2, a wheel bearing sealing apparatus 100 according to an embodiment of the present invention includes an outer ring 120, an inner ring 110, and a sealing member 130.

The outer ring 120 includes an outer ring mounting portion 122 and an outer ring extension portion 124.

The outer ring mounting portion 122 is mounted at one end of the inner peripheral surface of the outer ring 40. Here, the one end is a surface facing the outer circumferential surface of the inner ring 30. The outer ring extension portion 124 is bent at one end of the outer ring mounting portion 122 and extends integrally. That is, the outer frame 120 may be a flat plate having a single folded end and a constant thickness. Meanwhile, the outer frame 120 may be formed of a metal material.

The inner ring 110 includes an inner ring mounting portion 112, an inner first extension portion 114, and an inner second extension portion 116.

The inner ring mounting portion 112 is mounted on the outer peripheral surface of the inner ring 30. That is, the inner ring mounting portion 112 may have a shape facing the outer ring mounting portion 122. Further, the inner-ring first extension portion 114 is bent at one end of the inner-ring mounting portion 112 and extends integrally. That is, the first end-piece extension portion 114 may have a shape facing the outer-side end portion extension portion 124. Further, the second inward-facing second extending portion 116 is bent at one end of the first inward-facing first extending portion 114 and extends integrally. That is, the second inward-facing second extension portion 116 may extend toward the outer-side extension portion 124. On the other hand, the base metal 110 may be a plate-like plate having a certain thickness with two bending stages. That is, the base steel (110) may be in the shape of a " U "

The sealing member 130 is provided in an inner space formed between the outer member 120 and the inner member 110. Further, the sealing member 130 is engaged with the outer shell 120. Furthermore, the sealing member 130 includes a first lip 132, a second lip 134, a third lip 136 and a lip extension 138.

The first lip 132 is formed to be pressed onto the inner surface of the inner ring mounting portion 112. In addition, the second lip 134 is formed to be pressed against the inner surface of the first extension portion 114 of the iron. In addition, the third lip 136 is formed to be compressed to the outer surface of the inner extension portion 116 between the outer ring mounting portion 122 and the inner extension second extension 116. Meanwhile, the first lip 132, the second lip 134, and the third lip 136 may have a shape extending from the sealing member 130 coupled to the outer convex 120.

The lip extension 138 is bent and protruded from an end portion of the second lip 134 extending from the sealing member 130. In addition, the lip extension 138 extends toward the second extension portion 116 and is formed to be pressed against an inner surface of the second extension portion 116.

Therefore, a first space 140 is formed between the second lip 134 and the third lip 136 in the inner space having the sealing member 130, and the first lip 132 and the second lip are formed. The second space 142 is formed between the 134. Further, in order for foreign matter outside the wheel bearing 10 to penetrate into the space filled with the grease 60, the first space 140 and the second space 142 must be sequentially passed through. Further, in order for the grease 60 to leak to the outside, the second space 142 and the first space 140 must be sequentially passed through. That is, the penetration of the foreign matter and leakage of the grease (60) is generated only through the three pressing parts (132, 134, 136).

3 is a diagram in which the inner steel is omitted in the sealing device for a wheel bearing according to an embodiment of the present invention.

As shown in FIG. 3, the second lip 134 and the lip extension 138 are elastically applied to the outside in the state where the inner convex 110 is separated. That is, the elastic force acts in the direction in which the inner iron 110 contacts. Therefore, as shown in FIG. 2, when the inner iron 110 is coupled to the outer circumferential surface of the inner ring 30, the second lip 134 may be pressed onto the inner surface of the inner iron first extension part 114, and the lip extension 138 may be closed. The second extension part 116 may be compressed on the inner surface. In addition, even if the gap between the first extension portion 114 and the outer extension portion 124 is increased, the sealing performance of the sealing member 130 may be maintained by pressing the lip extension 138.

4 is an enlarged view of a portion “B” of FIG. 3.

As shown in FIG. 4A, the lip extension 138 may extend from the second lip 134 with a predetermined thickness. That is, in FIG. 4A, the sizes of d1 and d2 are the same.

As shown in FIG. 4B, the lip extension 138 may have a shape in which its thickness gradually increases as it extends from the second lip 134. That is, in FIG. 4B, d2 'is larger than d1'.

In addition, the shape of the lip extension 138 is not limited to the shape shown in Figs. 4 (a) and 4 (b), to increase the elastic force of the lip extension 138 or to the shape of the inner convex (110). Accordingly, it can be changed and applied by those skilled in the art to facilitate the compression with the second extension portion 116.

5 is a block diagram of a sealing device for a wheel bearing according to another embodiment of the present invention.

As shown in FIG. 5, in the sealing device for a wheel bearing according to another exemplary embodiment of the present disclosure, an included angle between the first extension part 114 and the second extension part 116 may be an obtuse angle. That is, the second inner extension part 116 is bent at an obtuse angle and extends from the first extension part 114. In addition, even if the included angle is an obtuse angle, the lip extension 138 is formed to be pressed against the inner surface of the second extension portion 116.

6 is a block diagram of a sealing device for a wheel bearing according to another embodiment of the present invention.

As shown in FIG. 6, in the sealing device for a wheel bearing according to another exemplary embodiment of the present invention, the lip extension 138 may not be pressed against the inner surface of the second inner extension part 116. That is, the separation distance is generated between the lip extension 138 and the second extension portion 116. In addition, the separation distance may occur when the included angle is larger than the set angle in the obtuse angle range or when the lip extension 138 loses the elastic force for the compression. On the other hand, those skilled in the art can change the shape of the lip extension 138 to generate the separation distance.

However, even if the separation distance in any case described above, if foreign matter penetrates into the first space 140 of the sealing device 100, the lip extension 138 by the increased pressure of the first space 140 Is compressed to the second extension portion 116. That is, foreign matter may be prevented from penetrating between the lip extension 138 and the inner surface of the second extension portion 116.

As described above, according to embodiments of the present invention, the pressing force of the sealing member 130 may be maintained even when the separation distance between the outer iron 120 and the inner iron 110 is increased. In addition, the pressing force of the sealing member 130 may be maintained even when the shape of the inner duct 110 is changed. That is, the sealing performance may be maintained even when the separation distance and shape of the outer iron 120 and the inner iron 110 are changed. Therefore, the sealing performance of the sealing device of the wheel bearing can be improved.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And all changes to the scope that are deemed to be valid.
