Description

Technical Field

[0001] This invention relates to the field of motorcycle disc brake technology, and in particular to a motorcycle disc brake assembly. Background Technology

[0002] Motorcycle disc brake assemblies are primarily responsible for converting the rider's braking actions into braking force, slowing or stopping the vehicle. They are devices that use a hydraulic system to drive brake pads to clamp the brake disc, achieving braking. Their core components include the brake disc, caliper, brake pads, and hydraulic pump. They offer advantages such as high braking efficiency, good heat dissipation, easy maintenance, and strong water drainage, and are widely used in modern motorcycles. However, when using disc brake assemblies, the brake disc is exposed to the air, and some designs have heat dissipation holes, which can quickly dissipate heat and reduce heat fade. During riding, the exposed brake disc often accumulates dust or gravel, especially on muddy roads. Mud adhering to the brake disc can easily lead to brake failure. Furthermore, foreign objects adhering to the brake disc can cause wear on the brake disc surface during braking, affecting its lifespan. On long-distance rides, especially downhill, frequent braking can cause excessive heat to accumulate on the brake disc, leading to heat fade, affecting braking performance, and posing a risk of brake failure. Summary of the Invention

[0003] To overcome the technical defects of the existing technology, the present invention provides a motorcycle disc brake assembly that reduces the adhesion of foreign objects to the surface of the brake disc and improves the cooling effect of the brake disc, thereby improving braking stability.

[0004] The technical solution adopted in this invention is: a motorcycle disc brake assembly, including a brake disc assembly and a caliper assembly. One end of the brake disc assembly is located inside the caliper assembly. The brake disc assembly is mounted on the wheel hub of an external motorcycle, and the caliper assembly is mounted on the frame of the external motorcycle. The brake disc assembly includes a disc body, and an annular notch is formed inside the disc body. A water spray ring is rotatably mounted inside the notch. A connecting rigid pipe is fixedly mounted on one end of the water spray ring, and one end of the connecting rigid pipe is threadedly connected to the caliper assembly. The caliper assembly consists of a fixed caliper mechanism and a movable caliper mechanism. The movable caliper mechanism is slidably engaged with the fixed caliper mechanism. Grooves are formed on opposite sides of the fixed caliper mechanism and the movable caliper mechanism. A first brake pad is fixedly mounted inside the groove on the movable caliper mechanism, and a second brake pad is slidably engaged inside the groove on the fixed caliper mechanism. A cleaning component for cleaning the brake disc assembly is obliquely inserted into the upper end of the fixed caliper mechanism. During use, the assembly is performed first, so that one side of the disc body is... Between the fixed caliper mechanism and the movable caliper mechanism, after the brake disc assembly and the caliper assembly are installed, the cleaning component is inserted into the fixed caliper mechanism in the caliper assembly. Then, the water spray ring is rotated so that one end of the connecting rigid tube is threadedly connected to the fixed caliper mechanism in the caliper assembly, thus fixing the water spray ring and the connecting rigid tube. During riding, the disc rotates with the motorcycle tire, driving the cleaning component to clean both sides of the disc. When braking, the first brake pad moves towards the second brake pad with the movable caliper mechanism, and the second brake pad moves towards the first brake pad inside the groove, clamping the disc between the first and second brake pads to achieve braking. Simultaneously, if the motorcycle is equipped with a water supply device, the external water supply device supplies water to the connecting rigid tube and sprays it out through the water spray ring to cool the disc and improve braking stability.

[0005] Preferably, the disc body has a circular ring structure, and the inner ring of the disc body has a first mounting lug fixedly installed in a circular array. The disc body forms an I-shaped structure through the notch, and a bearing is fixedly installed inside the notch. The outer ring of the bearing is fixedly connected to the water spray ring. Water spray nozzles are obliquely opened on both sides of the outer ring of the water spray ring. A connecting nut is rotatably installed at one end of the connecting rigid tube. The first mounting lug facilitates the use of external bolts to fix the disc body to the wheel hub axle of the motorcycle for a fixed connection. The notch improves the airflow effect inside the disc body, facilitating air cooling. When cooling water is sprayed out through the obliquely opened water spray nozzles, the water flow is sprayed towards both sides inside the disc body, which facilitates the use of water tension and centrifugal force when the disc body rotates to evenly distribute the sprayed water on the disc body. The connecting nut facilitates the threaded connection between the connecting rigid tube and the fixing caliper mechanism.

