Description

Technical Field

[0001] This invention relates to the field of electronic parking caliper technology, and more specifically, to an integrated electronic parking brake caliper. Background Technology

[0002] The existing integrated electronic parking brake caliper integrates the drive motor, reduction mechanism and other components into the brake caliper body. It can realize parking braking through electronic control. However, when such calipers are applied to extremely harsh and continuously high-load industrial scenarios, their conventional design has inherent limitations in dealing with complex and comprehensive working conditions.

[0003] On equipment such as flatbed trucks in coastal ports in northern China, the braking system operates under extremely harsh conditions during winter. Frequent heavy-load braking causes the brake discs to reach extremely high temperatures. Sea salt in the air and chlorides from de-icing agents on the road surface repeatedly sinter at high temperatures, forming a dense and heat-insulating salt-etched hard shell on the surface of the brake discs, which weakens braking performance and heat dissipation. However, the salt-etched hard shell cannot be effectively removed by simply spraying it with pure water. It often requires manual downtime for several hours for acid washing, which severely interrupts continuous operation.

[0004] Existing caliper architectures typically separate cooling and cleaning functions, providing only physical cooling while chemical cleaning relies entirely on manual intervention outside the vehicle. This segmented approach makes it impossible to perform preventative maintenance during vehicle operation intervals, and it is difficult to meet the specialized job requirements in extremely harsh and continuously high-load industrial scenarios. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide an integrated electronic parking brake caliper, which aims to solve the above-mentioned technical problems.

A second friction plate is disposed on one side of the driving cavity, which is opposite to the first friction plate, so as to drive the first friction plate and the second friction plate to fit together to clamp the vehicle brake disc and complete the parking brake. The cooling cavity is equipped with two sets of opposing first heat dissipation units to store coolant, and a second heat dissipation unit linked to the output end of the drive cavity is also configured in the middle of the two sets of opposing first heat dissipation units to perform secondary cooling on the coolant. The caliper frame module has a detergent mixing mechanism located inside, near the second friction plate.

The fourth conveying hose on the independent cavity at the head end of the semi-circular annular storage bottle extends outward to connect to the heat dissipation partition plate, and the fourth conveying hose on the independent cavity at the tail end of the semi-circular annular storage bottle extends into the interior of the second storage cavity.

[0013] As a further aspect of the present invention: the first heat dissipation unit further includes several toothed arc edges fixedly connected to the independent cavity sidewalls on both sides of the semi-circular annular storage bottle, and each toothed arc edge is provided with a frame-shaped conductor. A magnetic block is fixedly installed on the side of the frame-shaped conductor, and the magnetic block is attracted and corresponds to the magnetic coating block of the magnetic cooling liquid arc cavity through the sidewall of the semi-circular annular storage bottle. A bevel gear is movably installed on the side of the frame-shaped conductor away from the magnetic block. A track sleeve is linked to the side of the bevel gear, and the bevel gear meshes with the toothed arc edge. Two first heat dissipation fan rods are assembled on the track sleeve to rotate with the rotation of the track sleeve.

[0014] As a further aspect of the present invention: the first heat dissipation unit further includes several heat exchange mechanisms fixedly connected to the side wall of the partition plate.

[0017] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects: (1) This solution integrates braking drive, active cooling and online chemical cleaning functions into the caliper body to build an integrated thermal management and maintenance system, solving the problem that the dense salt corrosion hard shell formed on the surface of the brake disc due to high-temperature sintering of sea salt and chloride de-icing agent under extreme working conditions cannot be removed online. The integrated cleaning agent mixing mechanism can use the heat generated during the driving process to preheat the special chemical cleaning agent and mix it with the warm coolant from the cooling system to generate an active cleaning solution. This solution can be automatically sprayed onto the surface of the brake disc during vehicle operation intervals through the built-in drive pump and nozzle, realizing the online dissolution and removal of the salt corrosion hard shell. This avoids the interruption of operation caused by the traditional method of relying on long-term manual downtime for acid washing.

[0018] (2) While the single main drive motor of the drive mechanism outputs braking torque, its tail end output synchronously drives the second heat dissipation unit in the cooling cavity through the mechanical transmission chain, providing forced stirring and heat exchange power for the coolant, so that the heat dissipation intensity can be dynamically matched with the braking load. At the same time, the heat generated by the operation of the drive components and the braking waste heat recovered by the cooling system are directed and used to preheat the cleaning agent and maintain the temperature of the mixture, creating the necessary thermal environment for chemical cleaning.

