Description

Technical Field

[0001] The utility model belongs to the technical field of brake equipment, and in particular relates to a floating device connecting a carbon ceramic brake disc and a joint head. Background Art

[0002] Traditional brake discs are mostly cast in one piece, which have defects such as heavy weight, slow heat dissipation, and vibration. As people are increasingly pursuing the performance and safety of automobiles, carbon ceramic brake discs have emerged. Split carbon ceramic brake discs are undoubtedly an excellent solution to the above problems, but the existing common split carbon ceramic brake discs have a simple structural design. Most of them use screws and nuts to lock the brake disc with the joint. The screw goes straight through the bolt hole of the carbon ceramic brake disc and directly contacts the carbon ceramic brake disc body. In order to ensure strength, the screw and the bolt hole of the carbon ceramic brake disc fit closely.

[0003] This structural design has the following defects: first, the carbon-ceramic brake disc is brittle, and the screw and nut will damage the carbon-ceramic brake disc when the car brakes; second, the structural design is simple, with only the screw and nut working together, and the screw and nut are easy to loosen after frequent braking; third, the joint is in direct contact with the carbon-ceramic brake disc, and at high temperatures, the heat of the brake disc will be quickly transferred to the joint, causing thermal deformation of the material. All of the above will cause the risk of failure of the braking system. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a floating device connecting a carbon-ceramic brake disc and a joint head, which solves the problem of damage to the carbon-ceramic brake disc caused by the existing ordinary split carbon-ceramic brake disc during automobile braking, the problem of loosening of the existing ordinary split carbon-ceramic brake disc caused by frequent braking, and the problem of thermal deformation of the material caused by the high temperature of the ordinary split carbon-ceramic brake disc, thereby improving the braking performance of the vehicle and ensuring the life safety of the driver.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A floating device for connecting a carbon ceramic brake disc and a joint head, the floating device comprising a floating block, a gasket, an elastic pressure plate, a nut and a screw; the elastic pressure plate, the floating block and the gasket are all provided with through holes penetrating the body; the elastic pressure plate is fixed on the top of the floating block, the gasket is located in the middle and lower part of the floating block; the screw extends upward from the bottom of the floating block; the nut is screwed on one end of the screw;

[0009] Preferably, two bent ends are symmetrically provided on both sides of the elastic pressing sheet, and the two bent ends are pressed and fixed on the sinking platforms on both sides of the top of the floating block.

[0010] Further preferably, the top surface of the elastic pressing sheet is provided with a circular structure, and the difference between the diameter of the circular structure and the bottom diameter of the nut is greater than 1 mm.

[0011] Preferably, the gasket is arranged between the carbon-ceramic brake disc and the joint head to play a connecting role.

[0012] Preferably, the thickness of the gasket is 3-5 mm.

[0013] Preferably, the thickness of the elastic pressing sheet is greater than 0.5 mm.

[0014] The utility model includes but is not limited to the following beneficial effects:

[0015] An integral floating device is used to connect the carbon-ceramic brake disc and the joint head.

[0021] 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 in conjunction with the accompanying drawings and embodiments.

[0022] Embodiment 1:

[0023] A floating device connecting a carbon ceramic brake disc and a joint head, the structure is as follows Figure 1-2 As shown, it includes nut 1, elastic pressing plate 2, floating block 3, gasket 4 and screw 5; elastic pressing plate 2, floating block 3 and gasket 4 are all provided with through holes penetrating the body; the assembly order of the whole floating device from top to bottom is nut 1, elastic pressing plate 2, floating block 3, gasket 4, screw 5, and they are all coaxial to ensure the overall floating and safety of the whole floating device. The specific position relationship is: elastic pressing plate 2 is fixed on the top of floating block 3, gasket 4 is located in the middle and lower part of floating block 3; screw 5 goes upward from the bottom of floating block 3; nut 1 is tightened on one end of screw 5.

[0024] Specifically, the floating block 3 is the main structure of the floating device, with a 4-5mm cylindrical structure at the top, a square structure in the middle, and rounded corners on all sides, and a long cylindrical structure at the bottom of 11-22mm. The two sides of the top cylindrical structure are symmetrically provided with sinking platforms, and the walls of the sinking platforms are processed with large rounded corners; the top cylindrical structure, the middle square structure, and the long cylindrical structure at the bottom of the floating block 3 are integrally cast, ensuring the excellent mechanical properties of the floating block 3.

