Description

Technical Field

[0001] This utility model relates to the field of vehicle braking technology, specifically to an ABS braking system for all-terrain vehicles. Background Technology

[0002] In existing motorcycle braking systems, the sensor ring and brake disc are typically connected as two separate components. This design has several drawbacks. First, the connection structure occupies a significant amount of space, which is particularly unreasonable in the limited space of a motorcycle, restricting the installation location and space optimization of other components and affecting the overall compact design of the motorcycle. Second, over long-term use, due to vibrations during motorcycle operation and the impact force generated during braking, the connection between the sensor ring and the brake disc is prone to loosening. Once the connection becomes loose, it will not only affect the accurate transmission of braking signals and reduce the reliability of the braking system, but may also cause the brake disc to wobble at high speeds, thus affecting braking performance and potentially leading to brake failure and other serious safety hazards, posing a significant threat to motorcycle driving safety.

[0003] Chinese Patent Publication No. CN112065897A, published on December 11, 2020, discloses a Chinese patent entitled "A Brake Disc," which includes a coaxially arranged gear ring and a brake disc. The gear ring has a connecting portion that fits against one axial end of the brake disc. Each connecting portion has a first through hole, and the brake disc has a second through hole. The number and position of the second through holes correspond one-to-one with the first through holes. Rivets are also provided on the connecting portion. The gear ring and brake disc are riveted together by the rivets passing through the first and corresponding second through holes. This structure features a separate gear ring and brake disc with an intermediate connecting component, increasing space requirements and cost. Utility Model Content

[0004] This utility model provides an ABS braking system for all-terrain vehicles. By setting a toothed brake disc, the sensing toothed ring is combined with the brake disc, saving space, reducing costs, and improving safety.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an all-terrain vehicle ABS braking system, including a gear ring brake disc, a brake caliper is provided on one side of the gear ring brake disc, a caliper fixing bracket is provided on the top, and the caliper fixing bracket is connected to the brake caliper; a first mounting hole is provided in the center of the gear ring brake disc, a sensing ring is provided around the first mounting hole, a plurality of sensing holes are provided on the sensing ring, a brake ring is provided around the sensing ring, and a plurality of heat dissipation holes are provided on the brake ring.

[0006] Preferably, a plurality of second mounting holes are provided between the first mounting hole and the sensing ring. The first and second mounting holes are circular. The circular mounting hole design makes installation more convenient and quick, and can evenly distribute the force, improve the installation stability of the gear ring brake disc, avoid stress concentration problems caused by irregular shape of the mounting holes, and thus extend the service life of the gear ring brake disc.

[0007] Preferably, a plurality of second mounting holes are evenly arranged circumferentially around the first mounting hole, and the diameter of the first mounting hole is larger than that of the second mounting holes. The first mounting holes are used to fit the bearing, and the second mounting holes are used to fix the gear ring brake disc. The evenly arranged second mounting holes ensure that the gear ring brake disc is subjected to balanced force after installation, effectively preventing it from shifting or shaking during use. At the same time, the design that the diameter of the first mounting hole is larger than that of the second mounting hole makes the bearing fitting more secure, further enhancing the overall stability of the braking system and improving the accuracy and reliability of braking.

[0008] Preferably, the sensing holes are rectangular and evenly circumferentially arranged around the center point of the geared brake disc. The rectangular sensing hole design ensures the stability and accuracy of the wheel speed sensor signal during sensing, avoiding signal interference caused by irregular hole shapes. The evenly circumferentially arranged sensing holes allow the wheel speed sensor to sense the rotational speed of the geared brake disc from all directions and evenly, thereby more precisely controlling the braking force and improving the performance and safety of the braking system.

[0009] Preferably, the brake ring is positioned near the outer edge of the geared brake disc. Positioning the brake ring near the outer edge fully utilizes the outer space of the geared brake disc, increasing the diameter of the brake ring. This increases the contact area between the brake pads and the brake ring, improving friction during braking, enhancing braking performance, shortening braking distance, and improving the braking performance and safety of the all-terrain vehicle.

[0010] Preferably, the brake ring, sensing ring, and first mounting hole are arranged in the same plane. The gear ring brake disc is a single circular plate. This design makes the overall structure of the gear ring brake disc more compact and simple, facilitating manufacturing, installation, and maintenance. Arranging the brake ring, sensing ring, and first mounting hole in the same plane ensures smoother coordination between components, reduces the risk of failure due to component misalignment or non-parallelism, and improves the overall performance and reliability of the braking system.

