Abstract
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
The present invention relates to the automobile shock technical field, exactly is a kind of automobile active damper that is applied in the Vehicle damper system.
Background technology
The form of automobile shock has multiple, but the vehicle vibration damping system is passive damping vibration damping method at present, and the road surface seismaesthesia of jolting is strong, ride comfort is poor, present technical study does not produce again technical application, and therefore, it is wide that current shock attenuation unit is tested the update market outlook.
Summary of the invention
In order to subdue as much as possible vibration, improve ride comfort, the vehicle vibration damping method of study, improvement is present is significant.The compatible traditional vibration insulating system of apparatus of the present invention can be eliminated the spike that produces because of Uneven road in the running car and impact, and ride comfort is improved greatly.Simultaneously, if this covering device breaks down, vehicle still can normally move, and just cushioning performance is identical with common vehicle.Main contents of the present invention have: one, vibration insulating system minute two-stage control; Two, first order vibration damping is " real vibration damping ", and main eliminate " reality " impacted, and second stage vibration damping is " empty vibration damping ", and main eliminate " void " is impacted; Three, first and second grade comprehensive intelligent control.Its principle of work is: when automobile normally moved, vehicle body was on the real damper spring 4, if when wheel was subject to less real the impact, impulsive force was sponged by real damper spring 4 and damping hole 5; When if wheel is subject to larger real the impact, this device begins to work, (damping hole 5 is difficult to absorb fast fast larger impact, causing occupant's seismaesthesia strong) check valve 12 opens, by pass valve 11 is opened, make in the real shock absorber oil liquid pressure constant, seamlessly transit impact with the spring force of real damper spring 4, and make and impact the energy that produces and stored by energy storage 10; Continue to increase if impact, then start the real vibration damping of secondary, check valve 17 is opened, and by pass valve 18 is opened, and absorbs the large impact energy, and is stored by energy storage 10.If when wheel was subject to empty impact the (wheel cross after the projection hollow), empty shock absorber 2 pressure reduced rapidly, behind reducing valve 16 settling pressures, reducing valve 16 is opened, and to empty shock absorber 2 makeup energy, alleviates empty shock effect by energy storage 10.By position sensor 13 induction piston positions, make the oil of empty shock absorber 2 also keep the capacity of needs, if too much, and pressure is greater than supply pressure, then duty valve 15 is opened, and unnecessary fluid is discharged.

The specific embodiment
Install one-level hydraulic actuating cylinder active damper additional at original vibration insulating system, offer the buffering test device at original damping system again, realize " real vibration damping " function, eliminating " reality " impacts, simultaneously Information Monitoring feeds back to control system, if tire is in virtual state, then start active damper, eliminate " void " and impact.After using this device, can control the spike that reduces the overwhelming majority and impact, make it within the human comfort tolerance range.One, vibration insulating system divides two-stage control; Two, first order vibration damping is " real vibration damping ", and main eliminate " reality " impacted, and second stage vibration damping is " empty vibration damping ", and main eliminate " void " is impacted; Three, first and second grade comprehensive intelligent control.Its principle of work is: when automobile normally moved, vehicle body was on the real damper spring 4, if when wheel was subject to less real the impact, impulsive force was sponged by real damper spring 4 and damping hole 5; When if wheel is subject to larger real the impact, this device begins to work, (damping hole 5 is difficult to absorb fast fast larger impact, causing occupant's seismaesthesia strong) check valve 12 opens, by pass valve 11 is opened, make in the real shock absorber oil liquid pressure constant, seamlessly transit impact with the spring force of real damper spring 4, and make and impact the energy that produces and stored by energy storage 10; Continue to increase if impact, then start the real vibration damping of secondary, check valve 17 is opened, and by pass valve 18 is opened, and absorbs the large impact energy, and is stored by energy storage 10.If when wheel was subject to empty impact the (wheel cross after the projection hollow), empty shock absorber 2 pressure reduced rapidly, behind reducing valve 16 settling pressures, reducing valve 16 is opened, and to empty shock absorber 2 makeup energy, alleviates empty shock effect by energy storage 10.By position sensor 13 induction piston positions, make the oil of empty shock absorber 2 also keep the capacity of needs, if too much, and pressure is greater than supply pressure, then duty valve 15 is opened, and unnecessary fluid is discharged.
