Abstract
The utility model relates to an adjustable damper airbag which comprises an upper air cavity, a lower air cavity; the upper air cavity is connected with the lower air cavity through an upper air cavity connecting rubber belt and a lower air cavity connecting rubber belt; an upper air cavity seal rubber ring is arranged on the top part of the upper air cavity and is fixed on a damper support base; a lower air cavity seal support base is arranged on the bottom of the lower air cavity and is arranged on the damper; the upper air cavity seal rubber ring, the upper air cavity, the upper and lower air cavity connecting rubber belts , the lower air cavity and the lower air cavity seal support base form a sealed air chamber; one side of the upper air cavity is communicated with an inflation tube; the inflation tube is connected with an electric inflation pump; a control switch in driving cab is connected with the electric inflation pump. The adjustable damper airbag has the beneficial effects that the adjustable damper airbag occupies small space and is mounted on the exterior of the damper and enables the damper and oil seal to be surrounded by high pressure gas in air cavity; the interior pressure of the damper is lower than the exterior air pressure so that the sealing performance is increased; the oil leakage of damper is reduced and the service life of damper is prolonged.
Description
Technical field
The utility model relates to the vehicular spare parts field, relates in particular to a kind of adjustable shock absorber air bag.
Background technology
The elastic element that is used for automobile absorber in the market has coil spring, spring steel plate, elastic torsion bar etc., the problem of their function and existence is as follows: 1, coil spring is mainly used on the car bumper, it is little to take up room, be fit to be installed on independent suspension, shortcoming is aging easily weak, permanent deformation takes place, and car body is reduced; Fracture easily, safety performance is low, and damping effect is general.2, spring steel plate is mainly used in high capacity waggon, passenger vehicle, and load carrying ability reaches, and the safety performance height is fit to be installed on whole vehicle bridge, and shortcoming is to take up room too, poor flexibility, and damping effect is poor.3, the elastic torsion bar is mainly used in the car bumper, and share of market is low, and shortcoming is to take up room greatly, poor flexibility, and safety performance is low.
The utility model content
The purpose of this utility model provides a kind of adjustable damper air bag, and the above-mentioned safety performance that the existing elastic element such as coil spring, spring steel plate, elastic torsion bar that is used for automobile absorber exists is low, damping effect general to overcome, deficiency such as big takes up room.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of adjustable damper air bag comprises air chamber, following air chamber, described go up air chamber and following air chamber by upper and lower air chamber be connected the rubber tape connection with about fore and aft motion; Last air chamber top is provided with the air chamber O-ring seal and is fixed on the bumper upper bracket; Following air chamber bottom is provided with down the air chamber sealed support and is arranged on the bumper; Describedly go up the air chamber O-ring seal, go up air chamber, upper and lower air chamber connects rubber tape, down air chamber, the air chamber sealed support forms a leak free energy chamber down, can form an elastic element after the inflation, wherein said air chamber O-ring seal and following air chamber sealed support seal; One side of last air chamber is communicated with appendix, and described appendix connects electric inflating pump, and operator's compartment inner control switch is connected with electric inflating pump to control its unlatching, and described operator's compartment inner control switch can be provided with a plurality of gears, controls electric gas-filled pump work.
The beneficial effect of adjustable damper air bag described in the utility model is: can make the Level Change of car body, car body raises during the road conditions difference, strengthens the road surface crossing ability of automobile; When road conditions were general, car body was controlled at normal height, and its in-to-in pressure gas strengthens the comfort level of automobile; Road conditions better or when running at high speed car body reduce, centre of gravity of vehicle sinks, and strengthens the stability of automobile.In addition, the utility model takes up room little, is installed in the outside of bumper, anti-shock fluid and oil sealing are under the encirclement of energy chamber inner high voltage gas, and the bumper internal pressure is lower than external pressure, can increase sealing property, alleviate the bumper leakage of oil, prolong the service life of bumper.
Description of drawings
Describe the utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the described adjustable damper air bag of the utility model embodiment.
Among the figure:
1, bumper upper bracket; 2, go up the air chamber O-ring seal; 3, go up air chamber; 4, upper and lower air chamber connects rubber tape; 5, following air chamber; 6, following air chamber sealed support; 7, bumper; 8, appendix; 9, electric inflating pump; 10, operator's compartment inner control switch.
The specific embodiment,
As shown in Figure 1, the described adjustable damper air bag of the utility model embodiment comprises air chamber 3, following air chamber 5, described go up air chamber 3 and following air chamber 5 by upper and lower air chamber be connected rubber tape 4 connections with about fore and aft motion; Last air chamber 3 tops are provided with air chamber O-ring seal 2 and are fixed on the bumper upper bracket 1; Following air chamber 5 bottoms are provided with down air chamber sealed support 6 and are arranged on the bumper 7; Describedly go up air chamber O-ring seal 2, go up air chamber 3, upper and lower air chamber connects rubber tape 4, down air chamber 5, air chamber sealed support 6 forms a leak free energy chamber down, can form an elastic element after the inflation, wherein said air chamber O-ring seal 2 and following air chamber sealed support 6 seal; One side of last air chamber 3 is communicated with appendix 8, described appendix 8 connects electric inflating pump 9, operator's compartment inner control switch 10 is connected with electric inflating pump 9 to control its unlatching, and described operator's compartment inner control switch can be provided with a plurality of gears, 9 work of control electric inflating pump.
The principle of work of the described adjustable damper air bag of the utility model embodiment: the height of car body is relevant with chassis bonded assembly elastic element with vehicle body, and elastic force is big more, and car body is high more, and elastic force is more little, and car body is low more.Energy chamber inflation of the present utility model back forms elastic element, and the elastic force size of this elastic element depends on the height of energy chamber air pressure inside.The work of electric inflating pump 9 can be controlled and regulate to operator's compartment inner control switch 10, be input into or the air of the chamber interior that deflates by appendix 8, regulate the energy chamber air pressure inside, make this control cabin become an elastic element that elastic force is variable, thereby can control and regulate the height of car body.
