Description

The invention relates to an oil pan for an internal combustion engine which is formed trough-shaped, comprising a bottom portion and these surrounding side surfaces which can be connected at its free end via a flange on an internal combustion engine, wherein the oil pan made of plastic or a composite material.

To reduce the noise emission of oil pans is from the published patent application DE 10 2006 004 432 A1 an apparatus and a method are known in which the cast aluminum sump oil pan is provided with an insulating layer and with an outer barrier layer, wherein the outer barrier layer, for example, urethane and the insulating layer of foam rubber.

From the patent DE 103 02 191 B4 An oil sump comes out, which has a reduced sound radiation and a low weight. For this purpose, the wall of the oil pan is made of plastic, wherein the conversion is partially replaced by a multi-layer part having at least one metal sheet and at least one formed of plastic or a viscoelastic material layer, said multi-layer part at its edge with the plastic of the oil pan wall is overmoulded. The fact that the multi-layer sound-absorbing part is preferably arranged in the tub bottom, the tub bottom and thus the area of the oil pan is responsible for the strongest sound radiation usually steamed.

The invention has the object of providing an oil pan for internal combustion engines with the feature of the preamble of claim 1 such that the radiated from the oil pan airborne sound, the noise characteristics of the engine positively underscores and thus contributes to the acceptance of the noise of the engine at the customer. It is another object of the invention to reinforce positively perceived Psychoakkustische parameters and thus to achieve a targeted noise control. In particular, the load condition of the unit should be as meaningful as possible to the operator. This is to be achieved by an oil pan whose production costs are low and whose production is easy to carry out.

This object is solved by the features of claim 1. Advantageous developments of the invention will become apparent from the dependent claims 2-15.

As a core of the invention, it is considered that at least one side surface of the oil sump is provided with at least one influence region, which comprises a jacket surface and a vibration influencing surface, wherein the vibration influence surface is at least partially offset from the main extension plane of the side surface associated with the influence region. The oscillation influencing surface shoots against the lateral surface at least in regions and is at least partially spaced from the main extension plane of the side surface assigned to the influence region. In this case, the oscillating influence surface has a lower rigidity and / or elasticity than the lateral surface, so that a different sound radiation property results. Due to the targeted design of the influence range such that the oscillation influencing surface is surrounded by the stiffer lateral surface at least partially, preferably completely, the sound radiation of the influence region can be specifically influenced and thus the sound emitted by the oil sump can be influenced accordingly. It is advantageous if the lateral surface is at least a factor of 1, 2, preferably at least a factor of 2, more preferably at least a factor of 4 stiffer than the adjacent Schwingeinfluidbereich.

The lateral surface preferably completely encloses the oscillation-influencing region and forms the connecting member of the oscillation-influencing region to the corresponding side surface. This can be achieved in a simple manner a defined-acting vibration influence range.

The invention is based on the finding that the acoustic influence of an oil pan on the one hand can go to make them such that the sound is attenuated, but the performance of the invention is additionally or alternatively in that it was recognized that the of an oil pan radiated sound can be guided by the provision of influence areas targeted to a desired frequency range and / or a targeted reaction with other radiated from the oil pan of the adjacent components or frequencies, so that the total radiated from the oil pan sound is in a desired frequency range. Thus, the euphony and the acceptance of the noise of the oil pan itself or in the mounted state with respect to the psychoacoustic parameters can be positively influenced. For example, a positive feedback on the load condition of the engine is thus achieved.

In a preferred embodiment, the vibration influencing surface is arranged parallel to the main extension plane of the side surface assigned to the influence region. For example, the lateral surface rises at right angles to the main extension plane of the side surface of the oil sump and, as a conclusion, comprises a vibration-influencing surface oriented parallel to the main extension plane. By These "outstanding" areas of influence can be implemented in a technically simple and effective way, a targeted influencing the noise characteristics of the oil pan.

Also, the oscillating influence surface to the main extension plane may include an angle of 1 ° to 60 ° with this. In particular, this is at a distance of advantage. Also, at least one oscillation-influencing surface may be a surface curved around at least one axis. By free-form design of a vibratory influence surface requirements with respect to package / space resources can be met. For example, other vehicle components mounted close to the sump may require the freedom of design of the sump and, more particularly, the areas of influence, a non-planar shape of the oscillating surfaces of impact.

Another preferred feature of the invention is that the area of influence is formed integrally with the oil sump. Due to the fact that the oil sump is made of plastic, the sphere of influence of the oil sump can be realized on a production-wise simple and at the same time a high degree of design enabling manner. Alternatively, the oil pan can also be made of a composite material such as elastomers, sandwich materials, elastomer / composite sheet and / or laminated foams, thereby asymmetric radiation characteristics and targeted radiation directions can be achieved.

