Description

Technical Field

[0001] The invention relates to the technical field of vehicle braking, in particular to an action control device and a control system for a brake piston of a vehicle brake. Background Art

[0002] The rotating element in the brake friction pair is a metal disc that works on the end surface, called a brake disc. When the brake pad moves toward the direction close to the brake disc and presses against the brake disc, braking force is generated. In order to enable the brake pad to move, a brake piston is usually provided in the brake caliper body of the brake. The brake piston can move under the hydraulic action of the brake fluid and push the brake pad to move.

[0003] However, in the related technology, after the brake caliper has been working for a period of time, the reaction force of the brake disc may cause the piston cylinder and the piston rod to deform, resulting in the displacement of the movement direction of the brake piston and brake oil leakage. In addition, the brake oil will absorb moisture in the air, and the brake hydraulic system must allow the brake oil to communicate with the atmosphere to operate normally, which will result in poor braking effect and braking delay, affecting vehicle safety.

Compared with the prior art, the present invention has the following beneficial effects: 1. In the present application, the load-bearing plate blocks the contact position between the piston cylinder and the piston rod, and a pair of retractable elastic pipes are fixedly connected between the load-bearing plate and one end of the piston cylinder to seal the gap between the piston cylinder and the piston rod, thereby preventing oil from leaking through the gap between the piston rod and the piston cylinder, and preventing the piston rod from being worn and deformed under the action of friction iron, causing rapid leakage of oil, thereby ensuring the stability of the brake disc braking.

[0015] 2. In the present application, the electric push rod pushes the arc plate 2 to move toward the top of the waste water tank through the connecting block. Finally, the arc plate 2 covers the top of the waste water tank to seal the waste water tank. When the solenoid valve is opened, the water inside the waste water tank is discharged through the three-way valve and the waste pipe 1 fixedly connected to the normally open end of the three-way valve, thereby precipitating and discharging the water in the brake oil, completing the brake oil purification work, extending the service life of the brake oil, and quickly discharging the water. Without affecting the use status of the vehicle, the insensitivity of the brake caused by the increase of water in the brake oil is reduced, thereby ensuring the stability of the friction iron control drive.

[0016] 3. The pneumatic cylinder working in this application drives the piston plate fixed at the piston end to move. The negative pressure suction generated by the movement of the piston plate acts on the brake oil inside the oil chamber through the guide pipe 1, the three-way valve, the solenoid valve 1 and the waste water tank. The brake oil inside the oil chamber is sucked into the separation box. The vacuum pump draws air from one side of the piston plate through the solenoid valve 2 and the junction box 1, and the air on the top of the brake oil is extracted, thereby reducing the air pressure in the space where the brake oil is located and reducing the temperature required for water evaporation and precipitation. The electric heater is inserted into the installation slot 1 opened at the bottom of the separation box. At this time, the electric heater fixedly installed in the separation box The brake oil is heated to evaporate the water in the brake oil and move to the top of the inner cavity of the separation box, so that the water in the brake oil is separated. The vacuum pump and the solenoid valve work again, and the vacuum pump extracts the water vapor floating on the top of the brake oil to complete the brake oil repair work. After the inside of the separation box is purified, the brake oil is reset to the oil cavity, which effectively extends the service life of the brake oil and can quickly restore the brake oil in a short time, reducing the occurrence of vehicle brake oil emulsification in unexpected situations that affects the use of the vehicle, providing time for users to replace the brake oil and reducing accidents.

[0017] 4. In the present application, the brake oil inside the separation box is heated in a near-vacuum environment, and the separated water vapor can also be extracted by the vacuum pump through the guide pipe piece 5, the solenoid valve 2 and the mounting ring, and then transported to the guide pipe piece 4 through the guide pipe piece 2 and the mounting ring. The water vapor is discharged from the interior of the mounting ring through the guide pipe piece 4, so that the separation component can be installed on the outside of the brake caliper body or inside the brake caliper body according to the specific use scenario of the action control device composed of the brake caliper body, two friction irons, two action control components, the oil inlet pipe and other structures, so as to meet the use needs of different vehicles and ensure the practicality of the action control device.

