Description

Technical Field

[0001] The utility model relates to the technical field of vehicle safety, in particular to a dual independent braking system and a vehicle. Background Art

[0002] In the process of learning to drive a car, drivers often make mistakes due to various factors, such as insufficient skills, complex and changeable road conditions, or mental stress. Among them, one of the most common and dangerous problems is forgetting to brake. In an emergency, if the driver fails to brake in time, it may cause a serious traffic accident. Therefore, how to effectively solve this problem and ensure driving safety has always been the focus of attention in the field of car driving training.

[0003] During driving training, the instructor usually sits in the co-pilot seat and is responsible for guiding the driver to perform various operations. When the driver forgets to brake, the instructor will remind him in time, but such reminders often lead to a lag in braking time. Once the best braking opportunity is missed, it may bring great safety risks to the driver and passengers. There are also two brake pumps, such as CN201120887Y.

[0004] Therefore, how to effectively remind and assist the driver to brake without interfering with the driver's normal operation has become an urgent problem to be solved. Utility Model Content

[0005] A technical problem to be solved by the utility model is that the braking of a training vehicle at the co-pilot position is not effective and reliable enough.

[0006] To solve the above technical problems, an embodiment of the present application provides a dual independent braking system and a vehicle. The dual independent braking system is installed on a vehicle. The dual independent braking system includes a first control component, a second control component, at least one two-way one-way valve and a braking component.

[0007] The first control component includes a first brake pedal and a first master brake cylinder connected to each other, and the first brake pedal is arranged in the main driving compartment; the second control component includes a second brake pedal and a second master brake cylinder connected to each other, and the second brake pedal is arranged in the co-driver's compartment.

[0008] The two-way one-way valve includes a first fluid inlet, a second fluid inlet and a fluid outlet, wherein the first fluid inlet is connected to the first brake master cylinder, and the second fluid inlet is connected to the second brake master cylinder; a brake assembly is directly or indirectly connected to the fluid outlet, and the brake assembly is used to brake the vehicle.

[0009] Among them, the first fluid inlet is connected with the fluid outlet to form a first one-way channel, the second fluid inlet is connected with the fluid outlet to form a second one-way channel, the first brake master cylinder controls the brake assembly through the first one-way channel, and the second brake master cylinder controls the brake assembly through the first one-way channel.

[0010] The two-way check valve has a first inlet, a second inlet and an outlet, which are interconnected through a carefully designed channel. The first inlet is directly connected to the first brake master cylinder to ensure that the brake fluid can flow in smoothly; the second inlet is closely connected to the second brake master cylinder, realizing a dual source of braking force.

[0011] The two-way check valve is designed with two one-way channels inside. The first one-way channel is formed between the first fluid inlet and the fluid outlet, which only allows the brake fluid to flow from the first brake master cylinder to the brake assembly, thereby ensuring the driver's direct control of the brake system. Similarly, the second one-way channel is formed between the second fluid inlet and the fluid outlet, ensuring that the second brake master cylinder can independently provide hydraulic power to the brake assembly when needed.

[0012] In some examples, a valve core capable of bidirectional movement is provided between the first liquid inlet and the second liquid inlet; the valve core moves under the pressure difference between the liquid inlets, and the valve core can automatically and selectively close one of the first liquid inlet and the second liquid inlet according to the pressure change, and the other of the first liquid inlet and the second liquid inlet is connected to the liquid outlet. This design ensures that only one of the two liquid inlets can be connected to the liquid outlet at the same time, thereby avoiding the superposition of braking forces.

[0013] In some examples, the dual independent brake system further includes a vacuum pump and a vacuum tank, the vacuum pump being connected to the vacuum tank, and the first brake master cylinder and the second brake master cylinder being connected to the vacuum tank.

[0014] The vacuum pump and vacuum tank are closely connected and work together to complete the function of power-assisted braking. When the driver steps on the brake pedal, the vacuum pump will quickly extract the air in the vacuum tube and the booster pump chamber and discharge it into the atmosphere, so that the vacuum degree of the vacuum tank and the booster chamber quickly reaches -78KPa. This high vacuum state can provide strong assistance for the driver to step on the brake pedal, so that the entire hydraulic system can push the piston of the master brake cylinder under the action of the driver's pedal force, and then the pressure of the entire hydraulic pipeline system reaches 9 MPa, ensuring that the braking effect is rapid and effective.

