Abstract
The utility model relates to a composite air spring formed by combining an air bag and a built-in auxiliary air chamber, consisting of the air bag (1), an upper installation plate (2), a lower installation plate (3) and the auxiliary air chamber (4). The composite air spring is characterized in that the auxiliary air chamber (4) is arranged and fixed on the upper plane of the lower installation plate (3). In the composite air spring, the auxiliary air chamber (4) with a calculated or test volume is additionally arranged in the air bag of the existing air spring, and the size in the air bag is occupied so as to adjust the static stiffness of the air spring. The composite air spring is simple in structure, low in cost and convenient and practical.
Description
One, technical field:
The present invention relates to a kind of vehicle with the air bellow of passive type air suspension and its quiet rigidity control apparatus and method.This air bellow 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 technology:
In order to improve ride of vehicle, improve the traveling comfort of taking, alleviate the damage of vehicle to road and goods, developed country has adopted air bellow widely in the suspension system of its carrier vehicle.China recent years is also being widelyd popularize and mandatory employing air bellow.In the air bellow technology of constantly development, in order further to improve the rigidity regulating characteristic of air bellow, 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 rigidity of air bellow is lower; Main is: the quiet rigidity of the Series Air Springs of standard configuration can't be carried out personalization according to the parameter that car load requires and regulated; Caused the vehicle side-sway phenomenon that is in operation more serious, it is dizzy and uncomfortable that occupant and chaufeur are produced, and seriously influences occupant's the traveling comfort and the safe driving of chaufeur.
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 to the quiet rigidity of the air bellow 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: this composite air spring by air bag and the combination of built-in auxiliary tank is combined by air bag 1, upper mounting plate 2, lower installation board 3, auxiliary tank 4.On plane on the lower installation board 3, install and fix auxiliary tank 4; Auxiliary tank 4 can be processed 5 face closures; Lower plane is formed an osed top air chamber by the last plane of lower installation board 3; Also can process 6 face fully enclosed independent air chambers, adopt gluing or other fixing means is installed on the upper mounting plate 2 or on the lower installation board 3.Auxiliary tank 4 also can be made into the special-shaped shape of other suitable air bag (1) inner spaces; Auxiliary tank 4 can select for use metal or non-metallic material to make, and can be made into hollow or solid; Auxiliary tank 4 can be processed integral type, also can be made into the burst assembly type; The quiet rigidity control method of this composite air spring is: calculate the external volume of confirming auxiliary tank 4 according to the actual demand of vehicle and the difference of the quiet rigidity of selected standard air bag product earlier, make auxiliary tank 4 according to result of calculation then; Adopt welding or method such as gluing to be fixed on auxiliary tank 4 on the lower installation board 3 at last or on the upper mounting plate 2; Auxiliary tank 4 has occupied the effective volume of gas in the air bag 1, thereby has reached the purpose of heightening the quiet rigidity of air bellow, satisfies the rational Match of vehicle to the quiet rigidity of air bellow.
The present invention is simple in structure, and is with low cost, easy for installation, and dependable performance is a kind of combined air gas spring that in the passive type airsuspension system, can carry out rational Match and personalized adjusting effectively to the quiet rigidity of air bellow.
Four, description of drawings:
Accompanying drawing 1 is a structure principle chart of the present invention.
Five, the specific embodiment:
The specific embodiment of the present invention is: calculate the external volume of confirming auxiliary tank 4 according to the actual demand of vehicle and the difference of the quiet rigidity of selected standard air bag product earlier, make auxiliary tank 4 according to result of calculation then; Adopt welding or method such as gluing to be fixed on auxiliary tank 4 on the lower installation board 3 at last or on the upper mounting plate 2; Auxiliary tank 4 has occupied the volume of gas in the air bag 1, thereby has reached the purpose of heightening the quiet rigidity of air bellow, satisfies the rational Match of vehicle to the quiet rigidity of air bellow.