The brake simulation module compares and calculates the expected brake data with the brake data to calculate the actual brake delay data. The actual brake delay data is fed back to the vehicle system by the data feedback module as a reference for repairing the vehicle. The mode selection module electrically connected to the oil judgment module selects the control mode according to the analysis result of the oil judgment module. The control system controls the electric push rod, solenoid valve and other structures to purify the brake oil, or the control system controls the solenoid valve, separation component, three-way valve and other structures to repair the brake oil, so as to effectively process the brake oil and reduce accidents.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example: Figure 1-Figure 15As shown, the present invention provides a technical solution for an action control device and a control system for a brake piston of a vehicle brake, comprising a brake caliper body 1, a connecting bridge portion 2, a brake disc 3 and an oil inlet pipe 13, friction irons 4 are arranged on both sides of the brake disc 3, and an action control component is arranged between the two friction irons 4 and the brake caliper body 1, an oil chamber 12 and a confluence groove 14 are formed on the brake caliper body 1, a waste water tank 21 is arranged at the bottom of the confluence groove 14, a solenoid valve 1 22 is fixedly connected to the bottom of the waste water tank 21, a three-way valve 23 is fixedly connected to the solenoid valve 1 22, a separation component is connected to the normally closed end of the three-way valve 23, a camera 15 and an arc plate 2 17 are arranged on both sides of the top of the waste water tank 21, an electric push rod 18 is arranged on one side of the arc plate 17, a mounting groove 2 38 is formed on the brake caliper body 1, a supplementary component is arranged inside the mounting groove 38, and the mounting groove 2 38 is used to install the separation component.

[0023] Specifically, one end of the connecting bridge 2 is rotatably connected to the brake disc 3, and the other end of the connecting bridge 2 is fixedly connected to the brake caliper body 1. The connecting bridge 2 plays the effect of fixing the relative position between the brake disc 3 and the brake caliper body 1. The brake disc 3 is partially arranged inside the brake caliper body 1, and friction irons 4 are arranged on both sides of the brake disc 3. An action control component is arranged between the friction iron 4 and the brake caliper body 1. When the brake disc 3 needs to be braked, brake oil is added to the oil chamber 12 through an oil inlet pipe 13 installed on the side of the brake caliper body 1 away from the connecting bridge 2, so that the hydraulic pressure inside the oil chamber 12 is increased, and the piston cylinder 6 in the action control component is fixedly connected to the brake caliper body 1, and a piston rod 8 is inserted into the piston cylinder 6 (a sealing ring is arranged between the piston cylinder 6 and the piston rod 8 to prevent oil leakage, which is a common technical means for hydraulic cylinders), one end of the piston rod 8 is fixedly connected to the friction iron 4, and the other end of the piston rod 8 is fixedly connected to a load-bearing plate 9, such as Figure 2 As shown, the bearing plate 9 is arranged inside the oil chamber 12, so as the hydraulic pressure inside the oil chamber 12 increases, the bearing plate 9 is pushed by the hydraulic pressure, so that the bearing plate 9 pushes the friction iron 4 to approach the brake disc 3 through the piston rod 8, and finally the friction iron 4 fits with the brake disc 3 to brake the brake disc 3; An outer cylinder 7 is fixedly sleeved on the outside of the piston cylinder 6, and the outer cylinder 7 is arranged inside the oil chamber 12. The outer wall of the load-bearing plate 9 contacts the inner wall of the outer cylinder 7. The load-bearing plate 9 blocks the contact position between the piston cylinder 6 and the piston rod 8, and a retractable elastic pipe fitting 11 is fixedly connected between the load-bearing plate 9 and one end of the piston cylinder 6 to seal the gap between the piston cylinder 6 and the piston rod 8 to prevent oil from leaking through the gap between the piston rod 8 and the piston cylinder 6, and to prevent the piston rod 8 from being worn and deformed under the action of the friction iron 4, resulting in rapid leakage of oil, thereby ensuring the stability of the brake disc 3.

[0024] A plurality of springs 10 are arranged on the outside of an elastic tube 11 fixedly connected to the piston cylinder 6, one end of the plurality of springs 10 is fixedly connected to the piston cylinder 6, and the other end of the spring 10 is fixedly connected to the load-bearing plate 9. The elastically retractable springs 10 apply a restoring force to the load-bearing plate 9, so that the load-bearing plate 9 quickly drives the fixed piston rod 8 and the friction iron 4 fixed to the piston rod 8 to reset.