[0006] Preferably, the disk body has heat dissipation holes arranged in a circumferential array. Fins are fixedly installed in a circumferential array on both sides of the inner side of the notch. Each fin has an arc-shaped structure, and the fins on both sides are symmetrically distributed. The end of the fin closest to the outer side of the disk body is bent to form an arc hook. A water passage hole is opened at the center of the arc hook on the disk body. The side of the fin away from the disk body is bent to form a baffle. The heat dissipation holes improve heat dissipation performance. By installing fins inside the notch, when the disk body rotates, the built-in fins form a turbulent shear layer, making the disk... The increased airflow velocity around the body enhances the forced convection cooling effect, facilitating air cooling and improving heat dissipation performance when the motorcycle is not equipped with a water supply device. It also reduces heat accumulation. When the motorcycle is equipped with a water supply device, the cooling water is sprayed out through the nozzles on the spray ring and, using centrifugal force, is thrown outwards from the disc. Guided by the fins, the cooling water gathers at the arc-shaped hook position, and the baffles further enhance the water gathering capacity at the arc-shaped hook position. When the gathered water volume is sufficient, it flows through the water passage holes to the outer sides of the disc for rapid cooling.

[0007] Preferably, the fixed caliper mechanism includes a fixed clamp, a second mounting ear fixedly installed on one side of the fixed clamp, and a first hydraulic cylinder fixedly installed on the outer side of the fixed clamp. The telescopic end of the first hydraulic cylinder extends into the groove of the fixed caliper mechanism and is fixedly connected to the second brake pad. A guide hole is formed on the fixed clamp on one side of the first hydraulic cylinder, and one end of the movable caliper mechanism is inserted into the guide hole. A second hydraulic cylinder is fixedly installed on one side of the fixed clamp between the two guide holes, and the telescopic end of the second hydraulic cylinder is fixedly connected to the movable caliper mechanism. The first and second hydraulic cylinders are connected by oil circuits. During installation, the second mounting ear facilitates the fixing of the caliper assembly to the frame. When braking, hydraulic oil from the external upper pump is pumped into the first and second hydraulic cylinders. The extension end of the first hydraulic cylinder extends to push the second brake pad, and the extension end of the second hydraulic cylinder extends to pull the movable caliper mechanism, causing the first brake pad to move towards the second brake pad. The first and second brake pads clamp the disc body, achieving the braking effect.

[0008] Preferably, an oil circuit connector is fixedly installed on one side of the fixing clamp, and a connecting oil pipe is fixedly installed on one side of the second cylinder. One end of the connecting oil pipe is connected to the oil circuit connector, and one end of the oil circuit connector is connected to an external brake upper pump. A water circuit connector is fixedly installed on the upper end of the fixing clamp, and one end of the connecting rigid pipe is threaded to the water circuit connector. Through the connecting oil pipe and the oil circuit connector, the first and second cylinders are easily connected to the external upper pump, allowing the upper pump to pump hydraulic oil into the first and second cylinders, causing the first and second cylinders to extend and retract. The water circuit connector is described above. The connecting rigid pipe is threadedly connected to the water circuit connector via the connecting nut. When the motorcycle is equipped with a water supply device, the external water supply device is connected to the connecting rigid pipe via the water circuit connector, facilitating water supply to the inside of the spray ring. When the motorcycle is not equipped with a water supply device, the connecting rigid pipe is threadedly connected to the water circuit connector, facilitating the fixing of the connecting rigid pipe and the spray ring, preventing the connecting rigid pipe from rotating with the disc body. After the connecting rigid pipe is installed, it limits one end of the cleaning component, preventing the cleaning component from disengaging from the fixing caliper mechanism.

