Description

TANK DEVICE FOR A VEHICLE, IN PARTICULAR A COMMERCIAL VEHICLE
FIELD OF THE INVENTION
[0001] The invention relates to a tank device for vehicle, in particular a commercial vehicle.
BACKGROUND INFORMATION
[0002] US 6 223 526 B1 shows a structural unit for holding fuel for an internal combustion engine having an exhaust gas purification system using a reducing agent, wherein said structural unit comprises a fuel space for holding the fuel. The structural unit further comprises a reducing agent space for holding the reducing agent separate from the fuel. Furthermore, US 2011/0036847 Al shows an apparatus for separately containing different fluids, comprising a first vessel having a perimeter wall and at least one end wall defining an internal space, a portion of the perimeter wall extending beyond the at least one end wall to form a rim defining with the at least one end wall a recess. The apparatus further comprises a second vessel having a shape conforming to the recess, wherein the second vessel is supported in the recess. Moreover, US 2013/0292386 Al shows a DEF and fuel fill system.
SUMMARY OF THE INVENTION
[0003] It is an object of the present invention to provide a tank device for a vehicle such that both a fuel and a reducing agent may be received in a particularly cost-effective way.
[0004] This object is solved by a tank device having the features of patent claim 1. Advantageous embodiments with expedient developments of the invention are indicated in the other patent claims.
[0005] The invention relates to a tank device for a vehicle, in particular a commercial vehicle. The tank device comprises a reducing agent tank for receiving a reducing agent. For example, the reducing agent is a liquid. Preferably, the reducing agent is an aqueous urea solution. The tank device further comprises a fuel tank for receiving a fuel, in particular a liquid fuel. The fuel tank comprises a shell with a first end and a second end. The fuel tank further comprises a first end wall which is arranged at and connected with the first end of the shell. The fuel tank further comprises a second end wall which is spaced away from the first end wall in a longitudinal direction of the fuel tank. Moreover, the second end wall is connected with the shell. Preferably, the shell and the end walls are configured as separately manufactured components which are connected with each other. For example, the reducing agent tank comprises a first receiving space for receiving the reducing agent. Moreover, for example, the fuel tank comprises a second receiving space for receiving the fuel. For example, the second receiving space is bound by the shell and the end walls. For example, the second receiving space, in particular at both of its ends, is bound by the end walls in the longitudinal direction of the fuel tank. Moreover, for example, the shell surrounds the second receiving space in a circumferential direction of the fuel tank, the circumferential direction of the fuel tank extending around the longitudinal direction of the fuel tank. For example, the shell bounds the second receiving space in the circumferential direction of the tank.
[0006] In the tank device according to the present invention, the shell extends beyond the second end wall to the second end of the shell along the longitudinal direction of the fuel tank such that the shell comprises a length portion which is also referred to as an extending portion or an extended portion. The length portion of the shell extends, along the longitudinal direction of the fuel tank, from the second end wall to the second end of the shell thereby forming a receptacle in which the reducing agent tank is arranged. The receptacle, per se, is open at the second end of the shell along the longitudinal direction of the fuel tank. Thus, for example, the receptacle, when viewed alone, is open (i.e. not limited) in a first direction running along the longitudinal direction of the fuel tank and facing away from the second end wall. Furthermore, the receptacle, per se, is limited by the second end wall along the longitudinal direction of the fuel tank. This means that the receptacle, when viewed alone, is limited by the second end wall in a second direction running along the longitudinal direction of the fuel tank, wherein the second direction is opposite of the first direction. Thus, the second direction runs away from the second end of the shell.
