Description

Technical Field

[0001] This utility model relates to the technical field of automotive braking system components, and in particular to an anti-lock braking system with enhanced heat dissipation performance. Background Technology

[0002] In modern automotive braking systems, the anti-lock braking system (ABS) plays a crucial role, improving vehicle safety and handling by preventing wheel lock-up during braking. However, with advancements in vehicle performance and the diversification of driving conditions, braking systems generate significant heat under intensive use. This not only affects braking performance but may also shorten the lifespan of braking components and even pose safety hazards.

[0003] During operation, the friction between the brake pads and brake discs generates high temperatures, especially under prolonged or frequent braking conditions, such as driving on mountain roads or high-speed emergency braking. If this heat cannot be effectively dissipated, it will lead to brake performance degradation (thermal fade), thereby affecting driving safety. In high-temperature environments, the performance stability of automotive brake wheel speed sensors faces severe challenges. Extreme temperatures accelerate the aging of internal sensor components, leading to decreased signal transmission accuracy, and even causing signal distortion or interruption. This not only affects the response speed and control accuracy of the braking system but also directly relates to the safety and stability of vehicle operation.

[0004] In order to solve the above-mentioned technical problems, this utility model designs an anti-lock braking system with enhanced heat dissipation performance. Utility Model Content

[0005] This invention provides an anti-lock braking system with enhanced heat dissipation performance, aiming to solve the problem of insufficient heat dissipation during emergency braking in existing vehicles, leading to a decrease in braking performance. The technical solution is as follows:

[0006] An anti-lock braking system with enhanced heat dissipation performance includes a wheel hub, a brake disc, a wheel speed sensor, an ABS gear ring, and a brake caliper. The wheel hub is used to mount a wheel and is connected to the vehicle suspension system. The brake disc is connected to the wheel hub, a steering knuckle is mounted on the wheel hub, the brake caliper is connected to the steering knuckle, the ABS gear ring is mounted on the wheel hub, and at least one wheel speed sensor is provided on the steering knuckle. The detection end of the wheel speed sensor is aligned with the ABS gear ring. The ABS gear ring includes a base ring and teeth, with the teeth located at the top of the base ring.

[0007] Based on the above technical solution, it also includes an electronic control unit for processing signals from the wheel speed sensor and controlling the braking system to prevent wheel lock-up.

[0008] Furthermore, a lubricating layer is provided between the wheel hub and the ABS gear ring to reduce friction and wear.

[0009] Preferably, a heat dissipation channel is provided on the bottom ring.

[0010] Beneficial effects

[0011] Compared with existing technologies, the beneficial effects of this invention are: improved safety: By optimizing the design of the ABS gear ring and brake disc, more accurate speed signal transmission is ensured, enabling the electronic control unit to more effectively prevent wheel lock-up and improving vehicle stability and handling during emergency braking. The integrated temperature monitoring device can issue timely warnings when abnormally high temperatures are detected, helping the driver take measures to avoid heat fade and further ensuring driving safety. Enhanced system reliability: Temperature monitoring data can serve as an important basis for fault diagnosis, helping maintenance personnel quickly locate and solve problems, thus enhancing the reliability and maintainability of the system.

[0017] The present invention will be further described below with reference to the accompanying drawings and examples:

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figure 1 As shown, an anti-lock braking system with enhanced heat dissipation performance is characterized by comprising a wheel hub 1, a brake disc 2, a wheel speed sensor 4, an ABS gear ring 5, and a brake caliper 6; the wheel hub 1 is used to mount the wheel and is connected to the vehicle suspension system, the brake disc 2 is connected to the wheel hub 1, a steering knuckle 3 is mounted on the wheel hub 1, the brake caliper 6 is connected to the steering knuckle 3, the ABS gear ring 5 is mounted on the wheel hub 1, at least one wheel speed sensor 4 is provided on the steering knuckle 3, the detection end of the wheel speed sensor 4 is aligned with the ABS gear ring 5, and the ABS gear ring 5 includes a base ring 51 and teeth 52, with the teeth 52 located at the top of the base ring 51.

[0022] Traditional gear rings have their teeth located on the side of the bottom ring. This side-mounted tooth design is not conducive to the passage of airflow from natural convection or forced ventilation.

[0023] like Figure 2 and Figure 3 As shown, tooth 52 is located at the top of the bottom ring 51. This top-positioning of tooth 52 allows for better utilization of natural convection. When the vehicle is moving, the oncoming airflow can more directly impact the surface of tooth 52, thus carrying away more heat. This helps improve the overall heat dissipation efficiency of the ABS tooth ring.

[0024] Preferably, the surface of the ABS toothed ring 5 is specially treated, such as anodizing or nickel plating, to enhance corrosion resistance and wear resistance without affecting heat dissipation performance.

