Description

Technical Field

[0001] The utility model belongs to the technical field of brake discs, and particularly relates to a high-strength carbon-ceramic brake disc assembly for heavy-duty trucks. Background Technique

[0002] The brake disc is a main component for vehicle braking. When a vehicle brakes from running, it mainly relies on the mutual cooperation and friction between the brake disc and the brake pads. During the friction process, high temperatures will be generated, resulting in too high temperatures for the brake disc and the brake pads. Most of the existing brake disc materials are cast iron discs, which have large self-weights, significant wear during braking, long braking distances during emergency braking, are prone to corrosion when driving in rainy or humid weather, and have slow heat dissipation. All of the above problems will pose a risk of brake failure.

[0003] Heavy-duty trucks have a relatively long continuous driving time and relatively poor road conditions. The vehicle itself is heavy and has a large load, and the brake disc works continuously for a long time. Ordinary cast iron brake discs can no longer meet the braking requirements of heavy-duty trucks. Therefore, a high-strength carbon-ceramic brake disc assembly with excellent performance, with its super braking performance, high wear resistance, excellent corrosion resistance, high heat resistance, and low mass, is undoubtedly an excellent substitute for the brake discs of heavy-duty trucks. Content of the Utility Model

[0004] In view of the above deficiencies existing in the prior art, the utility model provides a high-strength carbon-ceramic brake disc assembly for heavy-duty trucks to solve the drawbacks existing in the brake discs for heavy-duty trucks.

[0005] A high-strength carbon-ceramic brake disc assembly for heavy-duty trucks includes a carbon-ceramic brake disc, a hub, fixing screws, and gaskets. The fixing screws sequentially pass through the gaskets, the bolt holes of the carbon-ceramic brake disc, and the connection holes of the hub to connect and fix the carbon-ceramic brake disc and the hub; a number of ventilation holes are arrayed on the surface of the carbon-ceramic brake disc, and a toothed groove is opened at the inner edge of the carbon-ceramic brake disc; a concave platform is arranged between two adjacent connection holes on the hub, and a through hole is opened on the shaft side of the hub; assembly screw holes are opened at the installation position of the hub and the vehicle shaft, and a semi-circular groove is opened between two adjacent assembly screw holes.

[0006] Further, the ventilation holes are oval ventilation holes, and the number of ventilation holes is 40 - 60.

[0007] Further, the number of toothed grooves is 20 - 28.

[0008] Further, the bolt holes are arranged at intervals on the toothed grooves.

[0009] Further, the number and size of the bolt holes and the connection holes are equal, and their positions correspond.

[0010] Further, the depth of the connection holes is 35 mm.

[0011] Furthermore, the number of through holes is 30 - 40.

[0012] Furthermore, the thickness of the gasket is 2 - 3 mm.

[0013] The beneficial effects of the present utility model are as follows:

[0014] In the present utility model, the brake disc is made of carbon-ceramic material, and its own weight is 1 / 3 of that of an ordinary cast iron disc. The lower weight can reduce the unsprung weight of the vehicle, increase the driving range of the vehicle, and save costs;

[0015] In the present utility model, oval ventilation holes are arrayed on the carbon-ceramic brake disc. This structure can form a continuous flowing air layer on the surface of the carbon-ceramic brake disc during vehicle driving, and continuously reduce the temperature of the brake disc;

[0016] In the present utility model, a continuous toothed groove is designed at the inner edge of the carbon-ceramic brake disc. This structure can continuously bring external natural wind to the inner edge of the carbon-ceramic brake disc, and reduce the temperature of the brake disc through the exchange between the natural wind and the heat of the disc body;

[0017] In the present utility model, concave platforms are arrayed on the adapter. The design of this structure improves the installation strength between the adapter and the carbon-ceramic brake disc, disperses the impact force during vehicle braking, and can effectively reduce the surface temperature of the brake disc.

[0027] A high-strength carbon-ceramic brake disc assembly for heavy-duty trucks, the structure is referred to Figure 1-2 as shown, including a carbon-ceramic brake disc 1, a hub 5, fixing screws 11 and gaskets 12. The fixing screws 11 sequentially pass through the gaskets 12, the bolt holes 3 of the carbon-ceramic brake disc 1 and the connection holes 9 of the hub 5 to connect and fix the carbon-ceramic brake disc 1 and the hub 5;

[0028] Refer to Figure 3 as shown, a number of ventilation holes 2 are arrayed on the surface of the carbon-ceramic brake disc 1. The ventilation holes 2 are oval in shape, and the number is 40 - 60. This structure can form a continuous flowing air layer on the surface of the carbon-ceramic brake disc during vehicle driving, continuously reducing the temperature of the brake disc;

[0029] Tooth-shaped grooves 4 are provided at the inner edge of the carbon-ceramic brake disc 1, and the number is 20 - 28. This structure can continuously bring external natural wind to the inner edge of the carbon-ceramic brake disc 1, and reduce the temperature of the brake disc through the exchange between the natural wind and the heat of the disc body;

[0030] Bolt holes 3 are arrayed at the inner edge of the carbon-ceramic brake disc 1. This structure is used to connect the carbon-ceramic brake disc 1 and the hub 5. The bolt holes 3 are arranged at intervals on the tooth-shaped grooves 4. Connection holes 9 are provided on the hub 5, and the depth of the connection holes 9 is 35 mm; the number and size of the bolt holes 3 and the connection holes 9 are equal, and the positions correspond one by one.

[0031] Refer to Figure 4As shown, a concave platform 10 is arranged between two adjacent connection holes 9 on the joint head 5. When the vehicle brakes, a strong force will be generated, and the contact part between the carbon-ceramic brake disc 1 and the joint head 5 will generate a large impact force. Moreover, the large contact area will generate a high temperature. The concave platform 10 improves the installation strength of the joint head 5 and the carbon-ceramic brake disc 1, effectively dispersing the impact force when the vehicle brakes, and the grooves at the contact part between the carbon-ceramic brake disc 1 and the joint head 5 can effectively reduce the surface temperature.

[0032] The joint head 5 is provided with 30-40 through holes 8 on the axial side. This structure can effectively reduce the weight of the carbon ceramic brake disc assembly and help dissipate heat.

[0033] An assembly screw hole 6 is provided at the joint 5 and the vehicle shaft for mounting the brake disc assembly on the vehicle; a semicircular groove 7 is provided between two adjacent assembly screw holes 6; the semicircular groove 7 can improve the mounting strength between the brake disc assembly and the vehicle, effectively disperse the impact force during vehicle braking, and effectively reduce the surface temperature of the brake disc assembly;

[0034] In this embodiment, the gasket 12 has a thickness of 2-3 mm and is placed on the bolt hole 3 of the carbon-ceramic brake disc, below the head of the fixing screw 11. The gasket 12 can effectively reduce the impact force generated at the connection between the carbon-ceramic brake disc 1 and the joint 5 when the vehicle brakes, thereby improving the strength and safety of the brake disc assembly.

[0035] The brake disc assembly is installed as follows: first, the assembly surface of the carbon ceramic brake disc 1 is in contact with the bottom of the joint head 5, and the bolt holes 3 are aligned with the connecting holes 9 at the bottom of the joint head 5. Then, the gaskets 12 are installed one by one at the inner edge bolt holes 3 of the carbon ceramic brake disc 1. Finally, the fixing screw 11 is passed through the gasket 12, the carbon ceramic brake disc bolt hole 3, and the connecting hole 9 in sequence to form the final high-strength carbon ceramic brake disc assembly for heavy trucks (refer to Figure 5 as shown).