[0007] The length portion of the shell extends in the circumferential direction of the fuel tank over a first angular region around the receptacle and the reducing agent tank in such a way that the length portion comprises two ends which are spaced away from each other in the circumferential direction of the fuel tank. Thereby, the ends of the length portion bound, in the circumferential direction of the fuel tank, a through opening which is arranged between the two ends of the length portion along the circumferential direction of the fuel tank. Thus, the through opening extends, in the circumferential direction of the fuel tank, over a second angular region around the receptacle and the reducing agent tank, wherein the second angular region abuts the first angular region, in particular directly. Thereby, the through opening overlaps a major first portion (i.e. more than the half) of a width of the reducing agent tank whose width extends in a transverse direction of the fuel tank. The transverse direction of the fuel tank extends perpendicularly to the longitudinal direction of the tank. Preferably, the second angular region is smaller than the first angular region. For example, the trough opening may be configured as a cut out of the length portion or the shell. Moreover, preferably, the through opening may face at least substantially upwards, in particular in a vertical direction of the fuel tank. For example, with respect to a completely manufactured state of the vehicle, the transverse direction of the fuel tanks coincides with or extends parallel to a transverse direction of the vehicle. Moreover, for example, with respect to the completely manufactured state of the vehicle, the longitudinal direction of the fuel tank coincides with or extends parallel to a longitudinal direction of the vehicle which, when driven forwards in a straight line, travels along its longitudinal direction. Thus, for example, with respect to the completely manufactured state of the vehicle, the vertical direction of the fuel tank coincides with or extends parallel to a vertical direction of the vehicle. In this regard, the vehicle is equipped with the tank device in said completely manufactured stat of the vehicle. For example, in the completely manufactured state of the vehicle, the tank device is attached to a frame of the vehicle, wherein, for example, the frame may be configured as a ladder frame.
[0008] A second portion of the width of the reducing agent tank is overlapped by a part of the length portion such that, for example, the second portion of the width is overlapped by said part of the length portion upwards in the vertical direction of the fuel tank and thus the vehicle. In this regard, the second portion abuts the first portion, in particular directly.
[0009] The invention may resolve space and packaging constraints thereby allowing to achieve an efficient packaging solution. Moreover, in comparison with conventional solutions, the invention may result in cost reduction since separate and additional mounting brackets for mounting the reducing agent tank may be avoided. Thereby, the weight of the tank device may be kept particularly low. Moreover, the invention may free up frame rail space for other components and result in better and efficient packaging.

The features and feature combinations previously mentioned in the description as well as the features and feature combinations mentioned in the following description of the figures and/or shown in the figures alone may be employed not only in the respectively indicated combination but also in any other combination or taken alone without leaving the scope of the invention.

The following description is, therefore, not to be taken in a limiting sense.
[0020] Fig. 1 shows, in a schematic side view, a tank device 10 for a vehicle, in particular a commercial vehicle. This means that, in a completely manufactured state of the vehicle, the vehicle is equipped with the tank device 10. The vehicle may comprise a frame which may be configured as a ladder frame. For example, the tank device 10 may be attached to the ladder frame. The tank device 10 comprises a reducing agent tank 12 for receiving a reducing agent. The reducing agent may be introduced into an exhaust gas of an internal combustion engine of the vehicle which may be driven by the internal combustion engine. The reducing agent may be used to remove nitrogen oxides from the exhaust gas. For example, the reducing agent may be configured as a diesel exhaust fluid (DEF), in particular if the internal combustion engine is a diesel engine. Preferably the reducing agent tank 12 comprises or bounds a first receiving space for receiving the reducing agent. Preferably the reducing agent is a liquid such as, for example, an aqueous urea solution. In an embodiment, the tank device 10 may comprise a rectangular-type contour.
[0021] The tank device 10 further comprises a fuel tank 14 for receiving a fuel, in particular a liquid fuel. Preferably, said engine may be operated by said fuel. For example, the fuel tank 14 may comprise or bound a second receiving space in which the fuel may be received. The fuel tank 14 comprises a shell 16 with a first end El and a second end E2, wherein the ends El and E2 are opposite each other in a longitudinal direction of the fuel tank 14. The longitudinal direction of the fuel tank 14 is illustrated by a double arrow 18. The fuel tank 14 further comprises a first end wall 20 arranged at the first end El. The end wall 20 is connected with the first end El and thus the shell 16.
