Description

Technical Field

[0001] This invention relates to the field of motorcycle disc brake assembly technology, specifically a high-braking-torque safety motorcycle disc brake assembly. Background Technology

[0002] Motorcycle disc brake assemblies are a safety device. During motorcycle operation, the wheels drive the brake disc to rotate at high speed. When the rider needs to stop the vehicle, the internal hydraulic mechanism is activated, pressurizing the brake system and causing the brake pads to contact the rotating brake disc, generating friction and achieving a deceleration effect. However, existing disc brake assemblies still have some problems: For example, a high-strength anti-corrosion disc brake assembly with publication number CN216478590U includes a disc brake disc assembly. The disc brake disc assembly includes a first ring, a second ring, and a third ring. The first ring and the second ring are connected by a connecting rod. The third ring is sleeved on the second ring. A brake caliper device for braking is provided above the third ring. The aforementioned device has a relatively fixed brake pad installation method, making it difficult for users to quickly remove the brake pads during device maintenance, thus increasing the user's labor intensity. Also refer to the motorcycle single-cylinder disc brake with publication number CN217381376U, which includes a brake disc, fixed arms fixedly installed on both sides of the brake disc, a hydraulic cylinder fixedly installed in the middle of the fixed arms, and mounting holes opened at one end of each fixed arm. A stabilizing mechanism is fixedly installed inside the mounting hole. The stabilizing mechanism includes a stabilizing frame fixedly connected inside the mounting hole. Through the stabilizing mechanism, when the motorcycle is in motion, the brake disc follows the vibration and impact, and the stabilizing frame installed on the fixed arm is activated. The aforementioned device uses a relatively simple braking method, relying solely on two brake pads to clamp the brake disc for frictional deceleration. This results in a single source of braking torque and a weak braking effect.

[0003] To address the aforementioned issues, there is an urgent need for innovative design based on the existing disc brake assembly. Summary of the Invention

[0004] The purpose of this invention is to provide a high-braking-torque safety motorcycle disc brake assembly to solve the problems mentioned in the background art. The existing disc brake assemblies have a relatively fixed installation method for the brake pad structure. During the device maintenance process, it is difficult for the user to quickly remove the brake pads. Moreover, the braking method is relatively simple, which only relies on the two brake pads to clamp the brake disc for frictional deceleration. The braking torque of the device comes from a single source, and the braking effect of the device is not strong.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high braking torque safety motorcycle disc brake assembly, comprising: The outer shell has foot plates on both sides that are fixed to the frame by bolts. The outer shell is fitted onto the outer edge of the brake disc, and the mounting hole in the middle of the brake disc is fixed to the drive shaft of the wheel by bolts. The inner wall of the outer shell has symmetrically distributed loading boxes that are slidably installed on both sides of the brake disc. Also includes: The brake pads are slidably embedded in the corresponding loading box to form a detachable structure.

[0007] Preferably, symmetrically distributed guide rods are fixedly connected between the tops of the first clamp plate and the second clamp plate, and the guide rods are horizontally arranged. The two guide rods penetrate the inner wall of the outer shell to form a sliding limiting structure, so that the guide rods can move inside the outer shell.

[0008] Preferably, an ear plate is slidably passed through the side of the guide rod near the first clamp plate, and the ear plate is fixedly installed on the top of the corresponding loading box. A protruding ring is provided on the side wall of the guide rod, and a return spring is fixedly connected between the annular surface of the protruding ring and the side wall of the ear plate. The return spring is sleeved on the rod body of the guide rod, so that the ear plate and the guide rod can compress the return spring.

[0009] Preferably, symmetrically distributed main pressure cylinders are fixedly installed on the side wall of the first clamp plate, and the main pressure cylinders are horizontally slidably installed through the side wall of the outer shell. The piston of the main push rod is attached to the inner wall of the main pressure cylinder, and the rod body of the main push rod is slidably installed through the first clamp plate. At the same time, the end face of the main push rod is vertically fixedly connected to the loading box attached to the first clamp plate, so that the main push rod can move on the first clamp plate.

