Description

Altitude valve
Technical field
The present invention relates to the vehicle suspension system, particularly a kind of altitude valve of band pneumatic spring (air bag).
Background technique
In prior art, due to the change of vehicle body height in AIRMATIC Dual Control, drive altitude valve adjustable connecting-rod to move up and down, adjustable link position change promotes altitude valve spool controlling rod and rotates, and realizes pneumatic spring air inlet, the function of protecting gas and exhaust.Due to the accuracy of manufacturing of bodywork parts and the impact of suspension welding precision, after causing the installation of conventional height valve, there is certain difference in real balance position and the Theoretical Equilibrium height of pneumatic spring, if difference is too large, can produce harmful effect to the attitude of vehicle body and stability.At this moment the adjustable connecting-rod of Manual height valve is needed to make vehicle body reach balance to compensate foozle.Professional workforce needs time and human cost when adjusting every chassis according to actual conditions.
Summary of the invention
The present invention is a kind of altitude valve, in the vehicle suspension system with pneumatic spring (air bag).Changed by dynamic sensing height of car, complete air inlet in time, protect the action of gas and exhaust, to regulate the height of pneumatic spring (air bag).And vertical mounting type, control pneumatic spring (air bag) air inlet by straight reciprocating motion, protect gas and exhaust.Change conventional height valve and rotated the mode of structure controlling pneumatic spring (air bag) air inlet, protect gas and exhaust by controlling rod.Eliminate after altitude valve is installed needs professional workforce to the adjustment process of height regulating rod simultaneously.
formation of the present invention: a kind of altitude valve, become by upper coupling head, valve body, seal ring, dust ring, spool, lower link head group, be it is characterized in that: upper coupling head is connected with valve body by the screw connection of lower end, and fix with nut screwing clamping, seal ring and dust ring valve body be equipped with, spool is loaded on the bottom of valve body, there is pneumatic spring intake and exhaust channel the inside of spool, and second line of a couplet joint is equipped with in spool bottom.
Valve body air chamber upper end has valve body air inlet of air chamber and valve body external air source to be connected; Spool one end, with spool suction port, is connected with the pneumatic spring intake and exhaust channel in the middle part of spool, and pneumatic spring intake and exhaust channel upper valve core body has spool perforate.
Upper coupling head and the second line of a couplet jiont treatment hanger part fixing torsion sleeve containing flexible material respectively.
According to variable height, by the straight line motion of spool in valve body, control the opening and closing of intake and exhaust channel, realize the control to pneumatic spring breathing action.
Compared with the prior art: when the height of suspension system changes, by the linear reciprocating motion of spool in valve body, when in valve core movement to valve body air chamber, pneumatic spring is communicated with inlet air source by altitude valve, realizes air inlet; When valve core movement is to meta, pneumatic spring gas circuit neither air inlet is not vented yet and is in state of equilibrium; When the vent in spool moves to valve body outside, pneumatic spring gas circuit is exhausted by spool.Change prior art by control valve rod execute transfer realize pneumatic spring air inlet, protect gas and degassing function.

Embodiment
As shown in Figure 1, a kind of altitude valve, become by upper coupling head, valve body, seal ring, dust ring, spool, lower link head group, be it is characterized in that: upper coupling head 1 is connected with valve body 2 by the connecting screw rod 10 of lower end, and tighten fixing with nut 9, seal ring 3 and dust ring 4 valve body 2 be equipped with, spool 5 is loaded on the bottom of valve body 2, and there is pneumatic spring intake and exhaust channel 13 inside of spool 5, and second line of a couplet joint 6 is equipped with in spool 5 bottom.Valve body air chamber 11 upper end has valve body air inlet of air chamber 7 and valve body 2 external air source to be connected; Spool 5 one end, with spool suction port 8, is connected with the pneumatic spring intake and exhaust channel 13 in the middle part of spool 5, and pneumatic spring intake and exhaust channel 13 upper valve core body has spool perforate 12.The hanger part fixing torsion sleeve containing flexible material respectively installed by upper coupling head 1 and second line of a couplet joint 6.
According to variable height, by the straight line motion of spool 5 in valve body 2, control the opening and closing of intake and exhaust channel 13, realize the control to pneumatic spring breathing action.
Valve body part is with sealing configuration, and when ensureing that spool is in meta, pneumatic spring is in equilibrium position, neither air inlet, is not also vented.There is suction port valve body air chamber upper end, be connected with external air source, when ensureing valve core movement to epicoele, namely when the height of pneumatic spring is lower than design height, give pneumatic spring tonifying Qi in time, increase pneumatic spring air pressure inside, the load carrying capacity of pneumatic spring is increased, and then makes pneumatic spring again revert to equilibrium position (design height).When spool decrease beyond equilibrium position (design height), namely when pneumatic spring is increased beyond equilibrium position (design height), pressure release will be carried out to pneumatic spring by the hole of spool, reduce the load carrying capacity of pneumatic spring, and then make pneumatic spring again revert to equilibrium position (design height).Dust ring is equipped with valve body also, for wiping the foreign material that spool may be stained with off.
Spool part one end is with suction port, and for being connected with the inlet and outlet hole of pneumatic spring, middle part is hollow allows gas circulate and in upper position perforate.Realize spool when diverse location, pneumatic spring is inflated, and protects the function such as gas and exhaust.
The hanger part fixing torsion sleeve containing flexible material is respectively installed, is convenient to installation fixing, altitude valve can be made to have when suspension system produces skew simultaneously and automatically regulate compensate function, the working life of prolongation altitude valve.
