Description

Technical Field

[0001] The utility model belongs to the technical field of brake discs, and in particular relates to a carbon-ceramic brake disc suitable for new energy vehicles. Background Art

[0002] In recent years, new energy vehicles have been used by more and more people, and their market share has been increasing due to their excellent driving comfort. However, the brake discs used in the braking system of new energy vehicles are still ordinary metal brake discs, which are heavy, have low heat dissipation efficiency, and low friction coefficient, which leads to low vehicle range and poor braking performance, which is inconsistent with the goal of ultimate driving comfort for new energy vehicles.

[0003] Carbon-ceramic brake discs are undoubtedly the best solution for the braking system of new energy vehicles due to their low weight (about 1 / 3 of metal brake discs), high friction coefficient, high heat dissipation efficiency, and the same life as the discs. Utility Model Content

[0004] In view of the above-mentioned deficiencies existing in the prior art, the utility model provides a carbon-ceramic brake disc suitable for new energy vehicles, so as to solve the problem of low driving comfort caused by insufficient performance of the braking system of new energy vehicles.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A carbon-ceramic brake disc suitable for new energy vehicles comprises a carbon-ceramic brake disc substrate, a friction ring is provided on the surface of the carbon-ceramic brake disc substrate, and a plurality of heat dissipation holes are provided on the friction ring; a heat dissipation groove is provided in an array on the outer periphery of the carbon-ceramic brake disc substrate, and ribs are provided on both sides of the heat dissipation groove; a lace is provided in an array around the inner edge of the carbon-ceramic brake disc, a bolt hole is provided in the middle of the lace, and an assembly platform is provided around the bolt hole.

[0007] Furthermore, the heat dissipation holes and the heat dissipation grooves are completely penetrated.

[0008] Furthermore, the width of the friction ring is 80-100 mm.

[0009] Furthermore, adjacent bolt holes are at the same diameter.

[0010] Furthermore, each group of heat dissipation holes is distributed on the surface of the friction ring in an arc shape as a whole, which is consistent with the rotation direction of the wheel.

[0011] Furthermore, the heat dissipation groove has a thickness of 1 / 3 of the overall thickness of the carbon-ceramic brake disc and is centrally distributed.

[0012] Furthermore, the overall width of the lace is 25-30 mm, and the depth of the assembly platform is 15-20 mm.

[0013] The utility model includes but is not limited to the following beneficial effects:

[0014] (1) The brake disc of the utility model is made of carbon ceramic material, which is 1 / 3 of the weight of a metal disc, thereby increasing the cruising range of new energy vehicles and reducing the cost of using batteries for new energy vehicles. In addition, the carbon ceramic brake disc has the same lifespan, thus reducing the cost of using the vehicle for users.

[0015] (2) After the carbon ceramic brake disc designed by the utility model is matched with the brake pad for friction, the friction coefficient is as high as 0.48-0.50, which improves the overall braking performance of the braking system;

[0016] (3) The design of the heat dissipation groove and the coordination between the heat dissipation groove and the heat dissipation hole in the utility model can introduce the external natural wind into the carbon-ceramic brake disc matrix, thereby improving the heat dissipation efficiency of the friction contact surface and preventing the risk of brake failure caused by continuous high temperature of the carbon-ceramic brake disc;

[0017] (4) The design of the lace structure and the bolt hole in the utility model improves the overall installation strength of the carbon-ceramic brake disc and prevents braking accidents caused by loose parts of the carbon-ceramic brake disc. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1: A carbon ceramic brake disc suitable for new energy vehicles, with a structure referring to Figure 1-3 As shown, it includes a carbon-ceramic brake disc substrate 1, a friction ring 2 is provided on the surface of the carbon-ceramic brake disc substrate 1, and a plurality of heat dissipation holes 3 are provided on the friction ring 2; a heat dissipation groove 4 is provided in an array on the outer periphery of the carbon-ceramic brake disc substrate 1, and each group of heat dissipation holes 3 and the heat dissipation groove 4 are in a completely through-type structure; ribs 5 are provided on both sides of the heat dissipation groove 4; lace 6 is provided in an array around the inner edge of the carbon-ceramic brake disc, a bolt hole 8 is provided in the middle of the lace 6, and an assembly table 7 is provided around the bolt hole 8.