[0010] Preferably, a second spring is sleeved on the outer side of the pressure rod, and the second spring is fixedly connected between the bottom surface of the pressure cylinder and the top surface of the pressure cylinder. A plug of the force-bearing rod is coaxially fitted inside the pressure cylinder, and a first spring is fixedly connected between the upper end face of the plug and the top of the inner wall of the pressure cylinder. A resistance block is coaxially connected to the lower end face of the force-bearing rod, and the two sides of the resistance block are fitted against the inner wall of the outer shell. The bottom of the resistance block is located above the outer edge of the brake disc, and the outer edge of the brake disc has a wavy structure. The axis of the brake disc intersects perpendicularly with the axis of the force-bearing rod, so that the force-bearing rod can move inside the pressure cylinder.

[0011] Preferably, the upper port of the auxiliary infusion pipe is fixedly installed through the upper part of the side wall of the pressurizing cylinder, and the lower port of the auxiliary infusion pipe is fixedly connected to the end of the auxiliary pressurizing cylinder. The auxiliary infusion pipe passes through the opening at the bottom of the protective cover, so that the oil in the pressurizing cylinder can flow into the auxiliary pressurizing cylinder through the auxiliary infusion pipe.

[0012] Preferably, the auxiliary pressure cylinder is disposed between the two main pressure cylinders, and the auxiliary pressure cylinder slides through the side wall of the outer shell. The auxiliary pressure cylinder is fixedly connected to the side wall of the first clamping plate. The inner wall of the auxiliary pressure cylinder is fitted with the plug of the auxiliary push rod, and the rod body of the auxiliary push rod slides through the first clamping plate.

The bottom of both the brake pad and the loading box is tightly fitted with a sealing cover, and symmetrically distributed positioning bolts are slidably installed on both sides of the sealing cover. The ends of the two positioning bolts are threaded to the bottom of the loading box. When it is necessary to remove the brake pad, use a maintenance tool to rotate the positioning bolts so that the two positioning bolts are disengaged from the bottom of the loading box, and then the sealing cover can be removed from the loading box, and the brake pad can be pushed out from the bottom of the loading box. 2. A plug body with a force-bearing rod is coaxially attached to the inner side of the pressure cylinder. A first spring is fixedly connected between the upper end face of the plug body and the top of the inner wall of the pressure cylinder. A resistance block is coaxially attached to the lower end face of the force-bearing rod. The bottom of the resistance block is located above the outer edge of the brake disc. The outer edge of the brake disc has a wavy structure. When the resistance block moves downward, the rotating brake disc can contact the resistance block, so that the resistance block and the brake pad can provide a dual braking torque to the brake disc.

Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-11 This invention provides a technical solution: a high-braking-torque safety motorcycle disc brake assembly, comprising: The outer shell 1 has foot plates on both sides that are fixed to the frame by bolts. The outer shell 1 is fitted onto the outer edge of the brake disc 2, and the mounting hole in the middle of the brake disc 2 is fixed to the drive shaft of the wheel by bolts. The inner wall of the outer shell 1 is slidably mounted with symmetrically distributed loading boxes 3, which are symmetrically distributed on both sides of the brake disc 2. Brake pads 4 are slidably embedded in the corresponding loading box 3 to form a detachable structure. Brake pads 4 are symmetrically distributed on both sides of brake disc 2, and there is a gap between brake pads 4 and brake disc 2. The bottom of brake pads 4 and loading box 3 are tightly fitted with sealing covers 5, and symmetrically distributed positioning bolts 6 are slidably installed on both sides of sealing covers 5, and the ends of the two positioning bolts 6 are threaded to the bottom of loading box 3. A protective cover 18 is vertically fixedly installed at the top center of the outer shell 1. A pressure cylinder 16 is coaxially mounted on the top of the protective cover 18. A plug at the upper end of a pressure rod 17 is attached to the inner wall of the pressure cylinder 16. The rectangular rod of the pressure rod 17 passes through the bottom of the pressure cylinder 16 to form a sliding limiting structure. A pressure cylinder 19 is coaxially mounted on the bottom surface of the pressure rod 17. The pressure cylinder 19 is slidably inserted into the mounting groove opened at the top of the outer shell 1. One end of the main infusion pipe 15 is fixedly connected to the upper side wall of the pressure cylinder 16. The other end of the main infusion pipe 15 is fixedly connected to the inlet of the guide member 14. The two outlets of the guide member 14 are respectively fixedly connected to the through holes of the corresponding main pressure cylinder 13 to form an infusion structure.

