Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to a brake disc structure with anti-tensile force type. Background Art

[0002] An automotive brake disc is an important component of the braking system. By clamping the brake disc with a brake caliper to generate braking force, it can achieve the function of decelerating or stopping. Therefore, the performance of the brake disc is one of the key performances affecting vehicle safety. In the process of high-speed operation and frequent braking of the traditional brake disc structure, problems such as deformation, cracks, and even fractures often occur due to the huge thermal stress and mechanical stress, seriously affecting driving safety and the reliability of the braking system.

However, this type of brake drum is designed in a circular ring shape and has poor anti-tensile force performance. When bearing the braking force transmitted by the brake disc, it cannot effectively disperse the stress, thereby increasing the risk of local overload of the structure, resulting in deformation and fracture of the brake drum, reducing the service life of the structure, and causing potential safety hazards due to component damage.

[0019] Compared with the existing technology, the utility model has the following advantages:

[0020] 1. The utility model combines a brake disc, a brake drum, a connecting component and a coupling head.

Specific implementation mode

[0031] The following combines the drawings and embodiments to further describe in detail the specific implementation mode of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0032] As Figures 1 to 5As shown, a tension-resistant brake disc structure includes a brake disc 1, a brake drum 2, a connecting assembly 3 and a joint 4 adapted to fit tightly against the bottom surface of the brake disc 1; wherein the brake disc 1 is the main part of the brake drum structure, and the brake disc 1 is made of high-strength alloy material, and has good thermal stability and wear resistance. The brake drum 2 is a truncated cone ring structure; the outer wall of the bottom end of the brake drum 2 is close to the inner wall of the bottom end of the brake disc 1; specifically, the bottom end of the brake drum 2 has an outer convex ring edge 22 close to the inner wall of the bottom end of the brake disc 1. The brake drum 2 adopts an innovative truncated cone ring structure design. Compared with the traditional annular brake drum 2, the truncated cone ring brake drum 2 can more effectively disperse stress and reduce local stress concentration when subjected to pressure from the brake pad, thereby significantly improving the tension resistance of the brake drum. The outer wall of the bottom end of the brake drum 2 is in close contact with the inner wall of the bottom end of the brake disc 1, specifically, the outer convex ring edge 22 is in close contact with the inner wall of the bottom end of the brake disc 1, ensuring a close fit between the two without any gap, further enhancing the overall stability of the structure. The connecting assembly 3 includes a connecting branch 31, a locking screw sleeve 32 and a bolt 33. Among them, a plurality of connecting branches 31 arranged around the central axis of the brake disc 1 are provided on the inner wall of the bottom end of the brake disc 1; the key design of the brake disc 1 is that a plurality of connecting branches 31 evenly arranged around the central axis of the brake disc 1 are provided on the inner wall of the bottom end, and these connecting branches 31 not only enhance the structural strength of the brake disc 1, but also provide a stable installation foundation for the subsequent installation of the brake drum 2. The joint head 4 is provided with a plurality of positioning notches 41 respectively adapted to be inserted and installed with the locking screw sleeve 32 at the position corresponding to each of the connecting branches 31; the locking screw sleeve 32 is adapted to be inserted and inserted through the positioning notches 41 and is inserted and connected with the brake disc 1; the bolt 33 is connected with the brake drum 2 through the locking screw sleeve 32. Each connecting branch 31 position on the brake disc 1 corresponds to a positioning notch 41 on the joint head 4, and these positioning notches 41 are precisely designed to ensure that the locking screw sleeve 32 can be inserted and connected accurately. One end of the locking screw sleeve 32 is tightly matched with the positioning notch 41, and the other end is inserted and connected with the brake disc 1, so that the bolt 33 is connected with the brake drum 2 through the locking screw sleeve 32, so that the brake disc 1, the brake drum 2, the connecting assembly 3 and the joint head 4 form a stable connection structure. This connection method not only simplifies the installation steps, but also greatly improves the reliability and durability of the connection.