[0015] In some examples, the first master brake cylinder and the second master brake cylinder are both vacuum hydraulic brake pumps.

[0016] The vacuum hydraulic brake master cylinder combines the characteristics of vacuum booster and hydraulic transmission. During driving, when the driver steps on the brake pedal, this action will be keenly captured by the brake master cylinder. The internal design of the brake master cylinder is sophisticated, which can quickly convert the force applied by the driver on the brake pedal into the pressure of the brake fluid. This process is essentially a transformation and amplification of force, which enables the limited force originally provided by the driver to be converted into efficient power sufficient to drive the entire braking system.

[0017] In some examples, a hydraulic solenoid valve is connected to the fluid outlet, and the hydraulic solenoid valve is connected to the brake assembly. The hydraulic solenoid valve can adjust the brake pressure and prevent the wheels from locking.

[0018] In the brake system of the training car, the outlet is connected to a hydraulic solenoid valve. The hydraulic solenoid valve is closely connected to the brake assembly and is a key component for controlling the braking process. The hydraulic solenoid valve can not only accurately adjust the brake pressure according to the control command, but also effectively prevent the wheels from locking, ensuring the stability and safety of the vehicle during braking.

[0019] As the core component of ABS (anti-lock braking system), the importance of hydraulic solenoid valve is self-evident. When the vehicle brakes, the ABS solenoid valve can monitor the wheel speed and brake pressure in real time. Once it detects that the wheel is about to lock, it will quickly adjust the brake pressure in the pipeline to prevent the wheel from completely locking. This intelligent adjustment mechanism not only ensures the braking effect, but also greatly reduces the safety hazards caused by wheel locking.

[0020] In some examples, two two-way one-way valves are provided, and the two two-way one-way valves are arranged in parallel.

[0021] The function of the two-way check valve is to ensure the one-way flow of brake fluid in the brake system, thereby avoiding the problem of brake failure caused by brake fluid backflow. When two two-way check valves are set in parallel, they can work together to ensure that the brake system can maintain efficient and stable performance under any circumstances.

[0022] In some examples, the brake assembly includes at least two brake cylinders, and the number of the brake cylinders corresponds to the number of wheels of the vehicle.

[0023] The dual independent braking system is mainly composed of at least two brake cylinders, and the number of these brake cylinders corresponds to the number of wheels of the vehicle. When the instructor or student needs to brake, the system will independently control the brake cylinder of each wheel to achieve precise braking effect. This design enables the training vehicle to quickly and reliably slow down or stop in an emergency, greatly improving driving safety.

[0024] In some examples, four brake cylinders are provided, namely, two front axle brake cylinders and two rear axle brake cylinders.

[0025] This dual independent braking system usually includes four brake cylinders, one on the front axle and one on the rear axle of the vehicle. The two front axle brake cylinders are responsible for controlling the braking of the front wheels, while the two rear axle brake cylinders are responsible for controlling the braking of the rear wheels. These four brake cylinders are independent of each other and each has a complete braking function, which can ensure that the vehicle can brake quickly and effectively in an emergency.

[0026] In some examples, the hydraulic solenoid valve is connected to the front axle brake cylinder via a front axle oil distribution pipe, and the hydraulic solenoid valve is connected to the rear axle brake cylinder via a rear axle oil distribution pipe.

[0027] The core of the dual independent brake system lies in its unique hydraulic control mechanism. Specifically, the hydraulic solenoid valve inside the system is closely connected to the front axle brake cylinder and the rear axle brake cylinder through the front axle oil distribution pipe and the rear axle oil distribution pipe respectively. When the instructor or the system detects that the trainee has made an operational error, the hydraulic solenoid valve will respond quickly and achieve independent control of the front axle or rear axle brake cylinder by adjusting the flow of hydraulic oil in the oil pipe.

[0028] In a second aspect, an embodiment of the present application further provides a vehicle comprising a dual independent braking system as described above.

