실차 상태 차량의 동력 조향 펌프 토크 측정

Recently not only the efficiency of an engine but also that of accessories powered by an engine is getting more important. To improve the efficiency of accessories, it is necessary to measure the accurate torque of accessories. But to measure the torque of each accessories needs much efforts and high cost for modifying the test vehicles. So we developed torque meter which is available to measure the torque in-vehicle. Torque is measured by strain gage sensor and there are also four channel thermocouples and RTD to check the temperature. And non-contacting power transmission method and Bluetooth wireless data transmitting technology are used. In this paper, we measured the t α que of power steering system. The torque of power steering pump is measured successfully.
