Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a brake disc assembly and a vehicle having the same. Background Technology

[0002] In traditional brake disc assemblies, the coupling and disc body are directly connected by bolts. Due to the differences in the coefficient of thermal expansion and thermal conductivity of the materials of the coupling, connecting components and disc body, large thermal stress is easily generated at the tightening position of the connecting bolts and nuts at high temperatures. This can easily lead to bolt deformation or loosening and failure, affecting the overall NVH (Noise, Vibration, and Harshness) performance or safety of the vehicle. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a brake disc assembly in which the heat generated by the disc body can be effectively transferred to the contact head during braking, thus avoiding axial runout caused by thermal stress concentration in the disc body and improving the NVH of the entire vehicle.

At the same time, the connection between the annular washer and the disc body is in a surface contact state, which is beneficial to the end runout stability of the disc body and makes the end runout consistency of the brake disc assembly better. The annular washer can make the contact area between the clutch and the disc body larger, so that the heat generated by the disc body can be better transferred to the clutch when the brake disc assembly brakes. The process of the clutch receiving the high temperature of the disc body is more uniform, which can avoid the thermal stress concentration of the disc body and the axial runout, which is beneficial to improving the NVH of the whole vehicle.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] The brake disc assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0042] like Figure 1 and Figure 2 As shown, the brake disc assembly 100 according to an embodiment of the present invention includes a disc body 1, a head 2, an annular gasket 3, and a plurality of first fasteners 4.

[0043] Specifically, the brake disc assembly 100 is used in a vehicle. The brake disc assembly 100 generates braking force through friction with the brake pads, ensuring that the vehicle can safely decelerate or stop during driving. When the driver presses the brake pedal, the brake fluid pushes the piston, causing the brake pads to fit tightly against the brake disc assembly 100, thereby generating a frictional torque to achieve deceleration and braking.

[0044] Further, if Figure 2 As shown, the connector 2 is located in the axial direction of the disk body 1 (e.g., Figure 2 On one side (as shown in the first direction), the connector 2 connects the disc body 1 to the axle of the vehicle, ensuring that the disc body 1 can be securely mounted on the wheel. Through the connection of the connector 2, the disc body 1 can rotate with the wheel and generate braking force by rubbing against the brake pads when braking is required.

[0045] Furthermore, such as Figure 2 and Figure 7 As shown, along the axial direction of the disc body 1, an annular gasket 3 is disposed between the head 2 and the disc body 1. Along the axial direction of the disc body 1, the first fastener 4 passes through the head 2, the annular gasket 3 and the disc body 1 in sequence to connect the head 2, the annular gasket 3 and the disc body 1.

[0046] Understandably, adding an annular shim 3 between the clutch 2 and the disc body 1 creates axial constraint on the clutch 2, making its position more reliable. Simultaneously, during extreme braking of the brake disc assembly 100, the temperature of the disc body 1 may reach over 1000℃. The annular shim 3 provides a larger contact area between the clutch 2 and the disc body 1, allowing for better heat transfer from the disc body 1 to the clutch 2 during braking. This more uniform heat transfer from the disc body 1 to the clutch 2 avoids thermal stress concentration and axial runout, thus improving the overall NVH (Noise, Vibration, and Harshness) of the vehicle. Furthermore, the surface contact between the annular shim 3 and the disc body 1 helps stabilize the end runout of the disc body 1, preventing poor brake disc end runout consistency and further improving the overall NVH.

[0047] like Figure 1 and Figure 11 As shown, multiple first fasteners 4 are spaced apart along the circumferential direction of the head 2, which can connect the head 2, the annular gasket 3 and the disc body 1 at multiple points in the circumferential direction of the head 2, making the connection between the head 2, the annular gasket 3 and the disc body 1 more reliable, avoiding loosening of the brake disc assembly 100, and helping to improve the NVH of the whole vehicle.

[0048] In addition, a single annular gasket 3 can be adapted to multiple first fasteners 4, which can reduce the number of parts during the assembly of the brake disc assembly 100, reduce the assembly time of the brake disc assembly 100, and reduce the assembly cost of the brake disc assembly 100.

[0049] According to the embodiment of the present invention, the brake disc assembly 100, by placing the annular gasket 3 between the head 2 and the disc body 1 along the axial direction of the disc body 1, and by having the first fastener 4 pass through and connect the head 2, the annular gasket 3 and the disc body 1 in sequence, can form an axial constraint in the axial direction of the head 2, making the position of the head 2 more reliable. At the same time, the connection between the annular gasket 3 and the disc body 1 is in a surface contact state, which is conducive to the stability of the end runout of the disc body 1, and makes the end runout consistency of the brake disc assembly 100 better. The annular gasket 3 can make the contact area between the head 2 and the disc body 1 larger. When the brake disc assembly 100 brakes, the heat generated by the disc body 1 can be better transferred to the head 2. The process of the head 2 receiving the high temperature of the disc body 1 is more uniform, which can avoid the thermal stress concentration of the disc body 1 and the axial runout, which is beneficial to improving the NVH of the whole vehicle.