Further, it is advantageous if the vibration influencing surface is formed thinner wall than the lateral surface and / or at least in the transition region of the Schwingeinflussfläche to the lateral surface a material taper and / or an elastic, the Schwingeinflussfläche with the lateral surface connecting coupling element is arranged. By forming the vibration influencing surface with a thinner material thickness than the lateral surface, the preferred way of selectively influencing the influence regions can be realized. Alternatively or additionally, a material taper and / or an elastic coupling element connecting the swing-influencing surface of the lateral surface may be arranged in the transition region of the oscillating-influencing surface to the lateral surface. By the material tapering and / or the coupling of the two elements by an elastic element, the different rocking properties of the two elements are influenced, in particular realized the desired rocker property of the Schwingeinflussfläche relative to the lateral surface in a technically simple manner.

A further alternative or additional advantageous measure for realizing a stiffer lateral surface relative to the vibration-influencing surface can be achieved in that the lateral surface is provided at least in regions with reinforcing ribs and the Schwingeinflussfläche is provided with no or to a lesser extent with a stiffening. The stiffening to a lesser extent may include stiffening ribs and / or geometric changes. Preferably, the stiffening ribs for stiffening the lateral surface are at least on the inside - in the final assembly state of the engine-facing side of the oil pan - arranged. Alternatively or additionally, the stiffening ribs on the outside, d. H. be arranged in the final assembly state of the oil pan on the side facing away from the engine of the oil pan. If the stiffening ribs are mounted on the outside, they can additionally have the function of sacrificial ribs, so that, for example, by mechanical effects such as rockfall the stiffening ribs are upstream as protection and sacrificial barrier of the oil pan walls.

Further, it is advantageous if the stiffening ribs are made in one piece with the oil pan, preferably made of plastic and / or composite material. Alternatively or additionally, at least parts of the stiffening ribs may also be made of a separate component, optionally of another material such as metal and be connected within and / or outside of the oil pan with this, that a stiffening of the lateral surface and thus a significant stiffening of the lateral surface relative takes place to the Schwingeinflussfläche.

In a preferred embodiment, the area of influence is substantially cylindrical or truncated cone-shaped, in particular with a substantially square, rectangular, circular, elliptical or polygonal base, particularly preferably as a straight cylinder or a straight truncated cone. These geometrical shapes make it possible to determine an influence range that can be determined simply and reliably with regard to its acoustic properties, so that its reaction to the fundamental vibrations of the oil sump can be easily adjusted and the resulting vibrations can be influenced in a targeted manner

It has proven to be advantageous if the maximum offset of the oscillating influence surface to the main extension plane of the side surface assigned to the influence region to the maximum width of the oil pan is a ratio in the range of 1: 4 to 1:12, preferably in the range 1: 5 to 1:10 , more preferably in the range 1: 6 is 1: 9. Alternatively or additionally, it is advantageous for effective areas of influence if the maximum offset of the oscillating influence surface to the main extension plane of the side area assigned to the influence region to the maximum length of the oil pan is a ratio in the range of 1:12 to 1:25, preferably in the range from 1:16 to 1:22, particularly preferably in the range from 1:18 to 1:20, the oscillation properties of the oil sump can be influenced well. It has been shown that the design of the influence areas of an oil sump in the ratio ranges described results in a particularly effective effect of the areas of influence and the effect of the areas of influence is in good proportion to the production engineering and the volume of construction consuming effort of the areas of influence.

A further advantageous measure is when the ratio of the accumulated vibrationally influential surfaces of at least one side to the total area of this corresponding side is 1: 8 to 1.0: 1.5, preferably 1: 5 to 1: 2, more preferably 1: 4 to 1 : 3. For a sufficient effectiveness of the influence regions according to the invention, the ratio ranges of accumulated oscillatory influence surface have at least one side to the total area revealed.

Preferably, the oil pan has at least two areas of influence, which are formed differently in their dimensions and / or in their geometry. This can be particularly advantageous if individual areas of influence are designed specifically for certain vibration spectra and to be tuned to achieve the desired vibration behavior or the desired sound radiation of the entire oil pan and possibly taking into account further, forming an assembly elements with the mounted oil pan. This measure makes it easier for the designer to interpret the oil sump acoustically.

Furthermore, the inventive "design" of the oil pan can be facilitated by at least two opposite side surfaces of the oil pan, preferably the longitudinal sides, each at least one influence area is arranged, in particular the at least two opposing influence area identically sized and / or geometrically equal vibration influencing surfaces.

Also, this substantially symmetrical arrangement of the Schwingeinflussbereiche on the oil pan facilitates the interpretation of the response of the oil pan with respect to their sound radiation.

