Abstract
An oil filter of a transmission for motor vehicles has one filter housing, at least one inlet opening for unfiltered oil, at least one outlet opening for filtered oil. A filter medium is arranged in the oil flow between the at least one inlet opening and the at least one outlet opening. The filter housing is formed from two shells connected with one another, a lower shell and an upper shell, and features a second outlet opening.
Description
- The invention relates to an oil filter for a transmission for motor vehicles.
- Known oil filters for motor or transmission oil feature a filter housing, which consists of two half shells connected with one another on the circumference and a clamped filter medium. The filter housing features one inlet chamber for unfiltered oil and one outlet chamber for filtered oil, whereas the inlet and outlet chambers are separated by the filter medium. With suction filters, the unfiltered oil is sucked through the filter medium, and thereby cleaned.
- DE 197 35 445 A1 discloses an oil filter with a filter housing that is integrated into the oil pan of the transmission. The known oil filter features two chambers, namely one inlet chamber for unfiltered oil and one outlet chamber for filtered oil. The inlet chamber is formed on its underside through the bottom of the oil pan, while the outlet chamber is formed by a plastic half shell. A filter medium is clamped between the inlet chamber and the outlet chamber. The inlet opening for unfiltered oil is located at the bottom of the oil pan, while the outlet opening is formed through a spout of the upper plastic shell.
- Problems of designing an oil filter may arise when there are special installation conditions, for example, if two outlet openings for the oil filter are necessary and, at the same time, there are mounting obstacles or only confined installation space is available.
- It is a task of the present invention to take into account such problems of conventional oil filters through an appropriate design of the oil filter. Additional objects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention.
- The tasks of the invention are solved by the characteristics of advantageous designs according to the claimed invention.
- In accordance with the invention, the housing features two half shells connected with one another, preferably made of plastic, namely a lower shell and an upper shell, whereas one inlet opening is located in the lower shell, and two outlet openings are located in the upper shell. The two outlet openings, the spacing of which from each other is indicated, are provided for different suction connections.
- According to a preferred embodiment, a first chamber for unfiltered oil is formed by the lower shell, and a second and third chamber for unfiltered oil, each of which is allocated an outlet opening, is formed by the upper shell. Thus, the filter housing has one inlet chamber for unfiltered oil and two outlet chambers for filtered oil, whereas the filter medium overlays the inlet chamber. For the upper shell, given the two outlet chambers arranged next to each other, a larger width arises than that of the lower shell, which features only one inlet chamber.
- According to a further preferred embodiment, the filter medium is clamped on the circumference between the inlet chamber in the lower shell and the first outlet chamber in the upper shell. The filter medium, for example a membrane, does not extend across the entire width of the upper shell, which results in a savings of material and costs.
- According to a further preferred embodiment, both the lower shell and the upper shell have a circumferential flange for the firmly bonded connection of both shells, whereas a bridge flange is arranged between the two outlet openings and the circumferential flange of the upper shell, which clamps with sealing effect the filter medium between itself and the lower shell. This ensures that the filter medium is clamped around the area of the inlet chamber.
- According to a further preferred embodiment, the bridge flange is connected with the upper shell through bars that are left between the flow-through openings. Two functions are achieved through this; i.e., on the one hand, the clamping of the filter medium between the upper shell and the lower shell and, on the other hand, the formation of a flow cross-section between the two outlet chambers in the upper shell.
- According to a further preferred embodiment, an intermediate flange of the lower shell is allocated to the bridge flange of the upper shell. With the circumferential flange of the lower shell, the intermediate flange forms a continuous sealing layer for the clamping of the filter medium.
- According to a further preferred embodiment, the filter housing in the area of the second outlet chamber features an installation height, reduced by the amount ΔH, vis-à-vis the installation height H in the area of the inlet chamber and the first outlet chamber. The lower shell features a recess in the area of the bridge flange, and runs from the bridge flange up to the outer flange, approximately to the flange layer. This gives rise to the mentioned reduction in the installation height below the second outlet chamber, i.e. below the second outlet spout.
- According to a further preferred embodiment, the two outlet openings in the upper shell are formed as spouts. Thus, it is possible to produce a simple plug-in connector with the oil connection lines.
- According to a further preferred embodiment, the oil filter is able to be operated as a suction filter for two oil pumps. The suction spouts of the oil pumps feature the same spacing as the outlet spouts of the filter housing, and thus may be installed relatively easily through plugs.
