[0029] The accompanying drawings are for illustrative purposes only and are not to be construed as limitations on this patent. To better illustrate this embodiment, some components of the accompanying drawings may be omitted, enlarged, or reduced in size, and do not represent the actual dimensions of the product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted from the accompanying drawings. DETAILED DESCRIPTION
[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0031] Example 1:
[0032] like Figures 3 to 7 As shown, this embodiment provides a trailer chassis fuel tank mounting structure, including a trailer chassis frame, the trailer chassis frame including two longitudinal beams 1 located in a middle position and arranged in parallel, a fuel tank mounting position is provided between the two longitudinal beams 1, and a fuel tank 2 is fixed at the fuel tank mounting position.
[0033] Specifically, multiple sets of mounting lugs 3 can be welded to the corresponding locations on both sides of the fuel tank 2 and on the two longitudinal beams 1, depending on the size and weight of the fuel tank 2. The mounting lugs 3 are L-shaped structures formed by connecting horizontal and vertical plates. The vertical plates are fixed to the fuel tank, and the horizontal plates are located below the corresponding longitudinal beams. The horizontal plates are also provided with slotted holes for bolts to facilitate installation and adjustment.
[0034] The fuel tank is fixed to the two longitudinal beams 1 of the trailer chassis frame by bolts and mounting lugs 3. The longitudinal beam structure has high strength. When installing the fuel tank, there is no need to add other structural fixings to increase the strength. It also eliminates the need to add fuel tank fixing frames, fuel tank brackets and fuel tank fixing straps. The fuel tank installation and manufacturing structure is simple and reliable.
[0035] Since the fuel tank 2 is installed in the middle of the trailer chassis frame, refueling is inconvenient. In this embodiment, the refueling pipe 4 of the fuel tank 2 is led to the cabin above the chassis and placed within the operable space of the cabin door, so that the refueling operation is convenient when the door is opened.
[0036] Specifically, the refueling pipe 4 includes an inclined pipe section and a vertical pipe section, wherein the low end of the inclined pipe section is connected to the fuel tank 2, the high end of the inclined pipe section is connected to the lower end of the vertical pipe section, and the upper end of the vertical pipe section passes upward through the chassis and is located at the side of the cabin.
[0037] This embodiment also provides connecting joints 10 on the top plate of the fuel tank 2 and the upper part of the vertical pipe section of the refueling pipe 4, and the connecting pipe 5 is connected between the two connecting joints 10 to facilitate the rapid discharge of gas in the fuel tank through the refueling port.
[0038] The top of the oil tank 2 is also provided with an oil return pipe 6, an oil inlet pipe 7 and a liquid level gauge flange 8 to facilitate the connection of various components. An oil drain port 9 is provided at the bottom of the oil tank 2.
[0039] This design eliminates the space limitations of side-mounted fuel tanks by mounting the fuel tank in the center of the trailer chassis frame. For chassis with no space limitations, the space originally reserved for the fuel tank can be freed up to accommodate other functional devices, such as tool boxes and boarding steps.
[0040] Example 2:
[0041] The difference between this embodiment and the first embodiment is that the refueling pipe 4 extends to the side of the trailer chassis frame and is located below the chassis.
