Description

Technical Field

[0001] The present invention relates to the technical field of light commercial vehicles, and in particular to a modular linkage mechanism of an electronic booster assembly and a braking system. Background Art

[0002] With the development of the global economy, the market demand for efficient and versatile transportation is increasing. Light commercial vehicles, capable of carrying both passengers and cargo, with excellent fuel efficiency and flexibility, have found widespread application in urban logistics, business travel, and tourist passenger transport. From their initial simple mechanical structure to today's advanced powertrains, intelligent driver assistance systems, comfortable interiors, and user-friendly designs, each generation of products strives to achieve the perfect combination of quality and performance.

[0003] The modular linkage mechanism between the electronic booster assembly and the braking system is centered around the electronic booster assembly and ESC. When the brake pedal is activated, the electronic booster amplifies the applied force, which is then transmitted through the brake lines. The ESC precisely controls the pressure to the caliper to achieve braking. Some existing steering knuckles in light passenger vehicle braking systems are designed too thinly to save weight or money, making them susceptible to deformation and breakage in extreme situations (such as high-speed potholes and collisions). Other knuckles are designed too thick, resulting in increased weight and cost, and also impacting vehicle lightweighting (especially for new energy light passenger vehicles, where weight reduction is crucial for range).

[0004] For this, a solution is needed. Summary of the Invention

[0020] (3) Beneficial effects

[0021] The present invention provides a modular linkage mechanism between an electronic booster assembly and a brake system.

[0022] Beneficial effects:

[0023] 1. Balanced structural strength and lightweight: The main frame, bottom frame, and other components are formed in one piece. Compared to existing split structures, this reduces strength loss at the connection points and improves overall rigidity, effectively avoiding deformation and fracture issues often associated with thin structures and insufficient strength redundancy. Furthermore, by strategically placing weight-reducing slots, weight is reduced while maintaining strength. This addresses the drawbacks of existing technologies, which often result in heavy weight and high costs due to thick designs, and meets the lightweighting needs of new energy vehicles to improve range.

[0024] 2. Adaptability and Maintenance Ease: The four suspension connectors are of varying heights and sizes, and the diagonal design allows for flexible adaptation to different suspension configurations. This improves module versatility and reduces the cost of redesigns for vehicle adaptation compared to existing technologies, which suffer from poor compatibility. The integrated molding and rational structural layout ensure precise component positioning during later maintenance, and the use of process holes (such as locating holes) further enhances maintenance ease.

[0025] 3. System integration and stability: The electronic booster assembly, ESC, brake lines, etc. form a modular linkage mechanism. The steering knuckle, as a key component, works more closely with the various components of the braking system. Compared with the existing technology where the components are scattered and have poor coordination, it can improve the braking response speed and stability. When encountering extreme situations (such as high-speed pits), it relies on a more reasonable structure to reduce the risk of loss of control (modular linkage). The reasonable layout and fixation of ball studs, sensor harnesses and various fixings (ball stud fixings, frame fixings, etc.) ensure stable signal transmission and reliable component connection, avoid system failures caused by loose connections in the existing technology, and improve the overall reliability of the braking system (sensing and fixing optimization).

[0034] The bottom frame 53 has a U-shaped structure, with the lower half wider than the upper half. The top frame 57 has an arcuate structure. The extension frame 58 has an arcuate structure, with the top of the extension frame 58 extending vertically to the left. The side frame 511 has an arcuate structure.

The steering knuckle 5, a key component, works more closely with the other components of the braking system. Compared to existing technologies with dispersed components and poor coordination, this mechanism improves braking response speed and stability. In extreme situations (such as high-speed potholes), the more rational structure reduces the risk of loss of control (modular linkage).

[0043] Analysis of the above content: The reasonable layout and fixation of the ball stud 514, the sensor harness 515 and various fixing parts (ball stud fixing part 516, the frame fixing part 517, etc.) ensure the stability of signal transmission and the reliability of component connection, avoid system failures caused by loose connections in the existing technology, and improve the overall reliability of the braking system (sensing and fixing optimization).

[0044] The system principle, linkage operation and advancement of this solution are further explained.

[0045] 1. System composition and component functions

[0046] Electronic booster assembly: receives the mechanical force input from the brake pedal, amplifies the force through the electronic control unit, and provides a power source for the braking system.

[0047] Brake caliper and brake disc: The brake caliper clamps the brake disc to generate friction, thereby braking the wheel. It is the component that directly performs the braking function.

