Description

Technical Field

[0001] This utility model relates to the field of motor equipment technology, specifically to a high-power disc brake motor. Background Technology

[0002] Traditional braking systems are often installed separately from the motor. This separate design may lead to problems such as insufficient braking response and unstable braking effect when dealing with high-power motor output. For example, when an electric motorcycle is traveling at high speed, the high-power motor drives the vehicle to a high speed. When emergency braking is required, the ordinary braking system may not be able to quickly and effectively convert the huge kinetic energy of the vehicle into heat energy and dissipate it, resulting in an excessively long braking distance and posing a safety hazard.

[0003] Moreover, as vehicle power continues to increase, the heat generated by the motor during operation, especially during braking, also increases dramatically. If heat cannot be dissipated in a timely and effective manner, it will not only affect the performance and lifespan of the motor, but may also lead to thermal fade in the braking system, further reducing the braking effect.

[0004] In view of this, we will study and improve the existing structure and its shortcomings to provide a high-power disc brake motor, in order to achieve a more practical purpose. Utility Model Content

[0007] The heat dissipation component is installed on the outside of the fixed post to dissipate the large amount of heat generated when the motor disc brakes. A disc is fixedly connected to the outside of the fixed post, and a groove is opened in the center of the disc.

[0008] Preferably, a brake pad is fixedly connected to the outside of the fixed column, and the brake pad has many irregular heat dissipation holes on its outside. The brake pad is in the shape of an iron ring, and a brake disc is installed on the top of the brake pad.

[0009] Preferably, the top of the brake pad is slidably connected to two sets of brake pads, the brake pads are made of rubber, the outside of the brake pads is fixedly connected to a movable plug, the movable plug is slidably connected to a mounting bracket, and the movable plug is covered with a shell.

[0012] Preferably, the bracket connected to the outside of the connecting ring is fixedly connected to a frame, and the inside of the frame is rotatably connected to a fan blade, and the inside of the fan blade is fixedly connected to the outside of the bracket.

[0013] Compared with the prior art, this utility model provides a high-power disc brake motor, which has the following beneficial effects:

[0014] By creating holes inside the mounting bracket and slidingly connecting the telescopic rod, the telescopic rod can limit and assist the movement of the brake pads. During braking, the telescopic rod can prevent the brake pads from excessive displacement or shaking, further improving the stability and reliability of the braking structure. At the same time, the fluid infusion pipe fixedly connected to the outside of the mounting bracket can introduce coolant or other media when necessary to assist in cooling the braking components, further improving braking performance and reliability, especially under long-term or high-intensity braking conditions.

[0015] Multiple heat dissipation vents on the outside of the alloy frame provide an initial channel for the dissipation of heat inside the motor.

[0028] Structural Description: 1. Wheel Hub Material Characteristics: Made of low-carbon steel, which possesses excellent strength and toughness, capable of withstanding various loads during vehicle operation, including vehicle weight, passenger and cargo weight, as well as additional forces generated during acceleration, deceleration, and turning. Its strength is sufficient to ensure that the wheel hub will not easily deform or be damaged under normal use and some harsh road conditions, providing a fundamental guarantee for vehicle driving safety. Shape and Function: It has a ring-shaped structure, which is the typical shape of a wheel hub. It is a key component connecting the disc brake motor to the vehicle wheel. The wheel is mounted on the vehicle's axle through the wheel hub, enabling the vehicle's power to be effectively transmitted to the wheel, driving the vehicle forward or achieving braking operation. At the same time, the interior of the ring-shaped wheel hub provides installation space for other components such as alloy frames and brake pads, which is an important basis for the integration and coordinated operation of the entire disc brake motor assembly.

