[0002] With the development of the automotive industry and the diverse needs of automotive users, and along with the increase in the long-distance transportation scenarios of tractors, the driver's demand for large-capacity fuel tanks is further increasing. In order to improve the cruising range, it is necessary to arrange the fuel tank with the largest volume within the space of the same wheelbase.

[0003] The existing large-capacity fuel tank chassis layout solutions for diesel commercial vehicles usually adopt the layout of double fuel tanks with similar volumes and maximize the fuel tank volume. The overall chassis layout structure is completely different from the ordinary single fuel tank layout solution, which will bring an increase in the types and costs of NPI parts to a certain extent, increasing the production manufacturing and maintenance costs. Moreover, the modularity of this layout solution is relatively low, and the generalization rate and derivative ability are not high. At the same time, the fuel tank volume requirements of existing diesel commercial vehicles mostly fall between the volumes of single fuel tanks and double fuel tanks, that is, using only one fuel tank cannot meet the needs of users, while using double fuel tanks will cause waste of resources.

With this setting, when selecting different-capacity batteries, the position of the second front bracket 400 can be ensured to remain unchanged, and only the position of the second rear bracket 500 is moved back and forth without affecting other structural modules.

[0036] Optionally, in order to further enhance the connection stability and reliability of the first mounting member, the commercial vehicle chassis layout structure further includes a second connecting member.