[0022] The fuel tank 14 further comprises a second end wall 22 which is spaced away from the first end wall 20 in the longitudinal direction of the fuel tank 14. The second end wall 22 is also connected with the shell 16. The second receiving space, at both of its ends, is limited by the end walls 20 and 22 in the longitudinal direction of the fuel tank 14. Moreover, the shell 16, in particular a peripheral shell portion 24 of the shell 16, surrounds, in a circumferential direction of the fuel tank 14, the second receiving space, in particular completely. Said circumferential direction of the fuel tank 14 extends around the longitudinal direction of the fuel tank 14. The peripheral shell portion 24 extends from the end wall 20 to the end wall 22 in the longitudinal direction of the fuel tank 14 or vice versa. In an embodiment, the fuel tank 14 may comprise a rectangular-type contour.
[0023] The shell 16 extends beyond the second end wall 22 to the second end E2 of the shell 16 along the longitudinal direction of the fuel tank 14 such that the shell 16 also comprises a length portion L which is also referred to as an extended portion. The length portion L extends, along the longitudinal direction of the fuel tank 14, from the second end wall 22 to the second end E2 of the shell 16 thereby forming a receptacle 26 in which the reducing agent tank 12 is arranged. The receptacle 26, per se, is open at the second end E2 of the shell 16 along the longitudinal direction of the fuel tank 14. This means that the receptacle 26, when viewed alone, is open in a first direction which runs in the longitudinal direction of the fuel tank 14 and points away from the end wall 22. The first direction is illustrated by an arrow 28. The receptacle 26, per se, is limited by the second end wall 22 along the longitudinal direction of the fuel tank 14. This means that the receptacle 26, when viewed alone, is limited by the second end wall 22 in a second direction which runs in the longitudinal direction of the fuel tank 14 and points away from the end E2 and towards the end wall 22. Said second direction is opposite of said first direction.
Moreover, the second direction is illustrated by an arrow 30. Furthermore, the length portion [extends in the circumferential direction of the fuel tank 14 over a first angular region around the receptacle 26 and the reducing agent tank 12 in such a way that the length portion [comprises two ends 32 and 34 (Fig. 3) which are spaced away from each other in the circumferential direction of the fuel tank 14. Thereby, the two ends 32 and 34 of the length portion [bound, in the circumferential direction of the fuel tank 14, a through opening 36 which may be formed by a cutout of the length portion L of the shell 16. The through opening 36 extends, in the circumferential direction of the fuel tank 14, over a second angular region around the receptacle 26 and the reducing agent tank 12. For example, the first angular region may be within a range of 2000 to 270°. Thus, for example, the second angular region may be within a range of 1600 to 90°.
[0024] As shown in Figs. 2 and 3, the through opening 36 extends over the second angular region around the receptacle 26 and the reducing agent tank 12 in such a way that the through opening 36 overlaps a major first portion of a width of the reducing agent tank 12, the width of the reducing agent tank 12 extending in a transverse direction of the fuel tank 14. The transverse direction of the fuel tank 14 is illustrated by a double arrow 38. The transverse direction of the fuel tank 14 extends perpendicularly to the longitudinal direction of the fuel tank 14. Moreover, a vertical direction of the fuel tank 14 is illustrated by double arrow 40, the vertical direction of the fuel tank 14 extending perpendicularly to both the longitudinal and transverse directions of the fuel tank 14. In Figs. 2 and 3, the major first portion of the width of the reducing agent tank 12 is indicated by P1. A second portion P2 of the width of the reducing agent tank 12 is overlapped by a part 42 of the length portion L, the second portion P2 directly abutting the first portion P1. In the embodiment shown in the figures, the portion P1 is overlapped by the through opening 36 upwards in the transverse direction of the fuel tank 14 such that the portion P1 is not overlapped by the length portion L in the vertical direction of the fuel tank 12 upwards. Moreover, the portion P2 is overlapped by the part 42 of the length portion [upwards in the vertical direction of the fuel tank 14. As shown in the figures, the reducing agent tank 12 arranged in the receptacle 26 is retained in the receptacle 26 along the transverse direction of the fuel tank 14 by the length portion L. Moreover, the reducing agent tank 12 is retained in the receptacle 26 along the vertical direction of the fuel tank 14 by the length portion L. In the first direction, the reducing agent tank 12 is retained in the receptacle 26 by the end wall 22. In order to retain the reducing agent tank 12 in the receptacle 26 in the first direction, at least or exactly one strap 44 is used. The strap 44 is arranged at and connected with the second end E2 of the shell 16, the strap 44 overlapping a side 46 of the reducing agent tank 12 partially thereby retaining the reducing agent tank 12 in the receptacle 26 in the first direction. Said side 46 faces away from the second end wall 22 in the longitudinal direction of the fuel tank 14, particularly in the first direction. The strap 44 engages a recess 48 of the side 46. Preferably, the reducing agent tank 12 is uniquely designed to fit into the receptacle 26. As shown in the figures, the length portion L may be a shell extension of the shell 16, the shell extension partially bounding the receptacle 26.
