Abstract
The invention is directed to an oil pan for engines or transmissions and/or automatic transmissions, which is made of plastic material or metal and has an integrated suction and/or pressure oil filtration, characterized in that the oil filter is arranged in the oil pan.
Description
An Oil Pan For Engines or Transmissions The invention relates to an oil pan for engines or transmissions and/or automatic transmissions, which is made of plastic material or metal and has an integrated suction and/or pressure oil filtration.
According to prior art, oil filtration in an engine or an automatic transmission is. effected using filters arranged separately outside the oil pan. To this end, the alter, oil pan seal and oil pan are used as single components.
Here, the oil pan either is made of deep-drawn steel or cast aluminum/magnesium.
According to prior art, the oil filters are arranged in a way so as to be easily accessible and replaceable during maintenance works. In most of the cases, this is achieved by arranging the. oil filter housings so as to protrude from the engine level. In order to prevent the required space from becoming too large in size, the oil filter housing size is severely restricted, so that the oil filters have a small filter surface and require relatively frequent replacement.
Another disadvantage is that the space. within the engine compartment in new engine constructions is highly limited in general, and therefore, such bulky constructions are undesirable per se.
It is therefore the technical object of the invention to provide a new construction and arrangement of oil filter housings for engines or transmissions 2 o andlor automatic transmissions, which avoids the above-mentioned drawbacks and allows space-saving accommodation in the engine compartment. In addition, an oil filter in such a housing should have a larger filter surface, so that frequent replacement is not required.
Said technical obj ect is accomplished by arranging the oil filter housing in an oil pan. This pan can be made of metal or a plastic material. The oil filter housing arranged in the pan can be a suction and/or pressure oil filter housing.
The oil pan preferably consists of plastic material.
Such an integration of the oil filter housing in an oil pan is advantageous in that separate arrangement of the oil filter housing in the engine compartment is no longer required; thereby providing more space for other engine components in the engine compartment. Furthermore, the oil pan volume generally remains largely unused, since only part of the volume serves to collect the oil which is not to used during engine operation. Accordingly, a major volume of the oil pan remains completely unused. By integrating the oil filter housing in the oil pan, the unused space is made.useful.
In a preferred embodiment, ribs and has 5 are arranged in the oil pan 1.
The plastic half tray 6 is placed on these ribs and fins, the filter medium 13 being 1 s arranged between the plastic half tray 6 and oil pan 1. In a preferred fashion, the plastic half tray 6 is dimensioned so as to cover only part of the bottom of the plastic oil pan 1. The volume between the plastic half tray 6 and the covered part of oil pan 1 then forms the oil filter housing.
In another preferred embodiment, a filter opening 11 is situated below the 2 o filter medium 13 at the side of the plastic oil pan 1 forming the boundary of the oil filter housing, which opening is used as oil inlet 9 or oil outlet 10.
Another oil inlet 9 or oil outlet 10 is situated in the upper part of plastic half tray 6, encircled by a sealing element 8.

In a preferred embodiment, ribs and has 5 are arranged in the oil pan 1.
The plastic half tray 6 is placed on these ribs and fins, the filter medium 13 being 1 s arranged between the plastic half tray 6 and oil pan 1. In a preferred fashion, the plastic half tray 6 is dimensioned so as to cover only part of the bottom of the plastic oil pan 1.

In another preferred embodiment, a filter opening 11 is situated below the 2 o filter medium 13 at the side of the plastic oil pan 1 forming the boundary of the oil filter housing, which opening is used as oil inlet 9 or oil outlet 10.
Another oil inlet 9 or oil outlet 10 is situated in the upper part of plastic half tray 6, encircled by a sealing element 8.
In addition to said opening, a second filter opening maybe arranged in the plastic half tray 6 in another embodiment.
For improved securing and positioning of the filter medium 13, support ribs 15 are molded on the plastic oilpan 1 or the plastic half tray 6. Flow ribs 16 are arranged within the oil filter housing to produce a directional oil flow.
The welded joint between filter medium 13 and plastic half tray 6 is denoted by numeral 14. By molding the support ribs 15 either on the oil pan 1 or the plastic half tray 6, deformation of the plastic half tray 6 during suction is avoided.
The Figures below are intended to illustrate the invention in more detail.
Figure 1 shows a cross-sectional view of the oil pan according to the invention with laterally arranged oil inlet/oil outlet.
Figure 2 shows a cross-sectional view of the oil pan according to the invention with oil inlet/oil outlet arranged on top.

To seal against the engine or transmission housing 4, an 2 o elastomer seal 3 is lined in a groove extending along the oil pan outer edge or spray molded on the outer edge in a separate procedure.
The seal 3 is. accommodated by molding a groove 17 in the oil pan 1. The screw connection to the engine or transmission housing 4 is accomplished by screw-on sockets, the screw forces being transmitted to the housing via a metal j acket. The seal contour extends bilaterally around the screw-on socket.
Inside the oil pan 1, contours in the form of ribs and fins 5 are molded, allowing a second plastic half tray 6 to be connected with oil pan 1. This plastic half tray 6 serves as an oil filter housing cover. The bottom of the oil filter housing is formed partially or completely by the bottom of the oil pan. The. welded joint between the plastic half tray 6 and the oil pan 1 is produced using vibratory 1 o friction welding, particularly orbital vibratory friction welding, circular vibratory friction welding, or ultrasonic or laser welding methods.
In order to obtain the filter function, a filter medium 13 is previously placed between the plastic oil pan 1 and the plastic half tray 6 prior to welding at welding spot 7 and mechanically fixed and held during the welding process.
Such a design allows integrating an oil filter in the oil pan, which functions as a suction or pressure oil filter.
Sealing against the engine/transmission oil pump is effected by a sealing element 8, preferably a spray-molded mufti-lip seal, a separately pressed-on mufti-lip seal, O-rings, or special sealing elements.
2 o Depending on use and application, the oil inlet 9 and oil outlet 10 of the integrated oil filter are to be designed in a way allowing to form a suction and/or pressure oil filter with appropriate function. Depending on the demanded function, oil flow directions into or within the filter are possible by lateral arrangement of the filter openings 11.

Figure 2 shows a cross-sectional view of the oil pan according to the invention with oil inlet or oil outlet arranged on top:
Figure 2 shows an alternative embodiment of the oil pan according to Figure 1. In Figure 2, the filter opening 12 is arranged in the plastic half tray 6.
When suction from the top through filter opening 12 is required; the filter medium 13 must be welded tightly to the upper plastic half tray 6 at point 14 using ultrasonic or vibratory welding methods. In order to reduce deformation of the filter tray 6, support ribs 15 can be molded either on plastic oil pan 1 or plastic half tray 6. The filter medium 13 then rests on said support ribs 15, l o thereby obtaining additional stability. Directional oil flow within the filter is produced by flow ribs 16. The filters are designed according to the lifetime of the engine/automatic transmission unit.
Using the oil pan according to the invention, a space-saving alternative to a conventional arrangement of an oil filter in an engine compartment is provided.
By using large surface filter media, oil filters can be employed that are adjusted to the lifetime of engine and/or transmission unit, so that frequent replacement of oil filters is not required.
With respect to its filter surface, the oil pan of the invention can be designed in such a way that replacement of the filter during the average lifetime 2 0 of the respective vehicle is no longer required.
It is another advantage that the space within the oil pan, which has not been utilized anyway, now is made useful, and that space is gained by relocating the oil filter from the engine compartment.
