The split differential housing consists of a left differential housing and a right differential housing.

[0027] Specifically, the disassembly mechanism 6 includes: a threaded groove 61, a nut 62, a clamping groove 63, a clamping spring 64, a slider 65, a clamping column 66, a rotating handle 67, a mounting groove 68, and a positioning hole 69. The outer wall of the right bearing mounting portion 4 is provided with a threaded groove 61, which can facilitate the rotation of the nut 62. The front surface of the right bearing mounting portion 4 is threadedly connected with the nut 62, which can cover the disassembly mechanism 6 to prevent it from falling off, and can squeeze the slide bar 72 to move downward. The inner ring of the outer wall of the right bearing mounting portion 4 is provided with a clamping groove 63, which is convenient for installing the clamping spring 64. The left side of the clamping groove 63 is fixedly connected with the clamping spring 64, which can reset the slider 65. The slider 65 and the clamping spring 64 are fixedly connected with the slider 65 at one end away from the left side of the clamping groove 63, which can facilitate the rotation of the clamping column 66. The slider 65 The sliding connection in the clamping groove 63 can provide a guiding effect for the slider 65. A clamping column 66 is rotatably installed on the left side of the slider 65, which can be clamped into the positioning hole 69 to fix the reinforcing rib 5. The clamping spring 64, the slider 65, and the clamping column 66 are distributed in a circular array with the center of the right bearing mounting portion 4, so that each reinforcing rib 5 can be disassembled individually, and the nut 62 will not fall off completely when the nut 62 is unscrewed. The outer wall of the clamping column 66 is fixedly installed with a rotating handle 67, which is convenient for rotating the clamping column 66 and pushing the clamping column 66 to move, thereby disengaging from the positioning hole 69. The inner ring of the outer wall of the right bearing mounting portion 4 is provided with a mounting groove 68, which is convenient for installing the reinforcing rib 5. A positioning hole 69 is provided on the right side of the reinforcing rib 5, which can prevent the reinforcing rib 5 from falling off when the clamping column 66 is clamped in.

[0028] The cam 76 is a substantially parallelogram of the cam 76, which is a substantially uniform scale and is preferably used to define the cam 76. The cam 76 is a substantially uniform scale and is preferably used to define the cam 76. The cam 76 is a substantially uniform scale and is preferably used to define the cam 76. The cam 76 is a substantially uniform scale and is preferably used to define the cam 76. When rod 72 moves up and down, it drives push plate 75 to move left and right. The end of connecting rod 74 away from sliding rod 72 is hinged with push plate 75, which can push extrusion spring 76 to move. Push plate 75 is slidably connected in convex groove 71, and extrusion spring 76 is fixedly connected to the bottom of push plate 75. Connecting rod 74, push plate 75, and extrusion spring 76 are arranged in two groups, and are symmetrical about the central symmetry axis of the top of sliding rod 72, and are symmetrically distributed on the left and right sides of sliding rod 72, so that the two reinforcing ribs 5 can be clamped. The end of extrusion spring 76 away from push plate 75 is fixedly installed with extrusion plate 77, which can squeeze the reinforcing rib 5 to make the reinforcing rib 5 more stable in the mounting groove 68, and the extrusion plate 77 is slidably connected in the convex groove 71.

[0029] Working principle: When the reinforcing rib 5 is fatigue-fractured, the reinforcing rib 5 can be displayed by rotating the nut 62 to move outward in the threaded groove 61, and then pulling out the rotating handle 67 and pushing it to the right can drive the clamping column 66 to be pushed to the right. At the same time, the clamping column 66 disengages from the positioning hole 69 and drives the slider 65 to move to the right, and the clamping spring 64 is compressed, so that the reinforcing rib 5 can be removed and replaced one by one, and the clamping column 66 of the one that needs to be removed is pushed. After the replacement is completed, the clamping column 66 is inserted into the positioning hole 69 of the replaced reinforcing rib 5, and then the rotating handle 67 is rotated into the clamping groove 63. The reinforcing rib 5 can be fixed in the inner ring of the outer wall of the right bearing mounting part 4 by rotating the nut 62, which can save costs and facilitate replacement.

[0030] When replacing the reinforcing rib 5, there may be a little deviation, causing the reinforcing rib 5 to shake in the installation groove 68. The nut 62 can be rotated to squeeze the back side of the nut 62 to squeeze the slide bar 72, and the slide bar 72 slides in the convex groove 71, and the return spring 73 is compressed. When moving backward, the connecting rod 74 is driven to make the push plate 75 move to both sides in the convex groove 71, so that the push plate 75 can squeeze the extrusion spring 76, and the extrusion spring 76 will push the extrusion plate 77 to squeeze the reinforcing rib 5, so that the reinforcing rib 5 can be well fixed. When replacing, the return spring 73 will drive the slide bar 72 to move upward, so that the extrusion plate 77 does not clamp the reinforcing rib 5, which is convenient for replacement.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
