Embodiment Construction
[0006] On the basis of improving the original damping system, a first-level hydraulic cylinder active damper is installed, and then a buffer test device is installed on the original damping and damping system to realize the "passive damping" function and eliminate "convex" impacts. The collected information is fed back to the control system. If the wheel is in a void state, the active shock absorber is activated to eliminate the impact of gravity. After using this device, most of the peak impacts can be controlled and reduced, making it within the range of human comfort. 1. The vibration reduction system is divided into two levels of control; 2. The first level of vibration reduction is "passive vibration reduction", which mainly eliminates "convex" impacts, and the second level of vibration reduction is "active vibration reduction", which mainly eliminates the wheel void. The impact of gravity; third, first and second level comprehensive intelligent control. Its working prin...

The invention provides an initiative shock reducing device of an automobile. The initiative shock reducing device is compatible with a traditional shock reducing system, can eliminate peak impact caused by uneven road surface when the automobile runs and enable the comfort to be greatly improved in driving. In addition, when the initiative shock reducing device breaks down, the automobile can still run normally, but the shock reducing performance is the same as common vehicles. The initiative shock reducing device is mainly characterized in that the shock reducing system adopts two-stage control; the first-stage shock reduction is 'actual shock reduction' and mainly eliminates 'actual' impact, and the second-stage shock reduction is 'virtual shock reduction' and mainly eliminates 'virtual' impact; and the first-stage shock reduction and the second-stage shock reduction are controlled comprehensively and intelligently. A primary hydraulic cylinder driving shock reducer can be added on the existing shock reducing system, and a buffer testing device is further arranged on an existing damping shock reducing system, so that an 'actual shock reduction' function is achieved, the 'actual' impact is eliminated, simultaneously information is acquired and fed back to a control system, and the driving shock reducer is started and the 'virtual' impact is eliminated if tires are in a virtual state. After the initiative shock reducing device is used, most of peak impact can be controlled and reduced, and the impact is controlled within a comfort range which can be borne by people.
Description
technical field [0001] The invention relates to the technical field of automobile damping, in particular to an active damping device for automobiles applied in a vehicle damping system. Background technique [0002] There are many forms of automobile shock absorption, but the current automobile shock absorption system is passive damping and vibration reduction method, which has a strong shock feeling on bumpy roads and poor ride comfort. There is a broad market prospect for devices to be tested and updated. Contents of the invention [0003] In order to reduce the vibration as much as possible and improve the ride comfort, it is of great significance to study and improve the current automobile vibration reduction methods. The device of the invention is compatible with the traditional damping system, can eliminate the peak impact caused by the uneven road surface during the running of the car, and greatly improves the ride comfort. At the same time, if the set of devices ...