[0022] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0023] The integrated electronic parking brake caliper provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0024] like Figures 1 to 9 As shown, this embodiment of the invention provides an integrated electronic parking brake caliper, including an assembly main housing 1. A caliper frame module 2 is disposed on the side of the assembly main housing 1, and a heat dissipation baffle 6 is provided through the caliper frame module 2. A first friction plate 10 is disposed on the surface of the heat dissipation baffle 6. A drive mechanism 3 is disposed on the side of the caliper frame module 2. The drive mechanism 3 includes a drive cavity 31 and a cooling cavity 32. A second friction plate 11 is disposed on one side of the driving cavity 31, which is opposite to the first friction plate 10, so as to drive the first friction plate 10 and the second friction plate 11 to fit together to clamp the vehicle brake disc and complete the parking brake. The cooling cavity 32 is equipped with two sets of opposing first heat dissipation units 33 to store coolant respectively, and a second heat dissipation unit 38, which is linked to the output end of the drive cavity 31, is also configured in the middle of the two sets of opposing first heat dissipation units 33 to perform secondary cooling on the coolant. The caliper frame module 2 has a detergent mixing mechanism 24 located inside the caliper frame module 2 on the side near the second friction plate 11. The detergent mixing mechanism 24 includes an annular cavity shell 241 that serves as a mixing chamber and a first delivery hose 2412 for connecting the coolant, so as to use the thermal effect of the drive mechanism 3 to heat mix the coolant and detergent for maintenance.

[0025] To address the problem that existing integrated electronic parking brake calipers, under extreme high-load industrial scenarios, cannot automatically remove the chloride salt corrosion hard shell formed by high-temperature sintering on the brake disc surface during operation breaks due to the separation of cooling and cleaning functions, resulting in decreased braking performance and reliance on manual downtime acid cleaning, which severely disrupts the continuity of operations, the above-mentioned technical solution is adopted. The above-mentioned technical solution mainly consists of an assembly main housing 1, a caliper frame module 2, a heat dissipation baffle 6, a drive mechanism 3, a first friction plate 10, a second friction plate 11, a first heat dissipation unit 33, a second heat dissipation unit 38, and a cleaning agent mixing mechanism 24.

[0026] The main assembly housing 1 serves as the load-bearing and mounting base for the entire brake caliper. Made of high-strength alloy, it possesses excellent structural rigidity and corrosion resistance, and is used to integrate and mount various functional modules. The caliper frame module 2 is fixedly connected to the side of the main assembly housing 1, forming the main frame of the caliper. Its interior contains a cavity structure for accommodating friction pads, heat dissipation, and cleaning components. A heat dissipation baffle 6 is located on one side of the open end of the caliper frame module 2. The first friction pad 10 is fixedly mounted on its surface. The heat dissipation baffle 6 itself has heat conduction and structural support functions, used to dissipate the heat generated by the friction pads during braking and participate in the cooling cycle. The configured drive mechanism 3 is located on the side of the caliper frame module 2, including a drive cavity 31 and a cooling cavity 32. The drive cavity 31 is used to accommodate the drive component that provides braking force output, while the cooling cavity 32 is used to accommodate the active heat dissipation component. A second friction plate 11 is arranged on one side of the drive cavity 31. The second friction plate 11 is arranged opposite to the first friction plate 10 on the heat dissipation baffle 6. Under the action of the drive mechanism 3, the first friction plate 10 and the second friction plate 11 can be driven to move inward and fit tightly together, thereby clamping the vehicle's brake disc and realizing the parking brake function.

[0027] Specifically, the two sets of opposing first heat dissipation units 33 arranged inside the cooling cavity 32 are used to store and circulate coolant to perform initial cooling of the braking system. The second heat dissipation unit 38, located in the middle of the two sets of first heat dissipation units 33, has its driving end linked with the output end of the driving cavity 31. This allows the mechanical energy generated during the braking process to simultaneously perform secondary enhanced cooling of the coolant flowing through the first heat dissipation unit 33, thereby improving the energy efficiency and heat dissipation capacity of the cooling system.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the caliper frame module 2 includes a cavity-type housing 21 fixedly connected to the main housing 1. A first storage cavity 22 is formed inside the cavity-type housing 21 near the first friction plate 10, and a second storage cavity 23 is formed inside the cavity-type housing 21 near the second friction plate 11. The outer surface of the cavity-type housing 21 is U-shaped with a heat dissipation baffle 6 fixedly connected to one side of the inner wall at the opening end. A cylindrical recess is formed on the inner wall at the other side of the opening end, and a linkage direct drive module 4 is assembled through the recess. The outer surface of the linkage direct drive module 4 is in close contact with the second storage cavity 23.

