Definitions

the invention relates to an internal combustion engine of the type described in the preamble of the main claim.
oil pans with differently arranged oil sumps may be required.
the invention has for its object to reduce the scope of various suction devices or to keep it small.
the basic idea of the invention is to use the clamping elements known from an internal prior art in the screwing of bearing caps for a separate arrangement of a unit from the outset in the screwing of bearing caps which are adjacent to the differently arranged oil sumps in the different oil sumps.
the associated fastening point is thus arranged for the assembly-related assignment of the suction-side device for each of the different oil sumps.
the required different ones are Fastening points already exist.
the invention advantageously enables the use of a suction-side device or an aggregate of essentially the same type for the different arrangements corresponding to the differently arranged oil sumps.
the transmission carrier additionally has a pump-side inflow channel and an outflow channel aligned with a crankcase-side line, then only a correspondingly long drive shaft and a correspondingly long conduit are required between the gearbox carrier and the correspondingly positioned lubricating oil pump for the functional connection. The amount of parts of the suction-side device to be stored is thus reduced to a minimum.
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 an intake cage 16 which is integrally connected to the housing.
the lubricating oil pump 15 is correspondingly arranged 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, each crankshaft bearing 23 each comprising a bearing cover 24 screwed to the transverse wall 11.
a bearing cover Screw connection comprises screw bolts 25 and 26 designed as cap screws, each with a stop surface 29 facing away from the machine on the clamping surface on the head 28.
the screw bolt 25 also has on its head 28 a retaining flange 30 of the lubricating oil pump 15 or a retaining flange which projects beyond the stop surface 29 31 of the carrier 20 penetrating 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 pipe 37 is provided, which in the respective end region in the outflow channel 35 and in the line 36 each by a elastic radial sealing ring 38 is centered.
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.
