Abstract
The invention discloses a composite air spring formed by combining a built-in spiral spring with filled liquid, which is specifically formed by combining an airbag 1, an upper mounting plate 2, an upper positioning pin 3, a spiral spring 4, a lower positioning pin 5, a gate valve 6, a lower mounting plate 7 and a one-way valve 8. The composite air spring is structurally characterized in that the upper positioning pin 3 and the lower positioning pin 5 are respectively arranged at central positions of inner planes of the upper mounting plate 2 and the lower mounting plate 7; the upper part of the spiral spring 4 is sleeved on the upper positioning pin 3; the lower part of the spiral spring 4 is sleeved on the lower positioning pin 5; the gate valve 6 and the one-way valve 8 are arranged on the lower mounting plate 7; and the free height of the spiral spring 4 is equal to or slightly greater than the net inner hollow height of the airbag 1 at the maximum running speed of a vehicle. The dynamic stiffness of the air spring when a vehicle moves is compensated by the spiral spring 4; the one-way valve 8 and the gate valve 6 are used for controlling the liquid to be filled into the airbag 1 and discharged from the airbag 1; and the static stiffness of the air spring is adjusted by decreasing or increasing the air volume in the airbag 1.
Description
One, technical field:
The present invention relates to a kind of vehicle air suspension and use pneumatic spring.The pneumatic spring of this built-in helical spring and topping up combination 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 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.In the rigidity of pneumatic spring was regulated, people had ignored owing to optional standard series air bag rigidity and the static stiffness that concrete vehicle requires the difference of rigidity to need are regulated.And often because the difficulty that the static stiffness of air bag does not match and caused its dynamic rate to regulate.In the passive type airsuspension system then the static stiffness of air bag not match be to cause the serious major reason of side-sway in the vehicle operating.
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 effectively regulate air spring static rigidity, and make-up air spring dynamic rate improves the vehicle anti-roll capability fast, reduces the composite air spring of vehicle side-sway.
Solution of the present invention is: this composite air spring by built-in helical spring and topping up combination is combined by air bag 1, upper mounting plate 2, last locating stud 3, helical spring 4, following locating stud 5, gate valve 6, lower installation board 7 and one-way valve 8.On the central position of the inner plane of upper mounting plate 2 and lower installation board 7, install locating stud 3 and following locating stud 5, the top of helical spring 4 is enclosed within on the locating stud 3, and the bottom is enclosed within down on the locating stud 5; The clean interior outage degree of the air bag 1 the when free height of helical spring 4 is equal to or slightly greater than vehicle maximum ride height; Gate valve 6 is installed on the lower installation board 7 with one-way valve 8; The quiet rigidity of pneumatic spring is regulated: in air bag 1, charge into chemical combination liquid via one-way valve 8, the chemical combination liquid that charges into has occupied the volume in the air bag 1, has reduced the gas actual volume in the air bag 1, has improved the quiet rigidity of pneumatic spring; Otherwise, discharge the part chemical combination liquid that has charged into by gate valve 6, just reduced the quiet rigidity of pneumatic spring; The dynamic compensation of pneumatic spring dynamic stiffness: when vehicle was in maximum ride height, helical spring 4 is in did not have compression or small amount of compression state, and the rigidity of pneumatic spring is by determining according to the inflation pressure of load request and air actual volume in the air bag 1 in the air bag 1; Vehicle is in when using ride height always, and helical spring 4 is in compressive state, and the rigidity of pneumatic spring is by determining according to the inflation pressure of load request and the rigidity of air actual volume in the air bag 1 and helical spring 4 in the air bag 1; When vehicle was in minimum ride height, helical spring 4 was in further compressive state, and the rigidity of pneumatic spring is by determining according to the air actual volume in the inflation pressure of load request and the air bag 1 and the rigidity of helical spring 4 in the air bag 1; When vehicle dynamic load increase at the volley, upper mounting plate 2 moves down at the effect lower compression air bag 1 of dynamic load, simultaneously compression helical spring 4; Along with upper mounting plate 2 moves down under the effect of dynamic load; The elastic anchorage force of helical spring 4 can increase thereupon, and the part dynamic load of balance vehicle body stops the inclination of vehicle body and leans forward and swing back; Reduce the side-sway of vehicle body when advancing, improve the dynamic stability and the travelling comfort of vehicle body.
The present invention is simple in structure, and is with low cost, easy for installation, and reliable performance is a kind ofly in the passive type airsuspension system, can effectively regulate air spring static rigidity, and its dynamic rate of timely compensation reduces the method for vehicle side-sway; Also can be through changing helical spring rigidity and adapting to the requirement of different automobile types with decrement.
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 static stiffness of this pneumatic spring is regulated: in air bag 1, charge into chemical combination liquid via one-way valve 8; The chemical combination liquid that charges into has occupied the volume in the air bag 1; Reduce the gas actual volume in the air bag 1, improved the quiet rigidity of pneumatic spring; Otherwise,, just reduced the quiet rigidity of pneumatic spring by the chemical combination liquid that gate valve 6 discharge sections have charged into; The dynamic compensation of pneumatic spring dynamic stiffness: when vehicle dynamic load increase at the volley, upper mounting plate 2 moves down at the effect lower compression air bag 1 of dynamic load, simultaneously compression helical spring 4; Along with the effect lower compression air bag 1 of upper mounting plate 2 in dynamic load moves down; The elastic anchorage force of helical spring 4 can increase thereupon, and the part dynamic load of balance vehicle body stops the inclination of vehicle body and leans forward and swing back; Reduce the side-sway of vehicle body when advancing, improve the dynamic stability and the travelling comfort of vehicle body.