[0024] Among them, in this embodiment, the number of groups of heat dissipation holes 3 is 14 groups, which are arrayed in the friction ring 2 of the carbon-ceramic brake disc, and the number of heat dissipation holes in each group is 8. The overall heat dissipation holes 3 are distributed in an arc shape on the surface of the friction ring 2, which is basically consistent with the rotation direction of the wheel. During the driving of the vehicle, the external natural wind can be brought into the friction ring through the arc structure, ensuring the high heat dissipation efficiency of the friction contact surface and preventing the risk of brake failure caused by the continuous high temperature of the carbon-ceramic brake disc;

[0025] Specifically, the number of heat dissipation slots 4 is 14 groups, and the thickness of a single heat dissipation slot 4 is 1 / 3 of the overall thickness of the carbon ceramic brake disc and is centrally distributed;

[0026] The ribs 5 on both sides of the heat dissipation groove 4 are 15 mm wide and are distributed in an array on the carbon-ceramic brake disc substrate 1; this structure ensures the overall high heat dissipation efficiency of the carbon-ceramic brake disc, while ensuring the excellent mechanical properties of the carbon-ceramic brake disc;

[0027] Around the inner edge of the carbon ceramic brake disc, a lace 6 is arranged in an array; a bolt hole 8 is arranged in the middle of the lace 6, and an assembly platform 7 is provided around the bolt hole 8. Specifically, there are 14 bolt holes, and the diameter of each bolt hole is 10mm, which ensures the overall installation strength of the carbon ceramic brake disc; the assembly platform 7 is 15mm deep, and the overall width of the lace is 30mm, which ensures that the carbon ceramic brake disc and the joint head have high firmness after assembly, and prevents the loosening of parts during the braking process. The design of the lace structure and the bolt hole improves the overall installation strength of the carbon ceramic brake disc and prevents braking accidents caused by loose parts of the carbon ceramic brake disc;

[0028] In this embodiment, the width of the friction ring is 80 mm, which ensures sufficient friction area in the brake system and stabilizes the friction coefficient.

[0029] The carbon ceramic brake disc is processed and formed in one piece, which ensures the overall force and working safety of the product. The carbon ceramic brake disc is made of carbon ceramic material, which is 1 / 3 of the weight of the metal disc, which improves the cruising range of new energy vehicles and reduces the cost of using new energy vehicle batteries. The carbon ceramic brake disc has the same lifespan, which reduces the user's vehicle use cost; after the carbon ceramic brake disc and the brake pad are matched and rubbed, the friction coefficient is as high as 0.48-0.50, which significantly improves the overall braking performance of the braking system.

The heat dissipation holes 3 are distributed in an arc shape on the surface of the friction ring 2, which is basically consistent with the rotation direction of the wheel. During the driving of the vehicle, the external natural wind can be brought into the friction ring through the arc structure, thereby ensuring a high heat dissipation efficiency of the friction contact surface and preventing the risk of brake failure caused by the continuous high temperature of the carbon-ceramic brake disc;

[0031] Specifically, the number of heat dissipation slots 4 is 16 groups, the thickness of a single heat dissipation slot 4 is 1 / 3 of the overall thickness of the carbon ceramic brake disc and is centrally distributed;

[0032] The ribs 5 on both sides of the heat dissipation groove 4 are 25 mm wide and are distributed in an array on the carbon-ceramic brake disc substrate 1; this structure ensures the overall high heat dissipation efficiency of the carbon-ceramic brake disc, while ensuring the excellent mechanical properties of the carbon-ceramic brake disc;

[0033] Lace 6 is arranged in an array around the inner edge of the carbon ceramic brake disc; bolt holes 8 are arranged in the middle of the lace 6, and assembly platforms 7 are arranged around the bolt holes 8. Specifically, the number of bolt holes 8 is 16, and the diameter of each bolt hole 8 is 8mm, which ensures the overall installation strength of the carbon ceramic brake disc; the depth of the assembly platform 7 is 20mm, and the overall width of the lace 6 is 25mm, which ensures that the carbon ceramic brake disc and the joint head have high firmness after assembly, and prevents the loosening of parts during the braking process. The design of the lace structure and bolt holes improves the overall installation strength of the carbon ceramic brake disc and prevents braking accidents caused by loose parts of the carbon ceramic brake disc.
