Description

Automobile bellows type air spring and shock absorption device
Technical field
The utility model relates to the carrying and the damping field of automobile, particularly a kind of bellows type air spring and shock absorption device that is used for automobile.
Background technology
The elastic carrier part of miniature car (car, utility van and commercial vehicle etc.) all is two devices that separate with bumper basically at present, and they have function separately separately, and have occupied bigger space.The elastic carrier part mainly adopts traditional steel spring; And bumper all extensively adopts hydraulic damper, two-way telescopic shock absorber and damping spring etc., as the disclosed a kind of automobile damping spring buffer gear of Chinese patent CN2813999 is exactly to adopt the damping spring that is installed on the axletree, although it is nested with the bump rubber of being made by elastomeric material on damping spring, its effect can't be desirable.In order to improve comfort level, people have proposed the improvement project of many bumpers, but its structure more complicated all.
Summary of the invention
Problem to be solved in the utility model is: a kind of automobile bellows type air spring and shock absorption device that integrates elastic carrier device and bumper is provided.
The technical scheme that addresses the above problem is: the automobile bellows type air spring and the shock absorption device that are provided comprise elastic carrier part and bumper.Special feature of the present utility model is: said elastic carrier part is first air bag that occupies side space under the inner cylinder tube piston, said bumper is second air bag that occupies inner cylinder tube piston superjacent air space, be provided with first air inlet valve and first blow off valve that can be interconnected between first air bag and second air bag, first air bag is connected with source of the gas by second air inlet valve, first air bag is communicated with outside atmosphere by the second series air valve, the piston rod and the outer sleeve of inner cylinder tube are connected, this outer sleeve is enclosed within outside the inner cylinder tube, inner cylinder tube is connected with axletree, outer sleeve and body contact.The pressurized air of external air source enters first air bag by second air inlet valve, and the compression sky in first air bag can charge into second air bag by first air inlet valve.First air bag is mainly used in bearing vehicle body weight, and second air bag is mainly used in damping, buffering, and outer sleeve inner cylinder tube relatively slides, and plays the guiding protective effect.
The second above-mentioned air bag is the India rubber tube of spiral preferably, its damping effect the best.
In order to make the piston inner cylinder tube that directly do not rub, reduce wearing and tearing and heating, can be provided with the ball that contacts with the inner cylinder tube inwall in the periphery of piston.
The first above-mentioned air inlet valve, first blow off valve, second air inlet valve and second series air valve can be check valve or electromagnetic valve, and the former is mainly used in ordinary vehicle type, and the latter is mainly used in middle and high shelves car.
The utility model has the advantages that: simple in structure, compact, length is shorter, so the position of car bonnet can reduce; The air bellow of this device belongs to the nonlinearities change spring, helps to absorb to impact, and feels comfortable so travel; Because nonspring carried mass is little, steering operation is more laborsaving; In addition, this device is by to the filling exhaust and piston is raise or reduce of first air bag, thereby adjusts chassis height, to adapt to the situation of different road surfaces, road conditions, makes roadlice have certain cross country power; Piston moves up during the damping of this device, and air bag is volumetric shrinkage up and down, and vertically ratio strengthens, and gasbag ektexine is understood urgent cylinder barrel and piston rod, plays the brake action of similar brake; In addition,, can adjust the air pressure of bumper capsule (second air bag), to guarantee to produce enough dumping forces according to the variation of automobile load.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
The specific embodiment
Embodiment 1 is used for vehicle front as shown in Figure 1.Inner cylinder tube 1 adopts solid drawn pipe to make, and second air bag 2, piston 3 and first air bag 4 are housed in it from top to bottom successively.The periphery of piston 3 is equipped with double ball 5, and ball 5 rolled along the inner cylinder tube inwall when piston moved.Second air bag 2 adopts the sebific duct of three-decker to spiral and forms, and its internal layer is the strong elastic plastic cement, and the middle level is the intensified nylon net, and skin is for antifriction rubber and wear-resisting stupefied circle is arranged, and the laminar texture of first air bag 4 is identical with second air bag.First air inlet valve 6 and first blow off valve 7 are housed on the piston 3, and the two-port of air valve lays respectively in first air bag 4 and second air bag 2, promptly can be interconnected by two air valves between two air bags.Outer sleeve 8 is enclosed within outside the inner cylinder tube 1 as guide, and inner sleeve piston rod 9 is by a plane ball bearing of main shaft 11 and a body contact.Link span 10, ball bearing of main shaft 11 and outer sleeve all are sleeved on the piston rod 9 in this example, then with nut 12 locking, wherein link span 10 and body contactes.Owing to be provided with ball bearing of main shaft 11, when front-wheel turns to, can rotate thereupon with axletree bonded assembly inner cylinder tube 1 and outer sleeve 8.The base 13 of inner cylinder tube 1 is provided with support 14, and support 14 is connected with axletree.Second air inlet valve 15 and second series air valve 16 also are housed on the base 13 of inner cylinder tube 1, and their port all places in first air bag 4, and the another port of second air inlet valve 15 links to each other with the source of the gas of automobile, and the another port of second series air valve 16 communicates with atmosphere.Also be provided with a rubber cushion blocks 17 on the inner sleeve top, be used for supporting tare after the air bag emptying.
Each air valve in this example can adopt the general-duty check valve, and it is opened pressure and is controlled by spring.Pressurized air gives first air bag 4 inflations by the setting pressure of second air inlet valve 15, and unnecessary gas is by 16 emptyings of second series air valve; Meanwhile, the pressurized air in first air bag 4 is given the inflation of second air bag 2 (shock-absorption air bag) by first air inlet valve 6 again.Tare is mainly born by first air bag 4 by piston rod, piston; When automobile pitched, the vibrations that produced were mainly born by second air bag 2, realized damping.