[0050] In this embodiment, the disc body 1 is a carbon ceramic disc. When exposed to high-temperature braking environments exceeding 200°C, the carbon ceramic disc will not crack, thermally expand, or fade; instead, its coefficient of friction will increase, resulting in superior performance during continuous braking on steep slopes. Furthermore, even with increased operating temperature, the coefficient of friction of the carbon ceramic disc will not decrease, ensuring stable braking performance. The material of the connector 2 can be selected from stainless steel, aluminum alloy, and titanium alloys, depending on actual strength, lightweighting, and cost requirements, to meet different application needs.

[0051] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the annular gasket 3 includes a gasket body 31 and multiple elastic devices 32. The first fastener 4 passes through the gasket body 31. The elastic devices 32 are located on the side of the gasket body 31 near the disc body 1. At least two adjacent first fasteners 4 are provided with elastic devices 32. During the use of the brake disc assembly 100, the disc body 1 and the head 2 may expand in the axial direction after being subjected to high braking temperature. The elastic devices 32 can absorb the deformation of the disc body 1 and the head 2 to a certain extent, avoid stress concentration at the connection of the first fasteners 4, and prevent the first fasteners 4 from loosening, thereby ensuring the safety and stability of the overall structure of the brake disc assembly 100.

[0052] like Figure 7 As shown, the gasket body 31 and the disc body 1 are spaced apart along the axial direction of the disc body 1. There is a gap between the gasket body 31 and the disc body 1. The gap can prevent some of the heat of the disc body 1 from being transferred to the head 2, so as to avoid the head 2 from overheating and causing the head 2 to malfunction (the melting point of a conventional aluminum alloy head 2 is around 660℃).

[0053] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the gasket body 31 has a mounting groove 311 on the side near the disc body 1. The elastic device 32 is disposed in the mounting groove 311. After the disc body 1 and the head 2 expand, the gap between the end faces of the disc body 1 and the head 2 near each other decreases along the axial direction of the disc body 1. The mounting groove 311 can provide more deformation space for the elastic device 32, improving the effect of the elastic device 32 in absorbing the deformation generated by the disc body 1 and the head 2. The elastic device 32 includes two elastic elements 321 symmetrically arranged along the circumferential direction of the gasket body 31. The two elastic elements 321 are spaced apart along the circumferential direction of the gasket body 31. The gap between the two elastic elements 321 can absorb the deformation of the elastic elements 321, ensuring the deformation effect of the elastic device 32.

[0054] Furthermore, the elastic element 321 is a leaf spring, which has functions such as vibration damping and clamping. This facilitates the absorption of deformation generated by the disc body 1 and the head 2 by the elastic device 32, avoids stress concentration at the connection of the first fastener 4, and prevents the first fastener 4 from loosening, thereby ensuring the safety and stability of the overall structure of the brake disc assembly 100.

[0055] Meanwhile, the leaf spring is in surface contact with the disc body during operation. Compared with the traditional line contact elastic element 321, it is more conducive to the end jump stability of the disc body 1. In addition, the pad body 31 makes the heat transferred from the disc body 1 to the head 2 more even. Therefore, it can also reduce the risk of the head 2 deforming due to uneven heating, which would lead to the deterioration of the end jump of the disc body 1 and thus affect the NVH and safety of the whole vehicle.

[0056] In some embodiments of this utility model, such as Figure 1 , Figure 5 and Figure 6 As shown, the first fastener 4 includes a connecting sleeve 41 and a connecting bolt 42. Along the axial direction of the disc body 1, the connecting sleeve 41 passes sequentially through the head 2, the annular washer 3, and the disc body 1. The connecting bolt 42 is located at the end of the connecting sleeve 41 furthest from the head 2 in the axial direction. The connecting bolt 42 and the connecting sleeve 41 have a tight fit and a large preload, ensuring a tight connection between them and preventing loosening. Furthermore, the connecting sleeve 41 and the connecting bolt 42 have high rigidity and are not prone to deformation after connection, further improving the stability of the connection between the connecting bolt 42 and the connecting sleeve 41, and enhancing the stability of the connection between the head 2, the annular washer 3, and the disc body 1.

[0057] Furthermore, in this embodiment, such as Figure 5 , Figure 6 and Figure 7As shown, the axial end of the connecting sleeve 41 is provided with an internal thread 414, and the connecting bolt 42 has a stud 421 extending out. The stud 421 and the internal thread 414 are threaded together. The connection method of the connecting sleeve 41 and the connecting bolt 42 has good disassembly convenience. The connection can be easily disassembled by rotating the connecting sleeve 41 or the connecting bolt 42 without damaging the head 2, the annular washer 3 and the disc body 1. It is also easy to inspect and replace the head 2, the annular washer 3 and the disc body 1.

[0058] In this embodiment, an anti-loosening washer can be added between the connecting bolt 42 and the connecting sleeve 41 to increase the connection reliability of the connecting sleeve 41 and the connecting bolt 42.

