Definitions

  • the present invention relates to an oil pump device for an internal combustion engine having an oil pan, the oil pump device having a sprocket and drive chain drivable oil pump and a provided with a sealing device shield which is disposed between a housing of the oil pump and the sprocket such that the sealing means at a Inner wall of the oil pan can be brought to bear and thereby forms a sprocket and arranged on the sprocket drive chain largely surrounding space.
  • the invention further relates to an internal combustion engine having an oil pan and an oil pump device according to the preamble of claim 7.
  • Internal combustion engines usually have a lubricant circuit in which a lubricant pump or oil pump is arranged, which conveys the lubricant in the form of oil from an oil reservoir to the corresponding lubricant points in the internal combustion engine.
  • a lubricant pump or oil pump is arranged, which conveys the lubricant in the form of oil from an oil reservoir to the corresponding lubricant points in the internal combustion engine.
  • internal combustion engines can have an oil pan, which also serves as a reservoir for the oil and provides the oil reservoir from which the oil pump removes the oil.
  • the oil pump may be, for example, a tandem pump which has two delivery units and can be flanged onto a cylinder crankcase of the internal combustion engine.
  • a drive chain which runs on a sprocket of the oil pump and is driven by the crankshaft of the internal combustion engine.
  • the oil pump is thus within the of the Sump defined space and therefore immersed in the oil reservoir.
  • the drive chain and sprocket immerse into the oil reservoir, causing the moving chain and sprocket in the oil reservoir to splutter.
  • the moving drive chain takes oil, this also often leads to an undesirable lowering of the oil level and also to a foaming of the oil, since the drive chain and the sprocket when immersed in the oil reservoir carry air and enter into the oil.
  • a shield which encloses the sprocket and the drive chain.
  • the shield is placed from the outside on a housing of the oil pump and by means of ⁇ labstreifkanten on the shield is trying to prevent the entrained by the drive chain oil in the cylinder crankcase of the internal combustion engine.
  • the drive chain and the sprocket still dive into the oil reservoir and in this way it comes to foaming of the engine oil. It is only an attempt to avoid an increase of the foamed engine oil in the crankcase of the internal combustion engine.
  • a shield of a sprocket of an oil pump of an internal combustion engine which surrounds the sprocket from the outside and is fixed to the crankcase of the internal combustion engine, thus creating a space in which the drive chain and the sprocket run and thus seals the shield against the oil pump housing.
  • This known shield is cup-shaped configured with side walls surrounding the sprocket and the drive chain, so that the known shield in a longitudinal sectional view has a large longitudinal extent and thus takes up much space.
  • This known oil pump combination has two pump chambers formed in a pump housing, in each of which a meshing gear pair is provided.
  • This known oil pump combination can be flanged to the underside of a cylinder crankcase of an internal combustion engine and has a sprocket, which is driven by a drive chain driven by the crankshaft of the internal combustion engine.
  • This known oil pump is arranged in an oil pan of the internal combustion engine, so that immerse the sprocket and the drive chain during the running of the internal combustion engine in the oil reservoir and thus provide the disadvantages mentioned above.
  • the shields already described above are intended to eliminate the problems associated with splashing the drive chain and sprocket in the oil reservoir.
  • the said shields are placed from the outside on the cylinder crankcase or the cylinder crankcase and the oil pump and must therefore be fixed after the assembly of the drive chain and the oil pump in an additional assembly process.
  • These known shields are therefore to be seen as additional components for the logistics and assembly in the manufacture of the internal combustion engine, which lead to a cycle time increase in the production of the internal combustion engine.
  • the shields are fixed by means of screw connections on the cylinder crankcase, so that the necessary screws and mounting holes lead to additional costs.
  • the known shields require space due to their cup-shaped configuration and therefore increase the overall length of the engine, which can only be absorbed by the fact that the engine compartment in a vehicle to be provided with the engine so equipped, is sized accordingly large.
  • Another oil pump device is based on the EP 0 744 533 A1 known. It is a fixed to a crankshaft bearing frame gear pump, which is driven by a drive chain and a sprocket from the crankshaft of the internal combustion engine.
  • This known oil pump device In this case has a shield which is fastened by means of a screw connection to a housing of the oil pump, wherein the shield is between the oil pump housing and the sprocket and cup-shaped and has a seal, which is bolted to the crankcase of the internal combustion engine oil pan on an inner wall of the Sump rested in such a way that both the drive chain and the sprocket of the oil pump and arranged on the crankshaft sprocket are arranged within a space enclosed by the crankcase and the oil pan.