[0025] It also includes an electronic control unit (ECU) for processing signals from the wheel speed sensors 4 and controlling the braking system to prevent wheel lock-up. The ECU monitors the speed of each wheel in real time and reacts quickly when it detects impending lock-up, adjusting braking force rapidly to avoid it. This significantly improves vehicle stability and handling during emergency braking, reducing the risk of skidding or loss of control.

[0026] A lubricating layer is provided between the wheel hub 1 and the ABS gear ring 2 to reduce friction and wear. This lubricating layer significantly reduces the frictional force generated during the relative movement between the wheel hub 1 and the ABS gear ring 2, thereby reducing energy loss. This means that more braking energy can be effectively converted into braking force instead of being wasted on frictional heat. With reduced frictional resistance, the rotation of the ABS gear ring 2 is smoother, allowing the wheel speed sensor to capture wheel speed changes more quickly and accurately, thus improving the response speed and accuracy of the entire ABS system.

[0027] like Figure 4 As shown, heat dissipation channels 511 are formed on the bottom ring 51. The heat dissipation channels 511 increase the surface area of ​​the bottom ring 51 with air, thereby improving heat exchange efficiency. More heat can be carried away through these channels, reducing the overall temperature of the bottom ring 51. The heat dissipation channels 511 can guide airflow through the interior of the bottom ring 51 or along its surface, enhancing the effects of natural convection and forced convection, further improving heat dissipation performance.

[0028] The teeth 52 are rectangular or trapezoidal in shape. Rectangular and trapezoidal teeth have well-defined and straight edges, which helps the wheel speed sensor more accurately capture the passing signal of each tooth, thus providing more precise speed information to the electronic control unit. This high precision is crucial for the proper functioning of the anti-lock braking system (ABS).

[0029] The rectangular and trapezoidal tooth design helps guide airflow through the spaces between the teeth, enhancing natural convection and promoting heat dissipation. In particular, the trapezoidal teeth can create more open space at the top, which is beneficial for air circulation.

[0030] It also includes a temperature monitoring device, integrated into the ABS gear ring 5 or brake disc 2, for real-time monitoring of temperature changes. By monitoring temperature changes in real time, the temperature monitoring device can issue a warning when the temperature of the brake disc 2 or ABS gear ring 5 is too high, helping the driver to take timely measures such as slowing down or stopping, avoiding brake performance degradation and heat fade caused by overheating, thereby improving driving safety.

[0031] Cooling channels are provided on the brake disc 2. The cooling channels can be formed during the casting or forging process of the brake disc 2.

[0032] Cooling channels can be arranged radially along the brake disc 2, extending from the center of the brake disc 2 to the outer edge. This arrangement helps to quickly conduct heat from the central area of ​​the brake disc, which is usually the area with the highest heat concentration, to the outer edge, and then remove it through external airflow.

[0033] The cooling channel can also be spiral-shaped, allowing the cooling medium, such as air or liquid, to cover more surface area as it flows through the channel, thereby more effectively absorbing and removing heat.

[0034] The inlet of the cooling channel is located on the non-friction surface side of the brake disc 2, or near the wheel hub, to facilitate the introduction of cooling medium. The outlet is located near the outer edge of the brake disc 2, so that the heated medium can be kept away from the brake surface to avoid affecting braking performance.

[0035] The ABS toothed ring 5 rotates with the wheel hub 1, providing a signal to the wheel speed sensor 4. When the sensor detects a sudden decrease in the speed of a wheel, the electronic control unit (ECU) quickly adjusts the braking force of that wheel, applying and releasing braking force rapidly through the brake disc 2 and brake caliper 6 according to electronic control.

[0036] Temperature Monitoring and Feedback: A temperature monitoring device integrated into the ABS gear ring 5 or brake disc 2 monitors the temperature changes of critical components in real time. This device can detect localized overheating and feed the data back to the ECU. Based on the temperature monitoring data, the ECU can dynamically adjust the braking strategy, such as reducing braking force or triggering the cooling system, to prevent brake performance degradation or other problems caused by high temperatures.

[0037] When the driver presses the brake pedal, the hydraulic piston in the brake caliper 6 pushes the brake pad to clamp the brake disc 2, generating friction to slow the vehicle down. The ECU determines whether wheel lock-up is possible based on signals from the wheel speed sensors. If it detects that a wheel is about to lock up, the ECU quickly adjusts the braking force on that wheel, maintaining wheel rotation by rapidly releasing and applying pressure to prevent lock-up, thereby maintaining the vehicle's directional stability and handling.

[0038] The brake disc 2 is designed with heat dissipation channels inside. These channels can guide airflow through natural convection or forced ventilation to remove the heat generated by friction and ensure that the surface temperature of the brake disc is kept within a reasonable range.

[0039] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
