Description

Technical Field

[0001] This utility model relates to the field of braking, and in particular to a wheel system braking device. Background Technology

[0002] In existing cutting equipment, multiple guide wheels are typically used to guide the cutting line in order to perform the cutting operation on the workpiece. Only one guide wheel acts as the driving wheel, driven by a motor and braked by the motor's braking mechanism. The remaining guide wheels are driven wheels, rotating along with the cutting line during the cutting process. However, with the development of cutting technology, cutting speeds are constantly increasing to improve production efficiency. In this case, the faster the cutting speed, the greater the rotational inertia of the guide wheels, and the increased number of guide wheels further increases the total inertia that needs to be overcome during braking. Currently, braking of the driven wheels relies solely on friction between the cutting line and the guide wheels. This method has several problems at high speeds. On the one hand, higher cutting speeds intensify friction between the cutting line and the guide wheels, leading to severe friction, excessive wear on the cutting line, and rapid wear on the guide wheel surface, reducing the lifespan of the guide wheels. On the other hand, friction-based deceleration has poor braking effect at high speeds, requiring a long braking time, affecting the overall performance and operational efficiency of the equipment, and potentially causing safety hazards, failing to meet the requirements for efficient, safe, and stable cutting equipment operation.

[0019] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0020] Please refer to Figure 1 as well as Figure 2 A wheel system braking device includes an axle 1, a brake disc 2, a housing 3, and a magnetic component 4; the axle 1 is rotatably connected to the housing 3, and the brake disc 2 is fixedly connected to one end of the axle 1 along its length; the magnetic component 4 is fixedly connected to the housing 3, and at least part of the magnetic component 4 is disposed opposite to the brake disc 2; the brake disc 2 can be magnetized under the magnetic field of the magnetic component 4.

[0021] As described above, the beneficial effects of this utility model are as follows: the wheel system braking device achieves braking of the wheel axle 1 through the interaction between the magnetic component 4 and the brake disc 2, exhibiting significant braking efficiency and reliability. Firstly, the wheel axle 1 is rotatably connected to the housing 3, and the brake disc 2 is fixed to one end of the wheel axle 1, thus ensuring synchronous rotation of the wheel axle 1 and the brake disc 2. During braking, the magnetic field generated by the electromagnet or magnetic conductor can magnetize the brake disc 2, forming a strong magnetic force, thereby enabling the interaction force between the brake disc 2 and the magnetic component 4 to exert a braking effect. Compared to traditional mechanical friction braking, magnetic braking offers higher precision and response speed. At high speeds, friction braking can lead to overheating and wear, while magnetic braking effectively avoids these problems, extending the equipment's service life. Simultaneously, magnetic braking has a faster response speed, significantly shortening deceleration time and improving the equipment's operating efficiency.

[0022] In some embodiments, the magnetic element 4 is an electromagnet.

[0023] As described above, when the magnetic component 4 is an electromagnet, more precise braking control can be achieved. The current of the electromagnet can be precisely controlled, thereby adjusting the strength of the magnetic field and consequently the braking torque. This flexibility provides optimized conditions for braking under different operating conditions. The application of electromagnets also enables more intelligent control of the device, such as automatically adjusting braking parameters through an electronic control system and dynamically adjusting them according to actual needs and operating status. Therefore, electromagnets not only improve braking efficiency but also provide different levels of braking force as needed under different operating conditions, meeting the braking requirements under different loads.

[0024] Specifically, the number of magnetic elements 4 is at least two, and the magnetic elements 4 are arranged circumferentially around the axis of the wheel axle 1.

[0025] As described above, by adding multiple electromagnets and arranging them in a specific pattern (such as circumferentially distributed around the axis of wheel axle 1), the braking force can be evenly distributed, avoiding localized overheating or uneven wear that may occur during concentrated braking. This distribution effectively improves the stability and reliability of the system and helps optimize the braking effect. The use of multiple electromagnets not only increases the total braking power but also maintains a more stable mechanical state during deceleration through a reasonable layout, avoiding mechanical vibration or noise caused by uneven braking. Compared to a single electromagnet, this multi-electromagnet braking system is more adaptable to high-speed and high-load working environments, greatly improving the applicability and long-term operational stability of the equipment. Preferably, the number of electromagnets ranges from 2 to 8. Preferably, the number of electromagnets is an even number, such as 2, 4, 6, or 8, because an even number of guide wheels makes it easier to achieve a balanced relationship, which helps enhance the stability of the braking process.

[0026] In some embodiments, the housing 3 includes a fixed panel 31 and a bearing seat 32; the fixed panel 31 is fixedly connected to the bearing seat 32, and both the fixed panel 31 and the bearing seat 32 are rotatably connected to the wheel axle.

[0027] As described above, the structural design of the housing 3 includes a fixed panel 31 and a bearing seat 32, making the entire system more stable and effectively supporting and fixing the wheel axle 1. The fixed panel 31 and the bearing seat 32 have several possible positional relationships; for example, the fixed panel can be positioned close to the brake disc or far from the brake disc.

[0028] Specifically, the brake disc 2 is disposed between the magnetic component 4 and the fixed panel 31.

