Description

Technical Field

[0001] The present application relates to the technical field of brake equipment, for example, to a combined high-strength carbon-ceramic brake disc assembly. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] Brake disc is one of the important components of automobile braking system. With the continuous maturity of domestic new energy vehicle technology, the market share of new energy vehicles has been growing year by year. Major automakers have been laying out the new energy vehicle market. Lightweight is an important indicator for new energy vehicles. Lighter vehicle weight will bring longer driving range and reduce battery cost. Therefore, carbon ceramic brake disc has a lighter weight than metal disc (carbon ceramic brake disc density 2.3g / cm 3 , metal brake disc density 7.6g / cm 3 Carbon ceramic brake discs of the same specifications (which are about 1 / 3 the weight of metal brake discs) will become the standard brake disc material for future vehicle manufacturers.

[0004] Carbon ceramic brake discs have many excellent properties due to their material advantages, but there are still some disadvantages. Although carbon ceramic brake discs are harder than metal brake discs, they are also more brittle. When the disc body is bumped, it will cause cracking and falling off. Carbon ceramic brake discs are more expensive due to their special craftsmanship, about 10 times that of metal brake discs. When the disc body is bumped and damaged, replacing the carbon ceramic disc will incur high costs.

[0005] Based on the above problems, this technology was developed. Utility Model Content

[0006] The present application provides a combined high-strength carbon-ceramic brake disc assembly. When a carbon-ceramic brake disc is partially damaged, the damaged part can be replaced, and the parts can be easily disassembled, avoiding the high cost of replacing the entire disc and significantly reducing maintenance costs.

[0007] A combined high-strength carbon-ceramic brake disc assembly is provided, comprising:

[0008] The base body is an annular structure with bolt holes arranged in an array along the inner edge;

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0036] Combine Figure 1-4 As shown, the embodiment of the present disclosure provides a combined high-strength carbon-ceramic brake disc assembly, including a carbon-ceramic disc substrate 10, a carbon-ceramic sheet 20, a screw 30, and a nut 40;

[0037] The carbon-ceramic brake disc substrate 10 has 10-12 bolt holes 101 arrayed along its inner edge. The bolt holes 101 have a diameter of 8-10 mm, and the inner wall thickness of the bolt holes 101 and the carbon-ceramic disc substrate 10 is 4.5-6 mm. This structure is used to assemble the disc, improve assembly strength, reduce the buffering force generated by service braking, and protect the bolt holes of the carbon-ceramic disc from damage.

[0038] Preferably, the carbon ceramic disc base 10 has 2-3 circles of mounting screw holes 102 distributed along the pitch circle. The mounting screw holes 102 are of M6 / M8 specification and 24-30 in number. The spacing between two adjacent mounting screw holes 102 is 5-7 mm. The mounting screw holes 102 are used to mate the carbon ceramic sheet 20 with the carbon ceramic disc base 10 and are locked together by the screw 30 and the nut 40 to complete the assembly.

[0039] Preferably, a groove 201 is provided in the middle of the carbon ceramic disc 20. The groove 201 has a width of 2-3 mm and a depth of 6-8 mm, and has R1 rounded corners on both sides. This structure is designed to reduce friction resistance through the gap when the discs rub against each other during braking, thereby improving braking safety.

[0040] Preferably, a sink 202 is provided on both sides of the carbon ceramic sheet 20, the width of the sink 202 is 10-12 mm, the depth is 5-6 mm, and 2-3 connecting screw holes 203 are provided on the sink 202, the specification is M6 / M8, and the distance between two adjacent connecting screw holes 203 is 5-7 mm; the position of the connecting screw hole 203 matches the installation screw hole 102.

[0041] The positions of the sinks 202 on both sides are the starting and ending points of friction. This structure can effectively reduce the noise generated during the braking process and improve the NVH performance.

[0042] Further preferably, the gap between two adjacent carbon ceramic pieces 20 is 8-12 mm, and the total number of carbon ceramic pieces is 12-14, which are evenly and symmetrically distributed on both sides of the carbon ceramic plate base. This structure can effectively improve the cooling rate of the carbon ceramic plate and accelerate heat dissipation.

[0043] The thickness ratio of the carbon ceramic plate base 10 and the carbon ceramic sheets 20 on both sides is basically designed to be 1:1:1, and the overall thickness is 28-32mm, which ensures the strength of the combined carbon ceramic plate.

[0044] Installation and use method: The material of the screw 30 and the nut 40 are both SUS316. The screw 30 passes through the connecting screw hole 203, the installation screw hole 102, and the connecting screw hole 203 of the carbon ceramic piece on the other side in sequence, and then cooperates with the nut 40 to lock the carbon ceramic disc to complete the installation.

[0045] The carbon-ceramic brake disc assembly provided by the utility model is made of carbon-ceramic material as a whole. Its own weight is 1 / 3 of that of an ordinary cast iron disc, which meets the goal of lightweighting new energy vehicles. At the same time, it can increase the vehicle's cruising range and reduce battery costs. At the same time, the combined structural design can significantly reduce maintenance costs.

[0046] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless expressly required, individual components and functions are optional, and the order of operations may vary. Portions and features of some embodiments may be included in or replace portions and features of other embodiments. The embodiments of the present disclosure are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
