Description

Pneumatic shock absorber control system with electronic damping adjustment function

A shock-absorbing control system, especially a pneumatic shock-absorbing control system with electronic damping adjustment function.

The suspension module is the main structure of the suspension system. The suspension system is used to connect the car body and the wheel. The suspension module is generally composed of elastic elements and shock absorbers. The main function is to properly block the bumps caused by the road surface. For bounce and vibration, the main function of the elastic element is to offset the bouncing of the car body, and the function of the shock absorber is to restore the balance of the elastic element from a large displacement. In order to provide a comfortable ride for the occupants of the vehicle, the damping adjustment of the shock absorber tube controls the speed at which the elastic element restores balance. Among them, the elastic element is the main control element of the distance between the car body and the wheel and the height of the car body. When the elastic element with a longer longitudinal length is selected, the distance between the car body and the wheel will be longer and the height of the car body will be higher. The use of elastic elements with a shorter longitudinal length will make the distance between the car body and the wheel shorter and thus the height of the car body lower.

According to different types of elastic components, shock-absorbing modules can generally be divided into spring-type shock-absorbing modules or pneumatic shock-absorbing modules. The spring-type suspension module uses a mechanical spring as the elastic element, and the rigidity and length of the mechanical spring are fixed. If you want to change the spring rigidity specification or the height of the car body of the vehicle on which the spring-type suspension module is installed, you must Refit by professionals from the car factory, and directly replace the entire set of shock absorber modules on the original vehicle as required. The pneumatic shock absorber module uses the inflated airbag unit as the elastic element. It also includes additional components such as the reservoir bottle, the air motor, and the air valve, which can adjust the volume and internal pressure of the airbag unit, and control the height of the car body and the airbag unit. rigidity.

Existing pneumatic shock absorber control systems are often used in various vehicles (such as modified models). They control the height of the vehicle body and the air pressure value of the airbag unit in the pneumatic shock absorber. It is impossible to directly adjust the shock absorber tube of the shock absorber. Electronic damping adjustment function requires manual adjustment of the soft and hard force value of the shock absorber damping. Therefore, the vehicle driver cannot adjust the damping softness and hardness of the pneumatic shock absorber in real time under different road conditions during driving, so as to adapt to the current road conditions and obtain the best ride feeling.

To sum up, although the existing pneumatic suspension system can adjust the height of the vehicle body through the electronic controller as a switch, the damping of the shock absorber must still be manually adjusted by a person with vehicle expertise, causing the vehicle user The inconvenience. Therefore, the existing pneumatic suspension system still needs to be further improved.

In view of the fact that the damping of the existing pneumatic shock absorber module must be manually adjusted, which causes inconvenience to the vehicle user, the purpose of this model is to provide the vehicle driver with a few seconds for different road conditions at the moment of driving. Inside the car, make appropriate damping soft and hard adjustments to the air shock absorber of the vehicle to provide the best riding feeling under the current road conditions.