[0009] Preferably, the upper end of the fixing clamp is provided with T-shaped grooves on both sides, and the two ends of the cleaning component are slidably engaged inside the grooves. The grooves facilitate quick assembly and disassembly of the cleaning component and make maintenance easier.

[0010] Preferably, the movable caliper mechanism includes a movable plate, the groove of which is formed on the movable caliper mechanism, and the first brake pad is fixedly connected to the movable plate. Guide rods are fixedly installed at both ends of one side of the movable plate. The guide rods are inserted into the guide holes and extend to one side of the fixed caliper. A connecting plate is fixedly installed between the two guide rods. The connecting plate is fixedly connected to the extension end of the second hydraulic cylinder. Through the guide rods and the connecting plate, when the second hydraulic cylinder extends or retracts, it drives the movable plate to move, thereby causing the first brake pad to move, achieving the effect of pressing or moving away from the disc.

[0011] Preferably, the cleaning component includes a gantry frame with sliders on both sides that match the slide groove. The gantry frame is slidably engaged with the slide groove via the sliders. Handles are fixedly installed on both sides of the upper end of the gantry frame. Brushes are rotatably installed on both sides of the inner side of the gantry frame. One side of the brush contacts the brake disc assembly. A first bevel gear is fixedly installed on the shaft at one end of the brush. The handles and sliders facilitate the installation of the gantry frame inside the slide groove. The brushes are driven when the disc rotates, and the disc and brushes move at a differential speed, facilitating the cleaning of dust or dirt adhering to the surface of the disc.

[0012] Preferably, a second bevel gear is rotatably mounted on both sides of the inner side of the gantry frame. The first bevel gear meshes with the second bevel gear. A rubber roller is rotatably mounted in the middle of the inner side of the gantry frame. The rubber roller contacts the outer side of the brake disc assembly. The rubber roller is linked with the second bevel gear. When the disc rotates, the rubber roller rotates, thereby driving the second bevel gear and causing the brush to rotate, thus achieving the effect of cleaning the surface of the disc.

[0013] Preferably, drive gears are fixedly installed at both ends of the rubber roller, and a differential gear is fixedly installed at one end of the second bevel gear. The differential gear meshes with the drive gear. When the rubber roller rotates, the rubber roller drives the drive gear, and through the differential gear, the rotational speed of the second bevel gear and the rubber roller changes, so that the rotational speed of the brush and the rotational speed of the disc body form a speed difference, which facilitates the brush to clean the surface of the disc body.

[0014] The beneficial effects of this invention are as follows: 1. By adopting an I-shaped disc body and installing fins inside, heat dissipation is enhanced based on aerodynamics. The built-in fin group forms a turbulent shear layer during riding, which increases the airflow velocity around the disc body by 42%, effectively enhancing the forced convection heat dissipation efficiency. In addition, water is sprayed onto the fin position through the water spray ring during braking. The centrifugal force of the disc body during rotation causes the cooling water to accumulate at the arc hook position. The water passage hole allows the cooling water to flow into both sides of the disc body for rapid cooling, reducing the temperature gradient of the disc surface, reducing heat attenuation, and significantly improving the thermal stability under continuous braking conditions.

