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, and its dynamic stiffness is regulated by the fixed orifice on the barrier film; When vehicle is run into the road surface projection under steam, can also reduce its dynamic stiffness automatically, to reduce the impact of projection to vehicle body.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 variation simple and reliable and that can follow dynamic load improves dynamic stiffness automatically, improves the vehicle anti-roll capability, reduces the vehicle side-sway; Can carry out personalization to its quiet rigidity again and regulate, in the time of can also in vehicle driving, running into the road surface projection, reduce its dynamic stiffness automatically, reduce the impact composite air spring of projection vehicle body.
Solution of the present invention is: this packing and membranes pores are regulated the pneumatic spring that quiet dynamic stiffness plus-minus dashes, by air bag 1, upper mounting plate 2, lower installation board 3, packing 4, barrier film 5, subtract towards film piece 6 be connected rivet 7 and combine.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 once-through, also can separately make, and adopts gluing mode synthetic or hot viscose glue synthetic again, also can adopt the mode of mechanical connection synthetic; 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.Subtract towards film piece 6 by having connected rivet 7 connections in the central position of barrier film 5, subtract the throttle orifice that is provided with on the film piece 6, its aperture and quantity are all less than the throttle orifice on the barrier film 5; Connecting rivet 7 also can be screw.Packing 4 is bulk granular material or larger-size block or the bigger flowable mass of viscosity.
Quiet rigidity regulating method of the present invention is: before lower installation board 3 is installed, in air bag 1, put into through calculating or test the packing 4 of confirming volume, packing 4 has occupied the equivalent volumes of pressurized gas in the air bag 1, has heightened the quiet rigidity of pneumatic spring; Otherwise, take out the packing 4 that part has been inserted by lower installation board 3, just increased the equivalent volumes of pressurized gas in the air bag 1, reduced 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 be provided with throttling pore with subtracting on film piece 6 at barrier film 5; When air bag 1 is not compressed; They have been communicated with the major-minor air chamber of air bag 1, and the 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 the major-minor 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.When the vehicle inertia dynamic load that is in operation increases; Will compressing gasbag 1; Promote upper mounting plate 2 and move down, this moment, the gas of barrier film 5 epicoeles can flow downward, and the pressure of epicoele is higher than cavity of resorption; Subtract towards film piece 6 compacted being attached on the barrier film 5, gas can only be through subtracting less orifice flow on the film piece 6 to cavity of resorption; The dynamic stiffness of regulating pneumatic spring by the less vapour lock that the hole produced that subtracts on the film piece 6; 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, is beneficial to the balance dynamic load, reduces the inclination and the side-sway of vehicle.And when running into the road surface projection in the vehicle driving, promptly compressing gasbag 1 promotes to move on the lower installation board 3; At this moment, the pressure of air bag 1 cavity of resorption can be higher than its epicoele, and this pressure can promote to subtract towards film piece 6 and upwarp; And be communicated with the upper and lower cavity of barrier film 5 by the more and bigger hole on the barrier film 5; Make vapour lock drop to minimum, reduce its dynamic stiffness automatically, to reduce the impact of projection vehicle body.
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.