[0025] In addition, the confluence groove 14 formed on the brake caliper body 1 is arranged at the bottom of the oil chamber 12, and the specific gravity of water is greater than that of brake oil, so the water in the brake oil inside the oil chamber 12 will naturally settle into the bottom of the confluence groove 14, and the bottom end of the waste water tank 21 connected to the bottom of the confluence groove 14 penetrates the brake caliper body 1 and extends to the bottom of the brake caliper body 1, and the water is collected in the waste water tank 21. After the vehicle is stopped for more than 6 hours and then started again, the camera 15 arranged on one side of the confluence groove 14 works, and the waste water tank 21 is arranged at the bottom of the shooting path of the camera 15. The camera 15 shoots images and transmits them to the electrically connected control system 5, and the control system 5 analyzes the images. Whether there is water and the distance between the water level and the wastewater tank 21, when the water level reaches the preset range inside the control system 5, the control system 5 controls the electrically connected electric push rod 18 to work, and a connecting block 19 is fixedly connected between the piston end of the electric push rod 18 fixedly connected to the brake caliper body 1 and the arc plate 2 17, and the working electric push rod 18 pushes the arc plate 2 17 to move toward the top of the wastewater tank 21 through the connecting block 19, and finally the arc plate 2 17 covers the top of the wastewater tank 21, so that the wastewater tank 21 is sealed, so that the inside of the wastewater tank 21 is isolated from the oil chamber 12, and the end of the arc plate 2 17 close to the camera 15 is fixedly connected to a rubber pad 20, such as Figure 5 As shown, the arc plate 16 disposed on one side of the rubber pad 20 is fixedly connected to the brake caliper body 1. When the arc plate 27 blocks the top of the waste water tank 21, the rubber pad 20 contacts the camera 15 and the rubber pad 20 deforms to seal the gap between the connecting block 19 and the brake caliper body 1, so that the waste water tank 21 is completely sealed to prevent oil from entering the waste water tank 21. Subsequently, the control system 5 controls the electrically connected solenoid valve 22 to open, and the water inside the waste water tank 21 is discharged through the three-way valve 23 and the waste pipe 24 fixedly connected to the normally open end of the three-way valve 23, thereby precipitating and discharging the moisture in the brake oil, completing the brake oil purification work, extending the service life of the brake oil, and quickly discharging the water. Without affecting the vehicle's use status, the occurrence of brake insensitivity caused by the increase in brake oil moisture is reduced, thereby ensuring the stability of the friction iron 4 control drive.

[0026] When the control system 5 analyzes the brake oil emulsification degree from the captured image and finds that the emulsification degree of the brake oil reaches above the preset value, the control system 5 controls the electrically connected solenoid valve 22 and the three-way valve 23 to work. At this time, the normally closed end of the three-way valve 23 is opened, and the pneumatic cylinder 37 in the separation component is controlled to work. A guide pipe 25 is fixedly connected between one end of the separation box 26 and the normally closed end of the three-way valve 23. Figure 7 As shown, at this time, the separation box 26 is connected to the inside of the oil chamber 12 through the guide pipe 25, the three-way valve 23, the solenoid valve 22 and the waste water tank 21, and the working pneumatic cylinder 37 drives the piston plate 30 fixed at the piston end to move. After the movement of the piston plate 30 generates negative pressure suction, it acts on the brake oil in the oil chamber 12 through the guide pipe 25, the three-way valve 23, the solenoid valve 22 and the waste water tank 21, and the brake oil in the oil chamber 12 is sucked into the separation box 26; the pneumatic cylinder 37 stops working after working for a period of time, and then the solenoid valve 22 stops working and closes, and then the pneumatic cylinder 37 works here for a period of time, so that the piston plate 30 The movement increases the brake oil storage space, so that there is a certain distance between the brake oil and the top wall of the inner cavity of the separation box 26, and one end of the junction box 1 32 is set at a position close to the top wall of the inner cavity of the separation box 26; then the control system 5 controls the electrically connected solenoid valve 2 33 and the vacuum pump 34 to work, because the junction box 1 32 is inserted into the installation groove 5 31 opened on the top of one side of the piston plate 30, the junction box 1 32 fixedly installed on the piston plate 30 is fixedly connected to the solenoid valve 2 33 that is opened for work, and the air inlet end of the vacuum pump 34 is connected to the solenoid valve 2 33, so the vacuum pump 34 passes through the solenoid valve 2 33 and the junction box 1 32 from the piston plate 30 to the The air on the top of the brake oil is extracted by side suction, the air pressure in the space where the brake oil is located is reduced, and the temperature required for water evaporation and precipitation is reduced. After the vacuum pump 34 has worked for a period of time, the vacuum pump 34 and the solenoid valve 2 33 stop working; then the control system 5 controls the operation of the electrically connected electric heater 29. Since the electric heater 29 is inserted into the installation slot 1 28 opened at the bottom of the separation box 26, the electric heater 29 fixedly installed in the separation box 26 heats the brake oil inside the separation box 26 at this time, so that the water in the brake oil evaporates and moves to the top of the inner cavity of the separation box 26, so that the water in the brake oil is separated. After a period of time, the electric heater 29 stops working. The vacuum pump 34 and the solenoid valve 2 33 work again, and the vacuum pump 34 extracts the water vapor floating on the top of the brake oil to complete the brake oil repair work. Finally, the solenoid valve 2 33 and the vacuum pump 34 stop working, the solenoid valve 1 22 works to open, and the pneumatic cylinder 37 works to push the piston plate 30 to reset, so that the brake oil inside the separation box 26 is reset to the oil chamber 12 after being purified, effectively extending the service life of the brake oil, and being able to quickly restore the brake oil in a short time, reducing the occurrence of vehicle brake oil emulsification in unexpected situations that affects the use of the vehicle, providing time for users to replace the brake oil, and reducing the occurrence of accidents.

