[0005] The connection structure includes middle connection flanges symmetrically arranged at one end of the middle housing and side flanges arranged at one end of the side housing. A half connection shell that is buckled with each other is installed between the middle connection flanges and the side flanges. The half connection shell includes two vertical flanges that respectively fit with the middle connection flanges and the side flanges. A C-shaped pipe is arranged between the two vertical flanges. Two transverse flanges are symmetrically arranged on the C-shaped pipe. Sealing sleeves are symmetrically and movably sleeved on the middle housing and the middle connection flanges, and on the side housing and the side flanges.
[0006] Preferably, a connection bolt penetrates through the transverse flange, and a connection nut is sleeved on the connection bolt.
[0007] Preferably, the two vertical flanges are respectively connected to the middle connection flange and the side flange through fixing bolts, and fixing nuts are sleeved on the fixing bolts.
[0008] Preferably, the C-shaped pipe, the two vertical flanges and the two transverse flanges are of an integral structure.

[0010] Preferably, the number of the threaded holes is at least one.
[0011] Beneficial effects
[0012] The utility model provides a combined drive axle housing. Compared with the prior art, it has the following beneficial effects: The drive axle housing is divided into a middle housing, two side housings and two connection structures, realizing the segmented splicing combination of the drive axle housing, facilitating the transportation of the drive axle housing. In the target area, the middle housing, the two side housings and the two connection structures are spliced together, which is convenient to operate. The connection structure adopts two mutually fitting half connection shells. When it is necessary to observe the inside of the drive axle housing, one of the half connection shells can be disassembled, which is convenient to observe the state of the internal components of the drive axle housing and is convenient for maintenance. The two closed sleeves on both sides are buckled together to shield and protect the connection parts of the middle housing, the two side housings and the two connection structures.
