The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.

[0033] Referring to Figures 1 to 5 The utility model discloses an easy dismounting rotatory calibration cover, including rotatory cover body 1, calibration cover body 2 and sealing cover 3, calibration cover body 2 rotates and installs on the one side of rotatory cover body 1, and sealing cover 3 is installed on the other side of rotatory cover body 1, the center of rotatory cover body 1 is equipped with bearing mounting hole 4, and bearing 5 is installed in bearing mounting hole 4, and the center of calibration cover body 2 extends the limit table 20 of integrated molding towards rotatory cover body 1, and the center of limit table 20 extends the calibration shaft 6 of integrated molding towards rotatory cover body 1, and calibration shaft 6 is installed in bearing 5.

[0034] Referring to Figures 3 to 4 As shown in the figure, the rotatory cover body 1 extends the bearing limiting ring 7 of integrated molding for tightly pressing the outer ring of bearing 5 to prevent bearing 5 from moving to the side of calibration cover body 2 in bearing mounting hole 4 towards the one end of calibration cover body 2, and the end of calibration shaft 6 is equipped with the snap ring installation groove 8, and the snap ring 9 is installed on the snap ring installation groove 8, and the snap ring 9 is located on the side of bearing 5 away from calibration cover body 2.

[0035] By adopting the technical scheme, calibration shaft 6 limits the lateral movement of bearing 5 through snap ring 9 to prevent bearing 5 from moving to the side of sealing cover 3.

[0036] Referring to Figures 3 to 5 As shown in the drawings, the side of the rotating cover 1 facing the calibration cover 2 is integrally formed with a water blocking ring 10 extending to the calibration cover 2. The side of the calibration cover 2 facing the rotating cover 1 is integrally formed with a counterweight 11 offset from the center of the calibration cover 2, and the side of the counterweight 11 facing the rotating cover 1 is provided with a clearance groove 12 along the circumferential edge of the calibration cover 2, which is concave and matches the shape of the water blocking ring 10.

[0037] By adopting the above technical solution, the water blocking ring 10 blocks the water entering from the gap between the circumference of the calibration cover 2 and the rotating cover 1, and the water flows out from the circumference of the water blocking ring 10 to the bottom of the rotating cover 1 and is discharged, preventing the calibration shaft 6 from being eroded by water and causing the calibration cover 2 to rotate smoothly relative to the rotating cover 1. By integrally forming the counterweight 11 on the side of the calibration cover 2 facing the rotating cover 1, the rotating cover 1 remains stationary under the weight of the counterweight 11 when the hub rotates, preventing the hub end cover from rotating with the hub and affecting the visual effect of the vehicle brand during driving.

[0038] Referring to Figure 3 and Figure 6 As shown in the drawings, the circumference of the rotating cover 1 is provided with a drainage groove 13.

[0039] By adopting the above technical solution, the water entering from the gap between the rotating cover 1 and the hub flows through the drainage groove 13 to the bottom of the rotating cover 1 and is discharged from the drainage groove 13 at the bottom, preventing the water from entering the rotating cover 1 through the gap between the rotating cover 1 and the sealing cover 3 and causing the bearing 5 and the calibration shaft 6 to rust, and avoiding the phenomenon of the calibration shaft 6 being eroded by water and causing the calibration cover 2 to rotate smoothly relative to the rotating cover 1.

[0040] Referring to Figure 3 , Figure 6 and Figure 8 As shown in the drawings, the side of the rotating cover 1 facing the sealing cover 3 is provided with at least one sealing cover screw hole 14, and the sealing cover 3 is provided with a sealing cover mounting hole 15 corresponding to the sealing cover screw hole 14.

[0044] Referring to Figure 2 , the limiting table 20 is coaxially arranged with the calibration shaft 6, and the diameter of the limiting table 20 is greater than that of the calibration shaft 6.

[0045] By adopting the technical scheme, after the limiting table 20 passes through the bearing limiting ring 7, the inner ring of the bearing 5 is abutted to prevent the outer ring of the bearing 5 from being in contact with the calibration cover body 2 to generate friction, thereby avoiding the rotating cover body 1 from driving the calibration cover body 2 to rotate.

[0046] Referring to Figure 10 , the circumferential edge portion of the rotating cover body 1 extends to the calibration cover body 2 and is integrally formed with a mounting limiting ring 21 for preventing the rotating cover body 1 from sinking into the hub shaft hole, the inner diameter of the inner circumferential surface of the mounting limiting ring 21 gradually increases in the direction facing the calibration cover body 2, and the water blocking ring 10 is located in the mounting limiting ring 21.

[0047] By adopting the technical scheme, the above structure design makes the water entering from the gap between the rotating cover body 1 and the calibration cover body 2 discharged from the rotating cover body 1 when the water reaches the lowest position of the inner circumferential surface of the mounting limiting ring 21, preventing the water from entering the rotating cover body 1 through the gap between the rotating cover body 1 and the sealing cover 3 to cause the bearing 5 and the calibration shaft 6 to rust, which avoids the calibration shaft 6 from being eroded by water to cause the calibration cover body 2 to be not smoothly rotated relative to the rotating cover body 1.

[0048] The detachable rotating calibration cover is preferably made of stainless steel. The detachable rotating calibration cover made of stainless steel has stronger rigidity, greater impact resistance and better corrosion resistance than the ordinary plastic hub end cover. The overall structure of the product is optimized, and the material is optimized, so that the overall strength of the product is higher, and the problem of loosening or abnormal sound of the hub end cover is avoided. After the detachable rotating calibration cover is installed on the wheel, the wind resistance can be reduced, and the driving resistance of the vehicle can be reduced, so that the endurance of the new energy vehicle is improved. In addition, the LOGO can be customized on the calibration cover body 2 to meet the individual needs, and the problem of short service life caused by easy aging and easy breakage of the plastic hub end cover on the market is effectively solved.