[0029] 2. Alloy frame installation position and connection relationship: Installed inside the wheel hub 1, it is tightly fixed to the wheel hub, becoming an important support part of the internal structure of the wheel hub. It forms an integral part with the wheel hub through a fixed connection, providing a stable installation base for other components, ensuring the relative position of each component is stable during vehicle operation, and preventing loosening or displacement due to external forces such as vibration and bumps. Heat dissipation function: Multiple heat dissipation vents 3 are opened on its exterior. These vents are designed to cope with the large amount of heat generated by the motor operation, especially when the disc brake is engaged. When the motor operates the disc brake, there is intense friction between the brake pads, and heat accumulates inside the motor. The heat dissipation vents 3 provide a channel for this heat to dissipate outward. The heat can be diffused from inside the motor to the surrounding environment through the heat dissipation vents 3, thereby effectively reducing the internal temperature of the motor, preventing problems such as motor performance degradation and component damage caused by overheating, and extending the service life of the motor and related components.

[0030] 3. Heat dissipation vent structure and distribution: Located on the exterior of the alloy frame 2, these vents are typically regular or irregular in shape. Their size, number, and distribution depend on the specific design of the motor and its heat dissipation requirements. Multiple heat dissipation vents 3 are evenly or regularly distributed on the outer surface of the alloy frame 2 to ensure that heat is dissipated as evenly as possible from these openings when the motor generates heat, achieving a more efficient heat dissipation effect. Heat dissipation principle and function: Based on the principles of heat conduction and heat convection, when heat is generated inside the motor due to operation such as disc brakes, the heat is first conducted through the metal material of the alloy frame 2 to the vicinity of the heat dissipation vents 3. Then, due to the temperature difference between the heat dissipation vents 3 and the outside air, the heat is dissipated into the surrounding air through heat convection, thereby reducing the internal temperature of the motor and maintaining the motor in a more suitable temperature environment, ensuring the normal performance and reliability of the motor.

[0031] 4. Function of the Fixed Column Connecting Hub: The fixed column 4 is externally fixed to several important components and is a crucial connecting hub for the entire disc brake motor's internal structure. On one hand, it is fixedly connected to the alloy frame 2, providing a stable mounting position within the wheel hub 1. On the other hand, it is also fixedly connected to components such as the brake pads 5 and the disc 13, organically combining these components to ensure their accurate relative spatial positions and coordinated operation, achieving functions such as braking and heat dissipation for the motor. Force transmission path: During braking, when friction is generated between the brake pads 8 and 5, this friction is transmitted through the brake pads 5 to the fixed column 4, and then from the fixed column 4 to the alloy frame 2 and the wheel hub 1, thereby achieving braking of the vehicle wheels and slowing down or stopping the vehicle. Simultaneously, during motor operation, the fixed column 4 also plays a role in transmitting other forces. For example, when the motor generates torque, the force is also transmitted between relevant components through the fixed column 4, ensuring the normal operation of the motor.

[0032] 5. Brake Pad Material and Shape: The brake pads are ring-shaped and made of a material with high strength and good thermal conductivity. They can withstand significant braking force and effectively conduct heat during braking. The ring shape allows the brake pad 5 to fit snugly around the fixed post 4, forming a corresponding fit with the brake pad 8, ensuring uniform and stable friction during braking. Heat Dissipation Design and Function: Numerous irregularly shaped heat dissipation holes 6 are formed on the outer surface. These holes enhance the heat dissipation capacity of the brake pad 5 during braking. When the brake pad 5 rubs against the brake pad 8, generating heat, the heat is dissipated through the brake pad 5 itself... In addition to heat conduction and dissipation, the material can also dissipate heat directly into the surrounding air through these heat dissipation holes 6, effectively reducing the temperature of the brake pad 5 and preventing the performance of the brake pad 5 from deteriorating due to overheating, such as softening or deformation, thereby ensuring the stability and reliability of the braking effect. Braking function is achieved as follows: Brake pad 8 is installed on the top of the brake pad 5. During the braking process, the brake pad 8 will be in close contact with the brake pad 5 under the action of external force. Due to the certain coefficient of friction between the two, friction will be generated. This friction will be transmitted through the brake pad 5 to the fixed column 4 and other related components, ultimately achieving braking of the vehicle wheels and slowing down or stopping the vehicle.

