Description

Technical Field

[0001] The utility model belongs to the field of bicycles and relates to bicycle brake technology, in particular to a bicycle brake with a wear-resistant SIC composite coating that increases friction. Background Art

[0002] Bicycle brakes are an important safety device for bicycles. Their main function is to help riders slow down or stop when necessary to ensure driving safety. The working principle of the brake is to prevent the rotation of the wheels through friction, thereby stopping or slowing down the bicycle.

[0003] Bicycle brakes help control the speed of the vehicle, allowing the rider to adjust the speed when necessary to adapt to different road conditions and riding needs. For example, when going downhill or riding at high speed, the brakes can help the rider slow down and maintain safe riding. In short, bicycle brakes are an important device to ensure riding safety. Therefore, riders should regularly check and maintain the normal working condition of the brakes to ensure that they can play an effective braking role when needed.

[0004] When a rider is riding a bicycle, water may directly stain or splash onto the tire hub due to the riding route or weather. The water may be muddy water directly attached to the hub. If it is dew or clear water, some dust or grass seeds may adhere to the hub. When the bicycle brake is in use, the muddy water, dust, etc. are between the hub and the brake, affecting the friction between the bicycle brake and the hub.

[0005] Therefore, we propose a bicycle brake with a wear-resistant SIC composite coating that increases friction to solve the above problems. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 - Figure 4 As shown, a bicycle brake with a wear-resistant SIC composite coating that increases friction comprises a base 1, both sides of the front and back sides of the base 1 are rotatably connected with clamp arms 2, both sides of the two clamp arms 2 are fixedly connected with extension plates 3, both ends of the two extension plates 3 are fixedly installed with cleaning components 4, the bottoms of the opposite sides of the two clamp arms 2 are fixedly connected with support rods 5, the opposite ends of the two support rods 5 are fixedly connected with fixing plates 6, the middles of the opposite sides of the two fixing plates 6 are fixedly connected with T-shaped plates 7, a brake component 8 is arranged on one side of the fixing plate 6, and one end of the T-shaped plate 7 extends to the interior of the brake component 8.

[0023] It should be noted that the base 1 is installed together with the body of the bicycle, and the two clamping arms 2 are connected to the base 1. Under the control of the brake lever and the brake cable, the two brake assemblies 8 can be driven to shrink toward the middle together and contact the bicycle wheel hub to realize bicycle braking. The extension plate 3 is welded to the two clamping arms 2 and extends to both sides to provide a support and fixed position for the cleaning assembly 4. A hole is provided on the extension plate 3, and one end of the cleaning assembly 4 passes through the hole on the extension plate 3. The ends of the four cleaning assemblies 4 contact the bicycle wheel hub, so that dust, water stains, etc. on the bicycle wheel hub can be cleaned. The support rod 5 is fixed together with the clamping arms 2 to connect the fixing plate 6. The T-plate 7 is welded to one side of the fixing plate 6, and the brake assembly 8 is stuck on the surface of the T-plate 7. If the brake assembly 8 is severely worn after long-term use, it is convenient to replace the brake assembly 8.

[0024] In the present application, the cleaning assembly 4 includes a sliding rod 41, one end of the surface of the sliding rod 41 is sleeved with a spring 42, one end of the spring 42 is fixedly installed on one side of the extension plate 3, one end of the sliding rod 41 is fixedly connected to a connecting plate 43, and first card grooves 44 are opened on both sides of the surface of the connecting plate 43.

[0025] In the present application, an arc-shaped scraper block 45 is provided on one side of the connecting plate 43, and a clamping block 46 is fixedly connected to one side of the arc-shaped scraper block 45. One end of the clamping block 46 extends to the inside of the first clamping groove 44, and the two arc-shaped scrapers 45 are in opposite directions.

[0026] It should be noted that the slide bar 41 is adapted to the size of the hole on the extension plate 3, and the slide bar 41 passes through the hole to ensure that its position does not deviate up, down, left, or right. One end of the spring 42 is clamped together with the extension plate 3, and the other end is clamped together with the connecting plate 43. The spring 42 is a compression spring with good elasticity. The arc scraper block 45 is made of rubber and is in contact with the bicycle wheel hub. The arc scraper block 45 is fixed together with the clamping block 46, and is clamped in the first clamping groove 44 on one side of the connecting plate 43 by the clamping block 46. After a long time, if the arc scraper block 45 is aged or worn, it can be easily replaced without the need to disassemble the entire bicycle brake.

[0027] In the present application, threaded holes 9 are provided on both sides of the top of the T-shaped plate 7 , and long rod bolts 10 are provided on both sides of the top of the brake assembly 8 , and the bottom threads of the two long rod bolts 10 extend into the interior of the threaded holes 9 .

[0028] It should be noted that the two long-rod bolts 10 are matched in size with the two threaded holes 9 , and the brake assembly 8 and the T-plate 7 can be stably restrained and fixed together by rotating the two long-rod bolts 10 into the threaded holes 9 .