[0029] The vehicle with the above-mentioned dual independent braking system can realize that the front passenger can brake and slow down or stop the vehicle alone. Taking the training vehicle as an example, the vehicle can be braked reliably in the event of a student's operating error.

[0030] Specifically, the first brake assembly includes a first brake pedal arranged in the main driving compartment and a brake assembly connected thereto. The dual independent brake system of the present application is usually used for the main driver of the training vehicle, that is, the coach, who controls the braking or deceleration of the vehicle by stepping on the first brake pedal.

[0031] The second brake assembly is equipped in the co-pilot's cabin and includes a second brake pedal and brake assembly. This system is specially designed for trainees in training cars, allowing them to actually experience and learn braking operations during simulated driving. Even if the trainee makes an operational error, such as accidentally stepping on the accelerator or improperly operating the brake pedal, the instructor can immediately intervene through the first brake assembly to ensure that the vehicle can be safely decelerated or stopped.

[0044] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0045] like Figures 1 to 3 As shown, embodiment 1 shows a dual independent braking system, which can ensure that the training vehicle can still maintain stable braking performance in the event of student operation errors, and allows the coach to perform independent braking, greatly improving the safety of the training vehicle and students.

[0046] In some examples, a dual independent braking system is installed on a vehicle, and the dual independent braking system includes a first control component, a second control component, at least one two-way check valve, and a brake component. When the vehicle is a training vehicle, the dual independent braking system can enable the co-driver to brake and decelerate or stop the vehicle alone, and can reliably brake the vehicle in the event of a trainee's operating error.

[0047] The first control component includes a first brake pedal 100 and a first brake master cylinder 300 connected to each other, and the first brake pedal 100 is arranged in the main driving compartment; the second control component includes a second brake pedal 200 and a second brake master cylinder 400 connected to each other, and the second brake pedal 200 is arranged in the co-driver's compartment.

[0048] The two-way one-way valve 500 includes a first fluid inlet, a second fluid inlet and a fluid outlet. The first fluid inlet is connected to the first brake master cylinder 300, and the second fluid inlet is connected to the second brake master cylinder 400. The brake assembly is directly or indirectly connected to the fluid outlet, and the brake assembly is used to brake the vehicle.

[0049] Among them, the first liquid inlet is connected to the liquid outlet to form a first one-way channel, the second liquid inlet is connected to the liquid outlet to form a second one-way channel, the first brake master cylinder 300 controls the brake assembly through the first one-way channel, and the second brake master cylinder 400 controls the brake assembly through the first one-way channel.

[0050] To further enhance the safety of driving training, especially in training vehicles, the dual independent braking system ensures that the training vehicle can maintain stable braking performance in the event of student operating errors, allowing the instructor to perform independent braking, greatly improving the safety of the training vehicle and students.

[0051] The dual independent braking system is mainly composed of two control components. The first control component consists of the first brake pedal 100 and the first brake master cylinder 300, which are connected by corresponding pipes and transmission mechanisms. The first brake pedal 100 is set in the main driving room, so that the driver can control the brake easily and intuitively. The first brake master cylinder 300 is the core of the braking force and is responsible for converting the driver's pedaling force into brake hydraulic pressure.

[0052] The second control assembly includes a second brake pedal 200 and a second brake master cylinder 400, wherein the second brake pedal 200 is located in the passenger compartment, providing a brake for the passenger or the instructor in an emergency. This design can provide a certain safety guarantee through the passenger or the instructor when the driver is learning to drive, loses consciousness or cannot operate the brake system.

[0053] The two-way check valve 500 has a first liquid inlet, a second liquid inlet and a liquid outlet, which are interconnected through a carefully designed channel. The first liquid inlet is directly connected to the first brake master cylinder 300 to ensure that the brake fluid can flow in smoothly; the second liquid inlet is closely connected to the second brake master cylinder 400, realizing a dual source of braking force.

[0054] Two one-way channels are designed inside the two-way check valve 500. A first one-way channel is formed between the first fluid inlet and the fluid outlet, which only allows the brake fluid to flow from the first brake master cylinder 300 to the brake assembly, thereby ensuring the driver's direct control of the brake system. Similarly, a second one-way channel is formed between the second fluid inlet and the fluid outlet, ensuring that the second brake master cylinder 400 can independently provide hydraulic power to the brake assembly when needed.

