Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0028] The present application provides a vehicle gas system, including a cab suspension and a gas cylinder bracket fixed to a frame 1, the cab suspension including a proximal suspension 2 and a distal suspension 3 spaced apart along the axial direction of the frame 1 to accommodate cabs of different specifications; the gas cylinder bracket includes a first bracket 4 and a second bracket 5 respectively arranged on both sides of the frame 1, and the length of the first bracket 4 is greater than that of the second bracket 5, the first bracket 4 and the second bracket 5 are respectively installed with a first gas cylinder 6 and a second gas cylinder 7, one of the first gas cylinder 6 and the second gas cylinder 7 is connected to a gas filling port 8, and the other is connected to a filter 9.

[0029] By means of the interspaced arrangement of the proximal mount 2 and the distal mount 3 in this solution, the installation of different cabs can be adapted, and the vehicle's gas system does not need to be rearranged and adjusted according to the cab specifications, so that the vehicle's gas system can be directly arranged on the frame 1 of different models, thereby achieving its versatility.

[0030] Preferably, the first gas cylinder 6 is connected to the filter 9 , and the second gas cylinder 7 is connected to the gas filling port 8 .

[0031] Furthermore, the vehicle frame 1 is provided with a fender 12 , the proximal suspension 2 and the distal suspension 3 are respectively located at the front and rear sides of the fender 12 , and the filter 9 is located between the fender 12 and the distal suspension 3 .

[0032] Furthermore, the gas system includes a pressure reducing regulator 10 connected to the filter 9. The pressure reducing regulator 10 is located between the near mount 2 and the far mount 3 and above the fender 12. The pressure reducing regulator 10 is arranged in a space-saving manner without affecting the layout of the vehicle cargo box.

[0033] In one embodiment, the gas system further includes a pressure gauge, and the gas filling port 8 and the pressure gauge are fixed to the second bracket 5. The gas filling port 8 and the pressure gauge are fixed to the second bracket 5, and the second gas cylinder 7 is connected at the second bracket 5, with a short connection path and a compact structure.

[0034] Furthermore, the vehicle gas system includes a vent line 11 connecting the first gas cylinder 6 and the second gas cylinder 7. The vehicle frame 1 is provided with a through hole for the vent line 11 to pass through. The vent line 11 connects the first gas cylinder 6 and the second gas cylinder 7. When the gas is filled through the gas filling port 8, the vent line 11 can be used to introduce gas into the first gas cylinder 6, thereby achieving the goal of providing the gas filling port 8 on a single side to charge the gas cylinders on both sides.

[0035] Preferably, the frame 1 is provided with a crossbeam 110, and the ventilation pipe 11 is at least partially fixed to the crossbeam 110. This method realizes the limitation of the ventilation pipe 11, which is beneficial to prevent the ventilation pipe 11 from being entangled or scattered and bumped.

[0036] In one embodiment, a clearance is provided between the first bracket 4 and the second bracket 5 and the corresponding rear wheels of the vehicle, so as to reserve space for the arrangement of other vehicle components and prevent the gas cylinder from being bumped during driving.

[0037] The vehicle gas system in this solution features two brackets on either side of the vehicle frame 1 for securing two gas cylinders. A gas inlet 8 is located on only one side, and a filter 9 is located on the other. The two cylinders are ventilated via a connecting pipeline, eliminating the need for separate gas inlets 8 and filters 9 for each cylinder. This reduces component requirements and allows for more efficient use of the space available for the cylinders. The connecting pipeline is routed and secured through the vehicle frame 1 during layout, effectively utilizing the structure and space, avoiding cluttered routing, and ensuring connectivity between the two cylinders.

[0038] Natural gas is introduced into the second gas cylinder 7 through the gas filling port 8. Since the second gas cylinder 7 is connected to the first gas cylinder 6 through the ventilation pipe 11, the gas is filled into the first gas cylinder 6 along the ventilation pipe 11. After the gas in the first gas cylinder 6 is filled, the gas is filled into the second gas cylinder 7. The pressure in the two connected first gas cylinders 6 and second gas cylinders 7 is judged by a pressure gauge. When the pressure reaches a preset value, ventilation is stopped.

[0039] When driving, gas is supplied to the engine 13 through the first gas cylinder 6. The pressure reducing regulator 10 and the filter 9 are located on the side of the frame 1 where the first gas cylinder 6 is set. The volume of the first gas cylinder 6 is large, so it is more reasonable to supply gas directly from the first gas cylinder 6. Similarly, since the first gas cylinder 6 is connected to the second gas cylinder 7 through the ventilation pipe 11, the filter 9 and the pressure reducing regulator 10 are only set on one side, so that the gas in the two gas cylinders can be utilized.

[0040] The overall structure of this solution is compact, and it can provide more space for placing gas cylinders on both sides of the frame 1 to increase the capacity of the gas cylinders, which is beneficial to improving the vehicle's cruising range.

[0041] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0042] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0043] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