[0029] In the present application, the brake assembly 8 includes a fixed seat 81, a brake block 82 is fixedly mounted on one side of the fixed seat 81, a coating 83 is provided on the surface of the brake block 82, a second slot 84 is opened on one side of the fixed seat 81, and connecting holes 85 are opened on both sides of the top of the fixed seat 81, and the bottoms of the inner surfaces of the two connecting holes 85 are connected to the interior of the second slot 84.

[0030] It should be noted that coating 83 is a SIC composite coating, which is a new type of ceramic material. It has the characteristics of strong adhesion between the coating and the substrate, coating density and high thermal radiation. The SIC composite coating is prepared on the surface of the part by physical or chemical vapor deposition, spraying and other methods, mainly utilizing its wear resistance and ablation resistance. Coating 83 can extend the service life of the brake block 82. The T-plate 7 is stuck in the second slot 84, and the two connecting holes 85 are connected to the second slot 84 and are located corresponding to the position of the threaded hole 9. The long rod bolt 10 enters the threaded hole 9 through the connecting hole 85.

[0031] When the utility model is implemented:

[0032] According to the utility model, when the bicycle is normally ridden, dust or water droplets raised by the contact between the bicycle tire and the ground adhere to the bicycle wheel hub. During the normal rotation of the bicycle tire, the cleaning components 4 located on both sides of the wheel hub can always be in contact with the surface of the wheel hub, and the water stains or dust adhered to the surface of the wheel hub can be brushed off by the arc-shaped scraper block 45, but the normal rotation of the bicycle tire will not be affected, and the brushed off water stains or dust can drip downward along the arc-shaped scraper block 45, ensuring that the relatively clean or dry wheel hub is moved between the two brake components 8, and the brake components 8 can be stably clamped on both sides of the wheel hub;

[0033] When the bicycle brake is needed, the brake blocks 82 on both sides move together toward the middle bicycle wheel hub, and the bicycle wheel hub here is cleaned by the cleaning components 4 on both sides, and the brake blocks 82 directly contact the bicycle wheel hub. At the same time, the arc-shaped scraping blocks 45 in the cleaning components 4 on both sides also move with the movement of the clamping arm 2, and contact the bicycle wheel hub together with the brake blocks 82, so that the bicycle tire stops rotating. At the same time, when one end of the cleaning component 4 is pressed by the bicycle wheel hub, the spring 42 is pressed, and the slide bar 41 extends to the other side of the extension plate 3 to ensure that it can be stably located on the side of the wheel hub;

[0034] When the brake block 82 contacts the surface of the bicycle wheel hub, the coating 83 on the surface of the brake block 82 contacts the wheel hub, and when the friction between the brake block 82 and the wheel hub generates heat, the SIC composite coating 83 is ablation-resistant and wear-resistant, which can extend the service life of the brake block 82 and increase the friction between the brake block 82 and the bicycle wheel hub. When the bicycle tire is rotated backward, the two groups of cleaning components 4 on the other side clean the surface of the wheel hub, ensuring that the wheel hub between the front and rear groups of cleaning components 4 is always kept clean, avoiding various impurities, water stains, etc. on the wheel hub that affect the friction between the brake component 8 and the wheel hub;

[0035] When the arc scraper block 45 and the brake block 82 are used for a long time and still wear out or the arc scraper block 45 is aged due to wind and sun, the rider only needs to lift the arc scraper block 45 upward along the first slot 44 to replace the arc scraper block 45, and then clamp the new arc scraper block 45 in the first slot 44, and after the bottom ends of the two long rod bolts 10 are rotated out of the threaded holes 9, the brake assembly 8 is directly removed from the T-plate 7 along the second slot 84, and then replaced with a new brake assembly 8.

[0036] By welding the extension plates 3 on both sides of the two clamping arms 2, four cleaning components 4 are installed on the extension plates 3. When the bicycle wheel hub rotates, the ends of the cleaning components 4 can contact the surface of the wheel hub to wipe off the dust and water stains on the surface of the wheel hub. At the same time, the cleaning components 4 will not generate excessive friction with the bicycle wheel hub. When the bicycle brakes are used, the brake components 8 contact the bicycle wheel hub, and the cleaning components 4 can also move to the middle with the bicycle brakes, so that the contact area between the cleaning components 4 and the bicycle wheel hub is increased, thereby improving the braking effect in cooperation with the bicycle brakes.

[0037] By arranging a support rod 5, a fixing plate 6, a T-plate 7 and a brake assembly 8 between the two clamp arms 2, the brake block 82 in the brake assembly 8 contacts the surface of the bicycle wheel hub, and the long rod bolt 10 is rotated into the threaded hole 9 on the T-plate 7. After the friction of the brake block 82 in the brake assembly 8 decreases after long-term use or it is severely worn, the long rod bolt 10 can be directly rotated out, and the brake assembly 8 can be disassembled from the T-plate 7 from the side and replaced. The replacement is convenient and fast, and it is convenient for personnel to use.

[0038] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
