- Such a supply device may have a controllable injector, with which it can be adjusted whether the exhaust gas treatment device additive is supplied.
- an apparatus for providing a liquid additive in a motor vehicle is an additional supply system, it is important that the apparatus be particularly robust and at the same time inexpensive.
- the manufacture of the device and the components and materials used should be particularly cost-effective. At the same time, it should also be possible with as little effort as possible to achieve or replace individual components of the device for maintenance.
- the invention relates to a device for providing a liquid additive, comprising at least one tank and a removal unit for conveying the liquid additive from the tank to an additive consumer, wherein the tank has at least one tank wall and the extraction unit is mounted to a mounting portion of the tank wall, said Tank wall made of injection-molded material and in the area of the assembly-cut integrated stiffening s structures are provided in the injection molding compound.
- the tank of the device has an internal space in which the liquid additive is stored in the tank.
- the interior of the tank is bounded by the tank wall.
- the tank wall typically has an area that can be considered as a tank top, as well as an area that can be considered as a tank bottom.
- the removal unit removes the liquid additive from the tank at a removal point, which is preferably arranged in the vicinity of the tank bottom or on the tank bottom itself. With this arrangement, it is possible with the removal unit, the contents of the tank - that is, the liquid additive - to remove completely from the tank. It is also possible that several removal units are provided.
- the removal unit preferably has a plurality of active components which take over the delivery of the liquid additive and optionally also the metering of the liquid additive.
- active components may comprise, for example, the following elements: at least one pump which pumps and / or doses the liquid additive, at least one valve which controls the delivery and / or the dosage, at least one sensor with which the delivery and / or the dosage are monitored can be filtered, at least one filter with the liquid additive provided by the device.
- the removal unit is preferably mounted on the tank wall of the tank.
- various fastening elements are provided on the tank wall, with which the active components can be interconnected.
- the tank wall thus forms a kind of base plate or a kind of mounting plate for the removal unit.
- the portion of the tank wall on which the extraction unit or the components of the extraction unit are mounted is referred to as a mounting section.
- the mounting portion thus extends substantially only over a region of the tank wall, on which the active components or, for example, a housing of the extraction unit is provided.
- the mounting portion of the tank wall ends with an outer (circumferential) edge for example, a maximum of 10 cm or even a maximum of 5 cm [centimeters] around the extraction unit.
- the tank wall preferably has an indentation.
- the indentation preferably extends from an outside into an interior of the tank.
- the indentation preferably forms a portion of a housing of a chamber, which is separated from the interior of the tank.
- this chamber is dry or free of liquid additive.
- the removal unit is mounted to the mounting portion, the mounting unit is preferably located (particularly completely) within the chamber formed by the indentation.
- the chamber or the indentation can preferably be sealed from an outer side of the tank with a lid. Thus, the extraction unit can be protected in the chamber from contamination from the outside.
- the tank wall is made of injection-molding compound and in the region of the mounting section stiffening structures are integrated into the injection molding compound.
- the injection molding compound consists for example of polyethylene (PE), polypropylene (PP) or polyoxymethylene (POM).
- PE polyethylene
- PP polypropylene
- POM polyoxymethylene
- HD-PE high density, high density
- the suitability for tanks for the storage of common liquid additives has been proven. Due to the fact that the tank wall or the tank consists of injection-molding compound or has been produced by means of an injection molding process, it is possible for the tank to have particularly complex geometries. For example, the tank may have indentations, protuberances, undercuts and similar geometric shapes. It is possible that the entire tank wall of the tank is made in a single injection molding process. It is also possible that the tank consists of two half-shell-shaped tank sections, which are welded together and thus form the entire tank.
- the tank is made of an upper shell and a lower shell, which are interconnected by a circumferential weld.
- the shrinkage phenomenon can be reduced because the shrinking injection molding material is partially replaced by the stiffening structures.