Moreover, it may be advantageous if all areas of influence are arranged in a longitudinal half of the oil pan, preferably in the last third of a longitudinal region of the oil pan, particularly preferably in the last quarter of a longitudinal region of the oil pan. This can be particularly advantageous if the areas of influence are located in the region of the oil sump of an oil sump. The oil sump of an oil sump is typically characterized in that it has a surface portion which is lower in the final assembly state of the sump than adjacent bottom portions of the sump. In most cases, the volume of the oil sump is greater than the volume in other areas of the sump. By providing influence regions, an enlargement of the internal volume is accompanied, so that the influence regions are preferably arranged in the region of the oil sump.

In a further preferred embodiment, the vibration influencing surfaces of at least two influence regions are arranged parallel to one another and / or preferably in a common plane.

For a particularly favorable attachment of markings, the lateral surface of the influence areas, since these are arranged on the one hand at a position exposed by the oil pan and on the other hand stiffened against the Schwingeinflussfläche are formed, so that an irregularity of the wall thickness / thickness due to the marking, does not adversely affect the vibration behavior of the oil sump. A date field, a material name, a country of origin designation, a customer number, a nickname, a manufacturer's logo, a customer change index, a customer logo, an RFID element and / or any other mark that can be visually and / or energy-excited can be used as the marking.

The natural frequency of at least one influence region and / or its oscillation influencing surface is preferably in the range from 100 to 1000 Hz, preferably from 500 to 750 Hz. With these frequency ranges, the psychoacoustic parameters perceived particularly positively in the sense of the invention are amplified by the influence regions.

In the in the drawing figures 1 to 9 illustrated exemplary embodiment of the oil pan according to the invention 1 this includes a floor area 2 , as well as the floor area 2 surrounding side surfaces 3 . 3 ' . 3 '' . 3 ''' , where the side surfaces 3 . 3 '' on the front sides and the side surfaces 3 ' . 3 ''' on the long sides of the oil sump 1 are arranged. The oil pan 1 is with its free end over a circumferential flange area 4 on an internal combustion engine (not shown) connectable, wherein the oil pan 1 at least partially made of plastic and / or composite material is made. On at least one side surface 3 . 3 ' . 3 '' . 3 ''' is the oil pan 1 with at least one sphere of influence 5 . 5 ' . 5 '' . 5 ''' . 5 '''' provided, which has a lateral surface 6 . 6 ' . 6 '' . 6 ''' . 6 '''' and a vibrational influence surface 7 . 7 ' . 7 '' . 7 ''' . 7 '''' includes. Here is the vibration influence surface 7 . 7 ' . 7 '' . 7 ''' . 7 '''' at least partially offset, that is spaced apart from the main extension plane 8th the sphere of influence 5 . 5 ' . 5 ''' associated side surface 3 ' arranged.

The sphere of influence 5 . 5 ' . 5 '' . 5 ''' . 5 '''' Characterized by its deliberately influenced vibration characteristics, in combination with the remaining rocker characteristics of the oil pan 1 to a desired modified vibration characteristics of the entire oil pan 1 leads. Here is the vibration influence surface 7 . 7 ' . 7 '' . 7 ''' . 7 '''' elastic and thus easier vibrationally excitable than the lateral surface 6 educated.

The vibrational influence surface 7 . 7 ' . 7 ''' is in the preferred embodiment substantially parallel to the main plane of extension 8th the sphere of influence 5 . 5 ' . 5 ''' associated side surface 3 arranged. Basically, the vibrational influence surface 7 . 7 ' . 7 ''' but also an angle of 0 ° to 70 ° with the main extension plane 8th lock in.

By doing that the oil pan 1 Made of plastic and / or composite material, it is possible to influence the area 5 . 5 ' . 5 '' . 5 ''' . 5 '''' with its elements 6 - 7 '''' integral with the oil pan 1 train. This allows both production technology overall cost-effective oil pan 1 as well as a structurally easy-to-implement embodiment of the areas of influence 5 . 5 ' . 5 '' . 5 ''' . 5 '''' to the effect that this is the Schallabstrahlcharakteristik the oil pan 1 purposefully influenced.

