Figs. 1 to 4 show parts for explaining a crank mechanism of a machine with a Brennkraftma disposed below a crankcase to a support structure 3, formed as balance shaft 20 secondary shaft.

The reciprocating piston internal combustion engine has a crankcase (not shown) with a crankshaft 1 rotatably mounted therein. Lateral walls of the crankcase are guided beyond the center of the crankshaft 2 in the direction of an oil pan, not shown, into a flange plane E. Connected to this flange plane E in the direction of the oil pan is a component, which is connected to the walls of the crankcase and is denoted overall by 3 and is referred to below as support structure 3 . This is essentially plate-like and extends in the longitudinal direction L and transverse direction Q of the crankcase and separates through its connection to the opening area of the crankcase surrounding the flange, generally designated 4 crank mechanism from the oil pan substantially.

The the crank mechanism 4 facing surface of the support structure 3 is formed at least in the range of crank webs 6 of the crank mechanism 4 according to the created there by the rotation Pleuelgeigenstruktur.

On its surface 7 facing away from the crank mechanism 4 and facing the oil pan, the support structure 3 carries bearing blocks 10 and 11 which are formed in one piece and of the same material, each having an undivided bearing 8 and 9 .

The support structure 3 is essentially rectangular in shape, with fastening eyes 14 for carrying out screw connections being arranged on the longitudinal sides 12 and 13 . The long side 12 is essentially covered in the illustration in FIG. 1. With the screw connections, the support structure 3 is fixed in the flange plane E on the crankcase.

End faces 15 and 16 each extend in the longitudinal direction L between the longitudinal sides 12 and 13 at the ends. One end face 15 is designed as an end wall 17 and, among other things, integrally accommodates the bearing block 10 .

In the assembled condition of the support structure 3 according to Fig. 2, 3 and 4 in the bearings 8 and 9 are denoted overall by 20 sub-shaft is rotatably held. This is provided integrally and in one piece with a balancing mass 21 and is inserted from the end face 16 first through the bearing 9 and then through the bearing 8 . On a in the inserted state of the bearing 8 penetrating, stepped pin 22 of the auxiliary shaft 20 , a drive wheel 23 designed as a chain wheel and then another equal mass 24 is placed on. This arrangement, together with a collar 26 of the countershaft 20 resting against the inside of the end wall 17, ensures axial support, while the bearing 9 is designed as a floating bearing.

The floating mounting of the balancing mass 21 ensures that this balancing mass 21 is moved towards the support structure 3 in an optimal space. In a section 7 a, this has correspondingly shaped contour surfaces 27 to create a free passage.

Crossing stiffening ribs 30 are arranged between the two bearing blocks 10 and 11 , which intersect at intersection points 31 .

The auxiliary shaft 20 is driven by an output gear 40 of the crankshaft 1 . Together with the drive wheel 23, this driven wheel 40 defines a drive plane T for a chain 41 . As can best be seen from FIGS. 2 and 3, the chain 41 drives the auxiliary shaft 20 with its rear side to reverse the direction of rotation. For this purpose, two deflection wheels 42 are provided, one of these deflection wheels 42 being rotatably held in a bearing 43 in the end wall 17 . Another deflection wheel 42 acts as a drive wheel for an oil pump, not shown, of the reciprocating piston internal combustion engine. For optimal use of installation space, this is detachably arranged on the support structure 3 between the inside 25 of the end wall 17 , the surface 7 and next to the auxiliary shaft 20 . The surface 7 carries fastening points 44 for this purpose.

To supply the bearings 8 and 9 with lubricating oil and to avoid external lines, the support structure 3 has a channel system for lubricating oil. Starting from the flange plane E, an essentially transverse inflow channel 45 extends in the area of the bearing block 11 and extends to the bearing 9 there. In a shaft 46 protruding from the surface 7 , a supply channel 47 intersecting the inflow channel 45 extends parallel to the auxiliary shaft 20 and conveys the supplied lubricating oil to the bearing 8 . The shaft 46 receiving the supply channel 47 runs along a series of crossing points 31 .

As can best be seen from FIG. 1, the surface 7 also carries a web 32 , on which a capsule device according to the invention of the drive shaft 20 described below abuts. This web 32 extends starting from the end wall 17 , spaced apart and parallel to the long side 13 along the end side 16 and again offset inward, essentially parallel to the other long side 12 . In the area of these long sides 12 and 13 , window-like openings 33 for the passage of lubricating oil of the crank mechanism 4 into the oil pan are arranged between the web 32 .

