Description

Technical Field

[0001] This invention relates to disc brakes, and more particularly to a disc brake with a self-heating structure. Background Technology

[0002] Disc brakes, as a high-efficiency braking device, are widely used in various equipment requiring high-efficiency braking, such as automobiles, construction machinery, and rail transportation, due to their advantages of smooth braking, rapid response, and stable braking performance. Their performance is directly related to the operational safety and reliability of the equipment.

[0003] Currently, the heat dissipation of existing disc brakes mainly relies on the natural heat dissipation of the brake disc itself and the simple heat dissipation fin structure set on the surface of the brake disc. Its heat dissipation efficiency is low and it cannot quickly dissipate the large amount of heat generated during braking.

[0004] Therefore, in order to address the problems of poor heat dissipation and low heat dissipation efficiency of existing disc brakes, which easily lead to a decrease in braking performance and accelerated component wear, a disc brake with a self-heating structure is to be developed. Summary of the Invention

[0005] The technical solution of the present invention is as follows: a disc brake with a self-heating structure includes a brake disc mounted on a wheel. The brake disc has a hollow interior and a mounting bracket is provided on the brake disc. A fixed shell is fixed on one side of the mounting bracket. Brake pads are symmetrically arranged inside the fixed shell. The front brake pads are slidably connected to the fixed shell. A hydraulic component is provided on the side of the fixed shell and is connected to one of the brake pads. A reservoir is provided inside the mounting bracket. The top of the reservoir is connected to an injection pipe, and the bottom of the reservoir is connected to a first tube. An annular cylinder is connected to the brake disc. The annular cylinder has a hollow interior and multiple equally spaced slots along its circumference. A first annular plate is rotatably connected to the annular cylinder. The first annular plate is fixedly connected to the first tube. A retraction mechanism is provided between the brake disc and the mounting bracket to retract the coolant. A drive mechanism is provided on the mounting bracket to drive the piston rod to move.

[0006] In one embodiment, the retraction mechanism includes a second tube body connected to a liquid storage cylinder. A condenser is provided on the second tube body. A second annular plate is fixedly connected to the side of the second tube body away from the liquid storage cylinder. The second annular plate is rotatably connected to a brake disc. A piston cylinder is provided on the mounting bracket. A third tube body is connected between the bottom of the piston cylinder and the second tube body. A piston rod is slidably connected inside the piston cylinder.

[0007] In one embodiment, the drive mechanism includes a servo motor mounted on a mounting bracket, and the output shaft of the servo motor is fixedly connected to a threaded rod, which is threadedly connected to the upper part of the piston rod.

[0008] In one embodiment, a first check valve is also included, which is disposed on the second pipe body, and a second check valve is disposed on the second pipe body.

[0009] In one embodiment, the device further includes a ring plate, which is fixedly connected to the inside and outside of the brake disc. The ring plate has multiple equally spaced water outlets on its outer side along the circumferential direction. A rotating plug plate is rotatably connected to the side of the ring plate near the water outlets. Multiple first torsion springs are connected between the rotating plug plate and the ring plate.

[0010] In one embodiment, an exhaust pipe is also included, with multiple exhaust pipes fixedly connected at equal intervals inside the brake disc, and the exhaust pipes having multiple heat dissipation holes.

[0011] In one embodiment, a guide frame is also included, which is fixedly connected to the mounting frame. A rotating sleeve is rotatably connected to the inner side of the guide frame, and a fan is provided on the rotating sleeve. A rotating shaft is rotatably connected to one side of the mounting frame, and a belt assembly is connected between the rotating shaft and the fan. A bevel gear set is connected between the rotating shaft and the bottom of the threaded rod.

[0012] In one embodiment, a ball valve is also included, which is rotatably connected to the first tube body. A rotating column is fixedly connected to the side of the ball valve. The rotating column and the first tube body are rotatably connected. A pressing plate is connected to the rotating column. A second torsion spring is connected between the pressing plate and the first tube body. A front brake pad is connected to a push rod, which is pressed and engaged with the pressing plate.

[0013] In one embodiment, a scraper is also included, which is fixedly connected to one side of the mounting bracket and is in close contact with the brake disc.

[0014] In one embodiment, the hydraulic assembly consists of a hydraulic cylinder, a hydraulic piston, and hydraulic oil. The hydraulic cylinder is located at the front of the fixed housing, and the hydraulic piston is slidably connected inside the hydraulic cylinder. The hydraulic piston is connected to the brake pad.

[0015] The beneficial effects of this invention are as follows: 1. This solution combines the self-heating structure of the brake disc with the circulating liquid cooling system. It utilizes the centrifugal force generated by the rotation of the brake disc to intermittently throw out the coolant, which covers the surface of the brake disc in all directions and quickly removes the frictional heat. The heat dissipation and cooling efficiency is high, which can effectively suppress the high-temperature thermal fade of the brake disc and improve braking stability. After the machine stops, the coolant is automatically recovered and recycled through the cooperation of the motor, one-way valve and condensation component, reducing coolant loss.