[0055] The brake assembly is directly or indirectly connected to the fluid outlet of the two-way one-way valve 500. When the brake fluid flows to the brake assembly through the one-way channel, the braking force can be quickly and effectively transmitted to the wheels to slow down or stop the vehicle.

[0056] It is worth noting that this dual independent braking system is not a simple superposition design. It combines advanced hydraulic technology and a sophisticated control system to ensure even distribution and efficient transmission of braking force.

[0057] In some examples, a valve core capable of bidirectional movement is provided between the first liquid inlet and the second liquid inlet; the valve core moves under the pressure difference between the liquid inlets, and the valve core can automatically and selectively close one of the first liquid inlet and the second liquid inlet according to the pressure change, and the other of the first liquid inlet and the second liquid inlet is connected to the liquid outlet. This design ensures that only one of the two liquid inlets can be connected to the liquid outlet at the same time, thereby avoiding the superposition of braking forces.

[0058] Inside the valve body, a first liquid inlet and a second liquid inlet are provided, and a valve core capable of bidirectional movement is provided between the two liquid inlets. The valve core is the key to the design, and can move flexibly under the pressure difference between the liquid inlets. When the pressure in the system changes, the valve core will automatically and selectively close one of the first liquid inlet or the second liquid inlet according to the change, ensuring that only one of the two liquid inlets can be connected to the liquid outlet at the same time.

[0059] The above arrangement is characterized by its automatic selectivity and sealing performance. Conventional valves often require manual operation or external signals to control the opening and closing of the valves, but in the two-way one-way valve 500, the movement of the valve core is completely driven by the pressure difference between the liquid inlets. This design not only improves the automation of the system, but also reduces errors and failures caused by manual operation.

[0060] In addition, another important advantage of the two-way one-way valve 500 is that it can avoid the superposition of braking forces. In a hydraulic system, if two liquid inlets are connected to the liquid outlet at the same time, the braking forces may be superimposed, causing system overload or damage. In the two-way one-way valve 500, due to the automatic selective closing function of the valve core, it is ensured that only one liquid inlet is connected to the liquid outlet at the same time, thereby avoiding the superposition of braking forces. This not only protects the safe and stable operation of the system, but also extends the service life of the equipment.

[0061] In order to better illustrate the advantages of this arrangement, an example of a practical application can be given. In an automobile braking system, when the driver steps on the brake pedal, the brake fluid enters the brake through the fluid inlet to generate braking force. If the two fluid inlets are connected to the fluid outlet at the same time, the braking force may be superimposed, causing the wheel to lock or the system to be damaged. With the help of the two-way one-way valve of the present application, it can be ensured that only one fluid inlet is connected to the fluid outlet, thereby avoiding the superposition of braking force and ensuring safe braking of the car.

[0062] In terms of brake components, they are installed near the wheels and are key components that convert the pressure of the brake fluid into actual braking force. When the brake pedal is pressed, the master brake cylinder pushes the brake fluid to the brake components, causing friction to slow down or stop the rotation of the wheels. In a dual independent braking system, each brake component is independently connected to the corresponding brake circuit, ensuring that if any circuit fails, the other circuit can still work normally.

[0063] The dual independent braking system provides more reliable safety protection for the training vehicle with its unique design and efficient performance.

[0064] The vacuum hydraulic brake master cylinder combines the characteristics of vacuum booster and hydraulic transmission. During driving, when the driver steps on the brake pedal, this action will be keenly captured by the brake master cylinder. The internal design of the brake master cylinder is sophisticated, which can quickly convert the force applied by the driver on the brake pedal into the pressure of the brake fluid. This process is essentially a transformation and amplification of force, which enables the limited force originally provided by the driver to be converted into efficient power sufficient to drive the entire braking system.

[0065] Pascal's law, also known as Pascal's principle, is a basic principle in fluid mechanics. It states that the pressure of a liquid in a closed container is equal everywhere and can be transmitted evenly in all directions. In the braking system, this principle is perfectly applied. When the master brake cylinder generates hydraulic pressure, this pressure will follow Pascal's law and be transmitted to the brake cylinder of the axle through a complex pipeline system. In this process, the size and stability of the hydraulic pressure are crucial to ensure the braking effect.

