A damping member 17 is provided on the outer outer wall of the thrust block 20, and the damping member 17 is located between the push plate 19 and the inner bottom end of the U-shaped cavity 16. The damping member 17 can increase the elasticity of the tool and provide protection to a certain extent, making it easy to use. When the staff disassembles the bearing, the gripping hook 10 on the pulling claw rod 9 is located between the T-shaped member 15 and the bearing inner ring 14, and the pulling claw rod 9 is pulled under the action of the tightening connecting ring 8 so that the pulling claw rod 9 and the gripping hook 10 shrink inward, so that the gripping hook 10 is tightly fitted with the bearing inner ring 14U cavity 16 on the wheel drive hub 11, thereby playing a tightening role and preventing the pulling claw rod 9 and the gripping hook 10 from falling off during the disassembly process. A top mounting cover plate 2 is installed on the upper surface of the bearing sleeve 1, and a tightening groove 3 is provided at the center position of the upper surface of the top mounting cover plate 2, and a top mounting rod 5 is installed inside the tightening groove 3.

[0022] The bottom end of the spline key shaft 12 and the bottom end of the bearing inner ring 14 are both mounted on the T-shaped piece 15, and the T-shaped piece 15 is located at the center of the upper surface of the wheel transmission hub 11. The T-shaped piece 15 is located at the center of the upper surface of the wheel transmission hub 11. The top mounting cover plate 2 is fixed at the center of the upper surface of the wheel transmission hub 11. The top connecting plate 6 is rotated with a wrench to rotate the top mounting rod 5. The tightening thread 4 on the outer wall of the top mounting rod 5 is engaged with the internal thread in the hole wall of the tightening groove 3, so that the top mounting rod 5 moves downward and compresses the push plate 19. The push plate 19 compresses the damping member 17 and pushes the thrust block 20 downward so that the bearing inner ring 14 can be removed.

[0023] The upper surface edge of the wheel drive hub 11 is evenly spaced with fixing bolts along the circumferential direction, and the push plate 19 is located inside the U-shaped cavity 16, and the U-shaped cavity 16 is set at the center of the upper surface of the bearing sleeve 1. The upper surface edge of the wheel drive hub 11 is evenly spaced with fixing bolts along the circumferential direction. When the staff needs to disassemble the bearing on the automobile wheel drive hub 11, they hold the bearing sleeve 1 by hand and align the lower pulling claw rod 9 with the flower-shaped key shaft 12 on the wheel drive hub 11, insert the gripping hook 10 between the T-shaped piece 15 and the inner ring 14 of the bearing, and then insert the tightening connection ring 8 into the outer side of the pulling claw rod 9 to tighten and fix it. The third connection groove 18 is located at the bottom center of the U-shaped cavity 16, and the second connection groove 13 is located at the upper surface center of the flower-shaped key shaft 12.

[0024] Working principle: During use, when the staff needs to disassemble the bearing on the automobile wheel drive hub 11, hold the load-bearing sleeve 1 by hand and align the pulling claw rod 9 below with the flower-shaped key shaft 12 on the wheel drive hub 11 and insert it, insert the grab hook 10 between the T-piece 15 and the bearing inner ring 14, and then put the tightening connecting ring 8 into the outside of the pulling claw rod 9 to tighten and fix it, fix the top mounting cover plate 2 and use a wrench to rotate the top connecting plate 6 so that the top mounting rod 5 rotates, and the tightening thread 4 on the outer wall of the top mounting rod 5 is engaged with the internal thread in the hole wall of the tightening groove 3, so that the top mounting rod 5 moves downward and compresses the push plate 19, and the push plate 19 compresses the damping member 17 and pushes the thrust block 20 downward so that the bearing inner ring 14 can be removed, which is easy to operate and can be completed by one person. The damping member 17 can increase the elasticity of the tool and protect it to a certain extent. The invention relates to a novel method of reducing the bearing of the present invention, and it is convenient to use. When the staff disassembles the bearing, the gripping hook 10 on the pulling claw rod 9 is located between the T-piece 15 and the bearing inner ring 14, and the pulling claw rod 9 shrinks the pulling claw rod 9 and the gripping hook 10 inward under the action of the tightening connecting ring 8, so that the gripping hook 10 is tightly fitted with the U-shaped cavity 16 of the bearing inner ring 14 on the wheel transmission hub 11, thereby playing a tightening role, avoiding the pulling claw rod 9 and the gripping hook 10 from falling off during the disassembly process, and also ensuring a certain degree of operational safety. When the staff disassembles the bearing, the bottom of the thrust block 20 is inserted into the second connecting groove 13 on the flower-shaped key shaft 12, and the upper edge of the thrust block 20 is smaller than the outer edge size of the flower-shaped key shaft 12, so that when the thrust block 20 pushes the flower-shaped key shaft 12 downward, it can be subjected to two opposite forces, thereby facilitating the disassembly of the bearing inner ring 14, saving time and effort, and having strong practicality.
