When the drive axle housing needs to be used, the staff first moves the plug plate 45, the plug plate 45 enters the inside of the groove 43, the spring 44 is contracted, then the staff moves the reinforcing rib 42, the reinforcing rib 42 enters the inside of the mounting groove 41, then the staff releases the plug plate 45, under the action of the reset spring force of the spring 44, the plug plate 45 enters the plug hole 46 of the reinforcing rib 42, which achieves the effect of fixing the reinforcing rib 42. The reinforcing rib 42 provided by the reinforcing device 4 increases the overall strength of the sleeve 2 at both ends of the shell 1, avoids damage to the sleeve 2 after long-term use, and improves the service life of the sleeve 2.

[0031] Referring to Figures 1-5 As shown, one end of the plug plate 45 is fixedly connected with a sharp protrusion 49, the sharp end of the sharp protrusion 49 is away from the plug plate 45. By setting the sharp protrusion 49, the staff can conveniently insert the plug plate 45 into the plug hole 46 of the reinforcing rib 42, which brings convenience to the staff. One side of the plug plate 45 is fixedly connected with an extension rod 47, one end of the extension rod 47 is fixedly connected with the inner wall of the groove 43. By setting the extension rod 47, the moving direction of the plug plate 45 is limited, which improves the stability of the plug plate 45 movement. One side of the plug plate 45 is fixedly connected with a pull plate 48, the cross section of the pull plate 48 is rectangular. By setting the pull plate 48, the contact area between the staff's hand and the plug plate 45 is increased, which further brings convenience to the staff to move the plug plate 45.

[0032] Referring to Figures 1-5As shown, the auxiliary device 5 includes a clamping groove 51, which is arranged on the upper surface of the mounting frame 3. The mounting frame 3 is provided with a rubber pad 52 through the clamping groove 51. The thickness of the rubber pad 52 is greater than that of the clamping groove 51. The inside of the mounting frame 3 is slidably connected with a moving plate 53. The upper surface of the moving plate 53 is fixedly connected with a top plate 54 through a supporting rod.

Both ends of the mounting frame 3 are fixedly connected with triangular plates 58. One side of the triangular plate 58 is fixedly connected with the sleeve 2. The triangular plate 58 increases the contact area between the mounting frame 3 and the sleeve 2, thereby improving the stability between the mounting frame 3 and the sleeve 2.

[0034] Working principle: when the drive axle housing needs to be used, the staff first moves the plug-in plate 45 through the pull plate 48. The plug-in plate 45 enters the inside of the recess 43. The spring 44 and the telescopic rod 47 are contracted. Then the staff moves the reinforcing rib 42. The reinforcing rib 42 enters the inside of the mounting groove 41. Then the staff loosens the plug-in plate 45. Under the action of the reset force of the spring 44, the plug-in plate 45 enters the plug hole 46 of the reinforcing rib 42 through the sharp protrusion 49, achieving the effect of fixing the reinforcing rib 42. The reinforcing rib 42 arranged by the reinforcing device 4 increases the overall strength of the sleeve 2 at both ends of the housing 1, avoiding the damage of the sleeve 2 after a long time of use, and improving the service life of the sleeve 2.

[0035] Before needing to install the sleeve 2, the staff first inserts the rubber pad 52 into the clamping groove 51 of the mounting frame 3, fixes the rubber pad 52, and then connects the mounting frame 3 with the automobile through bolts, and the rubber pad 52 protects the connection point to avoid the wear of the mounting frame 3, when the rubber pad 52 is aging, the staff pulls the control block 55, the control block 55 moves with the moving plate 53, the moving plate 53 moves upward with the top plate 54, and the top plate 54 ejects the rubber pad 52, so that the rubber pad 52 is disassembled, and the rubber pad 52 arranged through the auxiliary device 5 can protect the connection between the mounting part and the automobile, and conveniently disassemble the rubber pad 52 when the rubber pad 52 is aging.