[0011] Preferably, the caliper mounting bracket is provided with a first mounting seat and a second mounting seat, which are respectively bolted to the brake caliper. By providing the first and second mounting seats on the caliper mounting bracket and connecting them to the brake caliper using bolts, a more secure and reliable connection between the caliper mounting bracket and the brake caliper can be ensured. This connection method facilitates installation and disassembly, and can also withstand greater braking force, ensuring the stability and reliability of the braking system during long-term use, and avoiding problems such as brake failure due to loose connections.

[0012] Preferably, the caliper mounting bracket has a mounting hole on the first mounting base, and a wheel speed sensor is installed within the mounting hole. Placing the wheel speed sensor within the mounting hole on the first mounting base of the caliper mounting bracket provides a stable mounting position for the wheel speed sensor, making it less susceptible to external interference and damage during operation. This design improves the measurement accuracy and stability of the wheel speed sensor, thereby more accurately monitoring the wheel's rotational speed, providing a more reliable signal for the ABS braking system control, and enhancing the safety and reliability of the braking system.

[0013] Preferably, the wheel speed sensor is positioned above the sensing hole, and a protective cover is provided above the geared brake disc. The wheel speed sensor and the sensing hole do not contact each other. The protective cover is shaped to fit the geared ring, has an opening at the bottom, and a notch at the brake caliper to allow space for the caliper. Its size is larger than the geared brake disc. Positioning the wheel speed sensor above the sensing hole without contacting it avoids sensor damage and signal interference caused by contact friction, ensuring stable operation of the wheel speed sensor. The protective cover effectively prevents impurities such as mud and stones from entering the sensing hole and wheel speed sensor area, protecting the wheel speed sensor and sensing gear from external environmental influences and extending their service life. Simultaneously, the notch design of the protective cover allows for fitting the brake caliper without affecting its normal operation, ensuring the overall performance and reliability of the braking system.

[0014] Preferably, a third mounting base is provided below the gear ring brake disc, and bolts pass through the second mounting hole and connect to the third mounting base. The third mounting base has several mounting posts, each corresponding to a second mounting hole. Bolts pass through the gear ring brake disc and fix it to the mounting posts. This further enhances the fixing strength and stability of the gear ring brake disc. This fixing method makes the gear ring brake disc less prone to loosening or displacement during high-speed rotation and frequent braking, improving the reliability and safety of the braking system. It also facilitates the installation and removal of the gear ring brake disc, making maintenance and replacement convenient.

[0015] Beneficial effects: This utility model combines the sensing gear ring with the brake disc to form a gear ring brake disc, which effectively saves space, reduces costs, and improves the safety of the braking system. It avoids problems such as loose connection caused by the separate connection of the sensing gear ring and the brake disc in the prior art, and enhances the reliability and stability of the braking system.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In the safety configuration of all-terrain vehicles, the braking system plays a crucial role. In traditional braking systems, the sensing ring and brake disc are independent, which not only occupies a large space but also has a high cost, and there is room for improvement in safety. The all-terrain vehicle ABS braking system provided by this utility model cleverly integrates the sensing function and braking function through the innovative design of the ring brake disc 5, achieving multiple breakthroughs in space optimization, cost reduction, and safety performance improvement.

[0024] like Figure 1 and Figure 3 As shown, the all-terrain vehicle ABS braking system of this utility model uses a geared ring brake disc 5 as its core component, and its structural design embodies in-depth consideration of functional integration and performance optimization. The geared ring brake disc 5 presents an overall circular plate structure. This simple and regular shape not only facilitates processing and manufacturing but also provides an ideal carrier for the layout of various internal functional components. On one side of the geared ring brake disc 5, the brake caliper 2 is precisely installed. As the direct actuator for realizing the braking function, the brake caliper 2 can apply pressure to the brake ring 5.5 through mechanical or hydraulic means, thereby generating friction to decelerate the wheel. Above the geared ring brake disc 5, the caliper fixing bracket 4 is connected to the brake caliper 2. The caliper fixing bracket 4 plays a role in firmly supporting the brake caliper 2, ensuring that the brake caliper 2 maintains a stable position during frequent braking operations and avoiding the impact of shaking or displacement on the braking effect.

[0025] like Figure 5 As shown, a first mounting hole 5.1 is located at the center of the geared brake disc 5. This hole plays a crucial connecting role in the entire braking system, primarily for mounting the bearing. The bearing, through its tight fit with the first mounting hole 5.1, enables relative rotation between the wheel and the brake disc, while providing stable support for the wheel's rotation. A sensing ring 5.3 surrounds the first mounting hole 5.1, and several sensing holes 5.4 are distributed on the sensing ring 5.3. These sensing holes 5.4 are rectangular and evenly arranged circumferentially around the center point of the geared brake disc 5. The design of the rectangular sensing holes 5.4 reflects profound technical considerations; compared to other shapes, the regular edges of the rectangular holes provide a stable and clear sensing signal for the wheel speed sensor 6. When the geared brake disc 5 rotates with the wheel, the wheel speed sensor 6, by sensing these evenly distributed rectangular holes, can accurately capture the rotational speed information of the brake disc and convert it into an electrical signal, which is then transmitted to the ABS control system. The ABS control system precisely controls the braking force based on these real-time wheel speed signals, preventing wheel lock-up during braking and ensuring that the all-terrain vehicle maintains good handling and safety in various complex road conditions.

