Description
Technical field
The present invention relates to a kind of air spring additional air chamber, especially a kind of volume has the adjustable air spring of grade to add gas
Room.
Background technology
Air spring suspension systems are now medium-sized or above car and mostly one of equipment of medium-to-high grade vehicle indispensability at present, no
The riding comfort of occupant can be only improved, can also be played a protective role to road.Wherein air spring is the pass of the system
One of key member to increase the gas gross of air spring, reduces the natural frequency of vibration, it usually needs increase setting auxiliary chamber, with
The vibration characteristics of air spring is influenced, plays the role of attenuation vibration.But it is existing auxiliary chamber volume be usually fix
, once designing, can not just it adjust, application range is relatively narrow, and suitability is poor.
Invention content
In order to solve the above technical problems, the present invention provides a kind of air spring additional air chamber, added by solenoid valve control
The chamber and chamber number that gas chamber is connected with air spring, realize air spring additional air chamber volume has the grade adjustable.
In order to achieve the above objectives, the technical scheme is that：Volume has the adjustable air spring additional air chamber of grade, including
Auxiliary chamber cylinder body and air spring, air spring are connected with connecting tube, auxiliary chamber cylinder body by partition board be divided into volume into than
Small chamber, middle chamber and the big chamber of example variation, between small chamber, the side of middle chamber and big chamber and connecting tube respectively successively
It is connected by the first conduit, the second conduit with third conduit, first is separately installed on the first conduit, the second conduit and third conduit
Solenoid valve, second solenoid valve and third solenoid valve, the first solenoid valve, second solenoid valve and third solenoid valve are driven by driving circuit
Dynamic, driving circuit is controlled by controller.
As the further setting of above-metioned scheme, the volume of middle chamber is 2 times of small chamber, and the volume of big chamber is lumen
2 times of room.
Auxiliary chamber is divided into three different volumes chambers by the present invention, is connected by changing auxiliary chamber with air spring
Chamber and chamber number, realize the mesh for having grade adjustable, changing spring system performance of air spring additional air chamber volume
's.

Dynamic circuit 7 drives, and driving circuit 7 is controlled by controller 8.
The present invention operation principle be：Since auxiliary chamber cylinder body 1 by partition board 4 has been divided into the small of the proportional variation of volume
Chamber 11, middle chamber 12 and big chamber 13, and 2 times that the volume of middle chamber 12 is small chamber 11, during the volume of big chamber 13 is
2 times of chamber 12.In use, controller 8 sends out signal to driving circuit 7, the first solenoid valve 61, are driven by driving circuit 7
Two solenoid valves 62 and third solenoid valve 63 are turned on and off, the first solenoid valve 61, second solenoid valve 62 and third solenoid valve 63
Combined type is opened so that small chamber 11, middle chamber 12 and big chamber 13 are provided with different volume combinations, it is achieved thereby that air
Spring auxiliary chamber volume has the grade adjustable.
