Description

Technical Field

[0001] This utility model relates to a disc, and more particularly to a wave disc suitable for generating friction to slow down or stop a wheel. Background Technology

[0002] See Figure 1 This describes a conventional brake disc 1 disclosed in Chinese Utility Model Patent Publication No. CN206320209U, comprising two disc plates 11, a plurality of blades 12 disposed between the disc plates 11, and a plurality of cooling channels 13 formed between the blades 12. In this way, during the process of the brake disc 1 being braked and generating heat through friction, the air flowing from the circumference of the brake disc 1 through the cooling channels 13 enhances the heat dissipation effect of the disc plates 11, thereby suppressing thermal deformation caused by the heat during friction.

[0003] However, since the brake disc 1 is a disc, when airflow passes through it, it will deviate from its original flow direction due to the Coanda effect and instead flow along the circumference of the brake disc 1. At this time, the airflow speed will slow down, and a large amount of air will overflow from the circumference of the brake disc 1, resulting in limited heat dissipation. Utility Model Content

[0004] The purpose of this invention is to provide a wave-shaped disc that can significantly improve heat dissipation.

[0005] The wave-shaped disc of this utility model includes a main body and a dividing unit.

[0006] The main body surrounds an axis and is centered on the axis. It includes two spaced-apart disc walls along the axis, a peripheral wall connecting the outer periphery of the disc walls, and multiple air inlets penetrating the peripheral wall. The peripheral wall and the disc walls define an inward-facing annular space and have multiple spaced-apart centrifugal surfaces that gradually move away from the axis, and multiple windward surfaces. Each windward surface connects to two adjacent centrifugal surfaces. The air inlets connect the outside world with the annular space.

[0007] The partition unit includes multiple ribs formed between the disc walls. The ribs divide the annular space to form multiple flow channels. Each flow channel is used to guide the air entering from the corresponding air inlet and discharge it in the direction of the axis.

[0008] The wave disc of this utility model has air inlets distributed on the centrifugal surface and the windward surface.

[0009] The wave disc of this utility model has each centrifugal surface having a proximal end adjacent to the axis and a distal end opposite to the proximal end and away from the axis. Each windward surface connects the proximal end of one of two adjacent centrifugal surfaces and the distal end of the other.

[0010] In the wave disc of this utility model, each of the centrifugal surfaces is a curved surface, a plane, or a combination thereof.

[0011] In the wave disc of this utility model, each of the windward surfaces is a curved surface, a flat surface, or a combination thereof.

[0012] The wave-shaped disc of this utility model further includes multiple heat dissipation groups, each of which has multiple air holes penetrating the disc wall, and the air holes are connected to the corresponding flow channels and the outside.

[0013] In the wave-shaped disc of this invention, the air holes of each heat dissipation group are arranged along a virtual arc, and the air holes at both ends are adjacent to the outer and inner peripheries of the corresponding disc walls.

[0014] The wave-shaped disc of this invention has multiple grooves formed on the outer surface of each disc wall.

[0015] In this invention, each of the grooves extends along a virtual arc, and both ends are adjacent to the outer and inner peripheries of the corresponding disc wall.

[0016] The wave-shaped disc of this utility model further includes a connecting unit, which includes multiple mounting parts, and the mounting parts are connected to the inner periphery of one of the disc walls.

[0017] In this invention, each of the ribs extends along a virtual arc, and the ribs also define multiple channels, each of which connects two adjacent flow channels.

[0018] The beneficial effect of this utility model is that the design of the centrifugal surface and the windward surface increases the airflow into the flow channel, thereby improving the heat dissipation effect. Attached Figure Description

[0033] See Figures 2 to 5 The first embodiment of the wave disc of this utility model includes a body 2, a partition unit 3, and a connecting unit 4.

[0034] The main body 2 surrounds an axis X and is centered on the axis X, including two disk walls 21 spaced apart along the axis X, a peripheral wall 22 connecting the outer periphery of the disk walls 21, and a plurality of air inlets 23 penetrating the peripheral wall 22.

[0035] Each of the disk walls 21 has a plurality of grooves 211 formed on its outer surface. Each groove 211 extends along a virtual first arc L1 and its two ends are adjacent to the outer and inner peripheries of the corresponding disk wall 21.

[0036] The peripheral wall 22 and the disk wall 21 define an inwardly opening annular space 20, and have a plurality of spaced-apart centrifugal surfaces 221 that gradually move away from the axis X, and a plurality of windward surfaces 222. Each centrifugal surface 221 may be a curved surface, a plane, or a combination thereof, having a proximal end 223 adjacent to the axis X, and a distal end 224 opposite to the proximal end 223 and away from the axis X. Each windward surface 222 may be a curved surface, a plane, or a combination thereof, connecting two adjacent centrifugal surfaces 221. More specifically, each windward surface 222 connects the proximal end 223 of one of two adjacent centrifugal surfaces 221 to the distal end 224 of the other.