[0016] 2. This invention relies on centrifugal force to automatically open the water outlet, achieving precise spraying and heat dissipation of coolant. After shutdown, the torsion spring drives the plug plate to reset and seal the water outlet, preventing coolant backflow and accumulation, ensuring smooth recovery of the cooling medium, and improving the stability of circulating heat dissipation.

[0017] 3. The present invention adds heat dissipation holes and links the transmission structure to drive the fan to operate, which can actively send air to the brake to enhance air circulation, assist liquid cooling heat dissipation, quickly dissipate brake heat, and significantly improve the overall heat dissipation efficiency.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] A disc brake with a self-heating structure, such as Figures 1-5As shown, the device includes a brake disc 2, which is mounted on a wheel. The brake disc 2 has a hollow internal structure. A mounting bracket 1 is installed above the brake disc 2. A fixed housing 3 is fixedly connected to the left side of the mounting bracket 1. Brake pads 5 are symmetrically arranged inside the fixed housing 3. The front brake pads 5 are slidably connected to the fixed housing 3. A hydraulic assembly 4 is installed at the front of the fixed housing 3 and is connected to the front brake pads 5. The hydraulic assembly 4 consists of a hydraulic cylinder, a hydraulic piston, and hydraulic oil. The hydraulic cylinder is located at the front of the fixed housing 3, and a hydraulic piston is slidably connected inside the hydraulic cylinder. The rear of the hydraulic piston is connected to the front brake pad 5. The hydraulic cylinder contains hydraulic oil, and the front of the hydraulic cylinder is connected to an external oil supply device. The hydraulic oil is controlled by the external oil supply device to control its flow, thereby driving the brake pad 5 to brake the brake disc 2, thus achieving the purpose of braking the vehicle. A reservoir 6 is located in the upper part of the mounting bracket 1. The top of the reservoir 6 is connected to an injection pipe 7, and the bottom of the reservoir 6 is connected to a first pipe body 8. An annular cylinder 9 is fixedly connected to the middle of the brake disc 2. The annular cylinder 9 has a hollow internal structure, and its front part is open along the circumferential direction. There are multiple equally spaced slots 902. The front of the annular cylinder 9 is rotatably connected to a first annular plate 10. The first annular plate 10 and the first tube body 8 are fixedly connected. A back-pull mechanism for drawing back the coolant is provided between the brake disc 2 and the mounting bracket 1. A drive mechanism for moving the piston rod 14 is provided on the mounting bracket 1. The back-pull mechanism includes a second tube body 11, which is connected to the upper left part of the liquid storage cylinder 6. A condenser 1102 is provided on the second tube body 11, which can cool the coolant in the second tube body 11. The lower part of the second tube 11 is fixedly connected to the second annular plate 1101, and the second annular plate 1101 is rotatably connected to the front of the brake disc 2. The upper left front side of the mounting frame 1 is provided with a piston cylinder 12. The bottom of the piston cylinder 12 is connected to the third tube 13 between the second tube 11 and the piston cylinder 12. The piston rod 14 is slidably connected inside the piston cylinder 12. The drive mechanism includes a servo motor 18, which is located on the left side of the mounting frame 1. The output shaft of the servo motor 18 is fixedly connected to a threaded rod 17, and the threaded rod 17 and the upper part of the piston rod 14 are threadedly connected.

[0028] like Figure 1 and Figure 5 As shown, it also includes a first one-way valve 15, which is disposed on the second pipe body 11 and located below the third pipe body 13. A second one-way valve 16 is disposed on the second pipe body 11 and located above the third pipe body 13. The second one-way valve 16 is located above the first one-way valve 15.

[0029] When using the disc brake with its self-heating structure, the mounting bracket 1 can be installed on the car base first. In order to accelerate the heat dissipation of the brake disc 2, the following scheme is set up: Coolant can be injected into the reservoir 6 through the injection pipe 7. The coolant in the reservoir 6 will then enter the annular cylinder 9 through the first pipe 8. When the brake disc 2 rotates, it will drive the annular cylinder 9 to rotate, which in turn drives the slot 902 to rotate. When the slot 902 is connected to the lower part of the first pipe 8, the coolant will enter the annular cylinder 9 through the first pipe 8. Subsequently, during the rotation of the brake disc 2, the centrifugal force will cause the coolant to be thrown outward, allowing it to be thrown from the center to the inner and outer peripheries of the brake disc 2, thus achieving the purpose of cooling. The intermittent connection between the slot 902 and the lower part of the first pipe 8 allows the coolant to be thrown out intermittently. When the brake stops rotating, the coolant inside the brake will fall to the position of the second pipe 11 due to gravity. After each stop, the servo motor 18 will automatically start once, driving the threaded rod 17 to rotate. The rotation of the threaded rod 17 drives the piston rod 14 to move upward. At the same time, under the action of the second one-way valve 16, the coolant in the reservoir 6 is prevented from being drawn into the piston cylinder 12. The upward movement of the piston rod 14 draws the coolant in the lower part of the brake disc 2 upward. Under the action of the condenser 1102, the coolant flowing through the second pipe 11 is cooled, making it easier to recycle. When the threaded rod 17 rotates and drives the piston rod 14 downward, under the action of the first one-way valve 15, the coolant will flow back into the reservoir 6 through the second one-way valve 16 and the second pipe 11. Under the action of the first one-way valve 15, the coolant is prevented from being pushed back into the brake disc 2.