[0066] As the hydraulic pressure is transmitted, the piston of the brake cylinder is pushed. The movement of the piston will further squeeze the brake pad, making it closely contact with the wheel, thereby generating friction and achieving vehicle braking. In this process, the close cooperation between the master brake cylinder and the brake cylinder, as well as the high efficiency and stability of hydraulic pressure transmission, together constitute the core part of the automobile braking system.

[0067] The dual independent braking system can also use an electronic control unit (ECU) to monitor and adjust the working status of the master brake cylinder, further improving the reliability and stability of the braking system.

[0068] In some examples, the dual independent brake system further includes a vacuum pump 600 and a vacuum tank 700 , the vacuum pump 600 is connected to the vacuum tank 700 , and the first brake master cylinder 300 and the second brake master cylinder 400 are both connected to the vacuum tank 700 .

[0069] The dual independent braking system is mainly composed of two independent braking circuits, each of which can brake the vehicle independently. When the trainee makes an operating error during driving, such as accidentally stepping on the accelerator or braking in time, the instructor can activate the independent braking system to quickly slow down or stop the vehicle to avoid potential safety hazards.

[0070] In addition to the basic braking function, the dual independent braking system is also equipped with auxiliary equipment such as vacuum pump 600 and vacuum tank 700. The vacuum pump 600 is closely connected with the vacuum tank 700 to work together to complete the function of power-assisted braking. When the driver steps on the brake pedal, the vacuum pump 600 will quickly extract the air in the vacuum tube and the booster pump chamber and discharge it into the atmosphere, so that the vacuum degree of the vacuum tank 700 and the booster chamber quickly reaches -78KPa. This high vacuum state can provide a strong boost for the driver to step on the brake pedal, so that the entire hydraulic system can push the piston of the master brake cylinder under the action of the driver's pedal force, and then the pressure of the entire hydraulic pipeline system reaches 9 MPa, ensuring that the braking effect is rapid and effective.

[0071] The application of this technology not only improves the braking performance of the training vehicle, but also brings many conveniences to driving training. For example, on complex road conditions such as mountain roads and slippery roads, the dual independent braking system can ensure that the vehicle can brake quickly and stably in any situation, providing students with a safer and more reliable driving environment. At the same time, because the system has an independent braking circuit, the instructor can control the vehicle more accurately by controlling a braking circuit separately when necessary, so as to better guide students in driving practice.

[0072] In some examples, first brake master cylinder 300 and second brake master cylinder 400 are both vacuum hydraulic brake pumps.

[0073] The vacuum hydraulic brake master cylinder combines the characteristics of vacuum booster and hydraulic transmission. During driving, when the driver steps on the brake pedal, this action will be keenly captured by the brake master cylinder. The internal design of the brake master cylinder is sophisticated, which can quickly convert the force applied by the driver on the brake pedal into the pressure of the brake fluid. This process is essentially a transformation and amplification of force, which enables the limited force originally provided by the driver to be converted into efficient power sufficient to drive the entire braking system.

[0074] The dual independent braking system also has the advantages of easy maintenance and long service life. Since the two braking systems are relatively independent, it is more convenient to repair and replace, which reduces maintenance costs. At the same time, the stability of the system also ensures its long service life, which can provide long-term safety protection for the training vehicle.

[0075] In some examples, the fluid outlet is connected to a hydraulic solenoid valve 800 , which is connected to a brake assembly. The hydraulic solenoid valve 800 can adjust the brake pressure and prevent the wheels from locking.

[0076] In the field of training vehicles, safety is always the primary consideration. In order to meet this demand, the application of dual independent braking system becomes the key.

[0077] In the brake system of the training vehicle, the fluid outlet is connected to a hydraulic solenoid valve 800. The hydraulic solenoid valve 800 is closely connected to the brake assembly and is a key component for controlling the braking process. The hydraulic solenoid valve 800 can not only accurately adjust the brake pressure according to the control command, but also effectively prevent the wheels from locking, ensuring the stability and safety of the vehicle during braking.

