Through holes 126 are provided on the closing cover 119. The partition plate 121 is used to prevent cement from invading the interior of the closing cover 119. The inner wall of the closing cover 119 is brought into contact with the sealing plate 114, and then the connecting strip 120 of the closing cover 119 is inserted into the connecting groove 124 of another closing cover 119. At the same time, the partition plate 121 coincides with the partition groove 125, so as to realize the coincidence of the two closing covers 119. Then, by inserting bolts into the through holes 126, the connection between the closing assembly 103 and the vehicle frame is realized, thereby increasing the stability of the axle 101.

[0030] Then, the reinforcing plate 118 is fixedly connected to the support column 117 and is located on the outer wall of the support column 117. And the reinforcing plate 118 is fixedly connected to the fixing ring 115. The reinforcing plate 118 is used to increase the stability between the support column 117 and the fixing ring 115.

At the same time, the connecting column 112 squeezes the extrusion block 109, pushing the push column 107 to move along the fixed ring 108 towards the outside of the fixed disk 104, and also squeezing the spring 105 on the fixed ring 108. Then, the push column 107 pushes the clamping column 106 into the corresponding position on the vehicle frame. When the connecting column 112 is inserted to the inner top wall of the fixed disk 104, rotate the connecting column 112 to clamp the fixed block 113 between the inner top wall of the fixed disk 104 and the clamping plates 110. Then, place the closing cover 119 on one side of the sealing plate 114, insert the connecting strip 120 on the closing cover 119 into the connecting groove 124 on the other closing cover 119, and at the same time align the partition plate 121 with the partition groove 125, so as to achieve the coincidence of the two closing covers 119. Then, insert bolts into the through holes 126 to realize the connection between the closing assembly 103 and the vehicle frame. Then, sleeved the fixed ring 115 in the sleeved groove 123 on the axle 101, and then by rotating the fixed bolt 116, insert the fixed bolt 116 into the threaded hole to sleeved and fix the fixed ring 115 on the axle 101. Therefore, through the above fixing method, the fixing operation of the axle 101 and the vehicle frame is realized, thereby increasing the stability of the axle 101.
