Description

Technical Field

[0001] This utility model relates to a drive disc assembly, and more particularly to a heat dissipation and chip removal drive disc assembly for brakes. Background Art

[0002] The drive assembly includes a drive body 1 and a friction disc 4. Currently, the drive body 1 is an annular component with spline teeth 2 on its inner ring surface. An annular friction disc 4 is provided on the entire end face of the drive body 1. (See [link]). Figure 2 When in use, the drive disc body 1 rotates, which in turn causes the friction disc 4 to rotate. The friction of the friction disc 4 drives the rotation of the rotating parts.

[0003] With long-term use, the friction disc 4 is prone to deformation and breakage due to thermal expansion. In addition, the entire friction disc 5 is in close contact with the rotating parts without gaps, which is not conducive to deformation and heat dissipation. At the same time, when the friction disc 4 is partially damaged, the entire friction disc 4 needs to be replaced, resulting in high maintenance costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a brake heat dissipation and chip removal drive disc assembly with novel and unique design, good heat dissipation effect and low maintenance cost.

[0005] The technical solution of the utility model is:

[0006] A heat dissipation and chip removal drive disc assembly for a brake includes a drive disc body. The inner ring surface of the drive disc body is provided with spline teeth to facilitate connection with a spline shaft. The drive disc body is made of metal material. The outer circle of the drive disc body is a non-circular structure, which is composed of spaced rotating blades. All the rotating blades are evenly distributed along the circumference, and each rotating blade is provided with a friction disc.

[0007] Furthermore, the drive disc body and the friction disc are respectively provided with connection holes, and the two are connected together by connectors and connection holes.

[0008] Furthermore, the connecting hole is either a through hole or a countersunk hole.

[0009] The beneficial effects of this utility model are:

[0010] 1. Both the drive disc body and the friction disc of this utility model adopt a non-circular structure. After the friction disc is heated, it can extend slightly to both sides, which effectively prevents deformation and breakage due to compression. In addition, the friction disc is in partial contact with the rotating parts, resulting in good heat dissipation.

[0011] 2. The drive disc body of this utility model has fewer holes than the overall structure, making it easier to rivet and preventing the nuts from loosening. In addition, the gap between adjacent rotating blades serves as a chip removal space, making it less prone to dust accumulation.

[0012] 3. The drive disc body of this utility model is made of metal, which can increase the transmitted torque force and reduce tooth damage. In addition, the friction disc adopts a partial structure, which reduces the cost of replacement when damaged and also reduces the difficulty of replacement.

[0013] 4. This utility model has a novel and unique design, good heat dissipation effect and low maintenance cost, is easy to promote and implement, and has good economic benefits. Attached Figure Description

[0016] Example: See Figure 1 -- Figure 2 In the figure, 1-drive disk body, 2-spline teeth, 3-rotating fan blade, 4-friction disk, 5-connection hole.

[0017] A heat dissipation and chip removal drive disc assembly for a brake includes a drive disc body 1. The inner ring surface of the drive disc body 1 is provided with spline teeth 2 for easy connection with a spline shaft to transmit rotational power. The number and size of the spline teeth 2 are determined according to actual use and are not detailed. The drive disc body 1 is made of metal material and has good rigidity to prevent damage to the spline teeth 2. The outer circle of the drive disc body 1 is a non-circular structure, which is composed of spaced rotating blades 3 (three rotating blades 3 are shown in the figure. Four or six blades or other different numbers can be set as needed, which are not listed one by one). All rotating blades 3 are evenly distributed along the circumference, and each rotating blade 3 is provided with a friction disc 4.

[0018] Preferred solution: The drive disc body 1 and the friction disc 4 are each provided with a connecting hole 5, and the two are connected together by a connector and the connecting hole 5, allowing for disassembly and assembly. The connecting hole 5 on the friction disc 4 can be a countersunk hole, while the connecting hole on the drive disc body 1 can be a through hole or a countersunk hole.

[0019] In use, the drive disk body 1 is mounted on the spline shaft. When the drive disk body 1 rotates, the friction disk 4 rotates accordingly. The friction of the friction disk 4 drives the rotation of the rotating parts, thus completing the drive operation.

[0020] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications made based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
