Abstract
The invention discloses a compound air spring combined by an air bag and internal charging liquid thereof, which comprises an air bag 1, an upper mounting plate 2, a lower mounting plate 3, a gate valve 4 and a one-way valve 5, and is characterized in that the gate valve 4 and the one-way valve 5 are respectively arranged on the lower mounting plate 3. Combination liquid whose volume is determined through calculation or experiment is charged into the air bag 1 through the one-way valve 5, and the existing combination liquid reduces equal volume for holding gas in the air bag 1, thereby increasing static stiffness of an air spring. On the contrary, a part of charged combination liquid is discharged from the air bag 1 through the gate valve 4, which equivalently increases the equal volume for holding air in the air bag 1, thereby achieving the purpose of reducing the static stiffness of the air spring, and meeting reasonable matching of automobiles to the static stiffness of the air spring.
Description
One, technical field:
The present invention relates to a kind of vehicle with the pneumatic spring of passive type air suspension and its quiet rigidity controlling device and method.This pneumatic spring especially is adapted to the carrying big bus, and the city bus big bus also is adapted to shipping truck and rail traffic vehicles, and the passive type airsuspension system and the hydro-pneumatic suspension system of special vehicle.
Two, background technique:
In order to improve ride of vehicle, improve the travelling comfort of taking, alleviate the damage of vehicle to road and goods, developed country has adopted pneumatic spring widely in the suspension system of its carrier vehicle.China recent years is also being widelyd popularize and mandatory employing pneumatic spring.In the pneumatic spring technology of constantly development, in order further to improve the rigidity control characteristic of pneumatic spring, more be applicable to the variation of car load in order to it, people have carried out deep exploration.In the passive type airsuspension system of generally using at present; Because the anti-roll stiffness of pneumatic spring is lower; Caused the vehicle side-sway phenomenon that is in operation more serious, it is dizzy and uncomfortable that occupant and driver are produced, and seriously influences occupant's travelling comfort and driver's safe driving.Cause the one of the main reasons of this phenomenon to be: the quiet rigidity of pneumatic spring can't be regulated with personalized according to the Rational Parameters coupling of car load.
Three, summary of the invention:
The object of the invention will be developed a kind of low cost exactly, and is simple and reliable, can carry out rational Match and personalized the adjusting to the quiet rigidity of the pneumatic spring of passive type suspension system, improves the vehicle anti-roll capability, reduces the composite air spring of vehicle side-sway.
Solution of the present invention is: this composite air spring by air bag and the combination of inner topping up thereof is combined by air bag 1, upper mounting plate 2, lower installation board 3, gate valve 4 and one-way valve 5.The quiet rigidity of pneumatic spring is regulated: in air bag 1, charge into through calculating or testing the chemical combination liquid of confirming volume via one-way valve 5, the existence of chemical combination liquid has reduced the equivalent volume that holds gas in the air bag 1, thereby has heightened the quiet rigidity of pneumatic spring.The raising of the quiet rigidity of pneumatic spring helps reducing the side-sway of vehicle body when advancing, and improves the dynamic stability of vehicle body.Otherwise, from the chemical combination liquid that air bag 1 interior discharge section has charged into, just quite increased the equivalent volume that holds gas in the air bag 1 by gate valve 4; Thereby reached the purpose of turning down the quiet rigidity of pneumatic spring, satisfied the rational Match of vehicle the quiet rigidity of pneumatic spring.
The present invention is simple in structure, and is with low cost, easy for installation, and reliable performance is a kind of combined air air spring that can carry out rational Match and personalized adjusting effectively to the quiet rigidity of pneumatic spring.
Four, description of drawings:
Accompanying drawing 1 is a structure principle chart of the present invention.
Five, embodiment:
Embodiment of the present invention is: in air bag 1, charge into through calculating or testing the chemical combination liquid of confirming volume via one-way valve 5, the existence of chemical combination liquid has reduced the equivalent volume that holds gas in the air bag 1, thereby has heightened the quiet rigidity of pneumatic spring.The raising of the quiet rigidity of pneumatic spring helps reducing the side-sway of vehicle body when advancing, and improves the dynamic stability of vehicle body.Otherwise, from the chemical combination liquid that air bag 1 interior discharge section has charged into, just quite increased the equivalent volume that holds gas in the air bag 1 by gate valve 4; Thereby reached the purpose of turning down the quiet rigidity of pneumatic spring.
