Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of light passenger vehicles, in particular to a modular linkage mechanism of an electronic power booster assembly and a braking system. BACKGROUND

[0002] With the development of the global economy, the market demand for efficient and multifunctional transportation tools is increasing. Light passenger vehicles can meet the needs of carrying people and have certain cargo carrying capacity, and have good fuel economy and flexibility. They are widely used in urban logistics distribution, business travel, tourism passenger transport and other fields. From the initial simple mechanical structure to today's advanced power system, intelligent driving assistance system, comfortable interior and humanized design, each generation of products strives to achieve the perfect combination of quality and performance.

[0003] The modular linkage mechanism of the electronic power booster assembly and the braking system takes the electronic power booster assembly and the ESC as the core. After the brake pedal is triggered, the electronic power booster amplifies the force, which is transmitted through the brake pipeline, and the ESC precisely controls the pressure to the brake caliper to realize braking. Some steering knuckles in the existing light passenger vehicle braking system are too "thin" in structure design in order to reduce weight or save money, and are prone to deformation and fracture in extreme conditions (such as high-speed over pits, collisions); some steering knuckles are designed too "thick", which is heavy, high in cost, and also affects the lightweight of the vehicle (especially new energy light passenger vehicles, weight reduction is very important for endurance).

[0044] The system principle, linkage operation and advancement of the scheme are further described.

[0045] 1, System composition and component function

[0046] Electronic booster assembly: receiving the mechanical force input by the brake pedal, amplifying the force through the electronic control unit, and providing a power source for the brake system.

[0047] Brake caliper and brake disc: the brake caliper clamps the brake disc to generate friction force, realizes wheel braking, and is a component directly executing the brake function.

[0048] Signal transmission and control component

[0049] ESC (Electronic Stability Control System): installed at the bottom of the electronic booster assembly, receiving the booster output pressure signal through the can bus, accurately controlling the brake pressure of each wheel, and preventing the vehicle from slipping or losing control.

[0050] Sensing wire harness: arranged in the ball pin and the limiting seat of the steering knuckle, transmitting the wheel speed and other signals, and providing data support for the control unit such as ESC.

[0051] Mechanical connection and support component

[0052] Steering knuckle: as a key mechanical hinge, connecting the brake disc, suspension system and electronic booster assembly, the main frame, bottom frame and other components are integrally formed, and the strength and lightweight balance are realized through the optimization of the weight reduction groove.

[0053] Brake pipeline: connecting the electronic booster assembly, ESC and brake caliper, forming a hydraulic transmission path, and transmitting the amplified pressure of the booster to the brake caliper.

[0054] Input and support component

[0055] Brake pedal: Input component operated by the driver, located at the rear end of the electronic booster assembly, triggers braking action.

[0056] Wheel bearing: Installed at the center of the brake disc, supports the rotation of the wheel, and cooperates with the steering knuckle to realize wheel steering.

[0057] System flow operation

[0058] Longitudinal hierarchy: Brake pedal → Electronic booster assembly → ESC → Brake pipeline → Brake caliper → Brake disc → Wheel bearing, forming a vertical control chain from input to execution.

[0059] Lateral association: Left and right steering knuckles are connected to the corresponding side brake discs and suspension connectors, and through the electronic booster assembly and ESC, the braking pressure of the left and right wheels is coordinated and controlled.

[0060] Modular integration: Electronic booster assembly and ESC form the core control module, steering knuckle as mechanical module, through brake pipeline and sensing wire harness to realize electromechanical integrated linkage.

[0061] 2. Working principle of linkage mechanism

[0062] Mechanical linkage process

[0063] Brake 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 pipeline.

[0065] Pressure regulation stage: ESC accurately adjusts the pressure distribution of each brake pipeline according to the vehicle driving state (such as wheel speed, steering angle, etc. Sensing signals) to avoid single wheel lock.

[0066] Brake execution stage: The regulated pressure is transmitted to the brake caliper through the brake pipeline, the brake caliper clamps the brake disc, generates friction to slow down the wheel, and the steering knuckle bears the braking reaction force through the suspension connector to ensure stable wheel positioning.

[0067] Signal coordination mechanism

[0068] Sensing signal chain: Wheel bearing speed sensor → Sensing wire harness → ESC → Electronic booster assembly, forming a closed loop feedback, real-time monitoring of braking state.

[0069] Electronic control logic: after receiving the sensing signal, the ESC sends adjustment instructions to the electronic booster through the CAN bus to dynamically adjust the boosting force, so as to realize accurate matching of "brake pedal stroke-boosting output-wheel braking force".

[0070] Mechanical flow

[0071] Vertical force flow: vehicle body weight-suspension connecting piece-knuckle bearing-brake disc-brake caliper friction, to ensure the stability of the vehicle body posture during braking.

[0072] Lateral force flow: knuckle main frame-bottom frame / top frame-suspension connecting piece-suspension system, to disperse the lateral impact force during braking and avoid deformation of the knuckle.

[0073] 3. Advantages of the linkage system
