Embodiment 1

As shown in Figure 1, 2, a kind of meausring apparatus for vehicle load, comprising:

At least one group of sensor, wherein often organize sensor and comprise at least two obliquity sensors 6, all obliquity sensors 6 often organizing sensor are all located on the vehicle frame 1 of vehicle;

Data handler 7, for being electrically connected all described obliquity sensor 6 often organizing sensor.

Above-mentioned sensor of often organizing comprises at least two obliquity sensors 6, on vehicle frame 1, two normal angles of any two obliquity sensors 6 relative place vehicle frame 1 sensitive face are set to θ, as shown in Figure 3, what this angle theta was corresponding is when car load acts on vehicle frame 1, be delivered to the deformation (or degree of disturbing) that vehicle frame 1 causes, this deformation quantity and load weight (abbreviation load-carrying) directly related, measured by data handler 7 and calculate this angle theta or angle variable quantity △ θ export voltage signal, obtain the corresponding vehicle load value M of this vehicle frame 1.

General, automobile chassis frame 1 bearing load weight, transversely can there is small bending, general bending towards direction, ground, about the relation of loading force and vehicle frame 1 deformation, the same with the variation relation of loading force and spring plate 4, all there is the principle of linear relationship, be known technology (as: Li Yishi. based on finite element certain Multi-Leaf Springs performance simulation research [D]. Changsha: Hunan University machinery with delivery engineering college .2007:36-37).Therefore being out of shape corresponding degree of disturbing variable quantity by detecting vehicle frame 1, just can calculating vehicle load value or load-carrying changing value.

Consider automobile, especially lorry, truck tanker, mixermobile, the middle bearing load heavier-weight of its vehicle frame 1, two ends are comparatively light, and vehicle frame 1 can bend, and the bending direction of vehicle frame downward, when load weight changes, the bending curvature of vehicle frame 1 also can change.Assuming that degree of the disturbing variable quantity γ that vehicle frame 1 is out of shape, the variable angle θ of two corresponding obliquity sensors 6, its principle of measurement is the same.As shown in Figure 4, the load weight being reduced to vehicle frame 1 model loads before and after change, the intersection point being positioned at the corresponding sensitive surface normal of two obliquity sensors 6 on vehicle frame 1 is the center of circle is O and O ', radius is respectively R and R ', the angle of two obliquity sensors 6 is respectively θ and θ ', on the corresponding vehicle frame 1 in these two centers of circle, between two obliquity sensors 6, link pitch is respectively L and L ', and the chord length of two centers of circle and two obliquity sensor 6 lines is respectively d and d ', it can thus be appreciated that:

Loading the front center of circle to the distance of chord length is:

$d=\frac{\frac{L}{2}}{\tan \frac{\mathrm{\θ}}{2}}$

Before loading, radius of circle is:

$R=\frac{\frac{L}{2}}{\sin \frac{\mathrm{\θ}}{2}}$

Before loading, circular arc length is:

$h=2\mathrm{\π}R\frac{\mathrm{\θ}}{2\mathrm{\π}}=R\mathrm{\θ}=\frac{\frac{L}{2}}{\sin \frac{\mathrm{\θ}}{2}}*\mathrm{\θ}$

After loading, front circular arc length is constant with loading is still:

$h=\frac{\frac{L}{2}}{\sin \frac{\mathrm{\θ}}{2}}*\mathrm{\θ}$

Therefore after loading, radius is:

$R^{\′}=\frac{\frac{L}{2}*\mathrm{\θ}}{sin\frac{\mathrm{\θ}}{2}*{\mathrm{\θ}}^{\′}}$

After loading, the center of circle to the distance of chord length is:

$d^{\′}=R^{\′}\cos \frac{{\mathrm{\θ}}^{\′}}{2}=\frac{\frac{L}{2}*\mathrm{\θ}}{\sin \frac{\mathrm{\θ}}{2}*{\mathrm{\θ}}^{\′}}*\cos \frac{{\mathrm{\θ}}^{\′}}{2}=\frac{\frac{L}{2}*\mathrm{\θ}*\cos \frac{{\mathrm{\θ}}^{\′}}{2}}{\sin \frac{\mathrm{\θ}}{2}*{\mathrm{\θ}}^{\′}}$

Load before and after distance of center circle from for:

$\mathrm{\Δ}R=R^{\′}-R=\frac{\frac{L}{2}*\mathrm{\θ}}{sin\frac{\mathrm{\θ}}{2}*{\mathrm{\θ}}^{\′}}-\frac{\frac{L}{2}}{\sin \frac{\mathrm{\θ}}{2}}$

So steel spring loads front and back degree of disturbing variable quantity be:

$\mathrm{\γ}=d^{\′}-d-\mathrm{\Δ}R=\frac{\frac{L}{2}*\mathrm{\θ}*\cos \frac{{\mathrm{\θ}}^{\′}}{2}}{\sin \frac{\mathrm{\θ}}{2}*{\mathrm{\θ}}^{\′}}-\frac{\frac{L}{2}}{\tan \frac{\mathrm{\θ}}{2}}-(\frac{\frac{L}{2}*\mathrm{\θ}}{\sin \frac{\mathrm{\θ}}{2}*{\mathrm{\θ}}^{\′}}-\frac{\frac{L}{2}}{\sin \frac{\mathrm{\θ}}{2}})$

Be directly proportional can obtain because weighing load and loading force F change γ to vehicle frame 1 degree of disturbing:

F=K* γ (K for demarcate constant) is namely:

$F=K*\mathrm{\γ}=K*=\{\frac{\frac{L}{2}*\mathrm{\θ}*\cos \frac{{\mathrm{\θ}}^{\′}}{2}}{\sin \frac{\mathrm{\θ}}{2}*{\mathrm{\θ}}^{\′}}-\frac{\frac{L}{2}}{\tan \frac{\mathrm{\θ}}{2}}-(\frac{\frac{L}{2}*\mathrm{\θ}}{\sin \frac{\mathrm{\θ}}{2}*{\mathrm{\θ}}^{\′}}-\frac{\frac{L}{2}}{\sin \frac{\mathrm{\θ}}{2}})\}$

By variable angle θ and the θ ' of two obliquity sensors 6, just can calculate degree of the disturbing variable quantity of vehicle frame 1, thus extrapolate loading force F vehicle frame 1 often being organized sensor, so on vehicle frame 1, all the sensors loading force sum is exactly the load carrying ability M of vehicle.