- One embodiment of the invention is shown in the drawing and more specifically described below, whereas additional characteristics and/or advantages may arise from the description and/or the drawing. The following is shown:
-
FIG. 1 is an oil filter under the invention with two output spouts and a partially reduced installation height; and -
FIG. 2 is a section in the area of level II-II inFIG. 1 . - Reference will now be made to embodiments of the invention, one or more examples of which are shown in the drawings. Each embodiment is provided by way of explanation of the invention, and not as a limitation of the invention. For example features illustrated or described as part of one embodiment can be combined with another embodiment to yield still another embodiment. It is intended that the present invention include these and other modifications and variations to the embodiments described herein.

FIG. 1 shows anoil filter 1, which is able to be used for transmissions of motor vehicles, and can be arranged in the area of an oil pan of the transmission, which is not shown. Theoil filter 1 comprises afilter housing 2, which is constructed of two shells, namely alower shell 3 and an upper shell 4. Thelower shell 3 features acircumferential flange 3 a and aninlet opening 5, which is arranged in the lower area of thelower shell 3. The upper shell 4 likewise features acircumferential flange 4 a, which has a firmly bonded connection with sealing effect with theflange 3 a of thelower shell 3, for example by means of welding. In the upper shell 4, two outlet openings formed asspouts bridge flange 8 is connected in one piece throughbars 9. Thelower shell 3 features a trough-like inlet chamber 10, which is limited upwards through afilter medium 11, preferably formed as a membrane. Through the upper shell 4, afirst outlet chamber 12 and asecond outlet chamber 13 are formed; these are in a flow connection with one another through the flow-through openings (seeFIG. 2 ) between thebars 9. Thefirst outlet spout 6 is allocated to thefirst outlet chamber 12, and thesecond outlet spout 7 is allocated to thesecond outlet chamber 13. Thefilter medium 11 is clamped between thelower shell 3 and the upper shell 4; on the one hand, between thecircumferential flanges bridge flange 8 and acorresponding flange area 3 b of thelower shell 3, called theintermediate flange 3 b. Thesecond outlet chamber 13 is closed by afloor 3 c, which is a part of thelower shell 3. -
FIG. 2 shows a section in level II-II, marked inFIG. 1 . Thebridge flange 8 extends between thecircumferential flange 4 a of the upper shell 4, and with thecircumferential flange 4 a forms a continuous sealing layer. Analogously, theintermediate flange 3 b is molded on thelower shell 3; this passes into the outer areas of thecircumferential flange 3 a. Thefilter medium 11 is clamped with sealing effect between thebridge flange 8 and theintermediate flange 3 b. Between thebars 9, which serve the purpose of reinforcing thebridge flange 8, the flow-throughopenings 14 are left, through which the filtered oil flows from thefirst outlet chamber 12 into thesecond outlet chamber 13. - The design of the
filter housing 2 is intended for two separate suction connections, preferably two suction spouts of oil pumps that are not shown. The spacing of the output spouts 6, 7 marked with “a” inFIG. 1 , is predetermined. This gives rise to a predetermined width for thefilter housing 2. On the other hand, this width in the area of thelower shell 3 cannot be adhered to for installation reasons. The maximum installation height of thefilter housing 2—without outlet spouts 6, 7—corresponds to the installation height of theinlet chamber 10 and thefirst outlet chamber 12, and is indicated in the drawing with H. In contrast, the installation height of thefilter housing 2 in the left area of the drawing, i.e. within thefloor 3 c of thesecond outlet chamber 13, is reduced by the dimension ΔH. Given the predetermined installation conditions, thefilter housing 2 in this area may be left out; on the other hand, the predetermined distance a between the two outlet spouts 6, 7 was adhered to. - The
lower shell 3 and the upper shell 4 are preferably made of plastic, and each are formed as molded parts. - The oil flow takes place—according to the flow arrows in FIG. 1—in the manner that initially unfiltered oil (which was collected in a pan that is not shown) enters through the
lower inlet opening 5 into theinlet chamber 10, and is extracted from there upwards through thefilter medium 11. Then, the filtered oil initially arrives in thefirst outlet chamber 12, from where the oil flow branches out: one part is extracted through theoutlet spout 6 with a first pump, and another part flowing through the flow-through openings 14 (seeFIG. 2 ) arrives in thesecond outlet chamber 13, and from there is extracted through theoutlet spout 7 of a second pump. Thus, theoil filter 1 is preferably operated as a suction filter. Theinlet opening 5 arranged in the floor area inFIG. 1 may also be provided in a side wall of thelower shell 3. - Modifications and variations can be made to the embodiments illustrated or described herein without departing from the scope and spirit of the invention as set forth in the appended claims.