[0025] The fuel tank 14 has a fuel tank fill neck 50 via which said fuel may be introduced into the second receiving space. Moreover, the reducing agent tank 12 comprises a reducing agent tank fill neck 52 via which the reducing agent may be introduced into the first receiving space.
[0026] For example, the length portion L and the peripheral shell portion 24 may be formed by an integral part (i.e. by an integrally formed part). In other words, the length portion L and the peripheral shell portion 24 may be integral parts of an integrally formed component. Alternatively, the peripheral shell portion 24 and the length portion L may be configured as separately manufactured components which may be connected with each other at least indirectly or directly. For example, the length portion L may be welded on or to the end wall 22 such that the end wall 22 and the length portion L welded thereto may form a welded assembly. For example, said welded assembly may be welded on or to the peripheral shell portion 24, in particular in such a way that the end wall 22 may be welded to the peripheral shell portion 24. For example, the length portion L and/or the end wall 22 may have a continuous weld around a perimeter of the fuel tank 14. In case that a continuous fuel tank shell is used (i.e. if the length portion L and the peripheral shell portion 24 are formed by an integral part), the end wall 22 may be internally welded to the shell 16. The strap 44 is also referred to as a retainer strap which may allow for ease of serviceability of the reducing agent tank 12. For example, the retainer strap 44 may be screwed to the shell 16, in particular by at least one screw 54.
[0027] The reducing agent tank 12 may be a secondary tank which may have a rectangular-type contour. For example, the tank device 10 may be used in a medium-duty commercial vehicle. The shell 16 may contain an inlet via which the fuel may be introduced into the second receiving space. For example, the inlet may comprise the fuel tank fill neck 50. Moreover, for example, the shell 16 may comprise a fuel supply outlet.
[0028] The length portion L may support the reducing agent tank 14 from below. The secondary tank may hold a diesel exhaust fluid (DEF) such that the secondary tank may be configured as said reducing agent tank 12. The reducing agent tank 12 may contain any fluid used for exhaust gas treatment, such as a urea solution. In some embodiments, the reducing agent tank 12 may have a portion that projects beyond the opening of the second end E2 of the shell 16. The recess 48 may be a groove in which the strap 44 engages. For example, another retainer for retaining the reducing agent tank 12 in the receptacle 26 may be used. The strap 44 or retainer may be mounted to the second end E2 of the shell 16 in order to fasten the reducing agent tank 12 at its projected portion to the extended portion of the shell 16. The recess 48 may prevent rotation of the reducing agent tank 12 relative to the fuel tank 14.
[0029] In an embodiment, a body of the shell 16 may be continuous and streamlined. In another embodiment, the second end E2 of the shell 16 that extends beyond the second end wall 22 of the fuel tank 14 may extend to an end of the reducing agent tank 12 which is secured by the strap 44 or the retainer.
[0030] In alternative embodiment, the shell 16 may comprise two portions, a first portion and a second portion. For example, the first portion may be the peripheral shell portion 24, and the second portion may be the length portion L. The first portion of the shell 16 may be located from about the first end wall 20 of the fuel tank 14 to about the second end wall 22 of the fuel tank 14. The second portion of the shell 16 may be located from about the second end wall 22 of the fuel tank 14 to the second end E2 of the shell 16 that extends beyond the second end wall 22 of the fuel tank 14. 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 reducing agent tank 12 may have a portion that projects beyond the second end E2 of the shell 16. In an alternative embodiment, the second portion of the shell 16 may extend to the end of the reducing agent tank 12 that is secured by the strap 44 or the retainer.