  • the inner wall of the oil pan runs straight down from its connection surface on the underside of the crankshaft bearing frame. Since the shield of this known oil pump device is pot-shaped with a from an end face, which is aligned with the inner wall of the oil pan out to a housing of the oil pump back aligned rear wall extending side wall, the shield needs a lot of space in the engine longitudinal direction, which leads to it in that the internal combustion engine equipped therewith needs a lot of tree space in the engine longitudinal direction and, due to the associated large length of the oil pan in the engine compartment of the vehicle, less space is available for accommodating, for example, ancillary components.
  • the provided on the shield of the known oil pump device seal extends at an acute angle to its connection surface on the shield, so that in the arrangement of the oil pan to the crankcase of the internal combustion engine there is a risk that the seal is folded and thus the space in which the Sprocket and the drive chain of the oil pump run, is constantly completely filled with oil and thus the above-mentioned disadvantages are again present.
  • the present invention for eliminating the described disadvantages of the object to provide an oil pump device, which makes it possible to save in the engine longitudinal direction length in the oil pan and also to achieve a safe investment of the sealing device on the inner wall of the oil pan, without this a specific assembly sequence during installation of the oil pan on the crankcase of the internal combustion engine is required.
  • an oil pump apparatus for an internal combustion engine having an oil pan having a sprocket and drive chain drivable oil pump and a seal provided with a shield disposed between a housing of the oil pump and the sprocket such that the sealing means can be brought to rest on an inner wall of the oil pan and thereby forms a sprocket and arranged on the sprocket drive chain largely surrounding space, the shield is largely flat and the sealing device extends largely perpendicularly away from the shield.
  • the voltage applied to the inner wall of the oil pan sealing device forms together with the inner wall at least in the region of the sprocket and arranged on the sprocket drive chain a space that is open only in the direction of a crankshaft of an internal combustion engine arranged sprocket - so here the drive chain can run freely -, the space around the arranged on the oil pump sprocket and the drive chain arranged thereon but otherwise surrounded by the sealing device and the oil pan.
  • the shield of the oil pump device is largely flat, so has no side walls to form a cup-shaped shield, as is the case with the known shields, but is flat and flat and has a sealing device which extends from the shield largely at right angles and thus does not have the risk of folding over the sealing device more when the oil pan is attached to its inner wall, at which the sealing device comes to rest on the crankcase of the internal combustion engine, but regardless of the mounting sequence in which the oil pan is placed on the crankcase, a defined system of sealing means on the inner wall of the oil pan is achieved with such a bias that an uncontrolled influx of engine oil is avoided in the space thus formed.
  • the oil pan when the oil pan is moved from below toward the crankcase supporting frame, the edge formed between the inner wall of the oil pan and the connecting surface of the oil pan for arrangement with the crankshaft supporting frame comes into contact with the sealing device of the known shield and folds it above.
  • the oil pan In order to avoid this folding of the seal, the oil pan must first be considered in the engine longitudinal direction spaced from the provided on the crankshaft bearing space connecting surface of the oil pan and then axially displaced until the inner wall of the oil pan comes into contact with the seal on the shield, so that a folding of the seal is avoided.
  • the oil pan must therefore be initially moved vertically to the crankcase of the internal combustion engine during their assembly and then moved horizontally until the seal of the shield rests against the inner wall of the oil pan.
  • the sealing device according to the invention is configured on the shield to extend at right angles therefrom, such that vertical application of the oil pan to a cylinder crankcase of an internal combustion engine simultaneously results in seating of the sealing device on the inner wall of the oil pan and thus the sprocket and the drive chain arranged thereon are surrounded by a space that is separated from the Seal means and the inner wall of the oil pan is formed and a folding of the sealing device is avoided.
  • the largely planar shield has in the region of its peripheral edge a groove for receiving the sealing device.
  • the shield may have, in the region of the peripheral edge, a stiffening extending out of the plane of the shield in which the groove extends, in which the sealing device can in turn be fixed.
  • the shield of the oil pump device according to the invention has no side wall which extends so far from the shielding plane from the plane of the shield that the sprocket is cup-shaped enclosed by the side wall of the shield, but only in the groove
  • the sealing device accommodated at the peripheral edge largely extends at right angles away from the shield, but does not form a space enclosing the sprocket cup-shaped space, but only creates the space surrounding the sprocket and the drive chain largely by abutment with the inner wall of the oil pan.
  • the known shield is fixed by means of a screw connection to the housing of the oil pump.
  • This attachment was therefore chosen so that by tightening the screw connection between the shield and the housing of the oil pump such a large surface pressure is achieved that oil from the oil reservoir is not through an otherwise resulting gap surface between the shield and the housing of the oil pump in the room in which the sprocket wheel fixed to the oil pump shaft rotates.
  • the shield on the oil pump device according to the invention has a circumferential groove into which a projection formed on the housing of the oil pump engages in such a way that the groove and projection form a labyrinth seal.
