Definitions

  • the invention relates to a device for guiding lubricating oil according to the preamble of patent claim 1.
  • DE-42 04 522 C1 discloses a device in an internal combustion engine with a shell covering the crank mechanism toward the oil pan for draining off lubricating oil.
  • the shell which partly runs along the contour of the connecting rod violin, has an oil drain opening which acts as an oil plane.
  • This opens into a damping chamber for the gas impulses caused by the piston movement, this damping chamber having a further drain opening arranged below and to the side of the oil drain opening, through which the lubricating oil thrown off by the crank mechanism flows into the oil pan.
  • a balance shaft can rotate, which is at least partially enclosed by two struts protruding from the shell.
  • the disadvantage here is that the oil is foamed by contact with the rotating balancer shaft and gets into the oil sump in this state.
  • the invention has for its object to provide a generic device arranged between the crank mechanism and the oil pan for guiding lubricating oil in an internal combustion engine in such a way that the lubricating oil emitted by the crank mechanism reaches a non-foamed oil container.
  • the protruding struts of the shell form a profile that accommodates the intermediate shaft and is closed with respect to the crank mechanism, the intermediate shaft is sealed off against the entry of lubricating oil of the crank mechanism.
  • This lubricating oil gets under Bypassing the rotating intermediate shaft in the oil sump and is not foamed by the rotation.
  • a bottom of the shell in the area of the connecting rod violin contour is provided with these following curved segments, which run closely adjacent to this contour by means of the curvature and thus only leave a small gap in which oil can be mixed with air.
  • An arrangement of two drain openings in series with respect to the direction of rotation of the crankshaft and behind the profile ensures that the lubricating oil is drained away safely.
  • the amount of oil removed from the crank mechanism and thus not rotating with it can be increased if roof-shaped exposures are arranged behind the drain openings in the direction of the crankshaft, with wiping lips and extending directly to the connecting rod violin contour. These can limit drainage channels that contain the drainage openings and guide the absorbed lubricating oil into the oil sump.
  • a scraper extending right up to the counterweight contour can be arranged adjacent to at least one of the exposures.
  • the ends of the struts which are spaced from the bottom of the shell, can be provided, for example with elastic seals, against wall sections of the internal combustion engine in such a way that, together with the profile, they form a closed volume which extends along and receives the intermediate shaft.
  • These wall sections can be side walls of a crankcase which extend downward beyond the crankshaft or walls of an oil container which is flanged to the crankcase and is designed as an oil pan.
  • the one wall section can have an outlet opening for lubricating oil. The oil collected in the shaft formed between the one strut and the drainage channels and this wall section can thus be removed.
  • dry sump lubrication in this outlet opening are the suction point of the oil pump, which pumps the oil into an oil tank designed as a tank.
  • An outer, surrounding flange of the base can lie in a horizontal plane arranged between the crankshaft and the intermediate shaft, the flange also being supported on the wall sections with elastic seals.
  • These seals can be inserted, for example, as a sealing ring with a circular cross section in corresponding grooves in the flange or the struts.
  • they can be provided with a sealing lip which, when in contact with the corresponding wall section, is curved.
  • a suitably chosen direction of the curvature of the sealing lips ensures that, on the one hand, no oil can emerge from the shaft at locations not provided for it, on the other hand, a tunnel arranged on the opposite side of the intermediate shaft is secured against oil access from the crank mechanism and any oil in it is contained in one Channel of the volume receiving the intermediate shaft can flow off.
  • a two-row internal combustion engine not shown, with a V-angle of 180 ° has a crank mechanism with an axis AA in the shown direction of the arrow rotating crankshaft 1.
  • An intermediate shaft 2 rotates about its axis ZZ in the middle below the crankshaft 1.
  • a crankcase is divided vertically in half in a plane EE having axes AA and ZZ.
  • the halves have wall sections 3 and 4 running in a V-shape with respect to one another below the crank mechanism, with a single outlet opening 5 being arranged in section 4.
  • the crank mechanism has conventional counterweights located adjacent to connecting rod journals, which result in a counterweight contour K when rotating.
  • the connecting rods Z1, Z2, Z3 assigned to a row of cylinders generate a first connecting rod violin contour 6 with their connecting rods on the crank mechanism, the cylinders Z4, Z5 and Z6 assigned to the other cylinder row generate a second connecting rod violin contour 7.
  • a horizontal plane HH extends between the axes AA and ZZ perpendicular to the plane EE.
  • a shell 8 with a bottom 9 and an outer flange 10 extends essentially along this plane HH over the entire length of the crankshaft 1.
  • Two struts 11, 12 protrude from the shell 8 symmetrically to the plane EE, which together with a piece of the bottom 9 form a profile 13 which is closed with respect to the crank mechanism and which surrounds the intermediate shaft 2 in a U-shape.
  • the base 9 Below the connecting rod journals of the crankshaft 1, the base 9 has segments 14 and 15 which lie in front of the plane EE with respect to the direction of rotation of the crankshaft 1 and which follow the connecting rod violin contours 6 and 7 closely adjacent in a curved manner. Lying in a row behind the plane EE in the direction of rotation, the segments 14, 15 are adjoined by two roof-shaped displays 20 and 21, each provided with side walls 16, 17 and 18, 19. These each have wiping lips 22 and 23, which extend in the direction of the crank mechanism and point against the direction of rotation of the crankshaft 1, and which extend in the immediate vicinity of the connecting rod violet contours 6 and 7.
  • a drain channel 25 having a first drain opening 24 is formed, between the exhibition 21 and the exhibition 20, a drain channel 27 having a second drain opening 26.
  • a strut 12 and the Wall section 4 defines a shaft 28 which extends in parallel over the entire length of the crankshaft 1.
  • a closed tunnel 29 is formed on the opposite side of the plane EE between the floor 9 or its segments 14, 15, the other strut 11 and the wall section 3.
  • the elastic means are formed from attached seals 40, 41, which are each provided with a sealing lip 42, 43.
  • these sealing lips 42, 43 are curved against the wall sections 3, 4 in such a way that on the one hand the shaft 28 is secured against oil leakage and on the other hand the tunnel 29 on the flange 10 is sealed against oil ingress and an outflow on the strut 12 of any oil in the tunnel 29 into a channel 44 of the volume 39 is possible. From Fig. 5 it is clear that the sealing lips 42, 43 of the struts 11, 12 in the direction of rotation of the crankshaft 1 and that of the flange 10 are pre-curved to the opposite.
  • Each counterweight on the crankshaft 1 is assigned a scraper 45 which is arranged on the side walls 18 and 19 of the further exhibition 21 and extends to the immediate vicinity of the counterweight contour K.
  • the lubricating oil emitted by the crank mechanism is absorbed by the wiper lips 22 and 23 in the area of the connecting rods and guided into the shaft 28 via the outlet channels 25 and 27.
  • the oil is gripped by the wipers 45 and fed to the shaft 28 via the discharge channel 27.
  • the lubricating oil discharged from the bearings of the crankshaft 1 lying between the segments 14, 15 drips onto essentially flat surfaces 46 of the base 9 and flows to the shaft 28 via the outlet channel 25.
  • the oil flows to the outlet opening 5, which is located approximately in the middle with respect to the longitudinal extent of the shell 8. All the lubricating oil originating from the crank mechanism is thus discharged bypassing the intermediate shaft 2.
  • the distance to be covered by the oil on the floor 9, through the drain openings 24, 26 and in the shaft 28 to the outlet opening 5 enables the degassing of the lubricating oil to a large extent.