Fig. 5 to 9, the above-mentioned capsule device of the invention in 49 show a preferred embodiment. This includes a trough-like housing 50 , which in a peripheral contour and in a peripheral tub only partially visible in FIG. 5, edge 64 of the contour of the web 32 of FIG. 4 is adapted such that it can be flanged onto the web 32 and the countershaft 20 against encapsulates an oil pan. In the preferred embodiment shown, the capsule device 49 further comprises fastening eyes 52 , clip connectors 54 , a snorkel flange with cover 56 , a snorkel 58 and an oil suction opening 60 .

FIG. 6 shows in detail the area of the oil suction opening 60 which, in addition to the snorkel flange with cover 56, also comprises a sieve 62 . The cover 56 with the snorkel 58 ( not visible in FIG. 6) is arranged on the oil pan side, ie in the installed position below the capsule device 49 . On an opposite side facing the crankcase or the support structure 3 in an interior of the capsule device 49 , a connecting piece 66 formed integrally with the housing 50 is provided. When the capsule device 49 is mounted on the support structure 3, this connecting piece 66 interacts with an intake port 67 of the oil pump in such a way that the oil pump is connected to the snorkel 58 and pumps and delivers oil from an oil sump. The connection port 66 and the oil pump or its intake 67 are arranged such that this connection is automatically established by attaching the capsule device 49 . Additional installation work for connecting the oil pump is therefore not necessary. At the same time, the intake port 67 acts as a centering for the housing 50 . During assembly, the strainer 62 is first inserted into the oil suction opening 60 and the cover 56 is placed on it. In this assembly stage, the latter abuts an elevation 68 which runs around the oil intake opening 60 and is accordingly spaced apart from the strainer 62 . In a subsequent processing step, the cover 56 is friction welded onto the elevation 68 , as a result of which the elevation 68 partially melts and the lid 56 moves downward in FIG. 6 until it rests on the screen 66 . Further friction welding now connects the cover 56 to the sieve 66 and the housing 50 on the circumference of the sieve 66 within the elevation 68 . This two-stage friction welding ensures a secure, firm and tight connection in the area of the oil intake opening 60 .

In Fig. 7, the snorkel 58 is shown in solid lines for a certain internal combustion engine, while a shortened snorkel 58 is shown in dashed lines for a certain internal combustion engine with a different stroke volume and / or a different installation position.

Fig. 10 shows a detailed representation of an attachment eye 52 on the housing 50. To attach the capsule device 49 , a screw 53 is carried out on the oil pan side in the direction of the arrow 70 through the attachment eye 52 and is screwed on the crankcase side either on the crankcase or on the attachment points 44 ( FIG. 1) of the support structure 3 . An integrally formed with the housing 50 ring web 59 in a recess 61 is plastically pressed by the screw head 53 a and makes a separate sealing ring unnecessary. The screw torque is supported on the crankcase or the lead frame, but not on the housing 50 . As a result, there is no independent loosening due to creeping of the housing material.

The clip connector 54 shown in detail in FIGS . 11 and 12 can be provided in addition to the fastening eyes 52 or instead of these. The clip connector 54 comprises a hook-shaped element 55 which is fastened to the housing 50 via an elastic arm 57 . When sliding on the bar 32, the hook-shaped member 55 engages the web 32 as shown in Fig. 12, and fixed so the housing 50 in a predetermined position below the crankcase. An inserted sealing cord 72 seals the Ge housing 50 on a circumferential support surface on the web 32 against the interior of the surrounding oil pan. The clip connections 54 have the advantage that they can be released again just as easily and quickly as they were previously produced by “clipping on” the housing 50 . Thus, the capsule device 49 can also be dismantled easily and quickly, for example for later maintenance or repair work.

Fig. 13 shows the lid 56 with filter 62 in an enlarged view in a view from the crankcase side. The screen 62 is preferably tilted at a predetermined angle to the oil pan or to the oil sump contained therein, so that the oil conveyed by the pump via the screen 62 has to overcome an enlarged screen area along the screen 62 . In this way, the extracted oil is freed of air bubbles that separate on the screen 62 .

The capsule device 49 advantageously prevents a "splashing" of the rotation of the auxiliary shaft 20 in the oil sump, which would lead to an undesirable foaming of the oil and unnecessary loss of work. The integrated in the capsule device 49 suction snorkel 58 for the oil pump reduces the total number of parts when assembling the internal combustion engine. The capsule device 49 , for example, only takes up oil which is conveyed to the auxiliary shaft 20 for its lubrication, and in such an embodiment the oil flowing out of the crank mechanism is passed completely past the auxiliary shaft 20 into the oil pan.