[0048] Signal transmission and control components

[0049] ESC (Electronic Stability Control System): Installed at the bottom of the electronic booster assembly, it receives the booster output pressure signal through the CAN bus, accurately regulates the braking pressure of each wheel, and prevents the vehicle from slipping or losing control.

[0050] Sensor harness: arranged in the ball stud and limit seat of the steering knuckle, transmits signals such as wheel speed and provides data support for control units such as ESC.

[0051] Mechanical connections and support components

[0052] Steering knuckle: As a key mechanical hub, it connects the brake disc, suspension system and electronic booster assembly. The main frame, bottom frame and other components are molded in one piece, and a balance between strength and lightweight is achieved through the optimization of weight-reducing grooves.

[0053] Brake line: connects the electronic booster assembly, ESC and brake caliper to form a hydraulic transmission path, transmitting the pressure amplified by the booster to the brake caliper.

[0054] Input and support components

[0055] Brake pedal: The driver-operated input component located at the rear end of the electric booster assembly that triggers the braking action.

[0056] Wheel bearing: installed in the center of the brake disc, supports the rotation of the wheel, and cooperates with the steering knuckle to achieve wheel steering.

[0057] System process operation

[0058] Vertical hierarchy: brake pedal → electronic booster assembly → ESC → brake line → brake caliper → brake disc → wheel bearing, forming a vertical control chain from input to execution.

[0059] Lateral linkage: The left and right steering knuckles are respectively connected to the brake discs and suspension connectors on the corresponding sides, and the coordinated regulation of the left and right wheel brake pressure is achieved through the electronic booster assembly and ESC.

[0060] Modular integration: The electronic booster assembly and ESC form the core control module, and the steering knuckle serves as a mechanical module, achieving mechatronic linkage through brake lines and sensor wiring harnesses.

[0061] 2. Working principle of linkage mechanism

[0062] Mechanical linkage process

[0063] Braking triggering stage: The driver steps on the brake pedal, and the mechanical force is transmitted to the rear end of the electronic booster assembly, triggering the motor or hydraulic mechanism inside the booster to work.

[0064] Power amplification stage: The electronic booster assembly amplifies the input force of the brake pedal, converts it into high-pressure oil or mechanical thrust through hydraulic or electric means, and transmits it to the ESC through the brake pipe.

[0065] Pressure regulation stage: ESC accurately adjusts the pressure distribution of each brake line according to the vehicle's driving status (such as wheel speed, steering angle and other sensor signals) to avoid locking of a single wheel.

[0066] Braking execution phase: The regulated pressure is transmitted to the brake caliper through the brake line. The brake caliper clamps the brake disc, generating friction to slow down the wheel. At the same time, the steering knuckle bears the braking reaction force through the suspension connection to ensure stable wheel positioning.

[0067] Signal coordination mechanism

[0068] Sensing signal chain: speed sensor at the wheel bearing → sensor harness → ESC → electronic booster assembly, forming a closed-loop feedback to monitor the braking status in real time.

[0069] Electronic control logic: After receiving the sensor signal, ESC sends adjustment instructions to the electronic booster through the CAN bus, dynamically adjusts the power assist force, and achieves a precise match of "brake pedal travel-power assist output-wheel braking force".

[0070] Mechanical Process

[0071] Vertical force flow: vehicle body weight → suspension connection (steering knuckle) → wheel bearing → brake disc → brake caliper friction, ensuring the stability of the vehicle body posture during braking.

[0072] Lateral force flow: steering knuckle main frame → bottom frame / top frame → suspension connector → suspension system, which disperses the lateral impact force during braking and avoids deformation of the steering knuckle.

[0073] 3. The advanced nature of the linkage system

[0074] Mainly for structural design innovation and performance improvement

[0075]

[0076]

These components are all universal standard components or components known to those skilled in the art. Their structures and principles are known to those skilled in the art through technical manuals or conventional experimental methods. The problem that the present invention solves is that some steering knuckles in existing light passenger vehicle braking systems are designed to be too "thin" in order to reduce weight or save money. They are prone to deformation and fracture when encountering extreme situations (such as high-speed pits and collisions); some steering knuckles are designed to be too "thick", which are heavy and costly, and also affect the lightweighting of the vehicle (especially new energy vehicles, where weight reduction is very important for endurance). While ensuring a balance between structural strength and lightweight, the present invention effectively solves the problems of easy deformation and fracture of steering knuckles, weight redundancy, and insufficient system coordination in the prior art, and to a certain extent improves the system adaptability, coordination, and reliability.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
