In the prior art, it is generally weighed using load of the weighbridge to semitrailer.But weighbridge is bright with place limitation
Aobvious defect can not achieve and be weighed whenever and wherever possible to the load of semitrailer.Accordingly, it is desirable to provide one kind can be whenever and wherever possible
The semitrailer vehicle-mounted weighing system weighed.
Fig. 1 is the mounting structure schematic diagram of weighing sensor in semitrailer vehicle-mounted weighing system.Fig. 2 is shown in FIG. 1 half
The mounting structure schematic diagram of displacement sensor in trailer vehicle-mounted weighing system.Fig. 3 is semitrailer vehicle-mounted weighing system shown in Fig. 2
Partial enlarged view.
As shown in Figures 1 and 2, the semitrailer vehicle-mounted weighing system provided in an embodiment of the present invention, including weighing
Sensor 20, displacement sensor 30 and controller (not shown).
Weighing sensor 20 includes at least one.Weighing sensor 20 is set to the bottom of traction pin mount 100.Specifically
Into embodiment shown in FIG. 1, weighing sensor 20 be fixedly connected on traction pin mount 100 bottom and towing plate 700 it
Between, towing plate 700 is fixedly connected on to the bottom of traction pin mount 100.In this way, the setting of towing plate 700 avoids title
It retransmits sensor 20 directly to contact with the traction saddle of tractor, causes the damage of weighing sensor 20.In order to guarantee weighing and sensing
Device 20 is weighed accurately, without direct rigid contact between towing plate 700 and traction pin mount 100 and towing pin 200.
Displacement sensor 30 is installed between the opposite end of the vehicle bridge 300 of semitrailer and the vehicle frame 400 of semitrailer.Displacement
Sensor 30 is for detecting the distance between 300 opposite end of vehicle bridge and vehicle frame 400.
Controller is connect with weighing sensor 20 and displacement sensor 30, and controller is configured as according to weighing sensor 20
300 opposite end of loading load and vehicle bridge that traction pin mount 100 is born is obtained with the detection data of displacement sensor 30
The loading load born, to obtain the loading load of semitrailer.
At least one weighing sensor is arranged in the bottom of traction pin mount 100 in above-mentioned semitrailer vehicle-mounted weighing system
20, so that the cargo being loaded on vehicle frame 400 passes sequentially through vehicle frame 400, traction pin mount 100, each weighing sensor 20
By the traction saddle of part cargo shipment load transmission caused by cargo to tractor.Traction pin mount is transferred to by vehicle frame 400
100 loading load is the sum of the loading load that each weighing sensor 20 is born.Controller is according to weighing sensor 20
Detection data acquire the loading load born of traction pin mount 100, i.e., by the testing number of each weighing sensor 20
The loading load that traction pin mount 100 is born is obtained according to addition.
Also, it is mounted on displacement between the opposite end of each vehicle bridge 300 of semitrailer and the vehicle frame 400 of trailer to pass
Sensor 30, for detecting the distance between corresponding 300 opposite end of vehicle bridge and vehicle frame 400.Controller is passed according to each displacement
The detection data that sensor 30 detects obtains the loading load that 300 opposite end of vehicle bridge is born respectively.Controller is again to traction
The loading load that the loading load and 300 opposite end of vehicle bridge that pin mount 100 is born are born sums up to get arriving
Semitrailer total loading load.In this way, realize can the loading load to semitrailer weighed anywhere or anytime, not by ground
The limitation of point.
It should be noted that above-mentioned loading load refers to load caused by the cargo being loaded on vehicle frame 400.Example
Such as, the cargo that the loading load that traction pin mount 100 is born as is loaded on vehicle frame 400 is to traction pin mount 100
Generated load.The cargo that the loading load that 300 opposite end of vehicle bridge is born as is loaded on vehicle frame 400 is to the vehicle bridge
Load caused by 300 opposite ends.
It should also be noted that, being needed before detection loads load to exclude the influence of the equal components self weight of vehicle frame 400
Zero point is demarcated to each weighing sensor 20, i.e., in semitrailer light condition, set the load of each weighing sensor 20 as zero.
Similarly, it is also necessary in semitrailer light condition, detect corresponding vehicle bridge 300 opposite two using each displacement sensor 30
Relative distance between end and vehicle frame 400.Specifically, the loading load that 300 one end of vehicle bridge is born can pass through following formula meters
It calculates:
Fi=(L0-Li) × Ci；Wherein: the loading load that Fi is born by 300 one end of vehicle bridge, unit N；L0 is semi-mounted
The distance between displacement sensor 30 detects when vehicle zero load 300 one end of vehicle bridge and vehicle frame 400, unit m；Li is half
Trailer loads the distance between 300 one end of vehicle bridge for detecting of displacement sensor 30 and vehicle frame 400 in the state of cargo, unit
For m；Ci is the rigidity of suspension, unit N/m.It is understood that when semitrailer uses Leaf Spring Suspension, suspension 500
Rigidity be leaf spring rigidity.The distance between the vehicle frame 400 detected according to displacement sensor and vehicle bridge 300 obtain
The loading load of 300 opposite end of pick-up bridge, has more detailed description, therefore details are not described herein in the prior art.