[0029] The first storage chamber 22 is located near the first friction plate 10, while the second storage chamber 23 is located near the second friction plate 11. The first storage chamber 22 and the second storage chamber 23 are connected to allow the hose for subsequent delivery of coolant to pass through. The configured linkage direct drive module 4 is a power conversion structure in the prior art, including but not limited to the use of a motor and a planetary gear reduction mechanism. That is, the planetary gear reduction mechanism converts the high-speed, low-torque power output by the motor into low-speed, high-torque rotational power, and then converts the rotational motion into linear thrust through the lead screw and nut transmission, thereby driving the brake piston to complete the parking push or unlocking return action. The self-locking characteristic of the trapezoidal lead screw can also lock the piston to prevent the vehicle from rolling when the motor is de-energized. This is a conventional solution in the prior art for realizing EPB parking brake force amplification and motion form conversion, so it will not be described in detail here. The outer surface of the linkage direct drive module 4 is close to the second storage chamber 23 to facilitate the use of its rotational force during the torque force conversion process.

[0030] Specifically, the cavity-type housing 21 in the caliper frame module 2 serves as the main load-bearing structure of the caliper. Its U-shaped opening design accommodates the edge of the vehicle's brake disc. The heat dissipation baffle 6, located on one side of the U-shaped opening, not only mounts the first friction plate 10 but also serves as a key interface for thermal management, guiding frictional heat into the internal cooling cycle. The linkage direct drive module 4, assembled within a cylindrical recess on the other side of the U-shaped opening, has its outer surface tightly attached to the second storage cavity 23. This allows the linkage direct drive module 4, during operation, to directly transfer its mechanical or thermal energy—whether rotation or accompanying vibration and thermal radiation—to the adjacent second storage cavity 23, providing a physically tight coupling condition for the detergent mixing mechanism 24 subsequently located in this area. Although the first storage cavity 22 and the second storage cavity 23 are functionally separated, they are interconnected, forming a continuous internal channel for the flow of cooling and cleaning media. Through spatial planning and structural coupling, the movement and heat energy of the drive module can be effectively captured and utilized by adjacent functional modules, providing a physical carrier for utilizing the thermal effect of the drive mechanism 3.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the detergent mixing mechanism 24 is assembled inside the second storage cavity 23 close to the outer surface of the linkage direct drive module 4. The surface of the heat dissipation baffle 6 is fixedly connected to the first friction plate 10. The output end of the linkage direct drive module 4 is assembled with a second friction plate 11 facing the first friction plate 10. The drive cavity 31 is fixedly connected to the side of the linkage direct drive module 4 through the assembly main housing 1. The main drive motor 35 is fixedly installed inside the drive cavity 31. The main drive motor 35 has independent output ends at both ends. The output end at the beginning of the main drive motor 35 is connected to the linkage direct drive module 4. The output end at the end of the main drive motor 35 is engaged with the linkage track 36.

[0032] Specifically, the detergent mixing mechanism 24 is integrated inside the second storage cavity 23, and is arranged adjacent to the outer surface of the linkage direct drive module 4 through the cavity-type housing 21, allowing the detergent mixing mechanism 24 to sense and absorb the heat generated by the linkage direct drive module 4 during operation. The output end of the linkage direct drive module 4 is directly assembled with the second friction plate 11, which is directly opposite the first friction plate 10 fixed on the heat dissipation partition 6, forming the core braking pair for clamping the brake disc. The drive cavity 31 and its internal main drive motor 35 serve as the power source for the entire system. Its first-end output directly drives the linkage direct drive module 4 through a mechanical connection, controlling the advance and retreat of the second friction plate 11 to achieve braking and release. Its rear-end output transmits power through the linkage track 36, creating conditions for online automatic cleaning.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the cooling cavity 32 is fixedly installed in parallel at the bottom of the drive cavity 31. Both the drive cavity 31 and the cooling cavity 32 are cylindrical cavities. A first circular toothed ring 37 is movably installed at the center of the tail end of the cooling cavity 32. The linkage track 36 extends into the interior of the cooling cavity 32 and engages with the outer surface of the first circular toothed ring 37. The first heat dissipation unit 33 includes a semi-circular annular storage bottle 331. The semi-circular annular storage bottle 331 is fixedly assembled inside the cooling cavity 32, and two sets of closely attached semi-circular annular storage bottles 331 form a complete ring. A second heat dissipation unit 38 is arranged at the center of this complete ring.

