[0038] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0039] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or can have a middle element present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or can have a middle element present.

[0040] It should also be noted that the terms such as left, right, up, down, etc. in the embodiments of the present application are only relative concepts or are with reference to the normal use state of the product, and should not be considered as limiting.

[0041] Referring to Figure 1 and Figure 2 , the brake mounting plate provided by the embodiment comprises a plate body 1, a notch 2 is formed on the outer periphery of the plate body 1, a protruding portion 12 is formed on a first surface 11 of the plate body 1, a transition portion 13 is formed between the protruding portion 12 and the first surface 11 and is arranged obliquely, and the shape of the protruding portion 12 is a circular truncated cone. An inner recess 15 is formed at a second surface 14 opposite to the first surface 11, a first through hole 16 is formed on the upper surface of the protruding portion 12, the axis of the first through hole 16 coincides with the axis of the protruding portion 12, and the axis of the protruding portion 12 coincides with the axis of the plate body 1. A mounting hole 17 is formed on the outer side of the first through hole 16, and a second through hole 18 is formed on the outer side of the mounting hole 17. The shape of the plate body 1 is circular, the central angle corresponding to the notch 2 is about 120°, and the central angle corresponding to the plate body 1 is about 240°.

[0042] Referring to Figure 1 and Figure 2 , the number of mounting holes 17 is more than one, and the mounting holes 17 are arranged along the circumference of the first through hole 16. In the embodiment, the number of mounting holes 17 is four, and the four mounting holes 17 are symmetrically arranged at the two ends of the first through hole 16. In this way, the connection effect between the brake mounting plate and the hub bearing can be ensured. The number of second through holes 18 is more than one, and the second through holes 18 are distributed along the circumference of the upper surface. In the embodiment, the number of second through holes 18 is multiple, and the multiple second through holes 18 are uniformly distributed along the circumference of the upper surface. Because a large amount of heat is generated by the brake disc during driving of the automobile, the brake disc needs to be cooled in time. The second through hole 18 is used for circulation of external gas, so that the heat of the brake disc can be quickly taken away. The opening of multiple second through holes 18 can improve the heat dissipation efficiency of the brake disc, so that the temperature of the brake disc does not rise rapidly, thereby ensuring the effectiveness of the work of the brake disc.

[0043] Referring to Figure 2 The recess 19 is formed on the second surface 14, and the recess 19 is arranged along the circumference of the second surface 14 and is arranged at the connection between the inner recess 15 and the second surface 14. The number of the recess 19 is more than one, and the recess 19 is distributed along the circumference of the second surface 14. In the embodiment, the number of the recess 19 is two, and the two recesses are evenly distributed along the circumference of the second surface 14. The recess 19 is formed on the back surface of the mounting plate, which can increase the heat dissipation area of the mounting plate. During the driving of the vehicle, the recess 19 can be used to disturb the flow of air, thereby increasing the heat dissipation efficiency of the mounting plate. The recess 19 is mainly used for the heat dissipation of the brake mounting plate itself. The number of the recess 19 is not limited to two, and can be three or more, which can be adjusted according to the actual design requirements.

[0044] Referring to Figure 3 The transition part 13 is formed between the first surface 11 and the protruding part 12, and the shape of the protruding part 12 is a circular truncated cone, and the waist part of the circular truncated cone forms the transition part 13. The transition part 13 is a support part arranged obliquely, which can increase the thickness of the plate body 1, thereby enhancing the strength of the plate body 1, so that the plate body 1 will not be easily damaged due to the corrosion of foreign matters splashed from the outside, and the protection of the brake assembly can be ensured, and the effectiveness of the brake assembly can be ensured. The first through hole 16 is used for installing the hub bearing, and the mounting hole 17 is used for installing the knuckle. In the embodiment, the surface of the transition part 13 is a plane, but the transition part 13 is not limited to the plane in the embodiment, and the transition part 13 can be an arc surface according to the actual design requirements.

[0045] Referring to Figure 1 The second through hole 18 is formed at the connection between the upper surface and the transition part 13. It should be noted that the second through hole 18 can also be completely formed on the upper surface, and the second through hole 18 is distributed along the circumference of the upper surface. Another preferred scheme is that the second through hole 18 is formed on the transition part 13, and the second through hole 18 is distributed along the circumference of the transition part 13. The most preferred scheme is that the second through hole 18 is formed at the connection between the upper surface and the transition part 13, and the second through hole 18 is formed at this position, which can maximize the heat dissipation of the heat inside the brake assembly.

