Description

Technical Field

[0001] This utility model relates to the field of automotive brake technology, specifically to a connection structure between a brake disc and a brake head. Background Technology

[0002] To reduce chassis weight and improve handling, racing cars and high-performance road bikes often use two-piece brake discs with separate bearings. With breakthroughs in industrial technology, one type of brake disc—the carbon ceramic disc—has seen increased use due to its superior performance and lower price. Carbon ceramic discs are lightweight, wear-resistant, and highly durable. Traditional two-piece bearings are directly connected to the brake disc using bolts. The bearing is directly attached to the brake disc, with a bolt passing through the bearing and tightened with a nut at the rear. This method allows a significant amount of heat from the brake disc to be transferred to the bearing during braking, causing it to overheat and deform. Utility Model Content

[0003] The purpose of this utility model is to provide a connection structure between the connector and the brake disc, which separates the connector from the brake disc, reduces the heat transferred from the brake disc to the connector during braking, avoids high-temperature deformation of the connector, and reduces replacement costs due to the separate design of the connecting parts.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0005] A connection structure for a coupling and a brake disc includes a coupling and a brake disc arranged coaxially. The circumferential sidewall of the coupling is provided with multiple mounting grooves, and the surface of the brake disc is provided with mounting holes corresponding to the mounting grooves. The structure also includes a connection structure, which includes a locking member and a connecting member. The connecting member includes a split first connecting part and a second connecting part. One end of the first connecting part is adapted to be inserted into one side of the mounting groove, and one end of the second connecting part is adapted to be inserted into the other side of the mounting groove and engaged with the first connecting part. The other end of the second connecting part is inserted into the mounting hole. The second connecting part is provided with a partition plate that separates the coupling and the brake disc. The locking member passes through the first connecting part and the second connecting part in sequence to connect the coupling and the brake disc.

[0006] In this design, the connector adopts a split structure, which eliminates the need to replace the entire connector when it is replaced later. Only the damaged part needs to be replaced, saving replacement costs. The connector is inserted into the mounting slot and mounting hole to connect and secure the head to the brake disc. An isolation plate is provided on the second connection part to separate the head and the brake disc, creating a gap between them. When braking, only a small portion of the heat on the brake disc is transferred to the head through the isolation plate, while most of the heat is transferred to the air through the gap between them. This avoids the risk of the head deforming due to excessive temperature during braking, extends the service life of the head, and ensures the normal operation of the braking system.

[0007] Optionally, the end face of the first connecting part opposite to the mating head is provided with a first locking block adapted to the assembly groove. The first locking block protrudes in the direction of the mating head, and the bottom surface of the first locking block is provided with a slot. The end face of the second connecting part opposite to the mating head is provided with a second locking block adapted to the assembly groove. The second locking block protrudes in the direction of the mating head, and the end face of the second locking block facing the first locking block is provided with a plug that can be inserted into the slot.

[0008] Optionally, the isolation plate is disposed on both sides of the lower end of the second card block, and the length of the isolation plate is greater than the width of the assembly groove.

[0009] Optionally, the lower end of the isolation plate is provided with a connecting rod that is adapted to the inner diameter of the assembly hole, and the connecting rod can be inserted into the assembly hole.

[0010] Optionally, the dimension of the end face opposite the first connecting part and the mating head is larger than the dimension of the assembly groove.

[0011] Optionally, the assembly groove is a U-shaped groove with the opening facing outward and located radially on the mating head.

[0012] Optionally, the insert block and the second locking block are integrally formed, the second locking block and the isolation plate are integrally formed, the isolation plate and the connecting rod are integrally formed, and the top surface of the insert block is provided with a through hole that allows the locking element to be inserted. The through hole extends downward and passes through the first locking block, the isolation plate and the connecting rod.

[0013] Optionally, the slot is a stepped slot, which restricts the upward displacement of the insert block.

