Claims
- 1. A device for measuring action force of a wheel comprising:
- a vehicle axle is formed with a hole therein and has a natural stress axis;
- a stress detection sensor installed in said hole and secured therein through contact between lateral sides of said stress detection sensor and an inner surface of said hole, said stress detection sensor being aligned with or proximate said neutral stress axis such that axle torque effect on said stress detection sensor is minimized;
- said stress detection sensor being an integral unit comprising said strain gauges mounted on a cubic plastic base;
- a spacing means for potting said stress detection sensor in said hole;
- a signal processing circuit for processing said detection signal from said stress detection sensor to minimize an axle torque component;
- a cylindrical housing containing said signal processing circuit and secured in said hole by said spacing means;
- wiring means for interconnecting said signal processing means with outputs of said stress detection sensor within said hole; and
- output means for permitting said signal processing circuit to output a stress detection signal from said hole.
