DEVICE FOR MEASURING A TORQUE OF A DRIVING SHAFT IN AN ELECTRIC VEHICLE BY CONTAINING A TORQUE SENSOR, A TRASCEIVING UNIT AND A DISPLAY UNIT

摘要

PURPOSE: A torque sensor of a driving shaft in an electric vehicle is provided to measure the torque characteristic of the driving shaft in a real time. CONSTITUTION: A torque sensor(100) detects a torque of a driving shaft by installing the driving shaft of an electric vehicle. Transceiver units(102-106) transmit and receive the torque of the driving shaft detected through the torque sensor. A display unit(108) displays a waveform corresponding to the torque of the driving shaft transferred through the trasceiver units. Thereby, the torque characteristic of the driving shaft is precisely measured in a real time. Moreover, the torque characteristic is monitored during a driving of the electric vehicle and the actual torque waveform is obtained without checking the torque characteristic of the driving shaft through a torque measurement of a motor.