[0025] In this embodiment, the bottom surface of the elastic pressing sheet 2 is tightly fitted with the top surface of the floating block 3, and two bent ends are symmetrically provided on both sides of the elastic pressing sheet 2, and the two bent ends are pressed and fixed to the sinks on both sides of the top of the floating block 3. This design can make full use of the elastic pressing sheet 2 to offset the impact stress generated at the locking point of the screw rod 5 and the nut 1 when the car brakes, thereby preventing the nut 1 from loosening;

[0026] Specifically, a circular structure is provided on the top surface of the elastic pressing sheet 2, and the diameter of the circular structure differs from the bottom diameter of the nut 1 by more than 1 mm, so as to ensure a sufficiently large contact area between the elastic pressing sheet 2 and the nut 1;

[0027] A through hole with the same diameter as the floating block 3 is provided at the center of the elastic pressing sheet 2. After being installed with the floating block 3, the through hole of the elastic pressing sheet 2 and the through hole of the floating block 3 are coaxial, ensuring that the screw 5 can smoothly pass through the through hole and be locked with the nut 1;

[0028] Both sides of the circular structure on the top surface of the elastic pressing sheet 2 and the two bent ends are opened to ensure that the elastic pressing sheet will not deform when the stress is released;

[0029] The gasket 4 is located between the carbon-ceramic brake disc 9 and the joint 6, with a thickness of 3-5 mm. It is arranged in coordination with the bolt hole array of the carbon-ceramic brake disc 9, playing a connecting role, ensuring that there is a gap between the carbon-ceramic brake disc 9 and the joint 6 for heat dissipation, thereby avoiding the problem of thermal deformation of the material caused by high temperature.

[0030] The entire floating device is made of SUS316 material, and the thickness of the elastic pressing sheet is greater than 0.5mm, which ensures the overall strength of the floating device.

[0031] Reference Figure 3-Figure 4 The steps for using this floating device are as follows:

[0032] (1) Place the gasket 4 array on the friction surface of the carbon ceramic brake disc 9 and match the bolt holes of the carbon ceramic brake disc 9;

[0033] (2) Place the joint 6 on the gasket 4 so that the outer circular notch 7 of the joint coincides with the center of the gasket 4;

[0034] (3) Insert the floating block 3 array into the bolt hole of the carbon ceramic brake disc 9;

[0035] (4) Placing the elastic pressing sheet 2 array on the top of the floating block 3 to ensure that the two are coaxial; wherein the two bent ends on both sides of the elastic pressing sheet 2 are pressed and fixed to the sinking table surfaces on both sides of the top of the floating block 3;

[0036] (5) The screw rod 5 array is sequentially passed through the bolt hole of the carbon ceramic brake disc 9, the gasket 4, the floating block 3, and the elastic pressing piece 2;

[0037] (6) The nut 1 array is locked with the screw 5 to complete the installation of the split carbon-ceramic brake disc.

[0038] Embodiment 2:

[0039] A floating device connecting a carbon-ceramic brake disc and a joint head has a structure as described in Example 1, except that the height difference between the sinking surface on both sides of the cylindrical structure at the top of the floating block 3 and the contact surface of the bent ends on both sides of the elastic pressing plate 2 is 1 mm. Through this structure, the impact stress on the locking point of the screw 4 and the nut 1 during the braking of the automobile is offset, thereby preventing the screw 4 and the nut 1 from loosening and ensuring the firmness of the split carbon-ceramic brake disc.

[0040] Embodiment 3:

[0041] A floating device connecting a carbon-ceramic brake disc and a joint has a structure as described in Example 1, except that the diameter of the long cylindrical structure at the bottom of the floating block 3 and the diameter of the bolt hole of the carbon-ceramic brake disc 9 differ by 1 mm. The floating of the long cylindrical structure at the bottom of the floating block 3 ensures that the bolt hole of the carbon-ceramic brake disc 9 will not be damaged when the car brakes.

[0042] Embodiment 4:

[0043] A floating device connecting a carbon-ceramic brake disc and a joint head has a structure as described in Example 1, except that the length of the long cylindrical structure at the bottom of the floating block 3 is the same as the length of the bolt hole of the carbon-ceramic brake disc 9, ensuring that there is no structural interference when the screw passes through the floating device and is locked with the nut.

[0044] The utility model solves the problem of damage to the carbon-ceramic brake disc caused by the existing common split-type carbon-ceramic brake disc during automobile braking through the overall floating structure design; solves the problem of loosening of the locking device of the common split-type carbon-ceramic brake disc caused by frequent braking through the design of the elastic pressing plate in the floating device; solves the problem of thermal deformation of the material caused by the rapid transfer of heat from the carbon-ceramic brake disc to the joint head due to the lack of heat insulation treatment between the joint head and the brake disc of the existing common split-type carbon-ceramic brake disc through the design of the split gasket in the floating device.
