Background technology
As known in the B1 of EP 2 029 865 it is a kind of as motor vehicle working liquid tank.Set on the medial surface of this tank
It is equipped with the fastening plates or base plate by the tank opening covering on the bottom of tank.Base plate is the group of the outermost shell of tank
Constitute into part and thus a part for tank skin.Base plate has the outlet that a working solution can flow through.In addition, on base plate
It is provided with least one functional part.Additionally, base plate can have a cavity, thus base plate wall section tank inner chamber is divided into it is many
Individual partial volume, wherein at least one functional part can be arranged in this cavity.According to the theory of the B1 of EP 2 029 865
The quantity for the necessary installation step being arranged on functional part on tank skin can in the following way be reduced, i.e., it is all of
Functional part is arranged on base plate.Therefore the assembling of functional part is only limitted to the work(together with all settings on which floor plate by base plate
Energy part is arranged on tank skin as the functional part component of prepackage.But therewith tank known to the B1 of EP 2 029 865
Simplified assembling and come be design flexibility in structure forfeiture.
Generally for a thing of the functional part component on tank of the base plate or prepackage being well known in the art
An installation constitution is provided with the infield first defined.It is not total yet with the structure space regulation in motor vehicle
The functional part component of prepackage can be arranged on being set on the installation constitution on the infield for defineing in advance on tank.
Additionally, such functional part-these functional parts are due to their physical action principle and their use mesh
The reason in order to perform their working solution conveying or/and purification or/and performance detection or/and performance change it is complete
U.S. intact function (such as one capacitance level transducer or a condenser type mass sensor) requires mutually different
Orientation-must be arranged on base plate as follows, i.e., they to be to define in advance, the relatively expected work occurred in tank inner chamber
The orientation on liquid surface is arranged in the base plate being assemblied on tank.If board structure is into if flat wall member, by each work(
The possibility that energy part is arranged in mutually different orientation is restricted.Although can be carried out more to this in the following way
Mend, that is, the base plate with the assembling section for setting with inclining towards each other is provided, each functional part can be in orientation different from each other
In be arranged on these assembling sections on.But therefore increased complexity and therefore increased the cost of base plate.In addition, these are filled
Then standby section is usually fully located inside tank.Further, since the limited area of base plate may cause each functional part
Mutual influence.
In addition, must take into consideration great number in the case of the one or more functions part fails of the functional part component of prepackage
Maintenance cost because prepackage functional part component be located at tank inner chamber in and therefore have to be completely disassembled.
This point shows：The functional part component of the prepackage of prior art is in the situation by functional part configuration on tank
In only allow the construction space of very little.
The content of the invention
In this context, it is an object of the invention to provide the motor vehicle working liquid tank that a kind of literary head addresses type, the machine
Motor-car working liquid tank makes the designer of such tank have more setting without shortcoming well-known in the prior art, and particularly

In order to realize that this purpose present invention is proposed：Multiple functional parts of tank are arranged on the tank skin for setting with being mutually inclined
Duan Shang.The prepackage for the part that can abandon need to being individually mounted on tank skin and then constitute the tank skin in this way
Functional part component.Therefore can by functional part by simple mode the physical action principle with them and they
The corresponding tank skin section for setting with inclining towards each other is arranged in the orientation that application target is consistent above and each single work(is so ensured
The perfect function of energy part.Therefore each functional part is not limited to be arranged on functional part component for prepackage
In limited region.Therefore functional part set with can each other keeping larger spacing, can reduce in this way or
Even exclude the mutual influence of each functional part.So each functional part can be arranged on what is set with inclining towards each other
On any position in tank skin section.Plurality of functional part is arranged on tank skin by multiple installation constitutions.By fully profit
With the same such tank skin section for setting with inclining towards each other, each functional part can be arranged on tank skin with motor vehicle in be available for
On the position that the structure space and the shape of tank for using match.The single setting of each functional part makes each single work(
The particularly effective action principle of energy part is possibly realized.
