Description

Technical Field

[0001] The utility model belongs to the field of brake structures, and in particular relates to a torsion block structure of an integrated carbon-ceramic brake disc joint. Background Art

[0002] Carbon ceramic brake discs are made of carbon fiber reinforced silicon carbide-based composite materials. They combine the physical properties of carbon fiber and polycrystalline silicon carbide, and have the advantages of low density, high temperature resistance, high friction performance and stability. They have broad application prospects in high-energy braking fields such as automobiles, high-speed trains, and aircraft. The carbon ceramic brake disc joint is the central circular component that connects the carbon ceramic brake disc and the wheel hub. It is generally made of aluminum alloy or stainless steel and is installed on the brake disc with a joint screw. The joint screw usually consists of a torque block, a screw, a gasket, and a nut. In order to make carbon ceramic brake discs more widely used in civilian vehicles, it is necessary to reduce the production cost of carbon ceramic brake discs from all aspects. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the conventional carbon ceramic brake disc joint torque block is made by turning and milling a whole piece of material. During the processing, the bar material needs to be turned into a circle according to the size, then the three surfaces are milled flat, and finally holes are drilled. There are many processing steps and the cost is high. The purpose of the utility model is to reduce the manufacturing cost of the joint bolt torque block, and an integrated carbon ceramic brake disc joint torque block is proposed to achieve the purpose.

[0004] In order to solve the above technical problems, the solution of the utility model is: a torque block structure of an integrated carbon-ceramic brake disc joint, including a torque block for connecting the carbon-ceramic brake and the joint, the torque block including an upper section and a lower section that are integrally arranged, and a drill hole is opened through the upper section and the lower section.

[0005] The upper section has a diameter of 22 mm and a height of 5 mm.

[0006] The lower section has a height of 8 mm and a diameter of 12 mm.

[0007] The diameter of the drilled hole is 5 mm.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The utility model adopts an integrated torsion block structure, which reduces the processing steps of the torsion block and can be completed by using only a lathe, thereby improving processing efficiency and reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0016] As Figure 3 shown, a torsion block structure of an integrated carbon-ceramic brake disc joint of the present utility model includes a torsion block 1 for connecting a carbon-ceramic brake 2 and a joint 3. The torsion block 1 includes an upper section 11 and a lower section 12 which are integrally arranged, and a drilling hole 13 is penetrated between the upper section 11 and the lower section 12.

[0017] As Figure 4 shown, in the present utility model, the diameter of the upper section 11 of the torsion block 1 is 22 mm, the height is 5 mm, the height of the lower section 12 is 8 mm, and the diameter is 12 mm; the diameter of the drilling hole 13 is 5 mm.

[0018] During the machining of the present utility model, the machining of the upper section 11, the lower section 12 and the drilling hole 13 can be completed only on a lathe.

[0019] In order to verify the effect of the present utility model, the structure of the present utility model and a conventional structure are compared using the finite element simulation method. The comparison process is as follows: Fix the side of the brake disc and apply torque to the 5 bolt mounting holes of the joint, as Figure 5 shown. Observe the changes of the torsion block and the effects on the joint, bolts and torsion block. When using the floating block of the present utility model, the maximum stress of the bolts is reduced by 23%, the maximum stress of the joint remains unchanged, and the maximum stress of the torsion block is reduced by 21%. The conclusion is that after using the torsion block of the present utility model, the stress of each component does not increase, and the stress of the bolts and the torsion block is reduced, which is beneficial to the structural strength.

[0020] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
