Technical field
The present invention relates to a kind of sensor base for lever pressure transducer.
Background technology
Present highway administration increasingly develops to rapid and automation direction, and this just requires sensor must possess quickly and surveys the ability of vehicle weight in motion accurately and reliably.
Technology 1, road vehicle are weighed weighbridge:
The technology of weighbridge is the most highly developed, is mainly used as static weighing in the place such as factory, warehouse.But it is too slow to be because the response speed of weighbridge, bulky, trouble is installed, and the test of static state can only be done, the place with weighbridge or considerably less so highway and subsystem thereof are weighed, and the life-span of the foil gauge of its sensing is the shortest, the life-span only has three months；And its temperature influence is bigger.
Technology 2,9195GC (V) the cartridge type Intermediate Gray pressure head road vehicle of " KISTLER " company are 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 simple in construction, design is not the most complicated；But its technique it is difficult to ensure that, want to be made fore-and-aft direction diverse location and apply identical pressure and obtain and be not easy very much (because induction point can float) than more consistent measurement data.If it is inconsistent that fore-and-aft direction diverse location applies identical pressure measurement data, later data processes the most extremely complex.And theoretically, its service life is the longest, fatigue of materials elasticity there occurs change, and measurement data is the most 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 reducing the manufacture difficulty of sensor, but its original a lot of key functions just disappear, the reliability of certainty of measurement and measurement all cannot be compared with originally with the life-span.When fore-and-aft direction diverse location applies power, sensing result is the most inconsistent；It wants that doing accurate test can only make an effort from data process, but these data want to do accurately process extremely difficulty.And Open architecture, bad carries out water-proofing treatment.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of make under rougher manufacturing conditions precision more higher than sleeve sensors, be independent of 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 by the inconsistent problem of identical pressure sensitive point sensing.
nullIt is an object of the invention to be achieved through the following technical solutions: a kind of sensor base for lever pressure transducer，It includes sensor base top board、The sensor base top board strong point、Sensor base support arm、Sensor base induction pressure transmission lever junction point、Sensor base support arm support column、Sensor base induction pressure transmission lever、Sensor base support arm support column pressing plate、Sensor base pressure head and sensor base pedestal，Described sensor base top board passes through two symmetrical sensor base top board strong point sensor base support arms symmetrical with two respectively and is connected，Symmetrical with two the respectively sensor base support arm support column in the side of two sensor base support arms is connected，Two sensor base support arm support columns are connected with sensor base pedestal，Symmetrical sensor base support arm support column pressing plate it is provided with outside the middle part of two sensor base support arm support columns，The opposite side of two sensor base support arms passes through two symmetrical sensor base induction pressure transmission lever junction point sensor base induction pressure transmission levers symmetrical with two respectively and is connected，Two sensor base induction pressure transmission levers are connected with sensor base pressure head by two other symmetrical sensor base induction pressure transmission lever junction point，The installing hole matched with sensor sensing assembly it is provided with between sensor base pressure head and sensor base pedestal.
Described sensor sensing assembly includes sensor sensing assembly backing plate, sensor sensing assembly conductive plate and sensor sensing assembly support, sensor sensing assembly wafer it is provided with on sensor sensing assembly support, 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 conductive plate, and sensor sensing assembly conductive plate is connected with sensor sensing assembly support.
If applying 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 the two vector summation is equal is delivered to sensor base support arm by the sensor base top board strong point.Sensor base support arm passes to sensor base pressure head by the assembly of sensor base induction pressure transmission lever junction point and sensor base induction pressure transmission lever after power being distributed by a certain percentage, and at this moment its is the most equal by force vector summation.The two power that pressure head is subject to again can be according to certain pro rate to corresponding wafer, and the vectorial summation of the power that therefore the two power embodies on corresponding wafer is the most equal.
The invention has the beneficial effects as follows: (1) sensor base uses lever principle, is independent of elastic deformation, there is not fatigue of materials state, and life-span length was up to 2 years；(2) one-body molded, do not use bolt, it is ensured that concordance；(3) power that the point of all pressures is measured is identical, and the linearity is high, is convenient to later data and processes；(4) to requirement on machining accuracy well below the matrix of arc structure.