[0014] Optionally, the top surface of the first connecting part is provided with a countersunk hole that communicates with the slot, and the countersunk hole allows the locking element to pass through.

[0015] Optionally, the locking component includes a screw and a nut, with one end of the screw passing through the first connecting part and the second connecting part in sequence and then threadedly connected to the nut.

[0016] The beneficial effects of this utility model are:

[0017] In this invention, the connector adopts a split structure, which eliminates the need to replace the entire connector when it is replaced later. Only the damaged part needs to be replaced, saving replacement costs. The connector is inserted into the assembly slot and assembly hole to connect and secure the head to the brake disc. An isolation plate is provided on the second connection part to separate the head and the brake disc, creating a gap between them. When braking, only a small portion of the heat on the brake disc is transferred to the head through the isolation plate, while most of the heat is transferred to the air through the gap between them. This avoids the risk of the head deforming due to excessive temperature during braking, extends the service life of the head, and ensures the normal operation of the braking system.

[0027] Example

[0028] A connection structure for a coupling and a brake disc includes a coupling 2 and a brake disc 1 coaxially arranged. The circumferential sidewall of the coupling 2 is provided with a plurality of mounting grooves 3. The surface of the brake disc 1 is provided with mounting holes 4 corresponding to the mounting grooves 3. The structure also includes a connection structure, which includes a locking member and a connecting member. The connecting member includes a split first connecting part 6 and a second connecting part 7. One end of the first connecting part 6 is adapted to be inserted into one side of the mounting groove 3, and one end of the second connecting part 7 is adapted to be inserted into the other side of the mounting groove 3 and is engaged with the first connecting part 6. The other end of the second connecting part 7 is inserted into the mounting hole 4. The second connecting part 7 is provided with a partition plate 8 that separates the coupling 2 from the brake disc 1. The locking member passes through the first connecting part 6 and the second connecting part 7 in sequence to connect the coupling 2 and the brake disc 1.

[0029] In this embodiment, as Figures 1-5 As shown, both the head 2 and the brake disc 1 are disc-shaped. The mounting grooves 3 are evenly distributed on the circumferential sidewall of the head 2, and the mounting holes 4 are evenly distributed in a ring on the side of the brake disc 1. After the mounting holes 4 are aligned with the mounting grooves 3, the connector passes through the head 2 and the brake disc 1 to assemble them together. Then, the locking member passes through the connector to lock the head 2 and the brake disc 1. The connector adopts a split structure, so that when the connector is replaced later, it is not necessary to replace the whole connector. Only the damaged part is replaced directly, saving replacement costs. The connector is inserted into the mounting grooves 3 and mounting holes 4 to connect and secure the head 2 and the brake disc 1. An isolation plate 8 is provided on the second connecting part 7. The isolation plate 8 separates the head 2 and the brake disc 1, creating a gap between them. When braking, only a small part of the heat on the brake disc 1 is transferred to the head 2 through the isolation plate 8. Most of the heat is transferred to the air through the gap between them. Therefore, the risk of the head 2 deforming due to excessive temperature during braking is avoided, the service life of the head 2 is extended, and the normal operation of the braking system is ensured.

[0030] Furthermore, the end face of the first connecting part 6 opposite to the head 2 is provided with a first locking block 11 that is adapted to the assembly groove 3. The first locking block 11 protrudes towards the head 2, and the bottom surface of the first locking block 11 is provided with a slot 15. The end face of the second connecting part 7 opposite to the head 2 is provided with a second locking block 12 that is adapted to the assembly groove 3. The second locking block 12 protrudes towards the head 2, and the end face of the second locking block 12 facing the first locking block 11 is provided with an insert 16 that can be inserted into the slot 15.

