Integrated axle assembly and structural assembly

An integrated axle assembly comprising an axle tube assembly and a guide arm assembly, characterized in that said guide arm assembly comprises:

• a front support arm, said front support arm being cast integrally with the axle tube assembly;
• a rear support arm, said rear support arm being fixedly connected to a side of the axle tube assembly away from the front support arm;
• said rear support arm is pinned and bolted to the axle tube assembly, and said rear support arm comprises an upper support plate, a lower support plate, an upper fixed seat, a lower fixed seat and a gas spring transition plate mounting tab, said upper fixed seat and lower fixed seat are fixedly connected to the same end of the upper and lower support plates, said upper support plate is fixedly connected to the lower fixed seat and the gas spring transition plate mounting tab is connected to the upper support plate at an end away from the upper fixed seat, said upper support plate is fixedly connected to the lower fixed seat, and said gas spring transition plate mounting tab is connected to the upper support plate at an end away from the upper fixed seat, away from one end of the upper fixed seat, the bottom end of said gas spring transition plate mounting tab is fixedly connected to one end of the lower support plate away from the lower fixed seat, the thickness of said upper support plate and lower support plate cross-section is gradually thinning and narrowing from the root to the front end, and the thickness of said lower support plate is greater than the thickness of the upper support plate;
• wherein a middle reinforcing bar fixedly connected in the middle between said upper supporting plate and lower supporting plate, and there is a front reinforcing bar on the side of said middle reinforcing bar far away from the lower fixing seat, and the two ends of said front reinforcing bar are respectively fixedly connected with the opposite sides of the upper supporting plate and the lower supporting plate, and there is a bottom reinforcing bar on the side of said middle reinforcing bar far away from the front reinforcing bar, and the bottom reinforcing bar is fixedly connected to the outer walls of the lower supporting plate and the lower fixing seat on the bottom and the one side respectively, said bottom reinforcing bar is fixedly connected to the outer wall of the lower support plate and the lower fixing seat respectively, and said rear reinforcing bar is fixedly connected between said lower fixing seat and the upper support plate;
• said rear reinforcement bar is connected to the root of the upper support plate at a forward position, and said rear reinforcement bar and the outer wall of the connection between the lower support plate and the lower fixed seat are provided with chamfered corners.
