Definitions
- Such an oil pan is from DE 197 35 445 A1 known.
- the circumferential survey serves as a support for a flat filter element, which of an attached Half shell is braced against the elevation.
- a complete oil filter which connected to an oil pump into the oil pan integrate.
- the filter element is designed so that its Service life of the assigned engine or Gearbox corresponds.
- the invention is therefore based on the object Oil pan of the type mentioned to create the better is able to absorb external forces.
- Oil pan according to the invention characterized in that the means for absorbing external forces have webs that in addition to the known ribs on the outside are arranged at least of the tub bottom, the Bridges at least as far as the ribs protrude and one have higher rigidity than the ribs.
- the invention is based on the knowledge that a optimally designed oil pan must be able to both withstand dynamic as well as static loads, the dynamic loads mainly from rockfalls are caused during the static loads during assembly by the weight of the overlying Motors or transmissions are created, namely if the from Oil pan and aggregate existing block rests on the oil pan and possibly even postponed.
- the static loads are used for the Oil pan according to the invention the webs with their high rigidity.
- the ribs however, protect the oil pan from falling rocks. In this respect they have the same function as the known ones Ribs out, but to an improved extent, because namely the ribs of the oil pan according to the invention a diminished Have rigidity.
- the reduced rigidity of the ribs namely causes the energy of the striking stones only introduced to a small extent into the bottom of the oil pan becomes.
- the main part of the energy is caused by elastic deformation the ribs dismantled.
- the ribs are in the direction of travel of the vehicle. Meets a stone on the Bottom of the oil pan, so he pushes himself into the space between two neighboring ribs, pushes them apart and simultaneously migrates in the longitudinal direction of the ribs, the Deformation of the ribs migrates while the ribs are behind return the stone to its original shape.
- the stiffer webs serve to accommodate the static loads during assembly. They preferably stand farther than the ribs in front to the latter, as more sensitive trained to protect against mechanical loads, as they occur especially when the oil pan is full Motor or gear is pulled over the floor. Furthermore is it is advantageous to align the webs parallel to the ribs.
- the webs can be made of the same material as the ribs consist. They will then be made wider than the ribs. There is also the possibility for the webs and the Ribs to use different rigid materials.
- the material is a thermoplastic used, especially a polyamide, preferably one with glass fiber reinforcement.
- the different Stiffness of the ribs and webs is here due to the Set the choice of material thickness.
- Polyamide is temperature resistant, oil resistant and hard. Because of the stable bridges you can work with relatively thin-walled ribs.
- the processing of the fiber reinforced polyamide is equally possible in the pressing process, preferably in the strand filing process.
- Strands can different content of reinforcing fibers with each other be combined. This in turn leaves different stiffnesses the webs and ribs too.
- the attachment of the oil pan to the associated engine or Transmission takes place via the side wall of the oil pan, whereby these are usually provided with a circumferential flange is.
- the one from the Support forces absorbed by webs can thus be used in terms of strength conveniently derived over the side wall become.
- the bars can also be parallel to Side wall directly on the flange or at a distance from the side wall connect to the tub floor. You should, however transmit the forces in a favorable way.
- this serves on the inside of the bathtub floor as a support for the flat filter element.
- you get the training so hit that a section of the elevation of one level is formed in the side wall of the oil pan.
- the survey forms a support on one and the same level.
- the survey is a deepening of the tub floor passes through and at the location of the recess an oil passage opening has, the end crossing the oil passage opening Bridge of the pillar with the tub floor connected is. The deepening of the tub floor provides sure that the oil outlet is at the lowest point of the Oil pan is located and therefore always below the oil level lies. The penetration of air is reliably prevented.
- the pillars form a stabilization the elevation, which at the location of the oil passage opening in remaining cantilever bridge.
- the bridge supported over the pillars is one optimum shielding of the filter element in terms of strength against external loads.
- the deepening in the tub floor is like this design deep as possible. It is preferable to choose a wedge-shaped contour in cross-section on the outside of the tub floor with its chisel tip, which is on the Locations of the interior elevation located at the height the ribs lie if it is an oil pan with ribs is.
- the oil pan according to FIGS. 1 and 2 has a pan floor 1, which is connected to a circumferential side wall 2 is. Furthermore, the tub floor 1 carries a circumferential elevation 3, on the left edge in Fig. 1 by a step 4 of the side wall 2 is formed, but otherwise the shape of a wall has.
- the revolving survey 3 serves as a support for a flat filter element, which from an upper half-shell is braced against the elevation 3.
- the upper half-shell is connected to an oil pump. That is how it is Oil filter integrated in the oil pan.
- the tub base 1 carries a plurality on its underside of ribs 5, which are aligned in the direction of travel. They protect the tub floor from falling rocks. This is in Considering that there are cracks in the filter element must be avoided. An exchange of the filter element is not intended.
- Hitting stones penetrate into the spaces between the ribs and lay a distance there in the longitudinal direction of the ribs back, causing elastic deformation the ribs come. This causes the impact energy degraded without endangering the filter element.
- the entire assembly can also can also be pushed back and forth on the webs 6.
- the webs 6 serve, predominantly bear static loads.
- the webs 6 stiffer than the ribs 5.
- the different Stiffness is achieved in the present case in that the ribs 5 have a smaller wall thickness than the webs 6, see Fig. 2.
- Fig. 2 shows that the webs 6, which run parallel to the ribs 5, continuations form the circumferential side wall 2. The supporting forces are therefore introduced directly into the side wall 2 by the webs 6, So in the area in which the oil pan is attached to the associated engine or gearbox.
- the tub floor 1 according to FIGS. 1 and 2 has a recess 7, which represents the lowest point of the oil sump.
- the recess 7 is traversed by the survey 3, the latter at this point having an oil passage opening 8 having.
- the oil passage opening 8 is therefore always flushed, so that the oil pump cannot suck in air.
- the elevation 3 forms above the oil passage opening 8 a bridge 9, which, as can be seen from FIG. 2, over Pillar 10 on the tub floor 1, namely in the recess 7, supports. This stabilizes the support for the flat Filter element.
- the oil pan according to FIGS. 1 and 2 as a one-piece Injection molded part is made of polyamide, which is 3 from polypropylene
- the bottom of the pan 1 on its underside a coating 11 made of a thermoplastic Elastomer carries.
- the coating 11 has sufficient elasticity to withstand the impact energy of Rockfall without endangering the flat filter element absorb.
- the static forces are also from here Bars 6 added.
- the ribs 5 and the webs 6 made of different materials exist, but with the proviso that the rigidity the webs 6 is larger than that of the ribs 5. Also can, as shown, with one and the same material work, the different stiffness due to differences the reinforcing fibers (fiber material, length, -quantity) is achieved. Furthermore, the various measures can be combined with each other. Own all materials adequate temperature resistance and oil resistance. 3 is the temperature resistance of the polypropylene through the inclusion of extremely long reinforcement fibers achieved. The rigidity of the oil pan shouldn't be too great to prevent annoying noise. The distance between the ribs and webs can be varied.
