Technical field
The present invention relates to a kind of sensor base for lever pressure transducer.
Background technology
Present highway administration is more and more to rapid and automation direction development, and this just requires sensor must possess fast and surveys the ability of vehicle weight in motion accurately and reliably.
Technology 1, road vehicle are weighed weighbridge:
The technology of weighbridge is very ripe, to be mainly used as static weighing in the place such as factory, warehouse.But because the reaction velocity of weighbridge is too slow, bulky, installs trouble, and can only do static test, so highway and subsystem thereof are weighed with the place of weighbridge or considerably less, and the life-span of the foil gauge of its induction is very short, and the life-span only has three months; And its temperature influence is larger.
9195GC (V) the cartridge type Intermediate Gray pressure head road vehicle of technology 2, " KISTLER " company is weighed pressure transducer:
The structure the earliest of highway LOAD CELLS, plays the part of the role of pioneer in the exploration of highway LOAD CELLS.Its structure is simple, and design is not very complicated; But its technique is difficult to ensure, want to do fore-and-aft direction diverse location applies identical pressure and obtains more consistent measurement data and be not easy very much (because induction point can float).If it is inconsistent that fore-and-aft direction diverse location applies identical pressure measurement data, late time data process is just very complicated.And theoretically, its serviceable life is not long, fatigue of materials elasticity there occurs change, and measurement data is also just along with there occurs change.
Technology 3, two sideband pull bar Intermediate Gray pressure head road vehicle is weighed pressure transducer:
Cartridge type Intermediate Gray pressure head road vehicle weigh pressure transducer reduction difficulty simplify version.That reduce the manufacture difficulty of sensor, but its original a lot of key functions just disappear, measuring accuracy all cannot compared with originally with the life-span with the reliability of measurement.When fore-and-aft direction diverse location applies power, induction result is certainly inconsistent; It is wanted to do accurately test and can only make an effort from data processing, but these data want to do accurately process extremely difficulty.And Open architecture, badly carries out water-proofing treatment.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, there is provided a kind of make under more coarse manufacturing conditions the precision higher than sleeve sensors, do not rely on elastic deformation, there is not fatigue of materials state, the sensor base for lever pressure transducer that the life-span is long, solve fore-and-aft direction or left and right directions diverse location responds to inconsistent problem by identical pressure sensitive point.
The object of the invention is to be achieved through the following technical solutions: a kind of sensor base for lever pressure transducer, it comprises sensor base top board, the sensor base top board strong point, sensor base sway brace, sensor base induction pressure transmission lever tie point, sensor base sway brace support column, sensor base induction pressure transmission lever, sensor base sway brace support column pressing plate, sensor base pressure head and sensor base pedestal, described sensor base top board is connected by the sensor base sway brace that two symmetrical sensor base top board strong points are symmetrical with two respectively, the sensor base sway brace support column that the side of two sensor base sway braces is symmetrical with two is respectively connected, two sensor base sway brace support columns are connected with sensor base pedestal, symmetrical sensor base sway brace support column pressing plate is provided with outside the middle part of two sensor base sway brace support columns, the opposite side of two sensor base sway braces is connected by the sensor base induction pressure transmission lever that two symmetrical sensor base induction pressure transmission lever tie points are symmetrical with two respectively, two sensor base induction pressure transmission levers are connected with sensor base pressure head by two other symmetrical sensor base induction pressure transmission lever tie point, the mounting hole matched with sensor sensing assembly is provided with between sensor base pressure head and sensor base pedestal.
Described sensor sensing assembly comprises sensor sensing assembly backing plate, sensor sensing assembly current-carrying plate and sensor sensing assembly support, sensor sensing assembly support is provided with sensor sensing assembly wafer, the outside of two described sensor sensing assembly backing plates is connected with sensor base pressure head and sensor base pedestal respectively, the flat side of two sensor sensing assembly backing plates is connected with sensor sensing assembly current-carrying plate, and sensor sensing assembly current-carrying plate is connected with sensor sensing assembly support.
If apply equal pressure at sensor base top board fore-and-aft direction diverse location, equal pressure will be transformed on the sensor base top board strong point, and at this moment two strong points is equal by force vector summation.The power that these two vectorial summations are equal is delivered to sensor base sway brace by the sensor base top board strong point.Pass to sensor base pressure head by the assembly of sensor base induction pressure transmission lever tie point and sensor base induction pressure transmission lever after power is distributed by sensor base sway brace by a certain percentage, at this moment its is also equal by force vector summation.These two power that pressure head is subject to again can according to certain proportional distribution to corresponding wafer, and therefore the vectorial summation of power that embodies on corresponding wafer of these two power is also equal.
The invention has the beneficial effects as follows: (1) sensor base adopts lever principle, and do not rely on elastic deformation, there is not fatigue of materials state, life-span length can reach 2 years; (2) one-body molded, do not adopt bolt, ensure consistance; (3) power measured of the point of all pressures is identical, and the linearity is high, is convenient to late time data process; (4) to the matrix of requirement on machining accuracy well below arc structure.
