Abstract
A torque transducer has a circumferentially magnetized sleeve press fitted on the user-tiltable portion of a vehicle steering shaft and disposed axially intermediate the shaft support bearings. A stationary pickup coil is mounted over the sleeve and located with respect to the sleeve by a second pair of bearings. In an alternate embodiment, two circumferentially magnetized, axially spaced sleeves are utilized.