[0031] Specifically, such as Figure 3As shown, the first locking block 11 is a square with a downward protrusion. The lower end face of the first locking block 11 is provided with a slot 15. The first locking block 11 is inserted into one side of the assembly groove 3. The assembly groove 3 can restrict the rotation of the first locking block 11, thereby restricting the relative rotation between the first connecting part 6 and the assembly groove 3. The upper end of the second locking block 12 is provided with a second locking block 12. The second locking block 12 is inserted into the other side of the assembly groove 3. The upper end of the second locking block 12 is provided with an insert 16. After the second locking block 12 is inserted into the assembly groove 3, the insert 16 is also inserted into the slot 15. The assembly groove 3 simultaneously restricts the rotation of the second locking block 12, thereby restricting the relative rotation between the second connecting part 7 and the assembly groove 3. The first locking block 11, the second locking block 12 and the assembly groove 3 fit together, making the installation margin smaller and the concentricity of the assembly of the head 2 and the brake disc 1 higher.

[0032] Furthermore, the isolation plate 8 is disposed on both sides of the lower end of the second card block 12, and the length of the isolation plate 8 is greater than the width of the assembly groove 3.

[0033] Specifically, the length of the isolation plate 8 is greater than the width of the assembly groove 3, so that the isolation plate 8 cannot pass through the assembly groove 3, which can better separate the head 2 and the brake disc 1. The isolation plate 8 and the assembly groove 3 are arranged in a cross shape.

[0034] Furthermore, the lower end of the isolation plate 8 is provided with a connecting rod 14 that is adapted to the inner diameter of the assembly hole 4, and the connecting rod 14 can be inserted into the assembly hole 4.

[0035] Furthermore, the end face dimension of the first connecting part 6 opposite to the mating head 2 is larger than the dimension of the assembly groove 3.

[0036] Specifically, the end face size of the first connecting part 6 opposite to the head 2 is larger than the size of the assembly groove 3, so that only the first locking block 11 in the first connecting part 6 can pass through the assembly groove 3, and the two sides of the first connecting part 6 are flat surfaces.

[0037] Furthermore, the assembly groove 3 is a U-shaped groove with its opening facing outward and located radially on the mating head 2.

[0038] Furthermore, the insert block 16 is integrally formed with the second locking block 12, the second locking block 12 is integrally formed with the isolation plate 8, the isolation plate 8 is integrally formed with the connecting rod 14, and the top surface of the insert block 16 is provided with a through hole 13 that allows the locking element to be inserted. The through hole 13 extends downward through the first locking block 11, the isolation plate 8, and the connecting rod 14.

[0039] Furthermore, the slot 15 is a stepped slot, which restricts the upward displacement of the insert block 16.

[0040] Furthermore, the top surface of the first connecting part 6 is provided with a countersunk hole 10 that communicates with the slot 15, and the countersunk hole 10 allows the locking member to pass through.

[0041] Furthermore, the locking component includes a screw 5 and a nut 9. One end of the screw 5 passes through the first connecting part 6 and the second connecting part 7 in sequence and is then threadedly connected to the nut 9.

[0042] The assembly principle of this utility model is as follows: First, place the head 2 on one side of the brake disc 1, which is the left side of the brake disc 1 in this embodiment. Align the assembly groove 3 with the assembly hole 4. Place the second connecting part 7 between the head 2 and the brake disc 1. The second locking block 12 in the second connecting part is inserted into one side of the assembly groove 3. The connecting rod 14 is inserted into the assembly hole 4. Then, the first locking block 11 in the first connecting part 6 is inserted into the other side of the assembly groove 3, and the insert block 16 on the second locking block 12 is inserted into the slot 15 of the first locking block 11. Finally, the right end of the screw 5 is inserted into the countersunk hole 10 on the first connecting part 6, the insertion hole on the first locking block 11, and the through hole 13 on the insert block 16 in sequence, and passes through the through hole 13 in the second locking block 12, the isolation plate 8, and the connecting rod 14. The right end of the screw 5 is finally located outside the connecting rod 14. Then, tighten the nut 9 to lock the head 2 and the brake disc 1. The assembly order of the first connecting part 6 and the second connecting part 7 is not important.

[0043] 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, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
