Definitions
- the present invention relates to a connecting device for hydraulically connecting an oil intake pipe provided on the side of an oil pan to an intake duct arranged on the side of an engine or transmission block and connected to an oil pump, in particular for use in a motor vehicle internal combustion engine.
- an oil pan is flanged, as a rule, below the actual engine and / or transmission block, which serves to hold lubricating oil in what is known as wet sump lubrication.
- An oil pump is arranged within the engine block, which sucks the oil out of the oil sump via an intake duct and a suction tube protruding downwards into the oil pan and feeds it into the engine oil circuit, from where it then runs back into the oil pan.
- the present invention has for its object to provide a connecting device of the type described above, which allows simplified assembly with a structurally simple and inexpensive design, wherein independence from manufacturing tolerances in the area of the oil pan intake pipe arrangement is to be achieved.
- a novel connector element which has an oil passage channel which is connected or connectable on one side to the intake pipe and on the other side opens with a channel opening in the region of an end sealing surface, the connector element being arranged or arranged in such a manner on the oil pan side, that by the joining process for the assembly of the oil pan to the engine or transmission block, the connector element with the sealing surface can be pressed sealingly against a bearing surface, which has a corresponding channel opening of the intake channel on the engine / transmission side.
- the oil connection device is joined indirectly solely through the joining process of the oil pan.
- the connector element is a connector element that seals exclusively axially on the end face by mere contact with the system, so that the desired tolerance independence is achieved in contrast to plug connections which are otherwise customary.
- the connecting device according to the invention can always be joined without any problems and free of transverse forces regardless of tolerance deviations, since a relative positional deviation between the connector parts, ie. H. a certain axis offset of the corresponding channel openings can be tolerated to a certain extent, since this could at most lead to a very slight and therefore harmless reduction of the flow cross-section in the sealing surface connection area.
- FIG. 1 is a perspective view of a connecting device according to the invention in a state before joining
- Fig. 2 is a view as in Fig. 1, but in the assembled state of
- Fig. 3 is a plan view of the connector element according to the invention.
- FIG. 4 shows an enlarged axial section in the plane IV-IV according to FIG. 3 in the not yet joined state according to FIG. 1,
- FIG. 5 shows a section as in FIG. 4 in the joined state according to FIGS. 2 and
- FIGS. 4 and 5 views analogous to FIGS. 4 and 5 in an embodiment variant of the connecting device according to the invention.
- the same parts are always provided with the same reference numerals and therefore generally only need to be described once.
- a connecting device 1 according to the invention is used for the hydraulic connection of certain components (not shown in the drawing), namely an oil intake pipe provided on the side of an oil pan with an oil pump provided on the engine or transmission side, in particular a motor vehicle engine.
- the connecting device 1 has a connector element 2 with a through-channel 4, which can be connected or connected on one side to the intake pipe (not shown) and opens on the other side with a channel opening 4a in the region of an end sealing surface 6.
- the connector element 2 is to be arranged or arranged in a fixed manner in the region of an oil pan, not shown, in such a way that the connector element 2 with the sealing surface 6 seals against a motor / transmission-side contact surface 8 indirectly by means of a joining process for connecting the oil pan to a motor or transmission block, also not shown can be pressed, a pump-side suction channel 9 with a corresponding channel opening 9a opening in the contact surface 8.
- the contact surface 8 and the intake duct 9 with its duct opening 9a are part of a separate, flange-like connecting element 10 (e.g. so-called oil pump flange) which is fastened on the motor side.
- a separate, flange-like connecting element 10 e.g. so-called oil pump flange
- the components mentioned can also be formed directly by appropriate design of the engine block.
- the connector element 2 consists of a dimensionally stable connector body 12 and an elastic sealing element 14.
- This sealing element 14 is advantageously designed to be elastically deformable or compressible in the joining direction, so that tolerance compensation is also achieved in this direction by the sealing element 14 can be deformed (compressed) to a greater or lesser extent.
- the sealing element 14 preferably consists of a tube-like central part 16, which surrounds the through-channel 4, with two sealing sections 18 and 20 which are opposite at both ends, in particular enlarged like a flange, and parallel to one another, the first sealing section 18 having a sealing surface 18a bears against a contact surface 22 of the connector body 12 and the second, opposite sealing section 20 forms the sealing surface 6 for sealing contact with the motor-side contact surface 8.
- the tube-like and thus elastically compressible middle part 16 has a circular cross-section, while the sealing sections 18, 20 enlarge outwards over the middle part 16 in such a way that they have, for example, an approximately diamond-shaped configuration with rounded corner areas.
