Detailed description of the invention:
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is retouched clearly and completelyState, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment. Based on the present inventionIn embodiment, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite,All belong to the scope of protection of the invention.
Embodiment 1: as shown in Figure 1: a kind of heavy-duty car air suspension vehicle rear overhang localization method, step is as follows:
(1) the 3 left side air bags 6 of back axle in vehicle are forced into design maximum gas pressure, then use left side altitude valve 7 to left sideAir bag 6 is exitted, and uses orientation tool 2 in deflation course, back axle 3 upper ends in location vehicle frame 1 left side lower aerofoil and vehicleFace is tangent, inflates again to left side air bag 6, makes left air bag 6 highly reach design height H0-1, then demarcates;
(2) the 3 right side air bag (not shown)s of back axle in vehicle are forced into design maximum gas pressure, then use right heightValve (not shown) is exitted to right side air bag, uses orientation tool 2 in deflation course, location vehicle frame 1 right side bottom wingIn face and vehicle, back axle 3 upper surfaces are tangent, again give right side airbag aeration, make right air bag height reach design height H0-2;
(3) continue to inflate to left side air bag 6, reach after the highest design attitude H1-1 to left side air bag 6, carry out left side gasCapsule peak is demarcated;
(4) continue to right side airbag aeration, reach after the highest design attitude H1-2 to right side air bag, carry out right side air bagHigh point is demarcated;
(5) adjust left side altitude valve 7, emit completely to gas in left side air bag 6, left side air bag 6 H2-1 that touches the bottomAfter, carry out left side air bag minimum point and demarcate;
(6) adjust right side altitude valve, emit completely to gas in the air bag of right side, right side air bag touches the bottom after H2-2,Carrying out right side air bag minimum point demarcates.
In above-mentioned six steps, the process of demarcation is to adopt computer to be connected with altitude valve with controller successively, by controllingDevice feeds back to the signal of computer, judges peak and the minimum point of air bag, then carries out record.
In step (1), in the lower end of orientation tool 2 and vehicle, back axle 3 is tangent, and orientation tool 2 upper ends and vehicle frame 1 left sideWhen the contact of side lower aerofoil, be H0-1.
Preferably, preferred, in step (2), the lower end of orientation tool and middle back axle are tangent, and orientation tool 2 upper ends andWhen vehicle frame 1 right side lower aerofoil contacts, be H0-2.
Described H0-1 is identical with H0-2, can guarantee vehicle suspension level in left and right under formation state.
Find out from above-mentioned steps, H0-1 and H0-2 are vehicle frame equilbrium position, i.e. initial position. Herein as zero point, rear overhangFrame can be upwards, move downward, therefore the accurate location of initial point is very important.
As shown in Figure 2: the face that orientation tool 2 contacts with vehicle frame lower aerofoil and perigee distance are exactly H0-1 and H0-2, when inciting somebody to actionOrientation tool 2 is stuck in left and right vehicle frame 1 lower aerofoil, and in the lower surface of orientation tool 2 and vehicle, the upper surface of back axle 3 is as pointWhen contact, illustrate that vehicle frame lower aerofoil and vehicle bridge distance are exactly H0-1 and H0-2.
Adopted after said method, this programme has solved in prior art easily because wrong initial point is located the rear overhang causingFrame is not steady, the problem of resonance of the car.
Use this method in the time that vehicle is positioned, in position fixing process, be not subject to the impact of tire pressure and ground flat degree,Vehicle is tested in out-of-flatness ground, also can be positioned heavy automobile rear suspension accurately.
Meanwhile, after adopting this method to position vehicle, can make air bag in the highest design attitude and minimum design attitudeBetween (being nominal situation), can prevent because of air bag for a long time in minimum point cause balloon surface somewhere concentrate stressed cause damageBad, also can prevent air bag be at the highest notch for a long time draw bad.
As in Figure 3-5, the orientation tool in this programme, comprises the U-shaped plate 8 of horizontally set, this U-shaped plate 8 and detector bar10 are fixedly connected with; The bottom of described detector bar 10 is spherical shape; The lower end of described U-shaped plate 8 is also provided for improving detector barThe reinforcement 9 of 10 stabilitys.
When use, U-shaped plate 8 is stuck on vehicle frame lower aerofoil, along with the variation of air bag height, detector bar 10 will be graduallyMove down, complete location.
Because the lower end of detector bar 10 is that point contacts with vehicle bridge, so the lower end of detector bar 10 is spherical shape, to adapt to vehicle bridgeRadian.
In accompanying drawing of the present invention, only heavy vehicle left side position fixing process is demonstrated, and heavy vehicle is symmetrical structure,Vehicle right side is without carrying out again word and brief description of the drawings.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention. To implementingThe multiple amendment of example will be apparent for those skilled in the art, and General Principle as defined herein is passableIn the situation that not departing from the spirit or scope of the present invention, realize in other embodiments. Therefore, the present invention will can not be limitedIn these embodiment shown in this article, but to meet the widest scope consistent with principle disclosed herein and features of novelty.