[0033] 6. Structure and Distribution Characteristics of Heat Dissipation Holes: These holes are located on the outside of the brake pad 5 and are typically irregularly shaped (circular or elliptical). Their distribution is also irregularly distributed across the outer surface of the brake pad 5. This irregular design aims to maximize the heat dissipation area without compromising the overall strength and braking function of the brake pad 5, allowing heat to dissipate more quickly and effectively. Heat Dissipation Principle and Function: Based on the principles of heat conduction and convection, when the brake pad 5 rubs against the brake pad 8, the heat is first conducted through the material of the brake pad 5 to the vicinity of the heat dissipation holes 6. Then, due to the temperature difference between the heat dissipation holes 6 and the outside air, the heat is dissipated into the surrounding air through convection, effectively reducing the temperature of the brake pad 5 and preventing performance degradation due to overheating, thus ensuring stable and reliable braking performance.

[0034] 7. Connection and Movement of the Movable Plug: The movable plug 7 is slidably connected inside the mounting bracket 9, and is covered by a housing 12. It is also fixedly connected to the outside of the brake pad 8. During braking, when an external braking command is applied, the movable plug 7 slides in a certain direction within the mounting bracket 9, causing the brake pad 8 to move synchronously, making the brake pad 8 and brake slab 5 in close contact, thereby generating friction to achieve vehicle braking. Force Transmission and Limiting Function: The movable plug 7 plays the role of force transmission. It converts the externally applied braking command into a force that pushes the brake pad 8 to move, ensuring that the brake pad 8 can accurately contact the brake slab 5 and generate sufficient friction. At the same time, the mounting bracket 9 limits the sliding of the movable plug 7, preventing the movable plug 7 from excessively deviating or shaking during movement, ensuring that the contact between the brake pad 8 and brake slab 5 is uniform and stable, so that the braking force can be accurately transmitted and efficient braking can be achieved.

[0035] 8. Brake Pad Material Characteristics and Functions: Made of rubber, which has a good coefficient of friction, wear resistance, and elasticity. Its good coefficient of friction allows the brake pad 8 to generate sufficient friction when in contact with the brake pad 5, achieving effective braking. Wear resistance ensures that the brake pad 8 will not wear out too quickly during frequent braking, extending its service life. Elasticity buffers the impact force during braking, reducing the impact on the entire braking system and vehicle structure, improving braking smoothness and comfort. Connection and Movement: A movable plug 7 is fixedly connected to the outside of the brake pad 8. During braking, the movable plug 7 drives the brake pad 8 to move, making the brake pad 8 and brake pad 5 in close contact. When the vehicle needs to brake, as the movable plug 7 slides within the mounting bracket 9, the brake pad 8 accurately contacts the brake pad 5 and generates friction. Through the brake pad 5 and other related components, the braking force is transmitted to the vehicle wheels, achieving vehicle deceleration or stopping.

[0036] 9. Mounting Frame Structure and Installation Position: The mounting frame 9 is an important support structure for the entire braking system. It has internal holes for sliding connections of components such as the movable plug 7 and the telescopic rod 10. An external fluid inlet pipe 11 is fixedly connected to it. The mounting frame 9 itself is installed in the corresponding position on the motor, providing a mounting base and support for other components in the braking system. Functional Achievement: During braking, the mounting frame 9 limits and guides the sliding of the movable plug 7 and the telescopic rod 10 through its internal holes, ensuring that the movable plug 7 and the telescopic rod 10 can move in a predetermined manner. This ensures uniform and stable contact between the brake pad 8 and the brake disc 5, achieving efficient braking. Simultaneously, the externally connected fluid inlet pipe 11 can introduce coolant or other media when necessary to provide auxiliary cooling for the braking components, further improving braking performance and reliability, especially under long-term or high-intensity braking conditions.

[0037] 10. Connection and Movement of Telescopic Rod: The telescopic rod 10 is slidably connected in the hole inside the mounting bracket 9. One end of it may have a connection with related components, such as the brake pad 8 or other structures. The specific connection needs to be based on the detailed design of the motor. During braking, the telescopic rod 10 will extend and retract according to the movement of the movable plug 7 and the brake pad 8, playing an auxiliary adjustment and limiting role. Function: The telescopic rod 10 mainly plays an auxiliary adjustment and limiting role for the movement of the brake pad 8. When the movable plug 7 drives the brake pad 8 to move, the telescopic rod 10 can extend and retract as needed to prevent the brake pad 8 from excessive displacement or shaking, ensuring uniform and stable contact between the brake pad 8 and the brake lining 5, so that the braking force can be accurately transmitted and efficient braking can be achieved. At the same time, the telescopic rod 10 can also adapt to different braking conditions to a certain extent, such as when the vehicle is bumpy or the braking intensity changes, to ensure the stability and reliability of the braking system.

