In the figures, the same elements or elements having the same function are indicated by the same reference signs.
Figs. 1 to 3 show a first embodiment of a tank device 10 for a vehicle, in particular a commercial vehicle such as a truck. As described in further detail below, the tank device 10 is used for receiving both a fuel for an internal combustion engine of the vehicle and a reducing agent for after treatment of exhaust gas of the internal combustion engine. This means, the vehicle, in its completely assembled state, comprises said internal combustion engine by which the vehicle can be driven. For example, said fuel is a liquid fuel such as diesel such that, for example, the internal combustion engine which is also referred to as an engine can be a diesel engine. During a fired operation of the internal combustion engine the fuel is introduced into at least one combustion chamber of the engine. Moreover, air is introduced into the combustion chamber so that a mixture is formed in the combustion engine, the mixture comprising the fuel and the air which are introduced into the combustion engine. Said mixture is burned in the combustion engine so that exhaust gas of the combustion engine is produced. The exhaust gas can flow out of the combustion chamber and through an exhaust system which, for example, comprises at least one SCR catalytic converter. Said reducing agent can be introduced into the exhaust system and, in particular, into the exhaust gas flowing through the exhaust system. In the SCR catalytic converter nitrogen oxides contained in the exhaust gas can be transformed into water and nitrogen by using the reducing agent introduced into the exhaust gas. For this purpose, for example, the reducing agent provides and/or comprises ammonium. Preferably, the reducing agent is a liquid. For example, the reducing agent can be a urea solution. Since the internal combustion engine can be a diesel engine, the exhaust gas can be a diesel exhaust gas. In this regard, the reducing agent can also be referred to as a diesel exhaust fluid (DEF).
The tank device 10 comprises a fuel tank 12 having a first end wall 14 and a second end wall. The second end wall can be seen in Figs. 4 to 6 and is designated by 58. In an embodiment, the fuel tank 12 may comprise a cylindrical cross section. In another embodiment, the fuel tank may comprise a rectangular cross section. Moreover, the fuel tank 12 comprises a peripheral shell 16 which, for example, can be formed in one piece. In an embodiment, the peripheral shell 16 is of the same shape as the fuel tank. In another embodiment, the end walls 14 can be formed separately from the shell 16, wherein the shell 16 can be connected with the end walls 14 and 58. The end walls 14 and 58 and the shell 16 bound at least one first receiving chamber in which the fuel can be or is received. Furthermore, at least a portion 18 of the shell 16 extends beyond the second end wall 58, wherein a position of the second end wall 58 is indicated in Figs. 1 to 3 by 20. As can be seen from Figs. 1 to 3, the portion 18 bounds a receiving area 22.
The tank device 10 further comprises at least one reducing agent tank 24 which is formed separately from the fuel tank 12. The reducing agent tank 24 bounds at least one second receiving chamber in which the reducing agent can be or is received. Moreover, the reducing agent tank 24 is at least partially received or accommodated in the receiving area 22, wherein the reducing agent tank 24 is supported on the portion 18 of the shell 16. As can be seen from Figs. 1 to 3, at least a major portion of the reducing agent tank 24 is arranged or accommodated in the receiving area 22. In Fig. 1, the vertical direction of the vehicle is indicated by an arrow 26. Preferably, the reducing agent tank 24 is supported on the portion 18 in the vertical direction of the vehicle downwards. In the first embodiment shown in Figs. 1 to 3, the portion 18 overlaps the reducing agent tank 24 in the vertical direction of the vehicle downwards at least partially, in particular at least predominantly. Moreover, the reducing agent tank 24 is, in the transverse direction of the vehicle, overlapped on both sides by the portion 18 at least partially.
In order to integrate the reducing agent tank 24 into the tank device 10 in a particularly cost and weight-efficient way, the tank device 10 comprises at least one securing element 28 which is formed separately from both the fuel tank 12 and the reducing agent tank 24. The securing element 28 is, on both of its ends, mounted to the portion 18, in particular to an end 30 of the shell 16. Moreover, the securing element 28 is arranged at least partially in a corresponding receptacle 32 of the reducing agent tank 24 such that the reducing agent tank 24 is secured against rotational movements in relation to the fuel tank 12 by the securing element 28. Moreover, the securing element 28 secures the reducing agent tank 24 against translational movements in relation to the fuel tank 12 along a longitudinal direction of the fuel tank 12, wherein said longitudinal direction of the fuel tank 12 is indicated by an arrow 34 and coincides with a longitudinal extension or a direction of longitudinal extension of the fuel tank 12. In the completely assembled state of the vehicle, the longitudinal direction of the fuel tank 12 coincides with the longitudinal direction of the vehicle alone.
For example, the shell 16 has a first end 36 and the end 30 being a second end of the shell 16. The end 30 of the shell 16 is also an end or the end of the portion 18. The ends 30 and 36 are spaced apart from each other in the longitudinal direction of the fuel tank 12. For example, at the first end 36 of the shell 16, the shell 16 comprises an outer end 38 of the first end wall 14 of the fuel tank 12. The second end wall 58 of the fuel tank 12 is located inwardly relative to the second end 30 of the shell 16 at some distance from the first end wall 14 of the fuel tank 12. The shell 16 contains at least one inlet 40 by which the fuel can be introduced into the first receiving chamber. Moreover, the shell 16 contains a fuel supply outlet for the fuel tank 12. The shell 16 extends beyond the second end wall 58 and is open at its second end 30. The extending portion 18 contains a through opening 42 through which the reducing agent tank 24 can be moved so as to arrange the reducing agent tank 24 at least partially, in particular at least predominantly, in the receiving area 22. For example, the through opening 42 is a trapezoidal cut-out which is generally upwardly facing in the vertical direction of the vehicle upwards. In another example, the through opening 42 is a rectangular cut-out which is generally upwardly facing in the vertical direction of the vehicle upwards. In yet another example, the through opening 42 is a semi-circular cut-out which is generally upwardly facing in the vertical direction of the vehicle upwards. It should be appreciated that alternative shapes may be used for the through opening 42 outside of the examples disclosed to achieve cut-out which is generally upwardly facing in the vertical direction of the vehicle upwards.
