Title:
TORQUE INDEX SENSOR HAVING STRUCTURE FOR MAGNETIC SHIELDING
Document Type and Number:
WIPO Patent Application WO/2012/015183
Kind Code:
A2
Abstract:
The present invention relates to a TIS (torque index sensor) having a magnetic shielding structure, formed with a shield plate between a torque sensor unit and an index unit to minimize the magnetic interference therebetween for operational reliability and to make the TIS compact for maximization of utilization of space, the TIS including: a torque sensor unit including a rotor connected to the input shaft, a stator connected to the output shaft, a collector and a torque sensor magnetic device; an index unit including an index magnet rotating along with the output shaft, and an index magnetic device detecting changes in magnetic field in response to rotation of the index magnet; and a shield plate interposed between the torque sensor unit and the index unit for shielding a magnetic interference between the torque sensor unit and the index unit.
