造に関する。[Detailed description of the invention] The present invention relates to a mounting structure for a hub bearing cap used on the front axle of an automobile, and in particular effectively uses grease for lubrication of the outer bearing to improve the sealing performance of the hub bearing cap. This invention relates to a hub bearing cap mounting structure that prevents water from entering the hub bearing cap.

２ａに圧入固定されている。 First, a conventional example of a mounting structure for a hub bearing cap 1 will be explained with reference to FIG. 1. An outer bearing 3 is press-fitted into a wheel hub 2, and supports a knuckle spindle 4 together with an inner bearing 5. The hub bearing cap 1 is press-fitted into a mounting hole 2a having a diameter approximately equal to that of the outer bearing 3.

久性が損われるという欠点があつた。 According to such a conventional example, since the outer diameter of the outer bearing 3 and the inner diameter of the hub bearing cap 1 are the same, the grease 6 filled for bearing lubrication is applied to the cap 1 as shown by the dotted pattern in the figure. If the cap 1 is improperly assembled, such as being installed at an angle, water may leak in from the outside, resulting in a considerable amount of water being wasted.
This has the drawback of causing poor lubrication of the outer bearing 3 and impairing its durability.

ある。 The present invention was made to eliminate the drawbacks of the prior art described above, and its purpose is to eliminate waste of grease for bearing lubrication, and to
By storing a portion of the grease in a grease reservoir that is quite deep in the radial direction, the sealing performance of the hub bearing cap is improved. The objective is to prevent the bearing from penetrating into the bearing, thereby fully demonstrating its inherent durability.

ある。 In short, the present invention is such that the diameter of the outer hub bearing cap mounting hole into which the outer bearing is press-fitted is larger than the diameter of the outer bearing, and the diameter of the inner circumferential surface of the hub bearing cap is larger than that of the mounting hole. A bent portion is provided that is smaller than the diameter at least twice the plate thickness of the hub bearing cap on one side, and a considerably deep grease reservoir is provided in the radial direction between the bent portion and the outer bearing. It is characterized by:

なつている。 The present invention will be explained below based on embodiments shown in the drawings. What is shown in FIG. 2 is a first embodiment of the present invention, in which a hub bearing cap 7 is provided on the outside of the outer bearing 3 of the wheel hub 2 to which the outer bearing 3 supporting the nutcle spindle 4 is press-fitted. A mounting hole 2a is provided, and the diameter of the mounting hole is considerably larger than the diameter of the outer bearing 3. On the other hand, the hub bearing cap 7 is formed with a bent portion 7b such that the diameter of the inner circumferential surface 7a is substantially smaller than the diameter of the mounting hole 2a, that is, at least twice the thickness of the hub bearing cap 7 on one side. A considerably deep grease reservoir 8 is formed in the radial direction between the bent portion and the outer bearing 3. The grease reservoir 8 is a space surrounded by the bent portion 7b, the thrust washer 9, the outer bearing 3, and the wheel hub 2.

１実施例と同様である。 What is shown in FIG. 3 is a second embodiment of the present invention, in which the end 7c of the hub bearing cap 7 is inserted into the mounting hole 2a.
The cap is fully inserted, and a bent portion 7b is provided in the middle to make the cap smaller in diameter. Therefore, the depth of the mounting hole 2a of the cap is shallower than that of the first embodiment. Similarly, a considerably deep grease reservoir 8 is formed in the radial direction between the bent portion 7b and the outer bearing 3. The other thrust washers 9 and nutacle spindle 4 are the same as those in the first embodiment.

る。 What is shown in FIG. 4 is a third embodiment of the present invention.
The attachment hole 2a of the hub bearing cap 7 to the wheel hub 2 is formed deeply as in the first embodiment, and in addition to providing a bent part 7b, another fold is provided horizontally inward from the bent part 7b. A bent portion 7b' is provided, and when installed, the end portion 7c is inside the thrust washer 9.
A considerably deep grease reservoir 8 is formed in the radial direction between 7b' and the outer bearing 3. The knuckle spindle 4 is the same as in each of the above embodiments.

In the figure, as shown by the dotted pattern, the grease accumulates in a considerably deep grease reservoir 8 in the radial direction, and when the wheel hub 2 rotates while the car is running, the centrifugal force presses the grease 6 against the outer circumference with strong pressure. is hub bearing cap 7 and wheel hub 2
The space between the vehicle and the mounting hole 2a is completely sealed, and even if water or the like tries to enter from the outside while the vehicle is running, this is blocked and water intrusion is prevented.

Since the cap 7 is blocked by b, it is difficult for the cap 7 to move further to the right in the figure, so the grease 6 does not leak all over the inside of the cap 1 as in the conventional example, and waste of the grease 6 can be avoided. .

十分に発揮される効果が得られる。 Since the present invention is constructed and operates as described above, it is possible to eliminate waste of grease for bearing lubrication in the front axle of an automobile, and also to prevent the lubrication grease from collecting in a considerably deep grease pool in the radial direction. This is constantly stored in the hub bearing cap and improves the sealing performance of the hub bearing cap, thereby accurately preventing water from entering the hub bearing cap from the outside even in the case of a slight assembly failure. You can get the same effect. This also provides the effect of fully demonstrating the inherent durability of the bearing.