[0034] The main drive motor 35 is a conventional motor used to provide stable driving force. Its output end is connected to the direct drive module 4 to provide the rotational driving force to be converted. The linkage track 36, which meshes with the output end of the main drive motor 35, extends to the center of the cooling cavity 32 and drives the first ring gear 37 to rotate. The rotation of the first ring gear 37 drives the second ring gear 381 to rotate. The cooling cavity 32 and the drive cavity 31 are parallel and cylindrical, forming a power and cooling composite module. The power output from the tail end of the main drive motor 35 is transmitted to the first ring gear 37 in the cooling cavity 32 through the linkage track 36, so that the primary drive of the cooling system comes directly from the brake drive motor, without the need for an additional independent motor. The main body of the first heat dissipation unit 33 consists of two semi-circular annular storage bottles 331, which are joined together to form a complete annular liquid storage structure and fixed in the cooling cavity 32. The space reserved in the center of this annular structure is used to accommodate the second heat dissipation unit 38. The coolant storage container, i.e., the semi-circular annular storage bottle 331, can be designed as an annular ring surrounding the second heat dissipation unit 38 of the active heat dissipation component, increasing the heat exchange area and optimizing the heat dissipation channel. Furthermore, through the gear transmission of the linkage track 36 and the first circular ring gear 37, the rotational power of the main drive motor 35 is introduced into the closed cooling cavity 32 to drive the second heat dissipation unit 38 located therein. This realizes the direct and mechanical conversion and utilization of braking power into cooling power, ensuring that whenever the braking system is working, the cooling enhancement system is also driven synchronously, so that the heat dissipation capacity can be matched with the braking load in real time.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the second heat dissipation unit 38 includes a second annular toothed ring 381 movably installed at the center of the tail end of the cooling cavity 32, and the second annular toothed ring 381 is integrally engaged with the inner ring tooth of the first annular toothed ring 37. Four parallel cold liquid conduits 382 are fixedly connected to the outer edge of the second annular toothed ring 381 in a circumferential pattern. Each cold liquid conduit 382 is fixedly connected to a magnetically attracted cold liquid arc-shaped cavity 383 on its side. The interior of the magnetically attracted cold liquid arc-shaped cavity 383 and the interior of the cold liquid conduit 382 both store cold liquid. The outer surface of the magnetically attracted cold liquid arc-shaped cavity 383 is attached to the inner wall of two sets of semi-circular annular storage bottles 331, and a magnetically coated block is provided on the attached end.

[0036] Specifically, the second heat dissipation unit 38 is used as a component to perform secondary cooling of the coolant in the first heat dissipation unit 33. Its second circular toothed ring 381 meshes with the inner ring tooth of the first circular toothed ring 37 through the inner ring tooth. Therefore, when the first circular toothed ring 37 is driven to rotate by the linkage track 36, it will synchronously drive the second circular toothed ring 381 to rotate around its axis. The four coolant conduits 382 fixed to the outer edge of the second circular toothed ring 381 and the magnetically attracted coolant arc-shaped cavity 383 on its side revolve accordingly. The outer surface of the magnetically attracted coolant arc-shaped cavity 383 is in contact with the inner wall of the semi-circular annular storage bottle 331, and the magnetically coated blocks and magnetic blocks 335 respectively provided on the contact surfaces correspond to each other, achieving non-contact coupling through magnetic force. The coolant stored inside the coolant conduit 382 and the magnetically attracted coolant arc-shaped cavity 383, as it rotates with the second annular toothed ring 381, undergoes enhanced flow and mixing of the coolant due to centrifugal force. Simultaneously, its outer wall exchanges heat with the coolant inside the semi-circular annular storage bottle 331. Gear meshing diverts the main driving power, enabling the second heat dissipation unit 38 to obtain rotational power linked to the braking action. This eliminates the need for an additional motor drive, achieving synchronous cooling enhancement and optimized energy efficiency. Through magnetic coupling rather than rigid connection, the rotating magnetically attracted coolant arc-shaped cavity 383 can transmit rotational motion and stirring effect to the interior of the storage bottle through the wall of the semi-circular annular storage bottle 331, while avoiding the sealing problem of the rotating shaft. The rotating coolant conduit 382 and the magnetically attracted coolant arc-shaped cavity 383 together form a dynamic rotating cold source, continuously sweeping across the inner wall of the semi-circular annular storage bottle 331, achieving active heat exchange of the stored coolant and improving the temperature uniformity and heat dissipation efficiency of the coolant after the initial cooling.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the second heat dissipation unit 38 also includes a servo motor 384 fixedly installed at the center of the tail end of the cooling cavity 32. The servo motor 384 is located in the inner ring of the second annular toothed ring 381. A second heat dissipation fan rod 385 is fixedly installed on the output end of the servo motor 384. A partition plate 332 is fixedly connected to the middle position of the interior of the semi-circular annular storage bottle 331. The partition plate 332 divides the interior of the semi-circular annular storage bottle 331 into two independent cavities. A fourth delivery hose 34 for drainage is fixedly installed at the bottom of the side end of each of the two independent cavities. The fourth delivery hose 34 on the independent cavity at the head end of the semi-circular annular storage bottle 331 extends outward to connect to the heat dissipation partition plate 6. The fourth delivery hose 34 on the independent cavity at the tail end of the semi-circular annular storage bottle 331 extends into the interior of the second storage cavity 23.