[0038] 11. Connection and function of infusion tube: The infusion tube 11 is open and fixedly connected to the external infusion line. It is externally fixedly connected to the mounting bracket 9. Its main function is to introduce media such as coolant when necessary to provide auxiliary cooling for the braking components. For example, under long-term or high-intensity braking conditions, the braking components will generate a lot of heat. By introducing coolant through the infusion tube 11, the temperature of the braking components can be quickly reduced, preventing the performance of the braking components from deteriorating due to overheating, and further improving braking performance and reliability.

[0039] 12. The outer casing provides protection and support: The outer casing 12 is fitted over the movable plug 7. It protects the movable plug 7 and prevents external factors from damaging it, such as preventing dust and moisture from entering the sliding area of ​​the movable plug 7 and affecting its normal movement. At the same time, the outer casing 12 also provides a certain degree of support for the movable plug 7, making the sliding of the movable plug 7 within the mounting bracket 9 more stable and ensuring the normal operation of the braking system. 13. Disc Connection and Installation Position: A groove is provided in the center of the disc 13, which is fixedly connected to the outside of the fixing post 4. It is located in a specific position inside the motor. The disc 13 is connected to the alloy frame 2 and other components through the fixing post 4, becoming part of the internal structure of the motor. It works in conjunction with related components such as the heat dissipation component to realize the heat dissipation function of the motor. Functional realization: On the one hand, the disc 13 serves as part of the heat dissipation component, with a semiconductor chip 14 fixedly connected inside its groove, participating in the heat dissipation process of the motor. On the other hand, the disc 13 may also play a certain auxiliary role in other aspects, such as force transmission or structural stability. The specific function may vary depending on the detailed design of the motor, but in general, it is to promote the coordinated work of various components inside the motor to achieve normal operation and good performance of the motor.

[0040] 14. Heat dissipation principle and function of semiconductor chip: Semiconductor chip 14 is fixedly connected in the groove outside the disk 13. It achieves heat dissipation based on the Peltier effect. The Peltier effect refers to the phenomenon that heat absorption and heat release will occur at its two ends when current passes through a semiconductor material. Semiconductor chip 14 utilizes this effect. When the motor disc brake generates a lot of heat, one side of it will absorb heat, mainly from the braking area such as the brake pads 5 and 8. Then, it will transfer this heat to the other side and dissipate it through heat conduction and other means. This effectively reduces the temperature of the braking components, prevents the performance of the braking components from deteriorating due to overheating, and ensures the stability and reliability of the braking effect. At the same time, it also helps to maintain the internal temperature of the motor within a reasonable range and ensure the normal operation of the motor.

[0041] 15. Connection and installation position of the connecting ring: The connecting ring 15 is an annular iron sheet with a bracket fixedly connected to its exterior. The connecting ring 15 is connected to the frame 16 and other components through its external bracket, and it is fixedly connected to the exterior of the disc 13, becoming part of the internal structure of the motor. It works in conjunction with other components to achieve functions such as heat dissipation of the motor.

[0042] Functional implementation: The connecting ring 15 mainly serves as a connector and support. On the one hand, it connects the disc 13 and the frame 16 and other components, enabling these components to form an organic whole and facilitate collaborative work. On the other hand, the connecting ring 15 provides an installation position and support for the frame 16 through its external bracket, ensuring that the fan blades 17 inside the frame 16 can rotate stably, realizing the heat dissipation function of the motor. The heat inside the motor is carried away by the airflow generated by the rotation of the fan blades 17, further reducing the internal temperature of the motor and ensuring the normal operation of the motor.

