[0036] See also Figures 1 to 3 The utility model provides a lightweight composite brake disc, comprising: a brake disc body 1, two wear-resistant bodies 2 and at least two clamping parts 3, the two wear-resistant bodies 2 are respectively arranged on both sides of the brake disc body 1, and a filling gap 4 is formed between the wear-resistant bodies 2 and the outer wall of the brake disc body 1, the filling gap 4 is used to fill an adhesive 5, the clamping part 3 is built into the filling gap 4, the clamping part 3 is connected to any one of the brake disc body 1 and the wear-resistant body 2, and can be clamped with the other of the brake disc body 1 and the wear-resistant body 2, so as to limit the wear-resistant body 2 from sliding relative to the brake disc body 1.

[0037] In the present device, two wear-resistant bodies 2 are respectively arranged on both sides of the brake disc body 1, and are respectively enclosed with the outer walls on both sides of the brake disc body 1 to form a filling gap 4, and the filling gap 4 is filled with an adhesive. At least two clamping parts 3 are respectively arranged on both sides of the brake disc body 1 and are built into the filling gap 4. The clamping part 3 is connected to any one of the brake disc body 1 and the wear-resistant body 2, and can be matched and clamped with the other one of the brake disc body 1 and the wear-resistant body 2, so as to limit the wear-resistant body 2 from sliding relative to the brake disc body 1.

[0038] Compared with the prior art, the sliding of the wear-resistant body 2 relative to the brake disc body 1 is limited by the clamping connection between the clamping portion 3 and the brake disc body 1 and the wear-resistant body 2. At the same time, the wear-resistant body 2 and the brake disc body 1 are bonded by an adhesive to enhance the connection strength between the two. This can solve the technical problem in the prior art that the connection strength between the brake disc body and the wear-resistant layer is not high because the brake disc body and the wear-resistant layer are manufactured and formed by a casting process.

[0039] Furthermore, in the present device, the brake disc body 1 is connected to two wear-resistant bodies 2 to form a brake disc structure for an automobile. The brake disc body 1 is the main body of the brake disc, and the wear-resistant body 2 is a wear-resistant plate. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0040] As an implementation method, Figure 1 , Figure 3 As shown, at least one clamping groove is respectively formed on both sides of the brake disc body 1, and at least two clamping parts 3 are respectively connected to the two wear-resistant bodies 2 and can be clamped in the clamping groove.

[0041] Specifically, the clamping portion 3 in the device is connected to the wear-resistant body 2 and is engaged with the clamping groove on the brake disc body 1, so as to limit the wear-resistant body 2 from sliding relative to the brake disc body 1 or rotating around its axis.

[0042] Furthermore, in the device, the wear-resistant body 2 and the plurality of clamping parts 3 are integrally formed and processed.

[0043] As a preferred implementation method, Figure 4 As shown, the clamping portion 3 is in a strip shape, is arranged along the radial direction of the wear-resistant body 2, and is connected to the wear-resistant body 2.

[0044] The strip-shaped clamping portion 3 can effectively enhance the limiting effect and increase the connection strength between the wear-resistant body 2 and the brake disc body 1 .

[0045] As a preferred implementation method, Figure 5 As shown, the cross section of the clamping portion 3 is trapezoidal, and the cross section area of ​​the clamping portion 3 gradually decreases in the direction away from the wear-resistant body 2 , and the clamping groove is arranged in conjunction with the clamping portion 3 .

[0046] The cross-section is a trapezoidal structure, which can facilitate installation and assembly and improve assembly accuracy and efficiency.

[0047] As an implementation method, Figure 3 As shown in the figure, there are multiple clamping grooves in the brake disc body 1, and the multiple clamping grooves are arranged at intervals along the circumferential direction of the brake disc body 1. The clamping parts 3 are arranged one by one corresponding to the clamping grooves and are clamped in cooperation.

[0048] The plurality of clamping portions 3 spaced apart along the circumferential direction of the brake disc body 1 can enhance the limiting effect and increase the connection strength between the wear-resistant body 2 and the brake disc body 1 .

[0049] Specifically, the number of the clamping parts 3 in the device is twelve.

[0050] like Figure 1 , Figure 3 As shown, protrusions 11 are formed on both sides of the brake disc body 1, and a recessed portion 21 is formed on the wear-resistant body 2 relative to the protrusions 11. The recessed portion 21 is engaged with the protrusions 11 to limit the radial sliding of the wear-resistant body 2 relative to the brake disc body 1.

[0051] The engagement between the protrusion 11 and the depression 21 can further enhance the effect of limiting the rotation of the brake disc body 1 and the wear-resistant body 2 .

[0052] As an implementation mode, the recessed portion 21 penetrates through the wear-resistant body 2 .

[0053] By setting up a through structure, the dead weight can be effectively reduced, which is beneficial to the lightweight design of the brake disc.

[0054] As another embodiment, the raised portion 11 is provided with a through groove 12 and a plurality of connecting holes 13. The through groove 12 is arranged at the center of the raised portion 11. The plurality of connecting holes 13 are point-symmetrically distributed along the center line of the through groove 12, and the plurality of connecting holes 13 respectively penetrate the raised portion 11.

[0055] The provision of the through slot 12 and the communicating hole 13 can effectively reduce the dead weight, which is beneficial to the lightweight design of the brake disc.

[0056] As an implementation method, the material of the brake disc body 1 is aluminum alloy material.

[0057] As another embodiment, the material of the wear-resistant body 2 is carbon-ceramic material.

[0058] The specific working process of the utility model is that two wear-resistant bodies 2 are respectively arranged on both sides of the brake disc body 1, and respectively enclose the outer walls of both sides of the brake disc body 1 to form a filling gap 4, and the filling gap 4 is filled with adhesive, at least two clamping parts 3 are respectively arranged on both sides of the brake disc body 1, and are built into the filling gap 4, the clamping part 3 is connected to any one of the brake disc body 1 and the wear-resistant body 2, and can be matched with the other of the brake disc body 1 and the wear-resistant body 2 to limit the wear-resistant body 2 from sliding relative to the brake disc body 1. Compared with the prior art, the sliding of the wear-resistant body 2 relative to the brake disc body 1 is limited by clamping between the clamping part 3 and the brake disc body 1 and the wear-resistant body 2, and at the same time, the wear-resistant body 2 and the brake disc body 1 are bonded by the adhesive to enhance the connection strength between the two.

[0059] When in use, first install the wear-resistant body 2 on one side on the brake disc body 1, wherein the protrusion 11 is engaged with the recessed portion 21, and the multiple engaging portions 3 are engaged with the multiple engaging grooves respectively, and then fill the filling gap 4 with adhesive, and finally complete the installation and bonding of the wear-resistant body 2 on the other side according to the above steps, and the production of the brake disc is completed.

[0060] The device can solve the technical problem in the prior art that the connection strength between the brake disc body and the wear-resistant layer is not high because the brake disc body and the wear-resistant layer are manufactured and formed by a casting process.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
