Description

燃料箱装置
技术领域
本发明涉及一种用于汽车的燃料箱装置和一种用于制造这种燃料箱装置的方法。
背景技术
燃料驱动的汽车通常使用燃料箱，特别是汽油或柴油箱来运载所需的燃料。在这种燃料箱中，现在增加了各种配件用于增加燃料箱的功能，例如燃料输送泵，通风阀、液位传感器、防波罐、抽吸管路等。
在燃料箱中安装这种附加部件通常是麻烦的，因为它必须在小的空间内完成，例如通过安装孔，并且必须在燃料容器上设置适当的紧固件。
另外，燃料箱中少量燃料的使用是困难的，例如在车辆组装之后的第一次加油期间或者在上坡和下坡时油箱液位较低时，因为燃料分布在整个油箱中，所述油箱特别是对于卡车而言是非常大的并且具有复杂的形状。
发明内容
本发明所要解决的技术问题在于，在以下方面改进汽车的燃料箱装置，并且尤其是提供一种燃料箱装置，其能够在燃料箱中有效地使用少量的燃料，并且能够容易地制造。本发明所要解决的技术问题还在于提供一种制造这种燃料箱装置的简单方法。
所述技术问题通过一种汽车的燃料箱装置解决，该燃料箱装置包括燃料箱和加油模块，其中所述加油模块插入燃料箱中、或者附接到燃料箱上并且固定在燃料箱上，其中加油模块包括燃料存储器和加注接管，其中加注接管这样与加油模块的燃料存储器流体连通，使得加油通过加注接管仅进入燃料存储器，其中，燃料箱不具有额外的加注接管，使得向燃料箱的加油仅通过加油模块的燃料存储器进行。
根据本发明，使用了与燃料箱相比通常更小的附加的燃料存储器，其插入较大的燃料箱中或者从外部附接在燃料箱上。所述燃料存储器在装入燃料箱之前、或者说在组装之前已经配备了所需的附加部件。为了该附加的燃料存储器能够实现燃料箱中高效的余量容器的功能，则需保证，在给汽车加油因而给燃料箱加油时燃料仅仅、尤其直接地进入燃料存储器。已经在燃料箱外预制成的加油模块因此包括用于填充加油模块的燃料存储器的加注接管。
加注接管可以直接形成在燃料箱上，特别是作为燃料箱的凸缘。然后，加注接管可以穿过燃料箱的预先准备好的开口。
加注接管可以形成在加油模块的罩盖元件上，其中，罩盖元件从外部安置在燃料箱上。然后，加注接管尤其可以伸入到燃料存储器的开口中和/或燃料存储器的凸缘中。
加油模块和/或罩盖元件可以包括用于关闭加注接管的油箱盖。
加油模块、特别是加注接管或凸缘还可以包括防止燃料盗窃的防盗装置。
优选在燃料存储器上设置一个或多个连接开口和/或连接阀，使得燃料箱的填充可以经由燃料存储器的连接开口和/或连接阀进行。所述阀被设置为，当在燃料存储器中、在阀上存在燃料时，释放燃料存储器与燃料箱之间的连通端口，并且当不存在燃料时关闭连通开口。
优选地，至少一个浮子阀设置在燃料箱中但在燃料存储器外部，其设置为，使得当浮子阀被燃料包围时打开通向燃料存储器的流体连接，并且当其未被燃料包围时关闭通向燃料存储器的流体连接。
燃料存储器以及因此加油模块优选地具有至少一个抽吸管路，其中抽吸管路连通燃料箱。燃料可以从抽吸管路在燃料箱中的连通端(其也可以配备浮子阀)被吸入燃料存储器中。
加油模块优选具有用于测量油箱中的液位的液位传感器。
加油模块优选具有用于输送来自燃料存储器的燃料的燃料泵。
加油模块优选地还具有通向机动车辆的发动机的供应和回流管路。供应和回流管路尤其固定在罩盖元件上。
加油模块优选具有压力补偿阀和/或通风装置。
加油模块优选具有水分离器。
燃料箱尤其可以是卡车的主油箱，尤其是卡车的鞍形油箱的主油箱。
本发明还提供一种制造这种燃料箱装置的方法，其可以包括如下步骤：所述加油模块在插入之前被装配，其中所述装配包括或可选地不包括加注接管，然后将加油模块装入燃料箱并固定在燃料箱中。如果在燃料存储器的固定之前加注接管没有安装在燃料存储器上，则接下来将加注接管与燃料存储器流体连接。
然后燃料箱的加油仅通过加注接管进行，该加注接管同时充当燃料存储器的直接加油的加注接管，并且作为燃料箱的间接加油的加注接管。
附图说明
以下示范性地参照附图描述本发明。
