[0028] The air reservoir 16 is arranged on the inner side of the left and right longitudinal beams of the frame 2;

[0029] A spare tire lifter and spare tire 17 are arranged in the middle of the rear overhang of the frame 2;

[0030] The vacant areas on both sides of the vehicle frame 2 between the front and rear axles can be used to install differentiated functional components such as a fuel tank for a fuel-type independent heater, a tool box, a sprinkler, etc.

[0031] The double-side-mounted LNG gas vehicle chassis, wherein the steering gear 5 and its accessory components can be freely adjusted at the symmetrical positions of the left and right longitudinal beams according to the left and right rudder models.

[0032] The double-side-mounted LNG gas vehicle chassis, in which the engine 3 can be expanded to other models under the premise of meeting the layout requirements.