- the shrinkage that occurs can be aligned so that the shrinkage does not unduly influence the tolerances required for mounting the removal unit in the assembly section.
- the at least one stiffening structure is integrated or incorporated into the injection molding compound.
- the stiffening structure is to a large extent or even (practically) completely surrounded by the injection-molding compound ("integrated") -
- the stiffening structure is added or inserted into the injection-molding compound, in particular during the production of a tank wall If a stiffening structure (possibly of complex design and comprising several subcomponents) can be provided, the use of a multiplicity of (separate or separate) stiffening structures is preferred.
- the number and / or orientation of the stiffening structure can be the structure or arrangement of the active components in the mounting section ("anisotropy" over the mounting section). But it is also possible that the stiffening s structures are provided uniformly over the mounting portion ("isotropy" on the mounting portion).
- Providing stiffening structures in the region of the mounting section therefore makes it possible to use an injection molding tool even with considerably higher tank frequencies and to allow faster cooling rates. allow and at the same time to comply with manufacturing tolerances very precisely in the area of the mounting section.
- the device when the mounting portion is connected to a further tank wall by a weld.
- the mounting section preferably represents a wall section produced independently of the rest of the tank.
- the mounting section and the further tank wall are preferably produced in separate injection molding processes.
- the further tank wall preferably has an opening into which the tank wall can be used with the mounting portion.
- the mounting section and the further tank wall are then preferably connected to one another by a welding method, so that a weld seam is formed between the tank wall with the mounting section and the further tank wall.
- the described additional stiffening s structures can be inserted into the injection molding compound. It is also possible to produce the mounting portion and the further tank wall with different cooling rates after injection molding. Thus it can be achieved that the shrinkage in the region of the mounting section is significantly smaller than in the remaining tank wall.
- the device is advantageous if the tank wall has stiffening structures integrated in the area of the mounting section only and the further tank wall has no stiffening structures.
- the further tank wall and stiffening structures and in particular stiffening fibers are included.
- the proportion and the stiffening effect of the stiffening structures in the further tank wall are only considerably smaller than the proportion and stiffening effect of the stiffening structures in the area of the assembly section.
- the resulting stiffnesses (ie the stiffness of the injection molding dimensions with stiffening structures) in the region of the Montageab- section is at least twice as large as the rigidity of the other tank wall.
- connection element for connecting at least one component for conveying or metering the liquid additive is provided on the mounting section.
- a connection element is preferably a fluidic connection element which forms a connection between the interior of the tank and an active component or between two different active components of the extraction unit.
- a connecting element may, for example, consist of an (integrated) tube and / or an (integrated) socket and / or an (integrated), possibly electrical, plug, which are integrated into the tank wall in the region of the mounting section.
- a connection element can be inserted, for example, into the injection mold and firmly joined to the injection molding compound of the tank wall or the assembly section by the injection molding process. To provide such connection elements in the mounting portion, simplifies the assembly of the extraction unit to the mounting portion.
- the device is advantageous if the integrated stiffening structures comprise stiffening fibers.
- Stiffening fibers can be incorporated into the injection molding compound in the area of the mounting section and directly incorporated in the injection molding process.
- Stiffening fibers can be, for example, glass fibers and / or carbon fibers, which for example have a fiber length in the range from 1 cm [centimeter] to 4 cm.
- Stiffening fibers represent a particularly cost-effective way to integrate stiffening s structures in the region of the mounting portion in the tank wall, because only a modification of the injection molding compound for the mounting portion is required lent and no separate preparation of the injection molding tool must be done by, for example, the stiffening s structures in the injection mold are inserted.
- the device is advantageous if the stiffening fibers make up a proportion by weight of between 5 percent and 40 percent of the assembly section.
- the proportion of stiffening fibers is in the range between 5 percent and 20 percent and more preferably about 10 percent.
