Abstract
A torque detector, particularly a torque detector for detecting a torque applied to a torque transmission shaft which is connected to a load such as a wheel of an automobile, has a driving member connected to an engine, a driven member connected to a load and driven by the driving member to be rotated, an elastic member for connecting the driving member to the driven member, a transmission for varying the rotating speed ration of the engine to the load, which is provided in the driving member or the driven member, electromagnetic pickups for detecting the angular phase difference between the driving member and the driven member which is produced due to the deformation of the elastic member, a rotating speed ratio counting circuit for detecting the rotating speed ratio of the engine to the load, which is controlled by the transmission, and a microcomputer for calculating engine torque and load driving torque from the rotating speed ratio detected by the rotating speed ratio counting circuit and the angular phase difference detected by the electromagnetic pickups.
