Patent JP-H02128129-A (JP)
Title: Torque sensor
Inventor: NAKAMURA YOSHINOBU
IPC: G01L3/10
Filed: 1988-11-08
Abstract: PURPOSE:To enable a higher torque detection accuracy along with a decrease in an output detection exciting current value by a method wherein a change in magnetic characteristic of a magnetic metal sheet band is detected based on outputs of a group of detection coils connected together differentially and a detection output thereof is corrected by outputs of a group of detection coils cumulatively connected together. CONSTITUTION:When a torque is applied to a torque transmission shaft 11, magnetic characteristics of magnetic metal sheet bands 12 and 13 change. An exciting current flows to exciting coils 16a-16d and 18a-18d at even sets of detection magnetic cores 14a-14d and 15a-15d, for example, four each set, so arranged as to be excited in a circumferential direction of the sheet bands 12 and 13 beforehand. If so, a detection voltage is outputted according to an applied torque from detection coils 17a-17d and 19a-19d in response to the change in the magnetic characteristics so that an exciting current value can be reduced. At this point, as outputs of one group of detection coils cumulatively connected together out of the groups of detection coils give signals indicating characteristic changes of the detection coils, a higher torque detection accuracy is achieved by correcting outputs of the residual groups of detection coils differentially connected by an output thereof.
