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, is not intended to limit the present invention.
As shown in Figures 1 to 4, a kind of leaf spring of the present invention hangs four mixed axle vehicle tankers with air bag, comprise vehicle frame 1, vehicle frame 1 below arranges four axletrees 2, the axletree 2 that is positioned at front end all is installed on the bottom of vehicle frame 1 with the axletree 2 that is positioned at the rear end 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, and load sensing valve 3 is controlled the air pressure of air bag suspension gear.
Vehicle frame 1 below is provided with crossbeam 4, and load sensing valve 3 is fixed in crossbeam 4 belows by the first adapter plate 5.
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 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 the 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 large 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 capable of regulating and hang air bag 8 air pressure and make axle load even in addition.But the result of calculating is common and actual value has certain error, and regulating load sensing valve 3 by computing value may the out of reach requirement.In order conveniently to regulate, be provided with air-pressure gauge 27 on the pipeline that connects between the control end of lifting control cock 6 and suspension air bag 8, when reaching requirement, the axle load distribution records its atmospheric pressure value, in order to can regulate rapidly and accurately next time.
During heavy duty, air bag suspension gear and leaf spring hang and can mate, and make four axletrees, 2 axle loads balanced; By hand-control device, forward and backward diaxon is raised up when unloaded, reduce wear on tyres.When heavy duty 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 be according to suffered LOAD FOR out, 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 air bag 8 can not change along with height change.Therefore, hang air bag 8 and hang on leaf spring and hang coupling for making, need to change to regulate according to the leaf spring amount of deflection to hang air bag 8 air pressure, make leaf spring place axletree 2 even with air bag place axletree 2 stands under load.Concrete by at the leaf spring axletree 2(of place the second axle) 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 is fixed with longeron 15, longeron 15 is main supporting member, be provided with longeron between vehicle frame 1 and 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 suspension supporting leg 17, hang supporting leg 17 and hang air bag 8 tops, 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 longeron 15, crossbeam brace panel 19 is welded to connect with longeron 15 and crossbeam 4, play the assistant reinforcement effect, hang to arrange between supporting leg 17 and longeron 15 and hang reinforced rib 20, hanging longeron 15 parts at 20 pairs of supporting legs of reinforced rib and the main stress point of air bag place strengthens, crossbeam 4 is strengthened gussets 21 with suspension supporting leg 17 use and is welded to connect, and hangs to reduce the moment of torsion that supporting leg 17 bears, and suspension supporting leg 17 places all are welded with reinforcement channel-section steel 22 in the left and right.
It should be noted that at last: these are only the preferred embodiments of the present invention; be not limited to the present invention; although with reference to embodiment, the present invention is had been described in detail; for a person skilled in the art; it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing; perhaps part technical characterictic wherein is equal to replacement; but within the spirit and principles in the present invention all; any modification of doing, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
