As shown in Figure 1, the interconnected air spring constructions of transverse direction involved in the present invention is applied to laterally interconnected air suspension, and laterally interconnected two, left and right pneumatic spring is symmetrically arranged.Two air spring constructions symmetries, for the pneumatic spring in left side, its upper cover plate 1-a, interior air chamber interconnected valve 2-a, piston sleeve 4-a, outer air chamber vesicle skin 5-a, interior air chamber vesicle skin 6-a, piston 7-a, lower cover plate 8-a, inflation/deflation valve 9-a and interior air chamber interconnecting pipes 12 are that Chinese Patent Application No. is 201510665774.0, name is called the structure proposed in the document of " the two air chamber pneumatic springs being applicable to longitudinally interconnected air suspension ", and the pneumatic spring lumen segmentation in left side is interior air chamber A1 and outer air chamber B1 by this structure.Similarly, for the pneumatic spring on right side, comprise upper cover plate 1-b, interior air chamber interconnected valve 2-b, piston sleeve 4-b, outer air chamber vesicle skin 5-b, interior air chamber vesicle skin 6-b, piston 7-b, lower cover plate 8-b and inflation/deflation valve 9-b, the pneumatic spring inner chamber on right side is split into interior air chamber A2 and outer air chamber B2.The two ends of interior air chamber interconnecting pipes 12 connect interior air chamber interconnected valve 2-a and the interconnected valve 2-b of interior air chamber respectively, by interconnected for interior air chamber A1 and interior air chamber A2.
For the present invention's laterally interconnected pneumatic spring, need ensure that the volume of the interior air chamber in the inner chamber of same pneumatic spring is less than the volume of outer air chamber, namely, air chamber A1 volume is less than outer air chamber B1 volume, and interior air chamber A2 volume is less than outer air chamber B2 volume.On this basis, the present invention respectively with the addition of the interconnected valve of outer air chamber on outer air chamber B1, B2 of left and right two pneumatic spring, namely the interconnected valve 3-a of outer air chamber being communicated with outer air chamber B1 is set respectively on upper cover plate 1-a, upper cover plate 1-b arranges the interconnected valve 3-b of outer air chamber being communicated with outer air chamber B2, and connect the interconnected valve of two outer air chambers with outer air chamber interconnecting pipes 10, the two ends of outer air chamber interconnecting pipes 10 are connected on outer air chamber interconnected valve 3-a and the interconnected valve 3-b of outer air chamber.Be provided with the interconnected solenoid valve 11 of outer air chamber in the middle of air chamber interconnecting pipes 10 outside, in the middle of interior air chamber interconnecting pipes 12, be provided with the interconnected solenoid valve 13 of interior air chamber.In addition, also an inside and outside interconnecting pipes 14 is connected between air chamber interconnecting pipes 10 and interior air chamber interconnecting pipes 12 outside.Inside and outside interconnected solenoid valve 15 is provided with in the middle of inside and outside interconnecting pipes 14.
For the opening and closing according to the interconnected solenoid valve of driving cycle conservative control, the present invention utilizes acceleration transducer 16 collection vehicle speed information, steering wheel angle sensor 17 is utilized to implement collection vehicle steering wheel angle information, degree of will speed up sensor 16 and steering wheel angle sensor 17 are connected to control system 18 respectively by signaling line, the information collected is supplied to control system 18 in order to judge current driving operating mode, makes control decision.Control system 18 also connects different interconnected solenoid valves by drive circuit 19, and after control decision is determined, control decision is passed to drive circuit 19 with the traveling of control signal by control system 18.Drive circuit 19 connects the coil of the interconnected solenoid valve of outer air chamber 11, the interconnected solenoid valve of interior air chamber 13 and inside and outside interconnected solenoid valve 15 respectively, can control the opening and closing of these three interconnected solenoid valves.
If the interconnected solenoid valve 11 of outer air chamber is opening state, then can there is gas exchanges between air chamber B1, B2 in left and right the outer of two pneumatic springs; If the interconnected solenoid valve 13 of interior air chamber is opening state, then can there is gas exchanges between air chamber A1, A2 in left and right the interior of two pneumatic springs.The air chamber that gas exchanges can occur is and participates in interconnected air chamber, and participate in interconnected gas chamber volume larger, roll stiffness is less.
