Patent ID: 6854343

Claim:
A Sensor for detecting the torque on a shaft having two coaxially arranged portions, the first and second portions being connected by a torsion bar so that a torque acting on the shaft can be evaluated by the twisting of the torsion bar, the sensor comprising: a disc-shaped movement converter being connected to the first portion of the shaft such that a torsion in the torsion bar produces an angular movement of the movement converter, a carrier surrounding the shaft and being floatingly mounted thereon with a fit, a first end of the carrier being directed toward the movement converter and mechanically connected thereto in such a way that the angular movement of the movement converter is converted into helical forces acting on the carrier, a second end of the carrier is located to be in cooperation with a movement guide being mechanically connected to the second portion of the shaft in such a way that the carrier cannot move helically but only linearly in the axial direction on the shaft, and a displacement sensor positioned adjacent the carrier so that the torque of the shaft can be determined by the angular movement converted into an axial translation movement of the carrier.