[0029] As described above, the design of the brake disc 2 positioned between the magnetic component 4 and the fixed panel 31 optimizes the range of the magnetic field, ensuring that the electromagnet's magnetic force can effectively act on the brake disc 2. Because the distance between the magnetic component 4 and the brake disc 2 is just right, it avoids interference during normal operation while ensuring sufficient attraction during braking, allowing the brake disc 2 to respond quickly to changes in the magnetic field. This structural optimization effectively improves the braking response speed, ensuring that the equipment can complete the deceleration process in a short time. Furthermore, the appropriate position of the brake disc 2 also helps with heat dissipation, reducing heat accumulation during braking and helping to extend the service life of the electromagnet and the brake disc 2.

[0030] In some embodiments, the gap between the magnetic element 4 and the brake disc 2 is in the range of 1-2 mm.

[0031] As described above, a gap range of 1-2 mm is set to ensure that there is no interference between the magnetic component 4 and the brake disc 2 during normal operation, while simultaneously generating sufficient attraction for effective braking. This design optimizes the braking effect, ensuring safety while avoiding wear and heat accumulation caused by excessive contact and friction. The reasonable control of the gap not only improves the efficiency of the magnetic field but also reduces friction and unnecessary heat generation, thereby extending the lifespan of each component and improving the stability and durability of the system. This meticulous design demonstrates its superior durability in long-term operation and reduces maintenance costs. Preferably, the gap between the magnetic component 4 and the brake disc 2 is 1 mm.

[0032] In some embodiments, the axle 1 and the brake disc 2 are arranged concentrically.

[0033] As described above, concentrically positioning the wheel axle 1 and brake disc 2 ensures synchronized movement between them during operation. This design optimizes the overall stability of the braking system, avoiding eccentric torque or vibration caused by misalignment. This precise alignment allows the braking system to maintain balance at high speeds, reducing noise and vibration, and improving operational comfort and safety. Furthermore, the concentric positioning reduces wear between the brake disc 2 and the magnetic component 4, further extending the system's lifespan.

[0034] In some embodiments, a guide wheel 5 is also included, which is located at the end of the axle 1 away from the brake disc 2 and is detachably connected to the axle 1.

[0035] As can be seen from the above description, since the guide wheel is a functional component of the entire wheel and axle assembly, it needs to be in direct contact with external facilities, resulting in a high wear rate. For example, the guide wheel rubber strip needs to be replaced in a timely manner to meet the working requirements. Therefore, the guide wheel is designed to be detachably connected to the wheel and axle to facilitate the replacement of the guide wheel.

[0036] In some embodiments, the brake disc 2 is keyed, interference-fitted, or flanged to the wheel axle 1.

[0037] As described above, keyed connections, interference fits, and flange connections all ensure a strong and stable connection between the brake disc 2 and the axle 1. These connection methods effectively transmit torque, ensuring that the brake disc 2 and the axle 1 rotate synchronously during operation. Especially under high-speed or high-load conditions, these connection methods prevent loosening or slippage between the brake disc 2 and the axle 1, ensuring the stable operation of the braking system. A stable connection also helps improve equipment reliability and reduces malfunctions or equipment downtime caused by loosening.

[0038] In summary, the wheel braking device provided by this utility model achieves efficient and precise braking through the interaction between the magnetic component and the brake disc, significantly improving the braking efficiency and reliability of the equipment. Compared with traditional friction braking methods, this device utilizes the magnetization process under the action of a magnetic field, avoiding overheating and wear problems and extending the service life of the equipment. The application of electromagnets allows the braking effect to be achieved through precise adjustment of the current, thereby providing stable braking torque under different working conditions, ensuring excellent braking performance under different loads and operating conditions, and improving the adaptability and flexibility of the system. In addition, electromagnets can also cooperate with electronic control systems to achieve intelligent control and automatically adjust braking parameters, further improving the accuracy of operation.

[0039] In this device, multiple electromagnets are evenly distributed circumferentially around the wheel axle, avoiding localized overheating or uneven wear caused by concentrated braking, thus improving the uniformity and stability of the braking effect. This design not only reduces mechanical vibration or noise caused by uneven braking, but also enables the equipment to maintain efficient and stable operation under high speed and high load, enhancing the system's reliability and long-term operational stability.

[0040] In terms of structural design, the fixed panel and bearing housing of the housing ensure stable support and fixation of the wheel axle, improving the overall stability of the system. The brake disc is strategically positioned between the magnetic component and the fixed panel, optimizing the range of the magnetic field and ensuring that the electromagnet can efficiently act on the brake disc, thereby improving braking response speed. By setting a reasonable gap of 5-15 mm, interference between the magnetic component and the brake disc is avoided, while generating sufficient attraction during braking, enhancing the stability and durability of the system.

[0041] The device also employs keyed connections, interference fits, or flange connections to ensure a strong connection between the brake disc and the axle, effectively transmitting torque and preventing loosening or slippage under high-speed, high-load conditions, thus guaranteeing stable equipment operation. These connection methods are designed to adapt to various working environments, ensuring stable operation of the equipment under conditions of high temperature, high load, and vibration.