[0018] Symmetrically distributed main pressure cylinders 13 are fixedly installed on the side wall of the first clamping plate 7, and the main pressure cylinders 13 slide horizontally through the side wall of the outer shell 1. A piston of a main push rod 12 is attached to the inner wall of the main pressure cylinder 13, and the rod of the main push rod 12 slides through the first clamping plate 7. The end face of the main push rod 12 is vertically fixedly connected to a loading box 3 attached to the first clamping plate 7, so that the main pressure cylinder 13 can drive the first clamping plate 7 to move, and the main push rod 12 can drive the corresponding loading box 3 to move. The inner wall of the outer shell 1 is attached to the first clamping plate 7 and the second clamping plate 9, and two loading boxes 3 are arranged between the first clamping plate 7 and the second clamping plate 9. One loading box 3 is attached to the side wall of the first clamping plate 7, and another loading box 3 is fixedly installed on the outer wall of the second clamping plate 9. The main push rod 12 can push the corresponding loading box 3 closer to the brake disc 2 for braking operation. Since the top of the first clamp plate 7 and the second clamp plate 9 are fixedly connected with symmetrically distributed guide rods 8, and the guide rods 8 are set horizontally, and the two guide rods 8 pass through the inner wall of the outer shell 1 to form a sliding limit structure, the first clamp plate 7 can drive the second clamp plate 9 to move synchronously through the guide rods 8. The side of the guide rod 8 near the first clamp plate 7 has a sliding ear plate 10, and the ear plate 10 is fixedly installed on the top of the corresponding loading box 3. A protruding ring is provided on the side wall of the guide rod 8, and a return spring 11 is fixedly connected between the ring surface of the protruding ring and the side wall of the ear plate 10. The return spring 11 is sleeved on the rod body of the guide rod 8, and the guide rods 8 and the ear plate 10 moving in opposite directions compress the return spring 11 together.

[0019] A second spring 26 is sleeved on the outer side of the pressure rod 17, and the second spring 26 is fixedly connected between the bottom surface of the pressure cylinder 16 and the top of the pressure cylinder 19. A plug of the force-bearing rod 21 is coaxially fitted inside the pressure cylinder 19, and a first spring 20 is fixedly connected between the upper end face of the plug and the top of the inner wall of the pressure cylinder 19. A resistance block 22 is coaxially connected to the lower end face of the force-bearing rod 21, and the two sides of the resistance block 22 are fitted against the inner wall of the outer casing 1. The bottom of the resistance block 22 is positioned above the outer edge of the brake disc 2, and the outer edge of the brake disc 2 has a wavy structure. The axis of the brake disc 2 intersects perpendicularly with the axis of the force-bearing rod 21. When the pressure rod 17 moves the pressure cylinder 19 downwards, the force-bearing rod 21 inside the pressure cylinder 19 will move the resistance block 22 synchronously, allowing the resistance block 22 to contact the outer edge of the brake disc 2. The brake disc 2 will then push the resistance block 22 upwards, causing the resistance... Block 22 can push the force rod 21 to move, and the force rod 21 will squeeze the oil in the pressure cylinder 19. The upper port of the auxiliary infusion pipe 23 is fixedly installed through the upper part of the side wall of the pressure cylinder 19, and the lower port of the auxiliary infusion pipe 23 is fixedly connected to the end of the auxiliary pressure cylinder 24. The auxiliary infusion pipe 23 passes through the opening at the bottom of the protective cover 18, and the oil in the pressure cylinder 19 flows into the auxiliary pressure cylinder 24 through the auxiliary infusion pipe 23. Since the auxiliary pressure cylinder 24 is set between the two main pressure cylinders 13 The auxiliary pressure cylinder 24 is slidably installed through the side wall of the outer shell 1 and is fixedly connected to the side wall of the first clamping plate 7. The plug of the auxiliary push rod 25 is attached to the inner wall of the auxiliary pressure cylinder 24, and the rod body of the auxiliary push rod 25 is slidably installed through the first clamping plate 7. The end face of the auxiliary push rod 25 is attached to the corresponding loading box 3, so that the oil in the auxiliary pressure cylinder 24 can push the auxiliary push rod 25 to move, and the auxiliary push rod 25 will apply pressure to the loading box 3.

