Technical Field
[0001] The utility model belongs to the technical field of automobile brake disc dust covers, and particularly relates to an automobile brake disc dust cover. Background Technique
[0002] An automobile brake disc dust cover is a component installed on a vehicle braking system, usually made of metal or plastic. Its main function is to prevent dust, mud and other sundries from entering the brake disc and the inside of the brake, so as to protect the braking system from pollution and damage. The brake disc dust cover also plays a role in heat insulation to prevent the high temperature generated during the use of the brake disc from being transmitted to the brake system, resulting in safety accidents.
[0003] The existing automobile brake disc dust cover is a thin plate structure, which has a low modal frequency during use, is easy to cause vibration and even failure, and has low structural strength. At the same time, although the partition design plays a role in heat insulation, it is also easy to cause poor heat dissipation of the brake disc. Content of the Utility Model
[0004] In order to solve the technical problem that although the existing partition design of the automobile brake disc plays a role in heat insulation, it is also easy to cause poor heat dissipation of the brake disc, the utility model provides the following technical solutions:
[0005] The utility model relates to an automobile brake disc dust cover, which includes an inner cover and an outer cover. An outward flanging is integrally stamped between the inner cover and the outer cover. The outer cover is provided with a first reinforcing rib and a second reinforcing rib. A plurality of heat dissipation air holes are equidistantly and annularly opened on the outer cover. A plurality of convex ribs are integrally formed on the outer cover and the convex ribs are located outside the heat dissipation air holes.
[0006] As a preferred technical solution of the utility model, a shaft hole is opened at the center of the inner cover, a plurality of mounting holes are equidistantly and annularly opened on the inner cover, and a positioning hole is opened on the inner cover.
[0007] As a preferred technical solution of the utility model, an inward flanging is provided at the outer edge of the inner cover.
[0008] As a preferred technical solution of the utility model, the outer cover is in a semi-circular ring shape and an opening is opened on the outer cover.
[0009] As a preferred technical solution of the utility model, the first reinforcing rib is in a semi-circular ring shape and is concentric with the outer cover.
[0010] As a preferred technical solution of the utility model, a plurality of second reinforcing ribs are provided and are equidistantly arranged in a circumferential array with the center of the inner cover as the axis.
[0011] As a preferred technical solution of the present utility model, both the inner cover and the outer cover are integrally stamped from aluminum alloy, and the surfaces of the inner cover and the outer cover are both treated with frosting.
[0012] The beneficial effects achieved by the present utility model are as follows:
[0013] The overall modal frequency is improved through the concentric distributed design of the first reinforcing rib and the second reinforcing rib, and the overall strength is also improved. The use of aluminum alloy material design reduces the weight, making it more lightweight, and the frosting treatment on the surface can adsorb dust.
[0014] During the driving of the vehicle, since the surfaces of the inner cover and the outer cover are treated with frosting to adsorb dust, at the same time, the rotation of the wheels forms an air vortex, and the vortex air drives the heat and floating dust on the brake disc and discharges them through the heat dissipation holes, and the heat will not be conducted to the braking system located inside the inner cover through the guiding of the convex ribs.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment: As Figures 1-3As shown in the figure, an automotive brake disc dust cover includes an inner cover 1 and an outer cover 2. There is an outward-turned edge 3 integrally stamped between the inner cover 1 and the outer cover 2. During use, the design of the outward-turned edge 3 enhances the overall strength on the one hand and controls the distance between the outer cover 2 and the brake disc on the other hand. The outer cover 2 is provided with a first reinforcing rib 201 and a second reinforcing rib 202. A plurality of heat dissipation air holes 203 are equidistantly and annularly arranged on the outer cover 2. A plurality of convex ribs 204 are integrally formed on the outer cover 2 and the convex ribs 204 are located outside the heat dissipation air holes 203. During use, when the vehicle is moving, the rotation of the wheels forms an air vortex. The swirling air drives the heat on the brake disc and discharges it through the heat dissipation air holes 203, and the heat is guided by the convex ribs 204 and will not be conducted to the braking system located inside the inner cover 1.
[0022] A shaft hole 101 is provided at the center of the circle of the inner cover 1. A plurality of mounting holes 102 are equidistantly and annularly arranged on the inner cover 1. A positioning hole 103 is provided on the inner cover 1. During use, the inner cover 1 is sleeved and installed through the shaft hole 101, and the inner cover 1 is fixed by inserting bolts through the mounting holes 102, and positioning is performed through the positioning hole 103 during installation to prevent installation deviation.
[0023] An inward-turned edge 104 is provided at the outer edge of the inner cover 1. During use, the design of the inward-turned edge 104 can prevent dust from falling into the automotive axle rod rubber sleeve.
[0024] The outer cover 2 is in a semi-circular ring shape and an opening 205 is provided on the outer cover 2. During use, the design of the opening 205 reserves an installation space for the braking system.
[0025] The first reinforcing rib 201 is in a semi-circular ring shape and is concentric with the outer cover 2. There are multiple second reinforcing ribs 202 and they are equidistantly and circumferentially arranged in an array with the center of the circle of the inner cover 1 as the axis. During use, the overall modal frequency is enhanced through the concentric distributed design of the first reinforcing rib 201 and the second reinforcing ribs 202.
[0026] Both the inner cover 1 and the outer cover 2 are made of aluminum alloy by integral stamping. The surfaces of both the inner cover 1 and the outer cover 2 are treated with frosting. During use, the design of aluminum alloy material reduces the weight and enhances the strength, and the frosting treatment on the surface can adsorb dust and prevent dust from falling into the gaps of the braking system for easy cleaning later.
[0027] Specifically, when the utility model is in use, the inner cover 1 is sleeved and installed through the shaft hole 101, and the inner cover 1 is fixed by inserting bolts through the installation holes 102. During the installation process, positioning is performed through the positioning holes 103 to prevent deviation during installation. During the driving of the vehicle, the inner cover 1 and the outer cover 2 are used for dust prevention and heat insulation. Since the surfaces of the inner cover 1 and the outer cover 2 are treated with frosting, they can adsorb dust. At the same time, when the wheel rotates, an air vortex is formed, and the swirling air drives the heat and floating dust on the brake disc and discharges them through the heat dissipation air holes 203. Moreover, the convex ribs 204 guide the heat so that it will not be conducted to the braking system located inside the inner cover 1.
