Description
Technical field
The present invention relates to vehicle vibration damping technical fields, and in particular to a kind of airsuspension system and oil liquid connecting pipeline and oil
The control method of liquid connecting pipeline.
Background technique
With economic development and technological progress, people have higher requirement to car comfort.Air suspension is interconnected to make
Automobile is effectively improved in uneven road surface by the gas chamber of piping connection difference air spring for a kind of new construction air suspension
Comfort when driving.Existing air suspension interconnection is to be directly connected to the gas chamber of different springs by pipeline, equilibrium air
The pressure of spring improves the comfort of automobile.But interconnecting pipes are directly connected to air spring gas chamber, pressure transmission medium air
Compressibility will cause interconnection response sluggishness and under high frequency pumping interconnect effect weakening；In face of different traveling works
Condition, several simple interconnection mode switchings are not enough to adapt to various operating conditions；When turning and starting to walk to accelerate, interconnection will lead to vehicle body
Roll stiffness reduces, and reduces control stability.
In the prior art, by between the interior gas chamber of different springs (outer gas chamber) interconnecting pipes and two interconnecting pipes
It installs solenoid valve on connecting line additional, achievees the purpose that change interconnection effect, but the invention is not noticed and directly passes through air
It is poor that interconnection will lead to interconnection effect under interconnection sluggishness and high frequency road excitation, and interconnects effect adjustable mode and fix.It is existing
Vehicle body displacement is also converted to by the interconnection air suspension that piston displacement pushes oil liquid connection by multi-connecting-rod mechanism in technology, although
Influence of the air to interconnection effect in interconnecting pipes is eliminated, but its structure is complicated, and it is unadjustable to interconnect effect.It is above-mentioned
Mutual contact mode all has special requirement to the structure of air spring, and it is relatively single to interconnect effect, interconnects effect in limit work
Under condition will not self suppression, safety is poor.
Summary of the invention
Given this, the invention proposes the controls of a kind of airsuspension system and oil liquid connecting pipeline and oil liquid connecting pipeline
Method, by the working condition of control oil pump and solenoid valve, charge and discharge oil liquid carries out the electrodeless adjustment of interconnection effect.
A kind of oil liquid connecting pipeline, including oil liquid pipeline, the cavity shell that oil liquid pipeline both ends are respectively communicated with, oil pocket
Shell is sealedly and fixedly connected on air pipe line, and being sealedly and fixedly connected on the air pipe line inside cavity shell has capsule skin, capsule skin