[0037] In this embodiment, the number of centrifugal surfaces 221 is the same as the number of windward surfaces 222, which are 8 in total. Each centrifugal surface 221 is a curved surface, and each windward surface 222 is also a curved surface.

[0038] The air inlets 23 are distributed on the centrifugal surface 221 and the windward surface 222, connecting the outside world with the annular space 20. Each air inlet 23 can be rectangular, circular, or other shapes. In this embodiment, each air inlet 23 is rectangular.

[0039] The partition unit 3 includes a plurality of ribs 31 formed between the disk walls 21. The ribs 31 divide the annular space 20 to form a plurality of flow channels 30. Each rib 31 extends along a virtual second arc L2. Each flow channel 30 guides air entering from the corresponding air inlet 23 and discharges it in the direction of the axis X. The ribs 31 also define a plurality of channels 310. Each channel 310 connects two adjacent flow channels 30.

[0040] The connecting unit 4 includes a plurality of mounting portions 41. In this embodiment, the mounting portion 41 is connected to the inner periphery of one of the disc walls 21 and is suitable for locking to a wheel (not shown).

[0041] When the wave disc of this invention rotates together with the wheel, it faces the outside air with the corresponding centrifugal surface 221 and the corresponding windward surface 222. This allows the outside air to enter the corresponding flow channel 30 through the corresponding air inlet 23 and flow through the corresponding channel 310 to the adjacent flow channel 30. In this way, the air is rapidly expanded to fill the entire annular space 20, and the airflow rate entering the annular space 20 is greatly increased.

[0042] Finally, the air that enters the annular space 20 will flow from the opening of the annular space 20 toward the axis X, until it is discharged to the outside.

[0043] Therefore, when the body 2 is braked by a caliper (not shown) and generates heat due to friction, the air flowing from the air inlet 23 through the flow channel 30 and the channel 310 in the direction of the axis X can exchange heat with the body 2, thereby improving the heat dissipation effect of the body 2 and suppressing thermal deformation caused by the heat during friction.

[0044] It is worth noting that the groove 211 increases the area of ​​frictional contact with the caliper, thereby increasing friction and achieving a heat-concentrating effect. This allows the caliper to reach its operating temperature (approximately 200°C) more quickly, ensuring stable braking performance.

[0045] See Figure 6 and Figure 7 The second embodiment of the wave-shaped disc of this utility model is largely the same as the first embodiment, also including the body 2, the dividing unit 3, and the connecting unit 4. The difference is:

[0046] The main body 2 also includes multiple heat dissipation assemblies 24. The heat dissipation assemblies 24 are used to replace, for example... Figure 5 The groove 211 is shown. Each of the heat dissipation groups 24 has a plurality of vents 241 penetrating the disk wall 21. The vents 241 connect the corresponding flow channel 30 to the outside. The vents 241 of each heat dissipation group 24 are arranged along the first arc L1, and the vents 241 at both ends are adjacent to the outer and inner peripheries of the corresponding disk wall 21.

[0047] In this way, the air entering the annular space 20 can be discharged to the outside through the opening of the annular space 20 and the air hole 241, thereby accelerating the speed at which the air is discharged from the annular space 20 and further improving the heat dissipation effect.

[0048] It should be noted that the number of centrifugal surfaces 221 and the number of windward surfaces 222 are the same, and not limited to eight. In other variations of this embodiment, the number can also be as follows: Figure 8 As shown, there are 3 respectively, or as... Figure 9 As shown, there are 12 of them. Of course, there could also be 6, 10, or other even numbers.

[0049] Furthermore, the centrifugal surface 221 is not limited to a curved surface; in other variations of this embodiment, it can also be as follows: Figure 10 As shown, it is a plane. Similarly, the windward surface 222 is not limited to a curved surface; in other variations of this embodiment, it can also be as shown... Figure 11 As shown, it is a plane. Of course, the centrifugal surface 221 and the windward surface 222 can also be as follows... Figure 12 As shown, all of them are planes, or as... Figure 13 As shown, this is a combination of a plane and a curved surface.

[0050] Based on the above explanation, the advantages of the aforementioned embodiments can be summarized as follows:

[0051] 1. This utility model can increase the area of ​​the airflow by designing the centrifugal surface 221 and the windward surface 222, thereby significantly increasing the flow rate of air entering the flow channel 30 and thus improving the heat dissipation effect.

[0052] 2. Furthermore, the design of the channel 310 allows the airflow entering the annular space 20 to flow through the corresponding channel 310 to the adjacent flow channel 30. This allows the air to rapidly expand throughout the entire annular space 20, further increasing the airflow rate into the annular space 20 and further enhancing the heat dissipation effect.

[0053] 3. Furthermore, the groove 211 described in the first embodiment can increase the area of ​​frictional contact with the caliper, thereby increasing friction and achieving a heat-concentrating effect. This allows the caliper to reach its operating temperature (approximately 200°C) more quickly, ensuring the stability of braking performance.

[0054] The above description is merely an embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the claims and description of the present utility model shall still fall within the scope of the present utility model.