The functional part that the conveying or/and purification or/and nature examination or/and property for being configured for working solution change can
Selected with from a group, the group includes：One pressure sensor for being used to detect the pressure in tank；One is located at for detection
The liquid level sensor of the liquid level of the working solution in tank；One is used to detect the temperature of working solution or/and the temperature of external environment condition

Put；One conveying device for being used for transportation work liquid；One filter for being used for filtration liquid；It is used to recognize position with one
The sensor of the cavity in the working solution for freezing in tank inner chamber.
If for example a capacitance level transducer and a condenser type mass sensor are arranged on tank skin,
So with the working solution surface in tank should be vertically arranged liquid level sensor and mass sensor is abreast set.According to this hair
It is bright, the mutual shadow of capacitance level transducer and condenser type mass sensor can be simply excluded in the following way
Ring, will two sensors be arranged on the ground that inclines towards each other, in tank skin section particularly perpendicular to one another.
Because functional part arbitrarily can be arranged on tank skin, to the selection of the particular type of certain functional part not
By or only limited by very little.
In the case of liquid level sensor, for example, capacitance type liquid level measuring can be used, using the level gauging of ultrasonic wave
Or other physical measuring methods for detecting liquid level.
The property of working solution for example refers to the temperature of working solution, quality-for example pass through its chemical analysis or/and by changing
The share performance-of the material in studying point or pressure etc. are such.
The concept of tank skin should be as follows understood in the present invention：The medial surface of tank skin and tank inner chamber border and tank skin it is outer
Side and the external environment condition border of tank.It is preferred that the medial surface of tank skin and outside surface construction do not have on a solid wall member
Cavity is disposed there between without centre.
The tank skin of usual tank includes a roof, and with bottom wall be connected roof by a bottom wall relative with the roof and one
Side wall.Then the tank skin section for setting with being mutually inclined can be made up of roof, bottom wall and side wall.Thus functional part can also
Be arranged on the wall of side and not only can preferably make full use of on roof or/and bottom wall, in this way tank skin can
For the area for using.
One be used to conveying-be particularly from the outlet of tank outflow-conveying device of working solution is used as One function
Part is advantageously disposed on tank skin.In order to not reduce the tank volume for being available for the working solution being located in tank to use, preferably conveying is filled
Put on the lateral surface for being arranged on tank skin.Conveying device is used to discharge work with a suction side for being used to suck working solution and one
Make liquid on the pressure side.
Conveying device for example can be a gear pump, a membrane pump or a peristaltic pump, wherein in selection conveying dress
The type aspect put can be arbitrarily arranged on tank skin not or be only existed the limitation of very little due to it.
In addition it is beneficial that：In order to remove impurity, a filter conduct for being used for filtration liquid from working solution
Functional part is arranged on tank skin.It is preferred that filter is arranged on the medial surface of tank skin so that it is needed filtering from four sides
Liquid wash away, this makes it possible that working solution particularly simply is conveyed into filter.
Working solution preferred embodiment is conveyed into conveying device, i.e. filter in the following way according to one to lead to
Cross what is extended in tank inner chamber, the first pipeline for guiding working solution is connected with conveying device.First pipeline has more adjunction
The injection end of nearly filter and the outlet side for being more nearly conveying device, wherein the first pipeline is filled with its outlet side with conveying
The suction side connection put.Conveying device receives the working solution by purification in this way, therefore conveying device is protected
Prevent due to the infringement that the impurity of working solution is caused.If for example conveying device or one other make jointly with the first pipeline
Functional part is arranged on the lateral surface of tank skin, and the first pipeline can draw from tank and tank can be passed through for this
Wall.