[0038] Specifically, to further enhance airflow and heat dissipation within the cooling cavity 32, a servo motor 384 is independently installed at the center of the inner ring of the second annular toothed ring 381. The rotation drive of this servo motor 384 is independent of that of the second annular toothed ring 381. A second cooling fan rod 385 installed at its output end generates directional airflow to force-cool the interior of the cooling cavity 32, particularly the rotating second annular toothed ring 381, the coolant conduit 382, ​​and the outer surface of the semi-circular annular storage bottle 331. The servo motor 384 is a micro-electrically controlled motor in the prior art, capable of independent start / stop and speed adjustment based on temperature sensor signals, achieving on-demand heat dissipation. The interior of the semi-circular annular storage bottle 331 is divided into two independent cavities by a partition plate 332. The independent cavity at the first end, near the heat dissipation partition plate 6, is connected to the interactive side groove 7 inside the heat dissipation partition plate 6 via a fourth delivery hose 34 at its bottom. This connection allows the delivery of the low-temperature coolant, processed by the cooling system, to the heat dissipation partition plate 6 for direct cooling of the frictional heat source. The independent cavity at the tail end, that is, the side near the second storage cavity 23, delivers the coolant that has absorbed heat and increased in temperature to the area of ​​the second storage cavity 23 through another fourth delivery hose 34 at its bottom. This prepares for subsequent detergent mixing and further circulation, realizes the directional flow and functional zoning of the coolant in the system, and ensures that the coolant can be recirculated according to heat absorption and heat dissipation. The cooling system is connected in series with the brake heat dissipation interface, that is, the surface of the heat dissipation baffle 6 and the second storage cavity 23 through pipeline connection.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the first heat dissipation unit 33 further includes several toothed arc edges 333 fixedly connected to the independent cavity sidewalls on both sides of the semi-circular annular storage bottle 331, and each toothed arc edge 333 is provided with a frame-shaped conductor 334. A magnetic block 335 is fixedly installed on the side of the frame-shaped conductor 334, and the magnetic block 335 is attracted and corresponds to the magnetic coating block of the magnetic cooling liquid arc cavity 383 through the sidewall of the semi-circular annular storage bottle 331. A bevel gear 336 is movably installed on the side of the frame-shaped conductor 334 away from the magnetic block 335. A track sleeve 337 is linked to the side of the bevel gear 336, and the bevel gear 336 meshes with the toothed arc edge 333. Two first heat dissipation fan rods 338 are assembled on the track sleeve 337 to rotate with the rotation of the track sleeve 337.

[0040] In this design, several toothed arc edges 333 are provided on the inner wall of each independent cavity of the semi-circular annular storage bottle 331. A frame-shaped conductor 334 is magnetically coupled to the magnetic coating block on the rotating magnetically attracted cool liquid arc cavity 383 on the outer side of the semi-circular annular storage bottle 331 through the magnetic attraction block 335 on it. Therefore, when the magnetically attracted cool liquid arc cavity 383 revolves with the second circular toothed ring 381, its changing magnetic field will drag the frame-shaped conductor 334 along the trajectory of the toothed arc edge 333 through magnetic attraction. During the movement, it is only necessary to control the rotation state of one end of the first circular toothed ring 37. The movement path of the frame conductor 334 is restricted by the arc-shaped tooth groove of the toothed arc edge 333. The bevel gear 336 installed on the frame conductor 334 meshes with the teeth on the toothed arc edge 333. When the frame conductor 334 is driven by magnetic force to move along the toothed arc edge 333, the bevel gear 336 rotates due to its meshing relationship with the fixed tooth groove. The side of the bevel gear 336 is linked to the track sleeve 337. The rotation of the bevel gear 336 drives the track sleeve 337 to rotate. Finally, the two first cooling fan rods 338, which are movably assembled on the track sleeve 337, rotate accordingly, stirring the liquid in the internal cavity of the semi-circular annular storage bottle 331, further improving heat dissipation.

[0041] Specifically, inside the semi-circular annular storage bottle 331, in addition to the heat exchange of the coolant itself, a forced airflow generated by the first cooling fan rod 338 is added to cool the stored coolant and the inner wall of the container. At the same time, the frame-shaped conductor 334 may also act as a heat sink during movement, increasing the heat exchange area. The entire system is powered by a single drive motor 35, which is transmitted through the linkage track 36, the first circular toothed ring 37, and the second circular toothed ring 381. Ultimately, it drives the magnetically attracted coolant arc cavity 383 to rotate and stir the external coolant, and drives the internal first cooling fan rod 338 to rotate and stir the liquid through magnetic coupling.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the first heat dissipation unit 33 also includes several heat exchange mechanisms 5 fixedly connected to the side wall of the partition plate 332. The heat exchange mechanism 5 includes a flow conduit 51 connecting both sides of the partition plate 332, and the flow conduit 51 has a cold liquid cavity 52 for storing cold liquid. Several first heat-conducting fins 53 and second heat-conducting fins 54 arranged in a circular pattern are sealed and connected to both ends of the flow conduit 51 through the cold liquid cavity 52. ​​An electrically controlled valve head 55 is fixedly installed inside the flow conduit 51. The heat dissipation partition plate 6 has an interactive edge groove 7 at the edge end, and the interactive edge groove 7 is connected to the fourth delivery hose 34 extending into the heat dissipation partition plate 6.

