Abstract
The invention discloses a composite air spring formed by combining an airbag with a built-in external adjusting piston, which is specifically formed by combining an airbag 1, an upper mounting plate 2, a lower mounting plate 3, a piston 4, a cylinder barrel 5, an adjusting bolt 6 and a locking nut 7. The composite air spring is structurally characterized in that the cylinder barrel 5 is fixedly arranged on an upper plane of the lower mounting plate 3; the piston 4 is sleeved in the cylinder barrel 5; the adjusting bolt 6 is arranged on the lower mounting plate 3; the upper part of the adjusting bolt 6 is supported against a lower plane of the piston 4; the lower part of the adjusting bolt 6 extends out of a bottom plane of the lower mounting plate 3; and the locking nut 7 is arranged at the lower part of the adjusting bolt 6. The static stiffness of the composite air spring can be adjusted by screwing the adjusting bolt 6 to push the piston 4 to vertically move in the cylinder barrel 5 and adjust the equivalent volume for accommodating gases in the airbag 1, and thereby the aim of adjusting the static stiffness of the air spring is achieved.
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 outside the stiffness characteristics of removing air bag of this phenomenon, main cause is: 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: the composite air spring of this air bag and built-in external regulation type piston in combination is combined by air bag 1, upper mounting plate 2, lower installation board 3, piston 4, cylinder barrel 5, adjusting bolt 6 and locking nut 7.The planar central position installs and fixes cylinder barrel 5 on lower installation board 3; Piston 4 is sleeved in the cylinder barrel 5, regulates bolt 6 and is installed on the central position of lower installation board 3, and its top withstands on the lower plane of piston 4; The lower plane of lower installation board 3 is stretched out in the bottom, and leaves adjustment stroke.Locking nut 7 is installed in the bottom of regulating bolt 6; The rigidity regulating method of this composite air spring is: unclamp locking nut 7; The adjusting of turn to the right bolt 6 will promote piston 4 and in cylinder barrel 5, upwards move; Piston 4 moving up in cylinder barrel 5 just opened up greatly the volume between piston 4 bottom surfaces and cylinder barrel 5 bottoms; It has reduced the equivalent volume that holds gas in the air bag 1, has heightened the quiet rigidity of pneumatic spring.Otherwise; Bolt 6 is regulated in turn left will make adjusting bolt 6 move down; Piston 4 has reduced the volume between piston 4 bottom surfaces and cylinder barrel 5 bottoms because the effect of air bag 1 interior gas pressure moves down thereupon in cylinder barrel 5, 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.
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 in the passive type airsuspension system, 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: the quiet rigidity regulating method of this composite air spring is: unclamp locking nut 7; The adjusting of turn to the right bolt 6 will promote piston 4 and in cylinder barrel 5, upwards move; Piston 4 moving up in cylinder barrel 5 just opened up greatly the volume between piston 4 bottom surfaces and cylinder barrel 5 bottoms; It has reduced the equivalent volume that holds gas in the air bag 1, has heightened the quiet rigidity of pneumatic spring.Otherwise; Bolt 6 is regulated in turn left will make adjusting bolt 6 move down; Piston 4 is owing to the effect of gas pressure in the air bag 1 moves down in cylinder barrel 5 thereupon; Reduced the volume between piston 4 bottom surfaces and cylinder barrel 5 bottoms, increased the equivalent volume that holds gas in the air bag 1, the quiet rigidity of pneumatic spring reduces.
