Definitions

  • the invention is based on a screw connection of crankshaft bearing caps of EP-A-0 255 707.
  • the invention and EP-A-0 255 707 have the same priority and registration date.
  • oil pans with differently arranged oil sumps may be required.
  • the invention has for its object to reduce or keep the scope of various suction-side devices.
  • the basic idea of the invention is to provide the multi-use screwing of crankshaft bearing caps described in EP-A-0 255 707 for a larger number of crankshaft bearing caps for the optional arrangement of a lubricating oil pump and a structurally separate drive device serving for the lubricating oil pump.
  • the lubricating oil pump can be placed in different oil sumps, each with a differently arranged oil sump, without special measures.
  • the distance between the drive device placed essentially at the end and the lubricating oil pump placed on one of the crankshaft bearing caps depending on the respective oil sump is bridged by a shaft which is adapted in length to the respective distance.
  • the invention advantageously enables, on the one hand, an optionally disposable lubricating oil pump and, on the other hand, the gear carrier of the drive unit, which is positioned identically in all identical internal combustion engines, a device of essentially the same type on the suction side.
  • this device can advantageously be further developed in that the gear carrier additionally has a pump-side inflow channel and an outflow channel aligned with a crankcase-side line.
  • the gear carrier additionally has a pump-side inflow channel and an outflow channel aligned with a crankcase-side line.
  • gear carrier for tensioning an endless traction means interacting with the drive wheel can be positionally adjustable on the opposite side via a rotatably arranged threaded bushing with the holder loosened.
  • a crankcase 10 for a multi-cylinder internal combustion engine has a plurality of bearing walls 11, indicated by dash-dotted lines, which, as can be seen from FIGS. 2 and 3, connect outer walls 12 of the crankcase 10 to one another. Furthermore, the axis of rotation is indicated at 13 for a crankshaft, not shown.
  • a lubricating oil pump 15 is driven from the crankshaft via an enveloping gear 14.
  • the lubricating oil pump 15 has a suction head 16 which is integrally connected to the housing.
  • the lubricating oil pump 15 is arranged correspondingly away from the plane of the enveloping gear 14.
  • a drive wheel 19 of the casing gear 14 and a lubricating oil connection to the crankcase 10 are in a separate carrier 20 arranged.
  • the lubricating oil pump 15 is in drive connection with the drive wheel 19 of the enveloping gear 14 on the carrier 20.
  • the lubricating oil pump 15 is connected via a pipeline 22 to the lubricating oil connection in the carrier 20 to the crankcase 10.
  • Each of the transverse walls 11 is formed with a split crankshaft bearing 23, with each course Belwellenlager 23 each includes a screwed to the transverse wall 11 bearing cap 24.
  • a bearing cap screw connection comprises screw bolts 25 and 26 designed as cap screws, each with a stop surface 29 that faces away from the machine on the machine-side clamping surface 27 on the head 28 or a retaining flange 31 of the carrier 20 passing through threaded bolt 32.
  • the other screw bolt 26 has a blind hole thread 33 in its head 28. This arrangement applies in particular to screw bolts 25 and 26 arranged inclined to one another.
  • the carrier 20, which carries the drive wheel 19 of the enveloping transmission 14 for driving the remotely located lubricating oil pump 15, has an inflow channel 34 on the pump side and an outflow channel 35 adjacent to the fastening point with the threaded bolt 32.
  • the outflow channel 35 is arranged with a line 36 on the crankcase side, essentially parallel to the common axis of the screw bolt 25 and the threaded bolt 32.
  • a connecting tube 37 is provided for the oil-carrying connection of the outflow channel 35 to the crankcase-side line 36, which is centered in the respective end region in the outflow channel 35 and in the line 36 by an elastic radial sealing ring 38.
  • the carrier 20 is equipped with a threaded bushing 40 which is rotatably arranged in a threaded through bore 39 and which rests on the stop surface 29 arranged on the head 28 of the screw bolt 26, the carrier 20 with a loosened nut 41 is adjustable on the threaded bolt 32.
  • the lubricating oil pump 15 has a threaded through bore 39 in a holding flange 42.
  • a connector 43 for a carrier-side discharge channel 44 it also has a further connector 45 for a crankcase-side discharge channel 35.
  • a coupling socket 46 of the lubricating oil pump 15 is designed for a direct connection to the drive wheel 19 of the enveloping gear 14. The above-described design of the lubricating oil pump 15 enables a uniform pump housing, one of the outflow channels 35 or 44 being closed, depending on the positioning of the lubricating oil pump 15.
