Fuel storage assembly for a motor vehicle
A fuel storage assembly for a motor vehicle has four fuel tanks arranged to form each a corner of a substantially square cross-section of a tank array, a spacer arrangement keeps said fuel tanks apart, said spacer arrangement comprising at least one side bracket disposed along one of the vertical peripheral sides of the tank array, the at least one side bracket being arranged to be fixed to a vehicle chassis, and at least one central bracket disposed between the fuel tanks in the center of the tank array, at least one tensioning strap disposed around the fuel tanks to be secured at one first end to a top part of the at least one side bracket and at one second end to a bottom part of the at least one side bracket, the at least one tensioning strap pressing the fuel tanks together in the tank array, a protecting element to cover one or more of the horizontal and vertical peripheral sides of the tank array. The protecting element is detachably fixed to the at least one tensioning strap.
1 . A fuel storage assembly for a motor vehicle comprising:
four fuel tanks arranged to form each a corner of a substantially square cross-section of a tank array, the tank array being defined by two horizontal peripheral sides, respectively a top side and a bottom side, and two vertical peripheral sides, respectively a left side and a right side,
a spacer arrangement configured to keep the fuel tanks apart, the spacer arrangement comprising at least one side bracket disposed along one of the vertical peripheral sides of the tank array, the at least one side bracket being arranged to be fixed to a vehicle chassis, and at least one central bracket disposed between the fuel tanks in the center of the tank array,
at least one tensioning strap disposed around the fuel tanks and configured to be secured at one first end to a top part of the at least one side bracket and at one second end to a bottom part of the at least one side bracket, the at least one tensioning strap pressing the fuel tanks together in the tank array, wherein the at least one tensioning strap comprises fastening recesses configured to receive linking elements,
a protecting element configured to cover at least partially one or more of the horizontal and vertical peripheral sides of the tank array, the protecting element being detachably fixed directly to the at least one tensioning strap by the linking elements such that removal of the protecting element does not alter a compressive preload applied by the tensioning strap to the fuel tanks,
the at least one tensioning strap is made of metal, a side thereof facing the fuel tanks is covered by a high friction material.
2 . The fuel storage assembly of claim 1 , wherein the protecting element is detachably fixed to the at least one tensioning strap through at least two linking elements, respectively a first linking element disposed at the bottom or top side of the tank array and a second linking element disposed at the left or right side of the tank array.
3 . The fuel storage assembly of claim 2 , wherein each linking element is a bolt adapted to pass through a corresponding through-hole formed in the protecting element and cooperate with a corresponding nut provided in the at least one tensioning strap.
4 . The fuel storage assembly of claim 1 , wherein the at least one tensioning strap extends between a first looped end and a second looped end, the first looped end enclosing a first pin, onto which is screwed a threaded connecting element at a first end thereof, a second end thereof being screwed to a second pin, which fits into bores in a U-shaped portion of the at least one side bracket.
5 . The fuel storage assembly of claim 4 , wherein the second looped end encloses a pin, which fits into bores in a U-shaped portion of the at least one side bracket.
6 . The fuel storage assembly of claim 1 , wherein the at least one side bracket comprises two support surfaces, each of which is adapted to lie against an outer surface of a fuel tank.
7 . The fuel storage assembly of claim 6 , wherein the at least one side bracket has a central portion positioned between an upper portion and a lower portion of the at least one side bracket, the upper and lower portions each including a support surface, the central portion having a greater dimension along a lateral direction than the upper and lower portions.
8 . The fuel storage assembly of claim 7 , wherein each support surface of the at least one side bracket and/or of the at least one central bracket has a circular arc shape.
9 . The fuel storage assembly of claim 7 , wherein each support surface of the at least one side bracket and/or of the at least one central bracket is covered at least partially by a band-shaped panel adapted to prevent the fuel tanks from slipping.
10 . The fuel storage assembly of claim 9 , wherein the band-shaped panel is formed in a high friction material.
11 . The fuel storage assembly of claim 10 , wherein the high friction material is a rubber material.
12 . The fuel storage assembly of claim 1 , wherein the at least one central bracket comprises four support surfaces, each of which is adapted to lie against an outer surface of a fuel tank.
13 . The fuel storage assembly of claim 12 , wherein the at least one central bracket has a X-shaped profile defined by four vertices, two adjacent vertices being linked by a support surface.
14 . A vehicle comprising a fuel storage assembly according to claim 1 .
15 . The vehicle of claim 14 , wherein the vehicle is a truck.
