Abstract
An air spring in an automobile suspension system is of vital importance to enhancement of the riding comfort and the comfortableness of vehicles, to protection of roads and cargoes and to overload restrictions. Currently, in common passive-type air suspension systems, the static stiffness of airbag products of standard series cannot be adjusted in a personalized manner according to the actual needs of vehicles, and dynamic stiffness of springs cannot be effectively compensated, leading to serious side swing of vehicles when the vehicles are running and making passengers and drivers dizzy and uncomfortable. To solve this problem, the utility model provides an air spring with combination of a built-in spiral spring and an auxiliary air chamber. With respect to the stiffness combination, the airbag stiffness plays a main role, and the stiffness of the spiral spring plays an auxiliary role and is matched with the pre-compression, thereby providing a convenient method for improving the dynamic stiffness characteristics of existing standard airbags. The static stiffness of the air spring can be effectively adjusted by the auxiliary air chamber. The air spring of the utility model is simple in structure, rapid and reliable in response and low in cost.
Description
One, technical field:
The present invention relates to a kind of vehicle air suspension and use pneumatic spring.This composite air spring by built-in helical spring and auxiliary tank 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; The quiet rigidity that adds the air bag product of standard series can not be carried out the personalization adjusting according to the actual demand of vehicle; 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.
Three, summary of the invention:
The object of the invention will be developed a kind of low cost exactly; Simple and reliable, can compensate the air bag dynamic stiffness fast; Can also carry out personalization to the quiet rigidity of air bag product according to the actual demand of vehicle and regulate, improve the vehicle anti-roll capability, reduce the composite air spring of vehicle side-sway.
Solution of the present invention is: this composite air spring by built-in helical spring and auxiliary tank combination is combined by air bag 1, upper mounting plate 2, last locating stud 3, helical spring 4, auxiliary tank 5 and lower installation board 6.With locating stud 3 and auxiliary tank 5 on the vertical center line location and installation of upper mounting plate 2 and lower installation board 6; The top of helical spring 4 is enclosed within on the locating stud 3; The bottom is enclosed within on the auxiliary tank 5; The external volume of auxiliary tank 5 is promptly occupied volume unnecessary in the air bag by the external volume of auxiliary tank 5 by deciding according to the actual demand of vehicle and the difference of the quiet rigidity of selected standard air bag product, makes the compound actual demand of quiet rigidity of air bag; 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.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 is in minimum ride height; Helical spring 4 is in further compressive state; 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; This moment this complex spring the rigidity of rigidity during greater than commonly used ride height, help high vehicle speeds; 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 of method that in the passive type airsuspension system, can effectively reduce the 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: at first; By the external volume of confirming auxiliary tank 5 according to the difference of the actual demand of vehicle and the quiet rigidity of selected standard air bag product; Promptly occupy volume unnecessary in the air bag, make the compound actual demand of quiet rigidity of air bag by the external volume of auxiliary tank 5.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.