[0078] As the core component of ABS (anti-lock braking system), the importance of hydraulic solenoid valve 800 is self-evident. When the vehicle brakes, the ABS solenoid valve can monitor the wheel speed and brake pressure in real time. Once it detects that the wheel is about to lock, it will quickly adjust the brake pressure in the pipeline to prevent the wheel from completely locking. This intelligent adjustment mechanism not only ensures the braking effect, but also greatly reduces the safety hazards caused by wheel locking.

[0079] In the application scenario of training vehicles, the advantages of the dual independent braking system combined with the ABS solenoid valve are particularly prominent. Since trainees are often prone to operating errors in the early stages of driving, such as accidentally stepping on the accelerator and braking in time, these errors may threaten the safety of vehicles and personnel. The dual independent braking system can respond quickly in these situations, slowing down or stopping the vehicle through independent braking, effectively avoiding potential safety risks.

[0080] In addition, as a type of ABS solenoid valve, the hydraulic solenoid valve 800 has the characteristics of high precision, high reliability and fast response, which enables the training vehicle to maintain stable braking performance when facing various complex road conditions and emergencies. This not only improves the safety of the training vehicle, but also reduces the cost of vehicle maintenance and repair.

[0081] In some examples, two two-way one-way valves 500 are provided, and the two two-way one-way valves 500 are arranged in parallel.

[0082] Taking a training vehicle as an example, when designing a training vehicle, a solution of setting two two-way one-way valves 500 in parallel can be selected. The function of the two-way one-way valve 500 is to ensure the one-way flow of brake fluid in the brake system, thereby avoiding the problem of brake failure caused by the backflow of brake fluid. When the two two-way one-way valves 500 are set in parallel, they can work together to ensure that the brake system can maintain efficient and stable performance under any circumstances.

[0083] The dual independent braking system greatly improves the braking performance of the training vehicle. Even if one braking system fails, the other braking system can still work normally, ensuring that the vehicle can be safely decelerated or stopped. This is especially important for novice drivers because they may not be able to react quickly and accurately in an emergency.

[0084] The parallel arrangement of the two-way check valve 500 further enhances the reliability of the braking system. As the two valves work together, the flow of brake fluid in the system is smoother, thereby improving the braking response speed and braking efficiency. This can not only reduce the braking distance, but also provide more reaction time for the driver in an emergency.

[0085] The dual independent braking system is sufficiently effective in practical applications. According to a research report on training vehicle accidents, the accident rate of training vehicles with dual independent braking systems when students make operating errors is significantly lower than that of traditional training vehicles. This data fully demonstrates the important role of dual independent braking systems in improving the safety of training vehicles.

[0086] In short, as an important safety configuration of the training vehicle, the dual independent braking system fully demonstrates the advancement and practicality of modern automobile technology in its design concept and practical application. By setting two two-way check valves 500 in parallel, this system can not only improve braking performance and reliability, but also effectively reduce the risk of accidents in practical applications.

[0087] The two-way check valve 500 is a key technology in modern automobile braking systems and an indispensable core component for realizing dual independent braking systems. The setting of this valve body not only ensures the safety of the vehicle during driving, but also provides great convenience for driving training and coaching guidance.

[0088] In practical applications, the role of the two-way check valve 500 is particularly prominent. Taking the driving training scenario as an example, when the trainee in the main driving seat steps on the brake pedal, the hydraulic pressure will quickly enter the valve body from the connecting port between the first brake master cylinder 300 and the two-way check valve 500. Under the action of the hydraulic pressure, the piston in the two-way check valve 500 will move quickly, tightly sealing the connecting port between the second brake master cylinder 400 and the two-way check valve 500, forming an independent brake system circuit. At this time, the trainee's braking operation only affects the brake system in which he is located, and will not interfere with the coach or other parts of the vehicle.

[0089] When the coach in the passenger seat needs to intervene in the braking operation, the situation is different. When the coach steps on the brake pedal, the hydraulic pressure enters the valve body from the connecting port between the second brake master cylinder 400 and the two-way one-way valve 500. Similarly, under the action of the hydraulic pressure, the piston in the two-way one-way valve 500 will move quickly, blocking the connecting port between the first brake master cylinder 300 and the two-way one-way valve 500, forming an independent braking circuit. At this time, the coach's braking operation only affects the brake system where the coach is located, and will not affect the student's operation.

