Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the utility model.

A brake dust cover according to an embodiment of the present utility model is described below with reference to fig. 1-7.

One embodiment of the present utility model provides a brake dust cover. In the present embodiment, the brake dust cover includes the annular plate 10, the annular plate 10 is fixedly connected with the knuckle 20, the inner edge 11 of the annular plate 10 is arranged around the connecting portion 21 of the knuckle 20, and the contour of the inner edge 11 is contoured to the outer peripheral contour of the connecting portion 21; wherein the connection portion 21 is used for connecting the hub bearing 30.

In some embodiments, the brake may be a disc brake, which includes a brake disc. The brake dust cover is arranged corresponding to the brake disc, and provides protection for the brake disc. The structure and principle of the disc brake are well known and the present embodiment is not described in detail here.

The disc brake has a brake caliper for clamping a brake disc for braking. The annular plate 10 may be divided into a first angular region and a second angular region in the circumferential direction. The first angle area is an opening, and the opening is used for avoiding the brake caliper; the annular plate 10 body is located in the second angular region.

It will be appreciated that a brake dust cover on a vehicle may include a front dust cover disposed on a front wheel of the vehicle and a rear dust cover disposed on a rear wheel of the vehicle. The front dust cover and the rear dust cover may have the same or different structures, and the present embodiment is not limited thereto.

The contour of the inner edge 11 is contoured to the outer peripheral contour of the connecting portion 21, which means that the contour of the inner edge 11 is designed to be identical or similar according to the outer peripheral contour of the connecting portion 21. Wherein the shielding effect with the same contour of the inner edge 11 is better.

It will be appreciated that the connection portion 21 of the knuckle 20 is typically bolted to the hub bearing 30. The bolts are attached to the outer periphery of the hub bearing 30, and thus the attachment portion 21 generally includes attachment holes arranged in the circumferential direction such that the outer peripheral profile of the attachment portion 21 is wavy. Of course, the outer peripheral contour of the connecting portion 21 may be set as required, which is not limited in this embodiment.

In the related art, the annular plate 10 is generally mounted by clamping or press-fitting. As shown in fig. 6, the clamping means that the annular plate 10 is sandwiched by the knuckle 20 and the hub bearing 30. As shown in fig. 7, press-fitting means that the annular plate 10 is press-fitted on the outer flange of the knuckle 20, and is pressed by interference fit. The inner ring of the annular plate 10 of this embodiment is sleeved with the knuckle 20, and the body is fixedly connected with the knuckle 20. Compared with the related art, the annular plate 10 in the present embodiment reduces unnecessary material necessary for the inner ring clamping fixation or the interference press-fitting fixation, thereby reducing the material consumption.

In some embodiments, the cross-sectional area of the connection 21 is greater than the cross-sectional area of the body of the hub bearing 30. The inner rim 11 is thus arranged around the connecting portion 21 of the knuckle 20 with a larger inner ring area of the annular plate 10 than around the body of the hub bearing 30, thereby reducing the area of the annular plate body and further reducing the amount of material.

According to the brake dust cover, the inner edge 11 of the annular plate 10 is arranged around the connecting part 21 of the knuckle 20 by adopting the profiling structure, so that the area of the inner ring is increased, the protection and shielding functions of the dust cover are reserved, the material consumption is reduced, and the weight of the dust cover is reduced.

In some embodiments, the annular plate 10 is provided with a plurality of mounting holes 12 in the circumferential direction, and the mounting holes 12 are arranged close to the inner rim 11.

In some embodiments, the mounting holes 12 may be uniformly arranged on the annular plate 10 in the circumferential direction, and the number of the mounting holes 12 may be three or four, or the like. The mounting holes 12 are used for mounting bolts to fixedly connect the annular plate 10 with the knuckle 20. The mounting holes 12 are uniformly distributed in the middle area of the annular plate and fixed on the knuckle 20, so that the stress is more reasonable, and the mode of the dust cover is improved.

In some embodiments, the annular plate 10 is provided with mounting bosses on which the mounting holes 12 are provided. The mounting boss may be raised to the side of the knuckle 20 to facilitate installation.

In some embodiments, the annular plate 10 is provided with first reinforcing ribs 13, the first reinforcing ribs 13 connecting at least two mounting holes 12.

As an example, the annular plate 10 is circumferentially provided with three mounting holes 12, and the three mounting holes 12 are located above, in the middle and below the annular plate 10, respectively, and the first reinforcing ribs 13 are arranged in at least two ways:

the first arrangement is: the annular plate 10 is provided with two first reinforcing ribs 13, the first reinforcing ribs 13 extending circumferentially from the lower mounting hole 12 to the middle mounting hole 12, and the second reinforcing ribs 13 extending circumferentially from the upper mounting hole 12 to the middle mounting hole 12.

