Problems solved by technology
For example, Mercedes-Benz uses a vehicle balance module, that is, a heavy object is placed in the center of the vehicle body, and the position of the heavy object is changed to reduce the roll when the vehicle is turning. Although this method is simple and easy to implement, the effect is not ideal.

Embodiment Construction
[0028] Such as figure 1 As shown, the present invention adds an annular hydraulic cylinder 2 on the top of the common shock absorber, and the shock absorber spring 1 is compressed by the hydraulic cylinder 2 to make the shock absorber harden. The left side of the shock absorber in the figure is the state when the hydraulic cylinder is not in motion, and the right is the state when the hydraulic cylinder is fully actuated (extended). It can be seen that after the hydraulic cylinder is actuated, the shock absorber spring is compressed, and its elastic force increases to absorb shock. The device is also hardened accordingly.
[0029] During the driving of the car, the hardness of the corresponding damping spring is adjusted correspondingly through the action stroke range of the steering wheel, brake pedal and accelerator pedal, so as to reduce the turning roll range, improve the driving performance and ride comfort of the vehicle. For example, when the car turns left, increasing...

The invention relates to an automobile shock-stiffness real-time regulating and controlling system and a control method thereof. The system comprises a hydraulic pump, four hydraulic cylinders mounted on the top of the four wheel shock absorbers of an automobile, a hydraulic distribution valve in linkage with the steering linkage of the automobile for controlling all hydraulic cylinders, a hydraulic distribution valve in linkage with a brake pedal for controlling front hydraulic cylinders, and a hydraulic distribution valve in linkage with an accelerator pedal for controlling rear hydraulic cylinders. When the automobile steers and the automobile speed is up to a set value, hydraulic cylinders on the two wheel shock absorbers outside the automobile is controlled to act to enhance the stiffness of outside shock absorbers; when the brake pedal is stamped down, the hydraulic cylinders on the front wheel shock absorbers are controlled to act to enhance the stiffness of front side shock absorbers; and when the accelerator pedal is stamped down, the hydraulic cylinders on the rear wheel shock absorbers are controlled to act to enhance the stiffness of rear side shock absorbers. In the invention, the stiffness of shock absorbers is regulated according to different driving states of the automobile, thus greatly improving the driving performance of the automobile. The invention has simple structure and small power consumption on engines.
Description
technical field [0001] The invention relates to a real-time control system for damping hardness of automobiles, belonging to the technical field of damping. Background technique [0002] The shock absorber of existing automobile is generally made up of spring and hydraulic damping oil cylinder, and the hardness of its shock absorber spring is fixed, generally determined by automobile manufacturer, no longer adjusts after leaving the factory. [0003] The car will roll when turning, and the faster the speed, the more serious the roll will be, and it may even roll over. Likewise, the car "nods" or "heads up" when braking or accelerating. [0004] In order to solve problems such as vehicle turning and rolling at high speeds, many automobile companies have proposed their own solutions. For example, Mercedes-Benz uses a vehicle balance module, that is, a heavy object is placed in the center of the vehicle body, and the position of the heavy object is changed to reduce roll when...