The shell 16 may support the reducing agent tank 24, wherein, for example, the fuel tank 12 is a first tank and the reducing agent tank 24 is a second tank. The shell 16 may support the second tank from below at the portion 18 that extends beyond the second end wall 58 of the fuel tank 12. For example, the second tank may hold diesel exhaust fluid which can also be referred to as DEF so that the second tank can also be referred to as a DEF tank. The DEF tank may contain any fluid used for exhaust gas treatment, such as a urea solution. For example, the DEF tank has a portion 44 that projects beyond the second end 30 of the shell 16. As can be seen from Fig. 2, the receptacle 32 may be a groove. In one embodiment, the receptacle 32 may be arranged on an end E of the reducing agent tank 24. Thus, for example, the DEF tank may contain the groove on the end E where the securing element 28 may be placed. As can be seen from Figs. 1 to 3, the securing element 28 may be a strap or a retainer. The securing element 28 can be mounted to the second end 30 of the shell 16 in order to fasten the DEF tank at its projected portion 44 to the extended portion 18 of the shell 16. The receptacle 32 and the securing element 28 may prevent rotation of the DEF tank relative to the field tank 12.
In the first embodiment, the receptacle 32, is arranged on an end face 46 of the reducing agent tank 24, the end face 46 facing away from the first and second end walls 14 and 58. Moreover, the extended portion 18 encompasses at least a major portion of the reducing agent tank 24 along the circumferential direction of the reducing agent tank 24, the circumferential direction of the reducing agent tank 24 being illustrated in Fig. 2 by an arrow 48. Moreover, the reducing agent tank 24 extends beyond the end 30 of the portion 18 away from the second end wall 58.
In an embodiment, the shell 16, in particular its outer body, may be continuous and/or streamlined. In another embodiment, the second end 30 of the shell 16 that extends beyond the second end wall 58 of the fuel tank 12 may extend to the end E of the DEF tank that is secured by the securing element 28.
In an alternative embodiment, the shell 16 may contain two portions, a first portion and a second portion. The first portion of the shell 16 may be located from about the first end 36 of the fuel tank 12 to about the second end wall 58 of the fuel tank 12. The second portion may be located from above the second end wall 58 of the fuel tank 12 to the second end 30 of the shell 16 that extends beyond the second end wall of the fuel tank 12. In another embodiment, the second portion of the shell 16 may be attached to the first portion of the shell 16 by a method such as welding. In another embodiment, the DEF tank has a portion that projects beyond the opening 32 of the second portion of the shell 16. In an alternative embodiment, the second portion of the shell 16 may extend to the end E of the DEF tank that is secured by the securing element 28.
Figs. 4 to 6 show a second embodiment of the tank device 10. In the second embodiment, the tank device 10 comprises straps 50, which are, for example, configured as channel straps. The straps 50 are formed separately from the fuel tank 12 and the reducing agent tank 24. The straps 50 are attached to the end 30 of the fuel tank 12 respectively. Moreover, the straps 50 are formed separately from each other. Moreover, the tank device 10 according to the second embodiment comprises at least one fastening element 52 which can be configured as a cross brace having cross brace legs 54. The fastening element 52 is formed separately from the reducing agent tank 24, the fuel tank 12 and the straps 50. Moreover, the fastening element 52 is attached to the strap 50 and arranged at least partially in a receptacle 56 of the reducing agent tank 24, so that the reducing agent tank 24 is fastened to the fuel tank 12 by the fastening element 52 and the straps 50. For example, the straps 50 are attached at the end 30 of the fuel tank 12. Each channel strap may be provided with a first end and a second end. The channel straps may be attached to the end 30 of the fuel tank 12 through weldments at the respective first ends. The second end of the respective channel strap may extend beyond the end 30 of the fuel tank 12 for which the respective channel strap is mounted at some distance. The DEF tank may also be provided that contains a cross brace groove on the end E. This means the receptacle 56 can be a groove or a cross brace groove in which the fastening element 52 can be arranged at least partially. The cross brace groove may contain the respective cross brace leg 54 that may be attached, such as through bolts, to each second end of the channel straps in order to secure the DEF tank in place relative to the field tank 12. The cross brace groove may prevent rotation of the DEF tank relative to the fuel tank 12.
In a further embodiment, the second portion of the shell 16 can be connected to the first portion of the shell 16 and/or to the second end wall of the fuel tank 12. For example, the second end wall 58 is an end cap of the fuel tank 12. For example, the first portion of the shell 16 is welded to the second portion of the shell 16 and/or the end cap of the fuel tank 12. Thus, for example, the portion 18 is formed at least partially, in particular at least predominantly or completely, by the second portion of the shell 16 so that the portion 18 or the second portion of the shell 16 may function as a shield or cage supporting the DEF tank. The securing element 28 or the fastening element 52 respectively lies inside the respective groove and is fastened to the portion 18 or the shell 16 respectively. The securing element 28 or the fastening element 52 respectively acts as an anti-rotation feature securing the DEF tank from rotating relative to the fuel tank 12.
