility of the tensioning device 27 of the clamp 26 and the openings 29, 30 is retained in the installed position, which facilitates disassembly that is required later.

Abstract

Le carter (13) d'un moteur à piston à combustion interne comporte, pour la distribution du lubrifiant, un canal qui se prolonge à travers plusieurs parois transversales (11, 12). Les sections du canal entre deux parois transversales (11, 12) se composent d'un tube emboîtable (23) et d'un tube à manchon (24) pouvant être déplacés l'un par rapport à l'autre et rendus solidaires dans le sens axial. Les extrémités libres du tube emboîtable (23) et du tube à manchon (24) sont disposées de manière à former une liaison étanche dans les passages pratiqués dans les parois latérales (14, 15) du canal. Cette disposition permet un usinage simplifié du carter (13) dans la région du canal.