[0026] like Figure 5As shown, the brake ring 5.5, which bears the main braking function, is located on the outer ring of the sensing ring 5.3. The brake ring 5.5 has several heat dissipation holes 5.6, designed to handle the large amount of heat generated by friction during braking. When the all-terrain vehicle brakes, the intense friction between the brake pads and the brake ring 5.5 causes the temperature of the brake ring 5.5 to rise sharply. If the heat cannot be dissipated in time, it will not only reduce braking performance but may also lead to serious safety problems such as brake failure. The presence of the heat dissipation holes 5.6 effectively promotes airflow, accelerates heat dissipation, and ensures that the brake ring 5.5 remains within a reasonable operating temperature range during prolonged, high-intensity braking. Simultaneously, the brake ring 5.5 is positioned near the outer edge of the toothed brake disc 5, a layout that fully utilizes the outer space of the brake disc. Placing the brake ring 5.5 on the outer side increases its diameter, thereby increasing the contact area between the brake pads and the brake ring 5.5. A larger contact area means that under the same pressure, greater friction can be generated, which significantly enhances braking effect, shortens braking distance, and further improves the braking performance and safety of all-terrain vehicles.

[0027] like Figure 5 As shown, in the design of the mounting holes, several second mounting holes 5.2 are provided between the first mounting hole 5.1 and the sensing ring 5.3. These second mounting holes 5.2 are also circular and are evenly arranged around the first mounting hole 5.1. The design of circular mounting holes has many advantages. On the one hand, circular holes make it easier and faster to align and tighten bolts or other connecting parts. On the other hand, the circular structure allows for even distribution of force, avoiding stress concentration problems caused by irregular shapes of mounting holes. Stress concentration often leads to premature fatigue, deformation, or even breakage of components during use. Circular mounting holes effectively solve this problem, thereby extending the service life of the gear ring brake disc 5. In addition, the diameter of the first mounting hole 5.1 is larger than that of the second mounting holes 5.2. This difference in size is designed to meet different installation requirements. The larger diameter of the first mounting hole 5.1 can accommodate the size of the bearing, ensuring a stable bearing connection and providing reliable support for wheel rotation; while the second mounting holes 5.2 are used to fix the gear ring brake disc 5, tightly connecting it to components such as wheels or axles. The circumferentially evenly arranged second mounting holes 5.2 ensure that the gear ring brake disc 5 is subjected to balanced force after installation, preventing it from shifting or shaking during high-speed rotation or frequent braking, further enhancing the overall stability of the braking system and making braking operation more precise and reliable.

[0028] like Figure 3 , Figure 4 and Figure 5As shown, the brake ring 5.5, the sensing ring 5.3, and the first mounting hole 5.1 are all located in the same plane. This design makes the structure of the gear ring brake disc 5 more compact and simple. During manufacturing, the layout of components in the same plane facilitates integrated machining processes, reducing the complexity and errors in the assembly process. Installation and maintenance are also more convenient and faster, as workers do not need to spend a lot of effort adjusting the parallelism or positional relationships between components. The fact that all components are in the same plane ensures their synergy during operation, avoiding the risk of malfunctions such as abnormal signal transmission and uneven braking force caused by component misalignment or non-parallelism, thus improving the overall performance and reliability of the braking system.

[0029] This utility model's all-terrain vehicle ABS braking system, through the innovative design of the gear ring brake disc 5, organically combines sensing and braking functions. While saving space and reducing costs, it significantly improves the safety and reliability of the braking system. From the optimized force distribution of the circular mounting holes to the signal stabilization design of the rectangular sensing holes 5.4; from the rational layout of the brake rings 5.5 to enhance braking performance, to the compact structure with all components arranged on the same plane, every design detail is closely focused on improving braking system performance. This provides a solid guarantee for the safe driving of all-terrain vehicles in complex and varied terrain environments, possessing significant practical value and broad application prospects.

