Abstract
An air spring in an automobile suspension system is of key importance for improving the smoothness and the comfortableness of a vehicle, protecting roads and cargoes and limiting overload. In a conventional commonly used passive air suspension system, static rigidity of the air spring is irrationally matched with the whole vehicle and cannot be regulated personally, so the vehicle produces a serious sidesway phenomenon during running and passengers and a driver are often dizzy and uncomfortable; therefore, the comfortableness of the passengers and the safety driving of the driver are influenced greatly. The invention discloses a compound air spring so as to solve the problem. Due to the filled liquid in a check valve of the air spring, the static rigidity is regulated, so the static rigidity of the air spring is rationally matched with the whole vehicle; due to the throttling hole in the membrane of the air spring, the dynamic rigidity is regulated; therefore, the dynamic rigidity of the air spring responding to an inertial dynamic load is improved, sidesway of a vehicle body is reduced, and the comfortableness of the vehicle is improved.
Description
One, technical field:
The present invention relates to the pneumatic spring of a kind of vehicle with the passive type air suspension, it regulates quiet rigidity by outside topping up, by built-in membrane air bag is separated into the major-minor air chamber, and its dynamic stiffness is regulated by the fixed orifice on the barrier film.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.It two is exactly: the dynamic stiffness of pneumatic spring can not be followed dynamic load and regulated.
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 do personalized the adjusting to quiet rigidity, and the variation that can follow dynamic load again improves dynamic stiffness automatically, improves the vehicle anti-roll capability, reduces the composite air spring of vehicle side-sway.
Solution of the present invention is: this topping up transfers quiet rigidity and barrier film throttle orifice to transfer the pneumatic spring of rigidity, is combined by air bag 1, upper mounting plate 2, lower installation board 3, gate valve 4, one-way valve 5 and barrier film 6.On the inwall of air bag 1, be provided with barrier film 6, barrier film 6 can be one, also can be several; Barrier film 6 can be made into one with air bag 1, also can separately make, and adopts gluing mode synthetic or hot viscose glue or mechanical connection synthetic again; The mounting point of barrier film 6 and piece number can be decided according to the requirement of different automobile types; On barrier film 6, be provided with throttling pore; The aperture of this throttling pore and quantity can be according to the requirement settings of different automobile types.Gate valve 4 is installed on the lower installation board 3 with one-way valve 5; One-way valve 5 also can be installed on the sidewall of air bag 1 with upper mounting plate 2 on.Quiet rigidity regulating method of the present invention is: charged into through calculating or testing antirust, anti-corrosive and the higher boiling chemical combination liquid of confirming volume by one-way valve 5, just reduced the air volume of equivalent in the air bag 1, improved the quiet rigidity of pneumatic spring; Otherwise, by the chemical combination liquid that gate valve 4 discharge sections have charged into, just increased the air volume of equivalent in the air bag 1, reduced the quiet rigidity of pneumatic spring.
Dynamic stiffness regulating method of the present invention is: because barrier film 6 has been separated into the major-minor air chamber with air bag 1; And on barrier film 6, be provided with throttling pore, when air bag 1 was not compressed, they had been communicated with each sub-air chamber of air bag 1; Volume in the air bag 1 does not have change, and the quiet rigidity of pneumatic spring is constant; And as long as air bag 1 is compressed, just having gas flows between each sub-air chamber of air bag 1, and at this moment, this aperture will produce vapour lock, changes the dynamic stiffness of pneumatic spring, and the dynamic stiffness of pneumatic spring is changed with the speed that air bag 1 moves.Dynamic load is big more, and the speed of air bag 1 motion is just big more, and vapour lock that this aperture produces is just big more, and the dynamic stiffness of pneumatic spring just increases sooner.
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 effectively regulate the quiet dynamic stiffness of pneumatic spring effectively.
Four, description of drawings:
Accompanying drawing 1 is a structure principle chart of the present invention.
Five, embodiment:
Embodiment of the present invention is: quiet rigidity regulating method of the present invention is: charged into through calculating or test antirust, anti-corrosive and the higher boiling chemical combination liquid of confirming volume by one-way valve 5; Just reduce the air volume of equivalent in the air bag 1, improved the quiet rigidity of pneumatic spring; Otherwise, by the chemical combination liquid that gate valve 4 discharge sections have charged into, increased the air volume of equivalent in the air bag 1, reduced the quiet rigidity of pneumatic spring.Dynamic stiffness regulating method of the present invention: because barrier film 6 has been separated into the major-minor air chamber with air bag 1; And on barrier film 6, be provided with throttling pore, when air bag 1 was not compressed, it had been communicated with each sub-air chamber of air bag 1; Volume in the air bag 1 does not have change, and the quiet rigidity of pneumatic spring is constant; And as long as air bag 1 is compressed, just having gas flows between each sub-air chamber of air bag 1, and at this moment, this aperture will produce vapour lock, changes the dynamic stiffness of pneumatic spring, and the dynamic stiffness of pneumatic spring is changed with the speed that air bag 1 moves.Dynamic load is big more, and the speed of air bag 1 motion is just big more, and vapour lock that this aperture produces is just big more, and the dynamic stiffness of pneumatic spring just increases sooner.
