Abstract
The invention relates to an air spring with static stiffness adjusted by filler and dynamic stiffness adjusted by a diaphragm throttling hole. The air spring is of the utmost importance to enhance the smoothness and the comfort of a vehicle, protect roads and freight and limit overfreight. In the commonly-used passive type air suspension system nowadays, as the match between the static stiffness of the air spring and a whole vehicle is not reasonable and cannot be individually adjusted, the phenomenon of lateral motion in the operation of the vehicle is severe, passengers and drivers often feel dizzy and uncomfortable, and the comfort of the passengers and the safely driving for the drivers are seriously affected. Aiming at the difficulty, the invention develops the composite air spring. The static stiffness of the air spring is adjusted through fillers, and the dynamic stiffness of the air spring is adjusted through the throttling hole on the diaphragm of the air spring, so that the dynamic stiffness of the air spring when the air spring is subjected to inertial dynamic loads, the lateral motion of a vehicle body is reduced, and the comfort of the vehicle is enhanced.
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 packing; By barrier film air bag is separated into the major-minor air chamber, 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; Simple and reliable, can carry out personalization to the quiet rigidity of pneumatic spring and regulate; 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 filling 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, packing 4 and barrier film 5.On the inwall of air bag 1, be provided with barrier film 5, barrier film 5 can be one, also can be several; Barrier film 5 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 5 and piece number can be decided according to the requirement of different automobile types; On barrier film 5, be provided with throttling pore; The aperture of this throttling pore and quantity can be according to the requirement settings of different automobile types.Quiet rigidity regulating method of the present invention is: before lower installation board 3 assemblings of air bag 1, insert prior packing 4 through calculating or the definite volume of experiment, packing 4 can be the bulk granular thing, the flowable mass that block and viscosity are very big; The existence of air bag 1 inner stuffing 4 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, in air bag 1, take out the packing 4 that part has dropped into, just quite increased the equivalent volume that holds gas in the air bag 1; 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.Dynamic stiffness regulating method of the present invention is: because barrier film 5 has been separated into the major-minor air chamber with air bag 1; And on barrier film 5, 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: before lower installation board 3 assemblings of air bag 1, insert prior through calculating or test the packing 4 of confirming volume; The existence of air bag 1 inner stuffing 4 has reduced the equivalent volume that holds gas in the air bag 1, thereby has heightened the quiet rigidity of pneumatic spring.Otherwise, in air bag 1, take out the packing 4 that part has dropped into, just quite increased the equivalent volume that holds gas in the air bag 1; Thereby turned down the quiet rigidity of pneumatic spring, satisfied the rational Match of vehicle the quiet rigidity of pneumatic spring.Dynamic stiffness regulating method of the present invention: because barrier film 5 has been separated into the major-minor air chamber with air bag 1; And on barrier film 5, 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.