[0033] The tension-resistant brake disc structure is designed to be a truncated cone ring structure by arranging a brake disc 1, a brake drum 2, a connecting assembly 3 and a joint 4. The brake drum 2 is designed to be a truncated cone ring structure, which is narrow at the top and wide at the bottom. The outer wall of the bottom end of the brake drum 2 is close to the inner wall of the bottom end of the brake disc 1, and has triangular stability. Then, the locking screw sleeve 32 is adapted and inserted through the positioning recess 41 to be adapted and inserted and connected with the brake disc 1. Then, the bolt 33 is used to pass through the locking screw sleeve 32 in sequence and connect with the brake drum 2, so that the brake disc 1, the brake drum 2 and the joint 4 are stably connected to form a whole, and the structure is stable and connected reliably. Compared with the traditional circular brake drum 2, the truncated cone ring brake drum 2 designed in this way, firstly, its bottom diameter is larger than the top design, so that the brake drum 2 can more effectively disperse stress when bearing the braking force transmitted by the brake disc 1, and reduce the risk of local overload. Secondly, the gradual change of the truncated cone ring shape enhances the overall rigidity of the structure, and even under extreme braking conditions, it can maintain a stable shape and is not easy to deform. Most importantly, this design significantly improves the tension resistance of the brake drum 2, thereby improving its ability to resist deformation and fracture, which is conducive to extending the service life of the structure and reducing safety hazards caused by component damage. At the same time, the brake disc 1, the brake drum 2 and the joint 4 are connected together through the connecting component 3, and there is a gradient space between the brake disc 1 and the brake drum 2, which has a good heat dissipation effect.

[0034] Preferably, a plurality of the connecting branches 31 are connected to form an annular plate-like structure; the brake disc 1 and the annular plate-like structure are integrally formed. The connection relationship between the connecting branch 31 and the brake disc 1 is designed in this way, and the structural connection is stable and reliable, which significantly improves the tension resistance of the brake drum structure and is not prone to breakage or deformation.

[0035] In order to further improve the connection stability of the structure, so as to better improve the tensile strength of the brake drum structure, and not prone to breakage and deformation. The connection between the two adjacent connecting branches 31 has a positioning recess 5 opened toward the central axis of the brake disc 1; the bottom surface of the brake drum 2 is provided with positioning protrusions 6 that are the same in number and one-to-one corresponding to the positioning recess 5; the positioning protrusions 6 are inserted through the positioning recess 5 and abut against the joint 4. In this way, the positioning recess 5 and the positioning protrusion 6 are designed, and the same number of positioning recesses 5 and positioning protrusions 6 are designed, and the positioning protrusions 6 are inserted through the positioning recess 5 and abut against the joint 4, so as to enhance the connection stability of the brake disc 1, the brake drum 2 and the joint 4, and the structure is more compact and reliable, and can maintain a stable shape even under extreme braking conditions, and is not prone to deformation. Most importantly, this design significantly improves the overall tensile strength of the brake drum structure, thereby improving its ability to resist deformation and breakage, which is conducive to extending the service life of the structure and reducing safety hazards caused by component damage.

[0036] In order to simplify the design and production and make the structural connection more stable and reliable, the positioning notch 5 is a U-shaped notch, a C-shaped notch or a V-shaped notch. In this embodiment, the positioning notch 5 is preferably a U-shaped notch. The corresponding positioning protrusion 6 will also be designed with a corresponding shape, so that the structural connection is more stable and reliable, and the tensile strength performance is better.

[0037] In this embodiment, the locking screw sleeve 32 includes a cylindrical screw sleeve body 321, a square column screw sleeve body 322 and a locking pressure plate 323; the cylindrical screw sleeve body 321, the square column screw sleeve body 322 and the locking pressure plate 323 are sequentially connected from top to bottom to form a whole; the locking screw sleeve 32 has a locking screw hole 324 that is compatible with the bolt 33 and passes through the cylindrical screw sleeve body, the square column screw sleeve body 322 and the locking pressure plate 323; the connecting branch 31 has a locking screw hole 324 that is compatible with the cylindrical screw sleeve body The first mounting hole 311 adapted to the brake drum 2 is provided on the bottom surface thereof with a second mounting hole 21 adapted to the bolt 33; the locking pressure plate 323 is in contact with the bottom surface of the joint 4, and the square column screw sleeve body 322 is adapted to be embedded in the positioning recess 41; the cylindrical screw sleeve body 321 is adapted to be embedded in the first mounting hole 311; the bolt 33 is adapted to pass through the locking screw hole 324 and is threadedly connected with the second mounting hole 21. First, the cylindrical screw sleeve body 321, the square column screw sleeve body 322 and the locking pressure plate 323 are connected in sequence from top to bottom to form a tight whole. This design not only simplifies the assembly process, reduces the looseness and errors that may be caused by the assembly of multiple parts, but also fundamentally improves the stability of the entire connection system. The integrated structure can show stronger resistance and durability when facing complex working conditions such as vibration and impact, ensuring the long-term stable operation of the connection components. Secondly, the design of the shape and connection relationship of the cylindrical screw sleeve 321, the square column screw sleeve 322 and the locking pressure plate 323 makes it difficult for the structure to loosen or rotate; the connection between the joint 4, the brake disc 1 and the brake drum 2 is more stable, and the entire structure can maintain a good working state when subjected to various external forces, effectively preventing the structure from loosening; finally, in order to make the structural connection more accurate and reliable, the first mounting hole 311 of the connecting branch 31 is perfectly matched with the cylindrical screw sleeve 321, so that fast positioning can be achieved without tedious adjustments during the installation process. At the same time, the design of the square column screw sleeve 322 adapter card embedded in the positioning recess 41 improves the accuracy of structural positioning.