[0046] In the embodiment, the brake mounting plate further comprises mounting ears 3 integrally formed on the outer periphery of the plate body 1, and the number of the mounting ears 3 is more than one. In the embodiment, the number of the mounting ears 3 is three, and the three mounting ears 3 are evenly distributed along the outer periphery of the plate body. The central angle formed between two adjacent mounting ears 3 is about 120°, and a mounting block 31 is arranged on the mounting ear 3, and the mounting block 31 is mounted on the mounting ear 3 by means of a countersunk screw 32. The mounting ear 3 is arranged on the brake mounting plate to provide a mounting position for the functional parts and decorative parts of the hub inner ring, and meanwhile, the number of the mounting ears 3 can be increased or decreased according to the mounting requirements of the mounting parts, and the position of the mounting ear 3 can be adjusted according to the mounting requirements of the mounting parts. Figure 1 The above is only a preferred scheme.

[0047] Referring to Figure 4 and Figure 5 , the brake assembly provided by the embodiment further comprises a steering knuckle 4, a brake caliper 5, a brake disc 6 and a hub bearing 7. The reserved notch 2 on the plate body 1 provides a mounting position for the brake caliper 5, and the brake caliper 5 is mounted on the notch 2. A first fastening bolt 8 is arranged on the mounting hole 17. In the process of assembling the brake assembly, first, the brake mounting plate is assembled on the hub bearing 7, in this process, the hub bearing 7 passes through the first through hole 16, then the mounting hole 17 on the brake mounting plate is aligned with the mounting hole (not shown in the figure) on the hub bearing, then the steering knuckle 4 is assembled on the second surface 14 of the brake mounting plate, and then the first fastening bolt 8 is used to pass through the mounting holes (not shown in the figure) on the steering knuckle 4, the plate body 1 and the hub bearing 7 in sequence to assemble them together. The brake disc 6 is mounted on the outer wall of the hub bearing 7, and the brake disc 6 is fixed on the hub bearing 7 by means of a second fastening bolt 9. A gap 10 is left between the brake disc 6 and the plate body 1 for heat dissipation of the brake disc 6. The second through hole 18 is arranged near the hub bearing 7, which can effectively reduce the heat generated by the hub bearing 7 during the driving of the vehicle from being transferred to the brake disc 6, reduce the influence of temperature on the brake disc 6, and ensure the effectiveness of the brake disc 6. The temperature generated by the rotation of the hub bearing 7 during the driving of the vehicle can be effectively reduced by the second through hole 18 to accelerate the air circulation and well protect the working environment of the hub bearing 7.

[0048] Referring to Figure 5The shape of the transition part 13 is a bevel, which can ensure that the gap 10 between the brake disc 6 and the plate body 1 forms a streamlined space, so that the airflow can flow smoothly in the gap 10, accelerate the airflow velocity, and ensure that the heat generated at the hub bearing 7 can be dissipated in time. If the shape of the transition part is rectangular, the gap 10 between the brake disc 6 and the plate body 1 will be very small, which will block the flow of gas and be not conducive to the heat dissipation of the hub bearing 7. A cavity 61 is formed in the brake disc 6, and the cavity 61, the gap 10 and the second through hole 18 form an air path. The airflow passes through the gap 10 from the cavity 61 and then is discharged through the second through hole 18, and the heat of the hub bearing 7 and the brake disc 6 is discharged in the process of discharging the airflow.

[0051] (2) Strength: in order to meet the strength required for installing functional parts and decorative parts in the hub inner ring, the brake mounting plate increases the thickness of the plate body to increase its own strength, and a transition part is designed to increase the overall stiffness, so that the brake mounting plate meets the required strength for installing other functional parts and decorative parts;

[0052] (3) Light weight: in order to increase the strength required for installing functional parts and decorative parts in the hub inner ring, the brake mounting plate increases the thickness of the structural part, and the thickening of the thickness increases the overall weight of the brake mounting plate. In order to reduce the overall weight of the brake mounting plate while ensuring that the brake mounting plate meets the necessary strength, a groove is designed on the brake mounting plate to reduce the weight of the plate body itself. The second through hole is designed on the brake mounting plate, which can also reduce the weight of the brake mounting plate after having the ventilation effect;

[0053] (4) Safety: the brake mounting plate increases the thickness of the structural part, and a reinforcing diagonal brace is designed to increase the overall stiffness, which enhances the anti-splashing damage ability of the brake mounting plate and better protects other functional structural parts;

[0054] (5) Stability: the brake mounting plate increases the thickness of the structural part, which effectively increases the anti-shock property of the brake mounting plate and reduces the abnormal noise caused by resonance during vehicle driving.

[0055] It should be noted that the brake assembly provided in the embodiment is used in a vehicle, the hub bearing 7 in the brake assembly is connected with a wheel of the vehicle. The knuckle 4 in the brake assembly is connected with a steering system in the vehicle, and is used for steering during driving of the vehicle.