Alternatively, at least one sphere of influence 5 be formed in several parts, so for example, the lateral surface 6 forming element integral with the tub 1 and the vibrational influence surface 7 detachable as a separate component or preferably insoluble with the lateral surface 6 be connected, for example by soldering, gluing, welding or the like. Also, the oil pan 1 with five influence spells 5 . 5 ' . 5 '' . 5 ''' . 5 '''' provided, which are formed substantially cylindrical and a rectangular base 11 have, cf. 3 and 4 ,

In the in drawing figure 7 shown detailed representation of a graphically horizontally cut sphere of influence 5 is evident that the wall thickness 20 the vibrational influence surface 7 at least partially smaller than the wall thickness 21 the lateral surface 6 , This is one possible measure for the higher elasticity of the vibration influencing surface 7 opposite the lateral surface 6 to reach. In the illustrated embodiment are additionally in the region of the lateral surface 6 stiffening ribs 9 arranged, wherein the vibrational influence surface 7 no stiffening by corresponding stiffening ribs 9 has and thus the Schwingeinflussfläche 7 relative to the lateral surface 6 has a more elastic and "vibrating" behavior. For this purpose, the vibrational influence surface 7 Alternatively, to a lesser extent than the lateral surface 6 with stiffening ribs 9 be provided, it is essential that the vibration influencing surfaces 7 Overall, a more elastic behavior than the lateral surface 6 having.

Next to the stiffening ribs 9 are on the outside of the oil pan 1 reinforcing ribs 10 arranged, cf. 2 , In the illustrated embodiment, the reinforcing ribs meet 10 a dual function, namely once the function as sacrificial ribs against external mechanical influences on the oil pan 1 and on the other hand as a sound-influencing structure, since the reinforcing ribs 10 an irregular chamber structure on the sump 1 and thus form small oscillating surfaces, that of the oil sump 1 affect radiated sound. The core of the sound-influencing structure is to be seen in that with reinforcing ribs 10 provided oil pan 1 has a natural frequency of 200-1000 Hz and the chambers are formed so irregular that at least partially chambers of the oil pan 1 relative to the adjacent to these chambers have such different dimensions and / or geometry that radiated from the chambers airborne sound in the near field mutually reducible and / or extinguishable being an answer to a transient excitement of at least two faces of the chambers provided surface of the component has a correlation of 0.50 to 0.85, preferably 0.60 to 0.70. The reinforcing ribs 10 serve to limit partial areas that have irregular structures and thereby, due to the stochastic distribution of acoustic dipole sources, cause a mutual reduction or extinction of radiated airborne sound in the near field and thus allow in a frequency band no sound radiation (band-stop filter). For this purpose, it is advantageous if the oil pan 1 despite the ribbing has a defined compliance so as to adjust amplitudes in desired frequency bands to produce a certain minimum sound pressure level for these frequencies, preferably in the low range.

In the region of, preferably integral with the sphere of influence 5 '''' is at least one opening 15 arranged, which can serve to receive an oil level sensor and / or to supply the oil return from the oil separator.

The following are for influencing the vibration behavior of the oil pan 1 and in particular the vibration behavior of the sphere of influence 5 with regard to the entire oil sump 1 set out advantageous dimensions and ratios of individual dimensions. The offset 12 the vibrational influence surface 7 to the main extension level 8th in the sphere of influence 5 assigned side surface 3 ' to the maximum width 13 the oil pan 1 a ratio in the range of 1: 4 to 1:11, preferably in the range of 1: 5 to 1:10, particularly preferably in the range of 1: 6 to 1: 9. In absolute terms, it is advantageous if the offset 12 the vibrational influence surface 7 to the main extension level 8th the sphere of influence 5 associated side surface 3 ''' two to 50 mm, preferably four to 20 mm, particularly preferably six to 12 mm.

The in the drawing figures 1 . 3 and 6 shown areas of influence 5 . 5 ' differ both in the dimensioning and in the geometry of their respective vibration influencing surfaces 7 . 7 ' , Due to the targeted unequal interpretation of two areas of influence 5 . 5 ' or their vibrational influence surface 7 . 7 ' These can be tuned specifically to specific frequency ranges, so that the overall radiation behavior of the oil pan 1 is easier targeted interpretation.

On two opposite side surfaces 3 ' . 3 ''' are sphere of influence 5 . 5 '' formed, each with opposite influence areas 5 . 5 '' are the same size and also the same or similar vibration influence surfaces 7 . 7 '' exhibit. In the intervals 16 . 16 ' the spheres of influence 5 . 5 ' . 5 ''' can in the area of the flange area 4 Fixiermittelaufnahmen 17 . 17 ' for connecting the oil sump 1 an internal combustion engine (not shown) may be provided. This will be the spaces between them 16 . 16 ' between the lateral surfaces 6 . 6 ' . 6 ''' used in addition to their acoustic property at the same time as space and supply opening for the fixing (not shown).

In the illustrated oil pan 1 are the spheres of influence 5 . 5 ' . 5 '' . 5 ''' . 5 '''' in an end half, substantially in an end third of a longitudinal end region 18 the oil pan 1 arranged. The base area 11 at least one sphere of influence 5 . 5 ' . 5 '' . 5 ''' . 5 '''' can be rectangular.
