The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in restriction the present invention.
As shown in Figures 1 to 4, a kind of leaf spring of the present invention and air bag hang four flow container superimposed trailers using with, comprise vehicle frame 1, vehicle frame 1 below arranges four axletrees 2, the axletree 2 that is positioned at the axletree 2 of front end and is positioned at the rear end all is installed on the bottom of vehicle frame 1 by the air bag suspension gear with bont, two axletrees 2 in the middle of being positioned at hang by leaf spring and are installed on vehicle frame 1 bottom, axletree 2 in the middle of being positioned at is equipped with measures the load sensing valve 3 that the leaf spring amount of deflection changes, the air pressure of load sensing valve 3 control air bag suspension gears.
Consult Fig. 4; load sensing valve 3 one ends connect storage tank 23; on the air inlet pipe 24 of storage tank 23 compressor protection switch 25 is set; between storage tank 23 and the load sensing valve 3 in-line filter 26 is set; load sensing valve 3 other ends connect lifting control cock 6; air bag suspension gear with bont comprises lifting air bag 7 and hangs air bag 8, promotes control cock 6 and connects lifting air bag 7 and hang air bag 8.
Initial condition is regulated the relative position of axletree pipe link 12 and second adapter plate 14, and as axletree pipe link 12 is up lifted, angular adjustment bar 9 diminishes with pipe link 10 angles, hangs air bag 8 pressure and increases; As with axletree pipe link 12 toward descending, angular adjustment bar 9 becomes big with pipe link 10 angles, hangs air bag 8 pressure and reduces.Axle load when calculating heavy duty and leaf spring amount of deflection change to adjust and hang air bag 8 air pressure and make axle load even in addition.But the result who calculates is common and actual value has certain error, and regulating load sensing valve 3 by computing value may the out of reach requirement.For convenience of regulating, the pipeline that connects between the control end of lifting control cock 6 and the suspension air bag 8 is provided with air-pressure gauge 27, records its atmospheric pressure value when the axle load distribution reaches requirement, in order to can regulate rapidly and accurately next time.
Air bag suspension gear and leaf spring hang and can mate during heavy duty, make the 2 axle load equilibriums of four axletrees; By hand-control device forward and backward diaxon is raised up when unloaded, reduce wear on tyres.Heavy duty the time must make the axle load of the axle load of air bag suspension place and leaf spring suspension place even, because leaf spring is rigidity, air bag is flexible, the leaf spring amount of deflection change with stressed be corresponding, can come out according to suffered LOAD FOR, and air bag is under the condition of normal operation, and height can be regulated voluntarily, its stressed only with hang air bag 8 internal gas pressures relevant (area of thrust surface are fixed).The pressure that hangs in the air bag 8 can not change along with height change.Therefore, hang coupling for making suspension air bag 8 hang on leaf spring, need to change adjusting according to the leaf spring amount of deflection and hang air bag 8 air pressure, make leaf spring place axletree 2 and air bag place axletree 2 stands under load even.Concrete by second of the axletree 2(of leaf spring place) install load sensing valve 3 additional, change according to the leaf spring amount of deflection and regulate suspension air bag 8 air pressure and reach this purpose.
Consult Fig. 2, crossbeam 4 fixedly has longeron 15, longeron 15 is main supporting member, be provided with longeron between vehicle frame 1 and the longeron 15 and strengthen angle steel 16,16 pairs of longerons 15 of longeron reinforcement angle steel are connected the plane with the vehicle frame 1 of top tank body and strengthen, hanging air bag 8 is fixed on the suspension supporting leg 17, hang supporting leg 17 and hang top, air bag 8 centers and be provided with loading plate 18, loading plate 18 is used for the moment of torsion that carrying longeron 15 passes over, be provided with crossbeam brace panel 19 between crossbeam 4 and the longeron 15, crossbeam brace panel 19 is welded to connect with longeron 15 and crossbeam 4, play auxiliary booster action, hang to arrange between supporting leg 17 and the longeron 15 and hang reinforced rib 20, hang longeron 15 parts at 20 pairs of supporting legs of reinforced rib and the main stress point of air bag place and strengthen; Crossbeam 4 and hang supporting leg 17 usefulness and strengthen gusset 21 and be welded to connect hangs the moment of torsion that supporting leg 17 bears to reduce, about hang supporting leg 17 places and all be welded with reinforcement channel-section steel 22.
It should be noted that at last: above only is the preferred embodiments of the present invention; be not limited to the present invention; although the present invention has been described in detail with reference to embodiment; for a person skilled in the art; it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing; perhaps part technical characterictic wherein is equal to replacement; but it is within the spirit and principles in the present invention all; any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
