Abstract: |
A torque transducer in photoelectric type for vehicle belonging to special electronic equipment of transport vehicle is a photoelectric torque transducer in non-contacting type, which mainly composes of two photoelectric cells, a light-transparent arm with light-transparent hole and a light barrier arm with light-uiding hole, luminous diode, torsion bar and pencil of conducting line. The light transparent arm and light barrier arm are fixed at two ends of torsion bar separately, the photoelectric cell and luminous diode will be placed at outer side of light-transparent arm and light barrier arm separately and the conducting wires of photoelectric cell and luminous diode will be connected with outside through winding box. The invented transducer has simple structure, high accuracy measurement and no limitative of measuring range and it is especially good for measurement of steering torque in power-assisted steering system. |