[0015] 2. By adopting a sliding snap-fit ​​cleaning component, the cleaning component can be quickly replaced. During riding, the disc drives the cleaning component, and through the differential gear, the brush and disc move at different speeds to peel off the dust adhering to the disc surface, making it easier to clean the disc surface. This not only improves the service life of the disc but also enhances stability during braking. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-10As shown, this embodiment provides a motorcycle disc brake assembly, including a brake disc assembly 1 and a caliper assembly 2. One end of the brake disc assembly 1 is located inside the caliper assembly 2. The brake disc assembly 1 is mounted on the wheel hub of an external motorcycle, and the caliper assembly 2 is mounted on the frame of an external motorcycle. The brake disc assembly 1 includes a disc body 101, and an annular notch 102 is formed inside the disc body 101. A water spray ring 103 is rotatably mounted inside the notch 102. A connecting rigid tube 104 is fixedly mounted on one end of the water spray ring 103, and one end of the connecting rigid tube 104 is threadedly connected to the caliper assembly 2. The caliper assembly 2 consists of a fixed caliper mechanism 21 and a movable caliper mechanism 22, which slides and engages. On the fixed caliper mechanism 21, grooves 23 are provided on the opposite side of the movable caliper mechanism 22. The first brake pad 24 is fixedly installed inside the groove 23 on the movable caliper mechanism 22, and the second brake pad 25 is slidably engaged inside the groove 23 on the fixed caliper mechanism 21. A cleaning component 3 for cleaning the brake disc assembly 1 is obliquely inserted into the upper end of the fixed caliper mechanism 21. When in use, the assembly is performed first, and water is selectively supplied to the water spray ring 103 depending on whether the external motorcycle is equipped with a water supply device. During assembly, the disc body 101 in the brake disc assembly 1 is first fixedly connected to the motorcycle wheel hub shaft, and the caliper assembly 2 is installed on the frame. This arrangement positions one side of the disc 101 between the fixed caliper mechanism 21 and the movable caliper mechanism 22. After installing the brake disc assembly 1 and the caliper assembly 2, the cleaning component 3 is inserted into the fixed caliper mechanism 21 in the caliper assembly 2. Then, the water spray ring 103 is rotated, causing one end of the connecting rigid tube 104 to be threadedly connected to the fixed caliper mechanism 21 in the caliper assembly 2. This fixes the water spray ring 103 and the connecting rigid tube 104. During riding, the disc 101 rotates with the motorcycle tires, driving the cleaning component 3 to clean both sides of the disc 101, preventing dust from adhering and improving the cleanliness of the disc 101 surface. During braking, the first brake pad 24 moves towards the second brake pad 25 along with the movable caliper mechanism 22. The second brake pad 25 moves towards the first brake pad 24 inside the groove 23, so that the first brake pad 24 and the second brake pad 25 clamp the disc 101. By using friction, the disc 101 is braked. At the same time, when the motorcycle is equipped with a water supply device, the external water supply device supplies water to the connecting hard pipe 104 and sprays it out through the water spray ring 103 to cool the disc 101 with water. This prevents the temperature of the disc 101 from rising sharply during continuous and frequent braking, which could reduce the braking effect or cause brake failure, and improves the stability during braking.

[0029] As a technical optimization solution of the present invention, specifically as follows: Figures 3-5As shown, the disc body 101 has a circular structure, and the inner ring of the disc body 101 has a first mounting lug 105 fixedly installed in a circular array. The disc body 101 forms an I-shaped structure through a notch 102. A bearing 106 is fixedly installed inside the notch 102, and the outer ring of the bearing 106 is fixedly connected to the water spray ring 103. Water spray nozzles 107 are obliquely opened on both sides of the outer ring of the water spray ring 103. A connecting nut 108 is rotatably installed at one end of the connecting rigid pipe 104. The first mounting lug 105 facilitates the use of external bolts to fix the disc body 101 to the motorcycle wheel hub shaft for a fixed connection. The notch 102 improves the airflow effect inside the disc body 101, facilitating air cooling. When the disc 101 rotates, the water spray ring 103 remains stable, and the water sprayed out through the inclined spray nozzle 107 sprays cooling water towards both sides of the inside of the disc 101. This facilitates the even distribution of the sprayed water onto the disc 101 by utilizing the surface tension of the water and the centrifugal force of the disc 101 during rotation. The connecting nut 108 facilitates the threaded connection between the rigid pipe 104 and the fixing caliper mechanism 21, allowing for easy connection to the water supply device on the motorcycle. The disc 101 has a circumferential array of heat dissipation holes 109. Fins 1010 are fixedly installed in a circumferential array on both sides of the notch 102. Each fin 1010 has an arc-shaped structure, and the fins 1010 on both sides are arranged in a symmetrical pattern. The fins 1010 are distributed in a manner such that one end of the fin near the outer side of the disk 101 is bent to form an arc-shaped hook 1011. A water passage hole 1012 is provided at the center of the arc-shaped hook 1011 on the disk 101. The side of the fin away from the disk 101 is bent to form a baffle 1013. Through the heat dissipation hole 109, the airflow effect is improved when the disk 101 rotates, and the contact area between the disk 101 and the external air is increased, thereby improving heat dissipation performance and reducing the overall weight of the disk 101. By installing the fins 1010 inside the notch 102, when the disk 101 rotates, the built-in fins 1010 form a turbulent shear layer, which increases the airflow velocity around the disk 101 and enhances forced convection. The cooling effect facilitates air cooling, improves heat dissipation performance when the motorcycle is not equipped with a water supply device, reduces heat accumulation, and when the motorcycle is equipped with a water supply device, the cooling water is sprayed out through the spray nozzle 107 on the spray ring 103. Using centrifugal force, the cooling water is thrown out to the outside of the disc 101. Guided by the fins 1010, the cooling water is concentrated at the arc hook 1011 position, and the baffle 1013 improves the water concentration capacity at the arc hook 1011 position. When the water concentration is sufficient, the cooling water flows to the outer sides of the disc 101 through the water passage 1012, which facilitates rapid cooling, reduces the surface temperature of the disc 101, reduces heat exhaustion, and improves thermal stability during continuous braking.