- FIG. 3 this results in an essentially H-shaped contour of the sealing element 14, seen in the longitudinal section, the sealing sections 18, 20 forming the parallel H longitudinal webs and the central part forming the H transverse web.
- sealing element 14 It is therefore preferably a symmetrical configuration of the sealing element 14, which contributes to simple assembly, since it is irrelevant in which orientation the sealing element 14 is mounted.
- a spring element 26, in particular as a helical spring element, is arranged within the middle part 16 between two opposite, radially inwardly projecting web sections 24 of the two sealing sections 18, 20 of the sealing element 14 in such a way that, on the one hand, the sealing element 14 in the longitudinal direction of the through-channel 4 is elastically compressible (compressible) and the sealing sections 18, 20 are acted upon by a contact spring force F (see FIG. 5), and on the other hand the tubular middle part 16 is supported radially against vacuum-induced deformations.
- the sealing element 14 can advantageously be made very flexible and light in the region of the central part 16 and deformable over a large distance;
- the spring element 26 prevents the hose-like central part 16 from being contracted radially inward by the negative pressure which arises when oil is sucked in, because it is supported by the spring element 26.
- the sealing element 14 is connected to the connector body 12 such that it also fixes against loosening by joining the connection is held (loss protection).
- the sealing element 14 has a circumferential, lip-like edge web 28 in the outer edge region of each sealing section 18, 20. These edge webs 28 projecting in opposite directions overlap at least in a non-positive manner on the one hand a flange-like section 29 of the connector body 12 forming the contact surface 22 and on the other hand the pump-side connecting element 10 forming the contact surface 8 there.
- this also results in a fixation of the sealing sections 18, 20 against a vacuum-induced radial retraction in the direction of the arrows x shown in FIG. 5.
- positioning means are provided for automatically aligning the connector element 2 relative to the pump-side contact surface 8 or to the connection element 10 during the joining process.
- the positioning means are formed by at least two parallel position pins 32 which engage in position openings 30 during the joining process.
- the position pins 32 are preferably components of the connector element 2, in particular of the connector body 12, while the position openings 30 are provided in the area of the pump-side contact surface 8 or the connection element 10.
- the positioning means 30, 32 have a defined side play for tolerance compensation.
- the position pins 32 are expediently tapered at their free ends for insertion aid and / or the corresponding position openings 30 have corresponding funnel-like insertion bevels (not shown).
- the positioning means facilitate the correct alignment for joining the connecting device 1 according to the invention during the joining process of the oil pan.
- the sealing element 14 sits as an initially separate individual part with holes 34 in the area of the sealing sections 18, 20 on the position pins 32, which are in particular integrally connected to the connector body 12.
- the sealing element 14 in the region of the holes 34 facing the flange-like section 29 is held on the position pins 32 in a non-positive and / or positive manner by means of holding means 40.
- the holding means 40 can be designed in the manner of a latching connection or like a push button his.
- the edge webs 28 according to FIGS. 1 to 5 can also be omitted.
- the sealing element 14 can also be injection molded directly onto the connector body 12 and thereby also fixed in a materially integral manner.
- the connector body 12 is releasably connectable to the intake pipe and, in particular, has a conventional pipe connection piece 36 as a so-called mandrel profile.
- the connecting piece 36 together with the connector body 12 and the sealing element 14 can form a rectilinear through channel 4.
- any angular configuration is also possible, for example a right-angled outlet of the connecting piece 36.
- the connector body 12 can alternatively also be non-detachably, in particular integrally connected to the intake pipe.
- the connector body 12 is preferably detachably attachable to the oil pan and, for this purpose, has a lateral, flange-like retaining projection 38 in the embodiment shown.
- the connector body 12 and / or the suction pipe are / are designed as integral components of the oil pan, which is formed in particular from plastic or another suitable material.
- the connector body can be made of plastic or metal.
- the sealing element 14 consists of an elastomer, in particular a sprayable thermoplastic elastomer (TPE).
- TPE sprayable thermoplastic elastomer
- the spring element 26 can consist of metal, but also of plastic.
- the invention advantageously provides an interface between an oil intake pipe and the pump side that considerably simplifies assembly, this interface advantageously being independent of manufacturing tolerances is force-free in the transverse direction.
- the suction pipe can be fixed in the oil pan overall so that it is not susceptible to vibrations.
- the invention is not limited to the exemplary embodiments shown and described, but also encompasses all embodiments having the same effect in the sense of the invention. Furthermore, the invention has not yet been limited to the combination of features defined in claim 1, but can also be defined by any other combination of specific features of all the individual features disclosed in total.