[0043] The heat exchange mechanism 5 is configured to facilitate efficient heat transfer between the coolant in the two independent cavities separated by the partition plate 332 and allow for the exchange of coolant on both sides under controlled conditions. The flow conduit 51 extends laterally through the partition plate 332, with its two ends extending into the independent cavities on both sides of the partition plate 332. An independent cold liquid cavity 52 is opened inside the flow conduit 51 for storing coolant. The ends of the flow conduit 51 that extend into the two cavities are respectively sealed with a number of first heat-conducting fins 53 and second heat-conducting fins 54 arranged in a circle. The first heat-conducting fins 53 are located on the side of the flow conduit 51 near the heat dissipation partition plate 6, that is, the end of the first cavity. The second heat-conducting fins 54 are located on the side near the second storage cavity 23, that is, the end of the tail cavity. Both the first heat-conducting fin 53 and the second heat-conducting fin 54 are made of high thermal conductivity materials in the prior art, including but not limited to copper and aluminum alloys. Their function is to quickly transfer the heat of the main coolant in their respective cavities to the coolant in the cold liquid cavity 52 of the flow conduit 51. The coolant in the cold liquid cavity 52 becomes a thermal bridge, which can quickly transfer heat from the cavity with a higher temperature to the cavity with a lower temperature, thereby achieving heat balance of the coolant between the two cavities and avoiding temperature unevenness caused by differences in coolant circulation path or local heat dissipation.

[0044] Inside the flow duct 51, an electronically controlled valve head 55 is fixedly installed. This valve head 55 is a miniature solenoid valve, as is common in the prior art. It is controlled by the temperature control module of the vehicle's electronic control unit. The valve head 55 can be completely closed, partially open, or fully open, thereby controlling the flow rate of coolant exchanged through the coolant cavity 52 of the flow duct 51. When there is a large temperature difference between the two cavities, the valve head 55 can be opened to allow a small amount of coolant to mix, accelerating temperature equalization. When it is necessary to maintain different temperature conditions on both sides, such as maintaining a low temperature at the front end for efficient brake disc cooling, and a certain temperature at the rear end for preheating the washer fluid, the flow can be closed or restricted to achieve temperature zone management.

[0045] An interactive groove 7 is provided at the inner edge of the heat dissipation baffle 6, which is connected to the fourth delivery hose 34 extending into the heat dissipation baffle 6. This forms a direct channel for the coolant to reach the frictional heat source, namely the back of the first friction plate 10. The low-temperature coolant flowing out from the cavity at the head end of the semi-circular annular storage bottle 331 is injected into the interactive groove 7 through the fourth delivery hose 34. Utilizing the thermal conductivity of the heat dissipation baffle 6, the cold energy carried by the coolant is efficiently transferred to the installation area of ​​the first friction plate 10, thereby achieving direct absorption and dissipation of the frictional heat of the brake disc.

[0046] Controlled by the electronically controlled valve head 55 and the flow conduit 51, the system is no longer a simple passive circulation system. Instead, it actively adjusts the heat exchange and a small amount of mass exchange between the two coolant chambers based on real-time temperature sensor data. This enables the management of coolant temperature, ensuring that the coolant flowing towards the braking interface is always within the optimal temperature range. Simultaneously, excess heat can be directed to the tail cavity prepared for cleaning, achieving waste heat utilization. The flow conduit 51, combined with the large-area first heat-conducting fins 53 and second heat-conducting fins 54 at both ends, forms a highly efficient heat conduction path. While physically separating the two chambers to maintain different functional requirements, it also provides heat exchange efficiency far exceeding that of a simple partition. Through controllable heat exchange, a portion of the waste heat generated during braking can be transferred via the coolant to the second storage chamber 23 near the detergent mixing mechanism 24, providing a stable low-temperature heat source for the subsequent preheating of the chemical cleaning agent.

[0047] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, a guide ring groove 2410 is formed on the side wall of the inner cavity of the annular cavity shell 241 near the circular opening, and an embedded circular ring frame 246 is movably installed through the guide ring groove 2410. A buckle 247 corresponding to the guide ring groove 2410 is fixedly installed on the inner ring edge of the embedded circular ring frame 246. A circular guide rail 244 is fixedly installed on the side wall of the inner cavity of the annular cavity shell 241 away from the circular opening, and a fixed ring guide rail 244 is fixed on the outer edge of the embedded circular ring frame 246. A second friction groove rail 249 is installed. A first friction groove rail 245, which is opposite to the second friction groove rail 249, is fixedly installed on the inner ring side of the annular guide rail 244. A storage circulation chamber 242 is fixedly installed at the bottom of the inner cavity of the annular cavity shell 241. An extended hose 243 is fixedly installed on the storage circulation chamber 242. The extended hose 243 is concave into an annular shape and is wrapped between the first friction groove rail 245 and the second friction groove rail 249.