[0030] like Figure 4 and Figure 6 As shown, it also includes a ring plate 19, which is fixedly connected to the inside and outside of the brake disc 2. The outer side of the ring plate 19 has multiple equally spaced water outlets 20. A rotating blocking plate 21 is rotatably connected to the side of the ring plate 19 near the water outlets 20. The rotating blocking plate 21 is used to block the water outlets 20. Two first torsion springs 22 are connected between the rotating blocking plate 21 and the ring plate 19.

[0031] When the brake disc 2 rotates, the centrifugal force causes the rotating block plate 21 to rotate and swing open, opening the outlet 20. The coolant is then thrown into the external space of the ring plate 19, and the first torsion spring 22 is twisted. When the brake disc 2 stops, under the action of the first torsion spring 22, the rotating block plate 21 rotates back to its original position and blocks the outlet 20. In this way, the coolant is prevented from flowing back into the middle of the brake disc 2. The coolant then flows downward into the second pipe 11 so that the used coolant can be recycled.

[0032] like Figure 4As shown, it also includes an exhaust pipe 24, and multiple exhaust pipes 24 are fixedly connected to the inside of the brake disc 2 at equal intervals. Three heat dissipation holes 23 are opened on both the front and rear sides of the exhaust pipe 24.

[0033] like Figure 1 As shown, it also includes a guide frame 251, which is fixedly connected to the front of the mounting frame 1. A rotating sleeve 252 is rotatably connected to the inner side of the guide frame 251. A fan 25 is provided on the rotating sleeve 252. A rotating shaft 26 is rotatably connected to the lower left of the mounting frame 1. A belt assembly 27 is connected between the rotating shaft 26 and the fan 25. A bevel gear set 28 is connected between the rotating shaft 26 and the bottom of the threaded rod 17.

[0034] To accelerate the heat dissipation of the brake, components such as heat dissipation holes 23 and fan 25 are added. When the threaded rod 17 rotates, it drives the bevel gear set 28 to rotate. The rotation of the bevel gear set 28 drives the rotating shaft 26 to rotate. The rotation of the rotating shaft 26 drives the belt assembly 27 to rotate. The belt assembly 27 drives the fan 25 to rotate. When the fan 25 rotates, it blows air towards the brake, thereby accelerating the heat dissipation of the brake.

[0035] like Figure 1 and Figure 7 As shown, it also includes a ball valve 29, which is rotatably connected inside the first tube body 8. A rotating column 30 is fixedly connected to the side of the ball valve 29. The rotating column 30 and the first tube body 8 are rotatably connected. A pressing plate 31 is fixedly connected to the rotating column 30. A second torsion spring 32 is connected between the pressing plate 31 and the first tube body 8. A push rod 33 is fixedly connected to the front of the brake pad 5 on the front side. The push rod 33 and the pressing plate 31 are in a pressing fit.

[0036] After the brake disc 2 stops, the first tube 8 and the slot 902 may overlap, causing the coolant to continue flowing out. This could result in a large amount of coolant flowing into the lower part of the brake disc 2, making it difficult to cool the brake disc 2 evenly. To address this, the following solution is implemented: When the front brake pad 5 moves backward, it will drive the push rod 33 to move backward. The push rod 33 will then squeeze the squeeze plate 31. The squeeze plate 31 rotates backward, which in turn drives the ball valve 29 to rotate through the rotating column 30. This will close the first tube 8 and prevent the coolant from flowing out. At this time, the second torsion spring 32 is twisted. When the front brake pad 5 moves forward and resets, it drives the push rod 33 to move forward. After the push rod 33 moves forward and separates from the squeeze plate 31, the second torsion spring 32 will drive the squeeze plate 31, the rotating column 30, and the ball valve 29 to rotate, opening the first tube 8.

[0037] like Figure 1 As shown, it also includes a scraper 34, which is fixedly connected to the upper right part of the mounting bracket 1. The scraper 34 is close to the brake disc 2. When the brake disc 2 rotates, the scraper 34 can scrape the dirt off the outer wall of the brake disc 2.

[0038] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