- the proportion by weight here refers only to the tank wall in the region of the mounting section, wherein the weight fraction between 5 percent and 40 percent relates only to the weight of the injection molding compound together with the stiffening fibers and any additional components (such as in the mounting section embedded or cast-in connection elements) not to be considered with.
- Such a proportion by weight of the stiffening fibers makes it possible to provide a particularly dimensionally stable tank wall in the region of the mounting section which particularly accurately complies with predetermined tolerances.
- an injection molding compound with such a proportion by weight of stiffening fibers is easy to process.
- the device is advantageous if the integrated stiffening structures comprise at least one stiffening mat.
- a stiffening mat may for example be a fiber mat, which may for example consist of glass fibers and / or carbon fibers.
- the stiffening smatte may consist of a structured fiber fabric and / or of a stochastic fiber tangle (a fleece).
- Such a stiffening mat can, for example, be inserted into an injection mold in the area of the mounting section and surrounded or encapsulated by the injection molding compound during the injection molding process.
- Such a stiffening structure made of a stiffening mat enables a particularly Accurate compliance with tolerances and a particularly strong stiffening of the mounting section, because the orientation of fibers is precisely specified in such a stiffening mat and thus the mechanical influence of the stiffening mat on the mounting section can be determined very accurately. It is also possible for layers and / or regions to be formed with a plurality of (possibly different) fiber mats.
- the device is advantageous if the integrated stiffening structures comprise at least one stiffening grid.
- a stiffening grid can also be inserted into the injection mold before the injection molding process and surrounded by the injection molding compound during injection molding.
- a (self-stable) stiffening grid acts much like a stiffening mat.
- the stiffening grid can be, for example, a metallic wire mesh.
- Such a grid has the additional effect that the tank wall in the region of the mounting portion has an improved thermal conductivity, which allows heat (for example, emanating from a heater) is better passed through the mounting portion.
- connection elements described above are firmly connected to a stiffening grid.
- an insert is inserted into the injection mold, which consists for example of the stiffening grid and attached to the stiffening grid connection elements. This insert is then only partially surrounded by the injection molding compound.
- the stiffening grid itself should in this case be completely surrounded by the injection-molding compound, while the connection elements can protrude from the injection-molding compound.
- For a fixed connection between the connecting elements and the stiffening grid is also given a particularly good heat transfer between the connection elements and the stiffening grid.
- a preferred method for producing the device described is also intended to be given here. This includes at least the following steps:
- the tank with the tank wall and the opening (step a)) is manufactured separately from the mounting section (step b)). This is preferably done with separate injection molding tools.
- the connection of the mounting portion with the tank or the other tank wall then takes place in steps c) and d).
- This method enables a particularly cost-effective and simple che production of a tank having a stiffened tank wall in the region of the mounting portion.
- the tank does not need to be manufactured as a complete part in step a). It is also possible that several sections of the tank are manufactured with separate injection molding and also with the aid of welding process are connected to each other.
- a friction welding is applied, wherein the mounting portion relative to the other tank wall is moved in the manner of a rotation.
- the rotation does not have to be a complete rotation.
- the mounting portion in the region of the opening only a few angular degrees is moved back and forth.
- the material of the tank wall is melted in the region of the circular outer edge or in the region of the opening and the mounting portion permanently and firmly connected to the tank wall.
- a modification is to be specified here, in which for the production of the mounting portion of the tank wall in step b) a different injection molding compound is used as for the production of the other tank wall in step a).
- the injection molding compound for step b) preferably has a higher strength and allows more accurate processing while maintaining more accurate tolerances than the injection molding compound for step a).
- step a) then even on separate stiffening s structures are omitted in the mounting section.
- the stiffening structures are then formed by the special injection molding for the mounting section. Accordingly, a device is also possible which has a different injection molding compound in the region of the mounting section than in the region of the further tank wall. Important prerequisite for this, however, is that the various injection molding compounds are weldable together so that the mounting portion of the tank wall and the other tank wall can be connected together.