图1示出按照本发明的燃料箱装置在其制造过程中的示意剖视图。
图2示出按照本发明的燃料箱装置的示意剖视图。
图3示出按照本发明的燃料箱装置的另一种实施形式的示意剖视图。
图4示出按照本发明的燃料箱装置的又一种实施形式的示意剖视图。
具体实施方式
图1示出了根据本发明的在制造过程中的燃料箱装置，其包括燃料箱1和加油模块2。加油模块2至少大部分在其插入和紧固在燃料箱1中之前被组装，并且接下来沿着图1所示的箭头的方向插入燃料箱1并且固定在燃料箱1中。燃料箱1例如具有用于插入加油模块2的安装开口，或者在插入过程中例如仅由半壳构成，只有在加油模块2已经插入之后第二半壳才被焊接，螺纹连接或粘接在所述半壳上。如图1和图2所示，在插入燃料存储器3之前，加注接管4已经形成在或连接到该燃料存储器上。在其他情况中，如图3所示，加注接管4也可以在所述插入之后与燃料存储器3相连。
图2示出了根据本发明的燃料箱装置的更多细节。其包括至少一个，优选地多个连接开口8，其形成在燃料存储器3上，即形成在朝向燃料箱1限定燃料存储器3的边界壁上，并且连接开口设置为允许燃料箱1能够通过连接开口8加油。
当通过加注接管4给燃料存储器3加油时，或者当通过回流管路11填充燃料存储器3时，并且燃料存储器3中的燃料液位达到连接开口8的水平，则燃料可以溢流进入燃料箱1。
加油模块2包括至少一个供应和回流管路11，用于将来自燃料存储器3的燃料输送到机动车辆的发动机和从机动车辆的发动机回流。为了输送燃料，加油模块2可以包括燃料泵。
回流管路11被布置成使得回流的燃料总是进入燃料存储器3。
燃料箱装置在燃料箱1中具有浮子阀13，当浮子阀13被燃料箱1中的燃料围绕时，浮子阀13打开与燃料箱3的流体连接，并且在没有燃料施加到浮子阀13上时，浮子阀13关闭所述流体连接。当浮子阀13打开时，则可以通过浮子阀13从燃油箱1中取出燃料。当浮子阀13由于在燃料箱1中没有燃料在浮子阀13处而关闭时，仅从燃料存储器3提供燃料供应。
浮动阀13可以由一个单元构成，该单元包括：在燃料存储器3外部设置在燃料箱1中的浮子阀13，与之相连的T形件，然后与该T形件相连的处于燃料存储器3中的负压阀，特别是弹簧阀。
位于弹簧阀(即负压阀)与浮子阀13之间的T形件可直接与供应管路，特别是柴油供给管路相连。
当浮子阀13关闭时，在供应管路中产生负压，并且真空阀即弹簧阀打开。然后通过燃料存储器3进行燃料供应。
当浮子阀13打开时，通过燃料箱1中的浮子阀13进行燃油供应。然后弹簧阀是关闭的。在此不通过燃料存储器3供应燃料。
燃料存储器3还可以具有多个连通燃料箱1的抽吸管路路9，使得来自燃料箱1的燃料可以被吸入到燃料存储器3中。在抽吸管路路9的自由端同样可以设置浮子阀。
加油模块2还具有用于测量燃料箱1中的液位的液位传感器10，例如曲杆传感器。
加油模块2可具有压力补偿阀和/或通风装置，加油模块2也可具有水分离器。
加油模块2包括用于关闭加注接管4的油箱盖6。加油模块2还可以包括用于燃料的防盗装置。
如图2和图3所示，燃料箱1是卡车的鞍形油箱的主油箱，所述鞍形油箱除主油箱外还具有附加油箱。
图3示出了燃料箱装置的一个实施形式，其中加油模块2的盖元件5随后被安置在加油模块2的其余部分上，特别是燃料存储器3上。
在加油模块2的罩盖元件5上形成可从外部触及的加注接管4。罩盖元件5从外部安置在燃料箱1上并且固定在其上。
加注接管4优选地插入燃料存储器3的凸缘7中，使得加注接管和燃料存储器直接导流地连接并且全部燃料直接进入燃料存储器3中。
图4的实施形式与图1至3的实施形式的不同之处在于，在此，加油模块2，尤其就是燃料存储器3附接到燃料箱1的壁上并在外侧固定在燃料箱1上。
加油模块2的固定尤其可以通过外部围绕的轨道焊接、在形成轨道接缝的情况下实现，或者例如作为粘合连接实现。
在燃料存储器3和燃料箱1之间，燃料存储器3和燃料箱1的在轨道接缝的区域内的壁共同作为金属隔壁。