Inside and outside interconnected solenoid valve 15 just may be opened when only air chamber solenoid valve 11 and interior air chamber solenoid valve 13 are opening state outside, now all can there is gas exchanges in 4 air chambers of left and right pneumatic spring, the air pressure of 4 air chambers can be made to reach unanimity, its role is to: balance each air chamber air pressure, avoid because interior air chamber A1, A2 cannot be communicated with all the time with outer air chamber B1, B2 and cause 2 air chambers draught head constantly to accumulate, affecting pneumatic spring working life.
Roll stiffness is reduced because left and right pneumatic spring is interconnected, lifting vehicle run smoothness, reduce the control stability of tempo turn operating mode, therefore the horizontal interconnected pneumatic spring of the present invention has following demand for control: during 1, parking operating mode, for balancing each air chamber air pressure, 4 air chambers of two pneumatic springs in left and right need be made all interconnected, and UNICOM together; During 2, turning operating mode, for reducing body roll, roll stiffness need be made as far as possible high, reduce body roll, therefore need to make left and right pneumatic spring be in non-interconnected state; 3, during low speed driving operating mode, the interconnected run smoothness advantage brought of pneumatic spring can be made full use of, the whole volume of pneumatic spring need be made to participate in interconnected.During operating mode of 4, driving at moderate speed, the advantage of interconnected pneumatic spring can be utilized more fully, but want appropriateness to prevent turning to suddenly of vehicle, certain roll stiffness need be possessed, pneumatic spring major part volume therefore should be made to participate in interconnected.During operating mode of 5, running at high speed, although this operating mode is straight-line travelling, but on the one hand, generally mean when running at high speed that pavement conditions is excellent, not high to the demand promoting run smoothness further, on the other hand for bringing rollover risk by pneumatic system time lag when pre-anti-vehicle takes a sudden turn suddenly, higher roll stiffness need be ensured, therefore should only make pneumatic spring fraction volume participate in interconnected.According to demand for control, the control of the interconnected pneumatic spring of transverse direction involved in the present invention comprises formulates control strategy stage and actual driving stage, specific as follows:
Formulate the control strategy stage.Determine a steering wheel angle threshold value

Step 4: control system 18 is according to current vehicle speed
v t judge currently whether be in speed operation.
If current vehicle speed
v t <
v 1 , judge currently to be in speed operation, then control system 18 controls drive circuit 19 and opens the interconnected solenoid valve of outer air chamber 11 and the interconnected solenoid valve 13 of interior air chamber, but closes inside and outside interconnected solenoid valve 15, no longer performs lower step 5.Now, the interior air chamber A1 in left side and the interior air chamber A2 on right side is interconnected, and the outer air chamber B1 in left side and the outer air chamber B2 on right side is interconnected, but not interconnected between inside and outside air chamber.If current vehicle speed
v t >
v 1 , then step 5 is performed.
Step 5: control system 18 is according to current vehicle speed
v t judge currently to be in middling speed operating mode or high-speed working condition.
If current vehicle speed
v t >
v 2 judge currently to be in work condition state of running at high speed, then control system 18 controls drive circuit 19 and opens the interconnected solenoid valve 13 of interior air chamber, close the interconnected solenoid valve of outer air chamber 11 and inside and outside interconnected solenoid valve 15, now, the interior air chamber A1 in left side and the interior air chamber A2 on right side is interconnected, and because interior gas chamber volume is less than outer air chamber, therefore it is interconnected to guarantee that pneumatic spring only has fraction volume to participate in; If current vehicle speed
v 1 <
v t <
v 2 then think current and be in the work condition state that drives at moderate speed, then control system 18 controls drive circuit 19 and opens the interconnected solenoid valve 11 of outer air chamber, the interconnected solenoid valve of air chamber 13 and inside and outside interconnected solenoid valve 15 in closing, now, the outer air chamber B1 in left side and the outer air chamber B2 on right side is interconnected, because outer gas chamber volume is greater than interior air chamber, therefore can guarantee that pneumatic spring major part volume participates in interconnected.
