The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Example 1: referring to Fig. 1, Fig. 2 and Fig. 3, a kind of Leaf Spring Suspension vehicle self-weighing system, comprises displacement pickup and mounting bracket, electronic control unit (ECU), read-out, demarcation knob and rattail.Its installation form is: in front suspension, as shown in Figure 1, displacement pickup 4 is arranged between displacement pickup upper bracket 5 and panel spring hold-down plate 6, and displacement pickup 4 is hinged with it respectively, wherein displacement pickup base portion is connected with sensor upper bracket 5, and pull bar part is connected with panel spring hold-down plate 6.When in cargo process, weight changes, leaf spring deforms under load, on the relative vehicle frame of pars intermedia branch of leaf spring, moves, and can obtain the deflection of leaf spring by displacement pickup; In back balance suspension, as shown in Figure 2, the upper end (base portion of displacement pickup) of displacement pickup 4 is hinged with the upper bracket of bumper 7, and lower end (the pull bar part of displacement pickup) is hinged with the support of lower thrust rod 10, and the displacement pickup installation form of jackshaft and back axle is consistent.For back balance suspension, on more satisfactory level road, along with the increase of load carrying ability, leaf spring two ends are moved under the promotion of bridge, and on the displacement that moves equate, the displacement that two displacement pickups detect also equates, for at tilted road surface, or Uneven road situation under, may there is the state that suspension two ends are one high and one low, the now setting of two sensors is necessary, the displacement difference of two sensors, but the displacement that this displacement has comprised leaf spring carrying pressing and the displacement that leaf spring rotates around balance shaft, thereby the displacement of two displacement pickups need to be averaged and obtained the displacement for calculating.
Fig. 3 has represented the circuit connection state of this system: displacement pickup has three lines, a ground connection, one connects voltage, one is signal wire (SW), the output of this signal wire (SW) be 0 to a certain magnitude of voltage between maximum voltage, this magnitude of voltage is relevant with displacement.Signal is transferred to and in ECU, first carries out analogue to digital conversion, convert analog signal to digital signal, in ECU, brush in advance information and program into corresponding vehicle, during according to vehicle empty mass, front plate spring rigidity and zero load, read in and treated displacement transducer signal, light condition is demarcated; In the time of fully laden, use and demarcate knob input measurement load and be fully loaded with demarcation, ECU records the signal value of each displacement pickup when being fully loaded with simultaneously, calculates the practical stiffness value of leaf spring after vehicle by the formula in claims, completes calibration process.Demarcate knob and can export two signals, the signal of exporting when rotation, for preference pattern, is pressed the signal of demarcating knob output for determining.General run of thins shows the total mass under screen display vehicle current state, in the time of level and static or smooth running, show that data are more accurate, after demarcating knob, rotation can enter fully loaded (zero load) calibration mode, now show that a certain position of screen display load value is in flicker, demarcate knob change flicker bit by rotation, can change the numerical value of selected flicker bit by pressing demarcation knob, thereby the actual gross weight that input fully loaded (zero load) is demarcated, input rear rotation demarcation set point value and determined position, pressed this knob and complete fully loaded (zero load) demarcation.After this system of startup, this system just can be worked voluntarily, and chaufeur can, according to the complete vehicle weight control loading amount showing, save the trouble of freighting back and forth and unloading and weighing, and has improved logistic efficiency and has reduced corresponding cost.
Example 2: referring to Fig. 1, Fig. 2 and Fig. 4.The arrangement form of Fig. 1 and Fig. 2 is similar to example 1.Fig. 4 can see that one has 4 displacement pickups 4, and wherein front axle has two, and rear-axle balance suspension place has two, with Fig. 3 ratio, front axle is many one, and this is because the vehicle of drive form 8 × 4 has two front axles and plate spring suspension structure, before and after this two nested structure, arranges, 1.5 to 2 meters of spacing, for the vehicle of drive form 8 × 4, the structure shown in Fig. 1 has two covers, on frame assembly 2 in tandem, structure shown in Fig. 2 has a set of, consistent with the vehicle of drive form 6 × 4.Therefore have 4 displacement pickups on Fig. 4.In the time of system works, ECU need to receive the signal of Zhe Si road displacement pickup and carry out digital to analogy conversion.The now demarcation of system need to be brushed the program into corresponding drive form 8 × 4 in advance, and inputs the rigidity value of first and second front axle place steel spring.Unloaded timing signal, under light condition, gross empty vehicle mass, two front plate spring rigidity of input vehicle, in definite, ECU can record the signal value of corresponding states bottom offset sensor; Fully loaded timing signal uses to be demarcated knob input measurement load and be fully loaded with demarcation, and ECU records the signal value of each displacement pickup when being fully loaded with simultaneously, calculates the practical stiffness value of leaf spring after vehicle by the formula in claims, completes calibration process.Now calibration process is identical with example 1.The work that in example 1 and example 2, the calibration process of narration is done before dispatching from the factory for vehicle, when vehicle is delivered in user's hand, this system can normally be worked, chaufeur only needs to start this system in use, just can on read-out, see the total mass of vehicle under current state.
