Abstract:
1. A torsion angle and rotation angle measurement device comprising: an input rotation disk being connected with an input rotation driving source; an output rotation disk being connected with an output rotation target, and being coaxially and rotatably connected with the input rotation disk, the output rotation disk having a first gear wheel; at least two torsion measuring modules being disposed between the input rotation disk and the output rotation disk, each torsion measuring module comprising: a rotary variable resistor being disposed on the output rotation disk; and a torsion measuring arm being pivotally connected with the rotary variable resistor at an first end thereof and being slidably connected with the input rotation disk at an second opposite end thereof, wherein the rotary variable resistor measures an angle indicating the input rotation disk rotating relative to the output rotation disk when the input rotation disk rotates relative to the output rotation disk; and a rotation measuring module comprising: a printed circuit board; two rotary variable resistors being coaxially disposed on two opposite sides of the printed circuit board; and a gear wheel set being meshed with the first gear wheel and coaxially driving the two rotary variable resistors simultaneously, wherein the two rotary variable resistors measure a rotation angle of the output rotation disk when the output rotation disk rotates.