First pipeline has a duct wall as the following second pipe that should be noted that, the duct wall is in tank inner chamber
One piping volume (Leitungsvolumen) is surrounded and is separated with remaining tank internal capacity.First and second pipelines can
It is being grouped into by multi-section or entirety to be configured to.Additionally, the first and second pipelines can include flexible section, it is such as soft
Pipe, or/and rigid section, the pipe joint on such as tank skin.In order to assembly costs are kept as into very little, pipe joint valuably with
Tank skin construction is integral.
Then working solution is preferably transported to the outlet of tank from conveying device in the following way, i.e. conveying device passes through
Drawn from tank, for guiding the second pipe of working solution to be connected with the outlet of tank.Second pipe has a more adjunction
The injection end and an outlet side for the outlet for being more nearly tank of nearly conveying device, wherein second pipe is at least in its discharge
Drawn from tank at end-and be this for example through tank skin-and being on the pressure side connected using its injection end and conveying device.It is logical
Cross is used to that outlet will to be transported to from tank by the working solution of purification this way provides one, is closed with respect to tank inner chamber
Flow path, the flow path prevents the pollution of the working solution to passing through filtering.One is used to detect and conveying device
The second pipe on the pressure side connecting in the pressure sensor of pressure of working solution can be arranged on second pipe.It is preferred that this
Individual pressure sensor is arranged on tank skin and is thus arranged in a section drawn from tank of second pipe.
If conveying device is arranged on the lateral surface of tank skin, second pipe can also be at its injection end from tank
Middle extraction, that is to say, that for example through tank skin.This point is for example when in order to set the pipeline that working solution is deflected from from conveying device
Put on a conveyor and there is no sufficient structure space in a region with conveying device border of the external environment condition of tank
When can be beneficial.This measure when conveying device suction side with it is on the pressure side close to each other, be more particularly set on conveying fill
Equally can be beneficial when on the same side put.Therefore the in the case of the conveying device on the lateral surface of tank skin is arranged on
One pipeline and second pipe draw odd-times, at least three times from tank altogether.
The outlet of tank can be arranged on an arbitrary position of tank skin.Therefore outlet can not be arranged on tank
In the measurement of wall at deepest point.But it is preferred that the injection end of the first pipeline is with therefore preferably filter is arranged on the measurement of tank skin
At upper deepest point so that the injection end or filter (in the case of the tank being at least partially filled with) of the first pipeline are all the time
Obtain the supply of working solution.
If the structure that filter has labyrinth-like, it is possible to reduce working solution rock with it is resulting
Whine noise.Even if further, since the pressure of the labyrinth effect working solution integrated can also keep permanent in the case where liquid level is low
It is fixed constant.
It is preferred that tank skin is made using casting die.Casting die be it is a kind of can be in the method for especially many-sided application, the method
So that the shape of the tank structure space regulation different from motor vehicle matches.
The wall ratio of the tank skin that can be provided in the case of a tank manufactured using casting die is blow molded legal system in utilization
It is thin in the case of the tank made.The wall thickness of tank skin is valuably between 3mm and 3.5mm.In this way can with material-saving and
Reduce weight and therefore reduces cost.
Tank skin can preferably be made up of at least two ladle bowls of two definite ladle bowls, need to be arranged in this way
The assembling of the functional part on tank skin is simplified compared with integral tank is manufactured due to the accessibility for improving.For tank
Simplification maintaining the reason for, preferably multiple functional parts are arranged on a unique ladle bowl.Multiple functional parts
It is advantageously disposed on (for for installation site of the tank in the motor vehicle of horizontal positioned) bottom ladle bowl.
Additionally, by using casting die manufacture tank one or more can be set to the entirety stretched out in tank inner chamber for the tank
Anti-shake wall, thus can omit afterwards assembling anti-shake wall.Anti-shake wall is used to reduce working solution rocking in tank and thus produces
Raw whine noise.
Can also select to provide a kind of by the appropriate material for tank in the case of the tank for utilizing casting die to manufacture
Optimization of material and Weight-optimised, the supporting member for tank replaces being used in the prior art the metal supporting member of tank.
