Description

Technical Field

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

[0002] Special vehicles often operate in harsh road conditions, subjecting them to frequent emergency braking and sustained high-load conditions. Ordinary metal brake discs, due to their low heat dissipation efficiency, heavy weight, low friction performance, and tendency to deform after continuous operation, hinder the optimal braking performance of special vehicles in these complex operating environments. The shortcomings of metal brake discs can even lead to failure during emergency braking, resulting in serious consequences. Therefore, a high-performance carbon-ceramic brake disc assembly is undoubtedly an excellent solution to these problems. Utility Model Content

[0003] In response to the above-mentioned deficiencies in the prior art, the utility model provides a high-strength carbon-ceramic brake disc assembly for special vehicles, which is used to solve the problem of low overall performance of ordinary metal brake discs for special vehicles when facing complex working conditions.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A high-strength carbon-ceramic brake disc assembly for special vehicles includes a base plate, a carbon-ceramic friction block, and a screw. The base plate is provided with a circular through hole and a bolt hole. The carbon-ceramic friction block is provided with a countersunk hole, a cylindrical protrusion, and a ventilation groove around the base. The screw passes through the countersunk hole and the circular through hole in sequence to securely connect the base plate and the carbon-ceramic friction block.

[0006] Furthermore, a buffer groove and a screw hole are provided on the outer edge of the bottom plate.

[0007] Furthermore, the diameter of the circular through hole is equal to the diameter of the bolt hole.

[0008] Furthermore, during installation, the cylindrical protrusions are inserted into the circular through holes; the number and diameter of the cylindrical protrusions are equal to the number and diameter of the circular through holes opened on the bottom plate.

[0009] Furthermore, the ventilation slot is an arc-shaped structure.

[0010] Furthermore, the number of the ventilation grooves is 8-10, the width is 2-5 mm, and the depth is 1 / 3-2 / 3 of the thickness of the carbon ceramic friction block.

[0011] Furthermore, the inner and outer edges of the carbon-ceramic brake disc are provided with chamfered surfaces with a size of 1.5-2 mm.

[0012] The utility model includes but is not limited to the following beneficial effects:

[0013] (1) The carbon-ceramic brake disc assembly of the present invention is made of carbon-ceramic material, which is 1 / 3 of the weight of a metal disc. This improves the mileage of new energy vehicles and reduces the cost of using batteries for new energy vehicles. At the same time, the life of the carbon-ceramic material is the same as that of the disc, which greatly reduces the cost of using the vehicle for users.

[0014] (2) In the present invention, multiple ventilation slots are provided in the friction block to improve the heat dissipation efficiency of the entire brake disc, reduce the operating temperature of the brake disc, and prevent the risk of brake failure caused by continuous high temperature of the brake disc;

[0025] 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 with reference to the accompanying drawings and embodiments.

[0026] Example 1: A high-strength carbon ceramic brake disc assembly for special vehicles, with a structure referring to Figure 1-Figure 7 As shown, it includes a base plate 1, a carbon-ceramic friction block 6, and a screw 10. The base plate 1 is provided with a circular through hole 2 and a bolt hole 3. The carbon-ceramic friction block 6 is provided with a countersunk hole 7, a cylindrical protrusion 9, and a ventilation slot 8 around the base. The screw 10 passes through the countersunk hole 7 and the circular through hole 2 in sequence to securely connect the base plate 1 and the carbon-ceramic friction block 6.

[0027] In this embodiment, the diameter of the circular through-holes 2 is equal to the diameter of the bolt holes 3. The number and diameter of the cylindrical protrusions 9 are equal to the number and diameter of the circular through-holes 2 in the base plate 1. The number and diameter of the countersunk holes 7 in the carbon-ceramic friction block 6 are equal to the number and diameter of the bolt holes 3 in the base plate 1. This structural design ensures that the screw 10 can accurately lock the carbon-ceramic friction block 6 and base plate 1 together after they are mated. Specifically, there are eight circular through-holes, each with a diameter of 22 mm, and eight M5 bolt holes.

[0028] In this embodiment, the outer edge of the bottom plate is provided with a buffer groove 5 and a screw hole 4. The number of the buffer grooves 5 is 6. This structure can effectively reduce the stress generated during the braking process and increase the stress release rate.

[0029] The ventilation slots 8 on the carbon-ceramic friction pad 6 are arc-shaped, with their width on the inner circumference equal to their width on the outer circumference. Specifically, there are eight ventilation slots 8, each 5mm wide and 1 / 3 the thickness of the carbon-ceramic friction pad 6. This design ensures that heat from the carbon-ceramic friction pad is dissipated promptly, effectively reducing the overall brake disc temperature.

[0030] In this embodiment, the inner and outer edges of the carbon-ceramic brake disc are provided with chamfered surfaces with a size of 1.5-2 mm. This design can prevent the brake disc from being bumped during use and causing the disc body to break and break.

[0031] The installation method of the carbon ceramic brake disc assembly is:

[0032] The installation of the base plate 1 and the carbon ceramic friction block 6 is completed by inserting the cylindrical protrusion 9 on the carbon ceramic friction block 6 into the circular through hole 2 on the base plate 1, and the installation of the entire carbon ceramic brake disc assembly is completed by passing the screw 10 through the countersunk hole 7 on the carbon ceramic friction block 6 and locking it with the bolt hole 3 on the base plate 1.

[0033] The carbon-ceramic brake disc assembly adopts a split structural design, which is easy to disassemble. When parts are damaged, they can be replaced in a timely and convenient manner, and the work efficiency is high.

[0034] Example 2 A high-strength carbon ceramic brake disc assembly for special vehicles, the structure is still referenced Figure 1-Figure 7 As shown, the difference from Example 1 is that the number of circular through holes is 10, and the diameter of the circular through holes is 18 mm; the bolt holes can be M6 or M8, and the number is 10.

[0035] The number of the buffer grooves 5 is 8; the number of the ventilation grooves 8 is 10, the width is 2 mm, and the depth is 2 / 3 of the thickness of the carbon ceramic friction block 6.