[0043] 16. Frame Structure and Installation Position: The fan blade 17 is rotatably connected inside the frame 16. It is fixedly connected to a specific position inside the motor by a bracket outside the connecting ring 15. The frame 16 provides the fan blade 17 with rotation space and installation foundation, enabling the fan blade 17 to rotate stably within the frame 16 and realize the heat dissipation function of the motor. Functional realization: During the operation or braking of the motor, the internal temperature of the motor may be monitored by means of temperature sensors, etc. The fan blade 17 will rotate within the frame 16 to generate a forced air cooling effect. When the fan blade 17 rotates, it accelerates the airflow around the motor, quickly carrying away the heat emitted by the semiconductor chip 14 and other parts, further reducing the internal temperature of the motor and ensuring the normal operation of the motor.

[0044] 17. Fan Blade Connection and Movement: The fan blade 17 is internally fixed to the outside of the bracket and connected to the frame 16 through the bracket, allowing the fan blade 17 to rotate stably within the frame 16. During motor operation or braking, the fan blade 17 will start rotating according to the internal temperature of the motor, generating a forced air cooling effect. The heat dissipation function is achieved by accelerating the airflow around the motor when the fan blade 17 rotates, quickly carrying away the heat emitted by the semiconductor chip 14 and other parts, further reducing the internal temperature of the motor and ensuring the normal operation of the motor. This forced air cooling method, combined with other heat dissipation methods such as heat dissipation vents and semiconductor chips, forms a relatively complete heat dissipation system, effectively dealing with the large amount of heat generated by the motor during disc braking and ensuring the normal operation of the motor and braking system.

[0045] Working principle: When the vehicle needs to brake, the braking signal is transmitted to the disc brake motor braking system. The device outside the mounting bracket 9 starts to work, pushing the movable plug 7 to slide along the hole inside the mounting bracket 9. The movable plug 7 is fixedly connected to the brake pad 8, so the brake pad 8 will move closer to the brake lining as the movable plug 7 moves. The brake pad 8 is made of rubber. When the brake pad 8 contacts the brake pad 5, which is shaped like an iron ring, friction is generated due to the coefficient of friction between rubber and metal. As the braking force is continuously applied, the friction between the brake pad 8 and the brake pad 5 gradually increases. The brake pad 5 is fixed on the fixing post 4. 4 is connected to the alloy frame 2, which is installed inside the wheel hub 1. Therefore, this friction will prevent the wheel hub 1 from rotating, thereby slowing down the vehicle. During braking, the heat dissipation holes 6 on the outside of the brake pad 5 and the elasticity of the brake pad 8 can help dissipate heat and buffer impact, ensuring braking stability. At the same time, the telescopic rod 10 inside the mounting bracket 9 can limit the movement of the brake pad 8, ensuring uniform and stable contact between the brake pad 8 and the brake pad 5, so that the braking force can be accurately transmitted and achieve efficient braking. During the motor disc brake process, the friction between the brake pad 5 and the brake pad 8 generates a lot of heat. The small heat dissipation holes 6 on the motor 5 first function, allowing some heat to be directly dissipated into the surrounding air. At the same time, the heat dissipation vents 3 on the alloy frame 2 also start working, allowing heat to diffuse from inside the motor to the outside through these vents 3. The semiconductor chip 14 fixed in the groove outside the disc 13 starts working. Based on the Peltier effect, one side of the semiconductor chip 14 absorbs heat and the other side releases heat. It mainly absorbs heat from the braking area and transfers this heat from the lower temperature side to the higher temperature side, thereby reducing the temperature of the braking components. The bracket outside the connecting ring 15 is fixedly connected to the frame 16. The fan blades 17 inside the frame 16 start rotating when the motor is running or according to the temperature sensor signal. When the fan blades 17 rotate, they accelerate the airflow around the motor, quickly carrying away the heat released by the semiconductor chip 14 and the heat emitted from other parts. At the same time, if the infusion pipe outside the mounting bracket 9 is connected to a cooling medium such as coolant, it can also provide auxiliary cooling for the braking components, further enhancing the heat dissipation effect. The entire heat dissipation process is a collaborative process. Through the combination of multiple heat dissipation methods, the temperature of the motor during disc braking is effectively reduced, ensuring the normal operation of the motor and the braking system.
