Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically to a split-type high-life brake disc structure. Background Technology

[0002] Brake discs are a crucial component of a vehicle's braking system. Their primary function is to convert the pressure applied by the brake calipers into friction, effectively slowing or stopping the vehicle's movement. However, most brake discs on the market today have a relatively simple design, and defects in their materials and structure result in insufficient cooling rates. Under prolonged driving or frequent braking conditions, brake discs easily become overheated. The heat cannot dissipate in time, leading to reduced braking effectiveness and, in severe cases, brake failure, posing a significant risk to the driver's life. Utility Model Content

[0008] An annular air duct is arranged along the circumference of the brake disc body to connect the first heat dissipation slot and the second heat dissipation slot.

[0009] The annular air duct passes through the air guide surface.

[0010] The cross-sectional area of ​​the second heat dissipation groove is larger than that of the first heat dissipation groove.

[0011] The mounting disc and the brake disc are connected together by rivets.

[0012] The brake disc body is provided with a flange, and the flange is provided with mounting holes for rivet installation.

[0013] The mounting plate includes a circumferential wall located on the outside of the flange.

Attached Figure Description

[0018] Figure 1 This is a structural schematic diagram of one embodiment of the present invention.

[0019] Figure 2 for Figure 1 Schematic diagram of cross-section at point AA. Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings. A split-type high-life brake disc structure includes a mounting disc body 1 and a brake disc body 2, and also includes alternating first heat dissipation grooves 3 and second heat dissipation grooves 4. The first heat dissipation groove extends radially along the brake disc body and penetrates the brake disc body; the second heat dissipation groove is provided on the brake disc body, and includes an air inlet 41 on the circumferential outer wall of the brake disc body, and an arc-shaped air guide surface 42 on the inner wall of the second heat dissipation groove; an annular air duct 5 is arranged circumferentially along the brake disc body and is used to connect the first heat dissipation groove and the second heat dissipation groove. Figure 1 The small and medium arrows indicate the direction of airflow, while the curved arrows indicate the direction of rotation. After entering, the airflow will come into contact with the air guide surface and then travel through the annular air duct to other heat dissipation slots. The first heat dissipation slot is a through-type design with a small area, while the second heat dissipation slot is a recessed design, which improves heat dissipation performance while ensuring rigidity.

[0021] In this embodiment, as shown in the figure, the annular air duct passes through the air guide surface.

[0022] In this embodiment, as shown in the figure, the cross-sectional area of ​​the second heat sink is larger than that of the first heat sink.

[0023] In this embodiment, as shown in the figure, the mounting disc body and the brake disc body are connected together by rivets.

[0024] In this embodiment, as shown in the figure, the brake disc body is provided with a flange 21, and the flange is provided with mounting holes 211 for riveting. The installation is secure via riveting.

[0025] In this embodiment, as shown in the figure, the mounting plate includes a circumferential wall 7, which is located on the outside of the flange.

[0026] In this embodiment, as shown in the figure, the height of the longitudinal section of the second heat dissipation groove is 1 / 4 to 1 / 3 of the thickness of the brake disc body. This ensures rigidity.

[0027] In this embodiment, as shown in the figure, the mounting plate is made of aluminum alloy.

[0028] In this embodiment, as shown in the figure, the brake disc body is made of cast iron. Traditional one-piece brake discs, due to the use of a single material, are not suitable for different manufacturing processes. This results in vibrations generated during braking not being effectively absorbed, leading to low overall strength and potential brake disc breakage during driving. Our product, through a structural design connecting aluminum alloy and cast iron, allows for a composite process of carburizing and sandblasting on the surface. This helps reduce vibration transmission, significantly increases brake disc strength and surface roughness, resulting in superior braking performance and higher strength, making it less prone to breakage.
