a second frame 200 fixed above the first frame 100, wherein the second frame 200 includes a plurality of second cross members 210 and a plurality of second longitudinal members 220, and the second cross members 210 and the second longitudinal members 220 are fixed; the second frame 200 is further provided with two wheel covers 300 above the wheel arches, and the upper surfaces of the wheel covers 300 are higher than the upper surface of the second frame 200; a reserved space 230 for routing is further opened between the two wheel covers 300.
In this embodiment, since the wheel casing 300 is higher than the upper surface of the second frame 200, compared with the structure arrangement in which the upper surface of the second frame 200 is flush with the wheel casing 300 in the prior art, the present embodiment is equivalent to reducing the overall height of the second frame 200, so that the peripheral side of the wheel casing 300 has more space, and at the same time, the structure of the whole rear axle section frame is more compact, and the space utilization rate is higher.
Further, a reserved space 230 is arranged in the middle of the second frame 200, and the reserved space 230 can be used for wiring of a wiring harness, arrangement of an air pipe and an oil pipe, and space utilization rate of the frame is further improved.
The reserved space 230 penetrates both ends of the second frame 200, and the second frame 200 is symmetrical with respect to the reserved space 230.
The reserved space 230 penetrates through two ends of the second frame 200, so that the arrangement of the wire harness, the oil pipes and the air pipes can be distributed to all positions of the second frame 200, and the wiring is more convenient; meanwhile, the second frame 200 is symmetrical about the reserved space 230, so that the routing of the left side and the right side of the second frame 200 is more uniform and compact; therefore, the left side and the right side of the second frame 200 are more balanced, the left side and the right side are stressed equally in the driving process, and left-right shaking is avoided, so that the driving texture of the automobile is improved.
Two of the wheel housings 300 are symmetrical with respect to the reserved space 230.
Further, the two wheel covers 300 are symmetrical with respect to the reserved space 230, that is, the wheels at the two wheel arches are symmetrical with respect to the reserved space 230, so that the connection of the wire harness, the air pipe and the oil pipe of the two wheels can be symmetrical with respect to the reserved space 230, and further, the mass distribution of the left side and the right side is uniform, thereby improving the driving stability of the automobile.
The wheel guard 300 includes a top plate 310 and two side plates 320, two ends of the top plate 310 are respectively connected to one side plate 320, the top plate 310 is higher than the upper surface of the second frame 200, and one end of the side plate 320, which is far away from the top plate 310, is connected to the second frame 200.
