When the hub bearing cup 110 detaching device assembled as described above is inserted into the hub 100, the sub-plates 50 and 60 are mounted on the hub bearing cup 110 as shown in FIG. 2. Due to the compression of the elastic part 70, the guide surfaces 54 and 64 are moved toward the main plate 40 and guided along the inner surface of the hub bearing cup 110. The arrows shown in the head 16 and the handle 18 of FIG. 2 show the force by which the operator pushes the hub bearing cup 110 detachment device toward the hub 100 side.

In this state, the pushing force is continuously transmitted to the subplates 50 and 60 so that the guide surfaces 54 and 64 of the subplates 50 and 60 pass through the inner surface of the hub bearing cup 110. As described above, the guide surfaces 54 and 64 are moved outwardly from the main plate 40 side by the restoring force of the elastic portion 70 so that the top surfaces 56 and 66 of the hub bearing cup 110 are moved. Support the bottom. At this time, the support 20 is in close contact with the outer surface of the hub (100). The close contact of the support 20 is made by the operator rotates the support plate 24 to close contact.

In this state, the operator rotates the handle 18 in a predetermined direction, and the main plate 40 and the subplates 50 and 60 are driven by the hub 100 according to the rotational force transmitted to the rotary rod 12 through the handle 18. ) Is moved outward from the inward direction. At this time, a force is also transmitted to the lower surface of the hub bearing cup 110 in contact with the upper surfaces 56 and 66 of the subplates 50 and 60 so that the hub bearing cup 110 is pushed out from the inner surface of the hub 100. do.

Through this process, the embodiment of the present invention can more stably remove the hub bearing cup 110 in a press-fitted state in the hub 100, and there is no damage to the quality of the product. In addition, by using the right tools in the right place, you can simplify work and reduce time and contribute to quality improvement.

On the other hand, the detailed description of the present invention has been described with reference to specific embodiments, of course, various modifications are possible without departing from the scope of the invention. In the above embodiment, the configuration of the detachable portion for the elastic movement and the hinge movement between the main plate and the sub-plate has been described, it should be noted that those skilled in the art can implement the structure of the detachable portion in various ways. For example, the rack and the pinion gear can be used to implement a variable length, and a folding detachable part using the principle of an umbrella is inserted into the hub bearing cup when inserted into the hub bearing cup. It can be configured to expand in the direction.

Therefore, it should be noted that the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims below but also by the equivalents of the claims.

As described above, the hub bearing cup detachment apparatus of the vehicle according to the present invention develops a tool for use when disassembling the hub bearing cup from the hub, thereby contributing to the improvement of quality without damaging the hub and the hub bearing cup and improving the working process. There is an effect that can be simplified.
