Description

Technical Field

[0001] The present application relates to the technical field of brake equipment, and in particular to a floating device connected to a 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] As the new energy vehicle market continues to expand and technology matures, major manufacturers are seeking to reduce costs through technology, with brake disc assemblies being a key area of ​​focus. Currently, the mainstream brake disc material on the market is metal, which suffers from numerous drawbacks, including heavy weight, slow heat dissipation, and a low friction coefficient. Consequently, split carbon-ceramic brake discs, offering superior overall performance, have emerged and are highly sought after by many modified vehicles. However, metal brake discs remain the preferred choice for car manufacturers due to their low price. As carbon-ceramic brake disc manufacturers continue to mature their technology, their costs are gradually decreasing, leading to a decrease in price. Soon, carbon-ceramic brake discs will also enter the market at a similarly low price.

[0004] Although split-type carbon-ceramic brake discs offer excellent performance, their design and structure still present the following drawbacks. First, most of the connection structures utilize a simple screw and nut combination. While this structure is simple to design and install, it can damage the carbon-ceramic brake disc during use. Carbon-ceramic brake discs are hard and brittle. During installation, the screw is passed through the disc's screw holes, and the joint is then tightened with the nut. During braking, the vehicle generates significant impact force, and the screw impacts the disc's screw holes with this force, damaging the disc and reducing its performance and lifespan. In severe cases, this can lead to traffic accidents. Second, the carbon-ceramic brake disc and joint are in contact, and the heat generated by friction braking during vehicle operation is directly transferred to the joint, causing deformation of the material. Utility Model Content

[0005] The present application provides a floating device for connecting a carbon-ceramic brake disc and a joint, which can effectively avoid the above-mentioned technical problems, ensure the installation strength of the carbon-ceramic brake disc assembly, and protect the safety of the driver.

[0006] A floating device for connecting a carbon-ceramic brake disc assembly is provided, comprising:

[0007] The floating block is a T-shaped cylindrical structure with a hollow interior, including a top cylindrical structure and a bottom cylindrical structure; the top cylindrical structure has a diameter of 10-12mm and a height of 2-3mm; the bottom cylindrical structure has a diameter of 6-8mm and a height of 30-50mm;

[0008] The gasket is provided on the contact surface between the carbon ceramic brake disc and the joint head; the width of the front side of the gasket is greater than the width of the rear side;

[0030] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B means: A or B.

[0031] 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.

[0032] Combine Figure 1-2 As shown, the embodiment of the present disclosure provides a floating device for connecting a carbon-ceramic brake disc assembly, comprising a screw 1, a floating block 2, a gasket 3, a locking nut 4,

[0033] The floating block 2 is the main structure, made of 316 stainless steel. The overall structure is divided into two parts. The first part is the top cylindrical structure 2-1, with a diameter of 10-12mm and a height of 2-3mm. The second part is the bottom cylindrical structure 2-2, with a diameter of 6-8mm and a height of 30-50mm.

[0034] Specifically, both sides of the cylindrical structure 2 - 1 at the top of the slider 2 are chamfered to a size of C0.5-C1.

[0035] Optionally, the size of the cylindrical structure 2-2 at the bottom of the floating block 2 needs to refer to the sizes of the carbon-ceramic brake disc 5, the gasket 3, and the joint 6; specifically, the cylindrical structure 2-2 at the bottom of the floating block 2 must not exceed the surface of the carbon-ceramic brake disc 5 after passing through the bolt hole of the carbon-ceramic brake disc 5, so the bottom of the floating block 2 and the surface of the carbon-ceramic brake disc 5 are designed with a tolerance of 1-2mm to ensure the installation of other components; this design can ensure that there is a certain floating space around the cylindrical part of the split carbon-ceramic brake disc 5 during use, thereby effectively avoiding damage to the carbon-ceramic brake disc 5.

[0036] At the same time, the design of the floating block 2 completely avoids damage to the carbon-ceramic brake disc 5 caused by direct contact between the screw 1 and the bolt hole of the carbon-ceramic brake disc 5, thereby improving the service life and installation strength of the carbon-ceramic brake disc 5;

[0037] Optionally, the entire structure of the floating block 2 is an integrally formed structure, which has high safety strength;

[0038] Optionally, the gasket 3 is made of 316 stainless steel and is disposed at the contact portion between the carbon-ceramic brake disc 5 and the joint 6. The height is 2-3 mm, and the entire outer edge of the gasket 3 does not protrude beyond the outer edge of the joint 6. The gasket changes the contact type between the carbon-ceramic brake 5 and the joint 6 to a non-contact type, thereby preventing the heat generated by the carbon-ceramic brake disc 5 from being transferred to the joint 6 and causing thermal deformation of the material.

[0039] Among them, the material of screw 1 and locking nut 4 are both 316 stainless steel, and the size of screw 1 and locking nut 4 is M6 / M8. The torque of screw 1 and locking nut 4 is set to 10.8N·m. The carbon-ceramic brake disc assembly installed under this torque has high safety strength, and the nut is a locking type. After installation, the entire floating device is not easy to loosen.

[0040] The floating device is used in the following manner: first, the carbon-ceramic brake disc 5 is placed horizontally with the assembly surface facing upward; secondly, the gasket 3 is placed in an array on the bolt holes of the carbon-ceramic brake disc 5, with the center holes aligned; secondly, the joint head 6 is placed horizontally above the gasket 3, with the slot of the joint head 6 aligned with the center hole of the gasket 3; secondly, the floating block 2 is passed through the joint head 6, the gasket 3, and the carbon-ceramic brake disc 5 in sequence; then, the screw 1 is passed through the floating block 2, the joint head 6, the gasket 3, and the carbon-ceramic brake disc 5 in sequence; finally, the locking nut 4 is locked with the screw 1 to complete the assembly of the carbon-ceramic brake disc assembly (refer to Figure 3 shown).

[0041] 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.
