Description
Technical field
This utility model belongs to vehicle mechanical electronic applications and in particular to the calling oneself of a kind of prevention air suspension overloading wagon
Refitting is put.
Background technology
For ensureing loading lorry traffic safety, safeguarding road, avoid the penalty note that overloads, the mode that lorry metering is weighed becomes capable
The focus studied in the industry.In industry, conventional lorry weighting manner mainly has portable dynamic weight method and strain-type dynamic at present
Weight method.Portable dynamic weight method is easy for installation, is easy to carry and flows, but weighing precision is relatively low.Strain-type dynamically claims
Heavy method structure is simple, and weighing precision is high, but is affected very big by speed, and the speed that weighting platform crossed by general strict demand vehicle must be low
In 10km/h.Both Weighing methods are all in a fixed location, take tens squares of places, need special weighman, no
Only efficiency is low, and very consumption wealth takes time and effort.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of self-weighing of prevention air suspension overloading wagon
Device, can facilitate driver to obtain accurately loading lorry gross weight in real time, can efficiently control overweight phenomenon and occur.
In order to achieve the above object, this utility model includes some pressure transducers being arranged on truck air suspension,
All pressure transducers are all connected to electronic control unit ecu, and electronic control unit ecu is connected with display screen and warning lamp；
Described pressure transducer is used for gathering the pressure on lorry levelling valve；
Described electronic control unit ecu is used for gathering the information of pressure transducer, and gross mass is shown on a display screen,
And the information of pressure transducer and threshold value are contrasted, if being more than threshold value, activate warning lamp.
Described display screen and warning lamp are arranged on the instrument board in driving cabin.
Described pressure transducer is arranged on the levelling valve on air suspension, and does not consider the feelings having lifting air bag
Condition, only considers the situation that air bag is even number, and pressure transducer number is the half of air bag number.
Described electronic control unit ecu has analog-to-digital conversion module.
Compared with prior art, device of the present utility model is adopted using the pressure transducer being arranged on truck air suspension
Pressure information on collection levelling valve, and changed and threshold comparison by electronic control unit ecu, if being more than threshold value,
Activation warning lamp, this device can accurately obtain the gross weight of loading lorry, and is shown by display screen, the setting of warning lamp
Can effectively adults phenomenon occur.
Further, pressure transducer of the present utility model is arranged on levelling valve, for direct measurement air bullet
Spring internal air pressure, each pressure transducer can measure two air spring air that respective heights control valve is controlled
Pressure.
Brief description
Fig. 1 is the schematic diagram of this utility model device.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described further.
Referring to Fig. 1, this utility model includes some pressure transducers being arranged on truck air suspension, pressure transducer
It is arranged on the levelling valve on air suspension, all pressure transducers are all connected to electronic control unit ecu, Electronic Control
Unit ecu is connected with display screen and warning lamp, and display screen and warning lamp are arranged on the instrument board in driving cabin；
Described pressure transducer is used for gathering the pressure on lorry levelling valve；
Described electronic control unit ecu has analog-to-digital conversion module, for gathering the information of pressure transducer, and will calculate
The gross mass of gained shows on a display screen, and the information of pressure transducer and threshold value are contrasted, if being more than threshold value,
Activation warning lamp.
Weighing method of the present utility model, comprises the following steps:
Step one, is acquired to the pressure on lorry levelling valve by pressure transducer, and pressure information is sent out
Deliver to electronic control unit ecu；
Step 2, electronic control unit ecu carries out analog digital conversion to the pressure information that each pressure transducer gathers；
Step 3, electronic control unit ecu calculates to each digital signal, calculates vertical load fi:
fi=2 (pi-pa) a (i=1,2...n) (1)
Wherein,
In formula, piAir spring internal air pressure measured by i-th pressure transducer；paFor external atmospheric pressure；a
Effective area for air spring；V is air bag volume；S is displacement of air bag；N is the number of pressure transducer；
Finally vertical load f suffered by corresponding each group air springi；
Step 4, the vertical load on all air springs and unsprung mass are made read group total, sprung mass msMeter
Calculation method is as follows:
Due to unsprung mass musFor certain value, thus primary Calculation preliminary quality m can be obtained0:
m0=ms+mus(4)
Step 5, preliminary quality passes through modifying factor correction, and modifying factor is the measured gross mass on on-ground weigher of lorry
With gross mass m measured by air suspension lorry self weighing device0Ratio be λ, then lorry gross mass m=λ m0；
Step 6, electronic control unit ecu sends lorry gross mass to display screen first, then by lorry gross mass with interior
Put threshold value to be contrasted；
Step 7, if lorry gross mass is more than threshold value m > mf, then warning lamp, m are activatedfFor built-in threshold value.
Method of the present utility model gathers the internal air pressure of air spring by pressure transducer, and is become mould
Intend the signal of telecommunication and pass to the analog digital conversion being connected, then electronic control unit ecu is to the digital signal obtaining after analog digital conversion
Carry out data processing, be calculated vertical load suffered by corresponding each group air spring, then read group total is made to above-mentioned data, enter
And can get sprung mass, because unsprung mass is certain value, primary Calculation this lorry gross mass can be obtained；For systematic error,
By, compared with fixing on-ground weigher, introducing modifying factor in the algorithm, and then more accurately gross mass can be obtained, can be more
Facilitate driver to obtain lorry gross weight in real time, efficiently control overweight phenomenon and occur.
