Embodiment Construction

[0013] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0014] At present, the typical suspension structure is composed of elastic elements, guide mechanisms and shock absorbers. In the automobile suspension system, the barrel type shock absorber is widely used, and it can play the role of vibration reduction in both compression and extension strokes. It is called two-way. Active shock absorber. In the suspension system, vibration is generated due to the impact of the elastic eleme...

Abstract

The invention relates to an intelligent-regulation automobile car damper based on a single chip microcomputer. When a car frame or a car body and a car axle are vibrated to have relative movement, a piston in the damper moves up and down, so that an oil fluid in a damper cavity repeatedly flows into another cavity from one cavity through different pores. Damping force is formed on vibration by virtue of friction between pore walls and the oil fluid and internal friction among oil liquid molecules, so that the car vibration energy is converted into oil fluid heat energy which is adsorbed by the damper and then diffused into atmosphere. According to the intelligent-regulation automobile car damper, by improving the structure of the damper of a current car suspension system, the damper can regulate chassis height according to practical needs of a driver; and meanwhile, oil consumption is not added, the comfort of the original car is kept, and the operation stability and the safety are improved. Bad roads such as an earth road, high and low pits and the like can be leisurely coped, by-pass trouble caused by water ambulation is also avoided, and practical requirements, in a using process, of a car owner can be effectively satisfied.

Description

technical field [0001] The invention relates to an intelligently adjusted automobile shock absorber based on a Freescale chip, belonging to the technical field of electromechanical control. Background technique [0002] At present, there are more and more ordinary family cars, which are mainly consumed in two directions, one is hatchback or sedan, and the other is SUV. Due to the main advantages of good passability and off-road performance, SUVs are currently sought after, but on the other hand, due to their heavy weight and large drag coefficient, the fuel consumption per 100 kilometers is usually more than ten, twenty liters or higher. Generally, the fuel consumption of a car is less than ten liters per 100 kilometers. In today's shortage of oil and energy resources, it is obvious that the cost of using an SUV is much higher than that of a car. At the same time, due to the serious atmospheric smog and stricter regulations on vehicle exhaust emissions, the government is ad...
