Description
Technical field:
The present invention relates to a kind of highway transport vehicle unbalance-loading detecting device, mainly be applicable to and adopt the highway transport vehicle of leaf spring, belong to highway transport vehicle safety detection technology field as suspension system.
Background technology:
Highway transport vehicle unbalance-loading is the factor that causes that the traffic safety accident is very important, and particularly vehicle unbalance-loading causes that very easily rollover, goods come off under situations such as high speed, emergency turn, thereby causes pernicious traffic hazard.Existing highway haulage vehicle load-carrying measuring method relates generally to the weighing of vehicle axle weight, gross combination weight, and the lack of uniformity that seldom relates to each load of vehicle is the detection of vehicle unbalance-loading situation.
Summary of the invention:
The object of the present invention is to provide a kind of highway transport vehicle unbalance-loading detecting device, judge the vehicle unbalance-loading situation, reduce the traffic safety contingency occurrence probability by detecting vehicle reach both sides load difference.
Above-mentioned purpose of the present invention is achieved in that accompanying drawings is as follows:
A kind of highway transport vehicle unbalance-loading detecting device, it comprises semiconductor laser 7, photopotential dependent sensor 6 and catoptron 4, described semiconductor laser 7, photopotential dependent sensor 6 and catoptron 4 are installed on leaf spring 1 outside, vehicle bridge both sides respectively, semiconductor laser 7 wherein and photopotential dependent sensor 6 are fixed in the outside, leaf spring 1 centre position side by side, catoptron 4 is fixed in the same side and closes near leaf spring 1 end, promptly on hanger 2 or the spring abutment 9; The minute surface of catoptron 4 is right against the light-sensitive surface of photopotential dependent sensor 6, the line laser of semiconductor laser 7 emissions overlapped with photopotential dependent sensor light-sensitive surface center through mirror reflects when vehicle was unloaded, and the full load reflection ray drops in photopotential dependent sensor 6 light-sensitive surfaces.
Described semiconductor laser 7 and photopotential dependent sensor 6 are fixed in the middle box body 5, catoptron 4 is fixed in another box body 3, two box bodys 5,3 grip by anchor clamps, two box bodys 5,3 relative position in the horizontal direction can be regulated, and its horizontal range will be by the elasticity coefficient size decision of spring.
Independently use the automobile of leaf spring for an axle, the installation site of box body 3 can change, its particular location will be decided by the distortion size that this device element is installed side vehicle dead axle lotus leaf spring when reaching ratings, will guarantee that in principle semiconductor laser sent when axle load was lower than specified dead axle lotus 110% light is through all dropping on after the mirror reflects on the light-sensitive surface of photopotential dependent sensor; And the automobile of the shared leaf spring of diaxon, the installation site of middle box body 5 can change, and the change in location principle is consistent with the former.
During the vehicle carrying, leaf spring 1 is out of shape because of being subjected to loading, make laser beam principal direction and catoptron 4 normals present an angle and then cause light beam after direct reflection, to produce certain skew, thereby the light spot position on photopotential dependent sensor 6 light-sensitive surfaces is changed.Side-play amount is directly proportional with the corner amount, and leaf spring 1 deflection is relevant with load weight and running velocity, and when moving in stationary vehicle or with certain speed, the deflection of leaf spring 1 becomes dull linear relationship with dead weight capacity.If it is more even that carload distributes, both sides photopotential dependent sensor 6 detects the signal basically identical that obtains; If there is bigger unbalance loading situation to exist, two sensors detection gained signal difference is bigger during stationary vehicle, and the sort signal difference also will further be amplified during vehicle movement.The special ruuning situation if jolt etc., because the impact that vibration produces causes both sides sensor gained load value signal bigger difference to occur, but this species diversity is a kind of transient change, is not a constant value, and this situation will can not be judged as unbalance loading.In case so after the vehicle loading unbalance loading met or exceeded certain certain value, both sides sensor gained signal compared after treatment, the absolute value that obtains difference will continue to remain on more than or equal to a certain setting, thereby can reach a conclusion---vehicle unbalance-loading.
Beneficial effect of the present invention: this device has advantages such as simple in structure, easy for installation, that dynamic response is good, measuring accuracy is high, long-term work is stable, and has from the function of demarcating.The unbalance loading that therefore can be widely used in various highway transport vehicles detects, monitoring, for the highway transport vehicle safe operation provides certain technical guarantee.

Embodiment:
Below in conjunction with the accompanying drawing illustrated embodiment the present invention is described in further detail:
Consult Fig. 1～4: a kind of highway transport vehicle unbalance-loading detecting device that the present invention relates to, be specially adapted to adopt the highway transport vehicle of leaf spring as suspension system, comprise the catoptron 4 that is installed on same reach both sides, photopotential dependent sensor 6, semiconductor laser 7, catoptron 4 places in the box body 3, box body 3 is fixed near leaf spring 1 end by corresponding anchor clamps, the outside as near the leaf spring 1 of hanger 2 or spring abutment 9, photopotential dependent sensor 6, semiconductor laser 7 is horizontal Tile and fixedly places in the middle box body 5, and middle box body 5 also is fixed in the outside at leaf spring 1 middle part by corresponding anchor clamps.Catoptron 4 and photopotential dependent sensor 6 are positioned at the same side of leaf spring 1, and both are near spring position simultaneously or are in simultaneously away from spring position; By regulating the position of box body 3 or middle box body 5, guarantee catoptron 4 mirror alignment photopotential dependent sensors 6 light-sensitive surfaces, and when vehicle is unloaded, the line laser of semiconductor laser 7 emissions overlaps with photopotential dependent sensor 6 light-sensitive surface centers after catoptron 4 reflections, and the full load reflection ray drops in photopotential dependent sensor 6 light-sensitive surfaces.
When vehicle carries, leaf spring 1 is out of shape because of the effect that is subjected to load, the position relation of catoptron 4 and photopotential dependent sensor 6 is changed, promptly the angle on two surfaces changes, the laser beam that semiconductor laser 7 sends will produce certain skew after by catoptron 4 direct reflections, and photopotential dependent sensor 6 will come the sense vehicle load condition by detecting this skew.The photopotential dependent sensor 6 that is installed on same reach both sides detects two load signal values respectively, if these two signal values compare by after handling, maintains a certain constantly in big difference all the time, then can judge this vehicle unbalance-loading.
