Technical solutions of the utility model have the following advantages that：
1. sensor provided by the utility model, including two stress induction teeth being mutually connected vertically, it is answered described in two
The equitant position of power induction tooth is provided with the foil gauge of elongation synchronous with the stress induction tooth or contraction, the foil gauge packet
It includes：Two horizontally extending horizontal force foil gauges set and two are perpendicular to one another, setting is answered in two horizontal forces
Become the vertical force foil gauge between piece.
In the utility model, by sensor application provided by the utility model on bearing beam, when travelling machine on bearing beam
When motor-car, the size for the horizontal force for being parallel to bearing beam direction can be measured in horizontal force foil gauge, when vehicle carry out start or
Person brake when, the acceleration of vehicle is not zero at this time, and vehicle is in non-at the uniform velocity state, horizontal force action on bearing beam, according to
Direction is respectively acting on one tensile stress of generation, a compression, two signals detected on two horizontal force foil gauges
Polarity exchanges link, just will draw, compression superposition, and obtain the horizontal force (brake force) acted on bearing beam.
Vertical force foil gauge is used for measuring vertical force, and vertical force foil gauge is mutually perpendicular to and is in that 45 degree or 135 degree of angles are arranged,
By sensor application provided by the utility model on bearing beam, when bearing beam is by downward load, the phase inside bearing beam
Adjacent two stress units all can be by shearing force, from the angle of force analysis it is found that the direction of shearing force is along 45 degree or 135
Spend direction.Vertical force (load) acts on the region between two vertical force foil gauges on bearing beam, is answered in two vertical force
Become piece position and generate shearing, the sum of two shearings are the vertical forces (load) between acting on two sensors, two at this time
The numerical value that vertical force strain measurement obtains is the size of the load suffered by bearing beam.
In vehicle braking or accelerator, horizontal force is will produce between tire and road surface, simultaneously as the effect of inertia
Vehicle's center of gravity can be made to move forward or move afterwards, thus influence the detection of vehicle wheel load.
By the detection to horizontal force, coordinate the numerical value of load, vehicle braking or the degree of acceleration is can determine whether, to correct
The error that vehicle load detects caused by braking.Reduce vehicle in detection zone the error caused by traveling lack of standardization.Simultaneously
Vehicle braking performances can be detected, as brake force size, brake force or so are unbalanced and the braking of antero posterior axis or axis group
Sequential.