[0030] like Figure 3 As shown, the caliper mounting bracket 4 serves as a crucial hub connecting the brake caliper 2 to other components, and its structural design directly impacts the stability of the braking system. The caliper mounting bracket 4 features a first mounting seat 4.1 and a second mounting seat 4.2, which act as robust "bridges," bearing the heavy responsibility of connecting to the brake caliper 2. Both the first mounting seat 4.1 and the second mounting seat 4.2 are made of high-strength metal, and their surfaces are finely machined to ensure a tight fit with the brake caliper 2. Both are connected to the brake caliper 2 via bolts. This bolted connection is not a simple fixation but rather the result of precise calculations and testing of bolt specifications and tightening torque. During installation, operators use specialized tools to tighten the bolts to the predetermined torque, establishing a secure mechanical connection between the caliper mounting bracket 4 and the brake caliper 2. This connection method offers dual advantages: Firstly, in daily use, it can withstand the enormous braking force generated during braking. Even with frequent braking by the all-terrain vehicle in complex road conditions, the connection remains secure and does not shift, maintaining the stable operation of the braking system. Secondly, when maintenance or repair of the braking system is required, the brake caliper can be easily removed simply by unscrewing the bolts with a tool, making the operation convenient and efficient, significantly reducing maintenance time and labor costs. Compared to other connection methods, bolted connections offer higher reliability, effectively preventing serious safety hazards such as brake failure caused by loose connections, thus laying a solid foundation for the safe operation of all-terrain vehicles.

[0031] like Figure 2 and Figure 4 As shown, this invention also features an ingenious design in the protection of the wheel speed sensor 6 and the sensing gear ring. The wheel speed sensor 6 is positioned above the sensing hole 5.4, with a certain gap between them to avoid direct contact. This non-contact design completely eliminates problems such as sensor wear and signal interference caused by friction between the sensor and the sensing hole 5.4. Even under conditions of prolonged high-speed driving or frequent braking in an all-terrain vehicle, the wheel speed sensor 6 can maintain good working condition and stably output accurate wheel speed signals. Meanwhile, the protective cover 1 installed above the gear ring brake disc 5 acts like a robust "armor," providing all-around protection for the sensor and the sensing gear ring. The protective cover 1 is made of high-strength, wear-resistant material, and its shape is highly compatible with the gear ring brake disc 5, allowing it to tightly cover the top of the gear ring brake disc 5. The bottom opening of the protective cover 1 ensures normal wheel rotation space while preventing impurities such as mud and rainwater from entering from the bottom. The specially designed notch at the brake caliper 2 provides sufficient room for movement, ensuring that the brake caliper 2 can open and close freely during braking without affecting its normal operation. When the all-terrain vehicle traverses muddy, sandy, or other harsh environments, the protective cover 1 effectively blocks the intrusion of mud, sand, stones, and other foreign objects, preventing damage to the wheel speed sensor 6 and the sensing gear ring, significantly extending the service life of related components, and ensuring the overall stable performance of the braking system.

[0032] like Figure 1 As shown, to further enhance the fixing strength of the gear ring brake disc 5, this utility model provides a third fixing seat 3 below the gear ring brake disc 5. The third fixing seat 3 is made of thick and sturdy metal, and its structural design fully considers mechanical principles and actual usage requirements. Several mounting posts 3.1 are distributed on the third fixing seat 3, and the position and size of these mounting posts 3.1 correspond one-to-one with the second mounting holes 5.2 on the gear ring brake disc 5. During installation, bolts are passed through the second mounting holes 5.2 of the gear ring brake disc 5 and the mounting posts 3.1 of the third fixing seat 3 in sequence, and then tightened with nuts. This fixing method forms a stable structure with multi-point support, which allows the gear ring brake disc 5 to evenly distribute the force it bears during high-speed driving and frequent braking of all-terrain vehicles, making it less prone to loosening or displacement. Whether it is the severe bumps when the vehicle is driving on rugged mountain roads or the huge impact force generated during emergency braking, the combination of the third fixing seat 3 and the bolts can firmly fix the gear ring brake disc 5, ensuring that the braking system always maintains reliable operation. At the same time, this fixing method is also very convenient for maintenance. Staff only need to unscrew the bolts to quickly disassemble the gear ring brake disc 5 for inspection, repair or replacement, which effectively improves the maintainability of the braking system and reduces maintenance costs.

[0033] This invention cleverly combines the sensor gear ring and brake disc to form an integrated gear ring brake disc structure. This innovative design significantly optimizes space utilization, effectively saving valuable vehicle space and providing greater flexibility for the installation of other components and overall layout of the all-terrain vehicle. Simultaneously, the integrated structure greatly reduces the number of parts, lowering production and maintenance costs and improving economic efficiency. In terms of safety, this invention excels. It completely solves the problem of loose connection caused by the separate connection between the sensor gear ring and brake disc in existing technologies. This looseness can easily lead to inaccurate brake signal transmission and unstable braking performance under long-term use and complex road conditions, posing safety hazards. The integrated design of this invention makes the connection between the sensor gear ring and brake disc more robust, enhancing the overall stability of the braking system and ensuring accurate brake signal transmission and reliable braking performance.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