[0090] It is worth noting that the design of the two-way check valve 500 cleverly avoids the superposition of braking forces when the trainee and the instructor step on the brake pedal at the same time. Since the piston in the two-way check valve 500 maintains its position after the previous operation, it moves according to the pressure difference of the oil inlet. This design ensures that only one master brake cylinder can control the service brake system at the same time, thereby avoiding unnecessary superposition of braking forces and the risk of vehicle loss of control.

[0091] The dual independent braking system using the two-way check valve 500 is used in various types of driving training vehicles. This system not only improves the safety of driving training, but also provides more teaching options for coaches. In actual applications, many coaches said that the introduction of the two-way check valve 500 made them more comfortable when guiding students to drive, and they could better control the vehicle dynamics and student operations.

[0092] In some examples, the brake assembly includes at least two brake cylinders, and the number of brake cylinders corresponds to the same number of wheels of the vehicle.

[0093] The dual independent braking system is mainly composed of at least two brake cylinders, and the number of these brake cylinders corresponds to the number of wheels of the vehicle. When the instructor or student needs to brake, the system will independently control the brake cylinder of each wheel to achieve precise braking effect. This design enables the training vehicle to quickly and reliably slow down or stop in an emergency, greatly improving driving safety.

[0094] During driving training, trainees are often prone to operating errors due to lack of familiarity or nervousness. For example, in an emergency, trainees may mistakenly step on the accelerator instead of the brake. At this time, the dual independent brake system can play a key role. The instructor can quickly step on his own brake pedal and brake the vehicle through the independent brake cylinder to avoid accidents.

[0095] In addition, the dual independent braking system has some other advantages. First, since each wheel has an independent brake cylinder, the system can be intelligently adjusted according to the actual condition of the vehicle to achieve a smoother braking effect. Second, the system can also cooperate with other safety systems such as the vehicle's anti-lock braking system (ABS) to further improve driving safety. Finally, the maintenance cost of the dual independent braking system is also relatively low, because each brake cylinder is independent and can be replaced or repaired separately, reducing the difficulty and cost of maintenance.

[0096] In some examples, four brake cylinders are provided, namely, two front axle brake cylinders 910 and two rear axle brake cylinders 930 .

[0097] This dual independent braking system usually includes four brake cylinders, one on the front axle and one on the rear axle of the vehicle. The two front axle brake cylinders 910 are responsible for controlling the braking of the front wheels, while the two rear axle brake cylinders 930 are responsible for controlling the braking of the rear wheels. These four brake cylinders are independent of each other and each has a complete braking function, which can ensure that the vehicle can brake quickly and effectively in an emergency.

[0098] In actual application, the dual independent braking system has shown its unique advantages. For example, when the trainee drives too fast due to improper operation or accidentally stepping on the accelerator, the instructor can quickly start the brake cylinder of the rear axle to brake the rear wheels, thereby effectively reducing the speed of the vehicle. At the same time, since the brake cylinder of the front axle remains in normal condition, the front wheels can still maintain a certain steering ability, helping the vehicle to safely avoid obstacles or make emergency lane changes.

[0099] In addition, the dual independent braking system also has high reliability and stability. According to relevant statistics, the safety accident rate caused by trainee operation errors in training vehicles equipped with dual independent braking systems is greatly reduced. This is mainly due to the dual independent braking system's ability to provide additional safety protection at critical moments to ensure the safety of the vehicle and trainees.

[0100] The brake cylinder of the axle is the actuator of the service brake system. When the driver steps on the brake pedal, the hydraulic pressure of the pipeline will increase as the driver's pedal force increases, and the hydraulic pressure will transmit the force to the piston of the brake cylinder. The smaller the gap between the brake pad and the brake disc moves, the smaller the brake torque is generated in the opposite direction of the wheel rolling, thereby reducing the speed of the vehicle until the vehicle stops;

[0101] The brake cylinder of the axle is the core executive component of the vehicle braking system. When the driver needs to slow down or stop during driving, the brake cylinder plays a vital role.