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, a magnetic ring 248 is fixedly installed on the inner ring edge of the embedded ring frame 246. The outer surface of the linkage direct drive module 4 is configured with a metal coating corresponding to the magnetic ring 248. A first delivery hose 2412 is inserted into the bottom of the storage circulation chamber 242, and the first delivery hose 2412 is connected to a fourth delivery hose 34 extending into the second storage chamber 23. A commutation pump 8 is fixedly installed in the middle of the heat dissipation baffle 6. Several external nozzles 9 are fixedly installed on the output end of the commutation pump 8. A third delivery hose 12 is fixedly installed on the side wall of the annular cavity shell 241. The third delivery hose 12 is connected to the input end of the commutation pump 8 through the interior of the cavity shell 21. Several atomizing spray nozzles 2411 are configured on the side of the storage circulation chamber 242, and a second delivery hose 2413 extending out of the second storage chamber 23 is also configured on the side of the storage circulation chamber 242.

[0049] The detergent mixing mechanism 24 is assembled inside the second storage cavity 23 close to the outer surface of the linkage direct drive module 4. Its main function is to integrate a closed cavity system that can utilize the heat and mechanical energy generated during the driving process to automatically complete the preheating and mixing of chemical cleaning agents online, so as to achieve timed or on-demand removal of the salt-etched hard shell on the surface of the brake disc.

[0050] Specifically, an annular guide groove 2410 is formed on the side wall of the annular cavity shell 241 near the circular opening. An embedded annular frame 246 is movably installed through this guide groove 2410. A buckle 247 that slides with the guide groove 2410 is fixedly installed on the inner ring edge of the embedded annular frame 246, allowing it to rotate along the annular path defined by the guide groove 2410. To facilitate the introduction of power and heat, a magnetic ring 248 is fixedly installed on the inner ring edge of the embedded annular frame 246. This magnetic ring 248 is magnetically coupled to the corresponding metal coating on the outer surface of the linkage direct drive module 4. Thus, when the linkage direct drive module 4 rotates due to braking, the embedded annular frame 246 can be driven to rotate through magnetic attraction. A circular guide rail 244 is fixedly installed on the side wall of the inner cavity of the annular cavity shell 241 away from the circular opening. A first friction groove rail 245 is fixedly installed on the inner ring edge of the circular guide rail 244. At the same time, a second friction groove rail 249, which is directly opposite to the first friction groove rail 245, is fixedly installed on the outer edge of the embedded circular frame 246. When the embedded circular frame 246 is driven to rotate by magnetic force, the second friction groove rail 249 and the fixed first friction groove rail 245 generate continuous and opposite relative motion and friction. This friction process directly converts mechanical energy into heat energy. A storage circulation chamber 242 is fixedly installed at the bottom of the inner cavity of the annular cavity shell 241 for storing special chemical cleaning agents. An extended hose 243 is fixedly connected to the storage circulation chamber 242. The extended hose 243 is concave into a circular shape and tightly wraps around the gap between the first friction groove rail 245 and the second friction groove rail 249, thereby efficiently absorbing the heat generated by the friction pair.

[0051] The preheated cleaning agent is mixed with the warm coolant from the cooling system that is fed into the storage circulation chamber 242 through the first delivery hose 2412. The first delivery hose 2412 is connected to the fourth delivery hose 34 that extends into the second storage chamber 23, realizing the connection and heat exchange between the cooling circuit and the cleaning circuit. The warm active cleaning fluid formed by the mixture is then led out through the third delivery hose 12 fixed to the side wall of the annular cavity shell 241. The third delivery hose 12 passes through the cavity shell 21 and is connected to the input end of the commutation pump 8 installed inside the heat dissipation baffle 6. The commutation pump 8 is started under the command of the control system, pressurizes the cleaning fluid and sprays it directionally onto the surface of the vehicle brake disc through several external nozzles 9 fixed on its output end to perform online chemical cleaning.