[0038] In this embodiment, the brake disc 1 includes an upper annular body 11, a lower annular body 12 and a connecting reinforcement rib 13; the upper annular body 11 and the lower annular body 12 are arranged at intervals corresponding to each other and connected by the connecting reinforcement rib 13; a plurality of connecting reinforcement ribs 13 are evenly arranged between the upper annular body 11 and the lower annular body 12 around the central axis of the upper annular body 11; the upper annular body 11, the lower annular body 12, and two adjacent connecting reinforcement ribs 13 form a heat dissipation channel 14. The brake disc 1 is formed by combining the upper annular body 11, the lower annular body 12 and the connecting reinforcement rib 13. The plurality of connecting reinforcement ribs 13 are not only evenly distributed between the upper annular body 11 and the lower annular body 12 to form a stable supporting structure, but also optimize the overall force distribution through precise layout. This design enables the brake disc 1 to maintain extremely high rigidity and stability, reduce deformation, and improve braking response speed and accuracy when subjected to huge braking force. At the same time, the presence of the connecting reinforcement ribs 13 also enhances the anti-fatigue performance of the brake disc 1, and ensures the reliable operation of the brake system even under harsh road conditions or frequent braking conditions. On the other hand, the several heat dissipation channels 14 on the brake disc 1 are like miniature heat dissipation channels. When the brake pads and the brake disc 1 generate a lot of heat due to friction, the hot air can be quickly discharged through these channels, effectively reducing the temperature of the brake disc 1, achieving a good heat dissipation effect, and thus better improving the safety performance of the structure.

[0039] Preferably, the upper surface of the upper annular body 11 and the lower surface of the lower annular body 12 are both provided with a plurality of arc grooves 7 evenly arranged around the central axis of the brake disc 1. The plurality of arc grooves 7 on the upper surface of the upper annular body 11 and the lower surface of the lower annular body 12 can quickly discharge the powder debris on the upper surface to prevent the debris from adhering to the friction surface between the brake discs 1, causing the brake discs 1 to be scratched and affecting the braking effect. At the same time, the air flow can be accelerated to dissipate the heat generated by the friction on the brake disc 1 faster to avoid affecting the braking effect.

[0040] In summary, the embodiment of the utility model provides an anti-tension type brake disc structure, wherein the anti-tension type brake disc structure has the following advantages:

[0041] 1. Compared with the traditional circular brake drum 2, the truncated cone-shaped brake drum 2 has a larger bottom diameter than the top, which enables the brake drum 2 to more effectively disperse stress and reduce the risk of local overload when bearing the braking force transmitted by the brake disc 1. Secondly, the gradual change of the truncated cone shape enhances the overall rigidity of the structure, and it can maintain a stable shape and is not prone to deformation even under extreme braking conditions. Most importantly, this design significantly improves the tension resistance of the brake drum 2, thereby improving its ability to resist deformation and fracture, which is conducive to extending the service life of the structure and reducing safety hazards caused by component damage.

[0042] Second, the brake disc 1, the brake drum 2 and the adapter 4 are connected together through the connecting component 3. There is a gradually changing space between the brake disc 1 and the brake drum 2, and in combination with the heat dissipation channels 14 and the arc grooves 7, the anti-tensile brake disc structure has an efficient heat dissipation effect.

[0043] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present application.
