Abstract
A tank system includes an extraction device and a tank. The extraction device has an extraction line and an attachment device. The tank includes a tank top side having a fastening wall and a first tank top side section. The fastening wall and the first tank top side section delimit a tank interior space at the top side. The tank interior space can be filled with an exhaust-gas after-treatment liquid, the fastening wall is disposed obliquely to the first tank top side section, the fastening wall has a fastening surface and a tank opening, the attachment device is fastened to the fastening surface, and the extraction line is guided through the tank opening. A vehicle having the tank system is also provided.
Claims19
A tank system for a vehicle, the tank system comprising:
- a tank including a tank top side having a fastening wall and a first tank top side section, said fastening wall and said first tank top side section delimiting a top side of a tank interior space to be filled with an exhaust-gas aftertreatment liquid;
- said fastening wall being disposed obliquely relative to said first tank top side section and said fastening wall having a fastening surface and a tank opening;
- said tank including a tank base having a first tank base section and a second tank base section connected to said first tank base section, said second tank base section being disposed at a lower level than said first tank base section, said first tank base section being disposed obliquely relative to said second tank base section, and said second tank base section being disposed parallel to said first tank top side section;
- said fastening wall being disposed at least partly above said first tank base section;
- and
- an extraction device including an extraction line led through said tank opening and an attachment device fastened to said fastening surface, at least sections of said extraction line being disposed obliquely relative to said second tank base section, said extraction line extending below a majority of the first tank base section and above said second tank base section of said tank base and said extraction line being coupled to said attachment device, said extraction device being completely removable from said tank for maintenance by removing said attachment device and removing said extraction line through said tank opening.