[0102] When the driver presses the brake pedal, the hydraulic pressure in the brake line will gradually increase as the pedal force increases. This process of hydraulic pressure increase is the key link in the brake system's response to the driver's intention. The hydraulic pressure is transmitted to the brake cylinder through the pipeline, and then the force is transmitted to the piston of the brake cylinder.

[0103] The piston moves under the action of hydraulic pressure. This process is the result of the precise coordination of the internal mechanical structure of the brake cylinder. The movement of the piston will gradually reduce the distance between the brake pad and the brake disc. As the distance decreases, the friction between the brake pad and the brake disc gradually increases, thereby generating a braking torque in the opposite direction of the wheel's rolling direction. This braking torque will hinder the rotation of the wheel, thereby gradually reducing the speed of the vehicle until the vehicle stops completely.

[0104] In some examples, the hydraulic solenoid valve 800 is in communication with the front axle brake cylinder 910 via a front axle oil distribution pipe 920 , and the hydraulic solenoid valve 800 is in communication with the rear axle brake cylinder 930 via a rear axle oil distribution pipe 940 .

[0105] The core of the dual independent brake system lies in its unique hydraulic control mechanism. Specifically, the hydraulic solenoid valve 800 inside the system is closely connected to the front axle brake cylinder 910 and the rear axle brake cylinder 930 through the front axle oil distribution pipe 920 and the rear axle oil distribution pipe 940 respectively. When the instructor or the system detects that the trainee has made an operational error, the hydraulic solenoid valve 800 will respond quickly and achieve independent control of the front axle or rear axle brake cylinder 930 by adjusting the flow of hydraulic oil in the oil pipe.

[0106] The dual independent braking system can immediately activate the front axle brake cylinder 910 to quickly reduce the vehicle speed through the front wheel brake. At the same time, in order to maintain the stability of the vehicle, the dual independent braking system can selectively activate the rear axle brake cylinder 930 to assist the vehicle with the rear wheel brake. This precise braking control can not only reduce the vehicle speed to a safe range in the shortest time, but also effectively prevent the vehicle from losing control due to emergency braking.

[0107] In a second aspect, an embodiment of the present application further provides a vehicle comprising a dual independent braking system as described above.

[0108] The vehicle with the above-mentioned dual independent braking system can realize that the front passenger can brake and slow down or stop the vehicle alone. Taking the training vehicle as an example, the vehicle can be braked reliably in the event of a student's operating error.

[0109] Specifically, the dual independent braking system is mainly composed of two control components. The first control component is composed of the first brake pedal 100 and the first brake master cylinder 300, and the two are connected by corresponding pipelines and transmission mechanisms. The first brake pedal 100 is arranged in the main driving room, so that the driver can control the brake easily and intuitively. The first brake master cylinder 300 is the core of the braking force and is responsible for converting the driver's pedaling force into brake hydraulic pressure.

[0110] The second control assembly includes a second brake pedal 200 and a second brake master cylinder 400, wherein the second brake pedal 200 is located in the passenger compartment, providing a brake for the passenger or the instructor in an emergency. This design can provide a certain safety guarantee through the passenger or the instructor when the driver is learning to drive, loses consciousness or cannot operate the brake system.

[0111] The two-way check valve 500 has a first liquid inlet, a second liquid inlet and a liquid outlet, which are interconnected through a carefully designed channel. The first liquid inlet is directly connected to the first brake master cylinder 300 to ensure that the brake fluid can flow in smoothly; the second liquid inlet is closely connected to the second brake master cylinder 400, realizing a dual source of braking force.

[0112] Two one-way channels are designed inside the two-way check valve 500. A first one-way channel is formed between the first fluid inlet and the fluid outlet, which only allows the brake fluid to flow from the first brake master cylinder 300 to the brake assembly, thereby ensuring the driver's direct control of the brake system. Similarly, a second one-way channel is formed between the second fluid inlet and the fluid outlet, ensuring that the second brake master cylinder 400 can independently provide hydraulic power to the brake assembly when needed.

[0113] The brake assembly is directly or indirectly connected to the fluid outlet of the two-way one-way valve 500. When the brake fluid flows to the brake assembly through the one-way channel, the braking force can be quickly and effectively transmitted to the wheels to slow down or stop the vehicle.
