The use of wheels has also promoted the development of contemporary cars. However, wheels are consumables, and it is also common to have a tire blowout on the road, so it is necessary to disassemble the wheel and replace the spare tire. The wheel needs the cooperation of the bearing during operation, and the bearing needs to be connected to the wheel, so whether the wheel and the bearing are centered is a very important issue.a. When a vehicle has a tire blowout, it is necessary to use professional tools in the trunk to remove the bolts on the wheel. The disassembly process is relatively cumbersome and cannot achieve the effect of quickly replacing the spare tire. In addition, people in daily life do not fully understand the method of replacing the spare tire. Many people do not know how to replace the spare tire, which brings great inconvenience to the replacement. The wheel cannot be disassembled quickly, which not only affects the replacement time, but also makes people's operation more cumbersome. b. Traditional wheel bearings are connected to the vehicle drive shaft, and the wheels are connected to the bearings. However, due to matching problems, the wheels and bearings are not concentric, which causes the wheels to be unable to rotate concentrically with the shaft during operation, resulting in shaking during vehicle driving, which seriously affects riding comfort and driving safety.

At the same time, the fixing device 4 passes through the center hole of the centering device 5 and is connected to the first bearing 7, so that the wheel hub 2 and the first bearing 7 are at the same center of a circle. Since the centering device 5 is completely connected to the wheel hub 2, the center of the circle between the two devices is determined and will not move, so the wheel will not shake during operation. The connecting bolt 8 passes through the hole 9 to connect the first bearing and the locking device 6 together. The two mechanisms are tightly connected together through the bolt connection. When the locking device 6 is working, it will extend the connecting pin 622, and the connecting pin 622 connects the first bearing 7 and the centering device 5 together, and then locks them through the connecting bolt 8 to achieve the purpose of the centering connection.

[0023] Specifically, the locking device 6 includes a positioning block 61, a connecting assembly 62, a moving rod 63, a rotating assembly 64, a spring 65 and a first base 66. The positioning block 61 for matching the locking device 6 and the centering device 5 is welded on the first base 66. The connecting assembly 62 for fixing the two devices is located inside the positioning block 61. The moving rod 63 for moving the connecting assembly 62 is welded to the connecting pin 622. The rotating assembly 64 is located below the moving rod 63. The rotating assembly 64 is rotatably connected to the moving rod 63. The spring 65 is located on the end face of the moving rod 63 and is welded to the end face of the moving rod 63. The positioning block 61 cooperates with the positioning block 54 on the centering device 5. When the wheel is connected to the first bearing 7, the connecting pin 622 enters the positioning block 54. The limiting hole 52 makes the first bearing 7 and the wheel firmly connected together. When the tire is removed, the fixing device 4 is rotated to make the rotating assembly 64 rotate, thereby driving the moving rod 63 to move. The movement of the moving rod 63 drives the connecting assembly 62 to move, so that the centering device 5 is disconnected from the first bearing 7, thereby removing the wheel. When installing the wheel, first connect the centering device 5 and the locking device 6 on the wheel, and rotate the fixing device 4. Due to the rotation of the fixing device 4, the rotating assembly 64 is driven to rotate, so that the connecting assembly 62 is opened, and the two devices are connected. Since a spring 65 is installed under the moving rod 63, after the installation is completed, the spring 65 will automatically pop out to fix the connecting assembly 64 in the limiting hole 52 to ensure that the connection between the wheel and the first bearing is firm.

[0024] Specifically, the connecting assembly 62 includes a slider 621, a connecting pin 622 and a slide rail 623, the connecting pin 622 is located on the upper end surface of the moving rod 63, the connecting pin 622 is welded on the upper end surface of the moving rod 63, the slide rail 623 is located on the upper and lower end surfaces of the connecting pin 622, the slide rail 623 is installed on the connecting pin 622, and the slide rail 623 is slidably connected to the slider 621; when the moving rod 63 moves, the connecting pin 622 connected to the moving rod 63 will move accordingly, the slider 621 is fixed on the first base 66, and when the connecting pin 622 moves, the slide rail 623 installed on the connecting pin 622 will move on the slider to ensure that its movement trajectory remains fixed.

[0025] Specifically, the rotating assembly 64 includes a spur rack 641, a gear A 642, a shaft 643, a gear B 644, a second bearing 645, a groove 646 and a center hole 647. The rack 641 is welded to the moving rod 63, the shaft 643 is installed on the first base 66, the shaft 643 is installed with a gear A 642, the gear A 642 is connected to the rack 641, the gear B 644 is meshed with the gear A 642, a center hole 647 is opened at the center of the gear B 644, the center hole 647 is surrounded by grooves 646, and the grooves 646 are arranged at 90 degrees in the center hole 647; when the fixing device 4 rotates, the key on the fixing device 4 will be inserted into the groove on the center hole 647, thereby driving the external gear B 642 to rotate, and the gear B A second bearing 645 is installed in the middle of 644. When gear B rotates, it will drive gear A642 to rotate. A shaft 643 is installed in the middle of gear A642, so that gear A642 can rotate freely. When gear A642 rotates, it drives rack 641 to move. The movement of rack 641 will drive moving rod 63 to move, thereby moving connecting pin 622.

[0026] Specifically, the centering device 5 includes a centering hole 51, a limiting hole 52, a limiting block 53 and a sleeve 54. The sleeve 54 is welded to the wheel spoke 3. The center of the sleeve 54 is provided with a centering hole 51. The limiting block 53 is installed on one side of the sleeve 54. The limiting hole 52 is provided inside the limiting block 53. The limiting block 53 is connected to the locking device 6 when connected. The sleeve 54 is connected to the wheel spoke 3 to ensure that the center of the wheel remains unchanged. The centering hole 51 is located in the middle of the sleeve and cooperates with the fixing device 4 to ensure that the wheel and the first bearing 7 are at the same center. When the wheel and the first bearing 7 are connected, the connecting pin 622 will cooperate with the limiting hole 52 to achieve the purpose of connecting the mechanisms.

[0027] The fixing device 4 includes a stud 41, a key 42, a second base 43 and a rotating handle 44. The stud 41 is connected to the second base 43, the key 42 is installed on the surface of the stud 41, and the rotating handle 44 is installed below the second base 43. When the fixing device 4 cooperates with the locking device 6, the key 42 installed on the stud 41 will cooperate with the groove 646 in the rotating assembly 64, and then the rotating handle 44 is rotated, the stud 41 also rotates, driving the rotating assembly 64 to rotate, so that the mechanisms are separated and the wheel is removed.

[0028] The working principle of the present invention is:

[0029] Wheel disassembly process: When the wheel needs to be disassembled, first rotate the rotating handle 44 on the fixing device 4. When the rotating handle 44 is rotated, it will drive the rotating assembly 64 to rotate. The rotation of the rotating assembly 64 drives the movement of the moving rod 63, so that the connecting pin 622 connected to the moving rod 63 extends from the hole of the centering device 5, thereby disconnecting the wheel from the first bearing 7 and removing the wheel.

[0030] Wheel installation process: When installing the wheel, first put the wheel on the first bearing 7, and the limit block 53 on the centering device 5 on the wheel cooperates with the locking device 6. When the position is determined, pass the fixing device 4 into the centering hole of the centering device 5, and rotate the fixing device 4. The rotation of the fixing device 4 drives the rotation of the gear B644. The rotation of the gear B644 causes the moving rod 63 to move. The movement of the moving rod 63 drives the connecting pin 622 to open. After the wheel is installed in place, due to the action of the spring 65, after the fixing device 4 is released, the connecting pin 622 will automatically close to tightly connect the wheel and the first bearing 7.