  • This labyrinth seal is not hermetically sealed, so that in the above-described space between the seal means and the inner wall of the oil pan through the labyrinth seal Engine oil can migrate when the engine is, for example, at a standstill and not running.
  • the circulating drive chain ensures after a short time that the engine oil in the room is pumped out of the room and then no splashing losses and no foaming of the engine oil in the space formed by the sealing device and the inner wall of the oil pan more are possible, since this has been largely emptied, due to the labyrinth seal between the groove and the projection but a running of engine oil in the so empty pumped space during the running of the engine is so slow vonstatten that the sprocket when running the engine is no longer in a immersed in the space standing oil volume.
  • the shield has at least one opening which fluidly the space between the inner wall of the oil pan and sealing means with an oil reservoir in the oil pan connects so that through this opening engine oil from the oil reservoir in the oil pan can flow into the room, but the opening is so dimensioned that this Nachströmen does not lead to a refilling of the room during operation of the engine with corresponding splash losses and a corresponding foaming of the Engine oil in the room, but the engine oil flows from the oil reservoir in the room mainly during the stoppage of the internal combustion engine.
  • the shield provided according to the invention on the housing of the oil pump must not be set with high surface pressure, but may be formed of a plastic material and a U -shaped configuration with outwardly extending lugs on which latching elements are arranged to engage in openings of the housing of the oil pump for releasably securing the shield.
  • the formation of the shield made of a plastic material saves processing steps, since the shield can be finished during its manufacture with the locking elements and the groove for receiving the sealing device.
  • the formed between the sealing device and the inner wall of the oil pan space may be formed open due to the formation of the sprocket and the chain track of the drive chain U-shaped and towards the arranged on the crankshaft sprocket, so that the shield has a U-shaped configuration and thus by the provided in the groove of the shielding sealing means and their contact with the inner wall of the oil pan a unilaterally open U-shaped space for receiving the sprocket and the drive chain is provided.
  • outwardly extending lugs are provided at which locking elements are formed for engagement in openings of the housing of the oil pump in example to be called injection molding of the shield, so that the shield is latched via these locking elements with openings of the housing of the oil pump , Without that between the rear wall of the shield and the housing of the oil pump, a high surface pressure, as well as this area does not have to be hermetically sealed, but can flow through the thus existing gap surface between the rear wall and the shield at standstill of the engine oil in the room , which is then pumped out quickly when starting the internal combustion engine through the drive chain.
  • the arranged on the shield sealing means is formed of an elastomeric material and has in a section a substantially wedge-shaped configuration, so that the inner wall of the oil pan with the thus formed largely wedge-shaped sealing lip of the sealing device comes into contact and an afterflow of engine oil from the oil reservoir in the oil pan is avoided in the space between the sealing device and the inner wall of the oil pan during operation of the internal combustion engine by the sealing device.
  • the invention now also provides an internal combustion engine with an oil pan and an oil pump device, as described above, in which the sprocket and the drive chain are at least partially received in a recess formed on the inner wall of the oil pan and the recess largely surrounded by the sealing device is.
  • the invention is therefore also distinguished by the fact that the oil pan on the inner wall has a recess, so that in this recess the sprocket and the drive chain of the oil pump device are at least partially included, which in addition to the formation of the shield without side walls turn the required installation space length of the oil pan and thus reduces the internal combustion engine in the engine compartment of a motor vehicle.
  • the sealing device on the shield now surrounds this recess at least in the range of the sprocket and arranged on the sprocket drive chain so that the largely surrounded by the sealing device recess is pumped so far by the drive chain during the running of the internal combustion engine that the sprocket and the drive chain during the course of the internal combustion engine not Immerse more in a stagnant oil level and thus Splash losses are avoided and it no longer comes to foaming the engine oil.
  • the sealing means on one of the inner wall the oil sump formed abutment surface and in a section, the contact surface with a longitudinal sectional plane of a sealing lip of the sealing device forms an angle of at least 90 °.
  • the contact surface can now have an angle of, for example, 135 ° to an inner peripheral surface of the recess in the region of the abovementioned recess of the oil sump, so that the sealing device resting against the abutment surface comes into abutment against an inclined abutment surface and thus due to the emergence of the sealing device on a obliquely extending contact surface of the oil pan when mounted on the crankcase folding over the sealing device during assembly of the oil pan to the crankcase of the internal combustion engine is avoided.
  • the drive chain running over the sprocket on the shaft of the oil pump and the sprocket of the crankshaft spans a chain track plane.
  • the oil pan can be fixed in the region of the recess by means of screw connections to the cylinder crankcase of the internal combustion engine and the oil pan adjacent to the recess has bores which are arranged outside the chain track plane of the drive chain.
  • Fig. 1 of the drawing shows an embodiment of an oil pump device according to the present invention in a perspective view.