[0052] In addition, several atomizing spray heads 2411 arranged on the side of the reservoir circulation chamber 242 can be used to assist mixing within the chamber, while the second delivery hose 2413, located on the side of the reservoir circulation chamber 242 and extending into the second reservoir chamber 23, is used for draining waste liquid and replenishing cleaning reagent. The cleaning reagent stored in the reservoir circulation chamber 242 of the cleaning agent mixing mechanism 24 is a weakly acidic solution in the prior art. Its chemical properties enable it to effectively soften, decompose, and peel off the chloride sintered layer that cannot be removed by pure water. During the preheating process, the heat generated by the thermal effect from the drive mechanism 3 and the friction pair raises the temperature of the cleaning agent, which greatly increases its chemical reaction rate. This allows it to assist the cooling water in dissolving scale during vehicle operation intervals. At the same time, preheating reduces the viscosity of the reagent and enhances its ability to penetrate into the micro-crevices of the hard shell. When the warm cleaning liquid is sprayed onto the still warm brake disc surface, the thermal shock and synergistic effect further promote the peeling off of the scale layer and avoid damage to the disc that may be caused by thermal shock.

[0053] The usage method provided by this invention is as follows: When this invention is in use, firstly, when the vehicle needs to perform parking brake, the control system starts the main drive motor 35 in the drive mechanism 3. The output end of the main drive motor 35 directly drives the linkage direct drive module 4. The linkage direct drive module 4 converts the rotational motion into linear thrust, pushing the second friction plate 11 on its output end to move towards the first friction plate 10 fixed on the surface of the heat dissipation plate 6, until the first friction plate 10 and the second friction plate 11 are in close contact, clamping the vehicle brake disc and completing the parking brake.

[0054] During braking, a large amount of heat generated by friction is transferred to the heat dissipation baffle 6 and exchanges heat with the cooling system through the internal interactive side grooves 7. Then, while the main drive motor 35 drives the braking action, its tail end output end transmits power to the cooling cavity 32 through the meshing linkage track 36. The linkage track 36 drives the first circular ring toothed ring 37 at the tail end of the cooling cavity 32 to rotate. The first circular ring toothed ring 37 drives the second circular ring toothed ring 381 meshing with its inner ring tooth to rotate. The coolant conduit 382 and the magnetically attracted coolant arc-shaped cavity 383 fixed on the second circular ring toothed ring 381 revolve accordingly. The magnetically attracted coolant arc-shaped cavity 383 couples the frame-shaped conductor 334 on the inner wall of the semi-circular annular storage bottle 331 through magnetic attraction, driving the frame-shaped conductor 334 to move along the toothed arc edge 333 and drive the bevel gear 336, track sleeve 337 and first heat dissipation fan rod 338 to rotate, stirring the coolant in the semi-circular annular storage bottle 331.

[0055] Meanwhile, the servo motor 384 located in the inner ring of the second annular toothed ring 381 can be started independently, driving the second cooling fan rod 385 to rotate to enhance the airflow in the cooling cavity 32. The low-temperature coolant is pumped from the first cavity of the semi-circular annular storage bottle 331 into the interactive side groove 7 of the heat dissipation baffle 6 through the fourth delivery hose 34. After absorbing the braking heat, the heated coolant flows back to the last cavity of the semi-circular annular storage bottle 331 through another fourth delivery hose 34, and can partially flow into the second storage cavity 23. The heat exchange mechanism 5 located on the partition plate 332 adjusts the exchange of coolant in the flow pipe 51 according to the temperature difference between the two cavities through the electronically controlled valve head 55, equalizes the temperature, and provides a preheating source for cleaning.

[0056] Then, when the system performs online cleaning according to a preset cycle, the detergent mixing mechanism 24 starts working, and the special chemical cleaning agent stored in the storage circulation chamber 242 flows through the extended hose 243 wrapped between the first friction groove rail 245 and the second friction groove rail 249. At this time, the linkage direct drive module 4, which is kept hot due to continuous braking operation, is magnetically coupled to the magnetic ring 248 on the embedded ring frame 246 through the metal coating on its outer surface, driving the embedded ring frame 246 and the second friction groove rail 249 on it to rotate, so that it generates frictional heat with the fixed first friction groove rail 245. This heat is efficiently absorbed by the tightly contacted extended hose 243, thereby preheating the cleaning agent in the hose. Meanwhile, the coolant returning from the cooling system and carrying waste heat is input into the bottom of the storage circulation chamber 242 through the first delivery hose 2412, where it is mixed with the preheated cleaning agent. The resulting warm and active cleaning solution is drawn into the third delivery hose 12 by the drive pump 8 and pressurized and delivered to the external nozzle 9.

[0057] Finally, the pressurized warm cleaning fluid is sprayed from the external nozzle 9 onto the surface of the vehicle's brake disc. For the dense salt-corroded hard shell formed by the sintering of sea salt and de-icing agent chloride at high temperature, this warm chemical cleaning fluid can significantly improve the chemical reaction rate and penetration ability, effectively softening and dissolving the hard shell.

[0058] The dissolved contaminants flow away with the liquid. After the cleaning process is completed, the drive pump 8 stops working, the system is reset, and all mechanisms return to standby status, avoiding the need for manual shutdown intervention required in traditional methods.