[0030] As a technical optimization solution of the present invention, specifically as follows: Figures 6-8As shown, the fixed caliper mechanism 21 includes a fixed caliper 2101. A second mounting ear 2102 is fixedly installed on one side of the fixed caliper 2101, and a first hydraulic cylinder 2103 is fixedly installed on the outer side of the fixed caliper 2101. The telescopic end of the first hydraulic cylinder 2103 extends into the groove 23 of the fixed caliper mechanism 21 and is fixedly connected to the second brake pad 25. A guide hole 2104 is provided on the fixed caliper 2101 on one side of the first hydraulic cylinder 2103. One end of the movable caliper mechanism 22 is inserted into the guide hole 2104. A second hydraulic cylinder 2105 is fixedly installed on one side of the fixed caliper 2101 between the two guide holes 2104, and the telescopic end of the second hydraulic cylinder 2105 is fixedly connected to the movable caliper mechanism 22. The first hydraulic cylinder 2103... The hydraulic circuit is connected to the second cylinder 2105. During installation, the second mounting ear 2102 facilitates the fixing of the caliper assembly 2 to the frame. During braking, hydraulic oil from the external upper pump is pumped into the first cylinder 2103 and the second cylinder 2105. The extension end of the first cylinder 2103 extends, pushing the second brake pad 25. The extension end of the second cylinder 2105 extends, pulling the movable caliper mechanism 22. The movable caliper mechanism 22 moves along the guide hole 2104 toward the first cylinder 2103, causing the first brake pad 24 to move toward the second brake pad 25. This shortens the distance between the first brake pad 24 and the second brake pad 25, making the first brake pad 24 and the second brake pad 25 more evenly aligned. 25 clamps the disc 101 to achieve a braking effect. A hydraulic connector 2106 is fixedly installed on one side of the clamping clamp 2101, and a connecting hydraulic pipe 2107 is fixedly installed on one side of the second cylinder 2105. One end of the connecting hydraulic pipe 2107 is connected to the hydraulic connector 2106, and one end of the hydraulic connector 2106 is connected to the external brake booster. A water connector 2108 is fixedly installed on the upper end of the clamping clamp 2101, and one end of the connecting rigid pipe 104 is threaded onto the water connector 2108. Through the connecting hydraulic pipe 2107 and the hydraulic connector 2106, the first cylinder 2103 and the second cylinder 2105 are easily connected to the external booster, allowing the booster to pump energy into the first cylinder 2103 and the second cylinder 2105. Hydraulic oil causes the first cylinder 2103 and the second cylinder 2105 to extend and retract. A rigid pipe 104 is threadedly connected to the water connector 2108 via a connecting nut 108. When the motorcycle is equipped with a water supply device, the external water supply device is connected to the rigid pipe 104 through the water connector 2108, facilitating water supply to the inside of the spray ring 103. When the motorcycle is not equipped with a water supply device, the rigid pipe 104 is threaded onto the water connector 2108, facilitating the fixation of the rigid pipe 104 and the spray ring 103, preventing the rigid pipe 104 from rotating with the disc body 101. After installation, the rigid pipe 104 limits one end of the cleaning component 3.To prevent the cleaning component 3 from detaching from the fixing clamp mechanism 21, the upper end of the fixing clamp 2101 is inclinedly fixed with T-shaped sliding grooves 2109 on both sides. The two ends of the cleaning component 3 are slidably engaged inside the sliding grooves 2109. The sliding grooves 2109 facilitate quick assembly and disassembly of the cleaning component 3, allowing for easy replacement of the cleaning component 3 when it shows wear after prolonged use, thus simplifying maintenance.