[0020] Working principle: When using this high-braking-torque safety motorcycle disc brake assembly, first refer to... Figure 1-11The brake disc 2 is fixed to the wheel, while the outer casing 1 is fixed to the frame. The upper end of the pressure cylinder 16 is connected to the hydraulic inlet pipe of the vehicle body. When the vehicle moves, the wheel drives the brake disc 2 to rotate. When braking is required, the user presses the hydraulic structure of the vehicle body, allowing the hydraulic fluid to flow into the pressure cylinder 16. The high-pressure hydraulic fluid in the pressure cylinder 16 flows into the guide 14 through the main inlet pipe 15, and the hydraulic fluid in the guide 14 flows into the two main pressure cylinders 13. The high-pressure hydraulic fluid pushes the main push rod 12 to... As the main pressure cylinder 13 moves, the end of the main push rod 12 pushes the corresponding loading box 3 to move, causing the loading box 3 to move the brake pad 4 away from the first caliper plate 7. The loading box 3 will then move the corresponding ear plate 10. When the brake pad 4 contacts the rotating brake disc 2, the loading box 3 and the main push rod 12 will be unable to move. At this time, the main pressure cylinder 13 will move the first caliper plate 7 away from the brake disc 2. The first caliper plate 7 will move the second caliper plate 9 synchronously through the guide rod 8. At this time, the guide rod 8 and the ear plate 10 will move in opposite directions. This will cause the convex ring of the guide rod 8 and the ear plate 10 to compress the return spring 11. The second caliper plate 9 will move the loading box 3 fixedly connected to the side wall closer to the brake disc 2. As can be seen from the above steps, the two loading boxes 3 will move the corresponding brake pad 4 to press against the brake disc 2 for braking, generating the first heavy braking torque. See Figure 1-11 During the above process, the high-pressure oil in the pressure cylinder 16 will synchronously push the pressure rod 17 downward, causing the pressure rod 17 to push the pressure cylinder 19 to move synchronously. The pressure cylinder 19 will stretch the second spring 26. The pressure cylinder 19 and the auxiliary infusion pipe 23 contain oil. The force rod 21 in the pressure cylinder 19 will drive the resistance block 22 to move synchronously downward, so that the resistance block 22 can contact the wavy outer edge of the brake disc 2, allowing the brake disc 2 to push the resistance block 22 to move. During this process, the resistance block 22 will generate a second braking torque. At the same time, when the brake disc 2 pushes the resistance block 22 upward, the resistance block 22 will drive the force rod 21 to move synchronously, causing the force rod 21 to push the resistance block 22 upward. The plug in the part can compress the first spring 20 inside the pressure cylinder 19. At the same time, the force rod 21 will pressurize the oil in the pressure cylinder 19 into the auxiliary infusion pipe 23, and the oil in the auxiliary infusion pipe 23 will flow into the auxiliary pressure cylinder 24. The high-pressure oil will push the auxiliary push rod 25 to move, so that the auxiliary push rod 25 can move on the first clamp plate 7. The end of the auxiliary push rod 25 will apply auxiliary pressure to the loading box 3, thereby further increasing the braking torque of the brake pad 4. When the brake pad 4 needs to be replaced, the positioning bolts 6 are rotated with maintenance tools to disengage the two positioning bolts 6 from the bottom of the loading box 3, so that the sealing cover 5 can be removed from the loading box 3, and then the brake pad 4 can be pushed out from the bottom of the loading box 3.
