A torque sensor device disposed between an input shaft and an output shaft. The torque sensor device includes a housing, a magnet unit accommodated in the housing and including a magnet ring, a collector unit fixed in position to the housing, a sensing unit including a torque sensor disposed at the outer circumference of the collector unit, and a shield ring unit interposed between the collector unit and the magnet unit. The magnet unit includes: a magnet holder connected to the input shaft; a pair of magnet rings spaced apart from each other with the magnet holder interposed therebetween; a magnet cover formed in such a manner that the magnet ring is disposed between the magnet cover and the magnet holder so as to be connected to the magnet holder; and a magnet buffer disposed between the magnet cover and the magnet ring.

Torque sensor device

The present invention provides a torque sensor device disposed between an input shaft and an output shaft and configured to detect a torque between the input shaft and the output shaft through a relative rotation displacement therebetween. The torque sensor device includes: a housing configured to accommodate an end of the input shaft and an end of the output shaft and fixed in position to be able to perform a relative rotation with respect to the input shaft and the output shaft: a magnet unit accommodated in the housing and including a magnet ring connected to one end of one of the input shaft and the output shaft so as to be rotatably accommodated in the housing; a collector unit fixed in position to the housing in such a manner as to be disposed at the outside of the magnet unit, and configured to focus a magnetic field generated from the magnet unit; a sensing unit including a torque sensor disposed at the outer circumference of the collector unit and configured to detect the magnetic field focused by the collector unit; and a shield ring unit interposed between the collector unit and the magnet unit in such a manner as to be connected to one end of the other of the input shaft and the output shaft, and configured to change the magnetic field from the magnet unit, which is focused by the collector unit, by means of the relative rotation between the input shaft and the output shaft.
