Description

Technical Field

[0001] This utility model belongs to the field of automotive brake disc technology, and more specifically, it relates to a layered ventilated brake disc. Background Technology

[0002] Ventilated brake discs are a commonly used type of brake disc. However, ventilated brake discs sometimes fail during use, with the main failure being disc surface penetration failure. When a ventilated brake disc experiences disc surface penetration failure and needs to be replaced, the entire ventilated brake disc often needs to be replaced, which is quite expensive. Summary of the Invention

[0003] The purpose of this invention is to provide a layered ventilated brake disc to overcome the problem that existing ventilated brake discs require complete replacement when a disc surface penetration failure occurs, resulting in high replacement costs.

[0004] This utility model is achieved by the following technical solution: a layered ventilated brake disc, including a main disc surface and a secondary disc surface, wherein multiple connecting ribs are spaced apart along the circumferential direction between the main disc surface and the secondary disc surface, and each connecting rib has a connecting hole. The two ends of the connecting hole pass through the main disc surface and the secondary disc surface respectively. A first countersunk hole is formed at the end of the connecting hole near the main disc surface, and a second countersunk hole is formed at the end of the connecting hole near the secondary disc surface. A rivet is inserted into each connecting hole, and the two ends of the rivet are respectively in the first countersunk hole and the second countersunk hole.

[0005] Furthermore, the connecting rib is fixedly connected to the main disk surface.

[0006] Furthermore, each of the connecting ribs has four connecting holes spaced apart along its length.

[0007] Furthermore, the rivet has a hollow cavity.

[0008] Furthermore, a disc cap is installed on the outer side of the main disc, and a fixing hole is provided on the outer end face of the disc cap.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model designs the main disc and the auxiliary disc as a separate structure. When the main disc or the auxiliary disc fails due to disc penetration, only the disc that is faulty needs to be replaced. Unlike current ventilated brake discs, which require the entire disc to be replaced, this design effectively reduces maintenance costs and allows for the replacement of only the faulty disc.

[0011] 2. The cavity between the main plate and the sub-plate of this utility model forms an intermediate air duct, and the rivet is designed with a hollow cavity. The intermediate air duct and the hollow cavity respectively form heat dissipation air paths and can efficiently remove the heat from the main plate and the sub-plate, thereby giving this utility model a very good heat dissipation capability.

[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0021] A layered ventilated brake disc includes a main disc surface 1 and a secondary disc surface 2. Multiple connecting ribs 3 are spaced apart along the circumferential direction between the main disc surface 1 and the secondary disc surface 2. The cavity between the main disc surface 1 and the secondary disc surface 2 forms an intermediate air duct. A heat dissipation air duct is formed between two adjacent connecting ribs 3. The width of this heat dissipation air duct gradually increases from the inside to the outside. The connecting ribs 3 are fixedly connected to the main disc surface 1.

[0022] Each of the connecting ribs 3 is provided with a connecting hole 4. The two ends of the connecting hole 4 pass through the main disk surface 1 and the secondary disk surface 2 respectively. That is, the connecting hole 4 passes through the main disk surface 1, the connecting rib 3 and the secondary disk surface 2 in sequence.

[0023] The connecting hole 4 has a first countersunk hole 5 at the end near the main plate 1 and a second countersunk hole 6 at the end near the secondary plate 2. A rivet 7 is inserted into each connecting hole 4, with the two ends of the rivet 7 in the first countersunk hole 5 and the second countersunk hole 6, respectively.

[0024] This utility model, through the design of the first countersunk hole 5 and the second countersunk hole 6, facilitates the installation of the rivet 7. After the rivet 7 is installed into the connecting hole 4 and fixed, the two ends of the rivet 7 are respectively in the first countersunk hole 5 and the second countersunk hole 6. This ensures that the two ends of the rivet 7 do not protrude from the braking surfaces of the main disc surface 1 and the secondary disc surface 2. The two ends of the rivet 7 are the rivet head 11 and the riveting head 12, respectively. When connecting, the end of the rivet 7 can first pass through the connecting hole 4 of the main disc surface 1, the connecting hole 4 of the connecting rib 3, and the connecting hole 4 of the secondary disc surface 2. At this time, the rivet head 11 is in the first countersunk hole 5 of the main disc surface 1. Then, the end of the rivet 7 is plastically deformed by a tool to form the riveting head 12, and the riveting head 12 is placed in the second countersunk hole 6.

[0025] This utility model connects the main disc 1 and the auxiliary disc 2 together with multiple rivets 7, thereby forming a split structure between the main disc 1 and the auxiliary disc 2. When the main disc 1 or the auxiliary disc 2 suffers a failure such as disc penetration failure, only the faulty disc needs to be replaced. Unlike current ventilated brake discs, which require the entire disc to be replaced, this effectively reduces maintenance costs and allows for the replacement of only the faulty disc.

[0026] Each of the connecting ribs 3 has four connecting holes 4 spaced apart along its length. By opening multiple connecting holes 4 on the connecting ribs 3, and having both ends of each connecting hole 4 pass through the main disk surface 1 and the secondary disk surface 2 respectively, this invention can make the connection between the main disk surface 1 and the secondary disk surface 2 more secure and improve the heat dissipation effect.

[0027] The rivet 7 is provided with a hollow cavity 8. The cavity between the main plate 1 and the secondary plate 2 forms an intermediate air duct. The rivet 7 is designed with a hollow cavity 8. The intermediate air duct and the hollow cavity 8 respectively form a heat dissipation air path and can efficiently remove the heat from the main plate 1 and the secondary plate 2, thereby giving the present invention a very good heat dissipation capability.

[0028] A disc cap 9 is installed on the outer side of the main disc 1, and a fixing hole 10 is provided on the outer end face of the disc cap 9.