[0027] A retractable guide pipe 2 35 is fixedly connected to the output end of the vacuum pump 34. The guide pipe 2 35 will not affect the movement of the piston plate 30 and the vacuum pump 34 fixed by the piston plate 30. One end of the guide pipe 2 35 passes through the separation box 26 and is fixedly connected to a mounting ring 36. The mounting ring 36 fixes one end of the guide pipe 2 35 to the outside of the separation box 26, so that the guide pipe 2 35 discharges the exhaust gas from the output end of the vacuum pump 34 out of the separation box 26. The separation box 26 plays a sealing role between the guide pipe 2 35 and the separation box 26. When the space provided by the vehicle is small or the braking power required by the vehicle is small, a mounting groove 28 is formed on the brake caliper body 1, and the separation box 26 can be installed inside the mounting groove 28. Two mounting grooves 31 are formed on the brake caliper body 1 for installing two electric heaters 29. The guide pipe 25 between the three-way valve 23 and the separation box 26 is replaced with a guide pipe 39, so that the brake oil in the oil chamber 12 and the separation box 26 can be kept connected. At this time, after the mounting groove 5 31 is blocked by the sealing plate 42, when the separation box 26 is installed in the mounting groove 2 38, a mounting groove 45 is formed on the top of one side of the piston plate 30, and a junction box 2 44 is installed inside the mounting groove 45. At this time, the junction box 2 44 faces the top wall of the inner cavity of the separation box 26, and the junction box 2 44 is fixedly connected to the solenoid valve 2 33. A guide pipe is fixedly installed between the solenoid valve 2 33 and the air inlet end of the vacuum pump 34. Flow pipe fitting five 43, guide pipe fitting four 40 is fixedly installed between the mounting ring 36 and the brake caliper body 1. At this time, the vacuum pump 34 works to extract the gas at the top of the inner cavity of the separation box 26 through the guide pipe fitting five 43, the solenoid valve two 33 and the junction box two 44, so that the brake oil inside the separation box 26 is in a near-vacuum environment and is heated. The separated water vapor can also be extracted by the vacuum pump 34 through the guide pipe fitting five 43, the solenoid valve two 33 and the mounting ring 36, and then transported to the guide pipe fitting four 40 through the guide pipe fitting two 35 and the mounting ring 36. The water vapor is discharged from the inside of the mounting ring 36 through the guide pipe fitting four 40, so that the separation component can be installed on the outside of the brake caliper body 1 or inside the brake caliper body 1 according to the specific use scenario of the action control device composed of the brake caliper body 1, two friction irons 4, two action control components, the oil inlet pipe 13 and other structures, so as to meet the use needs of different vehicles and ensure the practicality of the action control device.

[0028] In addition, the hydraulic sensor module 501 in the control system 5 monitors the hydraulic values ​​inside the brake master cylinder and the oil chamber 12. The pressure value obtained by the hydraulic sensor module 501 is transmitted to the electrically connected brake simulation module 502. The brake simulation module 502 simulates the expected braking data according to the pressure value and the power conversion ratio parameter of the action control component. The data feedback module 507 obtains the braking data detected in real time in the vehicle system. The braking data is transmitted to the electrically connected brake simulation module 502 by the data feedback module 507. The brake simulation module 502 compares and calculates the expected braking data with the braking data to calculate the actual braking delay data. The actual braking delay data is fed back to the vehicle system by the data feedback module 507 as a reference for repairing the vehicle.

[0029] The image captured by the camera 15 is received and edited by the data feedback module 507 and then transmitted to the oil judgment module 504. The model trained in advance in the oil judgment module 504 analyzes the image to analyze whether there is a water-oil separation layer and the water level, and analyzes the emulsification degree and water content of the brake oil. The mode selection module 505 electrically connected to the oil judgment module 504 selects a control mode according to the analysis result of the oil judgment module 504. When the water level reaches a preset value, the mode 1 instruction in the mode selection module 505 is sent out through the instruction sending module 506 electrically connected to the mode selection module 505. At this time, the control system 5 controls the electric push rod 18, the solenoid valve 1 22 and other structures to work and perform brake oil purification. When the water content or emulsification degree of the brake oil reaches a preset value, the mode 2 instruction in the mode selection module 505 is sent out through the instruction sending module 506. At this time, the control system 5 controls the solenoid valve 1 22, the separation component, the three-way valve 23 and other structures to work and perform brake oil repair work, effectively treat the brake oil and reduce accidents.
