Abstract

A filling system on a motor vehicle, having at least two storage tanks for operating materials, comprising a tank closure cover which closes an opening in a body of the motor vehicle and is movable from a first position that closes the opening into a second position that releases the opening, wherein at least two filling openings of the storage tanks are arranged below the tank closure cover, a filler trough that forms an enclosure of the filling opening, wherein the filler trough closes the opening in the body and is fixed to the body; and at least one filler head, wherein the filling openings are formed as a part of the filler head, the filler head defining at least two mouth-hole necks which are combined to form a common component and are integrally connected to each other, each mouth-hole neck forming a filling opening for another storage tank.

First claim

What is claimed is:

1. A filling system on a motor vehicle, having at least two storage tanks for operating materials, comprising:
a tank closure cover which closes an opening in a body of the motor vehicle and is movable from a first position which closes the opening into a second position which releases the opening,
wherein at least two filling openings of the at least two storage tanks are arranged below the tank closure cover and are concealed in the first position of the tank closure cover,
a filler dish which forms a surround of the at least two filling openings,
wherein the filler dish closes the opening in the body of the motor vehicle on a vehicle side,
wherein the filler dish is fixed to the body of the motor vehicle,
a filler head,
wherein the at least two filling openings are formed as part of the filler head,
wherein the filler head defines at least two mouthpiece necks which are combined to form a common component and are integrally connected to each other, and
wherein each mouthpiece neck of the at least two mouthpiece necks forms a filling opening of the at least two filling openings for a different storage tank of the at least two storage tanks.

2. The filling system as claimed in claim 1 , wherein the filler head is injection-molded from thermoplastic material or is assembled from injection-molded components of thermoplastic material.

3. The filling system as claimed in claim 1 , wherein the filler head is formed at least partially electrically conductive, and is connected electrically conductively to the body of the vehicle.

4. The filling system as claimed in claim 1 , wherein the filler head is formed of a thermoplastic material which comprises an electrically conductive filler.

5. The filling system as claimed in claim 1 , wherein the filler head has a metal surround and/or a metal insert which is connected electrically conductively to the body of the motor vehicle.

6. The filling system as claimed in claim 1 , wherein the filler head is fixed to the body of the motor vehicle.

7. The filling system as claimed in claim 1 , wherein the filler dish is formed of a thermoplastic elastomer.

8. The filling system as claimed in claim 1 , wherein the filler head comprises at least one closure flap mechanism which seals at least one of the at least two filling openings without a filler cap.

9. The filling system as claimed in claim 8 , wherein each closure flap mechanism is connected electrically conductively to the body of the motor vehicle.

10. The filling system as claimed in claim 8 , wherein the filler head has a filling channel for fuel and each closure flap mechanism closes the filling channel for fuel.

11. The filling system as claimed in claim 8 , wherein each closure flap mechanism is lockable and unlockable electrically.

12. The filling system as claimed in claim 8 , wherein each closure flap mechanism is actuatable electrically and/or pneumatically.

13. The filling system as claimed in claim 1 , wherein the filler head has a filling channel for fuel and a filling channel for a watery additive for selective catalytic exhaust gas denitrification.

14. The filling system as claimed in claim 1 , wherein the filler head has a filling channel for fuel and a filling channel for water.