  • the oil pump device 1 has an oil pump 2 with a housing 3 and has in the illustrated embodiment, a stiffening shell 4, which is fixed to the housing 3 by means of screw and the oil pump device 1 by means provided on the housing 3 and the stiffening shell 4 mounting holes 5 on a Underside of a crankcase of an internal combustion engine, not shown, can be attached.
  • the stiffening shell 4 has recesses 6, can dive into the connecting rods or crank webs of the crankshaft of the internal combustion engine.
  • the stiffening shell has 4 holes and passages for the passage of oil pumped by the oil pump 2 in the lubrication circuit of the internal combustion engine.
  • a shield 8 is arranged with a groove 11 which can be seen in greater detail with reference to FIG. 3, in which a sealing device 9 with a sealing lip 10 is arranged.
  • the shield 8 has an overall U-shaped configuration and is releasably fixed by means of latching elements 12 on the front or end face 7 of the housing 3 of the oil pump 2.
  • the shield 8 is disposed between the housing 3 of the oil pump 2 and a releasably fixed to a shaft of the oil pump 2 sprocket 13.
  • a drive chain 14 is provided for driving the sprocket 13 and thus the oil pump 2.
  • the oil pump device 1 according to FIG. 1 can be preassembled as a prefabricated oil pump module and thus integrated into the manufacturing process of the internal combustion engine, not shown.
  • the oil pump device 1 can be attached via the mounting holes 5 on the underside of the crankcase of the internal combustion engine and the drive chain 14 are placed on a fixed to the crankshaft of the internal combustion engine sprocket.
  • Fig. 2 of the drawing shows in a longitudinal sectional view of the oil pump device of FIG. 1 with a pushed from below onto the crankcase of the engine and attached thereto oil pan 15.
  • the shield 8 is largely flat and has no extending from the plane of the shield 8 Side wall, as is the case with the known shield, since this would be accompanied by an increase in the required installation space.
  • the fixed by means of the locking elements 12 to the housing 3 of the oil pump 2 shield has a groove 16 into which engages a formed on the housing 3 of the oil pump 2 projection 17 and forms a labyrinth seal.
  • the sprocket 13 and the drive chain 14 is received, so that the space 19 is largely emptied of the moving drive chain 14 after the start of the internal combustion engine , so that the drive chain 14 and the sprocket 13 are no longer immersed in an oil reservoir standing in the space 19 and thus the problem of splashing losses and foaming of the engine oil is avoided.
  • a bore 25 is formed in the shield in the lower region, which has a diameter of 1.2 mm, for example, so that at standstill of the engine engine oil can flow slowly into the space 19 and thus measurements not be falsified by the fact that the space 19 is filled once with oil and not at the next measurement.
  • FIG. 2 and FIG. 3 make it clear that the sealing device 9 with its sealing lip 10 on the contact surface 18 of the oil pan 15 rests in such a way that in the illustrated embodiment, the contact surface 18 in a sectional view with a longitudinal sectional plane of the sealing lip 10 forms an angle of about 135 °, wherein an angle of 90 ° would be reached if the contact surface would not be formed with a sloping surface but would represent a 180 ° extension of the inner wall 20 of the oil sump. Due to the oblique design of the contact surface 18 but it is achieved that a folding of the sealing lip 10 of the sealing device 9 is avoided during assembly of the oil pan 15 to the crankcase of the internal combustion engine.
  • sealing device 9 and the connection surface 18 and the inner wall 20 of the oil pan 15 can be adjusted so that in the space 19 in an uncontrolled manner constantly oil flows from the oil reservoir in the oil pan, so that in the space 19 the same Oil level prevails, as in the oil reservoir of the oil pan.
  • the oil pan 15 has a recess 21 in which the sprocket 13 and the drive chain 14 are received, so that the oil pan 15 and thus the internal combustion engine overall have a shorter overall length than is the case in the known oil pump combination described above.
  • the sealing device 9 extends largely at right angles away from the shield and thus allows a secure contact with the contact surface 18 of the oil pan 15. Without the recess 21, the oil pan 15 would have to be made longer, since it would have to be guided around the drive chain 14 or the sprocket 13 and thus would have a longer design. This would increase the space required when installing the provided with the oil pump device internal combustion engine in the engine compartment of the motor vehicle.
  • the oil pan 15 has bores 22, by means of which it can be fastened by means of screw connections to the cylinder crankcase of the internal combustion engine, whereby boreholes provided adjacent to the recess 21 extend outside a chain track plane defined by the sprocket 13 and the drive chain 14 and thus no screw connections lie behind the chain track plane , which in turn can be saved installation space length.
  • the sealing surface 24 of the oil pan 15 is reduced to a required for sealing width of the sealing track, which in turn benefits the reduced length of the oil pan and thus the internal combustion engine for installation in the engine compartment of the vehicle.