[0059] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, a limiting notch 21 is provided on the outer peripheral wall of the connector 2. The limiting notch 21 penetrates the connector 2 along the axial direction, providing space for the connecting sleeve 41 to pass through. The side of the limiting notch 21 closest to the outer peripheral wall of the connector 2 is open, allowing the connecting sleeve 41 to be assembled with the connector 2 along the axial or radial direction. Figure 4 and Figure 5 As shown, the connecting sleeve 41 includes a tube body 411 and a positioning block 412. Along the axial direction of the tube body 411, the tube body 411 passes through the annular gasket 3 and the disc body 1. The positioning block 412 is located at one end of the tube body 411 in the axial direction and passes through the limiting notch 21. The positioning block 412 can realize the assembly positioning of the connecting sleeve 41 and the head 2, making the assembly of the connecting sleeve 41 and the head 2 simpler and more reliable.

[0060] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, a limiting groove 22 is provided on the axial end face of the coupling 2. The side of the limiting groove 22 near the outer peripheral wall of the coupling 2 is open. A limiting notch 21 is provided on the bottom wall of the limiting groove 22. A limiting protrusion 413 is provided at the end of the positioning block 412 away from the tube body 411. The limiting protrusion 413 is located in the limiting groove 22. At this time, the connection between the connecting sleeve 41 and the coupling 2 includes two limiting actions: the positioning block 412 and the limiting notch 21, and the limiting protrusion 413 and the limiting groove 22. This can further strengthen the assembly positioning of the connecting sleeve 41 and the coupling 2, making the assembly of the connecting sleeve 41 and the coupling 2 simpler and more reliable. This makes the connection between the coupling 2, the annular gasket 3 and the disc body 1 more reliable, preventing the brake disc assembly 100 from loosening and improving the NVH of the whole vehicle.

[0061] In some embodiments of this utility model, such as Figure 4 and Figure 5As shown, the positioning block 412 has a first mating surface 4121 that mates with the bottom wall of the limiting notch 21 and a second mating surface 4122 that mates with the side wall of the limiting notch 21. The bottom wall of the limiting notch 21 is in contact with the first mating surface 4121, and the side wall of the limiting notch 21 is in contact with the second mating surface 4122. It can be understood that since both the bottom wall and the side wall of the limiting notch 21 are in contact with the positioning block 412, the positioning block 412 will not rotate relative to the limiting notch 21, and the connecting sleeve 41 will not rotate relative to the head 2. This can prevent the connecting sleeve 41 from rotating, avoid the connecting sleeve 41 from loosening, and prevent the connection between the head 2, the annular gasket 3, and the disc body 1 from failing.

[0062] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the limiting protrusion 413 is provided with a third mating surface 4131 that mates with the bottom wall of the limiting groove 22 and a fourth mating surface 4132 that mates with the side wall of the limiting groove 22. The bottom wall of the limiting groove 22 is in contact with the third mating surface 4131, and the side wall of the limiting groove 22 is in contact with the fourth mating surface 4132. It can be understood that since both the bottom wall and the side wall of the limiting groove 22 are in contact with the limiting protrusion 413, the limiting protrusion 413 will not rotate relative to the limiting groove 22, and the connecting sleeve 41 will not rotate relative to the head 2. This can further prevent the connecting sleeve 41 from rotating, avoid the connecting sleeve 41 from loosening, and prevent the connection between the head 2, the annular gasket 3, and the disc body 1 from failing.

[0063] In some embodiments of this utility model, such as Figure 10 As shown, the end of the disc body 1 away from the head 2 is provided with a relief groove 11, and the first fastener 4 is recessed within the relief groove 11. That is, the connecting bolt 42 is provided within the relief groove 11, and the axial end face of the connecting bolt 42 away from the head 2 is lower than the free end face of the relief groove 11. This avoids the first fastener 4 occupying too much space in the axial direction of the disc body 1, providing more installation space for other components of the brake disc assembly 100, reducing the space required when the brake disc assembly 100 is installed on the vehicle, and increasing the arrangeability of the brake disc assembly 100.

[0064] This utility model also proposes a vehicle having the brake disc assembly 100 of the above embodiments.

[0065] The vehicle according to an embodiment of the present invention includes the brake disc assembly 100 described above.

[0066] According to the vehicle of this utility model embodiment, by providing the above-mentioned brake disc assembly 100, by placing the annular gasket 3 between the head 2 and the disc body 1 along the axial direction of the disc body 1, and by having the first fastener 4 pass through and connect the head 2, the annular gasket 3 and the disc body 1 in sequence, an axial constraint can be formed in the axial direction of the head 2, making the position of the head 2 more reliable. At the same time, the connection between the annular gasket 3 and the disc body 1 is in a surface contact state, which is conducive to the stability of the end runout of the disc body 1, and makes the end runout consistency of the brake disc assembly 100 better. The annular gasket 3 can make the contact area between the head 2 and the disc body 1 larger. When the brake disc assembly 100 brakes, the heat generated by the disc body 1 can be better transferred to the head 2. The process of the head 2 receiving the high temperature of the disc body 1 is more uniform, which can avoid the thermal stress concentration of the disc body 1 and the axial runout, which is beneficial to improving the NVH of the whole vehicle.