The second arrangement is as follows: the annular plate 10 is provided with a first reinforcing rib 13, the main body portion of the first reinforcing rib 13 extending circumferentially from the lower mounting hole 12 to the upper mounting hole 12, and the branch portion of the first reinforcing rib 13 extending radially from the main body portion to the intermediate mounting hole 12.

It can be appreciated that the rigidity and the mode of the annular plate 10 are greatly improved due to the connection between the mounting holes 12 through the first reinforcing ribs 13.

In some embodiments, the outer edge of the annular plate 10 is provided with a flange 14, and the flange 14 extends to one side in the axial direction of the annular plate 10 and covers the outer peripheral surface of the brake.

In the present embodiment, the flange 14 may be a straight edge, and since the flange 14 covers the outer circumferential surface of the stopper, the stopper can be protected.

In the related art, in order to improve the mode of the annular plate 10, the outside of the flange 14 is also required to be hemmed. The annular plate 10 in this embodiment has a high mode after the above-described processing in each example, and therefore, the hemming process is not required and the material consumption is reduced.

In some embodiments, the flange 14 is 90 degrees from the annular plate and the width of the flange 14 is less than or equal to 3mm.

It will be appreciated that the amount of material used may be further reduced by reducing the width of the flange 14 when the stiffness and mode of the annular plate 10 meets design requirements.

In some embodiments, the lowest part of the flange 14 is provided with a notch 15.

It should be noted that, the lowest position of the flange 14 means that, after the annular plate 10 is mounted on the vehicle, the flange 14 is located at the lowest point of the flange 14 in the whole vehicle coordinate, and the flange 14 is disconnected at the notch 15.

Because the dust cover is easy to clamp in foreign matters such as stones and the like in the running process of the vehicle, the stones stay in the dust cover and can strike the dust cover, so that the dust cover is damaged and abnormal sound is generated. In this embodiment, the notch 15 is provided, so that foreign matters such as stones can be quickly removed from the dust cover.

In some embodiments, the annular plate 10 has a cut-out 16 formed after cutting out a partial region, the annular plate 10 being provided with second reinforcing ribs 17 along the cut-out 16.

It should be noted that the lowermost portion of the annular plate 10 may be subjected to a notch treatment because of the need to avoid the lower swing arm ball pin, that is, the lowermost portion of the annular plate 10 is partially cut away. The trim 16 has a very large impact on the first order binding mode of the dust cap. The provision of the second reinforcing ribs 17 makes it possible to increase the rigidity of the annular plate 10 in a targeted manner.

In some embodiments, the annular plate 10 is provided with third ribs 18 in the circumferential direction or fourth ribs 19 in the radial direction.

It will be appreciated that the third 18 and fourth 19 ribs may further enhance the stiffness and mode of the annular plate 10. The annular plate 10 may be provided with third ribs 18 or fourth ribs 19 as required.

In some embodiments, the third stiffener 18 may extend circumferentially and cover the second angular region. The fourth reinforcing bead 19 may extend radially from the first reinforcing bead 13 to the outer edge of the annular plate 10. The third reinforcing rib 18 and the fourth reinforcing rib 19 may have a strip shape, a rectangular shape, or the like, or may have a combination of at least two shapes, and the number of the third reinforcing ribs 18 and the fourth reinforcing ribs 19 may be set as required, which is not limited in this embodiment.

In some embodiments, the annular plate 10 is aluminum magnesium alloy.

It will be appreciated that the aluminium magnesium alloy has a lower density and that the use of this alloy in the manufacture of the annular plate 10 can significantly reduce the weight of the annular plate 10. Meanwhile, by combining the technical schemes in the embodiments, the rigidity and the mode of the annular plate 10 made of the aluminum-magnesium alloy material can be improved, and the problem that the rigidity and the mode of the aluminum-magnesium alloy are low is solved.

An embodiment of the utility model also provides a vehicle comprising a brake dust cover according to the foregoing. The specific structure of the brake dust cover may refer to the foregoing embodiments, and this embodiment is not repeated here.

According to the vehicle, the weight of the dustproof cover is reduced by reducing the material consumption of the dustproof cover of the brake, and meanwhile, the protection and shielding functions of the dustproof cover are reserved, so that the vehicle is easier to realize light weight. Of course, the vehicle may also adopt the technical solutions of the above embodiments, which also have corresponding technical effects.