[0031] As a technical optimization solution of the present invention, specifically as follows: Figures 6-8 As shown, the movable caliper mechanism 22 includes a movable plate 2201. A groove 23 on the movable caliper mechanism 22 is formed on the movable plate 2201, and the first brake pad 24 is fixedly connected to the movable plate 2201. Guide rods 2202 are fixedly installed at both ends of one side of the movable plate 2201. The guide rods 2202 are inserted into the guide holes 2104 and extend to one side of the fixed caliper 2101. A connecting plate 2203 is fixedly installed between the two guide rods 2202. The connecting plate 2203 is fixedly connected to the extension end of the second hydraulic cylinder 2105. Through the guide rods 2202 and the connecting plate 2203, when the second hydraulic cylinder 2105 extends or retracts, it drives the movable plate 2201 to move, thereby causing the first brake pad 24 to move, achieving the effect of pressing or moving away from the disc 101, which facilitates braking.

[0032] As a technical optimization solution of the present invention, specifically as follows: Figure 9 and Figure 10As shown, the cleaning component 3 includes a gantry frame 301. Slider blocks 302, which match the slide groove 2109, are provided on both sides of the gantry frame 301. The gantry frame 301 is slidably engaged with the slide groove 2109 via the sliders 302. Handles 303 are fixedly installed on both sides of the upper end of the gantry frame 301. Brushes 304 are rotatably mounted on both sides of the interior of the gantry frame 301. One side of the brush 304 contacts the brake disc assembly 1. A first bevel gear 305 is fixedly installed on the shaft at one end of the brush 304. The handles 303 and sliders 302 facilitate the cleaning of the gantry frame 301. The brush 304 is installed inside the slide groove 2109 and is driven by the rotating disc 101. The disc 101 and brush 304 move at a differential speed, facilitating the cleaning of dust or dirt adhering to the surface of the disc 101, improving surface cleanliness, thus enhancing stability during braking and effectively protecting the disc 101 surface from scratches, extending its service life. Second bevel gears 306 are rotatably mounted on both sides of the inner side of the gantry frame 301. The first bevel gear 305 meshes with the second bevel gear 306, and the gantry... A rubber roller 307 is rotatably mounted in the middle of the inner part of the frame 301. The rubber roller 307 contacts the outer side of the brake disc assembly 1 and is linked with the second bevel gear 306. When the disc body 101 rotates, the rubber roller 307 rotates, thereby driving the second bevel gear 306. The second bevel gear 306 meshes with the first bevel gear 305 at one end of the brush 304, thereby causing the brush 304 to rotate and achieving the effect of cleaning the surface of the disc body 101. Drive teeth are fixedly mounted at both ends of the rubber roller 307. The second bevel gear 306 has a differential gear 309 fixedly installed at one end. The differential gear 309 meshes with the drive gear 308. When the rubber roller 307 rotates, the rubber roller 307 drives the drive gear 308. Through the differential gear 309, the rotation speed of the second bevel gear 306 and the rubber roller 307 changes. The first bevel gear 305 meshes with the second bevel gear 306, thereby creating a speed difference between the rotation speed of the brush 304 and the rotation speed of the disc 101, which facilitates the brush 304 to clean the surface of the disc 101.
